Which is stronger laser headlight or LED headlight
Laser headlights have most of the advantages of LED headlights, such as fast response speed, low brightness attenuation, small size, low energy consumption, and long life. Why does the US law reject laser headlights? Who is the strongest laser headlight or LED headlight? The so-called laser headlights are just auxiliary lights for the high beam of LED headlights? The green laser pointer headlights can illuminate a range of 600 meters ahead in terms of illuminating distance, while models with LED high beams can only illuminate 300 meters. This setting also enables car owners to obtain better safety in sparsely populated areas. Laser headlights hold the trend of the future. Judging from the current actual situation, the biggest disadvantage of laser headlights is that the cost is too high, which is not conducive to popularization.

Lidar is essentially an opto-electromechanical system composed of multiple components. In order to achieve the above functions, commonly used lidars are mainly composed of four parts, namely laser emission, laser reception, scanning and information processing. Among them, optical components are in the top three. There are a large number of parts used, and it is an important part of lidar. As early as 10 years ago, LED entered the automotive field. At present, the application of LED in car interior lighting and brake lights, emergency lights, daytime running lights, etc. has achieved remarkable results. The proportion of lighting sources has exceeded 80%. With the rapid development of LED lighting technology and the gradual decline in cost, LED headlights have been more and more close to the bright prospect of being used in mass-produced vehicle systems after the stages of technical verification and concept car display in recent years.
Since aurora diodes can only emit monochromatic light and cannot directly emit white light, the structure and principle of high power laser pointer headlights are based on the common practice of LED headlights, which are generally a combination of "blue monochromatic light + yellow phosphorous filter". Generate the white light we see. Although the principle of laser headlights is similar to that of LED headlights, under the premise of the same power, the light intensity of laser headlights is 1.7 times that of LEDs, and laser headlights can be made smaller than LED headlights.
