At least some of the light emitted from a light source passes through a projection lens (5). A lens holder (6) holds the projection lens (5). A right turning shaft (5a) and a left turning shaft (5b), which are provided to the projection lens (5), extend in an orientation intersecting the optical axis of the projection lens (5). A right bearing (6a) and a left bearing (6b), which are provided to the lens holder (6), respectively hold the right turning shaft (5a) and the left turning shaft (5b). An aiming screw (9) and a joint (5d) allow the projection lens (5) to turn relative to the lens holder (6) about the right turning shaft (5a) and the left turning shaft (5b).

A vehicle exterior observation device is provided with imaging devices (1L, 1R) and an image control unit (2). The imaging devices (1L, 1R) are each provided with: an imaging element (13) having an imaging surface; a first image-producing optical system (14t) configured so as to form, on the imaging surface, a first image of a first imaging area (13t) of the vehicle exterior at a first imaging magnification; and a second image-producing optical system (14w) configured so as to form, on the imaging surface, a second image of a second imaging area (13w) of the vehicle exterior at a second imaging magnification different from the first imaging magnification. The image control unit (2) is configured so as to detect the first imaging area (13t) and the second imaging area (13w), synthesize the first image and the second image on the basis of the detected first imaging area and second imaging area so that the first image and the second image are displayed in succession, and display the synthesized images on monitors (3L, 3R).

An automotive headlamp apparatus 10 includes a light source 14, in which a plurality of LED chips 12 are arranged at intervals from each other, and a projection lens 16 for projecting the light, emitted from the light source 14, toward a front area of a vehicle as a light source image. The semiconductor light-emitting elements may be located within than a focal point of the projection lens. The LED chip 12 is arranged such that the light emitting surface of the LED chip 12 faces the front area of the vehicle. The light emitting surface of the LED chip 12 may be of a rectangular shape and the LED chip 12 may be arranged such that a side of the light emitting surface is at a slant with respect to the vehicle width direction.

The vehicle lamp of the present disclosure includes a substrate, a heat dissipating member, a reflector, and a fastening member. The reflector includes a boss portion that protrudes toward the heat dissipating member side and includes a fastening hole. The substrate includes a first opening. The heat dissipating member is in contact with the substrate to be thermally conductive with the substrate and includes a first portion that includes a second opening, a second portion that is more spaced apart from the reflector than the first portion to include an insertion hole and a fastening seat surface, and a connecting portion that connects the first portion and the second portion to each other. The boss portion passes through the first opening and the second opening and abuts to the second portion such that the fastening hole and the insertion hole overlap with each other.

A reflecting surface of a reflector has a structure where a plurality of reflecting elements are arranged in rows in an up-and-down direction, and the reflecting elements are arranged as a plurality of sets in a left-and-right direction. The surface of each reflecting element is composed of a curved surface having a horizontal section curvature larger than a vertical section curvature. Thus, a horizontally long light distribution pattern may be easily formed by light reflecting from each reflecting element. Each reflecting element is connected to each of four reflecting elements which are adjacent thereto in the left-and-right direction and are shifted therefrom in the up-and-down direction, through a boundary line extending from a vertical plane in an inclined direction in the left-and-right direction. Thus, the horizontally long light distribution pattern formed by the light reflecting from each reflecting element becomes a bright light distribution pattern having four chipped corners.
