| 20120104974 | CONTROL UNIT FOR A LED ASSEMBLY AND LIGHTING SYSTEM - A control unit for a LED assembly includes a first and second LED unit, the LED units being serial connected. The LED assembly, in use, is powered by a switched mode power supply. The control unit being arranged to receive an input signal representing a desired output characteristic of the LED assembly, determine a first and second duty cycle for respective LED units associated with a nominal current of the switched mode power supply, for providing the desired output characteristic, determine the largest of the first and second duty cycles for respective LED units, determine a reduced current based on at least the largest of the duty cycles, adjust the first and second duty cycle for respective LED units based on the reduced current, and provide an output signal for the LED assembly and the switched mode power supply based on the adjusted first and second duty cycles and the reduced current for obtaining the desired characteristic. | 05-03-2012 |
| 20120014111 | LED LAMP COMPRISING LIGHT GUIDE INCLUDING FIRST AND SECOND DIFFUSING SURFACES - An LED lamp is described, the LED lamp comprising an LED unit, e.g. provided on a base, in an embodiment, a fitting for contacting a power supply, and a light guide arranged to receive a light beam from the LED unit and guide the light beam towards a first light diffusing surface thereby providing a diffused light beam and whereby the light guide further comprises a second light diffusing surface facing the first light diffusing surface for diffusing at least part of the diffused light beam. The LED lamp as described enables to provide an omnidirectional light distribution, comparable to the light distribution of a conventional filament based light bulb. | 01-19-2012 |

| 20110248644 | METHOD OF CONFIGURING AN LED DRIVER, LED DRIVER, LED ASSEMBLY AND METHOD OF CONTROLLING AN LED ASSEMBLY - A method of configuring an LED driver is disclosed. The LED driver being arranged to provide a supply current to an LED fixture comprising a plurality of LEDs. The method comprises: identifying the LED fixture (LF)1 sending via a communication network (NTW) a configuration request to a configuration database (DB), receiving configuration data from the configuration database; and configuring the LED driver (LPS) according to the configuration data. | 10-13-2011 |
| 20110148685 | CONFIGURABLE LIGHT FIXTURE, CONFIGURABLE LIGHTING SYSTEM AND METHOD FOR CONFIGURING A LIGHTING SYSTEM - A configurable light fixture for a lighting system is described. The light fixture comprising a receiver, wherein the receiver of the light fixture is arranged to, upon receipt of a pairing signal from a transmitter, store a transmitter ID comprised in the pairing signal in a first memory unit when the pairing signal is received within a pairing time window, the pairing time window being opened when the receiver is switched on from an off state, the receiver being arranged to, upon receipt of a control signal, compare a transmitter ID comprised in the control signal with the stored transmitter ID and release the control signal when the stored transmitter ID corresponds with the transmitter ID comprised in the control signal. | 06-23-2011 |
| 20110121757 | CONTROLLER FOR CONTROLLING AN LED ASSEMBLY, LIGHTING APPLICATION AND METHOD FOR CONTROLLING AN LED ASSEMBLY - 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. | 05-26-2011 |
| 20110115412 | POWER CONVERTER FOR AN LED ASSEMBLY AND LIGHTING APPLICATION - The present invention relates to a power converter for an LED assembly, the power converter comprising—a switched mode power supply arranged to power the LED assembly, an AC/DC converter arranged to provide a DC supply voltage to the switched mode power supply, a control unit arranged to receive an input signal representing a required load voltage for powering the LED assembly, the control unit being arranged to control the AC/DC converter based on the input signal. | 05-19-2011 |
| 20110084615 | LED ASSEMBLY, LED FIXTURE, CONTROL METHOD AND SOFTWARE PROGRAM - A plurality of LEDs arranged in groups, each group comprising at least one LED, a control circuit for driving the LEDs, the control circuit comprising a sensing device for sensing an operative parameter of the LEDs. The control circuit is arranged to: a) operate at least one group of the LEDs: b) sense by the sensing device a value of the operative parameter of the at least one group; c) repeat a) and b) for at least a different one of the groups; d) assign to each of the groups of LEDs a value of the operative parameter from the sensed operative parameter values; and e) control the driving of the groups of LEDs from the assigned operative parameter values. | 04-14-2011 |
