Refrigerator

Abstract

A refrigerator includes: a main body cabinet forming a storing compartment which has a front opening formed with a predetermined height and width; and a plurality of illumination units disposed along an inner circumference of the main body cabinet and adjacent to the front opening; each illumination unit comprising a light source which has a predetermined light directivity angle θ, and each light source of the plurality of illumination units is disposed not to be superposed with each other.

1 . A refrigerator comprising:
 a main body cabinet forming a storing compartment which has a front opening formed with a predetermined height and width; and   a plurality of illumination units disposed along an inner circumference of the main body cabinet,   each illumination unit comprising a light source which has a predetermined light directivity angle θ, and   the light directivity angle θ of each of the light sources is disposed to not be superposed with the light sources on the opposite side of the inner circumference, and the light sources are disposed to emit light toward an inside of the storing compartment.   
   
   
       2 . The refrigerator according to  claim 1 , wherein the plurality of illumination units are adjacent to the front opening. 
   
   
       3 . The refrigerator according to  claim 2 , wherein if the width of the front opening is W then a height interval H 1  of the plurality of illumination units satisfies the following equation:
     H 1≦ W× tan(θ/2).   
   
   
       4 . The refrigerator according to  claim 2 , wherein if a height of the front opening is H, then a width interval W 1  of the plurality of illumination units satisfies the following equation:
     W 1 ≦H ×tan(θ/2).   
   
   
       5 . The refrigerator according to  claim 3 , wherein if a height of the front opening is H then a width interval W 1  of the plurality of illumination units satisfies the following equation:
     W 1 ≦H ×tan(θ/2).   
   
   
       6 . The refrigerator according to  claim 1 , wherein the light directivity angle θ of the light sources is 120 to 160 degrees. 
   
   
       7 . The refrigerator according to  claim 5 , wherein the light sources comprise a light-emitting diode (LED). 
   
   
       8 . The refrigerator according to  claim 2 , further comprising an inner wall of the main body cabinet, wherein the illumination units further comprise a housing which has an opening that the respective light source passes through and is received in the inner wall of the main body cabinet, and a cover which is made of a transparent material and covers the opening of the respective housing. 
   
   
       9 . The refrigerator according to  claim 8 , wherein the covers guide light irradiated by the respective light sources to diverge inside the storing compartment. 
   
   
       10 . A refrigerator comprising:
 a main body cabinet forming a storing compartment which has a front opening formed with a predetermined height and width; and   a plurality of illumination units disposed along an inner circumference of the main body cabinet,   the plurality of illumination units being disposed in a zigzag arrangement along the inner circumference of the main body cabinet.   
   
   
       11 . The refrigerator according to  claim 10 , wherein the illumination units each comprise a light source which has a predetermined light directivity angle θ. 
   
   
       12 . The refrigerator according to  claim 11 , further comprising an inner wall of the main body cabinet, wherein the illumination units further comprise a housing which has an opening that the respective light source passes through and is received in the inner wall of the main body cabinet, and a cover which is made of a transparent material and covers the opening of the respective housing.
