摘要： In one embodiment, a control system is for controlling a lighting system which comprises a cluster (20) of different colour LEDs. The control system comprises a first control unit (24) for generating amplitude values for the different LEDs of the cluster to provide a desired colour point and a second control unit (38) for controlling pulse width values for the different LEDs to provide a desired brightness. Current sources (32) are provided for individually driving the LEDs of the cluster. This system allows the control of colour point to be independent from the control of brightness of the LED cluster. This provides a low cost solution and a fast, accurate and flexible control to a LED cluster.

摘要： A method of operating a light emitting diode (1 ) comprises operating the light emitting diode to provide a desired brightness output and estimating the junction temperature of the light emitting diode based on electrical drive parameters of the light emitting diode. A threshold is derived which determines if there is overheating, and the light emitting diode is operated within the threshold. This method uses junction temperature estimation to implement a system which provides protection from overheating. The method allows an LED to be used at its maximum potential in term of light generation whilst avoiding the need for external temperature measurement.

摘要： The present invention relates to a manufacturing method of an integrated circuit (IC) comprising a substrate (10) comprising a pixilated element (12) and a light path (38) to the pixilated element (12). The IC comprises a first dielectric layer (14) covering the substrate (10) but not the pixilated element (12), a first metal layer (16) covering a part of the first dielectric layer (14), a second dielectric layer (18) covering a further part of first dielectric layer (14), a second metal layer (20) covering a part of the second dielectric layer (18) and extending over the pixilated element (12) and a part of the first metal layer (16), the first metal layer (16) and the second metal layer (20) forming an air-filled light path (38) to the pixilated element (12). The air-filled light path (38) is formed by creation of holes in the first dielectric layer (14) and the second dielectric layer (18), filling the holes with sacrificial materials, and removal of the sacrificial materials after deposition and patterning of the second metal layer (20). This yields an IC having a low-loss light path to the pixilated element (12). The light path may act as a color filter, e.g. a Fabry-Perot color filter.
