Abstract
The described embodiments relate to systems, methods, and apparatuses for controlling a lighting unit to provide multiple different static and dynamic illumination patterns. The illumination patterns can be provided in response to changes in environmental conditions detected by sensors of the lighting unit. For instance, the lighting unit can provide a flame-like illumination pattern when the sensor is detecting a first threshold amount of motion, and a static illumination pattern when the sensor is detecting a second threshold amount of motion. The flame-like illumination pattern can be expressed using multiple light guides that extend from the lighting unit and receive different colors of light that imitate the motion of a flame. The light guides can be, for example, cylindrical or pipe-shaped, and etched with different patterns to absorb and reflect incident light.
