What is the difference between a laser and a lamp?
The laser lamp is equipped with a YAG solid-state laser, which uses a krypton lamp and a Nd:YAG crystal rod to generate a laser beam, and through frequency conversion, a visible green light is formed. Then use the computer to control the galvanometer to produce high-speed deflection, so as to form beautiful characters or graphics. Most people have the impression that if they are irradiated by a laser, the retina of their eyes will be damaged. If a driver of an oncoming car on the road is irradiated by a laser headlight... the consequences are hard to imagine-but this is obviously a misunderstanding Based on the principle of laser headlights, the laser is only the light source excitation medium of the laser headlights, not a direct light source.

The third pain point of laser headlights: the refitting practicality of Laser pointer headlights in the aftermarket. LED headlights in the after-sales market, Huojing Optoelectronics super-concentration LED headlights can achieve lossless replacement of halogen headlights to achieve the high-definition night driving effect of the original LED headlights. To upgrade the laser headlights, it is a complicated process to install laser headlights + LED headlight modules after all. Moreover, the laser performance and irradiation intensity of the laser headlights are even added to the original high-end cars with smart lights to ensure the driving safety on the opposite side of the car. For example, BMW's laser headlights can only be used when their turn-on conditions are set above 40km/h. In addition, the laser headlights will also be turned off when encountering collisions or other extreme conditions.
LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a support, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.
