Abstract

A lighting module and an illuminant mouse pad are disclosed. The lighting module includes a plurality of point light sources and a light guide plate; the light guide plate includes a light-emitting section, a light incident section, and a light-reflecting section, the light-reflecting section is connected to the light-emitting section and the light incident section and has a light-reflecting surface; light beams from the point light sources are incident to the light guide plate through the light incident section and emitted out from a light-emitting surface of the light-emitting section after the light beams are conveyed by the light-reflecting surface. The illuminant mouse pad includes the lighting module abovementioned, a base, and a mat; the base includes a receiving part for accommodating the lighting module, and the mat partially covers the lighting module and exposes the light-emitting surface.

Claims

1. A lighting module, comprising:

a plurality of point light sources; and

a light guide plate having a light-emitting section, a light incident section, and a light-reflecting section, wherein the light-reflecting section is connected to the light-emitting section and the light incident section and comprises a light-reflecting surface, light beams from the point light sources are incident to the light guide plate through the light incident section and emitted out from a light-emitting surface of the light-emitting section after the light beams are conveyed by the light-reflecting surface.

2. The lighting module of claim 1, wherein an included angle between the light-reflecting surface and a lower surface of the light incident section is 45±

5 degrees.

3. The lighting module of claim 2, wherein the light incident section includes a plurality light incident surfaces, the point light sources are disposed adjacent to the light incident surfaces, and a normal line of each light incident surfaces is disposed in respective orientation perpendicular to a normal line of the light-emitting surface.

4. The lighting module of claim 3, wherein the light incident surfaces comprise a plurality of microstructures.

5. The lighting module of claim 3, wherein the light incident section further comprises a plurality of perforated portions, the point light sources are disposed within the perforated portions, and a sidewall of each perforated portion is the light incident surface.

6. The lighting module of claim 5, wherein the perforated portions are arranged in an annular shape on a center of the light incident section.

7. The lighting module of claim 6, wherein the light incident section further comprises a plurality of slots, and each slot is disposed between two adjacent perforated portions.

8. The lighting module of claim 7, wherein lengths of the slots are increased when distances between the light incident surface and the light-emitting section increases.

9. The lighting module of claim 1, wherein at least one of the light-emitting surface and the light-reflecting surface comprising a textured structure.

10. The lighting module of claim 1, wherein the light-reflecting section further comprises a light-deflecting surface facing the light-emitting surface, the light-reflecting surface faces the light incident surface, light beams from the point light sources are incident to the light incident section and emitted out from the light-emitting surface after light beams are conveyed by the light-reflecting surface and the light-deflecting surface accordingly.

11. The lighting module of claim 10, wherein a texture structure is formed on the light-deflecting surface.

12. An illuminant mouse pad, comprising:

a base comprising a receiving part;

a lighting module, disposed in the receiving part and comprising;

a plurality of point light sources; and
