adopts the solar energy principle made by the photovoltaic effect principle. During the daytime, the solar panel receives the solar radiation and converts it into electric energy output. The solar LED street light is stored in the battery through charge and discharge control, and the night illumination gradually decreases to about 10LX, and the solar panel voltage is gradually reduced. It is about 4.5v, the charge and discharge control device detects the voltage after the operation, the light source of the battery discharge, the battery discharge set time, the charge and discharge control operation, and the solar LED street light completes the battery discharge.
Solar panels reach 127Wp / m2 solar power, high power, the system is conducive to windproof planning; some lamps are integrated into the printed circuit board with 1W white LED and 1W yellow LED, arranged as a planar light source with a grid of certain spacing.
The control box body is made of stainless steel, which is beautiful and elegant. The control box is placed with maintenance-free lead-acid battery and charge and discharge control. The system uses a valve-regulated sealed lead-acid battery, because it has little maintenance, so it is also called "maintenance-free battery", which is conducive to the system maintenance cost reduction; the planned charge and discharge control coordination completion function (with light control, Time control, overcharge maintenance, over-maintenance and reverse maintenance, etc.) and capital manipulation to complete high prices.

where it cools rapidly to a temperature at which it hardens sufficiently to maintain the contour of the stamp. For this reason, the temperature of the furniture mould is important because it controls a portion of the entire moulding cycle. Although the melt moves more freely in the hot mould, it is necessary to increase the cooling time so that the cured moulded article can be discharged. On the other hand, when the melt cures immediately in the cold mould, it may not reach the end of the cavity completely. Therefore, the trade-off between the two extremes must be accepted in order to achieve the best moulding cycle.
Units for circulation of water (or other fluids) are commercially achievable. The device is fully connected to the mould by a flexible hose, and the heat of the furniture mould can be kept within limits. The use of plastic moulds in connection with cold water supply selection techniques is unlikely to result in intensive heat treatment.
This is basically the mould designer's obligation to provide a suitable circulation strategy within the mould. Usually, the simplest strategy is to drill longitudinally through the furniture mould. On the other hand, this is not necessarily the most effective mould method.
On the other hand, once drilling is used for the flow of the coolant, these should not be too close to the indentation (less than 15 mm), as this may result in significant temperature changes throughout the process, resulting in moulding difficulties.
The design of the circuit is often complicated because it is not possible to drill very close channels near any other holes in the same template. It can be recalled that the template has a large number of holes or grooves to accommodate the thimble, the guide post, the guide sleeve, the gate bushing, the insert, and the like. The proximity of the flow pattern to how close the other hole depends largely on the depth of the hole required for the desired flow pattern. When drilling deep runners, the borehole tends to deviate from its prescribed path. The usual guiding device is that for drilling holes up to 149 mm in depth, the flow pattern must be no less than 3 mm to any one hole. For deeper flow patterns, this allowance is increased to 6 mm.
In order to obtain the perfect achievable position of the circuit, it is a good practice to lay the circuit as early as possible in the design. An alternative mould comprising a thimble, a guide bushing or the like can then be positioned accordingly.

consists of two or more stamps that can be custom moulded to different parts. Polymers are being successfully applied in furniture moulds. As with any alternative polymer, they must be balanced to flow into unique components. Most components should be filled evenly and evenly. Otherwise, uneven packaging can occur; many components will be over-wrapped and subjected to high stresses, causing warpage, and other components will be packaged or not completely filled. Note: Furniture moulds should be avoided as much as possible because it is difficult to obtain a balanced flow. If a furniture mould is required, the flow should be balanced by changing the diameter of the flow path, not the gate size.
The polymer has excellent gloss and is ideal for extracting furniture moulds. Keep in mind that polishing a smoother surface than required for polishing will only increase the cost of the furniture mould. In most cases, extremely polished surfaces can hinder ejection if the vacuum is typically applied with minimal or no drafting. Where there is no vacuum, the polished surface usually bounces better.
Reduce the possibility of creating a vacuum during ejection. Repair furniture mould surface texture can be used to hide weld lines, flow marks, gate blush, sink scars and scratches. There are hundreds of standard modes to choose from. Basically, anything that can be drawn in black and white can be used as the basis for a texture pattern.
It is important to determine the texture pattern early in the design process in order to incorporate the appropriate draft angle and contour directly into the part.

Ten LED street lights were installed on the streets of the home to illuminate the night before, which is part of the project launched by Led street lights Manufacturers(CLASSIC) https://www.classicledlight.com/
in China.
The Transportation and Municipal Public Administration has informed reporters that the agency has begun a project to convert traditional high-pressure sodium lamps into more energy-efficient LED street lights with 187 lights in 16 lanes. Enforced by the Weicheng District and LED street lights manufacturers, the project is dedicated to illuminating the night and reducing accidents accordingly. So far, all installation operations have been completed.
City officials said the new product will last longer than traditional lamps. High efficiency provides high brightness without consuming too much energy. High CRI can bring higher visual fidelity and help residents see more realistic colors. Bright lights attract more visitors.
This streetlight replacement program is provided by Wucheng District and China LED street lights manufacturers. After the project is completed, the authority can better control these lights for maintenance.

that forms an internal top layer feature including holes, pockets, and grooves. The punch can also take the injection moulded part from a thicker position to maintain a uniform wall size. Where practicable, we should reasonably design the components so that the punches can be independently separated from the components in the mould opening path. Alternatively, you may need to add sliders or hydraulic shifting punches, which may increase the cost of custom furniture mould manufacturing and storage.
In general, the depth to diameter ratio of closed cells should not exceed 3.5:1. A percentage of approximately 4.8:1 is feasible if the filling progress is symmetrically around the unsupported punch or if the punch is in a slowly moving area. Consider the option component blueprint to prevent fine punching that takes a long time. If the punch is supported on each side, the rule of length to diameter ratio is doubled: typically 6:1, but if the fill around the punch is symmetrical, it is about 10:1.

have a negative impact on visual function (including vision, contrast sensitivity, view), color perception). And it provides some lighting design solutions for the elderly and low vision people in the office and public lighting environment.
When a person's age is over 45, internal light scattering increases, spatial contrast sensitivity and retinal brightness decrease, and vision will decrease at any time. According to a study by the World Health Organization, more than 285 million people worldwide suffered from visual impairment in 2017, and this situation is getting worse as the problem of aging becomes more serious. This is a problem we cannot ignore.
In the previous report, there was some information on how lighting can damage people's eyesight. They provided some suggestions. However, this report improves these programs related to the current social environment based on current research.
1. Lower ages for older people range from 65 to 50 and increase some lighting requirements in offices and other public areas.
2. Analyze the negative effects of poor lighting on the vision of the elderly and provide some design recommendations primarily for the elderly and low vision.
3. Analyze some design methods in a detailed example.
According to the report, people are older and have a higher proportion of the disease. Therefore, in order to protect the vision and health of the elderly from these bad LED street lights manufacturers, what should be done to pay attention to the lighting design.

may only have one stamp or multiple, sometimes as many as 100, depending on the size of the component. Furniture mould typically produces similar components, but one type of mould, commonly referred to as a "family" mould, is used to make the various components, which are then assembled into individual components.
The main structural component of the furniture mould is the mould baffle, which is locked together by the use of pins and bushings to maintain and align the inner working parts with the mould. In operation, one piece of furniture mould part is held in a secured state on the moulding machine. The other half is removed from the fixed portion to complete the mould closing and opening. The fastening portion from the mould contains a method for transporting the molten polyester resin into the passage therein.
The method consists of an inlet (runner) coupled to it (channel) to transport the polyester resin from the runner to the gate (inlet). The component ejection mechanism is usually fixed in the displacement portion from the mould. The furniture mould is designed using a cooling method to remove heat from the heat of fusion.
The polyester resin within the impression and thus the sale of components or components. Rapid cooling reduces machine injection time and enhances manufacturing while cooling and charging evenly.
Warpage or excessive shrinkage is prohibited by the component. Even component cooling requires that most of the condensing cooling occurs near the hottest point (ie, near the gate and inlet, and within the different sized components, in the largest sized position).

have become a global trend, providing brighter light and better visibility to residents around the world to reduce costs and carbon emissions.
Benefiting from the development of electrical technology, street lighting products have evolved from previous fuel-powered lamps to sodium-filled bulbs and LEDs. At present, new luminaires with smart sensor LED street lights can be automatically turned on or off according to changes in the surrounding environment.
A company from Norway has developed almost a new system that automatically dims according to the presence of traffic. Each lamp is equipped with sensors for detecting vehicles and pedestrians. With the support of LED street light manufacturers, these lamps can significantly reduce energy costs with new LEDs.
When a person or vehicle approaches, it emits a brighter glow to provide a brighter visual effect. If it does not detect any objects in motion, it dims the lamp at low power to reduce unnecessary power consumption.
When such a lamp supported by the LED street lights manufacturers are put into use, it is estimated that about 40% of the energy will be reduced compared to before applying.

and injection moulding industry, you should not ignore the Chinese market. With the rapid development of the economy, it has become the center of the world's plastic mould manufacturers and injection moulding plants. But if you decide to outsource some table mould making or injection moulding business in China, how to find a list of table mould manufacturers will be your first challenge.
Finding a table mould maker in China is an absolutely tough job. It uses the survey process to make it the most consistent with the business model. This method assumes that all requirements and goals have been understood. There is no clear requirement that these jobs may be futile.
For potential suppliers, the best resources are Internet and industry publications. And the corresponding information should be compared and sorted according to logic. A screening list should be prepared prior to the investigation.
This process should avoid ambiguity and should be specific and clear. The goal is to find out if the supplier is compliant with the RFP requirements. The final table mould manufacturer should be able to meet these requirements. Then you can decide the final choice among them.

. The move is the latest agreement by the city manager authorized by the Lindsay City Council to convert street lights from all cities into LEDs.
There are currently about 574 street lights burning in the Lindsay network. Current lamp power ranges from 70 watts to 250 watts, with most of the power being 70 watts (434) and 150 watts (102). They all consume a lot of electricity on their annual energy bills. Street light suppliers offer more energy efficient LED lights when all street light replacement plans are completed. While providing the same lighting effect, considerable energy costs will be cut accordingly.
A spokesperson pointed out that local authorities seized the opportunity to upgrade this streetlight network from high-pressure sodium lamps to LED street lights. He said that the high-pressure sodium lamp that was introduced around 1970 became a popular street lighting solution because of its excellent results. However, compared to the current improved new energy technologies, HPS products are certainly at a disadvantage of their many defects.
The HPS lamp emits yellow light, while the LED emits white light, limiting visibility and lumen depreciation. Unlike traditional high-pressure sodium lamps that contain large amounts of mercury vapor, LED street lamps do not contain previous materials if they are released into the environment. It is environmentally friendly and environmentally friendly. LEDs convert all electrical energy into light energy while reducing heat, thereby reducing energy waste. High color rendering ensures a more realistic color performance. In addition, LEDs last more than 10 years longer than HPS products.
The replacement plan provided by the LED street lights manufacturers will take effect in 2019. It is estimated that this move will bring more and more convenience to the public and residents.

design for hot manifold operation is to balance the runner system and calculations that will effectively cool the cavity clusters. Thermal insulation of the thermal manifold is achieved by including an air gap and a minimum contact area between the hot and cold portions of the mould. Double the air gap interval can increase the insulation effect by 8 times. The hot runner plate must not contact the mould part in any way other than the minimum support area necessary to separate the parts.
Through asbestos, glass bonded mica is typically used to minimize heat transfer from hot parts to cold parts. Glass bonded mica is advantageous because it can be ground to absolute flatness and the same parallelism as steel, and it has overall dimensional stability of up to 700 °F. The differential expansion between the hot manifold element and the cooler table mould part must be allowed.
This is typically accomplished by arranging a sliding table mould portion between the manifold plate and the integrated gate plate. The flat floor provides the necessary sliding surface or a cylinder unit can also be used. Certain types of probes or hot tip bushings are used with the ring gate to maintain the temperature at the manifold outlet. The manifold and tip are heated to maintain the barrel temperature in the compound.
The minimum manifold area follows the cavity layout pattern and the manifold is cut into a minimum profile containing the flow channels and heating elements. Basic manifold design considerations include heaters that are parallel to the internal flow channel. Thermocouples that maintain the desired temperature are essential.
Since the hot tips are forwardly indexed by a cavity that is cooler than the manifold, they must move freely to compensate for their different expansions. A positive seal must be maintained between the bushing and the manifold. By sliding in the holes of the spruce bushing or nozzle and in the bore, the hot runner can freely expand in the direction of the fixed end. The slidable end is sealed by a specially designed metal seal.
In some cases, dispensing a wheel set may require an external heating tip from a controlled source, heating the probe, hot gate bushings, and heater castings are important to improve hot manifold forming. By heating the runner tip in the thermal control gate, the melting time is extended and the material does not freeze in the runner. The gate and probe are heated by encapsulation in a cast beryllium copper body or by the use of internal heating elements, and in some cases, thermocouples are also included.

continue to be produced in troubled machines, and continued operation of household products mould that have begun to squeak or scream will cause damage. If the operation is allowed to continue without ending the problem, the household product mould that refuses to be normally closed or opened will be damaged, or the mould will not be ejected normally. An alert and well-trained foreman can hear trouble when passing through the moulding room. Mould damage of the above type is not limited to the printing shop. Tool room technicians failed to tighten the screws through incorrect mould assembly, leaving metal shavings, abrasive dust or polishing abrasives on or near the sliding surface to contribute their share.
Fatigue is the main cause damage in household products mould, which results in the destruction of household products mould that are subjected to maximum stress while prolonged circulation. This usually happens if it will occur after 100,000 and 300,000 moulding cycles. In a multi-cavity mould, the same components as the first broken component can last for a limited longer period of time. Fatigue can be manifested in components that are subjected to compressive loads as well as in torque, tension or bending components.
Thermal shock has a questionable contribution to the deterioration of household products mould. As far as our analysis is concerned, unless the rapid heating and cooling of the household product mould is part of the cycle, there is usually only a small effect compared to hydraulic and mechanically induced stresses. Household product mould operate at higher temperature ranges - 500 to 800 °F, which deteriorates faster; this is a historical issue with die-casting moulds.

mechanism were developed, the house product mould maintenance originated from the design department is an unquestionable truth. Moreover, they are in turn reflected in the mode of operation, where configuration and bearing pressure, and the ability of the tool to withstand the responsibilities it assumes.
House product mould designers can invest in some considerations and have a little vision of the possible working conditions that a particular projection design may eventually encounter. Many obstacles to building and operation can be foreseen and prevented by providing simple modifications. It is relatively easy to start in the first phase.
House product mould designers with extensive and up-to-date workshop experience can visualize the entire manufacturing and functional construction method even before transferring any design details to the paper. He will create a purely psychological temporary design outline that depicts all the various parts, their respective functions, the movements between each other, and the way each part is built and produced.

cannot be obtained. Therefore, when an unfolding flag occurs, the first action should be to check if the hydraulic system can be filled at the correct rate and allowed time. If so, and the unfolding mark is still present, check the gate and runner system for any points that may lose pressure and flow during filling and, if desired, make it larger or more direct. The land length of the gate should also be as short as possible.
Gap marks are particularly prone to occur in moldings made of acetal, probably due to their slightly higher melt viscosity. However, as already mentioned, this drawback has been observed when producing small molded articles in many other materials on handheld machines or low power machines. There is little that can improve this molded article, and it must be remembered that their performance may be impaired. Any molding that exhibits a discontinuous surface finish is suspicious and may completely rupture or rupture in an aggressive environment.

, showing an area that is usually close to the door, which has an uneven lining appearance. It may be reminiscent of a groove on a phonograph record, or it may appear to appear as an irregular line pattern, roughly a semicircle around the door.
The reason for unfolding the mark is that the pressurization of the last part of the household product mould is slow. As the back pressure in the household product mould increases, the rate at which the material flows through the gate decreases, and the molten plastic does not have a sufficiently low viscosity to provide good consistency of the mold surface.
In order to overcome this drawback, it is important to quickly fill the mold of the household product at one time. If the machine runs out of power before the filling is complete, the last material can only enter the household product mould at a very slow rate. The pressure in the hydraulic system will gradually increase and will be transferred to the material entering the mold of the household product for further pressurization.

? Due to the many technical requirements of the molded parts to be produced, the type and configuration of mold designs for household products vary widely. Therefore, the classification of mold tool types is usually only applicable. Among all the mold configurations used, the two- and three-plate mold designs are the easiest to identify in appearance. The names of the two- and three-plate designs depend on the number of split or parting lines used in the tool design.
Unmanned mold
More commonly referred to as hot runner molds, where the material supply system remains molten throughout the molding cycle, freezing only at the gate of the molded part prior to discharge from the mold.
Undercut die
The features it produces are characterized by the need for core pull or feature removal to cut the mold cavity or core component prior to opening or ejection of the mold.
Household mould
Many of these different components are manufactured in the same tool, for example, model kits, kitchen appliances, and the like. Household molds are typically used in short-term, relatively low-volume parts to reduce mold costs.
Stacking mold
Stacking molds in which indentations are stacked on either side of the center plate of the mold, typically for vertical molding machines for compression molding purposes, such as manufacturing inserts, recording, sintered molded parts made of PTFE, etc.

depends mainly on the type of plastic, the finish of the colorant and the surface of the household product mould. However, for some other reason, the surface color and gloss defects of the product and the darkness of the surface are often caused. The reasons and solutions are as follows:
(1) The surface finish of the household product mould is poor, the surface of the cavity is rusted, and the mold is poorly exhausted.
(2) The casting system of the household product mould is defective. The cold well should be enlarged, the flow path should be enlarged, the main flow path should be polished, and the sprue and gate should be polished.
(3) The material temperature and the mold temperature are low, and if necessary, a local heating method of the gate can be used.
(4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and darkening of the surface.
(5) The plastic should be completely plasticized, but the material should be prevented from degrading, the heat should be stable, and the cooling should be sufficient, especially thick walls.
(6) Prevent cold material from entering the part and, if necessary, use a self-locking spring or lower the nozzle temperature.
(7) Excessive recycled materials are used, plastic or colorant is of poor quality, mixed with water vapor or other impurities, and the quality of the lubricant used is poor.
(8) The clamping force should be sufficient.

are mainly due to the shrinkage rate of the flow direction in the plastic molding process being larger than the shrinkage ratio in the vertical direction, so that the shrinkage ratio of the parts is different and warpage, which is unavoidable in injection molding. There is a large internal stress inside the part to cause warpage, which is a manifestation of deformation caused by high stress orientation. Therefore, fundamentally, the table mould design determines the warpage tendency of the part. It is difficult to suppress this trend by changing the molding conditions. Finally, the problem must be solved from mold design and improvement.
Melted, silvery, cracked polystyrene, transparent part of plexiglass, and sometimes some sparkling filamentous silver can be seen through the light. These silver stripes are also known as spots or cracks. This is because the stress in the vertical direction of the tensile stress is generated, and the weight of the polymer molecule is represented by the difference in the folding ratio of the reoriented orientation and the unoriented portion.
Under normal circumstances, the gloss of the surface of an injection molded part depends mainly on the type of plastic, the colorant and the surface finish of the mold. However, for some other reason, the surface color and gloss defects of the product and the darkness of the surface are often caused.
Due to the intrusion of the insertion holes, the discontinuous flow rate and the area where the filling flow is interrupted, the molten plastic in the cavity meets in multiple strands, and a linear weld is produced because it cannot be completely fused. In addition, in the case of gate injection molding, a welded joint is formed and the strength at the welded joint is poor.

is not only a cost but also an advantage over traditional lighting. While traditional commercial sign lighting relies on old technology, solar energy continues to evolve and become brighter and more efficient than traditional similar products. An example of this is the use of LED luminaires, which typically use 1/10 of conventional high-pressure sodium or metal halide floodlights and have a longer life. This means brighter logo lighting that makes them stand out in any crowd. In addition, by saving money by first selecting solar energy, business owners can add more markers to increase visibility.
Finally, solar led street lights can be placed in almost any location. Digging into the grid, installing meters, and then purchasing equipment and fixtures may be more expensive than originally purchasing commercial solar lighting systems. Commercial systems have a service life of more than 25 years and require virtually no maintenance. Solar energy is definitely an easy choice.
Affordable, easy to install and maintain, good for the environment, there is no reason not to use solar energy.

is clearly intended to play an important role in the sustainable lighting revolution. Nevada has embarked on an exciting and ambitious new LED streetlight. Together with other energy efficiency projects, this large-scale LED technology conversion will save Nevada's cities and counties more than $300,000 in energy spending over the next few years, in addition to offering benefits such as:
Longer life. LED lamps have a longer life (15 - 20 years compared to 3 - 5 years) compared to older HPS bulbs.
Modern look. The new LED lights present a more modern image.
Improve visibility. Brighter lights mean safer streets.
Thanks to the $1.5 million provided by the American Recovery and Reinvestment Act (ARRA), the Nevada community has recently gained the ability to improve street lighting efficiency and efficiency. The state, all cities and counties implement LED projects, including:
Street light. Now, 4,500 LED road lighting equipment spans the streets of Nevada.
traffic light. Among the various NV counties and cities, the familiar red, yellow and green lights in 1,226 traffic signals now have LED technology.
These attractive, energy-efficient LLED public lighting will undoubtedly contribute to community safety and well-being for years to come.

As the college and university have discovered, installing Led Public lighting(CLASSIC) https://www.classicledlight.com/
bollards, street, path, and four-in-one lighting is just that.
In many schools, a few years ago, LED public lighting began to be indoors, mainly due to a large return on investment. As early as 2008, Boston College noticed that 60% of its energy costs were spent on electricity. They started a plan to improve the lighting efficiency of their dorms, education halls, libraries and parking lots by mixing LEDs and compact fluorescent lights. The school has achieved an annual savings of 58 million kWh and 2,700 metric tons of carbon dioxide and is now re-engineering outdoor architectural lighting and pole lighting with LEDs. BU's Office of Sustainability stated that “the project has produced synergies between environmental awareness and operational efficiency.”
But the advantage of LED public lighting is not just saving energy and money. The improvement in lighting quality is actually surprising. The previous and subsequent images show the changing night scene, the overall is brighter and the shadows are reduced. Streets or plazas that previously provided any number of dark corners and invisible spaces have become reassuring. Because of the hidden options of potential attackers, night walkers returning from the library have better security. If the school has a closed-circuit television system, they can also get a better view.

is that the bulbs run cooler than other bulbs. They don't generate heat, which means they are safer and cooler to touch. Lights that do not generate heat are ideal for landscaping and hanging on or around plants. These types of lamps are manufactured as solid units, so there are no filaments or glasses that can break. They resist shock or vibration, even shock, which means they are more durable than CFL bulbs.
Before buying lighting for the upcoming outdoor entertainment season, consider using LEDs as an alternative to incandescent or standard bulbs. You will do a good job with your wallet and the environment.
The use of LED public lighting in California changed the state. Their history is up to twenty times longer than basic incandescent lighting, and their popularity has increased over the past few years. If you are environmentally conscious, you don't have to hesitate to add these lights to your yard and courtyard. You should be able to buy from any lighting store, home center or do-it-yourself warehouse. It is a good idea to start some research on the web first and understand the products available on the market. In this way, you can enter the store and know exactly what you want or need.

, which has been laying for decades. While some communities are experiencing more and more pain, switching to more energy-efficient, brighter LED public lighting, the color and cost of this conversion is not enough to prevent the replacement of each streetlight with LEDs.
In the past three years, St. George's City has replaced a large number of street lights with LED bulbs, until all the street lights in the city show signs that the LED lights are not decelerating. Many people say they have been able to see the streets better through LED public lighting. Fleming said that LED lights are more energy efficient and brighter than other forms of lights, and because they emit white light, they usually look more like moonlight.
We have encountered many problems with high pressure sodium lamps and associated high maintenance costs. We have to replace many ballasts and luminaires on high-pressure sodium lamps, so we have the ability to turn LEDs.

and the recent changes in computerized paperless offices, people began to pay attention to the impact of office lighting on the human body, and the requirements have also improved. So what is the skill of LED public lighting in office lighting applications?
According to LED manufacturers' surveys, commonly used office lighting fixtures are mainly LED ceiling lamps, LED downlights, LED spotlights and LED panel lights. Ordinary office lighting is about 400-500LX. If you need a better working environment, you can increase the light by 50%. The office is divided into an open office, a cubicle office, a corridor and access area, a reception room, a conference room, and the like. Different office areas have different lighting arrangements.
Open offices are often used in open public areas such as customer service centers and technical offices. As a result, all surfaces are completely evenly illuminated within the illuminated area so that all workstations can be fully illuminated for efficient operation. Lighting should help the employee's physical comfort and produce health, safety, and alertness. The main lighting can use LED public lighting.
In the office, more conversational tasks are usually performed and decisions are made for the company's development. Depending on the lighting requirements, the illumination above the tabletop should be at least 300LX. The lighting in the receiving area should be softer and the lighting should be 200LX better. 3W or 5W LED downlights or LED spotlights can be used. High-power LED public lighting can be installed on the ceiling.
