Abstract: A headlight (1) includes a lamp unit (20) including: light sources (52R,52G,52B) that emit laser light; and phase modulation elements (54R,54G,54B) that diffract the laser light emitted from the light sources (52R,52G,52B) with a phase modulation pattern that is changeable, and emit light of a light distribution pattern based on the phase modulation pattern. The lamp unit (20) adjusts a total luminous flux amount of light emitted from the lamp unit (20) according to the light distribution pattern.

Abstract: An active sensor includes a light projector configured to emit probe light, and an image sensor. The active sensor is configured to obtain a first image in a light emitting state of the light projector and a second image in a non-light emitting state of the light projector. The second image can be used for correcting the first image.

Abstract: Provided is a vehicular lighting device (1) attached to a motorbike (100) that is capable of traveling around corners due to the vehicle body being tilted toward the direction for turning, wherein the vehicular lighting device (1) comprises at least two lamps and a sensor (7) for detecting the surrounding environment toward the rear of the vehicle. The vehicular lighting device (1) comprises a left lighting unit (2L) and a right lighting unit (2R) as the at least two lamps. The sensor (7) is disposed between the left lighting unit (2L) and the right lighting unit (2R) as viewed from rearward of the vehicle.

Abstract: This vehicular lighting equipment provided on a vehicle (100), which is capable of travelling around a corner by tilting the vehicle body toward the turning direction, comprises a light source, an optical member by which the light emitted from the light source is directed forward from the lighting equipment to form a predetermined light distribution pattern (PL), and a control unit for adjusting the predetermined light distribution pattern (PL) according to the tilted state of the vehicle body. The control unit is configured to adjust a predetermined light distribution pattern (PL2) such that in a light distribution pattern (PL1) corresponding to when the vehicle body is tilted, no light is irradiated in a region located outside the light distribution pattern (PL) corresponding to when the vehicle body is in the vertical state.

Abstract: This lighting circuit comprises a current source and a thermal sensing element. The thermal sensing element senses the temperature of a semiconductor light source. The current source generates a drive current that shows a positive correlation with the temperature when the temperature is in a normal range and that shows a negative correlation with the temperature when the temperature falls within a temperature range higher than the normal range.

Abstract: A camera module shoots a satisfactory image by suppressing the adherence of water droplets to a part in a light transmitting cover through which imaging light is transmitted. Provided are an outer casing comprising a housing having an opening and a light transmitting cover for closing the opening; and a camera module arranged inside the outer casing. A part of the light transmitting cover is provided as a transmission window through which imaging light incident on the camera module is transmitted and a restriction part for restricting the inflow of water droplets toward the transmission window is provided to the light transmitting cover.
