A refrigerator includes a main body having a storage room formed therein, a door that opens and closes the storage room, a filter module, and a cool air circulation fan that circulates cool air through the filter module. The filter module includes a metal photocatalyst filter and a UV LED module for radiating UV rays to the metal photocatalyst filter. The metal photocatalyst filter has photocatalysts made of one of ZnTiO.sub.2, CuTiO.sub.2, AgTiO.sub.2 or FeTiO.sub.2 coated on a filter base. The filter module may allow the entire storage room to be uniformly subject to antibiosis and sterilization at a relatively low cost.

A door for a refrigeration unit having a transparent panel assembly having an outer transparent panel and an inner transparent panel. The outer transparent panel has an outer side, an inner side, and top, bottom, left, and right edges and the inner transparent panel has an outer side, an inner side and top, bottom, left, and right edges. A decorative design is applied to the inner side of the outer transparent panel. A population of light sources are positioned on the top, bottom, left and/or right edges of the outer transparent panel and are capable of emitting light into the outer transparent panel, such that the decorative design is capable of being illuminated by the population of light sources.

A cooling unit has an internal chamber having a linear lighting source (an in-line lighting source) that has a row of light sources. The row of light sources are has at least one visible light section and at least one ultraviolet light section. The visible light sections and the ultraviolet light sections are all aligned in a single line and the visible light section and the ultraviolet light section are alternatingly placed in the line so a visible light section is adjacent to a ultraviolet light section. The visible light section has one or more visible light emitting LEDs and the ultraviolet light section has one or more ultraviolet light emitting LEDs. Each of the visible light emitting LEDs and the ultraviolet light emitting LEDs are all aligned in the line, as well as the visible light sections and the ultraviolet light sections.
