| 20080215279 | Luminaire control system and method - 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. | 09-04-2008 |

| 20090189530 | METHOD AND APPARATUS FOR LIGHT INTENSITY CONTROL - 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. | 07-30-2009 |
| 20090196071 | LIGHTING SYSTEM FOR CREATING AN ILLUMINATED SURFACE - The present invention combines point light sources in combination with a light guide element and light redirecting elements into a system which can emit light across one or more extended surfaces of the light guide and may be designed to be able to emit light uniformly across the extended surfaces. The system comprises one or more light-emitting elements and a light guide in which are defined one or more voids.

Optically coupled to the light guide are a plurality of light redirecting elements for altering of the propagation of light through the light guide, thereby enabling light to be emitted from the surface of the light guide in a desired pattern, for example in a uniform illumination pattern. | 08-06-2009 |
