Abstract
A light bar and a refrigeration display using the light bar are disclosed. The light bar includes an optical component, a housing for reflecting light and a substrate assembly. The optical component and the housing together form a tube with a cavity. The substrate assembly is held in the cavity and includes a substrate and a plurality of LED light sources mounted on at least one side of the substrate. Light emitted from the plurality of LED light sources is irradiated to at least one predetermined area perpendicular to the substrate after passing through the optical component.
