Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1 and 2, the present invention provides an LED device for sterilization of a refrigerator, which includes an LED lamp 10 and a controller 20. The LED lamp 10 includes a plurality of LED lamps 11 and sensors 12 arranged side by side slidably connected to the top of the inside of the refrigerator 30 in a vertical direction. The LED lamp 11 is a blue LED of a point light source, and is used to vertically irradiate the surface of the storage to sterilize and keep fresh. The sensor 12 is used for acquiring real-time vertical distance information between the LED lamp 11 arranged in parallel and the top end of the storage object and sending the information to the controller 20. The controller 20 is located inside the refrigerator 30, and the controller 20 is communicatively connected to the LED lamp 11 and the sensor 12, respectively. The controller 20 sends out first driving information for driving the LED lamp 11 to approach or depart from the stored object in the vertical direction according to the received real-time vertical distance information.
In the above embodiment, the controller 20 sends the first driving information according to the real-time vertical distance information between the LED lamp 11 and the top end of the storage object sent by the sensor 12, so as to drive the LED lamp 11 to slide along the vertical direction, so as to automatically and rapidly adjust the irradiation distance between the LED lamp 11 and the storage object corresponding to the lower part of the LED lamp, thereby realizing the intelligent adjustment of the vertical irradiation distance between the storage object surfaces with different sizes and different heights and the plurality of LED lamps 11 corresponding to the upper part of the storage object, and achieving the effects of uniform irradiation, sterilization and fresh-keeping.
As a preferred embodiment, the controller 20 is further configured to send out second driving information for simultaneously controlling the on/off of the sensor 12 and the LED lamp 11. The second driving information controls the simultaneous on and off of the sensor 12 and the LED lamp 11, and the controller 20 can rapidly send the first driving information according to the real-time vertical distance information sent by the sensor 12 to drive the LED lamp 11 to vertically slide so as to quickly read and adjust the distance between the LED lamp 11 and the surface of the storage object.
Preferably, the LED lamp 10 further includes a plurality of telescopic rods 13 having top ends connected to the top and bottom ends of the inside of the refrigerator 30, and the LED lamp 11 and the sensor 12 are respectively arranged in parallel. The telescopic link 13 is electrically connected with the controller 20, and the first drive information drive telescopic link 13 that the controller 20 sent is flexible along vertical direction, and telescopic link 13 is along vertical direction concertina movement, drives the LED lamp 11 that its bottom set up side by side and is close to or keeps away from the storage that the below corresponds, and then adjusts the perpendicular irradiation distance on LED lamp 11 and the storage surface that its below corresponds. As a further preference, the top end of the telescopic rod 13 is rotatably connected to the top of the inner side of the refrigerator 30; the controller 20 sends out third driving information for driving the top end of the telescopic rod 13 to rotate around the top of the inner side of the refrigerator 30 according to the real-time vertical distance information.
