Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is characterized in that an ashtray and a cigarette lighter with an illumination ring are arranged side by side in the vehicle width direction, and the light receiving part protrudes rearward from the transparent illumination ring and the rear side of the ashtray. This invention relates to a lighting device for an ashtray and a cigarette lighter, in which a light emitter is disposed at an intermediate position so that light is irradiated toward a light receiving section and an ashtray opening surface.

(Prior Art) Japanese Utility Model Application Publication No. 59-39238 discloses a cigarette lighter lighting device in which a common lamp is used to illuminate the cigarette lighter on the side and the ashtray below. In this case, it is necessary to arrange a dedicated lamp case separately from the cigarette lighter and ashtray. Therefore, a device is also known in which a cigarette lighter and an ashtray are similarly placed side by side in the vehicle width direction, a lamp is placed above the ashtray, and the cigarette lighter is illuminated from diagonally above through an opening. In this case as well, there was a problem in terms of space, and there was also the problem that sufficient ring illumination of the cigarette lighter could not be obtained.

Therefore, a lighting device of the type mentioned at the beginning, as shown in FIG. 5, is well known. That is, center cluster 4
A cigarette lighter 3 and an ashtray 8 attached to a lighter case 2 housed in the perforation are placed side by side in the vehicle width direction, and a lamp 6 is housed in a lamp case 5 attached to the lighter case 2 in the space between them. has been done. As shown in FIG. 5b, an illumination ring 9 integrally formed with a translucent light-receiving portion 9a projecting rearward is arranged around the perforation of the lighter case. Since the lighter case 6 is disposed at a rear intermediate position between the light receiving part 9a and the side surface 8a of the ashtray 8, an opening 5a is formed in the side surface of the lamp case 5 on the ashtray 8 side.
Light is irradiated through the lens 4a on the side surface of the center cluster 4 toward the ashtray opening surface 8c, and directly toward the light receiving section 9a diagonally in front.

[The problem that the idea aims to solve]

However, in this lighting device, when in use, a light leakage area A occurs due to direct light, which is unsightly. There was a problem with light leakage. moreover,
This light leakage does not contribute to illumination of the illumination ring 9 and is wasted.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an ashtray and cigarette lighter illumination device of the type mentioned at the beginning, which efficiently illuminates the cigarette lighter's illumination ring and ashtray opening surface using a common light emitting body.

[Means to solve the problem]

In the present invention, in order to achieve this purpose, the light incident on the front part is reflected from the side of the ashtray 8 side of the light emitter 6 toward the front part at a diagonal position with respect to the vehicle width direction. A louver-shaped polarizing filter 10 is arranged to transmit light incident on the side portion toward the ashtray opening surface 8c.

[Effect]

Polarizing filter 10 from the light emitter 6 to the side part
The incident light falls within the visible angle α with respect to the light emitter 6 and is transmitted as it is to illuminate the ashtray opening surface 8c.

The forward incident light that exceeds the visible angle α is reflected by the polarizing filter 10 and heads toward the light receiving section 8a together with the direct light.

[Example of idea]

1 to 4 show an ashtray and cigarette lighter lighting device according to an embodiment of the present invention.

In this embodiment, the same reference numerals as in FIG. 5 above indicate the same or equivalent parts.

As shown in FIG.
0 is arranged so that the louver direction C coincides with the vehicle width direction (see FIGS. 2 and 3). This type of louvered polarizing filter has the trade name LCF (Light
control filter). The line B connecting the ashtray storage opening edge 4b of the center cluster 4 from the center of the lamp 6 is +22.5° with respect to the louver direction C, and the visible angle α of the louver-shaped polarizing filter 10 with respect to the lamp 6 is: Correspondingly 45° (±
22.5°) is used. FIG. 4 shows the cigarette lighter 3 and ashtray 8 of the louver-shaped polarizing filter 10.
Shows the vertical positional relationship with respect to

In other words, the incident angle range smaller than 45° is set to be the direct irradiation range of the aperture surface 8c, and the -22.5° side with respect to the louver direction C is structurally restricted, so that β shown in the figure is actually the irradiation range. become.

Thereby, the irradiation light within the irradiation range β from the lamp 6 passes through the polarizing filter 10 and the lens 4a, and illuminates the ashtray opening surface 8c. On the other hand, the irradiated light with an incident angle exceeding the visible angle α in front of the lamp 6, that is, closer to the front than the line B, is reflected by the polarizing filter 10, and together with the direct light, the light is received by the light receiving part 9a, in particular, the light directed toward the lamp 6. Head towards surface 9b. Therefore, the light that conventionally leaked through the portion of the lens 4a outside the line B enters the light-receiving surface 9b by reflection, passes through the light-receiving portion 9a, and is illuminated by the illumination ring 9. used.

Incidentally, the scrubbing section 8b is illuminated with indirect light. Further, louver-shaped polarizing filters with various characteristics are used depending on the structural positional relationship and the arrangement angle.

[Effect of idea]

As described above, according to the present invention, by simply arranging the louver-shaped polarizing filter, the incident angle characteristics prevent direct light from leaking from the ashtray, and light leakage from the gap between the side surface of the ashtray and the side surface of the center cluster.
These lights are effectively used to illuminate the lighting ring of the cigarette lighter. Furthermore, since the space between the ashtray and cigarette lighter is used for the lamp case,
This increases flexibility in the size of the ashtray and the surrounding design, and reduces costs.
