[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of lighting for ashtrays provided in automobile instrument panels and the like.

Therefore, this invention is applicable to an automobile ashtray in which a lighting device such as a lighting bulb is attached to an opening of a protector attached to the upper part of the ashtray box in a lamp housing of a retainer connected to an automobile instrument panel. This invention relates to a lighting device, and in particular, this invention relates to a lighting device for an automobile ashtray in which a convex lens is attached to the lighting device so that the illumination light from the lighting device is focused on the opening of the protector.

<Prior Art> As is well known, a smoking ashtray is placed at a predetermined position inside an automobile so as not to disturb the driver or the like.

Conventionally, for example, as shown in FIG. 1, an ashtray 3 is provided at the lower center of an instrument panel 1 of an automobile, with a smoke-eliminating protector 2 facing toward the front, and an ashtray 3 that can be slid back and forth. In order to confirm the position of the ashtray 3 when smoking while driving at night and to ensure good driving, a lamp housing part 5 of a retainer 4 fixed to the lower part of the instrument panel 1 is provided with a lighting device. A bulb 6 is provided, and when the ashtray 3 is in use and the slide is open, the light beam of the illumination bulb 6 is irradiated into the box part 8 from the opening 7 formed in the protector 2 when the ashtray 3 is in use. A lighting device 9 for an automobile ashtray is used, or an optical fiber (not shown) as a lighting device is provided in the lamp housing portion 5 to emit light.

<Problem to be solved by the invention> However, the light rays generated from the lighting bulb 6, etc., diffuse radially as shown by arrow A in FIG. However, only a small portion of the light rays are irradiated into the box part 8 of the ashtray 3, and most of the light rays are irradiated and reflected from the upper surface of the protector 2 other than the opening 7, which is inconvenient and inefficient. .

A part of the light rays irradiated onto the upper surface of the protector 2 and reflected may leak into the interior of the vehicle, resulting in a disadvantage of energy loss.

As a result, sufficient light is not irradiated into the box part 8 of the ashtray 3, and according to the design, the leaked light may enter the driver's eyes, causing difficulties in driving at night when smoking. .

To deal with this, for example, JP-A-57-18535
As shown in the patent publication, there is a technique in which a concave lens is provided on the retainer 4 to spread the light from the lighting fixture to the box part of the ashtray as much as possible, but the loss of light reflection from the top surface of the protector is There were still problems that could not be avoided.

The purpose of this invention was to solve the above-mentioned problems with the prior art automotive ashtray lighting device, and to prevent the leakage of light beams irradiating the ashtray and to provide a fully functional ashtray that is easy to use both day and night. It is an object of the present invention to provide an excellent lighting device for an automobile ashtray, which can be maintained at a high level and which is beneficial to the field of equipment technology application in the automobile industry.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is based on a retainer fixed to an instrument panel, and a retainer attached to the retainer. The formed recess is a lamp housing, and a lighting device is provided inside the recess to illuminate the inside of the ashtray box when the ashtray is in use, and an opening that covers the top of the ashtray box and corresponds to the lighting device when the ashtray is in use. A convex lens that covers the opening and the concave portion of the protector and is arranged at a position apart from the opening of the protector to focus the illumination light of the lighting device on the opening of the protector. It is designed to be a lighting device for an ashtray.

<Function> A lighting fixture for the opening of the protector provided at the top of the ashtray box is attached to the lamp housing in the recessed part of the retainer connected to the instrument panel, and a convex lens is attached to the underside of the lighting fixture. The light rays from the outside are focused on the opening of the protector, and the focused rays are irradiated into the ashtray box through the opening of the protector, preventing the light from leaking into the passenger compartment from the lighting fixtures and driving safely. Technical measures have been taken to concentrate a sufficient amount of light into the ashtray box so that it does not interfere with the ashtray, and to create a bright illumination state at will, making it possible to smoke comfortably even when driving day and night. This is what I learned.

<Example> Next, an example of this invention will be described below based on the drawing of FIG. Note that the same parts as in FIG. 1 will be explained using the same reference numerals.

Reference numeral 1 designates an instrument panel of an automobile such as a passenger car, in which an ashtray 3 having a box portion 8 at the lower center thereof is provided so as to be slidable back and forth. A smoke extinguishing protector 2 is provided on top, and a light condensing opening 7 with a predetermined diameter is provided at the rear of the protector 2.
is drilled.

When the ashtray 3 is in the sliding open state, the opening 7
A lamp housing portion 5 is integrally formed with a retainer 4 that is connected and fixed to an instrument panel 1 located above the lamp housing.

Thus, the lamp housing portion 5 of the retainer 4
is provided with a lighting bulb 6 as a lighting device,
The peripheral edge of a convex lens 10 is located below the illumination bulb 6 in the lamp housing part 5 and fixed to the lower surface of the retainer 4 by heat caulking, adhesive, etc., so that the light from the illumination bulb 6 is formed in advance so that the focal point of the ashtray 3 is at the center of the opening 7 of the protector 2 when the ashtray 3 is in the open state, forming an illuminating device 9' for an automobile ashtray that forms the gist of this invention. .

Therefore, in this invention, the size of the opening 7 is made as small as possible.

In the above configuration, when the ashtray 3 is slid forward relative to the instrument panel 1 to open the ashtray 3 in order to smoke while driving at night, almost all the light from the lighting bulb 6 is directed to the convex lens 10 as indicated by the arrow F. The light is focused at the center of the opening 7 of the protector 2, and after passing through the opening 7, it is radially diffused and irradiated into the box 8 of the ashtray 3.

Therefore, almost no light rays are reflected on the top surface of the protector 2, light leakage into the vehicle interior is prevented, and all the light rays generated by the lighting bulb 6 are irradiated into the box part 8 of the ashtray 3 as much as possible. This makes it possible to secure a sufficient amount of light, making it possible to more reliably confirm the position of the ashtray 3 at night, etc.
There will be no hindrance to safe driving.

It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment, and various embodiments may be adopted, such as providing a lighting bulb with a portion having the function of a convex lens integrally formed at the bottom inside the lamp housing. It is possible.

<Effects of the invention> As described above, according to this invention, there is provided a lighting device for an automobile ashtray in which a lighting device is attached to an opening of a protector attached to an upper part of an ashtray box in a lamp housing of a retainer connected to an instrument panel. By installing a convex lens on the lighting fixture so that its focus is connected to the opening of the protector, almost all the light rays from the lighting fixture pass through the convex lens without being reflected on the top surface of the protector. Almost all of the light is irradiated within the box of the ashtray, which has the excellent effect of preventing light leakage into the vehicle interior and appropriately illuminating the automobile ashtray with a sufficient amount of light.

As a result, there is an advantage that the position of the ashtray can be reliably confirmed even when driving at night, and safe driving is not hindered.

Further, since the light beam passage opening formed in the protector can also focus the light beam from the illumination device, even a small diameter opening can freely irradiate a wide range depending on how the convex lens is set, which is advantageous.
