The main materials of indoor led recessed lighting housing are aluminum alloy, stainless steel, and acrylic. The advantages of the acrylic recessed lighting housing are strong color persistence, high surface gloss, bright color; strong light transmission, uniform and soft light emitted; affordable price.
The aluminum alloy recessed lighting housing has good heat dissipation, is not easy to rust, has a beautiful appearance, and is cheaper than other metals.
The advantages of stainless steel recessed lighting housing include its high corrosion resistance and can be use in harsh environments. And it has high-temperature resistance, heat resistance, and even low-temperature resistance. The stainless steel surface is non-porous, easy to clean, beautiful, and is also the preferred material for many practical appliances.
Choose the appropriate processing technology for the indoor led recessed lighting housing according to the material and shape, such as aluminum die-casting and aluminum extrusion lamp radiator, CNC machining aluminum alloy, or not show just the lamp cover. The stamping process does not show just the bracket and so on. The selected materials and processes are different, and the surface treatment methods are also different. Aluminum die-casting recessed lighting housing is suitable for surface treatment methods such as power coated, electroplating, painting, shot blasting, etc., and aluminum extrusion is suitable for surface treatment methods such as oxidation, powder coated, electroplating, and painting.
