Abstract

A lighting assembly including an elongated mounting component with two elongated and angled mounting surfaces, two or more LED-based printed circuit board having a plurality of LEDs on one surface and circuitry on a second surface. The printed circuit boards are fastened to the mounting surfaces, by a plurality of longitudinally-spaced nonconductive fasteners, substantially parallel but elevated above the mounting surfaces. The lighting assembly is configured to be mountable to extend within existing light fixtures such that the LEDs are positioned to provide a light pattern similar to the illumination pattern previously produced by the original fixture.

Claims

1. A lighting assembly for installation in an existing light fixture, the lighting assembly comprising:

an elongated mounting component with two elongated mounting surfaces;

two or more elongated printed circuit boards including a plurality of LEDs on a first surface and circuitry on a second surface, the printed circuit boards fastened to the mounting surfaces using longitudinally-spaced nonconductive fasteners, substantially parallel to but elevated above the mounting surfaces thus creating a vertical gap between the mounting surfaces of the mounting component and the relatively parallel printed circuit boards;

wherein the lighting assembly is configured to be mountable to extend within the existing light fixture such that the LEDs are positioned to direct light outwardly and downwardly from a longitudinal axis of the existing lighting fixture to form light output which is a substitute for a lighting pattern previously exhibited by the existing light fixture.

2. The lighting assembly of claim 1, wherein each of the two or more elongated printed circuit include at least two smaller printed circuit boards and a connector device physically and electrically connecting adjoining ends of each of the smaller printed circuit boards.

3. The lighting assembly of claim 1, wherein when the lighting assembly is mounted to the existing light fixture, the mounting surfaces are positioned at outward angles having ranges of 10 degrees to 20 degrees from a horizontal plane defined by the existing lighting fixture.

4. The lighting assembly of claim 1, wherein, when the lighting assembly is mounted to the existing light fixture, the mounting surfaces are positioned at outward angles having ranges of 12.5 degrees to 17.5 degrees from a horizontal plane defined by the existing lighting fixture.

5. The lighting assembly of claim 1, wherein, when the lighting assembly is mounted to the existing light fixture, the mounting surfaces are positioned at outward angles having ranges from about 13.5 degrees to 16.5 degrees from a horizontal plane defined by the existing lighting fixture.

6. The lighting assembly of claim 1, wherein, when the lighting assembly is mounted to the existing light fixture, the mounting surfaces are positioned at outward angles approximately 15 degrees from a horizontal plane defined by the existing lighting fixture.

7. The lighting assembly of claim 1, the elongated mounting component includes a power support portion with at least one component that provide power to the lighting assembly, wherein the at least one component is positioned between the mounting component and the existing lighting fixture when the lighting assembly is mounted to the existing light fixture.

8. The lighting assembly of claim 1, wherein a circuitry arrangement on the two or more printed circuit boards includes components configured to illuminate the LEDs contained by the two or more printed circuit boards in a dimming pattern.

9. The lighting assembly of claim 1, wherein a circuitry arrangement of the two or more printed circuit boards includes components configured to illuminate the LEDs contained by the two or more printed circuit boards in a bi-level dimming pattern.

10. The lighting assembly of claim 1, wherein a circuitry arrangement of the two or more printed circuit boards includes components configured to switch between a grid-based power source and an alternative battery-based power source located in the lighting assembly based on receipt of a signal transmitted by a local communications device.

11. A light assembly comprising:

an elongated mounting component with two elongated mounting surfaces;

two or more elongated printed circuit boards including a plurality of LEDs on a first surface and circuitry on a second surface, the printed circuit boards fastened to the mounting surfaces using longitudinally-spaced nonconductive fasteners, substantially parallel to but elevated above the mounting surfaces thus creating a vertical gap between the mounting surfaces of the mounting component and the relatively parallel printed circuit boards;

wherein the lighting assembly is configured to be mountable to extend within the existing light fixture such that the plurality of LEDs are positioned to direct light outwardly and downwardly from a longitudinal axis of the existing lighting fixture to form light output which is a substitute for a lighting pattern previously exhibited by the existing light fixture

a main AC power supply;

a DC power supply included along with a chargeable battery;

a networked processing component included in the assembly, the networked processing component adapted to transmit a signal based on a received condition, the signal causing the plurality of LEDs to be powered by the DC power supply thus draining the battery.
