Abstract
An apparatus, system, and method for lighting effects, including simulating a flame. A three dimensional carrier includes an array of a plurality of light sources distributed on it. A control circuit coordinates on/off of the light sources in a manner to simulate a jumping flame. In one embodiment, the three dimensional carrier and LEDs are encapsulated in an at least partially light transmissive cover. This light modular engine includes a control circuit and an interface to electrical power. The system can include the light engine in a light fixture such as an architectural fixture. The methodology can include a sequence of on/off and brightness variations for the array of light sources.
