Abstract: A multi-function lighting assembly provides multiple vehicle lighting functions (e.g., rear vehicle tail light and fog light) using a single printed circuit board substrate having mini or micro chip scale package LEDs or their unpackaged LED dies. LEDs for respective ones of the different lighting functions are separately controlled. LEDs controlled for respective functions can be interspersed, or disposed in different areas of LEDs having the same lighting function. A layer of optic components is disposed relative to the outputs of the LEDs and has different optic components for the LEDs of the respective lighting functions (e.g., collimator optics over LEDs controlled to provide a bright concentrated light output, and a diffuser over the LEDs controlled to provide a diffused light output). The multi-function lighting assembly can be employed as a universal board for seamless and convenient integration into various rear lamps having specific inner tail lenses.
