摘要： The present invention provides a method and apparatus for optical feedback control for an illumination device, wherein the control signal for each array of one or more light-emitting elements corresponding to a particular colour, is independently configured using a modification signal whose frequency is different for each colour. Electronic filters whose center frequencies are substantially equal to the modification signal frequencies of the drive currents for the light-emitting elements are used to discriminate between the radiant flux corresponding to each of the different colours of light-emitting elements, from a sample of the mixed radiant flux output collected by one or more optical sensors. The output of an individual electronic filter is substantially directly proportional to the radiant flux output of the light-emitting elements of the associated colour, which together with the desired luminous flux and chromaticity of the output light, the controller can use to adjust the control signals.

摘要： Disclosed herein are methods and systems for emitting light that can provide a desired light-induced physiological stimulus and a desired luminous stimulus. The light can be controlled to vary the physiological stimulus within a predetermined first range while maintaining the luminous stimulus within a predetermined second range that is useful for a number of self and/or space illumination applications. For example, an apparatus may include a controller for controlling the drive currents supplied to a plurality of light-emitting elements having different spectral characteristics, wherein the combination of currents is controlled such that the mixed light emitted is associated with the desired physiological and luminous stimuli.

摘要： The present invention provides a light source having an improved output optical quality. In general, the light source comprises one or more light-emitting elements in each of at least a first, a second and a third colour. The combined spectral power distribution of these light-emitting elements generally defines a spectral concavity. The light source further comprises a light-excitable medium configured and disposed to absorb a portion of the light emitted by one or more of the light-emitting elements and emit light defined by a complementary spectral power distribution having a peak located within the concavity. By combining the spectral output of the light-emitting elements with the spectral output of the light-excitable medium, an optical quality of the light source is improved.
