Problems solved by technology

The sterilizing effect of LED lights is related to its irradiation distance, but the storage items in the refrigerator are of different sizes and uneven heights, which makes the irradiation distance from the protruding dome-shaped LED lights to the surface of each storage item different, thus making sterilization and freshness preservation uneven effect

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] Such as figure 1 and figure 2 As shown, 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 several LED lamps 11 and sensors 12 arranged side by side and slidably connected to the inner top of the refrigerator 30 along the vertical direction. The LED lamp 11 is a blue light LED of a point light source, and is used for vertically illuminating the surface of the storage to sterilize and keep fresh. The sensor 12 is used to collect the real-time vertical distance infor...

Abstract

A light-emitting diode (LED) device for use in the sterilization of a refrigerator, comprising: an LED lamp (10), comprising a plurality of LED lamps (11) and sensors (12), which are arranged side-by-side and which are slidably connected in the vertical direction to a top portion of an inner side of a refrigerator (30); a controller (20), which is located at the inner side of the refrigerator (30), the controller (20) being communicably connected to the LED lamps (11) and the sensors (12), respectively; the LED lamps (11) are blue LEDs which vertically illuminate a surface of a stored object (31), while the sensors (12) are used to acquire information on the real-time vertical distance between an LED lamp (11) that is arranged therebeside and a top end of the stored object (31), sending said information to the controller (20); according to the received real-time vertical distance information, the controller (20) sends first driving information to drive an LED lamp (11) to move in the vertical direction toward or away from the stored object (31). The LED device allows the vertical illumination distance between the LED lamp (11) and the stored object (31) in the refrigerator to be adjusted automatically, thus attaining the effects of uniform illumination, sterilization and fresh-keeping.

Description

technical field [0001] The invention relates to the technical field of refrigerator sterilization, and more specifically, the invention relates to an LED device for refrigerator sterilization. Background technique [0002] The device installed inside the refrigerator and sterilizes by lighting includes ultraviolet lamps and LED lamps. Ultraviolet lamps have been gradually eliminated because they are harmful to human eyes. Low-temperature storage of blue LED lamps can achieve antibacterial and fresh-keeping effects, and are increasingly used in refrigerator sterilization, fresh-keeping and lighting. [0003] In the prior art, most of the LED lights installed inside the refrigerator are protruding dome-shaped lights, which irradiate the stored items below to realize sterilization, preservation and illumination. The sterilizing effect of LED lights is related to its irradiation distance, but the storage items in the refrigerator are of different sizes and uneven heights, which...
