The invention describes a flexible lighting strip comprising a multitude of light-emitting diodes arranged in at least two groups. Each group comprises at least two light-emitting diodes arranged in an electrical series connection. The at least two groups are arranged in parallel to an anode track and a cathode track. The at least two groups are arranged in a longitudinal arrangement such that a last light-emitting diode of a first group is arranged next to a first light-emitting diode of a second group. The anode track and the cathode track each consist of a wire line having substantially circular wires that are bent to receive compressive and/or tensile stress. The electrical circuit provides a third wire line having a substantially circular wire as a center line arranged between the outer lines. At least one light-emitting diode of every group is mounted on an interposer which contracts all three wire lines.

Flexible light-emitting diode lighting strip with interposer

Lighting device, in particular for automotive lighting applications, comprising a plurality of lighting elements arranged in one or more rows in order to form a luminous band, wherein each lighting element comprises at least one or more light emitting diodes (LEDs). The plurality of lighting elements is divided into one or more segments, wherein the lighting elements within each segment are electrically connected in series or in parallel. The lighting device further comprises at least one contacting element providing current for the plurality of lighting elements, wherein at least a first contacting element provides current for a first group of segments such that groups of lighting elements are independently and dynamically controlled.

Lighting device

An LED lighting package is described that contains a first LED string with a plurality of series-connected light-emitting diodes and a first linear regulator arranged to determine the current through the first LED string. At least one further LED string includes a plurality of series-connected light-emitting diodes of a different color, and a further linear regulator is arranged to determine the current through that LED string. The different colored LED strings are connected in parallel. A common voltage supply is used for the LED strings. The number of light-emitting diodes in the first LED string exceeds the number of light-emitting diodes in each further LED string (, and the number of light-emitting diodes in each LED string is chosen such that the total forward voltage of a further LED string is essentially the same as the total forward voltage of the first LED string.

LED lighting package

A modular LED string, an LED lighting assembly containing the LED string, and a method of manufacturing the lighting assembly are described. In various embodiments, the LED string contains LED module groups mounted on a carrier. Each module group has a series-connected row of LED modules, commencing with a first LED module followed by at least one inner LED module and terminated by a final LED module. Each main contact pad is electrically connected to a main supply track formed on the carrier and is arranged between neighbouring modules. Each secondary contact pad is electrically connected to a secondary supply track formed on the carrier and is arranged on either side of an inner module. An anode contact of each first module is electrically connected to the main supply track, and an anode contact of each remaining module is electrically connected to a secondary supply track.

A holder for a vehicle signaling light and a vehicle signaling light assembly are described. A holder for a vehicle signaling light includes a carrier rail with a hollow section. The carrier rail is coupled with at least two guiding structures. The guiding structures are arranged to guide a flexible light distribution fiber within the hollow section.

Holder for vehicle signaling light

The invention relates to a lighting device comprising at least two light-emitting elements and a method of producing a lighting device. The light-emitting elements are connected with each other into a module via a connection element. The connection element has at least one region spaced apart from the at least two light-emitting elements. At least two modules are connected with each other in parallel. The at least one region of the connection element has a specific electrical resistance that compensate differences between electrical characteristics of at least two light-emitting elements.

Lighting device and method for production thereof

The invention describes an illuminant for a vehicle headlight comprising a carrier and an electrical driver. Mounted on the carrier are a high-beam LED, a low-beam LED and a vehicle light detector. Additionally, a mechanical interface is included for mounting the illuminant in a corresponding socket of the vehicle headlight in a detachable way, and an electrical connector for supplying electrical power to the electrical driver. The electrical driver is arranged to receive vehicle light detection signals from the vehicle light detector to determine vehicle light by means of the vehicle light detection signals, and to provide a drive current to the high-beam LED or the low-beam LED depending on the determined vehicle light. Illuminant is further arranged to detect ambient light other than the vehicle light, such detection of ambient light influencing electrical driver in controlling the LEDs.

A lighting system includes a plurality of lighting units. Each lighting unit includes a unit control circuit and a lighting element. The unit control circuit is disposed to store at least one lighting scenario. The lighting scenario comprises a succession of settings of intensity and/or color of the lighting element. A system control circuit is disposed to transmit an execute signal to one or more of the lighting units. The unit control circuit is disposed to control, upon reception of the execute signal, the lighting element according to the lighting scenario. The lighting units are connected to a common electrical power supply via two conductors. The execute signal is transmitted from the system control circuit to the lighting units wirelessly or via the two conductors.
