Background technique

PAR20, PAR30, PAR38 halogen lamps and metal halide lamps, CDM ceramic metal halide lamps are installed in track lights, grille spotlights, embedded ceiling lights, ceiling ceiling lights, wall lights, projection lights and other lamps, which are widely used in Shopping malls, large supermarkets, specialty stores, museums, exhibition halls, etc. are used as key lighting. At present, halogen lamps and metal halide lamps are commonly used as light sources. Halogen light sources have high power consumption, low luminous efficiency, high calorific value, short life, and heavy pollution in the recycling process. Metal halide lamps radiate a large amount of ultraviolet light, take a long time to start up, and cause great pollution in the production and recycling process. The replacement of LED light source modules has long life (50,000 hours), high safety and reliability, low calorific value, high luminous efficiency, low carbon and environmental protection, and can save more than 75% energy than halogen light sources. At present, LED integrated lamps are generally designed to replace traditional lamps in the market, which solves the shortcomings of traditional lamps. It is designed according to the structure and size of traditional lamps, and uses optical lenses to match single or multiple LED light sources, but the disadvantage lies in the existence of light distribution. Ghosting and spots cannot meet the needs of places with high optical requirements, and the lighting parameters of the whole light cannot replace metal halide lamps above 35W and halogen lamps above 75W due to the limitation of structure and driving power. In order to solve the shortcomings of the above-mentioned LED lights, this utility model patent proposes a LED light source module product with novel structure, beautiful appearance, good ventilation and heat dissipation, good optical effect, and higher power, which can well solve the problems of existing LED lights. . the
