Abstract

An LED (light emitting diode) light bar assembly is comprised of an elongated casing having an elongated cavity of substantially U-shape cross-section. The casing has a base wall, opposed side walls and an elongated open end between the side walls. One or more elongated heat sink LED modules each having two or more LEDs and electrical component parts thereof are retained in each of the modules.
The LEDs are exposed in a spaced-apart relationship in a common wall of the modules. The casing is configured to removably receive and retain one or more of the modules therein in end-to-end relationship. The casing defines in combination with the one or more modules, at least one internal channel for the passage of wiring which is non-visible exteriorly of the module. At least one end connector is detachably securable to an end of the casing for securing the casing to a support structure. The connector has an internal passage for receiving wiring from the modules retained in the casing.

Claims (17)

1. An LED (light emitting diode) light bar assembly comprising an elongated casing having an elongated cavity of substantially U-shape cross-section defining a base wall, opposed side walls and an elongated open end between said side walls; one or more elongated heat sink LED modules each having two or more LEDs and electrical component parts thereof retained in each said module, said LEDs being exposed in a spaced-apart relationship in a common wall of said modules, said casing being configured to removably receive and retain one or more of said modules therein in end-to-end relationship, said casing defining in combination with said one or more modules at least one internal channel for the passage of wiring which is non-visible exteriorly of said module, and at least one end connector detachably securable to an end of said casing for securing said casing to a support structure and having an internal passage for receiving wiring from said modules retained in said casing.
2. An LED light bar assembly as claimed in claim 1 wherein said casing is a metal heat sink housing.
3. An LED light bar assembly as claimed in claim 2 wherein said opposed side walls are inwardly curved side walls, said modules having opposed parallel flat side walls, said common wall being a flat wall disposed adjacent said open end of said casing, there being two of said internal channels, one defined on opposed sides of said modules between said opposed parallel flat sidewalls and an inner face of said opposed side walls of said casing.
4. An LED light bar assembly as claimed in claim 3 wherein said base wall is a flat base wall, said module having a flat top wall opposed to said common wall and extending parallel thereto said flat top wall being retained in contact with said flat base wall for thermal conduction therewith.
5. An LED light bar assembly as claimed in claim 3 wherein said modules are each provided with cavities at opposed ends thereof and leading to said side walls thereof for the passage of electrical wires, said modules being retained in end-to-end facial contact in said casing cavity with said wires disposed in said internal channels.
6. An LED light bar assembly as claimed in claim 5 wherein said end connector has a hollow connecting hub dimensioned and configured for frictional sliding fit at a connecting end in a space adjacent a free end of said casing cavity, said wires being received and concealed in said hollow connecting hub which constitutes said internal passage, and connecting means for securing said connector to said support structure.
7. An LED light bar assembly as claimed in claim 6 wherein said connecting means is a transverse connecting flange at a free end of said hollow connecting hub, said flange having holes therein to receive fasteners.
8. An LED light bar assembly as claimed in claim 6 wherein said support structure is constituted by a vertical wall board, said flange being secured to an internal surface of said wall board with said hollow connecting hub extending through a mounting hole in said wall board and having said connecting end protruding beyond an outer surface of said wall board whereby to retain said free end of said casing adjacent said outer surface with said wires being non-visible.
9. An LED light bar assembly as claimed in claim 8 wherein said vertical wall board is part of an end wall of a display case, and a second exterior wall board secured to said internal surface of said wall board and having a channel therein for the passage of said wires, said flange being concealed between said wall boards.
10. An LED light bar assembly as claimed in claim 9 wherein said vertical wall board is removably secured adjacent said second exterior wall board.
11. An LED light bar assembly as claimed in claim 10 wherein said vertical wall board has a flat bottom wall, one or more support threaded bolts in said bottom wall for vertical wedging displacement and removal of said vertical wall board and said light bar assembly.
12. An LED light bar assembly as claimed in claim 11 wherein there is provided a further end connector at an opposed free end of said casing for support engagement against an opposed vertical wall of said display case.
13. An LED light bar assembly as claimed in claim 1 wherein said light bar is a miniature light bar having an overall transverse dimension of about 3/4 inch.
14. An LED light bar assembly as claimed in claim 1 wherein said elongated casing is an aluminum extruded casing.
15. An LED light bar assembly as claimed in claim 12 wherein said casing with said LED modules is rotatable between said end connectors to orient the direction of light emitted by said LED's.
16. An LED light bar assembly as claimed in claim 12 wherein a forced air supply is connected across said end connector to generate a cooling air current through said internal channels to cool said LED modules.
17. An LED light bar assembly as claimed in claim 1 wherein said LEDs are white light LED lamps.
