Abstract: The present invention provides a method and apparatus for determining intensities and peak wavelengths of light. The apparatus comprises one or more pairs of sensing units for sensing the light, a first sensing unit of a pair configured to sense a first intensity of the light in a first predetermined wavelength range with a first predetermined spectral responsivity and a second sensing unit of a pair configured to sense a second intensity of the light in the first predetermined wavelength range with a second predetermined spectral responsivity. The apparatus further comprises a processing system operatively connected to the one or more pairs of sensing units; the processing system configured to determine the intensity and peak wavelength for each of the one or more predetermined wavelength ranges of the light according to one or more predetermined functional relationships between each of the first intensity and second intensity.

Abstract: 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.

Abstract: The present invention provides an apparatus and method for characterizing the photometric and/or colourmetric properties of a light source. The apparatus comprises a detector system which generates data indicative of at least spectroradiometric data for at least a portion of the light emitted by the light source. The apparatus further comprises a manipulation stage configured to control the relative position between the detector system and the light source. In addition, the apparatus comprises a control and processing system configured to control operation of the detector system, operation of the manipulation stage and record the data and the relative position of the detector system associated therewith. The control and processing system is further configured to process the collected data for determination of the photometric and/or colourmetric properties of the light emitted by the light source.

Abstract: 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.

Abstract: The present invention provides a light source, method, computer-readable storage medium and computer program product for optimising one or more illumination characteristic thereof. In particular, the present invention provides a light source comprising four or more light-emitting elements, or groups or arrays thereof, each one of which having a respective predefined emission spectrum which, when combined in accordance with a given intensity ratio, provide illumination at a particular color temperature. This light source may comprise an internal and/or external selection module for selecting one or more illumination characteristics to be optimised, and internal and/or external computing module for optimising drive parameters of the light source to provide the optimised illumination characteristic selected. The light source may optionally be hardwired to operate according to predefined drive parameters selected, using a method, computer-readable storage medium and/or computer program product of the present invention, in order to optimise a pre-selected illumination characteristic.

Abstract: The present invention provides a light source for producing a substantially balanced output at a substantially optimised output intensity. In one embodiment, the light source comprises one or more light-emitting clusters of a first type and one or more light-emitting clusters of one or more other types, each one of which comprising one or more light-emitting elements, such that, when all light-emitting elements are driven to provide a substantially optimised output intensity, the spectral output of the one or more light-emitting clusters of the first type is substantially balanced by the spectral output of the one or more other light-emitting clusters.
