A light emitting diode (LED) circuit is disclosed having an LED having a plurality of current paths. A controller may be included for controlling the LEDs. The LED is connected to a first transistor and a first current sink to drive a constant current through the LED through a first current path. At least one cloning transistor can establish a parallel current path through the LED and parallel to the first current path and is connected such that the constant current in the first current sink is duplicated in the parallel current path.

Cloned constant current LED drive circuit and method for use

An integrated lighting insert is provided for multi-function automotive vehicle lighting that has minimal space requirements and provides different lighting functions in a single device with an electronic control module that can easily interface with vehicle electronics. The insert is a housing and a plurality of light transmission portions, a plurality of light sources integrated into the housing, each one configured for a different predetermined function associated with a particular use of, a condition of, or a state of the automobile. An electrical circuit is used along with a communications bus and individual controller circuits associated with the light sources for controlling the light functions.

Multifunction lighting module and its use

A light emitting diode (LED) circuit is disclosed haying a plurality of LEDs each having a respective current path. A controller may be included for controlling the LEDs. A first set of LEDs of the plurality of LEDs are connected to respective first set transistors and a first current sink to drive a constant current through each of the first set of LEDs and the first set of LEDs includes one or more LEDs, and the LED circuit may include at least one second set of LEDs of the plurality of LEDs that are connected such that the constant current in the first set of LEDs is duplicated. in the at least one second set of LEDs and the second set of LEDs includes one or more LEDs.
