Abstract: The present invention provides an extension to a standard N-bit digital pulse width control method which can discriminate 2N discrete pulse widths per pulse cycle. The present invention provides a method and apparatus that can modulate the pulse widths over a period of 2M pulse cycles in which each pulse cycle can have its own pulse width or respective duty cycle. The resulting time averaged or effective pulse width therefore can be controlled with a resolution of 2N+M states rather than a resolution of 2N states as is common with standard methods.

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 a light source comprising one or more light-emitting elements, one or more photosensors and, a photosensor light guide, such as, for example, a substantially planar light guide. The photosensor light guide is generally configured to capture and guide some of the light emitted from the one or more light-emitting elements to one or more photosensors optically coupled thereto, the light sensed thereby being useable as a basis for controlling the respective outputs of the one or more light-emitting elements.

Abstract: The present invention provides an integrated power and control unit for use with a solid-state lighting device. The integrated power and control unit comprises a power input and a data input. The power input receives power fro m a power source, wherein this power is configured in a first power format and the data input receives control data from a control data source, wherein the control data is configured in a first data format. The integrated power and control unit further comprises a translation device coupled to the power inp ut and the data input. The translation device is configured to convert the powe r in the first power format to power in a second power format and further configured to convert the control data in the first data format to control data in a second data format. The second power format and second data format are compatible with the required power and data formats of the solid-state lighting device and transmit the required power and data formats of the soli d- state lighting device using a power and data output.

Abstract: The present invention provides a drive and control apparatus provides a desired switched current to a load including a string of one or more electronic devices. A voltage conversion means, based on an input control signal converts the magnitude of the voltage from the power supply to another magnitude that is desired at the high side of the load. A dimming control means provides control for activation and deactivation of the load and may further provide a means for current limiting. A feedback means is coupled to the voltage conversion means and a current sensing means and provides a control signal to the voltage conversion means that is indicative of voltage drop across the current sensing means which represents the current flowing through the load. Based on the control signal received, the voltage conversion means can subsequently adjust its output voltage such that a constant switched current is provided to the load.

Abstract: The present invention provides a method and apparatus for controlling the thermal stress in lighting devices, for example light-emitting elements, that are exposed to large thermal gradients typically upon start-up, for example light-emitting elements operating in relatively cold ambient environments. The present invention provides an apparatus that can reduce this thermal stress, wherein the apparatus comprises a temperature determination mechanism for evaluating the temperature of the light-emitting elements prior to activation, and a control system to control the drive current such that it is gradually ramped up to the desired steady state peak current value, wherein the ramping of the drive current is dependent on the evaluated temperature of the light-emitting element.

Abstract: The present invention provides a thermally and electrically conductive apparatus that can provide both thermal conductivity and electrical conductivity for one or more electronic devices connected thereto. The apparatus comprises a thermally conductive element that is in thermal contact with one or more electronic devices and optionally in contact with a heat dissipation system. A portion of the thermally conductive element is surrounded by a multilayer coating system comprising two or more layers. The multilayer coating system includes alternating electrically insulating and electrically conductive layers in order to provide paths for the supply of electric current to the one or more electronic devices. A conductive layer of the multilayer coating system may be selectively patterned to connect to one or more electronic devices. In this manner, the combination of an electronic circuit carrier and a thermally conductive element can unify thermal conductivity with the provision of power and/or communication into a single integrated unit for use with electronic devices.

Abstract: The present invention provides a luminaire system and method for creating white light having a desired colour temperature. The system comprises one or more white light light-emitting elements for generating white light having a particular colour temperature. The system further comprises one or more first colour light-emitting elements and one or more second colour light-emitting elements. The luminaire system mixes the coloured light generated by the first and second colour light-emitting elements with the white light of a particular colour temperature, in order to create white light having a desired correlated colour temperature.
