Advantages of LED lamps:
1. energy saving and environmental protection: the energy consumption of LED lamp is 1/20 of that of halogen lamp
2. low cost and long service life: the service life of the LED lamp can reach 100000 hours, that is to say, basically, your car can't drive and it is still on.
3. high brightness: the brightness is much higher than that of halogen lamp. The warning lamp used as brake lamp has no pressure and strong penetrability.
4. low voltage safety: LED, which is the first electronic component, only needs 12V DC voltage to light up, and there is no need to worry about the voltage of more than 20000 xenon.
5. instant lighting: LED lights can be used at any time, while xenon lights "will be on again later".
6. small size of single LED
LED lamp disadvantages:
1. heat dissipation. Poor heat dissipation will greatly shorten the service life.
2. the power saving performance of low-end LED lamps is still lower than that of energy-saving lamps.
3. high purchase cost.
4. due to the strong directivity of LED light source, special optical characteristics of LED need to be considered in lamp design.
Xenon lamp advantages:
1. it presents blue and white light, which greatly improves the brightness of road signs and signs compared with halogen headlights.
2. compared with halogen headlights, it improves the brightness efficiency by three times, and can provide a clearer driving line of sight at night.
3. halogen headlights consume more than 60W of power, and xenon only needs 35W.
4. xenon has no filament structure and its service life is much longer than that of halogen headlights.
5. in case of failure during use, xenon will not go out instantly, but will gradually darken until it goes out.
Xenon lamp disadvantages:
1. poor spotlight and too bright, it is easy to shake the driver of the opposite vehicle, resulting in accidents.
2. the penetration is too poor. The penetration of xenon headlights is very weak in heavy fog and snow weather.
3. delay effect. Because of the working principle of xenon headlamp, it takes 2-4s to light it.
