The laser light of different wavelengths emitted by the laser 11 is incident to the spectroscope 1, the laser light emitted by the laser 11 comprises first wavelength light and second wavelength light, the first wavelength light is reflected by the spectroscope 1 to the wavelength conversion device, the wavelength conversion device converts the first wavelength light into light of different wavelengths to form illumination light, and the illumination light is emitted through the main lens 6; the second wavelength light is directly incident on the optical element 4 through the spectroscope 1, the optical element 4 is used for converting the point laser light into the surface laser light, and the second wavelength light is emitted as the detection light through the main lens 6 after being converted by the optical element 4.
In a preferred implementation of the present embodiment, the laser 11 includes a first laser diode for emitting laser light of a first wavelength, a second laser diode for emitting laser light of a second wavelength, and a driving system connected to the first laser diode and the second laser diode, respectively. The driving system can drive the first laser diode in a continuous driving mode, can drive the second laser diode in a pulse driving mode, and can also drive the second laser diode in a continuous driving mode.
In the use process of the lighting device integrated with the LiDAR system, the laser 11 emits laser light with different wavelengths, and the laser light emitted by the laser 11 comprises light with a first wavelength and light with a second wavelength. As shown in fig. 4, the laser light a (including the first wavelength light and the second wavelength light) emitted from the laser 11 enters the spectroscope 1, where the first wavelength light C reaches the wavelength conversion device after being reflected at the spectroscope 1, is converted into visible light D at the wavelength conversion device, and finally is emitted from the main lens 6.
