| 1. An optical mouse light emitter, comprising:
a transparent body;
a divergent light-emitting component, built in said transparent body; and
a pair of pins built in said transparent body and electrically connected to said light emitting component, one of said pair
of pins having a support base formed therein, said support base including a support section and a disc reflective section,
said support section being coupled to a lower edge of said disc reflective section and an upper edge of said disc reflective
section forming an opening, said light-emitting component being disposed on said support section and said disc reflective
section having an internal surface facing said light-emitting component and said opening;
wherein light emitted from said light-emitting component toward said opening of said support base forms a light collection
area, and light emitted from said light-emitting component toward said internal surface of said disc reflective section is
reflected by said internal surface to produce an axial parallel light beam, said axial parallel light beam being collected
in said light collection area.
