Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dummy lens constructed on the body cover of a retractable headlamp installed in a slant nose type automobile, and in particular to an automobile in which the dummy lens is capable of illuminating the vehicle. This relates to lighting equipment.

[Conventional technology]

In recent years, the body design of automobiles has become increasingly long-nosed and slant-nosed, but it has been pointed out that these automobiles have a problem in which it becomes difficult to confirm the front end of the vehicle body and the width of the vehicle. Therefore, conventional methods include installing so-called fender markers on the left and right upper surfaces of the front end of the vehicle body that can be seen from the driver's seat, or installing fender poles on the front bumper or in the vicinity, so that the location of these parts can be confirmed from the driver's seat. is frequently used. On the other hand, in the case of a slant-nose type vehicle, the headlamp is configured to be retractable, and when not in use, the headlamp is rotated and stored inside the vehicle body, and the outside of the headlamp is covered with a vehicle body cover that is integrated with the design of the vehicle body. Then, the headlamp can be rotated upward together with the vehicle body cover when in use. This vehicle body cover is equipped with a non-illuminating dummy lens that is designed to be integrated with the side clearance lamp when the headlamp is retracted, and a diffuse reflection structure is formed on the back side of the lens, so there is some appearance difference. It was mistakenly thought that a lighting device was attached.

[Problem that the invention attempts to solve]

By the way, with such a slant nose type car body shape, it is not only difficult to install fender markers and fender poles as described above, but especially regarding fender markers,
Due to the outer shape of the vehicle body, it is difficult to choose an appropriate position for the upper part of the vehicle. The method used was used.

Additionally, due to its construction, the dummy lens mentioned above can be confused with other lighting equipment, giving rise to the misunderstanding that it is equipped with an illumination device. Although this was requested by users, there was a problem in that there was not enough space behind the vehicle body cover to accommodate a special lighting device.

The present invention was devised in view of the above-mentioned problems, and it provides a lighting function to a dummy lens configured on the vehicle body cover of a retractable headlamp, and also provides a structure in which this lighting is rotatably fixed on the vehicle body of the vehicle body cover. The purpose of this invention is to propose an automotive lamp that can be used as a fender marker.

[Means for solving problems]

The main feature of the automotive lighting device according to the present invention is that a lighting device formed of a light guide plate is attached to the back side of the vehicle body cover of a retractable headlamp. A diffusion prism is formed on almost the entire back surface of the dummy lens, and a light guide plate having a light diffusion structure such as a hairline or stipple is placed behind the diffusion prism over almost the entire area, and a light source is provided as appropriate in the light guide plate. The light incident on the dummy lens is bent and reflected by the light scattering structure so that the light can be illuminated.

[Effect]

According to the automobile lamp having the above structure, if the light guide plate is illuminated with the retractable head lamp covered, the dummy lens can be illuminated and the lamp can be used as an automobile lamp.
In addition, if the light guide plate is illuminated when the retractable headlamp is rotated upright above the vehicle body, the dummy lens fixed at the viewing height from the driver's seat in the evening and at night can function as a fender marker. It is possible to have both.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle lamp according to the present invention will be described below with reference to the drawings.

Reference numeral 1 in the figure is a retractable headlamp installed on the front of a so-called slant-nose type automobile. The vehicle body cover 2 is provided with a vehicle body cover 2 which rotates together with the retractable headlamp 1 to close the opening B and is designed to be integrated with the outer surface of the vehicle body A when the opening B is closed. Reference numeral 3 denotes a decorative dummy lens made of, for example, smoked clear, which is constructed on the vehicle body cover 2, and has a diffusion prism of an appropriate shape formed on substantially the entire back surface. On the back surface of this dummy lens 3, a light guide plate 4 of a size capable of irradiating substantially the entire surface thereof is arranged. The light guide plate 4 has a light receiving section 4a on its side, and has a light scattering structure 4b such as a hairline or dots on the back side as appropriate, and the light receiving section 4a has a small bulb for a light source supported on the case 5. 6 are arranged facing each other so that the light emitted from the small bulb 6 can be received. When the small bulb 6 is turned on, the light introduced into the light guide plate 4 is bent and reflected by the light scattering structure 4b and shines toward the surface, illuminating the dummy lens 3. .

[Effect of idea]

Since the automotive lighting device according to the present invention is constructed as described above, the decorative dummy lens constructed on the vehicle body cover of the retractable head lamp can be used without forming a special space on the vehicle body side for accommodating the lighting device. The dummy lens can be illuminated by configuring a small and thin illumination device behind it, and the original optical function of the diffusion prism formed on the dummy lens can be effectively utilized to make it decorative as a decorative lens. The present invention has excellent practical effects after implementation, such as improved fashionability and the ability to use the dummy lens as a fender marker when the vehicle body cover is rotated and raised.
