[0037] figure 1 It is a perspective view of a vehicle 1 equipped with a turn signal lamp 10 according to the first embodiment of the present invention. Such as figure 1 As shown, at least a part of the turn signal lamp 10 is disposed on the side of the vehicle body. The turn signal lamp 10 is provided on the front fender 4 forming the wheel house 3 of the front wheel 2 . A pair of left and right turn signal lamps 10 are respectively provided on the right side and the left side of the vehicle 1 .

[0038] exist figure 1 The vehicle 1 shown is not provided with sandboard mirrors and reverse mirrors. The rear viewing function of the sandboard mirror and the side-view mirror is performed by the camera 50 mounted on the turn signal lamp 10 which will be described later. The right turn signal lamp provided on the right side of the vehicle 1 includes a right camera inside. The left turn signal lamp provided on the left side of the vehicle 1 includes a left camera inside. The r...

[0074] Figure 8 It is an exploded perspective view of a turn signal lamp 10A according to the second embodiment of the present invention. Such as Figure 8 As shown, the turn signal lamp 10A according to the present embodiment differs from the first embodiment in the shape of the light guide 30A. The light guide body 30A does not have a sub-light guide portion. The turn signal lamp 10A according to the present embodiment can light the main light portion 32A using the light that lighted the sub light guide portion 33 in the turn signal lamp 10 according to the first embodiment, so that the main light portion 32A can be made to emit light more brightly.

[0075] In the present embodiment, the light guide body 30A is arranged in a region extending from the camera 50 in a direction along the surface of the front fender 4 . Therefore, visibility can be improved and an increase in air resistance due to the turn signal lamp 10A can be suppressed.

[0077] Figure 9 It is an exploded perspective view of a turn signal lamp 10B according to the third embodiment of the present invention. Such as Figure 9 As shown, the turn signal lamp 10B according to the present embodiment differs from the first embodiment in the shapes of the lamp body 11B, the light guide body 30B, the additional body 40B, and the housing 12 .

[0078] The light guide 30B has an incident part 31B, a rear end part 34B located above the camera 50, a main light guide part 32B, and a sub light guide part 33B. The main light part 32B is an arched part, and connects the incident part 31B and the rear end part 34B in an arched shape. The sub light guide portion 33B is a plate-shaped portion extending downward from the main light guide portion 32B. The sub light guide part 33B is provided with a slit extending in the vertical direction. The thickness in the left-right direction of the sub light guide part 33B is smaller than the thickness in the left-right d...

Abstract

The invention provides a turn signal lamp having a camera and a light guiding body and can inhibit the increase of the air resistance. Provided is a turn signal lamp (10) including a light source (20), a light guiding body, and a camera having an image capture device, which are installed within a lamp chamber (S) formed by a lamp body (11) and an outer cover (12). At least a portion of the light guide is formed in an area that extends from the camera in a direction following a vehicle surface.

Description

technical field [0001] The present invention relates to turn signal lamps. Background technique [0002] As described in Patent Document 1, it is proposed to eliminate the rearview mirror and replace it with a turn signal lamp equipped with a camera capable of acquiring an image of the rear of the vehicle. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2003-312359 [0005] The inventors of the present invention considered improving the visibility of the turn signal lamp by mounting a light guide in such a turn signal lamp. However, if the camera and the light guide are mounted inside the turn signal lamp, the size of the turn signal lamp may increase and the aerodynamic resistance of the vehicle may increase. Contents of the invention [0006] Therefore, an object of the present invention is to provide a turn signal lamp which has a camera and a light guide and can suppress an increase in air resistance. [0007] The turn signal...
