Hunan Down Down _ _ Sidon lighting wholesale

Huizhou City Industrial Development Co., Ltd. introduced Sidon LED unidirectional continuity LED is turned on only in one direction (power), called the forward bias (forward bias), when the current flows, electrons and holes in their issued within the composite monochromatic effect is called electroluminescence, and the type of semiconductor material, the wavelength of light, with their use of color and the incorporation of elements related impurities. With high efficiency, long life, unbreakable, high switching speed and high reliability advantages of less traditional sources. White LED luminous efficiency downlights, in recent years has significantly improved, while the purchase price per thousand lumens, but also because the market impact of competing vendors, but decreased significantly. Although more and more people use LED lighting for offices, furniture, decoration, signs and even street use, but technically brand downlight, LED photoelectric conversion efficiency (effective illumination for consumption ratio) is still below the new Wholesale fluorescent downlights, after the development of the national civil whereabouts. Huizhou City Industrial Development Co., Sidon introduce LED lights and LED curing process refers to the package after curing epoxy curing curing epoxy curing conditions generally 135 ℃, 1 hour. Molded package generally at 150 ℃, 4 minutes. After curing is to allow the epoxy to fully cure, while the LED heat aging. After curing the epoxy is very important for improving the bracket (PCB) of the adhesive strength. General conditions for 120 ℃ downlight factory, four hours. LED cut tendons and dicing the LED is linked (not individual) in production, Lamp LED package by cutting off tendons connect muscle LED bracket. SMD-LED is on a PCB board, you need to separate the dicing machine to complete the work. Optical parametric test LED LED test, the test dimensions, while sorting LED products according to customer requirements.
