Patent ID: 7046906

Claim:
A light guide pillar disposed on a circuit board of an electronic apparatus for guiding light source emitted from a light emitting element disposed on the circuit board to outside of the electronic apparatus, the light guide pillar comprising: a bulk that is opaque and is disposed on the circuit board, the bulk covering the light emitting element on the circuit board; and a pillar disposed on the bulk, one end of the pillar being inserted into the bulk, an other end of the pillar being extended outside of the electronic apparatus; wherein the bulk further comprises: a concave groove formed on the bottom surface of the bulk for containing therein the light emitting element on the circuit board, the top surface of the light emitting element and the bottom portion of the concave groove forming a gap therebetween; an insertion hole defined in the bulk, one end of the insertion hole being formed on the bottom portion of the concave groove corresponding to the position of the light emitting element, an other end of the insertion hole being formed on the top surface of the bulk, whereby the insertion hole is adapted to receive one end of the pillar inserted therein; and wherein the pillar further comprises: an insertion portion, which is formed on one end of the pillar, and is inserted in the bulk, the insertion portion being substantially smaller than the pillar, the insertion portion and the top surface of the light emitting element forming a gap therebetween; and a viewable region formed at an other end of the pillar, the viewable region being extended outside of a hole formed on the electronic apparatus.
