Abstract
There is provided a lighting device, comprising at least one light emitter, at least one reflector and at least one sensor. The sensor is positioned within a region which receives direct light from the light emitter when the light emitter is emitting light. In some embodiments, the light emitter comprises one or more light emitting diode. In some embodiments, the sensor is positioned between the light emitter and a power supply. In some embodiments, the reflector comprises at least one opening, and light emitted by the light emitter passes through the opening to the sensor. In some embodiments, the sensor is sensitive to only some wavelengths of visible light. Some embodiments are back-reflecting lamps, and some are forward-reflecting lamps.
