Abstract:
1. An apparatus for simulating a flickering flame effect, comprising: a housing including an interior space; a pendulum member pivotally mounted within the interior space, wherein the pendulum member includes first and second ends with a flame element extending from the second end such that at least a portion of the flame element extends outwardly from the housing and wherein the pendulum member is pivotally mounted within the interior space using a pendulum support member coupled to the housing; a first light source transmitting light onto the pendulum member; and a drive mechanism positioned at least partially in the housing and configured to generate chaotic motion of the pendulum member in at least two dimensions; and a drive circuit coupled to the drive mechanism and providing a time-varying signal to the drive mechanism that at least in part defines the chaotic motion of the pendulum member.
