    摘要: A semiconductor light-emitting element includes: a growth substrate; a plurality of columnar semiconductor layers on the growth substrate; and an embedded layer with which the plurality of columnar semiconductor layers are covered. Each of the plurality of columnar semiconductor layers includes: an n-type nanowire layer at a center of each of the columnar semiconductor layers; and an active layer on an outer periphery side of the n-type nanowire layer. The embedded layer defines a gap above the growth substrate between adjacent columnar semiconductor layers of the plurality of columnar semiconductor layers.

    摘要: A light shielding plate for shielding part of light from a light emitting element to a projection lens is arranged between the light emitting element and the projection lens, and an opening penetrating the light shielding plate is formed in a required region of the light shielding plate. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening. In this configuration, the inner peripheral surface of the opening has such a surface shape that light emitted from the light emitting center of the light emitting element does not enter the projection lens. Thus, even if the plate thickness of the light shielding plate is increased, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface of the opening is effectively reduced.

    摘要: A vehicle system, in a vehicle that travels around a corner by tilting a vehicle body toward a turning direction, includes a light source, an optical member configured to form a predetermined light distribution pattern including a plurality of regions formed in parallel in one direction by irradiating a front side of a lamp with light from the light source, a sensor configured to detect a lamp position of an object outside the vehicle, and a control unit configured to determine an upper end position of the object based on the lamp position, and to adjust the predetermined light distribution pattern such that among the plurality of regions, a first region including the upper end position is not irradiated with the light.

    摘要: A first light emitting element emits first detecting light toward the outside of a vehicle. A second light emitting element emits second detecting light toward the outside of the vehicle. A first light receiving element outputs a first signal corresponding to an amount of incident light. A second light receiving element outputs a second signal corresponding to an amount of incident light. A processor acquires first data corresponding to the first signal and second data corresponding to the second signal, and exchanges the first data and the second data in a case where the first data is based on the second detecting light and the second data is based on the first detecting light.

    摘要: A vehicle headlight (10) includes a light source unit (30) including a plurality of light emitting elements (35), a reflector (39) that scans light from the plurality of light emitting elements (35) to form a light distribution pattern (350), and a control unit (60). The control unit (60) controls the light source unit (30) such that the light amount of light emitted from some light emitting elements to a predetermined region (AR) overlapping a target object does not change and the light amount of light emitted from other some light emitting elements to the predetermined region (AR) overlapping the target object changes among the light emitting elements that emit light to the predetermined region (AR) overlapping the target object in the superimposition region (PA).

    摘要: A vehicle lamp is configured in such a manner as to project light from light-emitting elements (22 and 42) of a first and a second lamp unit (20 and 40) forward through lenses (30 and 50) in the lamp and accordingly form a low-beam light distribution pattern having a Z-shaped cut-off line. In addition, a part of a plurality of lens elements formed on a front surface (30a, 50a) of each of the lenses (30 and 50) is formed as a specific lens element (30aA3, 50sB3) having a freeform surface shape. It is configured in such a manner as to form an inclined portion of the Z-shaped cut-off line with light emitted from the specific lens elements (30sA3 and 50sB3). Consequently, the degree of flexibility in forming the Z-shaped cut-off line is increased.

    摘要: Vehicle headlights are equipped with a right-side lamp, a left-side lamp, and a control unit. A right-side light distribution pattern and a left-side light distribution pattern include an overlapping area and a non-overlapping area. In a case where the steering angle is greater than the prescribed angle, the control unit controls power supplied to light-emitting parts of the right-side lamp and power supplied to light-emitting parts of the left-side lamp such that: a first area of a first light distribution pattern is located in the non-overlapping area; a second area of a second light distribution pattern is located in the overlapping area; and a first intensity of the light in the first area becomes greater than the sum of a second intensity of the light in the second area and a third intensity of the light in the area overlapping the second area within the first light distribution pattern.

    摘要: A light source unit used for a vehicular head-up display includes a prism-shaped multi-reflection member and a substrate. The multi-reflection member has: an entrance surface; an emission surface; and a reflective surface connecting the entrance surface and the emission surface. The substrate faces the entrance surface and is provided with a plurality of light sources mounted in a matrix. A ratio Ra=A/B or a ratio Rc=a/b is larger than a ratio Rb=C/D, where A and B is the number of the light sources provided in a longer and shorter direction of the entrance surface, respectively, C and D is a longer and shorter dimension of the emission surface, respectively, and a and b is the sum of lengths of light-emitting surfaces of the plurality of light sources in the longer and shorter direction of the entrance surface, respectively.
