A light-pipe lighting apparatus includes a light source with a collimating light pipe disposed adjacent the light source. An optical sheet is disposed adjacent the collimating light pipe opposite the light source. A mask is disposed adjacent the optical sheet opposite the collimating light pipe. A projection light pipe is disposed adjacent the mask and opposite the optical sheet. Light emitted from the light source is modified as it passes through the collimating light pipe, the optical sheet, the mask, and the projection light pipe thereby projecting an illuminated image. Based on patterns of transparent portions of the mask, corresponding patterns of illuminated images are projected from the light-pipe lighting apparatus.
A light source comprises an array of both white and amber LEDs. One or more light pipes are disposed adjacent the array of LEDs. An optical sheet is disposed adjacent the light pipe(s) wherein light modifying elements of the optical sheet are aligned perpendicular to the array of LEDs. During DRL activation, both white and amber LEDs illuminate, altering the output from a bluish-white to a warmer tone by integrating the amber LEDs with the white ones. The turn signal function exclusively illuminates the amber LEDs. This design significantly reduces the necessary number of white LEDs for a compliant DRL function while ensuring efficiency and an aesthetically pleasing lighting assembly in a compact space.

ENERGY-EFFICIENT LIGHTING SYSTEM FOR AUTONOMOUS VEHICLES
Disclosed are a system and a process for controlling the exterior lighting of an autonomous vehicle using autonomous modes of operation detected. In some modes, certain forms of exterior lighting normally required in manual operation are not necessary when the vehicle is in particular modes. Because of this, a control system is configured to dim or deactivate the headlights when one autonomous vehicle is following another autonomous vehicle. Similarly, taillights can be dimmed or turned off where an autonomous vehicle is leading another autonomous vehicle. This, in one respect, serves to conserve energy.
The present application discloses a light pipe assembly having a light pipe with a proximal end, an opposing distal end, a length between the proximal end and the distal end, and a surface, the surface having an emitting portion and an overlay portion, where the light pipe is a material capable of transmitting light with a first refractive index; and a reflective secondary surface having a second refractive index and a width, the reflective secondary surface positioned adjacent the overlay portion of the light pipe, where the first refractive index is greater than the refractive index of air, and the second refractive index is greater than the first refractive index. In at least one embodiment, the reflective secondary surface is a non-metallic material capable of reflecting light. In at least one embodiment, the width of the reflective secondary surface varies along the length of the light pipe.
