Background technique

As the fourth-generation lighting source, LED has the advantages of high luminous efficiency, no ultraviolet and infrared light pollution, no heavy metal element pollution, long life, etc., and is widely used in various lighting fields. Flood lights generally have relatively high power and are widely used in stadium lighting, performance lighting, building exterior wall lighting, billboard lighting and other places. Using LED lamp beads instead of traditional light sources in flood lights can effectively use LED energy saving The advantages of environmental protection.

However, since the LED itself is a Lambertian light source, the distribution of light intensity is not uniform, and directly used as a floodlight will form a lighting effect with a bright center and dark surroundings. Secondary optical light distribution design is required to meet specific lighting requirements. At the same time, floodlights are mostly used for outdoor lighting. Exposure to the outdoors for a long time will be affected by dust and water vapor, and even damage the lamps in severe cases. At present, floodlights generally adopt two methods of waterproof and dustproof: one is the glue type, which is filled with sealant or glass glue at the joints and outlet holes of the lamps, which can obtain better waterproof and dustproof effects. However, there are strong ultraviolet radiation and temperature change impact outdoors, the glue is easy to deteriorate and the waterproof and dustproof performance is reduced, and the glue also has environmental pollution, inconvenient maintenance, and difficult to recycle. The other is to use the sealing ring pushed into the bead for waterproof and dustproof, and the sealing effect is good. However, the power of the floodlight is high, and the LED lamp beads will generate more heat when it is lit, causing the air inside the lamp to expand and contract with heat and cold, and it is easy to squeeze the sealing ring and cause deformation, thereby affecting the waterproof and dustproof effect.

2. Placing a lens plate on the LED array can perform secondary optical light distribution treatment for each LED lamp bead to meet specific lighting requirements.

3. A waterproof joint is installed on the lamp housing, and the glass plate is pressed tightly in the frame with a glass pressure plate. The sealing ring provided between the panel and the lamp housing can effectively improve the waterproof and dustproof ability of the floodlight. The respirator can only Through the air and isolating water vapor and dust, the air in the lamp housing can flow in and out smoothly due to thermal expansion and contraction when the floodlight is powered on and off, reducing the deformation of the sealing ring caused by the pressure difference inside and outside the lamp housing.
