Abstract

A lighting device, in particular for motor vehicle lighting applications, comprises a plurality of lighting elements arranged in one or more rows so as to form a light strip, where each lighting element comprises at least one or more light emitting diodes (LEDs). The plurality of lighting elements is divided into one or more sections, wherein the lighting elements within each section are electrically connected in series or in parallel. The lighting device also includes at least one contact element providing current to the plurality of lighting elements, where at least a first contact element provides current to the first set of segments such that the sets of lighting elements are independently and dynamically controlled.

Description

technical field [0001] The present invention relates to a lighting device, particularly for automotive lighting applications, and more particularly in the form of a lighting strip or lighting strip. Background technique [0002] In the field of motor vehicles, it is currently a trend to implement lighting devices that can be dynamically controlled. This means that it is no longer sufficient that the lighting device can be switched on and off, but in addition the components of the lighting device must be individually adjustable. For example, various components can be turned on and off or dimmed in order to generate 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 individually controlled by addressing each LED by separate electrical leads. However, this results in the need for numerous wires to be connected to the ligh...
