LED lights have the characteristics of high efficiency, environmental protection and long life. However, people who use LED lights will find that because of the high brightness of the LED, it is easy to turn the light energy into heat, making the LED light very hot. At this time, if the LED cannot dissipate heat as quickly as possible, its life span will be greatly reduced.
Many LED manufacturers use aluminum housings for LED lamps. The aluminum casing is easy to dissipate heat, has a beautiful appearance, and is light in weight. Many high-end electronic products use aluminum casings. For example, the company's high-end notebook computer "Mac Pro" series products use all-aluminum shells, which are easy to dissipate heat from the notebook, so that the computer does not even need to install a fan.
The use of aluminum housing for the LED can increase the life of the wick and make the LED light look beautiful. However, aluminum lamp cups are relatively expensive and costly to manufacture, and the lamp cups need to be processed by a lathe. Therefore, some high-quality, medium-quality LED lights will use aluminum lamp housing.
Another common LED lamp housing is a plastic housing. Due to the low cost of plastic shells, some low-end LED lamps will use plastic shells. However, the plastic shell is not easy to dissipate heat, and when the plastic is heated, it is easy to melt and sublimate to produce harmful gases. Therefore, plastic enclosures are not used in Europe, North America, and Japan. Due to the large-volume demand for cheap LED lights in some parts of the country, plastic housings are sold in large quantities in the country.
