Abstract

A retrofit-style lamp is disclosed. The retrofit-style lamp includes a plurality of light sources, and a one-dimensional linear batwing lens. The one-dimensional linear batwing lens beam shapes light emitted by at least two light sources of the plurality of light sources. The retrofit-style lamp also includes a housing including the plurality of light sources, and attached to the one-dimensional linear batwing lens. The combination of housing and lens is then itself fitted with endcaps, including electrical connectors, for placement within a fixture, such as within an existing conventional fluorescent tube fixture located within a storage structure, for example a refrigeration case. Alternatively, the plurality of light sources, the one-dimensional linear batwing lens, and the housing may be formed, along with a power supply, as a standalone retrofit fixture for use in enclosed storage structures, such as refrigeration cases, where the retrofit fixture replaces a conventional fluorescent fixture.

Description

TECHNICAL FIELD

[0001] The present invention relates to lamps, and more specifically, to retrofit-style lamps incorporating a lens.BACKGROUND OF THE INVENTION

[0002] Enclosed storage structures, such as refrigeration cases, have long had light sources and light fixtures disposed within to provide light to anyone accessing an item or items stored within the structure. Typically, such a fixture uses one or more fluorescent bulbs, usually in the shape of a tube, to disperse light within the enclosed space defined by the storage structure. Such fixtures may be located along the front corners of a vertically-elongated storage structure, such as on either side of a door that opens to the left or right, or may be located along a top corner or a front edge, when the storage structure is horizontally-elongated. When a fluorescent tube breaks or otherwise ceases to function for any reason, the non-functioning tube is removed, and a new one is put into the fixture.

[0003] While fluorescent tubes are...
