Embodiment Construction
[0024] Embodiments of the present invention will be described in detail below with reference to the drawings and implementation methods. It should be emphasized that all dimensions in the drawings are only schematic and not necessarily shown in true scale, and thus are not limiting. In addition, the combinations of modules in the embodiments of the present invention are only used to illustrate the spirit of the present invention, rather than to limit the specific scope of the present invention.
[0025]In order to obtain high-brightness illumination, the present invention adopts a laser light source capable of generating high power density as the excitation light source, and on this basis, adopts a light conversion element whose material structure is single crystal or transparent ceramic to convert the wavelength of the laser excitation light, thereby While obtaining high-brightness laser light, it ensures good heat conduction and heat dissipation performance of the wavelength...
