Referring to fig. 1, fig. 1 is a schematic frame diagram of a first embodiment of the lighting device of the present application. The lighting device 10 of the present embodiment may be applied to a laser lighting fixture, for example, the laser lighting fixture includes a searchlight or a beam lamp. Therein, the illumination device 10 includes a light source assembly 11, a wavelength conversion assembly 12, a first collecting lens assembly 14, and an electrically controlled diffuser 15.
The excitation light emitted by the light source assembly 11 includes blue light, violet light, green light, ultraviolet light or other types of light; for example, the light source module 11 includes blue semiconductor laser diodes, the blue laser beam emitted from the light source module 11 is used as excitation light, the number of the blue semiconductor laser diodes in the light source module 11 may be one or more, and specifically may be set according to the brightness requirement of the lighting device 10, where the plurality of blue semiconductor laser diodes may be arranged in an array.
The wavelength conversion component 12 is disposed on an optical path of the excitation light, and is configured to convert at least part of the excitation light into stimulated light. The wavelength conversion component 12 is located on the light emitting side of the light source component 11, and is configured to convert at least part of excitation light emitted by the light source component 11 into stimulated light; the wavelength conversion component 12 may be referred to as a wavelength conversion element.
It should be noted that excitation light and excited light are relative concepts; the excitation light is capable of exciting the wavelength conversion material layer within the wavelength conversion component 12 such that the wavelength conversion material layer generates light of different wavelengths; lased light is light generated by excitation of a wavelength conversion material layer within the wavelength conversion component 12 by excitation light.
The excitation light and the received laser light are located on the same side of the wavelength conversion assembly 12, that is, the side of the excitation light emitted from the light source assembly 11 entering the wavelength conversion assembly 12 is the same as the side of the wavelength conversion assembly 12 emitting the received laser light.

Therefore, the unconverted excitation light and the laser beam traveling in the direction toward the reflecting structure are reflected by the reflecting structure and are emitted through the light incident side of the wavelength conversion device (i.e., the side on which the excitation light is incident). In these embodiments, the reflecting structure reflects unconverted excitation light into the wavelength conversion component 12 again, and this part of the excitation light is likely to be converted into stimulated light by the wavelength conversion component 12 after being reflected, and therefore, a desired conversion efficiency can be obtained by the wavelength conversion component 12 having a relatively small thickness.

Wherein the first collecting lens assembly 14 is disposed at the light emitting side of the wavelength conversion assembly 12.
The first collecting lens assembly 14 is used for collecting the stimulated light emitted by the wavelength conversion assembly 12 to reduce the divergence angle of the stimulated light. Since the divergence angle of the stimulated light emitted from the wavelength conversion assembly 12 is large, for example, the divergence angle of the stimulated light emitted from the wavelength conversion assembly 12 is 120 ° to 160 °, the first collecting lens assembly 14 reduces the divergence angle of the stimulated light to 60 ° to 80 ° so as to be effectively utilized by other elements of the lighting device 10, and reduce light loss. The first collection lens assembly 14 may be a convex lens or a meniscus lens, or the first collection lens assembly 14 may also include a plurality of convex lenses arranged in a stack.
The electrically controlled scattering member 15 is used for scattering the excitation light emitted by the light source assembly 11 and/or the received laser light emitted by the first collecting lens assembly 14, and the electrically controlled scattering member 15 adjusts a divergence angle of the excitation light and/or the received laser light passing through the electrically controlled scattering member 15 through an applied voltage, that is, the divergence angle of the excitation light and/or the received laser light passing through the electrically controlled scattering member 15 is changed based on the applied voltage of the electrically controlled scattering member 15, so as to further perform the scattering treatment; the applied voltage is the voltage applied to the electrically controlled scattering element 15.
Automatically controlled scattering piece 15 can set up in the light-emitting side of light source subassembly 11, and automatically controlled scattering piece 15 is used for carrying out the scattering to the exciting light of light source subassembly 11 outgoing to adjust the angle of divergence of the exciting light of light source subassembly 11 outgoing.
