Christmas is getting closer and closer to us. The Christmas tree in front of the mall is decorated with new lights. The LED Light Chain shines today. Ninghai County Yuhua Electronic Appliance Co., Ltd. said that the LED light chain current sampling mode.
1. Voltage: LED lamp bead uses low voltage power supply, the supply voltage is between 2-4V, depending on the product, so it is a safer power supply than the use of high voltage power supply, especially suitable for public places;
2. Current: The brightness becomes brighter with the increase of current. The working current of small power LED lamp bead is 0-60mA, and the working current of high power LED is above 150mA.
3. Performance: Energy consumption is reduced by 80% compared to incandescent lamps with the same efficacy.
4. Applicability: Very small, each unit LED chip is a square of 3-5mm, so it can be prepared into various shapes of devices, and is suitable for a variable... less

The final molding in this production process uses mechanical cold setting, so when the PET bottle is used in the temperature of the PET glass transition temperature of 78 ° C), the molecular chain will be slack and the bottle will be seriously contracted. The bottle is only suitable for cold-filled beverages.
In the process of stretching and shaping of the above process, the hot-filled bottle is always at a relatively high temperature (about 140 °C), and the PET molecular chain is shaped by high temperature in a relaxed state. Finally, the bottle body produces a large number of neat and dense crystals, crystallizing. The degree can reach 30% to 45%, which makes the bottle have higher heat resistance and becomes a practical hot-fill bottle. less

LED Holiday Light today let everyone know about LED Christmas lights: detachable light bulbs and non-removable light bulbs
Anyone who has ever installed a Christmas light will have a problem of dropping a light bulb and causing the entire light bulb to go out. Although the problem of burnout of one bulb causes the entire device to stall, which is no longer a problem, power outages due to the lack of a bulb are still a problem. Unfortunately, even with LED Christmas lights, this is still a recurring problem. Although LED bulb burnout is rare, it is still common for the bulb to loosen in the bulb.
Due to the long lamp life of LEDs, many of the better quality LEDs are now manufactured using integrated bulb and lampholder construction. This prevents the bulb from loosening and falling off, causing the bulb to go out from half to the entire bulb. Another advantage of the one-piece construction is that it... less
