Is the shell of the LED lamp a good die-cast aluminum shell or a car aluminum shell?

The aluminum shell of the die-cast LED energy-saving lamp is generally made of zinc-aluminum alloy, and its conductivity is about 80-90W/M.K. Many low-power spotlights of 1-3W basically use this process. The advantage is that the production cost is low, the production speed is fast, but the heat dissipation is worse；

The aluminum casing of LED energy-saving lamps generally chooses aluminum alloy 6063-T5, and its thermal conductivity is about 180-190W/M.K. The casings of LED energy-saving lamps with higher power use this process. The aluminum can be made more exquisite, and the thickness is easy to control. , In this way, the surface area of heat dissipation will increase, and the heat dissipation effect will be enhanced. The heat dissipation effect is obviously better than that of die casting, but the production speed is slow and the cost is much higher than that of die casting.

Car aluminum is an aluminum profile, and the material is processed by a lathe; die-casting aluminum is to melt solid aluminum into aluminum water, and then die-cast through a mold (that is, molding).

Below, Dongguan Zhigao will give you a detailed introduction to the characteristics and differences between die-casting aluminum and automotive aluminum processes.

The first type of die-casting aluminum LED lamp cup die-casting aluminum shell is generally made of zinc-aluminum alloy, and its conductivity is about 80-90W/M.K. Most of the low-power spotlights basically use this process.

Its advantages are: low production cost, fast production speed, but poor heat dissipation.

The second type of aluminum casing processed by CNC lathes, abbreviated as car aluminum, generally choose aluminum alloy 6063-T5, 180—190W/M.K, the LED lamp cup shells with higher power use this process. The aluminum can be more beautiful, and the thickness is easy to control, so that the surface area of heat dissipation will be increased, and the heat dissipation effect will be enhanced. The advantage of the heat dissipation effect is obvious. Better than die-casting aluminum LED light cups, but the production speed is slow and the cost is much higher than that of die-casting aluminum housings.
