  In FIG. 1, reference numeral 10 denotes a substrate, and reference numeral 14 denotes an LED light emitting element. A number of conductive circuits 11 are printed on the surface of the substrate 10, and the LED light emitting element 14 is soldered to an optimum place on the substrate 10. Thus, it can be mounted on the conduction branch circuit 11a, and the main circuit of the refrigerator 7 is energized through the inside of the electric wire 12 fixed to the terminal of the conduction circuit 11 by soldering 13.

  In FIG. 2, the interior lamp device is arranged on the back surface of the refrigerator compartment 8 of the refrigerator 7, and includes a confidential structure 16 a in which the front of the substrate 10 a on which the LED light emitting element 14 a is mounted is covered with a translucent cover. is doing. In addition, an interior lamp device comprising a confidential structure 16b in which the front side of the substrate 10b on which the LED light emitting element 14b is mounted is covered with a translucent cover is also provided on the side surface of the refrigerator compartment 8 of the refrigerator 7. The confidential structures 16a and 16b are housed in recesses formed on the inner wall surface.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the interior light device has the LED light emitting element 14 mounted directly on the substrate 10 and can prevent heat generation with low power, it can be mounted in the airtight structure 16 and the substrate 10 can be installed in the interior. By realizing the low-profile specification, the design can be improved without any bulge due to the mounting, and the compactness makes it possible to use any number of locations anywhere in the cabinet (in this case, just below each shelf position 9) ) Since the LED light-emitting element 14 can be installed, there are many foods 19 in the warehouse using the high directivity of the LED light-emitting element by directly setting the light irradiation direction 17 of the LED light-emitting element 14 to the central portion 18 in the warehouse Even if the shelves 9 are stored, the shelves 9 can reach the whole without blocking light, and the visibility of the food 19 in the warehouse can be improved.
