Abstract

Lighting device, in particular for automotive applications, comprising a plurality of lighting elements, wherein each lighting element comprises at least one or more light emitting diodes (LEDs). The lighting device comprises a first connector for connecting the lighting device to a lighting driver. The lighting elements are arranged in a row in order to form a luminous band. The plurality of lighting elements is divided into more than one group, each group consisting of at least one or more lighting elements. The lighting elements of one group are electrically connected in series. The groups are electrically connected in parallel in order to control each group individually.

Description

technical field [0001] The invention relates to a lighting device, in particular for motor vehicle applications, and a lighting system comprising such a lighting device. Background technique [0002] In the motor vehicle sector, it is currently a trend to implement lighting that can be dynamically controlled. This means that it is no longer sufficient that the lighting device can be switched on and off, instead the components of the lighting device must be individually adjustable. For example, individual components can be switched on and off or dimmed in order to create dynamic lighting effects. The availability of light-emitting semiconductors (LEDs) has greatly enhanced the development of light-emitting devices that can be dynamically controlled. [0003] The LEDs can be controlled individually by addressing each LED by separate electronic wires. However, this results in the need for numerous wires to be connected to the lighting driver in order to control each LED indi...
