The following describes the illumination control process of the refrigeration and freezing apparatus 100 in the above-described embodiment with reference to the illumination control method of the refrigeration and freezing apparatus 100 in the present embodiment.
Fig. 4 is a schematic flow chart of an illumination control method of the refrigerating and freezing apparatus 100 according to an embodiment of the present invention. As shown in fig. 4, the lighting control method includes:
s402, detecting an event that the storage compartment 110 is opened;
s404, acquiring the illumination intensity of the storage room 110 detected by the light sensor 102 in real time in the process of opening the storage room 110;
s406, the illumination light source 101 is controlled to gradually turn on and then gradually turn off according to the illumination intensity.
As described above, the illumination light source 101 gradually lights up and then gradually becomes dark as the storage compartment 110 is opened, because the storage compartment 110 is opened in the front period of time, the storage compartment 110 is opened to a lesser extent, and the ambient light provides the storage compartment 110 with limited brightness, in this process, the controller 130 can control the illumination light source 101 to gradually light up, and as the storage compartment 110 is continuously opened, the opening degree becomes greater and greater, the ambient light can provide more brightness for the storage compartment 110, in this process, the controller 130 controls the illumination light source 101 to gradually become dark, so that when the storage compartment 110 is opened, the storage compartment 110 is illuminated by the ambient light and the illumination light source 101 at the same time, and the illumination requirement of the storage compartment 110 is met, and power consumption is saved.
The light intensity signal output by the light sensor 102 can be represented by an actual light intensity value, or an analog voltage signal corresponding to the light intensity, for example, 0 corresponds to no light, and 5V corresponds to the maximum light intensity.
The illumination light source 101 can be an LED light source, and can include a plurality of LED lamp beads that are evenly arranged, and the gradual change of illumination light source 101 is lighted or becomes dark gradually by controlling the lighting or extinguishing of part of the LED lamp beads.

When the illumination intensity is smaller than the preset illumination intensity, the opening degree of the storage room 110 is smaller, the ambient light entering the storage room 110 is limited, at the moment, the illumination light source 101 is gradually lightened, the storage room 110 is subjected to supplementary illumination, and meanwhile, the illumination requirement of the storage room 110 is met by means of the ambient light and the illumination light source 101.
In this process, the maximum brightness of the illumination light source 101 may reach the first preset brightness. And the speed of lighting that light source 101 was lighted gradually can increase along with the increase of illumination intensity, that is to say, along with opening gradually of storing room 110, ambient light gets into more and more, simultaneously, light source 101 also provides the illumination, the illumination intensity of storing room 110 can increase gradually, in the process of lighting source 101's gradual change is lighted, the speed of lighting of light source 101 and the increase of storing room 110 illumination intensity become positive correlation, in order to satisfy the illumination demand that the user probably carries out the access article operation to storing room 110 this moment.

Specifically, the step of controlling the illumination light source 101 in such a manner that it is gradually lit and then gradually dimmed according to the illumination intensity includes: when the illumination intensity is equal to or greater than the preset illumination intensity, the illumination light source 101 is controlled to gradually darken until the illumination light source darkens to the second preset brightness, and obviously the second preset brightness should be smaller than the first preset brightness. With the increase of the opening degree of the storage compartment 110, the storage compartment 110 is about to be completely opened, the storage compartment 110 can be illuminated by more ambient light, and the illumination requirement of the illumination light source 101 is gradually reduced, in the process, the illumination light source 101 can be gradually darkened to the second preset brightness, so that partial illumination of the storage compartment 110 by the illumination light source 101 can be guaranteed, and power consumption is saved.
The storage compartment 110 may be any refrigeration compartment of the refrigeration and freezing device 100, or may be a drawer-type storage space in the refrigeration compartment, if the storage compartment 110 is a drawer-type storage space, the refrigeration compartment has an accommodating space for accommodating a drawer, the drawer has an end plate, when the drawer is closed, the opening of the accommodating space is closed by the end plate to close the storage compartment 110, and the drawer is pulled out to open the storage compartment 110. Therefore, in the drawer type storage space, it is detected whether or not the drawer is drawn out by detecting that the storage compartment 110 is opened.
For a general storage compartment 110, the door 120 disposed at the access opening thereof may be used to open or close the storage compartment 110, and the event of detecting that the storage compartment 110 is opened includes detecting whether the door 120 is opened.
