摘要： An IR sensor comprises a heat sink substrate (10) having portions (12) of relatively high thermal conductivity and portions (14) of relatively low thermal conductivity and a planar thermocouple layer (16) having a hot junction (18) and a cold junction (20), with the hot junction (18) located on a portion (14) of the heat sink substrate with relatively low thermal conductivity. A low thermal conductivity dielectric layer (22) is provided over the thermocouple layer (16), and has a via (24) leading to the hot junction (18). An IR reflector layer (26) covers the low thermal conductivity dielectric layer (22) and the side walls of the via (24). An IR absorber (30; 30') is within the via. This structure forms a planar IR microsensor which uses a structured substrate and a dielectric layer to avoid the need for any specific packaging. This design provides a higher sensitivity by providing a focus on the thermocouple, and also gives better immunity to gas conduction and convection.

摘要： A lighting unit comprises a packaging substrate (10) formed from a semiconductor, a channel (12) formed in the substrate and a discrete light emitting diode arrangement (34) in the channel. A surface region of the channel comprises doped semiconductor layers (20,24) which define a light sensor.

摘要： A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED whilst the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilise the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

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： 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.
