When the air pressure at the elastic rubber sheet 9 is less than the elasticity of the elastic rubber sheet 9, the air inlet 10 can be sealed through the first sealing column 11. When the air pressure at the elastic rubber sheet 9 is greater than the elasticity of the elastic rubber sheet 9, the elastic rubber sheet 9 is deformed by the air pressure, and a gap is generated between the first sealing column 11 and the air inlet 10. At this time, the air in the vertical pipe 5 can enter the arc tube 7 through the gap between the first sealing column 11 and the air inlet 10, and then through the elastic rubber sheet 9, the air inlet 10 and the first sealing column 11, the air intake amount entering each arc tube 7 can be made the same. The surface of the first sealing column 11 and the left and right sides of the inner wall of the vertical pipe 5 are fixedly connected with a connecting block 12, and the interior of the arc tube 7 is fixedly connected with a partition plate 13. The partition plate 13 is located in the middle of the arc tube 7, and the arc tube 7 is divided into left and right parts by the partition plate 13.

[0029] Embodiment 2:

[0030] Reference Figure 1-6The upper surface of the micro fan 4 is fixedly connected with a dustproof net 14, the surface of the arc tube 7 is sleeved with an elastic rubber sleeve 15, and a second air outlet 16 is opened on the side of the elastic rubber sleeve 15 close to the bulb body 1, and a second sealing column 17 is fitted on the inner wall of the second air outlet 16, and one end of the second sealing column 17 is fixedly connected to the inner wall of the arc tube 7. The second sealing column 17 is located in the middle of the first air outlet 8, and the diameter of the first air outlet 8 is larger than the diameter of the second sealing column 17. 5. The cooperation of the second air outlet 16 and the second sealing column 17 enables the first air outlet 8 to be automatically closed when the micro fan 4 is closed, and prevents dust from entering the arc tube 7 and the vertical tube 5 through the first air outlet 8. At the same time, the dustproof net 14 can prevent dust from entering the vertical tube 5 and the arc tube 7 through the micro fan 4. Further, the cooperation of the dustproof net 14, the elastic rubber sleeve 15, the second air outlet 16 and the second sealing column 17 can prevent dust from entering and accumulating in the vertical tube 5 or the arc tube 7.

[0031] In the utility model, when the user uses the high-power bulb lamp, the user turns on the micro-blower 4 to blow the air in the box body 2 into the vertical tube 5, and increases the air pressure at the elastic rubber sheet 9. When the air pressure at the elastic rubber sheet 9 is greater than the elasticity of the elastic rubber sheet 9, a gap is generated between the air inlet 10 and the first sealing column 11 by the air pressure, and the air in the vertical tube 5 enters the arc tube 7 through the gap between the air inlet 10 and the first sealing column 11. When the air pressure at the first air outlet 8 is greater than the elasticity of the elastic rubber sleeve 15, a gap is generated between the second air outlet 16 and the second sealing column 17 by the air pressure, and the air in the arc tube 7 is discharged through the second air outlet 16. At this time, the air discharged through the second air outlet 16 accelerates the air flow rate around the radiator 104, and the heat of the radiator 104 can be quickly dissipated.
