LED heat from aluminum finish, aluminum is exposed to the air, Chinese technology and market recycled aluminum can directly contact with air to form an air convection, the LED can work faster transfer heat generated and distributed into the air. Aluminum alloy material benefits are: to solve the LED heat dissipation, while the production of high product flexibility, how long to cut long, easy to do different kinds of products, but can currently use 20 watts, 30 watts , 40-watt fluorescent lamp bracket compatible. The aluminum profiles can have a variety of cross-sectional geometry. Aluminum profiles can be pulled into a single tube, double tube, the large size of ceiling timber, etc., see-sectional view of an aluminum alloy, Figure 2, Figure 3, aluminum profiles aluminum should be greater than or equal to 80% for the production of aluminum profiles plane finish higher, and plane can not oxidized aluminum profiles cooling strip timber production, is based on the required length cutting, the profile plane evenly coated polymer adhesive material with high thermal conductivity, and then deposited on copper, after pressing together made necessary when used according to the circuit, in accordance with the PCB production process, manufacture aluminum MCPCB, encapsulation of the LED chips are all encapsulated in aluminum PCB, so the chip fixed on the copper foil , the heat generated by the chip work to pass through the copper foil adhesive layer, and then spread to aluminum extrusions, and finally through the air convection heat away. Using this method of production of aluminum tube with good heat dissipation, LED lamp power can be achieved and the power of ordinary fluorescent tubes, like the LED lamp to show their talents in the field of commercial lighting. However, this method of production inputs is high, we should have a dedicated aluminum substrate lamination equipment, invested relatively high initial cost of the product will be higher, after the formation of production capacity, product prices can go back to a reasonable level .

Aluminum PCB can be used to package a variety of colors of the LED chip, you can also install a variety has a good package LED SMD (SMD) to create a red, yellow, green, blue, orange, white, ultraviolet LED lamp, to meet the needs of different industries, including white, warm white LED lamp manufacturing with some difficulty, the most critical issue is the same light color, (using SMD mounted LED lamp color consistency is better, This is because the chip production process has been carried out spectroscopic selection.) which is needed to solve the problem, according to conventional methods: drip phosphor directly on the chip, it can not completely solve the problem of chromatic aberration, we must adopt new technology and new methods solve the problem of chromatic aberration multi-chip package. Effective solution: First, the shade applied directly on the phosphor, the phosphor layer or covering film, we become a common pattern of fluorescent tubes, but we are seeing is a yellow appearance, while the ordinary fluorescent white appearance . Second, the phosphor and transparent plastic raw grain at a certain mixing ratio, by injection molding machines and molds to squeeze out the shade, this method than in the shade on a phosphor coating process easier. White LED lamps produce more white LED chip can be used to encapsulate, white LED chip is a good chip appearance has been coated phosphor, the appearance of the sides and the top of the chip are evenly coated with yellow phosphor, only positive and negative gold, the direct use of Watkins welding on the line, it is more convenient packaging process easier.
