Abstract

When the door of the refrigerator is opened, the white LED is operated by the main controller, and when the refrigerator door is closed, the white LED is turned off and the ultraviolet LED is operated to perform the freshness and deodorization function of the inside of the refrigerator. And the inside of the refrigerator can be sterilized by irradiating the inside of the refrigerator with ultraviolet rays. In addition, since the ultraviolet lamp is replaced with the conventional ultraviolet lamp, the device can operate at a low voltage of 3V, It is equipped with white LED and ultraviolet LED on one PCB board to reduce the installation area, which is advantageous for securing the space of the refrigerator, and it is excellent in cost competitiveness because the inverter circuit to be incorporated into the conventional lamp is not included.

Description

[0001] LED module refrigerator lights and sterilization [

The present invention relates to an LED module capable of lighting and sterilizing a refrigerator. More particularly, when the refrigerator door is opened, a general LED is turned on and the ultraviolet LED is turned on when the door of the refrigerator is closed so that freshness and deodorization functions of the inside of the refrigerator can be performed. It is.

In general, a refrigerator is provided with a storage room such as a freezer compartment or a refrigerating compartment, and the interior or exterior of the refrigerator installed on the upper or rear surface of the storage compartment is lit or turned off by opening and closing a door switch installed at one side of the refrigerator, It has been possible to distinguish foods stored therein.

In such a conventional refrigerator, the inside or outside of the refrigerator generally uses a large amount of heat, such as an incandescent lamp, to cause a heat loss inside the refrigerator due to the heat generated by the inside of the refrigerator. So that it can only function as a light source of the light source.

In order to solve the above-described problems, the present invention provides a refrigerator which is capable of operating the white LED in the main controller when the refrigerator door is opened, turning off the white LED when the refrigerator door is closed, and operating the ultraviolet LED will be.

The present invention can prevent an increase in the temperature of the inside of the refrigerator due to the heat generated from the inside or the outside of the refrigerator. The inside of the refrigerator can be sterilized by irradiating ultraviolet rays into the inside of the refrigerator. It is economical to operate with a low voltage of 3V by using a white LED and an ultraviolet LED on a single PCB substrate to reduce the installation area and thus it is advantageous in securing a refrigerator space, The price competitiveness is excellent.

1 is a block diagram of an internal control system according to the present invention;
Fig. 2 is a view showing a PCB substrate of the present invention according to the present invention; Fig.

In the interior of the refrigerator, which is installed inside the refrigerator and is turned on and off according to the opening and closing of the refrigerator door,

And a PCB substrate 2 connected to the main controller 1 and having a white LED 3 and an ultraviolet LED 4 fixed thereto.

The present invention will now be described in detail with reference to the accompanying drawings.

A white LED 3 and a UV LED 4, which are light sources for emitting light, are provided on a PCB substrate 2 connected to a main controller 1 installed in a machine room provided with a number of components for cooling the refrigerator In the case where the door of the refrigerator is opened, the white LED 3 is illuminated by the circuit provided in the main controller 1 to illuminate the inside of the refrigerator, When the door is closed, the white LED 3 is turned off and the ultraviolet LED 4 is turned on to perform freshness and deodorization functions of food and beverages inside the refrigerator.
