摘要： A high-definition lamp unit (110) contains a plurality of individually controllable pixels PIX, and emits lamp beam having light distribution corresponding to states of the pixels PIX. A first sensor (120) is provided to enable detection of a dynamic component θd of a pitch angle of a traveling vehicle body. A controller (200) shifts the level of a cut-off line CL of the light distribution up and down, corresponding to the dynamic component θd of the pitch angle of the vehicle body, with reference to a predetermined level defined as a base V0.

摘要： Provided is a vehicular lamp capable of notifying, when a subject vehicle approaches a corner with a blind spot, a pedestrian or other vehicles in the blind spot at the corner of the subject vehicle approaching the corner. In a vehicular lamp which includes an adaptive lamp unit (4L, 4R), an object detection signal acquirer (5, 14) that acquires an object detection signal around a vehicle, and an adaptive controller (6L, 6R) that adjusts an irradiation area and an irradiation light amount of the adaptive lamp unit (4L, 4R) based on the acquired object detection signal, the adaptive lamp unit (4L, 4R) is configured to irradiate a curve mirror (CM, CM1, CM2) detected around the vehicle with light based on an object detection signal of the curve mirror (CM, CM1, CM2).

摘要： Provided in the present disclosure are an interference lens (1) and a projection ambient lamp. The interference lens (1) includes: an interference sheet (11) with a first surface (12) and a second surface (13) opposite to the first surface, the first surface (12) being a rough surface; and a reflective film (14) provided at the interference sheet (11); wherein light is reflected by the reflective film (14) to form an interference pattern. The projection ambient lamp includes the foregoing interference lens (1), a light source (2) and a focusing lens (3); light emitted from the light source (2) passes through the interference lens (1) and is reflected by the reflective film (14) to form an interference pattern, which is focused by the focusing lens (3) and projected on a medium. The present disclosure realizes simplification of the structure by providing a reflective film at the interference lens, and does not need to provide individual reflector and refractive lens as compared with the prior art, hence utilization of light energy is higher, power consumption is lower, manufacturing cost is lower, and projection effect is better.

摘要： A light reflecting member (11) has a mirror face (111) adapted to reflect incident light (IL). A first arm member (121) and a second arm member (122) are bonded to the light reflecting member (11). A first actuator (131) and a second actuator (132) are configured to cause the first arm member (121) and the second arm member (122) respectively to displace in a direction intersecting the mirror face (111) to change an angle of the mirror face (111) relative to the incident light (IL). A thermal expansion coefficient of a material forming the light reflecting member (11) is smaller than a thermal expansion coefficient of a material forming each of the first arm member (121) and the second arm member (122).

摘要： A vehicular lamp system (1) comprises: an arithmetic unit (10) for extracting an index value from a predetermined processing target region in an image IMG; a pattern determination unit (12) for determining a light distribution pattern PTN such that the index value approximates a maximum value; and a lamp control unit (14) for controlling a variable light distribution lamp (2) so as to form the light distribution pattern PTN. The index value is at least one of an average intensity of HOG feature amounts in a plurality of pixels in the processing target region and an edge gradation proportion, which is a proportion of pixels belonging to a gradation of an edge part with respect to the whole of the plurality of pixels in a local binary pattern (LBP) histogram of the plurality of pixels.
