Vehicle light optical element, vehicle light module, vehicle headlight, and vehicle

A vehicle light optical element (VLOE) comprises a light incident portion, a transmission portion, and a light emitting portion sequentially arranged from back to front. The light incident portion comprises an illuminating light incident structure (ILIS) and at least one high-beam light incident structure (HBLIS), in which an illuminating light incident surface of the ILIS is adapted to receive auxiliary light during low-beam lighting. Alternatively, the light incident portion comprises an ILIS and at least one HBLIS, in which the ILIS is either a flat surface, a curved cylindrical body protruding backwards, a hemispherical body protruding backwards, or a light condensing structure. The ILIS is adapted to receive auxiliary lighting light during low-beam lighting. The ILIS is provided on the VLOE, such that when a vehicle light is in a low-beam lighting mode, the VLOE is also luminous, thereby improving the aesthetic appearance of the vehicle light.

LIGHTING CIRCUIT AND VEHICULAR LIGHTING DEVICE

A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

Headlight control system

A headlight control system has a headlight including a plurality of LED light sources, a camera and a radar that detect a predetermined target object present ahead of a vehicle, and a controller configured to control the headlight such that, when the target object is present, of the plurality of LED light sources, the LED light source irradiating a region where the target object is present is turned off, and such that, thereafter, when the target object is no longer present in the region, the turned-off LED light source is turned on again. The controller controls the headlight such that, at the time of turning on the turned-off LED light source again, a change rate of luminance of the LED light source is changed according to a position of an irradiation region of the LED light source.
