Abstract

A lighting device for use in vehicles includes a light generating part having a substrate and a light source disposed on the substrate; a base including a light emitting part having a light emitting surface for emitting light from the light source, and a reverse surface on a backside of the light emitting surface, and a connector housing part disposed on the reverse surface and housing a connector electrically connected to the light source; and a case assembled with the base and housing the light generating part and the connector housing part. The base including the light emitting part and the connector housing part is an integral molding and constituted by a light transmitting member containing a light diffusing material.

Claims

1. A lighting device, comprising

a light generating part having a substrate and a light source disposed on the substrate;

a base including a light emitting part having a light emitting surface for emitting light from the light source, and a reverse surface on a backside of the light emitting surface, and a connector housing part disposed on the reverse surface and housing a connector electrically connected to the light source; and

a case assembled with the base and housing the light generating part and the connector housing part,

the base including the light emitting part and the connector housing part being an integral molding and comprising a light transmitting member containing a light diffusing material.

2. The lighting device according to claim 1, wherein at least part of the connector housing part is located in an optical path of light emitted from the light source.

3. The lighting device according to claim 1, wherein the substrate has a light-source-disposed surface on which the light source is disposed, and

at least part of the connector housing part is located between the light-source-disposed surface and the reverse surface of the light emitting part in the case.

4. The lighting device according to claim 1, wherein at least part of the connector housing part is located within a light distribution angle of light from the light source.

5. The lighting device according to claim 1, wherein the light emitting surface has a luminous surface for emitting light to reach a lighting target area of the lighting device,

at least part of the connector housing part is located between a backside surface of the luminous surface and the light source in the case.
