1. Affected by temperature
LED light luminous efficiency and temperature is inversely proportional to the higher the temperature, the lower the luminous efficiency, and more than 120 ℃ will fail. In the lamp assembly design and manufacturing process design, we must consider the thermal design.
2. Environmental protection
LED lights shock, drop, waterproof, can be recycled after recycling, no pollution. So the combination, small size, it is easy to be developed in small lighting products, easy to install and maintain.
3. Good quality, long life
LED majority of the use of PC, silicone and so do the shell, not with the traditional glass and tungsten, so no maintenance. Small size, light weight, not easy to break.
Another advantage, LED half-life is about 2-9 million hours, the service life of up to 7 years, significant cost savings, but also eliminates the trouble of frequent lights.
4. Belonging to the green lighting source
LED in the run-time can be assured that touch, because it is low heat, no heat radiation, are cold light source. Can accurately control the direction of lighting, reducing light pollution, the appropriate adjustment of light angle, to achieve a combination of light and art.
5, LED attributes
LED is a multi-compound semiconductor devices, which is characterized by electrical, optical, thermal and mechanical parameters such as the dispersion of a large index. If there is a special light source requirements, the classification of the device to make a strict control.
6. Large luminous flux
After several decades of evolution, LED light effect has been a qualitative improvement. Incandescent, fluorescent, sodium light efficiency of 12-1400 m / W, and there is a great loss. As countries attach importance to LED development, so its single level can reach 120lm / w, in order to allow LED to install a large radiator, LED light source is generally used in the design of the column.
7. The reaction is fast
1s for the people sometimes have to keep up with the senses, and less than 65ns, is the LED light response time, and can operate in high-frequency, so the use of the automotive industry, race against time for the world to fight for the time to reduce the accident.
