Abstract: A full color LED light for aircraft interiors is described, comprising a housing containing at least three differently colored groups of light emitting diodes, a controller for the groups of light emitting diodes and an alternating current power source. The controller distributes the alternating current to LED groups, providing a desired intensity of each differently colored group, producing a desired blended output color. At least one switching circuit receives input current from the power source, via the controller, and directs current to LED subgroups such that a near optimal voltage drop is maintained, given the varied voltage drops of the LED subgroups, regardless of the input voltage, in light of the voltage rating of the LEDs. Embodiments provide for measurement or estimation of current profiles, thermal profiles, and series resistance, allowing accurate measurement of lumen depreciation over time. Additional embodiments include a feedback circuit to temper input power fluctuations.
