Can the laser pointer launch to 10 mile range?
Friends who have used Laser pointer will find that the farther the object is irradiated, the larger the spot area and the darker the color. Laser is a highly collimated light, but it will still gradually diverge as the propagation distance increases and the air is scattered, and the brightness will gradually decrease. Although the moon is extremely far away from the sun (about 400 times the distance between the earth and the moon), the radiant power of the sun to the moon far exceeds that of the laser pointer in our hands. According to calculations, even if everyone in the world is shining at the moon with a laser pointer at the same time, the brightness of the spot is still less than one billionth of the moonlight itself. Although the laser pointer can illuminate to infinity in theory, the actual propagation distance visible to the naked eye is probably only a few hundred kilometers at most. The emission distance of the laser is directly related to the wavelength of the laser, the power of the laser, and the divergence angle of the laser.

The irradiation distance of laser headlights can reach more than 600 meters, which is twice that of LED light sources. The most important thing is that the volume of the laser headlight is much smaller than that of the LED, so that it can provide more possibilities for smart lighting. The irradiation distance of 600 meters is sufficient to ensure that the driver's line of sight is not disturbed, thereby improving driving safety. In this way, the irradiation distance of laser headlights is more than 6 times that of halogen lamps, 4 times that of xenon lamps, and 2 times that of ELD. Such excellent laser headlights are only equipped in high-end luxury cars. Can low-end cars be upgraded with laser headlights? The answer is yes. Yunnan Chebabe Automotive Lighting is the general agent of Hengwei Laser Headlights in Yunnan. The price of upgrading laser headlights is within the acceptable range. The effect of the upgrade is directly as shown in the picture below.
