Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an automobile room lamp, and more specifically to an automobile room lamp in which a lamp unit is attached to the side rail garnish of the automobile. . Note that the side rail garnish section of an automobile refers to an interior material applied to the inside of a pillar formed at the center of the side of the vehicle body.

<Prior art> As shown in Fig. 5, in the conventional interior lamp for an automobile, the lamp unit 2 is simply attached to the side rail garnish section 1 of the automobile, so that the light emitted from the lamp unit is There was a problem where the light directly entered the eyes of passengers, causing glare.

<Problems to be solved by the invention> The present invention was devised in view of these conventional problems, and at the same time eliminates the risk of the light from the lamp unit directly entering the eyes of passengers. The purpose of the present invention is to provide a room lamp for an automobile that can gently illuminate a wide area.

<Means for Solving the Problems> The interior lamp for an automobile of the present invention which achieves the above object has a lamp mounting portion with an upwardly facing irradiation window formed in a bulging portion in the side rail garnish portion of the automobile, and It is characterized by a lamp unit installed inside the mounting part.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a side rail garnish section of an automobile, and a lamp mounting section 3 is formed in a bulge on the inside of the vehicle of this side rail garnish section 1, and a lamp unit 2 is installed inside the lamp mounting section 3. In addition, 4 in the figure
5 is the vehicle roof, and 5 is the interior roof.

The lamp mounting part 3 is molded into the same body as the side rail garnish part 1 or separately, and is formed to protrude into the inside of the vehicle in a bulging shape, and the upper part of the lamp mounting part 3 is provided with a light beam that irradiates upward (toward the interior roof 5). The window 3a is formed as an opening.

The lamp unit 2 basically consists of a light source bulb 2a and a lens 2b, and is housed and installed inside the lamp mounting section 3 of the side rail garnish section 1, and the light from the light source bulb 2a is passed through the lens 2b and sent to the lamp mounting section 3. The light is irradiated from the irradiation window 3a toward the indoor roof 5. The lens 2b of the lamp unit 2 is installed inside the irradiation window 3a of the lamp mounting part 3 so that it cannot be seen from inside the car, and it is also equipped with a refraction system or a refraction system so that the light from the light source bulb 2a reaches near the center of the interior roof 5. A lens step 2'b is formed by combining the system and the diffusion system.

Further, the optical system of the lamp unit 2 is not limited to the one using the normal lens 2b as in the first embodiment (shown in FIG. 1), but may also be an optical system as shown in FIGS. 2 to 4. That is, in the second embodiment shown in FIG. 2, the lens 2b is formed using a light guide plate material. This configuration has the advantage that the luminous flux utilization rate of the light source bulb 2a is higher than that of the first embodiment. In the third embodiment shown in FIG. 3, an outer lens 6 is installed outside the lens 2b. By configuring this way, the light from the light source bulb 2a can be controlled by the lens 2b and the outer lens 6 to be spread more widely and extend further, and at the same time, the appearance as a room lamp is improved. You will be able to do this. Further, in the fourth embodiment shown in FIG. 4, by forming a linear refractive lens step 6a on the outside of the outer lens 6, the design effect of the surface can be improved and a wider range can be illuminated. This is how it was done.

<Effects of the Invention> Since the automobile room lamp of the present invention is constructed in this manner, most of the light X from the lamp unit is irradiated toward the interior roof and reflected into the interior of the vehicle.
Therefore, there is no risk that the light from the lamp unit will directly enter the eyes of the passengers on board, and it will not cause any dazzling, and it will be possible to gently illuminate a wide area, making it suitable for mood lighting. It becomes something.

Moreover, unlike conventional room lamps that are attached to the outside of the side rail garnish, the lamps have a greater sense of unity with the vehicle body, and do not detract from the aesthetics of the interior of the vehicle, making them look good.

Therefore, the intended purpose can be achieved.
