Color-adjustable electronic laser pen

Abstract

The invention discloses a color-adjustable electronic laser pen. The laser pen is characterized in that the laser pen is composed of a red laser diode, a green laser diode, a blue laser diode, reflecting mirrors, a laser emitting circuit and a dimming switch, the red laser diode, the green laser diode and the blue laser diode are arranged in a pen shell, and the reflecting mirror, the laser emitting circuit and the dimming switch are arranged corresponding to the red laser diode, the green laser diode and the blue laser diode. The laser emission circuit is composed of three constant current source circuits which are correspondingly connected with the red laser diode, the green laser diode and the blue laser diode respectively. The three reflecting mirrors are light path adjusting devices which are arranged corresponding to the red laser diode, the green laser diode and the blue laser diode respectively, and three paths of lasers of different colors are combined through the reflecting mirror and then emitted out through the aperture on the pen shell. Compared with the prior art, the electronic laser pen is simple in structure and flexible to use, can meet the laser indicating requirements in different use scenes, and achieves clear display under different PPT backgrounds.

Description

technical field [0001] The invention relates to the technical field of electronic pens, in particular to an electronic laser pen capable of adjusting laser color. Background technique [0002] At present, most common laser pointers on the market are monochrome laser pointers with a single color. However, the current PPT background colors are diverse and rich, and a monochromatic laser pointer can no longer meet the needs of clear display under different PPT backgrounds. Therefore, it is necessary to develop a laser pointer that can be adjusted according to the PPT background color to cope with different usage scenarios. [0003] The electronic laser pointer in the prior art has a single color and cannot be adjusted according to the background color of the PPT, which greatly limits the application scenarios of the laser pointer and is very inconvenient to use. At present, there is no report about an electronic laser pointer with adjustable laser color, and similar documents...
