Patent ID: 7399108

Claim:
A light emitting source, comprising: a reflecting member having an optical axis and a surface for reflecting light and outputting the light forward, a light guiding unit arranged on said reflecting surface of the reflecting member, and light emitting devices for outputting tight to the light guiding unit, wherein the light emitting devices are arranged on an optical axis of the reflecting member, the light guiding unit has a light irradiation surface configured to output to the external the light from the light emitting devices and the light from the light emitting device reflected by the reflecting member, a part of the light irradiation surface of the light guiding unit makes a predetermined angle with the optical axis, and is configured to reflect the light from the light emitting devices, and is configured to form the light into a shape that can be oriented in a direction of the reflecting member, and the reflecting member comprises a backward slope area which is inclined downward in a direction from the light emitting devices toward an outer circumference of the reflecting member that is configured to reflect the light reflected at a part of the light irradiation surface of the light guiding unit in a direction gradually having a larger angle away from the optical axis and orients the light to a periphery of the light guiding unit remote from the optical axis.
