    • The present invention provides a method and apparatus for collecting and detecting light emitted from a plurality of light-emitting elements. The light-emitting elements are grouped into two or more clusters of one or more light-emitting elements with the clusters arranged such that a portion of the light emitted from each cluster is directly incident upon a central axis, wherein every point along the central axis is equidistant from each cluster. A light collection means also having a central axis associated therewith is placed such that the central axis of the clusters and the central axis of the collection means coincide. The light collection means collects a substantially equal portion of light from each cluster and propagates the collected light to a detection means comprising an optical sensor for conversion to an electrical signal representative of the light emitted by the clusters. The electrical signal provided by the light detection means may be fed back to a controller for use in controlling the properties of the light emitted by the light-emitting elements.

    • The present invention provides a system and method for controlling one or more light-emitting elements which are driven by forward currents to generate mixed light for use, for example, through a luminaire. The system has one or more light sensors for acquiring feedback optical sensor data and a user interface for providing reference data representative of a desired mixed light. The system also has a controller for transforming either the sensor data or the reference data into the coordinate space of the other and to determine a difference between the sensor and the reference data in that coordinate space. The controller is configured to adjust the forward currents during operating conditions so that the sensor data matches the setpoint data. The present invention also provides a system and method that can at least partially compensate certain temperature induced effects when transforming the optical sensor or the reference data.

    • 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.
