Abstract
Disclosed are various embodiments of system, devices, components and methods for controllably configuring the brightness and color of light emitted by an automotive LED illumination system. The brightness and color of light emitted by LEDs, or clusters or groups of LEDs, may be varied smoothly or in step-wise fashion to produce virtually any desired pattern of collimated light. Such a pattern may be varied in respect of time or space, or both time and space. Light and other types of sensors may be employed to provide feedback control as a further means of controllably configuring the brightness and color of light emitted by such a system in response to changes in external and other conditions.
