[0026] Reference Figure 1-8 The present invention provides a technical solution: a multi-combination LED flat panel light suitable for different scenes, which includes an outer ring frame 6 and an LED light strip 10, wherein the outer ring frame 6 is provided with a reflective plate 1, a light guide plate 2 and a frosted plate 3 from bottom to top, and the LED light strip 10 is arranged at the front and rear side edges of the light guide plate 2, and a ring layer frame 4 is provided between the light guide plate 2 and the frosted plate 3, wherein a layer cavity 41 is formed in the ring layer frame 4, and a plurality of flow ports 42 are respectively opened on the front and rear frame surfaces of the ring layer frame 4, and a cross rotating plate 43 is rotatably installed in the flow port 42, and a guide tube 8 for guiding the gas in the left and right frame groove cavities of the outer ring frame 6 is provided, and a flow driving fan 81 is provided in the guide tube 8, and a drainage mechanism 9 for regulating the drainage of the gas in the front and rear frame groove cavities of the outer ring frame 6 is provided in the front and rear frame groove cavities.

[0027] In this embodiment, a sealing ring gasket 61 is further included for sealing the upper end surface of the grinding plate 3 and the outer ring frame 6 .

[0028] In this embodiment, it includes connecting corner seats 91 arranged at the four end corners of the frame groove cavity of the outer ring frame 6, and the drainage mechanism 9 includes: a sliding rod 92, both ends of which are fixed on the connecting corner seats 91 on the left and right sides, and two groups are arranged in parallel; a sliding shell 93, which is slidably connected on the sliding rod 92, and a choke fan 94 is rotatably installed in the inner shell center, and a push plate 95 is fixed to the corner end of the outer shell wall near the LED light strip 10; and the sliding shell 93 in the drainage mechanism 9 arranged in the front and rear frame grooves is a centrally symmetrical structure; wherein the choke fan is a non-powered drive rotation mode, while the flow-displacing fan adopts a power-driven drive rotation mode, therefore, through the active flow-displacing gas flow of the flow-displacing fan, the choke fan can be driven to rotate and the sliding shell can be driven to slide along the direction of the sliding rod, and in addition, the power drive mode of the flow-displacing fan is also set to a forward and reverse drive mode to promote the reciprocating sliding movement of the sliding shell;

[0029] In this embodiment, a rotator 96 is installed in the communication cavity of the communication angle seat 91 on the right front side, and a swing plate 97 for closing / opening the communication cavity of the communication angle seat 91 is installed on the rotator 96.

[0030] In this embodiment, the cavity of the guide tube 8 located before and after the flow-displacing fan 81 is filled with moisture-absorbing cotton mesh columns 82 .

[0031] In this embodiment, an axial column opening channel is opened in the moisture-absorbing cotton mesh column 82 .

[0032] In this embodiment, a ring layer frame 2 5 is provided below the reflector 1, a layer cavity 2 51 is formed in the ring layer frame 2 5, and a sealing plate 62 for sealing the layer cavity 2 51 is provided below the ring layer frame 2 5, and a plurality of flow ports 2 52 are respectively opened on the front and rear frame surfaces of the ring layer frame 2 5, a cross-turn plate 2 53 is rotatably installed in the flow port 2 52, and the flow port 2 52 is staggered with the flow port 1 42. That is to say, during the sliding process of the sliding sleeve shell, the cross-turn plate 1 and the cross-turn plate 2 are alternately pushed in turn, and the rotation installation of the cross-turn plate 1 and the cross-turn plate 2 are assembled with a micro-damping force damping shaft. It needs to be explained that when the sliding sleeve shell completes each sliding push, When the cross-turn plate 1 / the cross-turn plate 2 is formed, in the process of pushing the cross-turn plate 1 / the cross-turn plate 2 to rotate, the corresponding flow port 1 / flow port 2 is opened, and after completing pushing the cross-turn plate 1 / the cross-turn plate 2 to rotate, the corresponding flow port 1 / flow port 2 is closed, so that the gas entering the annular layer frame 1 and the annular layer frame 2 of the thinner thickness layer structure is evenly and comprehensively exchanged, thereby allowing the heat generated by the light guide plate and the LED light strip to dissipate in time, and the gas passing through the hygroscopic cotton mesh column is subjected to moisture absorption treatment, thereby preventing moisture in the external environment from invading the flat panel lamp and corroding the flat panel lamp, thereby ensuring the dryness inside the flat panel lamp.

[0033] As a preferred embodiment, a humidity sensor is included for monitoring the humidity of the gas.

[0034] In this embodiment, a heat dissipation rod 83 extending into the tube cavity of the guide tube 8 is provided in the annular layer frame 5. The heat dissipation rod 83 is covered with a heat dissipation fin 84 with one end located in the layer cavity 2 51 and the other end located outside the sealing plate 62. The heat dissipation fin located in the layer cavity 2 is also beneficial to the diversion effect of the gas in the layer cavity 2, thereby improving the heat exchange efficiency.

[0035] In specific implementation, when the LED flat panel light is in use, the swing plate is in a closed connecting cavity state, and the flow-driving fan on one side is in a stopped state. The flow-driving fan on the other side is started to drive the sliding shell to move back and forth, so that the gas in the annular frame 2 and the annular frame 1 can be exchanged and heat-exchanged in real time, thereby dissipating heat for the flat panel light. When the humidity sensor detects that the flowing gas still has a certain humidity, at this time, it will feedback to close the forward and reverse driving mode of the flow-driving fan, and the rotator will control the swing plate to open the connecting cavity. The stopped flow-driving fan is also started, so that the gas circulates in the outer ring frame groove cavity for dehumidification until the humidity sensor monitoring returns to zero, and the forward and reverse driving mode of the flow-driving fan is restored again, and the flow-driving fan on the corresponding side is stopped. A humidity sensor alarm for monitoring its humidity value is set in the hygroscopic cotton mesh column, so as to timely remind the replacement of the hygroscopic cotton mesh column, thereby ensuring that the LED flat panel light can be used for normal operation in different scene environments.

[0036] The above description is only a preferred specific embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
