LED LIGHT SOURCE MECHANISM, TELEPHONE SET, AND METHOD FOR FORMING LED LIGHT SOURCE

摘要

One LED (10) is used as a light source, i.e., an LED light source mechanism (50) that illuminates an illumination surface (11), the illumination surface being laterally long and wide in a left/right direction, in which a central axis of the LED (10) is disposed at a position on a center line vertically extending from a central part in the left-right direction of the illumination surface (11) in such a manner that the LED (10) faces the illumination surface (11), and two reflection surfaces are formed in a conical shape on a reflection surface forming place (12A) so as to surround the illumination surface (11), a light guide part, and the LED (10), and a center line of the conical shape is disposed on the central axis of the LED (10), the two reflection surfaces being configured to reflect light that is emitted from the LED toward an outside of the illumination surface (11). The two reflection surfaces are a first reflection surface (12a) having a conical shape, configured to reflect light from the LED (10) on an outer-surface side thereof, and a second reflection surface (12b) having a truncated-conical shape, the second reflection surface including openings for light on both upper and lower surfaces and configured to reflect light from the LED (10) on an inner-surface side thereof.
