LED tube light housing aluminum and die-cast aluminum car distinction
LED tube light will gradually replace incandescent and even the current ordinary energy-saving lamps, LED tube light in order to solve the heat problem, the basic choice aluminum casing, is now on the market a variety of styles of LED energy saving lamp aluminum shell style after another, but basically that is through the following two processes produced.
The first die-cast aluminum housing
Die-cast aluminum housing LED lamps generally made of zinc alloy, and its conductivity is about 80-90W/MK, many 1-3W small power spotlights basic using this process. Its advantages are low production costs, faster production, but heat dissipation to be worse.
The second CNC lathe aluminum casing short car aluminum
LED tube light car aluminum alloy shell generally choose 6063-T5, the thermal conductivity of about 180-190W/MK, power some of the LED tube light housing are used for this process, the car can be done relatively fine aluminum, thickness and very easy to control so that heat will increase the surface area, enhanced cooling effect, the advantage is significantly better cooling effect on casting, but the production is slow, the cost is much higher than the casting.
