Light emitting device
First Claim
1. A light emitting device comprising:
- a mark body;
a substrate, a first surface of which the mark body is arranged;
an LED mounted on a second surface of the substrate; and
a light guide arranged on the second surface of the substrate, including a first surface for introducing a light emitted from the LED, a second surface for emitting a light and a third surface opposing the first surface on which a light is reflected in a diffused manner.

Abstract
The invention provides a light emitting device comprising a mark body, a substrate arranged in back of the mark body, an LED mounted on an opposite surface of the substrate to the mark body, and a light guide arranged on a closer side of the substrate to the LED and having an upper surface serving as a light introducing surface for introducing LED-based light, a side surface serving as a light emitting surface and a backside subjected to a light diffuse reflection process to cause diffuse reflection by the backside. Incidentally, there can be provided a light emitting device comprising a light guide arranged on a closer side of the substrate to the LED and having an upper surface serving as a light introducing surface for introducing LED-based light, a side surface serving as a light emitting surface and a backside having a plurality of protrusions in a rib form.
