  • Systems and methods for adjusting light output of solid state lighting panels, and adjustable solid state lighting panels
    Publication number: 20070188484
    Abstract: A lighting panel includes a first circuit including a first LED configured to emit light at a first wavelength, a second circuit including a second LED configured to emit light at a second wavelength, and an adjustment circuit connected in parallel with the first circuit and configured to adjust a current through the first circuit. The adjustment circuit may include a trimmable resistor connected in parallel with the first circuit. Methods of manufacturing a lighting panel include mounting a plurality of lamps on a frame, each lamp including a first LED configured to emit light at a first wavelength and a second LED configured to emit light at a second wavelength, connecting selected ones of the first LEDs in a first circuit and selected ones of the second LEDs in a second circuit.
