1. Halogen headlights: The original halogen headlights have the most cars because of low cost. In fact, it is incandescent lamp, the light is yellow, so in some non-sunny tianqi111, the relative penetration ability is relatively strong. However, it also costs more electricity, the lights will slowly dim, and the car will pay attention to it.
2. Hernia headlights: Xenon headlights are filled with inert gases such as xenon and iodide into the quartz glass tube, and then the inert gas is excited by high pressure to release electrons, so that the two electrodes can emit light, the brightness is slightly higher, and the booster is required Immediately increase the voltage of 12 volts to 30.000 volts. However, hernia lamps have poor penetration when rain, snow and fog tianqi111. A lot of cars won't work.
3. LED headlights: LED lights are mainly used as LED light sources. LED is an electroluminescent device that uses solid semiconductor chips as luminescent materials to combine carriers caused by photon emission and direct light emission. LED light source is strong, small in size, not affected by the weather! The service life is night field, and the light source starts faster.
