First of all, tell us about the zinc-aluminum alloy shell. Currently lamps cast zinc aluminum alloy shell thermal conductivity of about 80-90W/MK, together with its subsidiaries oxidation residues, such as electroplating and surface treatment or injection, the actual thermal conductivity is more narrowly, if the cast aluminum alloy AA1070 to LED housing , die casting heatsink is very thick, which resulted in the cooling area is very small, is not conducive to heat dissipation.
Material for aluminum alloy 6063-T5, its excellent heat transfer rate is about 180 - 190W/M.K, heat sink can be made very thin, only 1 mm, thermal structure design unique, maximize heat area, making the products work for a long time under the condition of normal temperature, light body temperature can be kept below 50 ℃, thus effectively reducing bad light led ceiling panel light , but also to ensure that the lighting quality. According to the measured, lamp shell LED the same size, the cooling effect of sunflower radiator is improved more than 1/3 die cast housing.
The appearance of the product according to the modern streamline design, consistent with the public aesthetic concept and creates the perfect classic appearance. In addition, LED sunflower radiator than the casting shell weight 1/3, especially LED lamp volume larger, export, freight can save a lot of!
The advantages of casting is, if it is mass production, die casting production speed is very quick, low cost of production.
