A vehicular vision system includes a camera disposed at a vehicle and having a field of view exterior of the vehicle, a light source disposed at the vehicle and operable to emit light, and a control. Light emitted by the light source, when operated, illuminates a field of illumination exterior of the vehicle, with the field of view of the camera encompassing at least a portion of the field of illumination. The control, responsive to data processing by a processor of the control of image data captured by the camera, determines a change in the field of illumination provided by the light source. Responsive to the determined change in the field of illumination, the control at least one selected from the group of (i) adjusts the light source to accommodate the determined change, (ii) adjusts the camera to accommodate the determined change and (iii) generates an alert.

A bending light device for a vehicle diffracting light emitted from a light source and deflecting the light at a desired angle and in a desired direction may include an ultrasonic light deflector configured to diffract light incident thereon in a selected direction by emitting an ultrasonic beam to the incident light, a light reflection unit configured to reflect light emitted from a light source to the ultrasonic light deflector, a projection lens configured to project light incident thereon after passing through the ultrasonic light deflector to radiate the light outside, and a converging lens arranged between the ultrasonic light deflector and the projection lens and configured to converge the light having passed through the ultrasonic light deflector on the projection lens.

In various embodiments, a lighting device is provided. The lighting device includes at least one light source for emitting primary light, at least one phosphor body which is illuminatable by the primary light and is spaced apart from the at least one light source, and at least one light scattering body which is situated optically downstream of the phosphor body in a light propagation direction of the primary light that is uninfluenced by the phosphor body. The lighting device is designed in the case of an intact phosphor body to generate an illumination pattern by light generated by the phosphor body, and otherwise to generate a light emission pattern by light generated by the at least one light scattering body. The light emission pattern differs from the illumination pattern.

A lamp control device comprises a first input terminal, a second input terminal, an output terminal that is configured to be connectable to a lamp via an external switch and outputs a drive current for the lamp, an internal switch provided on a first path connecting the first input terminal and the output terminal, a constant current section provided on a second path connecting the second input terminal and the output terminal, a voltage monitoring section that monitors a voltage applied to the output terminal, and a control section that controls the internal switch on the basis of a monitoring result from the voltage monitoring section.

An illumination device includes a laser element, a fluorescent material, a light projection lens, a laser light reflector, a detection element, and a control unit connected to the detection element. The fluorescent material is disposed in a direction of propagation of laser light from the laser element, and converts the laser light into illumination light. The light projection lens and the laser light reflector are disposed in a direction of propagation of the illumination light from the fluorescent material. The detection element can detect the laser light reflected on the laser light reflector and external light. The control unit calculates a comparison value by comparing the amount detected by the detection element when the laser element is emitting the laser light and the amount detected by the detection element when the laser element is not emitting the laser light. When this comparison value becomes larger than the first threshold, the control unit stops or attenuates the laser light from the laser element.

It is an object of the present invention to provide a technology capable of increasing accuracy of determining a failure in a lighting device. A video acquisition unit acquires a video of an area including an illumination target area of a lighting device. A determination unit determines whether the lighting device is faulty on the basis of a video of the illumination target area of the video acquired by the video acquisition unit in cases in which an ON signal is supplied to the lighting device and a current position acquired by a position acquisition unit is a predetermined determination position where determination of a failure should be performed.

A lighting device includes a thermal sensor, power converter circuits and a control circuit. The thermal sensor is configured to measure an internal temperature of a case.

The control circuit is housed in the case and has priorities that are provided with respect to the different types of light sources according to their respective types. The control circuit is configured to, when the internal temperature is greater than a threshold, control the respective outputs of the power converter circuits so as to preferentially decrease an output for a light source corresponding to a first priority.

A vehicle illumination apparatus is disclosed. The apparatus comprises at least one aperture disposed in a panel of the vehicle. A light source is disposed proximate the aperture and configured to emit a first emission having a first wavelength. A first photoluminescent portion is disposed proximate the panel substantially within the aperture and configured to emit a second emission having a second wavelength in response to receiving the first emission.
