Description

Refrigerator {Refrigerator}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus for a refrigerator, and more particularly, to a lighting apparatus for a refrigerator capable of increasing the amount of light irradiated on a storage stored in a storage space of the refrigerator with a relatively low manufacturing cost.

2. Description of the Related Art Generally, a refrigerator is designed for low-temperature storage of food, and is configured to cool a storage space inside a refrigerator by circulation of a plurality of electric components and a working fluid constituting a refrigeration cycle.

Such a refrigerator has a variety of configurations as well as a large size and a multifunctional due to changes in the living environment. Various refrigerators including a kimchi refrigerator have been developed in accordance with the trend.

In recent years, a technique has been developed and applied to enhance the freshness of a product by irradiating various colors of light to a storage material stored in the storage space. In order to irradiate light of various colors into the storage space as described above, A light emitting diode called a LED (Lighting Emitting Diode) is widely used.

However, the light emitting diode used in the conventional refrigerator lighting has the following problems.

In order to maintain the freshness of the stored product stored in the refrigerator, the amount of light emitted from the lighting device must exceed a certain level. However, since the quantity of light irradiated from one LED is relatively small, a large number of LEDs are required to obtain a sufficient quantity of light.

However, since the price of the light emitting diode is relatively high, there is a problem that the additional cost becomes very large in order to obtain the light quantity required for the stored product.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lighting apparatus for a refrigerator capable of increasing the amount of light irradiated on a storage object stored in a storage space of a refrigerator with a relatively small manufacturing cost, .

The lamp is provided such that light is radiated in both lateral directions of the door.

 The lamp may be a light emitting diode (LED).

Wherein the reflective member is formed of an aluminum plate so that light emitted from the lamp is directed to the storage space.

According to another aspect of the present invention, there is provided a lighting apparatus for a refrigerator, comprising: storage sensing means for sensing whether a storage object is received in the storage compartment, the compartment being mounted at a plurality of inner sides of the storage compartment; The plurality of mounted lamps are respectively connected to the storage sensing means, and only the lamp for sensing the storage accommodation is illuminated.

According to the lighting device of the refrigerator according to one aspect of the present invention,

Most of the light irradiated from the lamp is irradiated to the stored product stored in the refrigerator by the reflecting member. Therefore, there is an advantage that a sufficient amount of light for maintaining the freshness can be obtained even with a relatively small number of lamps.
