| Title: |
Broad Spectrum Light Source Calibration Systems and Related Methods |
| Abstract: |
Systems and methods are disclosed for light sources that use the
photo-sensitivity of one or more colored LEDs to determine at least a
portion of the emission spectrum of a white light source or other broad
spectrum light emitter. As described herein, a white LED or other broad
spectrum light emitter can be used as the light source, if desired, along
with one or more additional colored LEDs, and the same colored LEDs can
be used to emit light and to adjust a color point produced by the light
source. Applications for the disclosed embodiments include but are not
limited to general lighting, LCD backlighting, projectors, and direct
emission displays such as OLEDs and digital billboards.
