The present disclosure relates to a driving assistance system, includes: a light detection and ranging module configured to detect position parameters of objects around the light detection and ranging module; a LiFi driving module connected to the light detection and ranging module and being capable of receiving the position parameters and modulating the position parameters to generate a LiFi signal; and a lighting module connected to the LiFi driving module, and configured to provide lighting and transmit the LiFi signal.

Disclosed is a Light Detection and Ranging (LiDAR)-integrated lamp device configured for a vehicle. In the included LiDAR-integrated lamp device, the position at which a head lamp is applied and the position at which a LiDAR is applied are identical and then, a reduction in layout is achieved. Furthermore, through sharing of constituent elements, the number of constituent elements is reduced and then, manufacturing costs are reduced.

In an illumination device, an incidence angle of a laser beam, which is scanned by a laser beam scanning mechanism, with respect to a wavelength conversion member is set to an angle where the laser beam does not directly enter a projection lens when the wavelength conversion member is damaged, chipped or fallen off, and a laser light source and the laser beam scanning mechanism are located at a position corresponding to at least one of an upper side and a lower side of a light distribution pattern with respect to the wavelength conversion member, and are disposed to be deviated to either one of one side corresponding to a left side of the light distribution pattern and other side corresponding to a right side of the light distribution pattern.

A laser-based light source includes a laser device configured to generate laser light of a predetermined laser wavelength and emit this laser light as a laser beam. A light-conversion device is configured to convert at least part of the laser light into converted light and a laser-output sensor is configured to determine a laser-output signal proportional to the output of laser light emitted by the laser device. Further, a converted-light sensor is configured to determine a converted-light signal proportional to the output of converted light emitted by the light-conversion device. A controller is configured to receive the laser-output signal and the converted-light signal, to determine a safe-to-operate parameter, based on the laser-output signal and the converted-light signal, and to control the operation of the laser-based light source based on a comparison of the safe-to-operate parameter with a at least one predefined threshold.

A laser light source unit for vehicles is provided, having a resonator containing a first end mirror and a second end mirror and an active laser medium in between. The laser light source unit has a pump device for generating a pump radiation into the resonator. The pump radiation is configured such that laser light of the first wavelength, a second wavelength, and/or a third wavelength can be radiated. An intermediate mirror is configured so that the radiation of the second wavelength is reflected, and the radiation of the third wavelength is transmitted. A third end mirror is configured so that the radiation of the second wavelength is reflected. A color control module acts on the radiation of the second wavelength and/or the third wavelength so that an intensity of the stimulated emission of the radiation of the second wavelength is adjusted to the radiation of the third wavelength.
