The lamp panel 4 is fixedly provided with an air inlet pipe 402, the pipe wall of the connecting pipe 1 is provided with an adapting groove 102, and the adapting groove 102 is matched with the outer wall of the air inlet pipe 402. The connecting pipe 1 is internally and fixedly provided with a supporting ring 103, and the top of the supporting ring 103 is matched with one end, far away from the LED bulb 401, of the lamp panel 4. The adapting groove 102 not only enables the gas to smoothly enter the gas inlet pipe 402, but also ensures that the lamp panel 4 is quickly and correctly placed on the support ring 103 in the connecting pipe 1.

The exhaust fan 106 is fixedly arranged in the connecting pipe 1, the exhaust opening 105 is formed in the pipe wall of the connecting pipe 1, the exhaust opening 105 and the exhaust fan 106 are positioned on the same horizontal plane, the second pressure valve 404 is fixedly arranged in the exhaust opening 105, the second pressure valve 404 is a one-way valve, and the valve port can only be opened to the outer side of the connecting pipe 1. The second pressure valve 404 can be opened only in one direction, and foreign substances or dust are prevented from entering the connection pipe 1 through the air outlet 105. The second pressure valve 404 is opened outwards by the blowing of the exhaust fan 106, so that the hot air in the connecting pipe 1 is blown out of the connecting pipe 1, and the temperature in the connecting pipe 1 is reduced.

The lamp panel 4 is provided with a diversion hole 403 and a through hole 406, and the air inlet pipe 402 is communicated with the diversion hole 403. The first pressure valve 107 is fixedly arranged in the air inlet pipe 402, the first pressure valve 107 is a one-way valve, and the valve port can only be opened towards the direction of the flow dividing hole 403. When the gas pressure in the glass cover 3 and the connection pipe 1 is reduced, the first pressure valve 107 opens into the connection pipe 1, and gas is introduced into the glass cover 3 and the connection pipe 1 through the connection pipe 1 and the split hole 403. It is possible to prevent foreign substances or dust from entering the glass cover 3 or the connection pipe 1 through the air inlet holes, thereby preventing the foreign substances or dust from damaging the bulb.

The center line of the through hole 406 is located between the exhaust fan 106 and the exhaust port 105. When the second pressure valve 404 is opened outward by the exhaust fan 106, the air pressure above the through hole 406 is reduced due to the air flow of the exhaust fan 106, so that the air in the glass cover 3 gradually gathers above the through hole 406 and is blown out of the connection pipe 1 by the exhaust fan 106. And simultaneously, the temperature of the connecting pipe 1 and the glass cover 3 is reduced.

The wall of the flow dividing hole 403 far away from the air inlet pipe 402 is fixedly provided with a triangular bulge 405, and two inclined planes of the triangular bulge 405 incline towards the inside of the connecting pipe 1 and the inside of the glass cover 3 respectively.

After the glass cover 3 completes the connection with the connection pipe 1, the glass cover 3 extrudes the lamp panel 4, so that the first contact 104 is in close contact with the second contact, and the purpose of energizing the LED bulb 401 is achieved.

The one end that connecting pipe 1 kept away from glass cover 3 is fixed and is provided with mount pad 2, mount pad 2 is connected with first contact 104, exhaust fan 106 electricity. The lamp bulb is mounted on the lamp holder through the mounting seat 2, so that the power-on process of the exhaust fan 106 and the LED lamp bulb 401 can be completed.

Working principle: when in use, the air inlet pipe 402 on the lamp panel 4 is firstly opposite to the adapting groove 102, the second contact is made to face the connecting pipe 1, then the lamp panel 4 is placed in the connecting pipe 1, and the external thread 301 of the glass cover 3 is connected with the internal thread 101 of the connecting pipe 1.

Then, the bulb is integrally mounted on the corresponding lamp holder through the mounting seat 2, so that the exhaust fan 106 and the LED bulb 401 can be powered on. During use, the exhaust fan 106 is automatically turned on. The air flow blown out by the exhaust fan 106 opens the second pressure valve 404 to the outside of the connection pipe 1, and thereby the hot air in the connection pipe 1 is blown out of the connection pipe 1 through the exhaust port 105. The temperature in the connecting pipe 1 is prevented from rising, so that the LED bulb 401 cannot emit light normally.

At the same time, the air pressure above the through hole 406 is reduced due to the air flow of the exhaust fan 106, so that the air in the glass cover 3 gradually gathers above the through hole 406 and is blown out of the connection pipe 1 by the exhaust fan 106. At this time, the air pressure in the connecting pipe 1 and the glass cover 3 is reduced, so that the first pressure valve 107 is opened inwards, external cold air is further led to enter through the air inlet pipe 402, and after entering the flow dividing hole 403, the air entering through the air inlet pipe 402 is divided by the triangular protrusions 405, so that part of the air enters into the glass cover 3, and the other part of the air enters into the connecting pipe 1, thereby achieving the purpose of simultaneously cooling the glass cover 3 and the connecting pipe 1, and avoiding the phenomenon of fogging caused by overlarge temperature difference between the air temperature in the glass cover 3 and the outside.

By the cooperation of the first pressure valve 107 and the second pressure valve 404, the cooling of the connection pipe 1 and the glass cover 3 can be completed at the same time. The LED bulb 401 is prevented from being in a high-temperature environment while the excessive temperature difference between the inside and the outside of the glass cover 3 is prevented from being fogged, and dust and impurities are effectively prevented from entering the glass cover 3 or the connecting pipe 1 when the bulb is not used, so that the damage of the impurities or the dust to the bulb is reduced.

Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
