JP 2012-101680 A

By the way, it is necessary to attach the control light so as to emit light toward the road surface on the side of the vehicle so as not to dazzle other vehicles and pedestrians. Therefore, for example, when a control light is attached to a door or a fender, it is attached so as to protrude outward, and there is a problem that the appearance design of the vehicle is impaired. As described above, when a control light that has not existed until now is newly attached to the vehicle, how to attach the control light without impairing the appearance design of the vehicle is a problem.
The present invention has been made in view of the above points, and an object of the present invention is to provide a vehicular lamp capable of attaching a control light to a vehicle without impairing the appearance design of the vehicle.

  The invention according to claim 1 is a vehicular lamp including a housing, and a first light source and a second light source provided in the housing. The housing can be attached to an exterior part of the vehicle, has a facing surface that faces the road surface on the side of the vehicle when attached to the vehicle, and can transmit light. The first light source emits light that indicates the vehicle traveling direction when the vehicle turns right or left. When the housing is attached to the vehicle, the second light source emits light that illuminates the road surface on the side of the vehicle and assists in the operation of the vehicle.

  The vehicular lamp functions as a direction indicator and also functions as a control light. Accordingly, by attaching the vehicular lamp of the present invention instead of the direction indicator originally attached to the vehicle, the control light can be mounted on the vehicle without impairing the appearance design of the vehicle.

  The invention described in claim 2 includes a substrate on which both the first light source and the second light source are attached. Therefore, since it can be set as the integrated structure which mounted the 1st light source and the 2nd light source on one board | substrate, while the structure of a 1st light source and a 2nd light source becomes simple, the assembly | attachment of a 1st light source and a 2nd light source is carried out. Work becomes easy.

The invention according to claim 3 is provided between the housing and the first light source and the second light source, the first through hole through which the light emitted from the first light source passes, and the first through which the light emitted from the second light source passes. A shielding member having two through holes is provided. Therefore, for example, a member such as a substrate can be hidden from the outside, and the appearance is good.
In the invention according to claim 4, the outer surface of the shielding member facing the inner surface of the housing can reflect light, and functions as a reflector. Therefore, it is not necessary to separately provide a reflector, and the number of parts can be reduced.

In the invention according to claim 5, the second light source is an LED. The light emitted from the LED is highly linear, and the light emitted from the second light source is irradiated downward and hardly diffuses in the lateral direction. For this reason, when the second light source emits light, it is difficult to misunderstand that the first light source emits light. That is, when the control light is lit, it is difficult to be mistaken for the direction indicator being lit.
The invention described in claim 6 includes a housing body that closes the opening of the outer lens. Therefore, the first light source and the second light source can be provided in an environment where rainwater is not applied.

  In the invention according to claim 7, the light emitted from the first light source is orange, the light emitted from the second light source is white, and the housing is colorless. By making all the housings colorless, which is the same color, the housing can be manufactured at low cost.
