Description

Technical Field

[0001] The utility model relates to the technical field of medical lighting, in particular to a temperature reduction protection device for xenon lamp lighting. Background Art

[0002] Xenon lamps are electric light sources that generate light through the discharge of high- or ultra-high-pressure xenon gas. Because their spectral energy distribution is similar to that of the sun and their color temperature is approximately 6000K, they are widely used in applications requiring the simulation of natural sunlight. The spectral distribution of the continuous spectrum of xenon lamps is virtually independent of changes in lamp input power, and the spectral energy distribution varies little over the lamp's lifetime, making them extremely valuable in scientific research and industrial applications. Xenon lamps boast high luminous efficacy, stable color temperature, fast startup, and a long service life. They are commonly used in film projection, medical equipment, industrial testing, and other fields. When xenon lamps are used in medical equipment, the lamp illuminates one end of an optical fiber, and the light is output at the other end to the desired location. However, in actual use, the high temperature of the xenon lamp's focal point, far exceeding the temperature that the optical fiber can withstand, can easily damage the fiber over extended periods of use.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] A cooling protection device for xenon lamp lighting, this embodiment, as Figure 1-4 As shown, it includes a fixed base 1, both ends of the fixed base 1 are provided with positioning slots 2, and the inner wall of the positioning slot 2 is clamped and installed with a xenon lamp 3, an outer wall of one side of the fixed base 1 is fixed with an air guide shell 4 by screws, and the air guide shell 4 is plugged and fixed to the inner wall of the protective light box 7, the top outer wall of the protective light box 7 is hinged with a sealed box cover 8, and a conical focusing cover 9 is plugged and installed on the side of the fixed base 1 away from the air guide shell 4, the bottom axis of the conical focusing cover 9 is connected with a connecting pipe 10, and the outer wall of the connecting pipe 10 is plugged with a cylindrical inner shell 12 whose axis is connected to the fixed sleeve 11 at both ends, the inner wall of the cylindrical inner shell 12 away from the connecting pipe 10 is plugged with an optical fiber pipeline 13, and a focusing lens 14 is bonded and fixed to the middle part of the inner wall of the cylindrical inner shell 12, and the inner walls of the fixed sleeves 11 on both sides of the cylindrical inner shell 12 are clamped and fixed with circular heat insulation sheets 15;

[0024] By setting a protective lamp box 7 outside the xenon lamp 3 and using a relatively closed space, a fan is used at the end to blow external cold air directly to the inner wall of the protective lamp box 7, thereby accelerating the air flow rate around the xenon lamp 3, which can speed up the cooling process of the xenon lamp 3 and thus play a certain role in heat dissipation protection.

[0025] The bottom and surrounding outer walls of the air guide housing 4 are provided with air inlet slots 5 distributed at equal distances, and an exhaust fan 6 is installed on the inner wall of the end of the air guide housing 4. The middle outer wall of the fixed sleeve 11 is provided with an annular groove 16, and the outer wall of the annular groove 16 is fixed with a fixing clamp 17 by screws. The fixing clamp 17 is tightly fitted with the connecting pipe 10 and the optical fiber pipeline 13;

[0026] A cylindrical outer shell 18 is welded to the outer wall of the cylindrical inner tank 12, and an inner wall at one end of the cylindrical outer shell 18 is connected to a water inlet pipe 20, and the bottom of the inner wall at the other end of the cylindrical outer shell 18 is connected to a drain pipe 21. The direction of water flow inside the cylindrical outer shell 18 is opposite to the direction of light.

[0027] The inner wall of the cylindrical shell 18 is embedded with semiconductor cooling sheets 19 distributed at equal distances, and the heat absorbing surface of the semiconductor cooling sheets 19 faces the cylindrical inner container 12;

[0028] During the irradiation of the xenon lamp 3, the high-temperature optical fiber is passed through the double-layer circular thermal insulation sheet 15, thereby achieving double thermal insulation treatment without affecting the brightness, thereby reducing the impact of high-temperature light on the optical fiber pipeline, and during the thermal insulation and cooling treatment, the reverse flow of cooling cold water is also used, and the high specific heat capacity of cold water is utilized, so that the high-temperature light can be further cooled, thereby effectively reducing the impact on the optical fiber pipeline.

[0029] When using this embodiment, the air guide housing 4 is first fixedly installed on the fixed base 1, and the exhaust fan 6 is installed at the end of the air guide housing 4. Then, the xenon lamp 3 is installed on the fixed base 1, and the remaining components of the cooling protection device are assembled. The water inlet pipe 20 is connected to the outside of the water pump to pump cold water, and the space between the cylindrical inner liner 12 and the cylindrical outer shell 18 is filled with cold water. Then, the xenon lamp 3 is started. After the xenon lamp 3 irradiates, the light is concentrated by the conical focusing cover 9, so that the light passes through the inside of the connecting pipe 10, so that the high-temperature light passes through the circular heat insulation sheet 15, which can play a certain heat insulation role and enter the cylindrical inner liner 12. The internal light can be further cooled due to the effect of the semiconductor refrigeration plate 19 and the counter-flowing cold water, and the focusing lens 14 will focus the scattered light and hit the optical fiber pipe 13. Before being projected onto the optical fiber pipe 13, it also passes through another circular heat insulation plate 15 for further heat insulation. Multiple cooling and heat insulation can effectively reduce the impact of high temperature on the optical fiber pipe 13, and in order to further reduce the temperature of the xenon lamp 3 and cool the semiconductor refrigeration plate 19, the air intake fan 23 is started to accelerate the air circulation inside the protective light box 7, thereby further cooling and protecting it.
