The floodlight housing is used to illuminate the entire scene, and multiple floodlight housings can be used on site to produce better results. Therefore, in order to better design the lighting when performing outdoor landscape lighting, 50w Street Light Housing Supplier introduces the lighting principle of the LED flood light housing.

The first is that the integrated high-power LED light source is used inside the projection lamp housing, which integrates 8 or 90 solid-state packaged high-power LED chips. The luminous lumens of each chip reaches 80LM. The color rendering index is greater than 80. It can fully meet the lighting standards of outdoor lamps and achieve the purpose of long-term use.

Let’s talk about the project-light lamp housing, the lamp body is made of high-quality aluminum die-casting, and the heat sink is integrated with the lamp body. The high-quality thermal conductive silicone grease is used between the integrated light source and the housing to ensure the heat dissipation of the high-power LED with low thermal resistance. The constant current drive is separated from the main lamp body, so that the heat dissipation and drive of the integrated light source are independent of each other. Of course, the packaging process adopts tempered glass and silicon rubber to seal, and the waterproof and dustproof grade is IP65. The photoelectric conversion efficiency of high-power LEDs is high, 10 times that of traditional incandescent lamps and 2 times that of energy-saving lamps. This is a full manifestation of the energy-saving function.

The heat sink of high-power LED lamps mainly dissipates heat by radiation and convection, and improves the heat dissipation performance by increasing the total effective area of ​​heat dissipation. The heat sink of the shell is generally made of materials with high thermal conductivity, because aluminum has better heat dissipation than iron, lighter than copper and iron, and low cost. Now most of them use aluminum.

Please pay attention to the smooth and clean surface of the radiator when choosing the housing of the LED flood light. There should be no defects inside. The blackened surface will increase the emissivity, which helps to further reduce the external thermal resistance. The cooling method of radiator can be divided into natural cooling and forced cooling. Natural cooling is through natural air convection and radiation. The heat is taken away, and forced cooling is divided into forced air cooling and forced water cooling. Forced air cooling requires a fan, while forced water cooling requires a circulating water system. The shells of high-power LED floodlights used for lighting are all natural air.

Through the above introduction, High Lumen Street Light Housing Manufacturers hopes that you can simply refer to the content of this article in future use.
