Optical mouse capable of improving spotlight effect

Abstract

The invention relates to an optical mouse for improving the focusing effect, which comprises: a light source, a lens, first reflective surface, second reflective surface, one arc surface, and one optical sensor, wherein the incident light of light source is focused by the lens to be reflected by the first and second reflective surfaces, to be focused by the arc surface, to be projected to one application surface; and the reflected light will be received by optical sensor to control the operation of optical mouse.

Description

Technical field [0001] The invention provides an optical mouse that can improve the light-gathering effect, especially an optical mouse that uses a circular arc surface to improve the light-gathering effect. Background technique [0002] Please refer to FIG. 1, which is a schematic diagram of the internal structure of a known optical mouse 10. The optical mouse 10 includes a light source 11, a convex lens 13, reflective surfaces 12 and 15, a penetrating surface 14 and a light sensor 17. The light source 11 is used to generate light, the convex lens 13 is used to focus the light, and the reflective surfaces 12 and 15 and the penetrating surface 14 are used to guide the light to guide the light generated by the light source 11 to an application surface 19. The light sensor 17 receives the light reflected by the application surface 19 to control the operation of the optical mouse 10. [0003] As shown in the light path in FIG. 1, the light source 11 is used to generate light. The li...

AI Technical Summary

Problems solved by technology

If you encounter an environment with poor light reflection or easy scattering, for example, when working on a glass mat or a table with too bright a surface, because the ambient background light is strong, and the beam area A1 projected to the application surface 19 is relatively large, the optical The intensity of the light received by the mouse 10 is relatively weak. At this time, the optical mouse 10 is likely to misjudge the unevenness of the application surface 19
