Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an automobile lamp,
In particular, the present invention relates to a lamp suitable for making a lamp for a tail lamp and the like have a high quality feeling.

[0002]

2. Description of the Related Art In a recent lamp for a tail lamp of an automobile, the size of the lamp in the front-rear direction tends to be reduced because it is prioritized to secure a larger volume of a luggage compartment.

[0003]

As described above, in a lamp for a tail lamp of an automobile, the size of the lamp in the front-rear direction tends to be reduced, and as a result, the depth dimension (space) of the lamp housing is suppressed as much as possible. However, when the lamp is viewed from the front side, there is a problem in that it has a feeling of no depth and impairs the sense of quality.

An object of the present invention is to provide a lamp which can give a high-class feeling without giving a pseudo-depth appearance to an actual depth dimension.

[0005]

The object is to provide a container-like housing having an opening formed in the front surface, a reflecting portion formed on at least the rear inner surface of the housing, and a substantially central portion of the rear surface of the housing. In a lamp including a socket provided in a penetrating state and a light source bulb inserted into the socket, at least a visible portion main portion from the opening side of the inner surface of the housing, close to the light source bulb. This is achieved by providing a light-dark portion whose brightness gradually increases from the side toward the opening side.

[0006]

The light-dark portion is configured so that the lightness gradually increases at least in the visible portion main portion of the inner surface of the housing from the housing opening side, from the side close to the light source bulb toward the opening side. As a result, the main portion of the visible portion of the inner surface of the housing from the opening side of the housing with the lamp provided, and the lower inner surface of the housing when the lamp is provided as, for example, a tail lamp of the vehicle, are deeper than the opening. The side becomes dark and the front side looks bright, which increases the apparent depth feeling (front-back stereoscopic effect) in the housing. That is, the appearance of the housing has a feeling of depth in a pseudo manner with respect to the actual depth dimension of the housing, and a high-class feeling can be obtained.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view showing an embodiment of a lamp according to the present invention, and FIG. 2 is a side sectional view of the same. Here, the case where the lamp of the present invention is applied to a lamp for a tail lamp of an automobile will be exemplified.

In FIGS. 1 and 2, 1 is an opening 2
Is a container-shaped housing formed on the front surface, 3 is a reflecting portion formed on at least the rear inner surface of the housing 1, 4 is a socket provided in a substantially central portion of the rear surface of the housing 1 in a penetrating state, and 5 is a socket 4 is a light source bulb inserted and attached. Reference numeral 6 denotes a lens which covers the opening 2, and only a part of the lens is shown. Reference numeral 7 denotes a light-dark portion which is formed on at least the visible portion main portion of the inner surface of the housing 1 from the side of the opening 2 and whose brightness gradually increases from the side close to the light source bulb 5 toward the opening 2 side.

Here, "the opening 2 on the inner surface of the housing 1
The "main part visible from the side" differs depending on the object to which the lamp of the present invention is applied. When the lamp of the present invention is applied to a lamp for a tail lamp of an automobile, the lamp is as shown in FIG. Usually, since it is provided at a position lower than the position of the eye e of a person (general adult), at least the lower inner surface of the housing 1 corresponds to it. When the lamp of the present invention is applied to a lamp provided at a position higher than the position of the human eye e, at least the upper inner surface of the housing 1 corresponds to that.

The term "lightness" means the average lightness at each predetermined position in the front-rear direction of the housing 1, and the light-dark portion 7 is
The average brightness at two light and dark line positions adjacent to each other when formed in the light and dark horizontal stripe pattern illustrated in FIG. 1 is included. It also includes the average brightness at each position in the front-rear direction of the housing 1 when the light-dark portion 7 is formed in a pattern as shown in FIGS. In this case, the average brightness av1, av at each position L1, L2, L3 in the front-rear direction of the housing 1
2 and av3 become larger, that is, brighter toward the opening 2 (front) of the housing 1 (av1 <a
v2 <av3). Further, “gradually increase in brightness” refers to a continuous gradation change (gradation; not shown) without boundaries (blurred boundaries) as a typical example, but not only this but also FIG. 1 and FIG. , Housing 1 even if the boundary has a clear change in shade as shown in Fig. 4.
The average brightness is gradually increased toward the opening 2 side of the. If the pattern is “increased in lightness”, the pattern itself is not limited to that shown in FIGS. 1, 3 and 4, and the shape (quadrangle) of the shaded portion in FIGS. The shape may be another shape, for example, a triangle as shown in FIGS. 5 and 6, or a diamond shape or a circle although not shown. By changing the shape in this way, it is possible to cope with the diversification of the appearance preference. In FIGS. 1 and 3 to 6, the shaded portion indicates a dark portion, for example, a black portion, and the portion sandwiched between the shaded portions indicates a bright portion, for example, a white portion.

The bright and dark portion 7 is formed by sticking a sheet on which painting, plating or painting is applied. Further, the light-dark portion 7 is a resin plate having an uneven surface so that the light and dark can be obtained when the light from the light source bulb 5 is applied, for example, the side closer to the light source bulb 5 is closer to the opening 2 side. A resin plate or the like may be used, which has less reflection and has unevenness such that the reflection toward the opening 2 side increases or increases as it approaches the opening 2. As a method of forming the light and dark portion 7 by plating,
For example, the main part of the visible portion of the housing 1, here the entire area of the lower inner surface of the housing 1, is formed in dark color in advance, and a desired shape, for example, a stripe-shaped mask as shown in FIG. 1 (in the figure, There is a method in which the light-colored portion serves as a mask portion and the light-reflecting film is plated.

Thus, by providing the light-dark portion 7 on the inner surface of the lower side of the housing so that the lightness gradually increases from the side close to the light source bulb 5 toward the opening 2 side, when the light source bulb 5 emits light, the housing thereof is provided. Opening 2 on the lower inner surface
The side is bright and the side of the light source bulb 5 looks dark, and the apparent depth feeling (stereoscopic effect in the front-back direction of the housing) inside the housing is increased, and it is possible to obtain a high-quality feeling with a pseudo depth feeling. . This effect becomes more remarkable by forming the light and dark portion 7 not only on the inner surface of the lower side of the housing but also on the inner surface of the left and right sides.

In the above embodiment, the case where the lamp of the present invention is applied to a lamp for a tail lamp of an automobile has been described, but the invention is not limited to this. When the dimension of the lamp (housing) in the front-rear direction is reduced for some reason, it is not possible to reduce the apparent dimension of the lamp or the dimension of the lamp in the front-rear direction. The present invention can also be applied to a lighting device or the like to be emitted.

[0014]

As described above, according to the present invention, at least the visible portion main portion from the opening side of the inner surface of the housing is gradually increased in brightness from the side close to the light source bulb toward the opening side. Since the formed light and dark portions are provided, the back side of the visible portion main portion is dark and the front side of the visible portion main portion looks dark, and the apparent depth feeling in the housing is increased. Therefore, even if the dimension in the front-rear direction of the housing is small, there is an effect that a pseudo-depth appearance is obtained and a high-class feeling is obtained.
