When we buy an Led light in the market, it is always the Led lights housing(appearance) that we notice first. A beautiful and elegant Led lighting housing attracts great attention of clients, however, the housing plays an important role not just in appearance designing of Led lighting but also in other technical parameters such as light transmission rate, heat sinks etc.
1.The functions of Led lighting housings:
Research data shows a fact: Led lighting’s luminous efficiency will reduce from 20% to 75% with the increase of the lighting temperature from 25 degrees to 100 degrees. So the lifespan of Led lighting depends on so much the environmental temperature of Led lighting. Higher working temperature means a shorter lifespan. How to decrease the lighting temperature to get a long lifespan of LEDs? Of course, we need something for heat sinking. One of the important functions of Led lighting housing is to continuously derive and diffuse the heat generated by LED chips during working to ensure the normal service life of the LED lighting.
2. Main materials applied for Led lighting housings
As explained above, we need a kind of heat conductivity material for making the Led lighting housing to get a nice heat dissipation. Aluminum has been applied in making Led lighting housing for a long time due to its great heat conductivity. People are always trying to find more suitable materials to produce great housings in the lighting industry. Besides aluminum, we can find other housing materials such as iron, glass, ceramic, aluminum alloy, plastic, etc. Let’s see a comparison between 3 main materials of Led lighting housing(Metal(aluminum), plastic and ceramic):
3.Different applications for each housing material
Different materials have been applied in the different Led lightings due to their chemical and physical characteristics.
Metal for Led lighting housings
Aluminum and iron are the most commonly used metal materials for producing Led lighting housing, especially aluminum. As a very popular material, Aluminum has been applied in many kinds of Led lights for a long time. In spite of the great heat conductivity nature, people notice also some disadvantages of aluminum(Metal):
- Different to process and to shape up
- Possible electric shock due to the electric conductivity
- High price
Now the aluminum is applied in high power output Led lights such as Led outdoor lightings and Led commercial lightings. Quark lighting’s office linear lights QK-ll SERIES and quark panel lights use the qualified aluminum housings for a commercial application.
Plastic materials for Led Lighting Housings
The lighting industry is progressing with the fast development of material science. Technicians and scientists are always eager for finding new materials in the Led lighting industry to produce the light, functional and beautiful Led lights. Plastic is obviously a good choice to make Led lighting housing due to its heat conductivity and lightweight. So plastic now is getting more and more popular material in the lighting industry. We apply large plastic material in Led bulbs, spotlight bulbs, Led ceiling lights, Led downlights, Led bulkhead wall lights, Led purification lamp lights etc.
Ceramic for Led lighting housings
As an insulating material with good heat conductivity, ceramic is a good material choice in the Led lighting industry. However, ceramic is easily broken, we apply mostly ceramic in producing small power output Led lightings such as LED bulbs, Led spotlights bulb etc.
