[0021] Example 1:

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4This invention discloses a self-cleaning LED flat panel light, comprising a lamp body 1 and a light-transmitting plate 2 disposed on the light-emitting side of the lamp body 1. The light-transmitting plate 2 is provided with a self-cleaning device for automatically cleaning the light-transmitting plate 2. The self-cleaning device includes a self-cleaning lampshade 3 detachably connected to the lamp body 1. The self-cleaning lampshade 3 is provided with a light-transmitting window 31 that cooperates with the light-transmitting plate 2. The light-transmitting plate 2 is disposed at the light-transmitting window 31. A transverse support plate 4 is provided horizontally inside the self-cleaning lampshade 3, and the transverse support plate 4 is disposed between the light-transmitting plate 2 and the lamp body 1. The self-cleaning lampshade 3 is disc-shaped. A first drive motor 5, capable of driving the self-cleaning lampshade 3 to rotate, is mounted on the horizontal support plate 4. The rotation shaft of the first drive motor 5 is fixedly connected to the center of the self-cleaning lampshade 3. An outer horizontal shell 6, corresponding to the horizontal support plate 4, is located on the side of the self-cleaning lampshade 3 away from the horizontal support plate 4. A light-transmitting plate 2 is disposed between the outer horizontal shell 6 and the horizontal support plate 4. A brush mechanism, capable of contacting and cooperating with the surface of the light-transmitting plate 2, is located on the side of the outer horizontal shell 6 near the light-transmitting plate 2. In this embodiment, by setting a self-cleaning device on the lamp body 1, the first drive motor 5 of the self-cleaning device can drive the disc-shaped self-cleaning lampshade 3 to rotate. During the rotation of the self-cleaning lampshade 3, it can cooperate with the brush mechanism to automatically wipe and clean the lower surface of the self-cleaning lampshade 3, improving the surface cleanliness of the self-cleaning lampshade 3. Automatic cleaning makes it more intelligent, more aesthetically pleasing, and requires no manual wiping, making it more intelligent and convenient to use.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The brush mechanism includes a transmission box 71 horizontally disposed within the outer transverse housing 6 and a second drive motor 72 disposed at one end of the transmission box 71 and connected to the input end of the transmission box 71. The transmission box 71 has several output shafts 73 on the side near the light-transmitting plate 2, and each output shaft 73 is equipped with a cleaning brush 74 that can contact and cooperate with the surface of the light-transmitting plate 2. The transmission box 71 drives the cleaning brush 74 to rotate actively, cooperating with the self-cleaning lampshade 3 and the first drive motor 5 to improve the cleaning effect.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaning brush 74 is disc-shaped, and the output shaft 73 is fixedly connected to a non-central position on the lower end face of the cleaning brush 74. Driving the cleaning brush 74 to rotate eccentrically improves the cleaning effect and enhances the cleaning quality.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4The lower end face of the horizontal support plate 4 is provided with two scrapers 8 that can contact and cooperate with the upper end face of the light-transmitting plate 2. The upper end face of the scraper 8 is fixedly connected to the horizontal support plate 4, and the contact surface between the lower end face of the scraper 8 and the light-transmitting plate 2 is a flexible surface. The scraper 8, in conjunction with the first drive motor 5, can scrape the upper end face of the light-transmitting plate 2 during its rotation, removing dust and improving the cleaning of the upper end face of the light-transmitting plate 2.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The light-transmitting plate 2 has several perforated dust collection grooves 21 at its center, which can cooperate with the scraper 8. The perforated dust collection grooves 21 are positioned directly opposite the outer horizontal housing 6. This facilitates cooperation with the scraper 8, allowing the dust scraped off by the scraper 8 to be discharged through the perforated dust collection grooves 21.

[0027] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The light-transmitting plate 2 is a cone shape that gradually slopes downwards from the outer edge to the center. This facilitates the automatic sliding of dust towards the hollow dust collection trough 21 under the action of gravity, and its discharge through the hollow dust collection trough 21.

[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer casing 6 is also equipped with a dust collection device 9 to facilitate the absorption of dust scraped off the light-transmitting plate 2.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The vacuuming device 9 includes a vacuuming housing 91 detachably connected to the bottom of the outer horizontal housing 6. The vacuuming housing 91 has an upward-facing vacuuming chamber 92. A transverse flow vacuuming impeller 93 is horizontally arranged within the vacuuming chamber 92. An air outlet 95, communicating with the air outlet end of the transverse flow vacuuming impeller 93, is located on the side of the vacuuming housing 91. The outer horizontal housing 6 has several vacuuming ports 61 penetrating the upper and lower ends of the outer horizontal housing 6 and capable of engaging with the opening of the vacuuming chamber 92. A filter element 94 is provided at the opening of the vacuuming chamber 92 to filter the passing airflow. When the transverse flow vacuuming impeller 93 rotates, it can draw in dust through the vacuuming ports 61. In conjunction with the self-cleaning device, it absorbs the dust scraped off during the self-cleaning device's operation. The filter element 94 is used to filter and collect dust for subsequent processing.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4The filter element 94 includes a filter screen 941 and a fixed frame 942 disposed around the filter screen 941. The fixed frame 942 is detachably connected to the opening of the suction chamber 92, facilitating the replacement of the filter element 94.

[0031] Working process of this invention:

[0032] This invention discloses an LED flat panel light with a self-cleaning function. During operation, the first drive motor 5 of the self-cleaning device drives the disc-shaped self-cleaning lampshade 3 to rotate. During rotation, the lampshade 3 cooperates with a brush mechanism to automatically wipe and clean the lower surface of the lampshade 3, improving its surface cleanliness. A scraper 8, in conjunction with the first drive motor 5, scrapes the upper surface of the light-transmitting plate 2 during its rotation, removing dust. This further improves the cleanliness of the upper surface of the light-transmitting plate 2. A dust collection device 9 absorbs the dust scraped off the light-transmitting plate 2.

[0033] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
