Therefore, a lens such as an inner lens is required to correct the direction of the light flux. First, the desired light distribution can be easily obtained using only the outer lens.

[0082] In the above embodiment, the vehicle marker lamp of the present invention is installed inside the rear window of the automobile. This section explains what is applied to high-mounted stop lamps that can be installed on the side. However, the vehicle marker light of the present invention is not limited to this. It can be applied to general vehicle marker lights that are curved so as to protrude forward.

[0083] Further, in the above embodiment, the rear surface of the light emitting diode holding member has many flat parts. Although we have explained the structure formed in a continuous step-like manner, it is not limited to this. The rear surface of the card holding member may be a curved surface with a central portion protruding forward.

[0084] Furthermore, the specific configuration shown in the above embodiment is applicable to the implementation of the vehicle marker light of the present invention. These are only a few examples, and these do not exceed the technical scope of the present invention. The boxes should not be construed as limiting.

Claims (1)

[Scope of utility model registration request] [Claim 1] A vehicle marker light whose front surface is curved so that the center portion in the left-right direction protrudes forward, and in which a plurality of light-emitting diodes held by a light-emitting diode holding member are arranged in the left-right direction inside the light body. The light-emitting diode holding member is formed with a large number of light-emitting diode holding holes that penetrate in the front-rear direction and are substantially parallel to each other. Arranged in a stair-like manner to be located at the rear,
The light-emitting diodes are inserted into the light-emitting diode holding holes from behind and held in the light-emitting diode holding holes, and the light-emitting diodes are arranged so that the ones closer to both left and right ends are located at the rear, and a flexible printed circuit board is mounted on the rear side of the light-emitting diode holding member. A marker light for a vehicle, characterized in that a light emitting diode lead is connected to the circuit pattern of the flexible printed circuit board.
