Light emitting apparatus

Abstract

It is a light emitting apparatus having a light source, and also having a light guide element into which light from the light source is guided. The light source is accommodated in an accommodating portion formed a top-surface side of the light emitting element. In the bottom surface of the light guide element, a light emitting portion is formed at a portion which is located away from places directly below the light source and directly below an optical axis of the light source and which extends from a region placed obliquely frontwardly from the light source to a region placed laterally from the light source.

2. The light emitting apparatus according to claim 1, wherein a circuit portion for said light source is also accommodated in said accommodating portion.

3. The light emitting apparatus according to claim 1, wherein said accommodating portion includes a concave portion opened at a side of an end of said light guide element.

4. The light emitting apparatus according to claim 1, wherein said light emitting portion extends in parallel to the optical axis of said light source.

5. The light emitting apparatus according to claim 1, wherein in the bottom surface of said light guide element, said light emitting portion is formed at the portion which is located away from places directly below said light source and directly below under the optical axis of said light source, to continuously extend a region placed obliquely rearwardly from said light source.

6. The light emitting apparatus according to claim 1, wherein said light guide element includes a light diffusion material.

7. The light emitting apparatus according to claim 1, further comprising: a cover, which is configured to cover a top surface side and a lateral surface side of said light guide element and which is made of a material adapted to reflect light outputted from said light source.

8. The light emitting apparatus according to claim 1, further comprising: a cover configured to cover a top surface side and a lateral surface side of said light guide element, and to having a fitting means at a side of an end thereof.

9.
