TUNABLE LED LAMP FOR PRODUCING BIOLOGICALLY-ADJUSTED LIGHT
First Claim
1. A tunable light-emitting diode (LED) lamp for producing biologically-adjusted light, comprising:
- a housing comprising a first cap positioned at a first end of the housing and a second cap positioned at a second end of the housing, each of the first and second ends comprising an electrical contact;
a power circuit disposed within the housing having electrical leads attached to at least one of the first and second caps;
a driver circuit disposed within the housing and electrically coupled with the power circuit; and
a plurality of LED dies electrically coupled to and driven by the driver circuit;
wherein the driver circuit is adapted to drive the plurality of LED dies to emit a phase-shift light having a first spectral power distribution, a general illuminating light having a second spectral power distribution, and a pre-sleep light having a third spectral power distribution;
wherein the phase-shift light is configured to affect a first biological effect in an observer;
wherein the pre-sleep light is configured to affect a second biological effect in an observer; and
wherein at least one of the first or second caps is adapted to couple with a tombstone associated with a troffer fixture thereby positioning the first or second cap in electrical communication with the tombstone.

Abstract
A tunable LED lamp for producing biologically-adjusted light having a housing, a power circuit, a driver circuit disposed within the housing and electrically coupled with the power circuit, and a plurality of LED dies electrically coupled to and driven by the driver circuit. The driver circuit may drive the plurality of LED dies to emit a phase-shift light having a first spectral power distribution, a general illuminating light having a second spectral power distribution, and a pre-sleep light having a third spectral power distribution. The phase-shift light may be configured to affect a first biological effect in an observer, and the pre-sleep light may be configured to affect a second biological effect in an observer. The LED lamp may be configured to fit in a troffer fixture. The LED lamp may also be a troffer fixture.
