The invention discloses a surface light source component and a refrigerator with the same. The surface light source component comprises a light source and a light guide plate vertically irradiated bythe light source, and the light source is arranged along the first side edge of the light guide plate; a plurality of light guide points are arranged on the front surface of the light guide plate, a through hole is vertically formed in the middle of the light guide plate, and the through hole comprises an upper edge close to the light source and a lower edge far away from the light source; a firstarea is formed in the position, close to the upper edge of the through hole, of the front surface of the light guide plate, the diameter of each light guide point in the first area is smaller than the diameter of each light guide point in the peripheral area of the first area, and the density of the light guide points in the first area is smaller than the density of light guide points in the peripheral area of the first area; a second area is arranged at the position, close to the lower edge of the through hole, of the front surface of the light guide plate, and the diameter of each light guide point in the second area is larger than that of each light guide point in the peripheral area of the second area, and the density of the light guide points in the second area is smaller than the density of light guide points in the peripheral area of the second area.
Description
technical field [0001] The invention belongs to the technical field of household appliances, in particular to a surface light source assembly and a refrigerator with the same. Background technique [0002] At present, the top lighting of the refrigeration compartment of the refrigerator can no longer meet the lighting needs, because the light can only illuminate part of the space. Shadow, inconvenient for users to find and take food. [0003] Therefore, there is now a surface light source assembly that can be installed on the back wall of the compartment. The light guide plate is arranged on the back wall of the compartment, and the light source is used to illuminate the light guide plate vertically, so that the entire light guide plate emits uniform and soft light, which can illuminate The whole room. However, for some ultra-wide refrigerators, it is necessary to open a through hole in the middle of the light guide plate, so that some devices can be fixed on the rear wall...
