The material of the LED lighting profile

1. Aluminum alloy

Aluminum alloy is the most commonly used material in lamp manufacturing.

The aluminum alloy just bought is the form of aluminum ingots, put it into the die-casting machine after pressing out the object, is a common lighting structure, such as the lamp rear radiator lamp body, doughnuts, and directly cast by aluminum alloy lamp body and so on. It has the advantages of light material, high strength and excellent processing, so many lamps will be made of aluminum alloy.

2. Zinc alloy

However, the cost of aluminum alloy is relatively high, there are some material requirements are not very high lamp structure can be replaced with zinc alloy, its mass is slightly heavier, but the cost is relatively cheap. Therefore, the general grade is not particularly high products (used in mid-range lamps), may be zinc alloy as raw materials to do, especially some small parts.

3. Steel plate

Steel is also a very commonly used material in lamps, its wide range of applications, much cheaper than aluminum, plasticity is also very strong, so many need high-strength but do not need high-precision die castings, generally will use steel plate.

4. Plastics

Plastic is just a general term, it includes a lot of kinds, like the usual very common PC, PMMA, it is a class of polymer, the prototype is rice-like gel, as raw materials into the injection molding machine, and then injection molding into the corresponding mold to suppress the suppression of a variety of colors of the face, cover, shell.

Black plastic is often used to do some spare parts in lamps, lids, plates, etc. , and even have the whole lamp is made of plastic (color plastic in the lamp use less).
