Abstract
The present disclosure provides a mobile machine including a laser diode based lighting system having an integrated package holding at least a gallium and nitrogen containing laser diode and a wavelength conversion member. The gallium and nitrogen containing laser diode is configured to emit a first laser beam with a first peak wavelength. The wavelength conversion member is configured to receive at least partially the first laser beam with the first peak wavelength to excite an emission with a second peak wavelength that is longer than the first peak wavelength and to generate the white light mixed with the second peak wavelength and the first peak wavelength. The mobile machine further includes a light detection and ranging (LIDAR) system configured to generate a second laser beam and manipulate the second laser beam to sense a spatial map of target objects in a remote distance.
