The difference between laser headlights and led headlights, what is the effect of laser headlights

The difference between laser headlights and led headlights is that the price is different, andAdapted models are also different. Laser headlights are more expensive, and generally only exist in luxury cars, while LED headlights are relatively low in price and more suitable for models.In addition, the brightness of the two is also different, and the power is the sameUnder the circumstances, the light intensity of the laser headlight is 1.7 times that of the LED, and the laser headlight can be made smaller than the LED headlight.

In addition, the laser headlights and LED headlightsThe principle of light generation is also different.The structure of laser headlights can be roughly divided into four devices: laser light source, reflector, yellow phosphorous filter and reflector bowl. The principle is to rely on the laser diode to emit light, illuminate the reflector, and focus on the yellow phosphorous filter after reflection. The yellow phosphorous absorbs the energy of the laser to produce white light, which is then reflected on the reflecting bowl again, and finally focused to form a white color. The light beam illuminates the road surface. The LED headlights directly provide light energy from light-emitting diodes.

Laser headlights improve the irradiation distance, heat dissipation performance and energy consumption of LED headlights, and have the advantages of fast response speed, low brightness attenuation, small size, low energy consumption, and long life. In addition, the brightness of the laser headlights is currently the highest among the headlights, and it is also more dazzling, and its exposure distance data is 600m. However, the dazzling and distant headlights are not allowed in the country, so the irradiation distance is shortened to 400-500m, but it is still farther than the LED headlights, which is also a difference.
