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, 150w Street Light Housing Wholesale shares the lighting principle of the LED flood light housing.
The aluminum alloy die-casting shell of the flood light housing is painted and tempered, and the glass is made of the same name. The LED is directly connected to the bulb to achieve excellent heat dissipation. The waterproof grade of the lamp body is IP65, which has the properties of corrosion resistance, dustproof, waterproof and shockproof. Professional optical light distribution planning aluminum reflector cup, high light output power, high light utilization rate. It reaches normal brightness within three seconds and has a high color rendering index. There are many colors, such as red, green, blue, yellow and white.
At the current LED lighting technology level, since 80% of the input power is converted into heat, the heat dissipation of the chip is very important. LED heat dissipation information is mainly internal thermal resistance and interface thermal resistance. Use blue LED chips and phosphors to complement each other to obtain white light. Therefore, this type of chip improves the lumen power of the LED, which depends on the initial luminous flux and the light retention rate of the initial LED floodlight housing of the blue LED chip.
First of all, 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 lumen 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 housing of the floodlight, the lamp body is made of high-quality aluminum die-casting, the heat sink and the lamp body are integrated. High-quality thermal grease is used between the integrated light source and the housing to ensure the heat dissipation of high-power LEDs with a low thermal resistance. The constant current drive is separated from the main lamp body, so that the heat dissipation of the integrated light source and the drive are irrelevant. Of course, the encapsulation process is sealed with tempered glass and silicone rubber, and the waterproof and dustproof rating is IP65.
The photoelectric conversion efficiency of high-power LEDs is high, which is 10 times that of traditional incandescent lamps and 2 times that of energy-saving lamps. This is a full manifestation of energy saving features. The heat sinks of high-power LED lamps are mainly based on radiation and convection heat dissipation. By increasing the total effective area of heat dissipation, the heat dissipation performance is improved. The heat sink of the shell is generally made of a material with high thermal conductivity, because aluminum has better heat dissipation than iron, lighter weight than copper and iron, and low cost. Most of the current use of aluminum materials is when choosing LED floodlight shells , Please pay attention to the smooth and clean surface of the radiator. There should be no internal defects. The blackened surface will increase the emissivity, which helps to further reduce the external thermal resistance. Radiator cooling methods can be divided into natural cooling and forced cooling, natural cooling is through natural air convection and radiation. Heat is taken away, and forced cooling is divided into forced air cooling and forced water cooling. Forced air cooling requires a fan, and forced water cooling requires a circulating water system. The housings of high-power LED flood lights used for lighting are all natural air.
