Description

[Detailed description of the invention]

[0001]

The present invention relates to an interior light,
In particular, the present invention relates to improvement of interior lights for vehicles such as automobiles.

[0002]

2. Description of the Related Art Conventionally, so-called direct illuminating lamps, in which a diffuse translucent plate such as an outer lens is disposed in front of a light source, are widely used as vehicle interior lamps.

[0003]

The above-mentioned direct-illumination type interior light may be placed in a narrow cabin, and the light of the super-high-brightness portion of the light source itself is directly illuminated. There are drawbacks. Further, since the light source is disposed near the outer lens, there is also a problem that the lens surface becomes hot.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a vehicle interior light which eliminates glare caused by the presence of a light source and which can obtain substantially uniform surface light emission. Main purpose.

[0005]

A vehicle interior light according to the present invention has a light emitting portion on the front side, a light incident portion on one side, and a diffused inner surface of an enclosing portion excluding the light emitting portion and the light incident portion. A box-shaped body serving as a reflective layer, an outer lens provided at a light emitting portion of the box-shaped body, a light source disposed outside a light incident portion of the box-shaped body, and light of the light source being transmitted from the light incident portion. And a reflector to be introduced into the box-shaped body.

[0006]

In the vehicle interior light according to the present invention , the light of the light source enters the box through the reflector, is reflected by the diffuse reflection layer on the inner surface of the box, and the reflected light passes through the front outer lens. As a result, the light is emitted as uniform surface light.

[0007]

1 to 4 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a rectangular box-shaped body made of a material such as synthetic fat, which is integrally formed with a frame 2 surrounding the outside. The front of the box-shaped body 1 is a light emitting portion 3, and a light incident portion 4 is opened on one side surface of the box. A light source 5 is provided in a frame outside the light incident portion 4. As the light source 5, an incandescent bulb, a discharge tube, an LED, or the like is used.

A diffuse reflection layer 6 is formed on the inner surface of the box-shaped body 1 except for the light emitting portion 3 and the light incident portion 4.
The diffuse reflection layer 6 is formed of a white paint, a white wood, a honing-like metal selective surface, or the like.

An outer lens 7 is provided on the light emitting portion 3 of the box-shaped body 1. A flat fan-shaped reflector 8 is provided between the light incident part 4 and the light source 5 of the box-shaped body 1 to introduce the light of the light source 5 from the light incident part 4 into the box-shaped body 1 as direct light and reflected light. I have. In addition, a light diffusion filter 9 is provided in the light incident section 4.

According to the interior light of the above construction, as shown in FIGS. 3 and 4, light from the light source 5 enters the box-shaped body 1 via the reflector 8, and is formed on the inner surface of the enclosure of the box-shaped body 1. The light reflected by the diffuse reflection layer 6 is further diffused by the outer lens 7, and emitted as uniform surface light. In this case, according to the case in which the light diffusing filter 9 is provided in the light incident portion 4 of the box-shaped body 1, the light incident on the inner surface of the box-shaped body is uniformly diffused. Can be further enhanced.

[0011]

[Effect of the invention] As described above, according to the invention,
The following effects are obtained. (1) A relatively thin configuration is possible. (2) Since the surface light is emitted uniformly, the degree of freedom in designing the outer lens is large. (3) Uniform surface light emission does not cause unpleasant glare. (4) Since the light is indirect light, heat generation on the outer lens surface is small. (5) There is a unique design effect by the uniform surface light emitting source.
