Uses and hazards of green laser lights

The technical field of laser lights, in particular, relates to a red, green, blue, and yellow four-color laser light, which includes a lamp body. The lamp body is provided with a control box, a scanning galvanometer, a red laser, a green laser, and a blue laser. The yellow laser, the optical lens group, the scanning galvanometer, the red laser, the green laser, the blue laser, and the yellow laser are respectively electrically connected to the control output end of the control box. There are generally two types of color laser lights used in the market: the first is RGB (red, green, and blue) laser lights. There are three types of lasers: red laser, green Laser pointer, and blue laser. The principle of superposition, three kinds of lasers combined with optical lens group can produce colorful laser; the other is a laser light composed of RGB laser light arbitrarily reduced by one color laser, such as: red and green composed of two lasers: red laser and green laser Yellow three-color laser light, in fact, this kind of laser light is an extension of RGB laser light.
