Abstract

(57) [Summary] [Purpose] To improve the appearance of the outer lens by allowing the inner lens to stand out through the outer lens of the lamp. In a vehicle lamp including a lamp body 1, a light bulb 3, an inner lens 4, and an outer lens 5, an inner lens 4 attached to the lamp body and a reflection formed on an inner surface of the lamp body 1. On each of the faces 11,
When the diffuser steps 43 and 14 having the same external shape are provided and the lamp is seen through the outer lens 5, the inner lens 4 and the reflecting surface 11 are reflected by the diffuser steps 43 and 14.
(Inner surface of the lamp body 1) is made to appear to be integrated with each other, and deterioration of appearance due to the inner lens being prominently seen is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp having an improved appearance.

[0002]

[Prior art]

 Generally, in order to obtain the required light distribution characteristics, a vehicular lamp is provided with a diffusion step for each of the inner lens and the outer lens attached to the lamp body, and the diffusion step of each of these lenses provides a total light diffusion effect. The light distribution characteristics of On the other hand, the reflective surface formed on the inner surface of the lamp body is formed into a parabolic surface or a spherical surface and functions to reflect light in a desired direction, so the reflective surface itself is formed as a smooth surface. ing.

[0003]

[Problems to be solved by the device]

 In such a lamp, when a transparent lens is used as the outer lens, the inner lens and the reflecting surface are observed from the outside of the lamp through the outer lens, but the reflecting surface is a smooth surface. It looks almost uniform in brightness. However, because the inner lens looks like a stripe from the outside due to the diffusion step provided on the inner lens, the diffusion step of this inner lens becomes more visible than the reflecting surface, and as a result, the inner lens looks conspicuous. Will end up.

In particular, in a turn signal lamp, a transparent lens is often used as the outer lens and an amber lens is used as the inner lens in order to unify the design with the headlamp. From this point, the amber color of the inner lens can be seen as a step through the outer lens, which deteriorates the appearance of the turn signal lamp. An object of the present invention is to provide a vehicular lamp with an improved appearance, in which the inner lens is conspicuously seen.

[0005]

[Means for Solving the Problems]

 The vehicular lamp of the present invention is provided with a diffusion step having the same external shape on each of the inner lens attached to the lamp body and the reflecting surface formed on the inner surface of the lamp body. The inner lens and the reflective surface are constructed so that they can be seen as one piece.

【Example】

 Next, the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of the present invention, in which the present invention is applied to a front turn signal lamp. 1 is a partially exploded perspective view in which a part thereof is broken, FIG. 2 is a front view in which a part of the assembled state is broken, and FIG. 3 is a sectional view taken along line AA of FIG. In these figures, an insulating material such as a resin is molded to form a thin lamp body 1 having a vertical dimension smaller than the lateral dimension. Aluminum is vapor-deposited on the inner surface of the lamp body 1 to form a reflective surface 1. Make up one. Further, the light bulb 3 is supported in the lamp body 1 by using a socket 2 fitted in a hole formed in the back surface of the lamp body 1.

Further, a rectangular cap-shaped inner lens 4 having an amber color is arranged in the lamp body 1 so as to cover the light bulb 3, and a groove 41 formed on the lamp body 1 is provided with an edge 41 on one side. The inner lens 4 is fixed to the lamp body 1 by inserting it into the lamp body 12 and attaching it with the adhesive 7 and fastening the projecting piece 42 provided on the other side portion to the lamp body 1 with the bolt 6. A transparent outer lens 5 is attached to the front opening of the lamp body 1. The outer lens 5 has a sealing leg 51 provided at a peripheral edge portion thereof inserted into a sealing groove 13 provided at a peripheral edge portion of the lamp body 1, and is fixed to the lamp body 1 in a sealed state by an adhesive 7 such as hot melt.

The inner lens 4 has a required prism (not shown) integrally formed on the inner surface of the front surface of the cap, and diffuses the light emitted from the light bulb 3 so that the outline of the light bulb cannot be seen from the outside. To do so. Further, on the outer surface of the front surface of the inner lens 4, a plurality of horizontally extending steps having a cylindrical (cylindrical) cross section are arranged in the up and down direction, whereby the light from the bulb is vertically moved. A vertical diffusion step 43 for diffusion is formed.

Further, the reflecting surface 11 constituted by the inner surface of the lamp body 1 forms a plurality of convex steps extending in the lateral direction at the same time as the shape of the lamp body 1, and the convex step. The vertical diffusion step 14 is formed by evaporating aluminum or the like on the surface of the. In this embodiment, the vertical diffusion step 14 is formed with the same width and pitch as the vertical diffusion step 43 of the inner lens 4. On the other hand, the inner surface of the outer lens 5 is integrally formed with a left and right diffusion step 52 in which a plurality of vertically extending steps having a cylindrical cross section are arranged in the left and right direction.

Therefore, in the lamp having this configuration, the light emitted from the light bulb 3 is diffused in the vertical direction by the vertical diffusion step 43 when passing through the front surface of the inner lens 4. Further, the light transmitted through the side surface of the inner lens 4 is reflected by the reflecting surface 11 of the lamp body 1, but at this time, it is diffused upward and downward by the vertical diffusion step 14 provided on the reflecting surface. Then, when these lights pass through the outer lens 5, they are diffused in the horizontal direction by the horizontal diffusion step 52. This makes it possible to obtain the required light distribution characteristics that are sufficiently diffused vertically and horizontally regardless of the thinning of the lamp.

In this lamp, especially when the lamp is viewed from the front when it is not lit, the inner lens 4 and the inner lens 4 are formed by the same vertical diffusion steps 43 and 14 formed on the inner lens 4 and the reflecting surface 11, respectively. The inner surface of the lighting fixture 1 and the interior of the lighting fixture 1 can now be seen as a single body, and the amber color of the inner lens is not conspicuously visible as in the past, and the appearance of the lamp is improved.

Further, in this embodiment, the left-right diffusion step 52 provided on the outer lens 5 is the left-right diffusion step normally provided on the lens of the headlamp adjacently arranged when the front turn signal lamp is mounted on the vehicle. Since it has almost the same appearance as the step, the design of the front turn signal lamp and the headlamp is unified, which is advantageous in terms of automobile design. Note that the same steps as the front surface may be formed on the side surface of the inner lens 4. Further, when the type and shape of the lamp are different, it is possible to provide the inner lens and the reflecting surface with left and right diffusion steps and the outer lens with up and down diffusion steps.

[Effect of device]

 As described above, according to the present invention, since the inner lens and the reflecting surface are formed with the diffusion steps having the same appearance, the inner lens and the reflecting surface have a completely integrated appearance. Only the lens does not stand out, and the appearance of the lamp can be improved.
