  • Publication number: 20130320849
    Abstract: The invention relates to a device for operating a lamp, in particular in a vehicle, wherein the lamp is coupled to a controller for energy-related supply of the lamp, and a data channel is present between the controller and the control unit. It is inventively provided that the controller and the control unit exchange characteristic data of the lamp, in particular current parameter data, temperature protection data, socket current data, or the like via the data channel, and the controller has an indicator with an indicator value, wherein in the instant of a first initialization of the controller, the characteristic data can be transmitted from the controller to the control unit depending on the indicator value.

  • Publication number: 20120319603
    Abstract: The present invention relates to a method to supply power to an LED array, comprising at least two LED branches connected in parallel, in each of which at least one LED is arranged. The LED array is supplied with predetermined power from a current source connected in series, wherein currents are measured in the LED branches, wherein the measured currents are compared in control electronics, and wherein the currents are controlled in a part of the LED branches such that they have a defined ratio with respect to one another in the LED branches. The method is intended to be improved such that it can be carried out economically and with simple means. This is achieved in that one of the LED branches is selected to be the master whose current is utilized as the target specification for the remaining LED branches. The invention further relates to a circuit arrangement for implementing the method according to the invention as well as a lighting unit with such type of circuit arrangement.
