Which is brighter, LED or xenon headlights for cars?
1 Answers
Compared to xenon headlights, LED headlights are brighter. Xenon Headlights: Xenon headlights work by filling a quartz glass tube with xenon gas and then using a booster to instantly increase the vehicle's 12-volt power supply to 23,000 volts. Under this high voltage, xenon is ionized, creating a light source between the two electrodes. The advantages of xenon headlights are high brightness, being 4-6 times brighter than the original halogen bulbs. However, they have drawbacks such as extremely high temperatures (300-400 degrees Celsius), which can melt the lamp socket or yellow the headlight cover. They are also very power-consuming, have poor stability, slow startup with delays, and are generally not commonly used nowadays. LED Headlights: LED stands for light-emitting diode, an electronic light-emitting device. It uses a solid-state semiconductor chip as the light-emitting material, where the recombination of charge carriers causes photon emission, resulting in direct light. The advantages of LED headlights include high brightness, being 4-6 times brighter than the original halogen bulbs, and very low temperatures (typically 50-70 degrees Celsius). Due to the low temperature, they are very stable with almost no light decay, instant startup without delay, and provide very uniform road illumination.
