Which is brighter, LED or xenon headlights?
1 Answers
Theoretically, LED headlights are brighter than xenon headlights; in practice, xenon headlights are slightly brighter than LED headlights in most cases. Generally, the brightness of xenon headlights can reach 3200 lumens, while LED headlights can reach 3000 lumens. The specific reasons are as follows: 1. The heat generated by LED headlights during operation needs to be dissipated promptly; otherwise, they will burn out instantly. Due to cost considerations, the power of LED headlights is relatively low. If high-power LED headlights are used, they can be brighter than xenon headlights, but high-power LED headlights are very rare. LED headlights use semiconductor cold light source (cold luminescence, brighter when cooler), with high luminous efficiency and long lifespan, but it is difficult to increase their power. 2. Xenon headlights use high-pressure gas discharge luminescence (thermal luminescence, brighter when hotter), with high luminous efficiency, minimal heat generation, higher power, and longer lifespan. Often, LED headlights appear brighter than xenon headlights because they have a higher color temperature, making them seem very bright. However, this also brings a disadvantage: poor penetration in rainy or foggy weather. Therefore, in practical use, xenon headlights have a wider color temperature range and better performance.
