The present invention relates to a refrigerator and lighting inside the refrigerator.

In general, a refrigerator is a home appliance that allows food to be stored at a low temperature in an interior storage space shielded by a door, and is stored by cooling the inside of the storage space using cold air generated through heat exchange with a refrigerant circulating in a refrigeration cycle. It is configured to keep foods in optimal condition.

Such refrigerators are becoming larger and more versatile as the dietary changes and user's preferences are diversified. Various storage means such as drawers, shelves, and baskets are provided in the storage space.

The inside of the refrigerator is provided with lighting for illuminating the inside of the refrigerator when the refrigerator door is opened. Such a light bulb is used as a general bulb type lamp, but if there is food inside, it is impossible to illuminate the inside evenly, and the volume of the bulb itself is also small, resulting in a loss of storage capacity in the room. In addition, there was a problem that the internal temperature rises due to the heat generation of the light bulb itself, and there is a problem that must be frequently replaced with a relatively short lifespan.

In order to solve such a problem, the lighting apparatus which uses LED as a light source in the inside of a refrigerator is developed. However, in the case of a lighting device using the LED, since the parts price of the LED is expensive, there is a problem that the manufacturing cost increases when using a plurality of LEDs to reveal the interior. If you use less LED, there is a problem that can not fully reveal the height.

In addition, the refrigerator according to an embodiment of the present invention, the body to form a storage space; An LED provided on an inner wall of the main body and emitting light in a direction crossing the inner side of the storage space; It is mounted on the inner wall of the main body corresponding to the side of the LED, and a plurality of grooves for guiding the light irradiated from the LED is formed in the width direction includes a lamp cover to be able to irradiate light forward along the groove It is configured by.

According to the refrigerator and the interior lighting apparatus according to the embodiment of the present invention having the above configuration, the light emitted to the side by the LED is guided along the groove of the lamp cover is emitted forward. In addition, a plurality of such grooves are regularly arranged in the vertical direction of the lamp cover.

Accordingly, the light is evenly emitted from the entire lamp cover, thereby making it possible to brighten the entire interior of the lamp evenly. As a result, a smaller number of LEDs can be used and the interior height can be effectively revealed, thereby reducing the manufacturing cost.

In particular, by arranging LEDs on only one side of both sides of the lamp cover, and by emitting light forward from both ends of the lamp cover through the entrance portion and the exit portion it is possible to further reduce the manufacturing cost.

In addition, the light is irradiated along the groove into the storage space inside the lamp, so that the lamp cover has a certain pattern, thereby making the interior more luxurious overall.
