Abstract: A light guide includes a first incident portion at an end side thereof near a light source, a stepped portion disposed on a rear surface side thereof in an axial direction and wholly reflects a portion of guided light, and a radiating portion disposed on a front surface side thereof in the axial direction that radiates the wholly reflected light forward. The light guide guides light that is incident through the first incident portion from front to back within the light guide. The stepped portion is a plurality of generally triangular prisms formed continuous in an extension direction, and has, in a cross section that follows an extension axis of the light guide and is parallel to a lamp optical axis, a long first projection surface that extends in the extension direction and a short second projection surface that forms an apex angle with the first projection surface.

Abstract: A vehicle lamp includes, within a lamp chamber formed by a lamp body and a front cover, a light source, a columnar light guide having an incident portion at the end thereof in the vicinity of the light source, and an annular reflecting portion arranged in the vicinity of the light source side of the incident portion. The columnar light guide guides incident light from the light source, which enters via the incident portion, and irradiates the incident light from a light-emitting portion on a front side. The annular reflecting portion reflects light with a large emission angle, which has not been able to directly enter the incident portion from the light source, toward the incident portion. The light source is arranged on a central axis of the annular reflecting portion.

Abstract: Light emitted from a light source 12a is sequentially reflected on a first, second, and third additional reflectors in this order. By emitting light in the order of the reflectors, this allows the light to be parallel to an optical axis by an additional lens. Accordingly, it is possible to increase the light-emitting area of the entire headlamp, thereby improving the appearance of the headlamp with respect to the driver of the oncoming vehicle. The additional lens is formed to have a substantially wedge-shaped cross-section, and is provided along the surface shape of a projection lens. Furthermore, since the light emitted from the light source is sequentially reflected by the first, second, and third additional reflectors in this order, the light emitted from the light source can be focused and the quantity of the light passing through the additional lens is not excessively increased.

Abstract: Optical axes are simultaneously adjusted by tiltably mounting a plurality of lighting device units on a common unit support member. A rectilinear propagation blocking member of each lighting device unit is fixed with screw via the elastic bush to the unit support member, so that the optical axis can be adjusted. Due to the above structure, even when the accuracy of shapes of the rectilinear propagation blocking member and the unit support member are not sufficiently ensured and also even when the accuracy of the attaching work can not be sufficiently ensured, the optical axes of the lighting device units can be arranged in order by adjusting the optical axis of the rectilinear propagation blocking member.

Abstract: A headlight has a plurality of lighting device units and a unit support member that supports the plurality of lighting device units. Each lighting device unit has a projection lens, a light emitting diode arranged behind a rear side focus of the projection lens, and a rectilinear propagation blocking member that is arranged in a vicinity of the rear side focus, and blocks a rectilinear propagation of a portion of light emitted from the light emitting diode so as to form a cutoff line. The projection lens and the rectilinear propagation blocking member are integrally formed as a light control member in each light device unit.

Abstract: An infrared light radiating lamp in which red light emitted from a front lens is diluted so as to become inconspicuous by emitting a small amount of visible light from a rim portion of a convex lens so that the lamp will not be mistaken for a tail lamp or a stop lamp and without causing glare. A vehicular infrared light radiating lamp is provided with a light source unit including a convex lens mounted via a lens holder forward of a reflector in which a light source is mounted. An infrared light transmitting film is provided on the rear surface of the convex lens. An infrared light transmitting film-free region is provided on the outer periphery of the infrared light transmitting film such that white visible light for diluting the red light emitted from the convex lens is emitted from the rim portion of the convex lens. Visible light with a high energy density is blocked by a light shielding member provided on the rear of the ring-shaped infrared light transmitting film-free region such that only visible light with a reduced energy density, namely, light dampened in intensity by reflection from the infrared light transmitting film, reaches the infrared light transmitting film-free region. Therefore, visible light emitted from the rim portion of the convex lens with an adjusted light intensity does not create glare.
