Abstract

The invention is a low voltage ceiling or wall mounted light fixture for residential and commercial lighting, having included a plurality of high lumen white LED lights incorporated within the fixtures, a light color diffusion panel and a household current to low voltage DC converter within the fixture to convert the AC current to low voltage DC current, saving on the cost of power required to provide illumination for the resident or commercial application and virtually eliminating the need to replace incandescent or fluorescent bulbs, the LED lights having an average duration of over 150,000 hours.

Claims

1. An interior light fixture using bright white LEDs for an illumination source, powered by low voltage DC current, the device comprising:

a multiple terminal low voltage power supply wired into a standard household or commercial electrical system, the multiple terminal low voltage power supply including a transformer converting 110 and 220 volt AC current to low voltage DC current;

one or more low voltage DC current bright white LED light fixtures containing one or more bright white LED light sources, comprised from a plurality of bright white LED lamps;

a DC light switch;

a DC dimmer switch; and

an auxiliary power terminal which may be attached to an alternate DC power supply in the event of an AC power outage.

2. The device, as disclosed in claim 1, wherein the multiple terminal low voltage power supply has multiple terminals accepting at least one paired wire connection to the bright white LED light fixtures, this multiple terminal low voltage power supply capable of direct wiring to an AC electrical junction box in a wall or ceiling.

3. The device as disclosed in claim 1, wherein the bright white LED light fixture is flush mounted to a ceiling, including a flush mounted ceiling housing, at least one bright white LED light source, a reflective backing plate above the bright white LED light source, and a colorized diffusion panel below the bright white LED light source, also having a paired wire connection connecting to a pair of attachment terminals on the multiple terminal low voltage power supply.

4. The device, as disclosed in claim 1, further including a colorized diffusion panel, having a dense colored dot matrix of green, blue yellow and red transparent color dots, positioned in front of the bright white LED light source, providing the bright white LED light source with a more full color spectrum of visible light.

5. The device, as disclosed in claim 1, wherein the auxiliary power terminal is attached to a length of DC wire, connecting the device to an alternate DC power supply.
