LED LIGHTING ASSEMBLIES FOR DISPLAY CASES
First Claim
1. A method of retrofitting with light emitting diodes a display unit comprising at least one fluorescent bulb mounted on a mounting panel, a fluorescent driver, and at least one connecting wire connecting the fluorescent bulb and the fluorescent driver, the method comprising:
- a. removing the fluorescent bulb and mounting panel and the fluorescent driver from the display unit;
b. positioning a lighting assembly in the display unit, wherein the lighting assembly comprises;
(i) a frame; and
(ii) a plurality of light emitting diodes mounted on the frame;
c. positioning a light emitting diode driver in the display unit; and
d. electrically connecting the light emitting diode driver to the lighting assembly.

Abstract
Embodiments of lighting assemblies disclosed herein are particularly designed for installation in display units to more effectively distribute light towards, and thereby better illuminate, the products housed in the display unit. The lighting assemblies include at least one, but preferably a plurality of, light emitting diodes mounted on a frame. The frame is preferably formed so as to have a number of mounting arms on which to mount the LEDs. In this way, the LEDs can be positioned on the arms and their emitted light can be directed to focus on different aspects of the display unit (i.e., the products housed in the unit, banners or advertisements on the unit, etc.). The lighting assemblies may include, but do not have to include, various optical features to enhance the distribution of light emitted from the LEDs, including, but not limited to, lenses, reflectors, etc. The lighting assemblies disclosed herein may be retrofit into existing refrigerated display units illuminated by fluorescent bulbs or installed in new units during assembly.

10. A lighting assembly for a display unit comprising:
-
a. a frame comprising at least a first mounting arm and a second mounting arm oriented at an angle relative to the first mounting arm; b. at least one light emitting diode mounted on each of the first and second mounting arms, wherein the light emitting diodes mounted on the first and second mounting arms emit light and wherein at least some of the light emitted from the at least one light emitting diode mounted on the first mounting arm is directed in a first direction and at least some of the light emitted from the at least one light emitting diode mounted on the second mounting arm is directed in a second direction different from the first direction; and c. at least one lens positioned adjacent at least one light emitting diode, wherein the lighting assembly is insertable into and removable from the display unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A display unit having a top and a bottom and comprising:
-
a. a lighting assembly positioned proximate the top of the unit, wherein the lighting assembly comprises; (i) a frame comprising at least a first mounting arm and a second mounting arm oriented at an angle relative to the first mounting arm; (ii) at least one light emitting diode mounted on each of the first and second mounting arms, wherein the light emitting diodes mounted on the first and second mounting arms emit light and wherein at least some of the light emitted from the at least one light emitting diode mounted on the first mounting arm is directed in a first direction and at least some of the light emitted from the at least one light emitting diode mounted on the second mounting arm is directed in a second direction different from the first direction; and (iii) at least one lens positioned adjacent at least one light emitting diode; b. a light emitting diode driver positioned proximate the bottom of the unit; and c. a plurality of shelves each having a depth, wherein the depth of the shelves increases from the top to the bottom of the display unit.
