[0026] Embodiment 1:

[0027] In this embodiment, a liquid-cooled xenon lamp light source, as shown in Figure 1 and Figure 2 , comprises a shell 1 and a light source assembly, specifically, the shell 1 is sleeved on the light source assembly, the light source assembly comprises a xenon lamp 2, a cathode extension ring 3 and an anode extension ring 4, the cathode extension ring 3 and the anode extension ring 4 are respectively arranged at the cathode end and the anode end of the xenon lamp 2, the cathode extension ring 3 is sleeved with a cathode heat dissipation ring 5, the cathode heat dissipation ring 5 is used for a small amount of heat dissipation at the cathode end, the xenon lamp 2 and the anode extension ring 4 are sleeved with an anode heat dissipation ring 6, the anode heat dissipation ring 6 is used for a large amount of heat dissipation at the cathode end and the anode end, the anode heat dissipation ring 6 is internally provided with a hollow liquid cooling cavity 7, the anode heat dissipation ring 6 is provided with a liquid inlet joint 8 and a liquid outlet joint 9 at the end thereof, which are in communication with the liquid cooling cavity 7, and are used for circulating cooling liquid in the liquid cooling cavity 7 to quickly discharge heat.

[0028] With this structure, by arranging the liquid cooling cavity 7 capable of circulating cooling liquid in the anode heat dissipation ring 6, compared with the air-cooled xenon lamp 2, the bulky air-cooled fins are abandoned, so that the overall structure is smaller and more compact, the liquid cooling cavity 7 does not directly contact the xenon lamp 2, has strong insulation, improves safety, so that water or aqueous solution which is not insulated but has stronger heat conduction performance can also be used, and the heat conduction and heat dissipation efficiency is higher.

[0029] In this embodiment, as shown in Figure 1As shown, the outer shell 1 is a hollow structure with open ends. The inner wall of the outer shell 1 is divided into an anode heat dissipation cavity and a cathode heat dissipation cavity by an annular partition 10. The anode heat dissipation ring 6 is inserted into the anode heat dissipation cavity, and the cathode heat dissipation ring 5 is inserted into the cathode heat dissipation cavity. The structure is compact and easy to assemble.

[0030] As an optimized implementation of this embodiment, such as Figure 1 As shown, it also includes an insulating heat-conducting ring 11, which is sleeved on the outside of the xenon lamp 2. The two ends of the insulating heat-conducting ring 11 contact the cathode end and anode end of the xenon lamp 2, respectively. One end of the insulating heat-conducting ring 11 passes through the annular partition 10 and abuts against the cathode heat dissipation ring 5. The inner wall of the anode heat dissipation ring 6 has an annular groove 12 at one end facing the annular partition 10. The other end of the insulating heat-conducting ring 11 is inserted into the annular groove 12. The insulating heat-conducting ring 11 is spaced between the cathode extension ring 3 and the anode extension ring 4. The insulating effect of the insulating heat-conducting ring 11 prevents the anode extension ring 4 from connecting the cathode end and anode end of the xenon lamp 2, thus preventing accidental short circuits. The insulating heat-conducting ring 11 also plays a certain role in heat conduction, transferring some of the heat from the cathode heat dissipation ring 5 to the anode heat dissipation ring 6, which is then discharged by the coolant in the anode heat dissipation ring 6.

[0031] The aforementioned insulating and heat-conducting ring 11 is made of a high thermal conductivity insulating material, preferably ceramic, high thermal conductivity special insulating plastic, or any other solid material that can both conduct heat and provide insulation.

[0032] In this embodiment, the end face of the cathode extension ring 3 is embedded in the light-emitting surface of the cathode end of the xenon lamp 2, and the outer wall of the cathode extension ring 3 abuts against the inner wall of the cathode heat dissipation ring 5. The cathode extension ring 3 is used to indirectly transfer the heat from the cathode end of the xenon lamp 2 to the cathode heat dissipation ring 5, so that the cathode heat dissipation ring 5 is closer to the end and the heat dissipation is faster. At the same time, the cathode extension ring 3 also increases the heat dissipation area and further improves the heat dissipation efficiency.

[0033] Furthermore, it also includes a front baffle ring 13, which abuts against and seals the cathode heat dissipation ring 5. The front baffle ring 13 can be fixedly connected to the housing 1 by a fastening connector. The annular hole of the front baffle ring 13 is aligned with the light-emitting surface of the cathode end of the xenon lamp 2, so as not to affect the light intensity of the xenon lamp 2.

[0034] In this embodiment, as Figure 1As shown, the anode extension ring 4 covers the anode end of the xenon lamp 2, the outer wall of the anode extension ring 4 abuts against the inner wall of the anode heat dissipation ring 6, and the anode extension ring 4 increases the heat dissipation area from the end, so that the heat of the anode end is transmitted to the anode heat dissipation ring 6 through the anode extension ring 4, and as an optimization, the anode extension ring 4 is provided with a plurality of heat dissipation holes 14 for air cooling, thereby further improving the heat dissipation efficiency.

[0035] Further, the rear cover plate 15 is inserted into the anode heat dissipation cavity and abuts against the anode heat dissipation ring 6, the rear cover plate 15 is provided with the insertion hole 16 corresponding to the positions of the liquid inlet connector 8 and the liquid outlet connector 9, and the rear cover plate 15 is further provided with a plurality of through holes 17 corresponding to the positions of the heat dissipation holes 14, so as to keep the air flowing to improve the heat dissipation.

[0036] In the embodiment, the cathode terminal and the anode terminal are further included, the cathode terminal is electrically connected to the cathode extension ring 3, and the anode terminal is electrically connected to the anode extension ring 4, so that an external power supply can be connected to supply power to the xenon lamp 2, and specifically, the external power supply is a liquid-cooled electric control integrated box, the liquid-cooled electric control integrated box includes the electric control unit for power supply and the liquid cooling unit for water supply, the liquid cooling unit is in circulation communication with the liquid inlet connector 8 and the liquid outlet connector 9, and the electric control unit is electrically connected to the cathode terminal and the anode terminal, so as to realize integrated control of electricity and waterway, and the liquid-cooled electric control integrated box is a prior art, and its structure and functions will not be further described here.

[0037] In the embodiment, as shown, Figure 3 The universal support 18 is further included, one end of the universal support 18 is connected to the shell 1, and the universal support can freely adjust the direction of the liquid-cooled xenon lamp light source, so as to meet the use in different occasions, and preferably, the universal support is a universal metal hose or a universal ball head connected to the shell 1.

[0038] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
