Abstract
A luminaire is providing, having a substrate of a particular shape and a plurality of solid state light sources mounted thereon. The plurality has a measurable characteristic and includes an adjustable solid state light source, such that the characteristic changes in response to adjustment thereof. The luminaire also includes a sensor that detects the characteristic from outputted light, compares it to a baseline value and, based on the comparison, so adjusts the adjustable solid state light source. The luminaire also includes a reflector with a lower edge that conforms to the particular shape of the substrate, and reflects outputted light from the plurality so that it exits past the reflector's upper edge. The luminaire also includes a lightguide having an input that is surrounded by the reflector and captures a portion of the outputted light so as to provide the captured outputted light to the sensor.
