[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1-6 As shown, an LED lighting device with a heat dissipation function includes a lampshade 1 and a mounting hole 2. The mounting hole 2 is opened on the inner side of the lampshade 1. The lampshade 1 is connected to the building through the mounting hole 2 to maintain the stability of the lampshade 1. The inner top wall of the lampshade 1 is installed with an LED light source body 3. The inner top wall of the lampshade 1 is also installed with a temperature detector 17, a wireless controller 4 and a power controller 5. The temperature inside the lampshade 1 is detected by the temperature detector 17, and the external control instructions are received by the wireless controller 4 to adjust the brightness and color temperature of the light source. The input voltage is adjusted by the power controller 5 to meet the requirements of the LED light source body 3 for using a suitable voltage.

[0025] A slide groove 6 is provided on one side of the lampshade 1 , and a filter screen 7 is slidably contacted on the inner wall of the slide groove 6 . The filter screen 7 filters the air entering the lampshade 1 and blocks the dust contained in the air from entering the lampshade 1 .

[0026] The other side of the lampshade 1 is connected to an exhaust duct 9, and the lampshade 1 is connected to the outside through the duct. A fan 10 is provided inside the exhaust duct 9, and the fan 10 is used as a power source to provide power for the air inside the lampshade 1 to flow to the outside.

[0027] The inner wall of the exhaust duct 9 is rotatably connected to a baffle 11, which closes the air outlet of the exhaust duct 9 to prevent external dust from entering the interior of the lampshade 1 through the exhaust duct 9. There are two baffles 11, and the two baffles 11 are arranged up and down. One side of one baffle 11 is connected to magnet 12, and one side of the other baffle 11 is connected to magnet 2 13. After the temperature inside the lampshade 1 reaches the normal temperature, the baffle 11 loses the aerodynamic force and the baffle 11 hangs down in a vertical state. After hanging down, magnet 12 and magnet 2 13 are adsorbed together to maintain the stability of the baffle 11.

[0028] The two baffles 11 are connected with a plurality of guide plates 14, and the plurality of guide plates 14 have an inclined angle. When the air inside the lampshade 1 is flowing to the outside, the baffle 11 receives the power of the air flow through the guide plate 14, so that the baffle 11 is always in an open state, facilitating the air inside the lampshade 1 to flow to the outside.

[0029] The inner wall of the air exhaust duct 9 is connected with a rack 15, and the fan 10 is installed in the inside of the rack 15, which supports the fan 10 and maintains the stability of the fan 10.

[0030] The air exhaust duct 9 is connected with a flow collector 16 on one side inside the lampshade 1, and the flow collector 16 has an inclined angle. The flow collector 16 collects the air inside the lampshade 1 flowing to the outside, facilitating the air inside the lampshade 1 to flow to the outside.

[0031] The inside of the filter screen 7 is provided with a positioning mechanism 8, which maintains the stability of the filter screen 7. The positioning mechanism 8 includes a rotating shaft 801, which is rotatably connected with the inner wall of the filter screen 7. The outer surface of the rotating shaft 801 is rotatably connected with a clamping jaw 802. One side of the clamping jaw 802 is connected with a spring 804, and the other end of the spring 804 is connected with the inner wall of the filter screen 7. The rotating shaft 801 supports the clamping jaw 802, so that the clamping jaw 802 has a rotating function. The clamping jaw 802 is separated from the contact with the clamping groove 803 by rotating, which limits the positioning of the filter screen 7. The spring 804 is compressed while the clamping jaw 802 rotates downward, and the compressed spring 804 provides power for the reset of the clamping jaw 802. The inner side of the lampshade 1 is provided with a clamping groove 803, and the inner wall of the clamping groove 803 is in contact with one end of the clamping jaw 802. The clamping groove 803 blocks the clamping jaw 802 and limits the movement position of the clamping jaw 802 by contacting with the clamping jaw 802. The clamping jaw 802 limits the movement position of the filter screen through the rotating shaft 801, thereby improving the stability of the filter screen 7.

[0032] It should be noted that in actual use, after the temperature detector 17 detects that the temperature of the LED light source body 3 is too high, the fan 10 is started to rotate. After the fan 10 rotates, the air inside the lampshade 1 flows to the outside, and the flowing air contacts with the guide plate 14, which blows the guide plate 14 to move position. The guide plate 14 drives the baffle 11 to move position, and the air inside the lampshade 1 can flow to the outside without obstruction after the air outlet of the air exhaust duct 9 is opened.

[0033] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
