1. A solar powered mouse comprising:
- a mouse body;
an optical sensor for generating a cursor control signal by sensing movement of said mouse body;
an internal light source for emitting internal light beams to be received by said optical sensor;
a secondary battery for powering said mouse;
a lens arranged on said mouse body such that external light beams enter an interior of said mouse body through said lens;
a power management device disposed within said mouse body for charging said secondary battery, and comprising;
a solar energy module disposed to receive said internal light beams and said external light beams, so that said internal light beams and said external light beams are converted by said solar energy module into output electricity;
a voltage detector for detecting a voltage level Vs of said output electricity; and
a charging module electrically connected to said voltage detector, wherein said charging module is activated to charge said secondary battery with said output electricity if said voltage level Vs is greater than or equal to a preset voltage value Vth; and
an internal lens to direct a portion of said internal light beams to said solar energy module.

Abstract
The present invention relates to a solar powered mouse. The solar powered mouse includes a mouse body, an optical sensor, an internal light source, a secondary battery, a lens and a power management device. The lens is arranged on the mouse body for focusing the external light beams on a solar energy module of the power management device. The light energy of these light beams can be converted into electricity required for charging the secondary battery of the solar powered mouse.
