According to this method, in order to turn on the room lamp, the switch knob is pushed in. When pressed, the switch knob will stop at the pushed in position and the lamp will turn on. lamp The light illuminates the interior of the vehicle through a lamp lens. At this time, the lamp lens Extend a part of the lamp between the lamp installation part and the switch installation part, and use the extended part to install the lamp. It creates a separation between the installation part and the switch installation part, and also the position where the switch knob is pushed in. Since the lamp is stopped at a fixed position, the area of the light beam that illuminates the interior of the vehicle is It's probably wider than before.

[0008] Then, when you press the switch knob again, the switch knob will touch the indoor side of the object to which it is attached. It returns to a substantially flush position and the lamp part turns off.

[0009]

【Example】

This invention will be explained below based on examples.

0010 Figure 1 illustrates a room lamp device according to an embodiment of this invention using a map lamp. This is a diagram.

[0011] First, to explain the configuration, the installation opening of the roof inner trim 11, which is the object to be installed. 11a includes a halves in which the lamp arranging part 12 and the switch arranging part 13 are formed adjacent to each other. The housing 14 is inserted and its peripheral edge 14a is locked in the mounting opening 11a. It is arranged in a state. A push-button switch 13b is attached to this switch arrangement portion 13 with screws. 13c, and when the switch is turned on, this push button is located at the position indicated by the solid line in the figure. When the switch knob 13a of the switch 13b stops and the switch is turned off, corresponds to a position substantially flush with the interior side surface 11b of the roof inner trim 11 shown by the dotted line in the figure. The switch knob 13a is set to stop.

0012 In addition, a push button switch 13b is provided in the lamp installation section 12 to turn it on and off. A bulb 15 as a lamp section is provided. And the light from this bulb 15 A substantially spherical reflector 16 that reflects the light is arranged on the back side of the bulb 15. , a lamp that transmits and refracts the light from the bulb 15 and the reflected light from the reflector 16. A lens 17 is provided. The lower surface portion 17a of this lamp lens 17 is If the inner trim 11 protrudes too much from the interior side surface 11b, the appearance will be spoiled. So Here, this lamp lens 17 is roughly connected to the indoor side surface 11a so as not to spoil the appearance. The lamp lens 17 is set in a flush position, and a part of the lamp lens 17 is flush with the lamp installation part 12. and the switch arrangement portion 13 to form an extension portion 17b. child In this embodiment, the extension portion 17b is bent into a substantially L-shape from the lower surface portion 17a. , there is a space between the lamp installation part 12 and the switch installation part 13 that is approximately perpendicular to the lower surface part 17a. By directly arranging the lamp arranging part 12 and the switch arranging part 13, the distance between the lamp arranging part 12 and the switch arranging part 13 is I'm trying to make it happen. However, the extension portion 17b is not limited to such a configuration, and the extension portion 17b is not limited to such a configuration. It may be constructed of a separate member rather than integral with the member of the portion 17a, and the extension Any configuration may be adopted as long as it provides separation between the section 17b and the lamp installation section 12. It's okay.

[0013] In addition, the code|symbol 18 in FIG. 1 is a shade.

[0014] Next, the operation of the map lamp having such a configuration will be explained.

[0015] Now, to turn on the bulb 15, push the switch knob 13a up from the bottom in the figure. When the switch knob 13a is turned on, the switch knob 13a is locked and stopped at the position shown by the solid line, and the valve is closed. The bulb 15 lights up. The light beam from the bulb 15 enters the vehicle interior 19 via the lamp lens 17. Illuminate the side. At this time, a part of the lamp lens 17 is connected to the lamp installation part 12. The extension part 17b connects the lamp arrangement part 12 and the switch. and the switch knob 13a is in the pushed-in position. Therefore, the area L2 of the light beam irradiated into the vehicle interior is The width can be increased by the length of the extended portion 17b compared to the conventional one. Like this The light beam is not obstructed by the switch knob 13a, and the lamp installation part 12 and the switch arrangement are connected to each other. The lamp lens 17 becomes wider due to the extension part 17b that separates it from the installation part 13, and Since the area L2 of the light beam irradiating the interior can be expanded, the map lamp device main body The area L2 of the light beam can be increased without increasing the area L2.

[0016] Then, push up the switch knob 13a again to release the locked state and switch the switch. The switch knob 13a is attached to the interior side surface 11 of the roof inner trim 11 shown by the two-dot chain line in the figure. It returns to a position substantially flush with b, and the bulb 15 turns off. When the light is off, the switch knob 13a stops at approximately the same position as the indoor side surface 11b of the roof inner trim 11. Therefore, it does not spoil the appearance.

[0017] In this example, the map lamp was used as the room lamp. , Can be used not only as a map lamp but also as a reading lamp or any other room lamp. Of course.

[0018]

[Effect of the idea]

As explained above, according to this invention, a part of the lamp lens can be The extension part connects the lamp mounting part and the switch mounting part. The switch knob is pushed in when the switch is ON. Since the vehicle is stopped in a closed state, the area of the light beam that illuminates the interior of the vehicle can be It can be expanded. Therefore, the light beam can be emitted without increasing the size of the room lamp device itself. Sufficient area can be secured, and there is no risk of increased weight or cost. It was.

[0019] In addition, when the switch is off, the switch knob is approximately flush with the indoor side surface of the object to be installed. Since it returns to the first position and stops, it does not spoil the appearance.
