DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a lighting device for an automobile door handle according to the present invention will be described below with reference to FIGS. 1 and 2 show a schematic configuration of a lighting device 10 of the present invention. The door handle main body 11 is arranged at a predetermined position outside the door, and the door knob 12 pivotally supported by the door handle main body 11 rotates as shown by a double arrow. A keyhole 13 is provided at an end of the door handle main body 11.

The illuminating device 10 has an illuminating lamp 14 formed along the lower part of the door handle main body 11. As shown in FIG. 2, the illumination lamp 14 has a lower portion of the door handle body 11 formed as a concave portion, and can illuminate the vicinity of a foot as shown in FIG. As shown, a lamp 15 is mounted in the recess of the illumination lamp 14 as a light source for illumination. As the lamp 15, for example, a light emitting diode or the like can be used. The lamp 15 is also ON / OFF controlled in conjunction with a door lock mechanism. In this embodiment, the lighting device 10 has a knob position indicator light 16 arranged along the lower part of the door knob 12, and further has a keyhole position indicator light 17 arranged around the keyhole 13.

The knob position indicating lamp 16 is formed by embedding a resin material such as acrylic in the door knob 12.
As shown in FIGS. 3 and 4, the light guide means 18, which preferably comprises an optical fiber, is connected to the end of the knob position indicator light 16. As a result, the lamp 1 from the illumination lamp 14 of the door handle body 11 to the knob position indicator light 16
5 light can be guided. Also, the keyhole position indicator light 17
Can also be formed of acrylic or the like. In this case, the light guide means 18 is branched on the way and connected to an appropriate position of the keyhole position indicating lamp 17. Illumination light 14, knob position indicator light 1
6 and the lighting color of the keyhole position indicating light 17 can be set by the emission color of the lamp 15, or can be set by the color of the forming material of the knob position indicating light 16 and the keyhole position indicating light 17 itself.

FIG. 5 shows an example of actual use of the lighting device 10. When the illuminating lamp 14 is turned on, the knob position indicating lamp 16 and the keyhole position indicating lamp 17 are simultaneously turned on via the light guide 18. The illumination lamp 14 capable of illuminating the vicinity of the foot in this way
And the knob position indicating light 16 and the keyhole position indicating light 17 are integrally formed, thereby exhibiting a high illumination function while having a compact structure. For example, it is possible to easily find a puddle or an obstacle at the foot by turning on the illuminating light 14, or to easily and accurately confirm the knob position and the keyhole position by turning on the knob position indicating light 16 and the keyhole position indicating light 17. . The lighting of the illuminating lamps 14 and the like can also function as a warning lamp for a half-door state of the side door, forgetting to close the window, and the like.

In the above operation, as shown in FIG. 5, the illuminating lamp 14, the knob position indicating lamp 16 and the keyhole position indicating lamp 17 can be turned on with the side door closed. When this lighting operation is performed by keyless entry, when the door is unlocked by remote control operation of the door key, the illumination lamp 14 and the knob position indicating lamp 16 are turned on in conjunction with the unlocking operation. At this time, the keyhole position indicator light 17 may be turned on at the same time, but it is not always necessary to turn on the keyhole position indicator light 17 simultaneously if the door can be locked and unlocked by a keyless entry type. Absent.

According to the illuminating device 10 of the present invention, unlike the conventional courtesy lamp (FIG. 6), it is possible to illuminate the vehicle without opening the side door. You can check the safety of the neighborhood. Also, unlike the conventional opening lamp (FIG. 6), by lighting without opening the side door, high visibility (FIG. 5,
An arrow C) can be given, and the lighting is performed at a position that is easy to see, so that high security can be obtained.

[0017]

As described above, according to the present invention, it is possible to get on and off the vehicle safely and smoothly at night or in the dark, thereby ensuring high safety and realizing excellent convenience and ease of use. Can be. In addition, by combining a plurality of lighting functions into one compact configuration, there is an advantage that it is extremely advantageous also in a side door configuration.
