As a new type of solid-state light source, offroad LED light bar has been gradually applied to the interior and exterior of automobile, especially the interior lighting. The application of colorful offroad LED light bar has been mature. However, due to the need for high-power offroad LED light bar, the external headlamp is restricted by technology and cost performance.

What are the kinds of offroad LED light bar?
The offroad LED light bar can be divided into decorative and functional lamps.
Decorative LEDs are mainly used to beautify the inside and outside of the vehicle and show the function of the locomotive. At present, they mostly cooperate with the control circuit to realize colorful transformation. The function light is mainly applicable to the backlight display of the indicator light of the digital instrument assembly, front and rear turn lights, brake indicator lights, clearance lights, reversing lights, fog lights and reading lights. Its use requirements are basically similar to those of commonly used LEDs, but it has high requirements for LED angle, color difference, brightness, voltage discrete value, light attenuation, heat dissipation, ultraviolet-proof and reliability.
In fact, the technology of offroad LED light bar has not only played a decorative role, but also will emerge day by day with its long-life characteristics. It has become the development direction of automotive lighting in the future.
What are the parameters related to offroad LED light bar?
Offroad LED light bar type refers to the angle and shape of the headlights. A good offroad LED light bar marks out the bright and dark areas to help distinguish the road conditions and prevent illuminating the opposite driver’s eyes.
Color temperature is a physical quantity used to define the color of light source in lighting optics. It refers to the color change felt by human eyes under different energy of light wave, which refers to the color of light. This can be seen directly from the parameter box. The bluer the offroad LED light bar color is, the higher the color temperature is. The color temperature is lower if the offroad LED light bar is red. Therefore, it is more appropriate to choose LEDs with color temperature between 4300K and 6000K. It balances brightness and penetration to meet the needs of driving at night and in rainy or foggy weather.
The heat dissipation of the offroad LED light bar determines the service life. After the LED light source is powered on, about 35% of the electric energy is converted into light energy and the rest into heat energy.
How to make offroad LED light bar?
It is necessary to carry out optical design of offroad LED light bar according to the requirements of the standard for light shape, including the selection and design of LED brightness, beam distribution, and beam angle.
Although offroad LED light bar can save energy and has small volume, it has narrow beam angle and high requirements for LED heat dissipation treatment. Therefore, when LEDs are used as lamps, special attention should be paid to the treatment of light.
In addition, if the heat dissipation of offroad LED light bar is not done well, it will not affect the service life but also lead to light attenuation of LED in light-emitting devices.
The quality control and light distribution verification of offroad LED light bar during production are needed. For automotive lamps, compared with headlamps, the requirements of signal lamps are relatively simple. But the main problem is to solve LED uniform light, that is, how to make the output light of LED evenly distributed.
After the offroad LED light bar is made, you need to go to some corresponding institutions for performance test and 3C certification.
