Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention improves decorativeness and functionality by illuminating a decorative lens formed on the front or rear grille or side surface of an automobile from the back side. The present invention relates to a decorative lens lighting device.

[Conventional technology]

Conventionally, in automobiles whose front grille has been formed into a so-called slant nose type, the headlamps are retractable, and when the headlamps are not in use, they are stored on the outside of the vehicle body, which is designed to match the lenses of the side clearance lamps. An integrated dummy lens can be attached, and even for cars with a general body shape, decorative lenses can be attached to the front or rear grille, areas other than where vehicle lights such as head lamps and rear lamps are attached, and the sides of the car body. There was one with a lens attached to it.

[Problem that the invention seeks to solve]

However, the above-mentioned dummy lenses and decorative lenses (hereinafter referred to as "decorative lenses") are simply installed for the purpose of decorating the vehicle body.
Many of them are non-illuminating by nature, and their decorative effect is small in the evening and at night, even during the day. Therefore,
Some of these decorative lenses are equipped with a reflector behind them in order to reflect the irradiated light from other vehicles or nearby light sources, but with this configuration, the reflector housing section is configured. Therefore, not only is it necessary to provide an extra depth space on the vehicle body side, but also the decorative lens itself becomes large.

The present invention was devised in view of the above problem, and by arranging a small and thin lighting device behind the decorative lens, there is no need to construct an extra storage space on the vehicle body side. It is an object of the present invention to propose a decorative lens lighting device that enhances the decorative effect by using a self-luminous lighting device in which the color of the emitted light can be arbitrarily selected.

[Means for solving problems]

In order to achieve the above object, the decorative lens lighting device according to the present invention is configured with a retractable cover on the vehicle body side, and includes a filter lens formed with a diffuser lens on the back surface, and an inner lens in the case opening. and a lighting device that accommodates a light source in the light receiving part of a light guide plate placed behind the inner lens, and the inner lens on the lighting device side is attached to the rear surface of the filter lens on the vehicle body side. The gist is that the light transmitting portion is arranged so as to be detachable from the formed light transmitting portion.

Further, a prism having light diffusivity or directivity can be formed on the back surface of the filter lens or the front or back surface of the inner lens.

[Effect]

The decorative lens lighting device having the above structure guides the light emitted from the light source into the light guide plate, and the light guide plate illuminates the filter lens configured on the vehicle body side from behind through the inner lens. The prism formed on the filter lens or inner lens can diffuse the light emitted from the filter lens or give it directivity in a predetermined direction, and depending on the component part of the decorative lens, it can also function as a fender marker. It is also possible to have

This filter lens 1 is installed as a so-called dummy lens on the outer surface of the vehicle body side cover 2 of a retractable headlamp configured in a slant nose type automobile, for example, and has a diffuser lens 1a formed on the back side and a diffuser lens 1a on the front side or A light transmitting portion 1b is provided on a partial surface. 3
is a lighting device placed behind this light transmitting part 1a, and a case 4 forming an outer casing of the lighting device 3.
The light transmitting portion 1b is opposite to the light transmitting portion 1b, and the light transmitting portion 1
Opening 4 with a size approximately comparable to the width of b
An inner lens 5 is fitted to the inner lens 5, and a light guide plate 6 is arranged on the back side of the inner lens 5. The light guide plate 6 is provided with a light receiving section 6a on the side thereof, and has a light scattering structure 6b such as a hairline or dots on the back side as appropriate. are arranged facing each other. The light beam incident on the light guide plate 6 due to the lighting of the small bulb 7 is bent and reflected toward the surface side at the light scattering structure 6b.

8 is a prism engraved on the surface side of the inner lens 5 as desired. This prism 8 imparts light diffusing properties or directivity to the inner lens 5, and can also be configured on the back side of the inner lens 5 as appropriate. FIG. 4 shows an example in which a prism 8 having light diffusing properties is configured, and diffused light (arrow A) is emitted from the outer surface of the filter lens 1. In addition, FIGS. 5A and 5B show a prism 8 having light directivity in a predetermined direction.
The light reflected at the light scattering structure 6b portion of the light guide plate 6 and emitted to the inner lens 5 side is bent and reflected in a predetermined direction (arrow B) at the prism 8 portion. Therefore, for example, the illumination device 3 provided with the prism 8 as described above is placed over the housing part b of a retractable headlamp as shown in FIG. If the structure is combined with the decorative lens 1 configured on the vehicle body cover 2 to be used, the light flux emitted from the decorative lens 1 can be corrected and controlled in the direction of the driver's seat. It becomes possible to use it as a fender marker. It goes without saying that the above correction control method can be freely modified by changing the step configuration of the prism 8.

As shown in FIG. 6A, this prism 8 is further configured with, for example, a metal reflective vapor deposition layer 9 on the outer surface of the reflective surface 8a of the prism 8, thereby efficiently and reliably achieving a reflective effect in a predetermined direction. This also has the effect of improving the appearance of the outer surface of the prism 8 from the direction of arrow C.

In addition, non-parallel lines as shown in Figure 6 (b) are also reflected in the direction of arrow D by this reflective vapor deposition layer 9, so that when the retractable headlamp is not used (see Figure 6 (c)). It is also possible to irradiate the front side of a car, which is useful for improving decorativeness and fashionability as a decorative lens.

Furthermore, FIG. 7 shows a means for colorizing the light emitted from the inner lens 5, in which the inner lens 5 itself is formed of a milky white or light smoke colored material, and the outer surface of the reflective surface 8a is formed with a color. A colored paint layer 10 such as amber color is further applied on the outside of the reflective vapor deposited layer, and a filter 11 of red color etc. is formed on the small bulb 7. According to such a configuration, the attachment part of the illumination device 3 is visually recognized as an amber color when the lighting device 3 is not lit, but red emitted light is obtained when the lighting device 3 is lit, which further enhances the decorativeness and fashionability of the decorative lens 1. can be increased.

It goes without saying that the colored material of the inner lens 5, the colored type of the coating layer of the prism 8, the filter color of the small bulb 7, etc. can be freely selected and changed by combining them. be.

Note that the decorative lens lighting device according to the present invention is not necessarily limited to mounting the retractable headlamp on the vehicle body cover 2, but has a structure fixed to the vehicle body side, or a structure that moves up and down with respect to the vehicle body. It goes without saying that modifications can be made to the vehicle body cover that covers all or part of the headlamp.

〔Effect of the invention〕

Since the decorative lens lighting device according to the present invention is constructed as described above, not only is there no need to form a special space for accommodating the lighting device on the vehicle body side, but also a predetermined space is provided in advance on the decorative lens side. If a light transmitting part is formed, it is possible to attach and use a lighting device as appropriate, change the emitted light color, and replace one lighting device configured separately as an accessory with another lighting device. After implementation of the present invention, it is possible to improve the decorativeness and fashionability of the decorative lens, and furthermore, it can also be used as a fender marker for a slant nose type automobile that constitutes a retractable headlamp.
