  • Patent number: 8686660
    Abstract: An organic light-emitting diode (35) is described, which comprises a light-emitting structure designed to emit light when it is powered, and a delay structure designed to delay a propagation of at least two power signal pulses (4a_left, 4b_right, 4a_top, 4b_bottom) having a temporal relationship with one another and such a signal strength that a part of the light-emitting structure is driven in dependence on coincidence of the power signal pulses at said part of the light-emitting structure, and a terminal structure designed to receive the at least two power signal pulses (4a_left, 4b_right, 4a_top, 4b_bottom) and to feed the delay structure at its different positions with the at least two power signal pulses (4a_left, 4b_right, 4a_top, 4b_bottom). A circuit for powering said light-emitting structure, as well as a method of operating said organic light-emitting diode (35) is also described.

  • Patent number: 8552666
    Abstract: The invention relates to the controlling of a lighting system with a plurality of light sources, particularly to the semi-automatic commissioning of light sources of the lighting system or controlling of the creation of lighting scenes with the lighting system. A basic idea of the invention is to use a spatial coding of light for controlling a lighting system, particularly for commissioning of light sources of the lighting system instead of or in addition to the temporal light coding as applied in the prior art.

  • Patent number: 8492986
    Abstract: A circuit arrangement (1) for a light emitting device, comprising a first circuit branch (2) for receiving an AC voltage and comprising a first light emitting diode (LED) circuit (3) serially connected with a first phase-shifting element (4), a second circuit branch (12) connected in parallel with the first circuit branch, the second circuit branch comprising a second LED circuit (13) serially connected to a second phase-shifting element (14), in reverse order compared with the LED circuit and phase-shifting element in the first circuit branch, and a third circuit branch (22) comprising a third LED circuit (23) connected between the first and second branches. With such a circuit design, the current through the first and second LED can be phase shifted compared with the current though the third LED circuit, so that the first and second light emitting diode circuits emit light during one time period, while the third light emitting diode circuit emits light during a second period.

  • Publication number: 20110025230
    Abstract: The present invention relates to a driver device (10) for driving and controlling light emitting diodes (LEDs) or LED-strings comprising a control unit (16), and at least two switching units (14) coupled in series, and each comprising a switch (22) controllable by said control unit (16) and two connection points (30) for connecting at least one LED, wherein the first connection point (28) is coupled with one end of said switch (22). The driver device is characterized in that each switching unit (14.1 to 14.n) comprises an inductance coupled between the other end of said switch (22) and said second connection point (30).
