    摘要: A method of retrieving status information of a lighting system includes propagating a command signal from a controller to a node of the lighting system by operating upstream transceivers that are upstream of the node in a transmitting mode and operating downstream transceivers that are upstream of the node in a receiving mode; propagating a reply signal including the status information of the LED unit of the node from the node to the controller by operating the upstream transceivers that are upstream of the node in a receiving mode and operating each of the downstream transceivers upstream of the node in a transmitting mode and reversing an operating mode of an upstream transceiver of a network segment from operating in a transmitting mode to operating in a receiving mode only when the downstream transceiver is operating in transmitting mode.

    摘要: A controller for controlling an LED assembly is described. The controller is arranged to—receive an input signal representing a required characteristic of the LED assembly,—convert the input signal to a control signal for the LED assembly,—apply a correction to the control signal to obtain a corrected control signal, the correction being based on a predetermined transient characteristic of the LED assembly,—output the corrected control signal. As such, a better correspondence between a required characteristic and an actual characteristic of the LED assembly is obtained.

    摘要: An LED driver measures a voltage across the LED and a temperature associated with the LED. The LED driver drives the LED to operate below a knee in the voltage/current curve of the LED and derives an expected voltage across the LED from the temperature of the LED, the LED driving current, and a predetermined relation between the expected LED voltage and at least one of LED temperature and LED driving current. The LED driver determines if the measured voltage across the LED exceeds the expected voltage across the LED, and establishes, based on the determination, if an LED approaching end of life warning is to be generated. Thus, an approaching end of life may be determined by the LED driver while the LED is still operational.

    摘要: A modular system includes an LED driver and an LED light engine. The driver includes a switched mode power converter and a first control unit to control a switch of the converter, thereby controlling the supply current to an LED assembly of the light engine. The assembly includes LEDs and one or more switches arranged in series or in parallel with one or more of the LEDs. The light engine also includes a second control unit controlling the one or more switches of the LED assembly so as to control current through the LEDs. The first control unit controls amplitude of the supply current. The second control unit controls duty cycle of the LED current through the LEDs. The first and second control units are configured to synchronize a switching operation of the switched mode power converter with a switching operation of the switches of the light engine.
