[0022] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The illustrations only show structures related to the present disclosure and are not drawn according to the number, shape and size of structures in actual implementation. In actual implementation, the form, quantity and proportion of each structure may be changed at will, and its structural layout may also be more complex.

[0023] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples. However, one skilled in the art will appreciate that the aspects described can be practiced without these specific details.

[0024] See also Figure 1 A cooling system for a stage light includes: a chip assembly 20; a radiator 50, which serves as a cold source and can provide cooling water or cooling oil to the pipeline. The radiator 50 is connected to the chip assembly 20 via a cooling pipeline 30, and the cooling pipeline 30 is provided with a power source 60; a wavelength conversion assembly 10, one end of the wavelength conversion assembly 10 is connected to the chip assembly 20 via a first return pipeline 40, and the other end is connected to the radiator 50 via a second return pipeline 70.

[0025] The power source 60 can be a pump, such as a peristaltic pump, which delivers a coolant, such as cooling water or cooling oil, to the cooling line 30. Furthermore, because the cooling line 30, the first return line 40, and the second return line 70 form a circulation line, the cooling water or cooling oil can cool the chip and the wavelength conversion material layer.

[0026] Furthermore, the chip assembly 20 includes a chip 21 and a second cooling cavity 22. The chip 21 is placed in the second cooling cavity 22. The second cooling cavity 22 is a closed structure. In this application, the chip is mainly used to control the laser intensity, irradiation time, etc. irradiated to the wavelength conversion material.

[0027] Furthermore, the wavelength conversion component 10 includes a wavelength conversion material layer 11, a first cooling cavity 12 and a condenser 13. The condenser 13 is arranged above the wavelength conversion material layer 11, and the wavelength conversion material layer 11 is placed in the first cooling cavity 12, that is, the first cooling cavity 12 seals the wavelength conversion material layer. The first return line 40 or the second return line 70 is connected to the first cooling cavity 12. The first cooling cavity 12 is made of an optically transparent material so that the light beam converged by the condenser 13 can be irradiated onto the wavelength conversion material. In the present application, the wavelength conversion material in the wavelength conversion material layer 11 can be fluorescent powder, phosphor powder or quantum dots, etc. The condenser 13 can converge the excitation light so that the light energy incident on the wavelength conversion material can meet the excitation requirements.

[0028] During operation, the pump is activated to transport the cooling water or oil from the radiator through the cooling pipe to the second cooling chamber to cool the chip. The cooling water or oil then enters the first return pipe and, under the action of the pump, enters the first cooling chamber to cool the wavelength conversion material. Finally, the used cooling water or oil returns to the radiator, completing the entire cooling cycle. The flow rate of the cooling water or oil can be adjusted by adjusting the pump speed to achieve the desired cooling effect.

[0029] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
