For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] Embodiment 1: In this embodiment, a liquid-cooled xenon lamp light source, as shown in Figure 1 and Figure 2 includes a shell 1 and a light source assembly, specifically, the shell 1 is sleeved on the light source assembly, the light source assembly includes 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, the anode heat dissipation ring 6 is internally provided with a hollow liquid cooling cavity 7, and the anode heat dissipation ring 6 is provided with a liquid inlet connector 8 and a liquid outlet connector 9 in communication with the liquid cooling cavity 7, for circulating cooling liquid in the liquid cooling cavity 7 to quickly dissipate heat.

[0023] 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 with stronger heat conduction performance but not insulation can also be used, and the heat conduction and heat dissipation efficiency is higher.

[0024] In this embodiment, as shown in Figure 1As shown, the above-mentioned shell 1 is a hollow structural member with open ends. The inner wall of the above-mentioned shell 1 is divided into an anode heat dissipation cavity and a cathode heat dissipation cavity by an annular partition 10. The above-mentioned anode heat dissipation ring 6 is plugged into the above-mentioned anode heat dissipation cavity, and the above-mentioned cathode heat dissipation ring 5 is plugged into the above-mentioned cathode heat dissipation cavity. The structure is compact and easy to assemble.

[0025] As an optimized implementation of this embodiment, Figure 1 As shown, it also includes an insulating heat-conducting ring 11, which is sleeved on the outside of the xenon lamp 2, and the two ends of the insulating heat-conducting ring 11 are respectively in contact with the cathode end and the anode end of the xenon lamp 2, wherein one end of the insulating heat-conducting ring 11 passes through the annular partition 10 and abuts against the cathode heat dissipation ring 5, and the inner wall of the anode heat dissipation ring 6 facing the end of the annular partition 10 is provided with an annular groove 12, and the other end of the insulating heat-conducting ring 11 is fitted and inserted into the annular groove 12, and is connected between the cathode extension ring 3 and the anode extension ring 4 at intervals through the insulating heat-conducting ring 11. The insulating effect of the insulating heat-conducting ring 11 prevents the anode extension ring 4 from connecting to the cathode end and the anode end of the xenon lamp 2, thereby preventing accidental short circuit. The insulating heat-conducting ring 11 also plays a certain heat-conducting role, which can transfer part of the heat of the cathode heat dissipation ring 5 to the anode heat dissipation ring 6, and then be discharged by the coolant in the anode heat dissipation ring 6.

[0026] The insulating heat-conducting ring 11 is made of a high thermal conductivity insulating material, preferably a ceramic material or a high thermal conductivity special insulating plastic or any other solid material that is both highly thermally conductive and insulating.

[0027] 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 the inner wall of the cathode heat dissipation ring 5. The cathode extension ring 3 is used to indirectly transfer the heat of 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 dissipates heat faster. At the same time, the cathode extension ring 3 also increases the heat dissipation area, further improving the heat dissipation efficiency.

[0028] Furthermore, it also includes a front blocking ring 13, which presses against and seals the cathode heat dissipation ring 5. The front blocking ring 13 can be fixedly connected to the outer shell 1 by a fastening connector. The ring hole of the front blocking ring 13 is aligned with the luminous surface of the cathode end of the xenon lamp 2, and does not affect the luminous intensity of the xenon lamp 2.

[0029] In this embodiment, Figure 1As shown, the anode extension ring 4 is covered on the anode end of the xenon lamp 2, and the outer wall of the anode extension ring 4 abuts the inner wall of the anode heat dissipation ring 6. The anode extension ring 4 increases the heat dissipation area from the end, so that the heat at the end of the anode is transferred to the anode heat dissipation ring 6 through the anode extension ring 4. As an optimization, a plurality of heat dissipation holes 14 are provided on the anode extension cover, which utilizes air heat dissipation to further improve the heat dissipation efficiency.

[0030] Furthermore, it also includes a rear cover 15, which is inserted into the anode heat dissipation cavity and pressed against the anode heat dissipation ring 6. The rear cover 15 is provided with a socket 16 corresponding to the position of the liquid inlet connector 8 and the liquid outlet connector 9. The rear cover 15 is also provided with a plurality of through holes 17 corresponding to the position of the heat dissipation holes 14, so as to maintain air circulation to improve heat dissipation.

[0031] In this embodiment, it also includes a cathode terminal and an anode terminal. 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 used to power the xenon lamp 2. Specifically, the external power supply is a liquid-cooled and electrically controlled integrated box. The liquid-cooled and electrically controlled integrated box includes an electrical control unit for power supply and a liquid cooling unit for water supply. The liquid cooling unit is cyclically connected to the liquid inlet connector 8 and the liquid outlet connector 9. The electrical control unit is electrically connected to the cathode terminal and the anode terminal, thereby realizing integrated electrical and water control. The liquid-cooled and electrically controlled integrated box is a prior art, and its structure and distance will not be further described here.

[0032] In this embodiment, Figure 3 As shown, it also includes a universal bracket 18, one end of which is connected to the housing 1. The universal bracket can freely adjust the direction of the liquid-cooled xenon lamp light source to meet the needs of different occasions. It is preferably connected to the housing 1 with a universal metal hose or a universal ball head.
