Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grille provided in an automobile, and more particularly to a grille adapted to perform light illumination.

[0002]

[Prior Art]

 In recent years, for the purpose of enhancing the design effect of an automobile, there has been proposed a structure in which a grille provided under a headlight of the automobile is illuminated with light. For example, the front panel of the grill is made of a light-transmissive material, a lamp room is defined inside the grill, and a small light bulb provided in the lamp room is lit to illuminate the front panel. Further, there is also one in which a part of the light of the headlight is guided into the lamp chamber of the grill for illumination.

[0003]

[Problems to be solved by the device]

 In such a grill structure using the former small light bulb, a plurality of light bulbs are required to illuminate the front panel over the entire length, and in addition, the light bulb is not visible from the outside. There is a problem that a diffuser plate is required, power consumption increases, the structure becomes complicated, and the weight becomes high. Also, with the latter configuration, it is difficult to guide light from the left and right sides of the vehicle equipped with headlights toward the center side, and as a result, uneven illumination occurs in which the center part is darker than both sides, There is a problem that the appearance is not good. An object of the present invention is to provide a light illumination grille that enables even illumination without using a light bulb and without complicating the structure.

[0004]

[Means for Solving the Problems]

 The present invention is directed to a grill body disposed adjacent to an automobile lamp, a lens attached to a front opening of the grill body, and a grill body for introducing a part of the light of the lamp into the grill body. It is equipped with a communication window opened in the section and a right-angle film attached to the inner surface of the grill body. To configure.

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 2 is a front view of a vehicle to which the present invention is applied. Headlights 2 and side lights 3 are arranged on the front left and right sides of a vehicle body 1, respectively. A light illumination grill 4 is provided on the lower side over substantially the entire width of the automobile body 1. 1 is an enlarged cross-sectional view taken along the line AA in FIG. 2, and FIG. 3 is a schematic perspective configuration diagram with a part cut away. The headlamp 2 is configured as a so-called prismatic lamp, an inner surface of a lamp body 21 whose upper and lower surfaces are formed flat is configured as a reflecting surface, and a light bulb 22 is supported in the lamp body 21. A lens 23 is attached to the front opening of the lamp body 21.

The light grill 4 is provided adjacent to the lower side of the lamp body 21 of the headlight 2, extends in the vehicle width direction of the automobile, and has a gutter-shaped grill with both ends closed. The body 41 is integrated with the lamp body 21 of the headlight 2. Here, the left and right light illumination grills 4 provided respectively for the left and right headlamps 2 are formed to be half the vehicle width, and both grills are combined to form the entire vehicle width. The front portion of the grill body 41 is opened, and a grill lens 42 colored in a required color is attached to the front portion. Reflective right angle films 5 are attached to the inside upper surface, lower surface and side surface of the grill body 41, and the upper surface of the grill body 41, in other words, the headlamp 2 in this embodiment. A communication window 24 communicating with the inside of the grill body 41 is partially opened on the lower surface of the lamp body 21.

As shown in FIG. 4, the right-angle film 5 has a transparent film 51 made of a thin plate material such as polycarbonate formed on the surface in a stripe shape having a triangular cross section, and on the back surface thereof made of aluminum or the like. Is formed by vapor deposition or the like. Further, a pressure sensitive adhesive 53 can be applied to the back surface of the reflective film 52, and the pressure sensitive adhesive 53 can be used to adhere to the inner surface of the grill body 41. The triangular shape on the surface of the transparent film 51 constitutes a prism 54, and the apex angle thereof is set to a required angle corresponding to the light refractive index of the transparent film 51. In the right angle film 5 as described above, the light emitted at an angle substantially parallel to the surface thereof is reflected at an angle substantially perpendicular to the surface by the action of the prism 54 and the reflection film 52. On the other hand, the light emitted almost perpendicularly to the film surface is reflected at an angle close to parallel to the surface. As such a reflection type right angle film, for example, there is a commercially available product under the trade name of "Solf".

According to the light illumination grill configured as described above, as shown in FIG. 1, the light from the light bulb 22 of the headlamp 2 is reflected by the reflecting surface of the lamp body 21, and is radiated forward through the lens 23. However, a part of the light emitted toward the lower surface of the lamp body is introduced into the grill body 41 through the communication window 24. Then, the surface of the right angle film 5 attached to the inner surface of the grill body 41 is irradiated with the light and reflected there. At this time, as shown in FIG. 3, the right angle film 5 attached to the lower surface of the grill body 41 is irradiated with light from the communication window in a substantially vertical direction. The reflected light is reflected in a direction substantially parallel to the film surface, and is reflected toward the front of the car. If the striped direction of the film is oriented in the front-back direction of the vehicle, the reflected light will be reflected in the vehicle width direction.

Similarly, although not shown, a light angle film attached to the side surface of the grill body 41 can also similarly reflect light in the left-right direction. Further, as shown in FIG. 1, a part of the light emitted to the right angle film 5 on the lower surface is reflected upward according to the law of light reflection, and this light is attached to the upper surface of the grill body 41. It is reflected in the front-rear direction or the vehicle width direction by the right angle film 5. Further, a part of the reflected light is again irradiated to the film on the lower surface, and the same light reflection as described above is performed.

Therefore, the light from the light bulb 22 of the headlight 2 can be radiated to the outside through the lens 42 while being reflected in the full width direction of the light illumination grill 4 due to the unique reflection characteristic of the right angle film 5. As a result, the light illumination grill 4 can be uniformly illuminated over the entire width of the automobile. Moreover, since this light illumination grill does not require a light bulb, a diffuser plate and the like are also unnecessary, and the structure can be simplified and the weight can be reduced. In addition, this light illumination grill utilizes the light emitted downward from the light bulb of the headlamp, but in the case of the square headlight, the light emitted downward in this way is the lamp body. Since it is blocked so that it does not reflect upward in the reflection surface of the headlight, even if a part of such light is used for the lighting grill, the light quantity of the headlight will be reduced. There is no.

[0011]

[Effect of the device]

 As described above, according to the present invention, a part of the light of the lamp is introduced into the grill body, and the light is reflected by the right angle film attached to the inner surface of the grill body to be radiated to the outside. The light-reflecting property of the right-angle film enables uniform lighting, especially in the width direction of an automobile, and simplifies the structure and reduces the weight by eliminating the need for light bulbs and diffusers on the light-grilling grill. There is an effect that can be.
