Title:
MULTI-FUNCTIONAL AND MULTI-PURPOSE PORTABLE LASER ILLUMINATION SYSTEM AND LASER FLASHLIGHT
Document Type and Number:
WIPO Patent Application WO/2021/017375
Kind Code:
A1
Abstract:
A multi-functional and multi-purpose portable laser illumination system and laser flashlight. Said illumination system comprises a first optical system (200) and a second optical system (300); a laser device (201) for emitting excitation light and a wavelength conversion apparatus (203) for absorbing a part of the excitation light to form excited light are provided in the first optical system (200) or the second optical system (300); the second optical system (300) is provided at the outermost part in the light emission direction; a relative displacement or a relative separation may occur between the first optical system (200) and the second optical system (300); when a displacement or separation does not occur between the two optical systems (200, 300), the excited light and the excitation light which is not absorbed by the wavelength conversion apparatus (203) are synthesized to form illumination light, and the illumination light is emitted by the second optical system (300); and when a relative displacement or separation occurs between the two optical systems (200, 300), the excitation light emitted by the laser device is (201) emitted from the first optical system (200). By means of the relative displacement or the relative separation between the two optical systems (200, 300), free switching of the functions of emitting illumination light or excitation light by the illumination system can be implemented, which can not only achieve high-efficiency ultra-far-distance illumination, but can also achieve ultra-far-distance help calling or fire making.
