Abstract

A mouse pad having multiple light guide plates including a base, a plurality of light guide plates, a light reflection layer, at least one lateral light source module, a light unifying layer and a pad member is disclosed. The light guide plates are adjacently arranged and linearly extended in the base. The light reflection layer is disposed on a lateral surface of the light guide plates facing the base. The lateral light source module is disposed at one lateral side of the light guide plates. The light unifying layer is disposed on a lateral surface of the light guide plates away from the base. The pad member is disposed on an outer surface of the light unifying layer. The lateral light source module is able to emit lights to the pad member through the light guide plates and the light unifying layer for providing various lighting effects.

Claims

1. A mouse pad having multiple light guide plates, including:

a base, including an accommodation space and an electric wire;

a plurality of light guide plates parallelly and adjacently arranged in a coplanar manner and linearly extended in the accommodation space;

a light reflection layer, disposed between the light guide plates and the base;

at least one lateral light source module, disposed at one lateral side of the light guide plates, and including a flexible wire and a plurality of light emitting units, wherein the flexible wire is electrically connected to the electric wire, and the light emitting units are disposed on the flexible wire and electrically connected to the flexible wire;

a light unifying layer, disposed on top surface of the light guide plates away from the base, and the light unifying layer extending beyond the light guide plates to cover the at least one lateral light source module, wherein the light unifying layer forms as a single piece layer covering the full top surface of the light guide plates; and

a pad member, disposed on an outer surface of the light unifying layer, wherein the light emitting units are able to emit lights to the pad member through the light guide plates and the light unifying layer.

2. The mouse pad having multiple light guide plates according to claim 1, further including a plurality of light shield sheets, and the light shield sheets are disposed between every two of the adjacent light guide plates.

3. The mouse pad having multiple light guide plates according to claim 1, wherein the base includes a bottom plate and a plurality of lateral sheets, and the lateral sheets are served to surround the periphery of the bottom plate thereby defining the accommodation space.

4. The mouse pad having multiple light guide plates according to claim 1, wherein the light reflection layer is directly formed on a lateral surface of the light guide plates facing the base.

5. The mouse pad having multiple light guide plates according to claim 1, further including an anti-skid pad, and the anti-skid pad is disposed between the base and the light reflection layer.

6. The mouse pad having multiple light guide plates according to claim 1, wherein the amount of the light emitting units is corresponding to the amount of the light guide plates.

7. The mouse pad having multiple light guide plates according to claim 1, wherein one side of each light guide plate is formed with a hollow slot, the flexible wire is disposed on a bottom surface defined at one side of each light guide plate, and the light emitting unit is exposed in the hollow slot.

8. The mouse pad having multiple light guide plates according to claim 1, wherein each light guide plate has a plurality of light guide structures.

9. The mouse pad having multiple light guide plates according to claim 1, wherein there are a plurality of lateral light source modules, and two opposite sides of the light guide plate are disposed with one of the lateral light source modules.

10. The mouse pad having multiple light guide plates according to claim 1, wherein the pad member is made of a light-pervious material.
