LED lighting device for refrigerated food merchandising display cases
First Claim
1. An LED (light emitting diode) lighting device for connection into end connectors of a conventional fluorescent lighting fixture for replacement of fluorescent tubes, said fluorescent lighting fixture being secured in a refrigerated merchandising display case for displaying foodstuff, said elongated rigid support body being mounted to orient a directional light beam produced by said LEDs onto the foodstuff, said device comprising an elongated rigid aluminum support body having pin connectors at opposed ends thereof, said support body constituting an external heat sink to dissipate heat generated by said power conversion circuit and said LEDs, said pin connectors are each provided with a pair of electrical connecting pins extending exteriorly thereof in a spaced-apart configuration for operatively engaging said end connectors, circuit board means is secured along said rigid support body, a plurality of LEDs are secured together and to said circuit board means in a linear arrangement to form said directional light beam, power conversion circuit means secured to said pin connectors for supplying voltage to said LEDs connected together.

Abstract
A multiple LED lighting device and appropriate electrical components integrated into two versions and serving as a direct replacement for conventional fluorescent lighting used in refrigerated food merchandisers. Both versions include appropriate connectors and pins, enabling the LED lighting device to be installed directly in a food merchandising display case lighting fixture. The LED lighting supply circuit may include appropriate electrical components such as rectifiers, step-down transformers, regulators and colour rendering controls to provide the required voltage for the LEDs and appropriate light spectrum. The electrical components may be mounted either integrally within the device, incorporated in an end cap thereof, or installed separately within the refrigerated food merchandising display case. The light may be coloured within the permissible light spectrum by the use of appropriate LEDs and drivers providing the desired coloured lighting.
