Components of outdoor laser pointer
The lamp housing includes a lamp housing and a laser, a circuit board and a lower mounting board arranged inside the lamp housing, and a cover body capable of transmitting laser light is provided at the top opening of the lamp housing. The periphery of the lower mounting plate is sealed and connected with the inner wall of the lamp housing, and the laser and the circuit board are located in the cavity between the lower mounting plate and the top of the lamp housing. The bottom of the lamp housing is provided with a vent, the lower mounting plate is provided with a through hole, and the lower mounting plate is provided with a convex ring extending toward the bottom of the lamp housing along the periphery of the through hole. The outdoor laser lamp can realize air circulation between the external air and the entire interior of the lamp housing through the vent and the through hole on the lower mounting plate, and can better realize the rapid cooling of the lamp and ensure its normal operation. In addition, the water that accidentally enters the lamp housing from the vent, because the convex ring provided on the lower mounting plate can effectively prevent it from entering the space where the circuit board is located, avoiding the influence of water on the internal circuit of the laser lamp.

The laser light based on the principle of outdoor Laser pointer light has the advantages of bright colors, high brightness, good directivity, long range, easy control, etc. It looks more magical and dreamy. Used in buildings, parks, squares, theaters, etc., the non-divergence of the laser beam can attract people's attention from a few kilometers away, because the point of laser emission has also become the focus of attention. Laser lights are generally divided into industrial laser lights and entertainment laser lights. The principle of laser lights is to use YAG solid-state lasers, use krypton lamps and Nd: YAG crystal rods to generate laser beams, and form visible green light through frequency conversion. A computer is used to control the galvanometer to produce high-speed deflection to form beautiful characters or graphics.

A computer is used to control the galvanometer to produce high-speed deflection to form beautiful characters or graphics. The principle of laser light is that the ordinary light source emits light in all directions. To allow the emitted light to propagate in one direction, it is necessary to install a certain condensing device for the light source. For example, the headlights and searchlights of automobiles are equipped with condensing mirrors, so that the radiated light is collected and emitted in one direction. The laser light emitted by the laser is naturally emitted in one direction, and the divergence of the beam is extremely small, only about 0.001 radian, which is close to parallel.
