Abstract
A vehicle lamp includes one or more LEDs mounted to a printed circuit board for producing light. One or more inner lenses are coupled to LEDs for receiving light such that light enters along an edge or surface of each inner lens and propagates through each inner lens before exiting. A projection lens is oriented adjacent the inner lenses such that the projection lens receives light from the inner lenses and projects the light from the vehicle lamp. A light blocking material is applied to at least a portion of the projection lens for altering an appearance of light emitted from the projection lens. The resulting projections provide custom lit appearances having varying patterns, intensity, texture, and/or color. The vehicle lamp may be used for satisfying vehicle lamp legal functions, welcome functions, autonomous driving functions, and/or logo functions.
