[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] The laser fish attracting lamp system using Ce:LUAG fluorescent conversion material includes: a laser lighting system, a 10-1000mm transmission optical fiber, and a fluorescent conversion system. The laser optical fiber system is provided with a laser outlet, the coupler has a light inlet and a light outlet, and the fluorescent conversion system has a light inlet; the laser outlet of the laser lighting system is docked with the light access port of the coupler, the 10-1000mm transmission optical fiber is docked with the light outlet of the coupler, the other end of the optical fiber is docked with the FC connector at the light inlet of the fluorescent conversion system, the FC connector is docked with the FC optical fiber coupler, and the fluorescent ceramic rod is docked with the light outlet of the FC optical fiber coupler through a thread; the laser lighting system can emit a blue laser light source, which enters the optical fiber through the coupler and is transmitted to the fluorescent conversion system. Furthermore, the 10-1000mm transmission optical fiber can also be provided with a winder. The laser lighting system has a wire access end that can be connected to an external power supply; the external power supply can adjust the power of the laser brightness emitted by the laser lighting system, and the power is adjusted by controlling the current size of the external power supply. The fluorescent conversion system includes: an anti-collision cage, a fixture, an FC optical fiber coupler, and a rod-shaped fluorescent ceramic.

[0029] There is a raised cylindrical channel on the anti-collision cage, and the fixture is welded on the other side of the raised cylindrical channel. There is a fixing frame inside the anti-collision cage; there is an optical access port on the left side of the connector, and there is an FC connector at the optical access port to fix the optical fiber. After fixation, the FC connector is docked with the FC fiber coupler, and there is a threaded light outlet on the right side of the FC fiber coupler; a threaded docking port is provided at one end of the rod-shaped fluorescent ceramic.

[0030] The raised cylindrical channel on the anti-collision cage has a fixture welded on the channel, one end of which serves as the entrance for the 10-1000mm optical fiber and the other as the fixing point for the FC optical fiber coupler.

[0031] One end of the fixture is welded to one side of the protruding cylindrical channel, and the other side of the fixture fixes the FC optical fiber coupler at a position in the same straight line as the hollow cylinder.

[0032] The raised cylindrical channel is a hollow cylinder; the 10-1000mm optical fiber enters the anti-collision cage through the hollow cylinder and connects with the FC connector on the other side of the hollow cylinder, and the FC connector and the light inlet of the FC fiber coupler are connected; thereby, the 440nm-460nm blue light laser emitted by the laser illumination system is irradiated into the FC fiber coupler of the anti-collision cage.

[0033] There is a groove thread on the right side of the FC fiber coupler, and there is also a connecting thread on one side of the rod-shaped fluorescent ceramic that has been processed. After the threads are connected, the 440nm-460nm laser inside the connector is incident on the inside of the rod-shaped fluorescent ceramic through the threaded light outlet.

[0034] By grinding the rod-shaped fluorescent ceramic, cylindrical threads and inclined cross-section threads appear.

[0035] The cylindrical thread corresponds to a direct-type fish attracting lamp, and the laser is directly emitted into the fluorescent conversion material doped with 0-9.9% Ce:LuAG through the connector thread light outlet.

[0036] The inclined cross-section thread corresponds to the reflective fish attracting lamp. The laser is incident on the inclined cross-section through the connector thread light outlet, and then enters the fluorescent conversion material through the refraction of light. According to the law of refraction: n1sinθ1=n2sinθ2, it can be seen that the section angle is related to the refractive index of the incident surface medium. The section angle range is 0-arctan (1.33 / 1.256), and the refractive index range is 0-1.33.

[0037] Rod-shaped fluorescent ceramics can use uniform doping and gradient doping.

[0038] The length of the ceramic rod uniformly doped with Ce: LuAG fluorescent conversion material is selected according to the Lambert-Beer law:

[0039] I(x)=I0e -ax .

[0040] Ce in Gradient Doped Ce:LuAG Fluorescence Conversion Material Ceramic Rod 3+ The doping concentration is also determined according to the Lambert-Beer law. At this time, the specific length of each section of the fluorescent ceramic rod is limited to 2 cm, and the total length of the ceramic rod is 10 cm. Gradient doping can effectively improve the optical efficiency, make the heat distribution uniform, enhance the stability and service life of the device, and is suitable for high-power laser light sources.

[0041] The high-power laser fish attracting lamp provided by the present invention includes a laser lighting system, a coupler, a 0-1000mm optical fiber and a fluorescence conversion system. The laser lighting system is provided with a light outlet, the coupler has a light inlet and a light outlet, the 10-1000mm optical fiber has a winder, the fluorescence conversion system has a light inlet, and there is an FC connector at the light inlet. The laser light outlet is docked with the light inlet of the coupler, the light outlet of the coupler is docked with the optical fiber, the other end of the optical fiber is docked with the FC connector of the light inlet of the fluorescence conversion system, the FC connector is then docked with the light inlet of the FC optical fiber coupler, and the fluorescent ceramic rod is docked with the light outlet of the FC optical fiber coupler by twisting the thread; the laser lighting system emits a blue laser, which enters the optical fiber through the coupler and is transmitted to the fluorescence conversion system.

[0042] As an implementation method, the laser illumination system is externally connected to a power supply; the power supply can control the generated laser power.

[0043] As an implementation mode, the external power supply is connected to the laser lighting system via a cable.

[0044] As an implementation method, the coupler couples the laser illumination system with the optical fiber, connecting the laser in the laser illumination system to the optical fiber.

[0045] As an implementation method, there is a light inlet in the fluorescence conversion system, the optical fiber is connected to the FC connector of the light inlet, the FC connector is connected to the FC fiber coupler, and the rod-shaped fluorescent ceramic is connected to the light outlet of the FC fiber coupler through a thread, and finally the laser is irradiated onto the Ce:LUAG-doped fluorescence conversion material.

[0046] The process of preparing Ce: LuAG fluorescent ceramics first involves the selection and preparation of raw materials. Usually, stable oxides are selected as the matrix, and Ce: LuAG with a doping concentration of 0-9.9% is used as the dopant. Then, the powder is prepared by solid phase reaction method, and Ce: LuAG and stable oxide powder (such as Al2O3) are ball milled to mix the raw powders evenly. Then, molding is carried out, usually by pressing, and the evenly mixed powder is poured into a cylindrical mold with a diameter of 10 cm. The formed ceramic body needs to be dried at a temperature of 80°-120° to remove moisture and prevent moisture evaporation from causing the body to dry and crack. Next, the sintering process is carried out. The powder particles are bonded together by high-temperature sintering to form a dense round rod-shaped fluorescent ceramic. The sintering temperature is generally selected between 1000°-1800°. Finally, heat treatment (1000°-1600°) and annealing (800°-1200°) are carried out after sintering to optimize the microstructure of the material and further improve the performance of the ceramic.
