Abstract: A controller provides power to (i) a first light-emitting device that emits a first white light of a first correlated color temperature (CCT) and (ii) a second light-emitting device that emits a second white light of a second CCT. The second CCT is lower than the first CCT. The first and second white lights mix to yield a combined white light having a combined CCT with a combined brightness.

The controller distributes supply power to the first and second light-emitting devices according to a power-distribution scheme that differentiates between whether Vin is in an upper range or a lower range, as follows: (i) In the upper range: as Vin decreases, combined-light CCT decreases and combined-light brightness remains constant.

The PIR motion sensing unit is a two-portion design with a Fresnel lens either integrating with a light diffuser or as a separate piece positioned right behind the light diffuser and with a PIR motion sensor positioned at a focal point of the Fresnel lens and encircled by LEDs, wherein the Fresnel lens collects infrared ray signals generated by a moving body and remotely converges infrared ray signals on the PIR motion sensor. A signal processing circuitry decides whether the infrared ray signals represent an intrusion in order to turn on the compact lighting device. When the compact lighting device of this art is turned on, there is no shadow effect which reduces the lumens output of the security light.
