Preferably, the LED lamp is welded on the PCB circuit board, the PCB circuit board is placed on the air curtain of the L-shaped refrigerator using a buckle structure or screws, and the L-shaped lampshade is fixed on the air curtain of the L-shaped refrigerator using a buckle structure. On the curtain, the L-shaped refrigerating room air curtain is arranged on the inner wall of the refrigerating room, and the L-shaped refrigerating room air curtain is used to make the back lampshade and the top lampshade integrally form an L-shaped lampshade. the

According to the above structure of the present utility model, the lighting device is placed on the top and the back of the refrigerator compartment through the structural arrangement, and the LED lamp is used to make the refrigerator compartment light sufficient but not dazzling, and it looks elegant. , so that the energy consumption is reduced, which plays a role in saving energy. In addition, using the scattering effect of the L-shaped lampshade, the brightness of the refrigerator room is increased, but the glare of the light is avoided, the visual beauty is enhanced, and the use is guaranteed. the

Preferably, the utility model provides power supply to the LED lights via the top of the refrigerator by using the main control board arranged on the back of the refrigerator through the top position of the refrigerator, and light switches for controlling the LED lights are arranged on the inner walls of both sides of the refrigerator , the LED light is electrically connected to the refrigerator door switch through a slot on the PCB circuit board. the

The utility model is preferably, on the PCB circuit board, the LED element array that constitutes the backlight illuminant is provided with 54 LED lamps in series and parallel, and the LED element array that constitutes the top light illuminant is arranged in series and parallel. There are 24 LED lights. the

The utility model also relates to a refrigerator, in which the above-mentioned lighting device is installed on the air curtain from the top to the back of the refrigerator. the

According to the utility model, the lighting device is placed on the top and the rear of the refrigerating room to form an integrated structure, so that the light in the refrigerating room is bright but not dazzling, and there is no lighting dead angle in the refrigerating room; since the lighting device is installed on the top and the rear, it takes up The space is small, which increases the storage space of the refrigerator; because of the use of LED lights, it has energy-saving effect and increases the service life of the lighting device; because of the L-shaped structure, the interior of the refrigerator is beautiful and elegant. the

In addition, the utility model can also be applied to the refrigerating room of the freezer. the
