TUNABLE LED LAMP FOR PRODUCING BIOLOGICALLY-ADJUSTED LIGHT |
摘要 |
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 pre-sleep light having a first spectral power distribution and a general illuminating light having a second spectral power distribution. 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. |

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 general illuminating light having a first spectral power distribution and a pre-sleep light having a second spectral power distribution; wherein the pre-sleep light is characterized by a blue output intensity level, in a visible spectral output range of between 380 nm and 485 nm, that is less than 10% of a relative spectral power of any other peaks in the visible spectral output above 485 nm; 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. |
