Abstract
A luminaire (12), such as an external light for an automobile or a wall sconce, includes at least first set of optical features (16B, 16F) and a second set of optical features (16A, 16C, 16E, 16G). The first set of optical features (16B, 16F) is configured for use with an LED bulb (10) emitting a first type of light emission pattern (20), such that the luminaire outputs a particular light emission pattern. The second set of optical features (16A, 16C, 16E, 16G) is configured for use with a bulb (10) emitting a second type of light emission pattern (24), such that the luminaire outputs a different type of light emission pattern. In this way, the same luminaire may output different light emission patterns depending on the emission pattern of the bulb. The luminaire's emission pattern may also be dependent on the color emitted by the bulb. Different bulbs may be used or different LEDs may be energized in a single bulb to generate the emission patterns.
