Abstract
A LED light fixture having a mixture of red and white LEDs, as well as any combinations of UVA, UVB, UVC LEDs. The ratio of outputs from these LEDs may be adjusted to achieve a desired germicidal effect. The light fixture is liquid-cooled using a cooling tube that directly cools the power supply and the LED flexible printed circuit.
Claims20
A LED (light-emitting diode) light fixture comprising:
- a LED flexible printed circuit, wherein said LED flexible printed circuit has a first array of high-power white LEDs to produce a first output of light;
- the LED flexible printed circuit having a second array of red LEDs to produce a second output of light;
- the LED flexible printed circuit having a third array of UV LEDs to produce a third output of light;
- wherein the third array of UV LEDs includes at least one of UVA LEDs, UVB LEDs, and UVC LEDs.

A method to sterilize surfaces and aerosols indoors for viruses, bacteria, or mold, the method comprising:
- activating a first array of high-power white LEDs in a LED light fixture to produce an output of light;
- activating a second array of red LEDs in the LED light fixture to produce an output of light;
- activating a third array of LEDs in the LED light fixture to produce an output of light, wherein the third array of LEDs having at least one of UVA LEDs, UVB LEDs, and UVC LEDs;
- wherein said first array, second array, and third array are disposed on a LED flexible printed circuit;
- adjusting a ratio of outputs of said first array:said output of said second array:said output of third array, to achieve a total output of light, which is defined as a luminous power flux.
