Magotan B7 features

At present, xenon lamps are widely used in mid-to-high-end cars. Because of their high brightness, xenon lamps are equipped with lenses, and the emitted light is very focused, so they are deeply loved by everyone. The color is different from that of ordinary halogen lamps, and the light is white. Xenon lamps are bright, penetrating and not too hot.

These characteristics, such as energy saving, environmental protection, durability and small size, have become the choice of car headlights. But at present, due to the limitation of structure and cost, it can only be applied to some high-end cars. The principle of LED is the PN junction of light-emitting diode. The principle is basically the same as that of xenon headlights. The difference is that there is no need for high-voltage ionization, because the positive and negative ions are directly placed in a fixed space, so it is more stable.
