Abstract

An illuminating apparatus includes: a light source; and a light guide plate guiding a light of the light source. The light source and the light guide plate are fixed to each other to be receded from a region to which the light is emitted from a light emitting surface of the light source and which is opposite to an emitting surface of the light guide plate.

Claims

1. An illuminating apparatus comprising:

a light source; and

a light guide plate guiding a light of the light source,

wherein the light source and the light guide plate are fixed to each other to be receded from a region which is a light emitting side of a light emitting surface of the light source and which is opposite to an emitting surface of the light guide plate.

2. The illuminating apparatus of claim 1, wherein

the light guide plate is formed with a depression portion for accommodating the light source, and

the light guide plate and the light source are fixed at a boundary between the depression portion and the light source.

3. The illuminating apparatus of claim 1, wherein the boundary between the light guide plate and the light source is sealed with a sealing material.

4. The illuminating apparatus of claim 1, wherein the light guide plate is in contact with a middle point of the light emitting surface in its height direction.

5. The illuminating apparatus of claim 1, wherein the depression portion is an alignment portion to have a shape corresponding to an outer shape of the light source.

6. The illuminating apparatus of claim 5, wherein

the light source includes a plurality of light sources mounted on a substrate, and

the alignment portion has a shape corresponding to the outer shapes of the plurality of light sources.

7. The illuminating apparatus of claim 1, further comprising a reflective material provided in the light source, partially covering the light source, and receded from the region.

8. The illuminating apparatus of claim 7, wherein the reflective material and the light source are sealed with a sealing material.

9. The illuminating apparatus of claim 7, wherein the reflective material covers the light emitting surface, of the light source, on the emitting surface side of the light guide plate.

10. An illuminating apparatus comprising:

a substrate;

a light source mounted on the substrate; and

a light guide plate having a fixing portion and guiding a light emitted from the light source,

wherein the light guide plate allows the light guide portion to face a light emitting surface of the light source at a side to which the light is emitted from the light emitting surface, and

the fixing portion is fixed to the substrate or the light source at a side opposite to the side to which the light is emitted from the light emitting surface.

11. A method for manufacturing an illuminating apparatus, the method comprising:

mounting a light source on a substrate;

fixing a light guide plate to the light source at a side opposite to a light emitting side of a light emitting surface of the light source such that the light emitting surface of the light source faces the light guide plate guiding the light emitted from the light source; and

sealing a boundary between the light guide plate and the light source at a emitting surface side of the light guide plate by use of a sealing material.

12. The method for manufacturing an illuminating apparatus of claim 11, further comprising sealing a boundary between the light guide plate and the light source by means of a sealing material.

13. The method for manufacturing an illuminating apparatus of claim 11, further comprising sealing a reflective material and the light source by means of a sealing material.
