Ten advantages of automotive LED light sources

1. Good monochromaticity, bright and rich colors. The color saturation reaches 130% full color, which makes the light more clear and soft.

2. Long life and good shock resistance. LED is a semi-conducting element, unlike an incandescent lamp, it has no vulnerable movable parts such as glass or tungsten wire, so it has very low failure and can be repaired.

3. The response time is short, only sixty nanoseconds. It is especially suitable for the light source of automobile lamps and lanterns, and it has won valuable time for drivers to reduce accidents.

4. High efficiency and low energy consumption. The LED light source can produce the red, amber and other colors required by the car lamps without color filtering, without loss, and the power utilization rate is as high as 80%.

5. Small size and light weight. With its characteristics, various lamps that are thin, light, and compact can be designed to provide space for automobile design.

6. Green lighting source. The LED spectrum has good monochromaticity, no extra infrared, ultraviolet and other spectra, no mercury harmful substances, and little heat and radiation.

7. the luminous flux of a single LED is small. At present, the research level of the luminous flux of a single LED can reach 120Im/W, and the product level is less than or equal to 60Im/W. Moreover, high-power LEDs often require large-scale heat sinks. Therefore, LED light sources generally adopt LED array design methods.

8. The plane emits light with strong directionality. It is different from the point light source incandescent lamp. The viewing angle is ≤180°. When designing, it must be noted that the LED light source has a different viewing angle and cannot be greater than 180°.

9. The luminous efficiency of LED decreases with the increase of temperature. Generally, the chip temperature will fail if the temperature exceeds 120℃. Thermal design must be considered in the process design of lamp assembly design and manufacturing.

10. LED is a multi-component compound semiconductor component. The characteristic of the multi-element compound semiconductor element is that its electrical, optical, thermal and mechanical parameters are very discrete. When designing, we must fully consider this feature, and require component production companies to strictly classify and classify components according to the requirements of automotive LED light sources.
