Description

A refrigerator sterilization LED lamp

technical field

The utility model belongs to the technical field of semiconductor lighting, in particular to a refrigerator sterilizing LED lamp.

Background technique

With the development of modern technology and the improvement of people's living standards, refrigerators have become an indispensable part of people's lives. At present, refrigerators on the market generally use low temperature to inhibit the growth of bacteria, so as to achieve the purpose of preserving food for a long time. However, this method does not kill the bacteria, and the food will still deteriorate due to the growth of bacteria within a period of time.

There are many technologies that can be used to eliminate bacteria in the air, such as chemical sterilization, ozone sterilization, traditional low-pressure mercury lamp ultraviolet light sterilization, etc. Chemical sterilization technology uses chemical reagents to sterilize, chemical reagents are easy to remain on the surface of objects, and the harmful substances produced are not easy to degrade, which brings potential harm to human body and environment; ozone sterilization technology uses high voltage to stimulate air discharge to generate ozone , Ozone destroys the structure of the microbial membrane by the oxidation of oxygen atoms to achieve bactericidal effect; the principle of ultraviolet sterilization is that the energy of ultraviolet photons is absorbed by the base pairs in DNA, causing genetic material to mutate, causing the bacteria to die immediately or cannot reproduce. So as to achieve the purpose of sterilization. The first two methods are obviously not suitable for the refrigerator environment, while the ultraviolet sterilization technology can be used to sterilize the space in the refrigerator. The commonly used ultraviolet light source is a low-pressure mercury lamp, which uses a low-pressure mercury vapor discharge to generate ultraviolet radiation. However, the use of low-pressure mercury lamps in the refrigerator has some disadvantages: first, the discharge substance mercury of the low-pressure mercury lamp is a heavy metal, which is very harmful to the human body if it is damaged and leaks, and it is not conducive to repair and maintenance after the glass lamp tube is damaged; the second is the switch Refrigerator doors cause low-pressure mercury lamps to start frequently, shortening their lifespan.

Patent CN200920238236.3 discloses a refrigerator with a magnetic field light wave sterilization and preservation device. On the top or side of the refrigerator liner, the magnetic field light wave sterilization and preservation device is fixed by screws or clips. Although it has an excellent bactericidal effect, it uses ozone to sterilize, and the residual ozone is relatively harmful to the human body.

Utility model content

The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art, and provide a refrigerator sterilizing LED lamp, which adopts ultraviolet sterilization technology to kill bacteria, has remarkable effect, can effectively inhibit food spoilage, and is safe No pollution.

The technical solution adopted by the utility model to solve the above problems is:

A refrigerator sterilizing LED lamp, comprising a substrate, a UVC-LED packaging device is installed on the front of the substrate, a driver for driving the UVC-LED packaging device and a controller for controlling the operation of the driver are installed on the back of the substrate, the UVC-LED packaging The peak wavelength of light emitted by the device is 200-285 nm.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the utility model and the utility model is not limited to the following examples.

A refrigerator sterilization LED lamp as shown in Figures 1 to 2 includes a substrate 1, a UVC-LED packaging device 9 is installed on the front of the substrate 1, and a driver 3 for driving the UVC-LED packaging device 9 is installed on the back of the substrate 1. The controller 5 that controls the work of the driver 3, the peak wavelength of the light emitted by the UVC-LED packaging device 9 is 268 nm. This sterilizing LED lamp adopts ultraviolet sterilizing technology to kill bacteria, the effect is remarkable, it can effectively inhibit food spoilage, and it is safe and pollution-free. After repeated tests, the ultraviolet light with a wavelength of 268nm can achieve the maximum bactericidal effect.

The controller 5 is provided with a timing device (not shown in the figure), and the controller 5 controls the opening time of the UVC-LED packaging device 9 through the timing device. When the refrigerator door is opened, the controller 5 controls the driver 3 to disconnect the power supply of the UVC-LED packaging device 9, thereby protecting the user from ultraviolet rays. When the refrigerator door is closed, the controller 5 controls the driver 3 to drive the UVC-LED packaging device 9 for half an hour through the timing device, and then cuts off the power supply of the UVC-LED packaging device 9 . The opening time of the UVC-LED packaging device 9 is controlled by the timing device, so that while effectively killing bacteria and preventing food spoilage, energy waste is greatly reduced.
