Description

[Detailed description of the invention] [Field of industrial application] This invention illuminates the outer lens periphery with light incident from outside when the light is off, reflecting the vehicle body color or other desired color, and illuminates the outer lens from the center. The present invention relates to a lamp device that is useful as a marker light for vehicles such as automobiles, which is visually recognizable as the shading gradually becomes darker toward the periphery, and has an excellent sense of color unity between the vehicle body and vehicle lamps.

[Conventional technology]

Signal lights such as width lights, turn signal lights, brake lights, and reversing lights installed at the front and rear ends of automobiles have different lighting colors. A predetermined marker color is produced by covering the lens with a colored or uncolored translucent outer lens having a predetermined color filter function.

[The problem that the idea attempts to solve]

However, in conventional vehicle lamp devices, the divisions between the outer lenses constituting each lamp device or the boundary with the vehicle body are clearly defined, and when the lamp device is not lit, the functional Even when not in use, there is a lack of color integration between each outer lens or the vehicle body, and there is a lack of unity as a whole lighting device, especially when a so-called combination type lamp device is configured with multiple marker lights. , which had the problem of being complicated.

The present invention was devised in view of the above-mentioned problems, and when turned on, it is possible to produce a clear lighting color as a marker light, which is required for each lamp device, and when it is not turned on, it is possible to produce a clear lighting color as a marker light. A predetermined color is obtained at the periphery of the lamp device, that is, between the outer lenses of each lamp device or at the boundary with the vehicle body, and the shade of the reflected color is gradually changed from approximately the center of the outer lens to the periphery to make it visible. The object of the present invention is to propose a lamp device that can create a sense of color unity through a so-called blurring effect.

[Means to solve the problem]

In order to achieve the above object, the lamp device according to the present invention includes an outer lens formed of a translucent material, an inner lens formed of a translucent material to be arranged in parallel behind the outer lens, and an inner lens made of a translucent material. a diffusing lens formed of a translucent material to be arranged in parallel behind the lens; a light beam parallelizing means located behind the diffusing lens for irradiating the light beam from the light source as a parallel beam onto the back surface of the diffusing lens; A lamp body is provided with these constituent parts fixedly attached to constitute a lamp device, and at least the peripheral part of the inner lens in the horizontal or vertical direction is curved, and a mirror or semi-transparent surface is formed on the convex surface. A lamp body or outer surface, on which a band-shaped or mesh-shaped reflective film forming a reflective mirror surface is applied in a manner that gradually narrows from the periphery to the center in the curved direction, and the curved portion of the inner lens faces. A measure is taken to form a colored surface of a desired color on the inner surface of the side wall of the lens.

[Effect]

According to the above configuration, when the light is turned on, the outer lens is illuminated with the radiation light from the light source through the gap between the radiation surface of the inner lens and the reflective coating, and the outer lens is colored in a predetermined marker color, and when the light is turned off. Sometimes, external light incident through the outer lens is deflected and reflected to the side of the inner lens by a band-shaped or mesh-shaped reflective film formed on the curved surface of the inner lens, and this reflects to the side of the opposing lamp body or the inner surface of the side wall of the outer lens. The colored surface constructed in the above manner is illuminated to visually recognize the coloring of the vehicle body color or the outer lens or garnish of other adjacent lens devices, as desired, to achieve the above-mentioned blurring effect.

〔Example〕

Embodiments of the lamp device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view showing a first embodiment, in which a lamp device 1 includes a lamp chamber 4 formed by processing and forming the inner surface of a lamp body 2 into a parabolic reflecting mirror surface 3 (a second embodiment described later). and, as in the third embodiment, the structure may be such that the parabolic reflector is housed within the lamp body),
A light source 5 for lighting a bulb or the like is supported and fixed at the focal point F of the parabolic reflecting mirror surface 3, and an outer lens 6 made of a translucent material is provided at the front opening of the lamp chamber 4. Further, the inner lens 7 is arranged in parallel inside the outer lens 6, and furthermore, a diffusion lens 8 is arranged in parallel behind the inner lens 7 to control the irradiation light from the light source 5.

The inner lens 7 arranged as described above is made of an uncolored light-transmitting material, and its surface is curved in a convex shape in the vertical cross-sectional direction, and the inner lens 7 is formed on the curved surface 17a as shown in FIG. The forming width is gradually changed from the periphery to the center in the bending direction,
A band-shaped reflective film 9 having a mirror surface or a semi-transparent mirror surface is applied at a predetermined pitch, and the central part is provided with a radiation surface 17b on which no reflective film 9 is applied, if desired.
The structure is as follows. The above reflective coating 9
can be formed by vapor-depositing a colorless paint containing a metal material, or by pasting a film that has the same effect. Further, the shape of the inner lens 7 itself forming the reflective film 9 may be such that the central portion forming the radiation surface 17b is flat and the peripheral portion thereof is convex. In addition, when the outer lens 6 is configured to be colored in a predetermined color tone, such as a direction indicator light or a brake light, the inner lens 7 is formed of a colored material, or a filter (not shown) formed of a colored material is used. It is possible to have a configuration in which a is attached or interposed.

Note that the curved surface 17a of the inner lens 7 faces the inner surface of the side wall of the outer lens 6 (the inner surface of the lamp body 2).
For example, a colored surface 10 having the same color as the vehicle body color or the outer lens of another adjacent lamp device is formed on the inner surface of the side wall of the
0 is illuminated by the light reflected from the reflective film 9 deposited on the curved surface 17a of the inner lens 7.

According to the above embodiment, when the light is not lit, the light beam L1 that enters the peripheral area of the outer lens 6 from the outside is transmitted to the curved surface 1 of the inner lens 7.
The light is reflected to the side of the inner lens 7 according to the reflectance of the reflective film 9 deposited on the surface 7a and the curvature of the curved surface 17a, and is reflected to the side of the inner lens 7 or the outer lens 6 or the lamp body 2.
When the colored surface 10 formed on the inner side wall of the outer lens 6 is illuminated and viewed from outside the outer lens 6, the surface of the outer lens 6 is colored by the colored surface 10, and corresponds to, for example, the vehicle body or other adjacent lamp device. It is visually recognized by the blurring effect of the color development. In other words, when the light beam L1 is incident from the outside when the light is not lit, the surface of the outer lens 6 is colored from the center to the periphery by the reflective action of the reflective coating 9 of the inner lens 7, and is colored integrally with the outer lens of the vehicle body or the adjacent lamp device. The color develops in a gradually changing color tone. Furthermore, when the light is turned on, the luminous flux L2 emitted from the light source 5 is transmitted through the gap 17 between the reflective coatings 9.
If the reflective film 9 is made of a semi-transparent mirror surface, the outer lens 6 is illuminated through the reflective film 9, and the light acts as a marker light.
