Abstract:
1. A solid state lighting (SSL) luminaire, comprising: a first plurality of light emitting diodes (LEDs); a second plurality of light emitting diodes emitting light with characteristics different from the first plurality of LEDs; and a current control mechanism configured to control the intensity of light from said first and second pluralities of LEDs, said current control mechanism capable of separately and disproportionately changing the emission intensity of said first and second pluralities of LEDs, such that said SSL luminaire emits light having desired characteristics; wherein said first and second pluralities of LEDs can be turned off by said current control mechanism; wherein one of said first or second pluralities of LEDs has higher emission efficiency than the other; and wherein said current control mechanism can turn off the one of said first and second pluralities of LEDs with lower emission efficiency.
