| Title: |
System and Method for Regulation of Solid State Lighting |
| Abstract: |
Exemplary embodiments of the invention provide a system, apparatus, and
method of controlling an intensity and spectrum of light emitted from a
solid state lighting system. The solid state lighting has a first emitted
spectrum at full intensity and at a selected temperature, with a first
electrical biasing for the solid state lighting producing a first
wavelength shift, and a second electrical biasing for the solid state
lighting producing a second, opposing wavelength shift. Exemplary
embodiments provide for receiving information designating a selected
intensity level or a selected temperature; and providing a combined first
electrical biasing and second electrical biasing to the solid state
lighting to generate emitted light having the selected intensity level
and having a second emitted spectrum within a predetermined variance of
the first emitted spectrum over a predetermined range of temperatures.
