Embodiment 1

[0040] Such as Figure 1-Figure 5 As shown, the lighting device integrated with the LiDAR system provided by the embodiment of the present invention includes: a laser 11 and an optical path module, and the optical path module includes: a wavelength conversion device, an optical element 4, a light reflector 1, and a main lens 6, wherein:

[0041] Lasers of different wavelengths emitted by the laser 11 are incident on the wavelength conversion device, and the lasers emitted by the laser 11 include lasers of the first wavelength and lasers of the second wavelength. The laser light with the first wavelength is converted into light of different wavelengths by the wavelength conversion device to form illumination light, and the illumination light is emitted through the main lens 6 . The second wavelength laser is reflected to the light reflection mirror 1 by the wavelength conversion device, and then reflected to the optical element 4 through the reflection mirror. The optical eleme...

Embodiment 2

[0066] Another object of the embodiments of the present invention is to provide a car, which includes a car body, and the car body is installed with the lighting device integrated with the LiDAR system provided in the first embodiment.

[0067] Compared with the prior art, the advantages of the automobile and the lighting device integrated with the LiDAR system mentioned above are the same, and will not be repeated here.

Abstract

The invention provides a lighting device integrated with a LiDAR system and an automobile, relates to the technical field of automobile lighting and detection, and provides a brand-new fusion scheme of an automobile lamp and LiDAR. The lighting device integrated with a LiDAR system comprises a laser and a light path module; the light path module comprises a wavelength conversion device, an opticalelement, a light reflecting mirror and a main lens; laser with different wavelengths emitted by the laser is incident to the wavelength conversion device, and laser with the first wavelength is converted into illumination light through the wavelength conversion device and emitted out through the main lens; laser with the second wavelength is reflected to the light reflecting mirror through the wavelength conversion device, reflected to the optical element through the reflecting mirror, converted through the optical element and then emitted out through the main lens to serve as detection light. According to the lighting device integrated with a LiDAR system, point laser is changed into surface laser through the optical element, so that the blue light power is reduced, and the risk of high-power blue light is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile lighting and detection, in particular to a lighting device integrated with a LiDAR system and a car. Background technique [0002] With the development of vehicles, the uses of car lights are gradually diversified. In addition to lighting functions, some car lights also have the functions of laser detection and distance measurement for vehicles. [0003] A vehicle light includes two light sources, and the beams generated by the two light sources have different wavelengths, wherein the first light source emits blue laser light, and the second light source emits infrared laser light. The blue light generated by the first light source is reflected into the wavelength conversion device, converted into visible white light, and then emitted directly through the lens to be used for vehicle lighting; the infrared laser generated by the second light source is emitted through the lens after several refle...
