In addition, when it is dim, the position lamp bulb 5 is turned on. The specifications for Europe stipulate that when this position lamp is turned on, a certain level of light intensity is required at an angle of 80 degrees to the front of the vehicle.

[The problem that the idea attempts to solve]

However, since the above-described conventional headlamp has the position lamp bulb 5 attached to the effective reflective surface 20 of the reflector 2, the area of the effective reflective surface 20 of the headlamp reflector 2 is reduced. In addition, since the position lamp bulb 5 is disposed below the head lamp bulb 3, the light from the head lamp bulb 3 illuminates the position lamp bulb 5, and the shadow of the position lamp bulb 5 is cast onto the reflector 2. is reflected on the reflective surface 20 of the reflector 2, and as a result, there is a problem that the effective reflective surface 20 of the reflector 2 is further reduced.

The present invention provides a headlamp that does not reduce the effective reflection surface 20 of the headlamp reflector even if it is equipped with a position lamp bulb, and that can reliably illuminate a predetermined direction when the position lamp is turned on. The purpose is to provide.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a headlamp bulb, a reflector that reflects light from the headlamp bulb to a front lens, and a position lamp bulb, and has ineffective reflection on both sides of the reflector. In the headlamp, the position lamp bulb is disposed in one ineffective reflection part of the reflector, and the incident light from the position lamp bulb is directed into the other ineffective reflection part in a desired direction. It is characterized by forming a reflecting surface of the position lamp.

[Effect]

As described above, in the present invention, the position lamp bulb is disposed on one of the ineffective reflection parts of the reflector, so a dead space for disposing the position lamp bulb is formed on the effective reflection surface of the headlamp reflector. never be done. Also,
When lighting the position lamp bulb,
The light incident from the position lamp bulb is reliably reflected in the desired direction (e.g. 80° direction for Europe) by the position lamp reflection surface formed on the other ineffective reflection part, allowing it to function as a position lamp. can be improved.

〔Example〕

Hereinafter, one embodiment of the headlamp according to the present invention will be described with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, the same reference numerals as in FIGS. 3 and 4 indicate the same parts. In FIGS. 1 and 2, reference numeral 6 denotes a position lamp bulb, and this position lamp bulb 6 is a glass tube 60 containing a filament (not shown).

It is equipped with Reference numeral 17 denotes a mounting hole for a position lamp bulb provided at a location corresponding to one of the ineffective reflection portions 22 of the reflector 2 of the housing 1. 25 is one invalid reflection part 2 of the reflector 2
The through hole 25 is provided at a location corresponding to the mounting hole 17 of the housing 1 in No. 2, and the inside diameter of the through hole 25 is slightly larger than the outside diameter of the base 61 of the position lamp bulb 6. Reference numeral 26 denotes a reflective surface provided on the surface of the ineffective reflective part 22 provided with the through hole 25 of the reflector 2 and the other ineffective reflective part 22' on the reflective side. is formed so as to reflect it in a predetermined direction.

Since the headlight of the present invention has the above configuration, when the headlamp bulb 3 is turned on at night,
The light from the headlamp bulb 3 is reflected by the reflective surface 20 of the reflector 2 toward the front lens 12, and the reflected light is controlled by the front lens 12 to illuminate the front in a predetermined pattern. At this time, since the position lamp bulb 6 is disposed on one of the ineffective reflection portions 22 of the reflector 2, no ineffective portion will be formed on the reflection surface 20 of the headlamp reflector 2.

In addition, when the position lamp bulb 6 is turned on when it is dim, the light from the position lamp bulb 6 is reflected by the reflection surface 26 of the other invalid reflection portion 22', and the reflected light is directed in a predetermined direction, for example. Front lens 1 at an angle of 80° to the front of the vehicle.
