ABSTRACT:
A structure of a diffusing lens for a light emitting diode (LED). The diffusing lens is mounted on, for example, part of the casing of a receiver included in a telephone. A relatively thick plate-like diffusing lens is press fitted in a slot formed in an end portion of the receiver. Implemented by a light transmitting member, the lens transmits light issuing from an LED in a direction perpendicular to the thicknesswise direction thereof while diffusing it in a predetermined direction. Two holes are formed through the lens in the thicknesswise direction, and each receives and retains an LED therein. Two leads extending out from each LED are drawn out from both ends of the associated hole of the lens and connected to a flexible printed circuit board.
