For example, actuators having a stacked diaphragm configuration may be used to increase maximum displacement of a light source and/or reflector assembly. In the present invention, an electronic control system is used to afford the smooth motion of the lens element. Advantages of the electroactive polymer module 10 include providing smooth motion, consuming significantly less battery life, and suitability for customizable design and performance options. For example, at least half of the light emitted from light source 806 is designed to hit primary reflector 812 first and be reflected in the desired direction without the necessity of being diverted by secondary reflectors. In any case, primary reflector 812 is designed to do the bulk of the variable direction ray reflection. 8A and 8B is one that couples the reflector assembly, or one or more reflectors/lenses thereof, to the electroactive polymer actuator to adjust its position relative to the light source(s).

Light emitted from the LED system across the translucent member can subsequently uniformly cover the surface. An electroactive polymer actuator slides an output plate 12 (e.g., sliding surface) relative to a fixed plate 14 (e.g., fixed surface) when energized by a high voltage. FIGS. 8A and 8B illustrate a schematic representation of an exemplary arrangement of such a lighting system 800. Here, a single-phase, single frustum-type electroactive polymer actuator 802 is employed which includes a diaphragm 808 affixed to a frame 810. The diaphragm may be weighted with a cap 842 having a selected mass to achieve the desired resonance frequency of the diaphragm. The electroactive polymer actuator may be moved at different frequencies for different light effects. The actuator module 21 is activated by coupling the battery 22 to an actuator circuit 29 by closing a switch 28. The actuator circuit 29 converts the low DC voltage VBatt into a high DC voltage Vin suitable for driving the module 21. The actuator circuit 29 may also comprise electronics components including microprocessors, memory, and signal generators, capable of generating specific patterns or waveforms or voltage drive signals to drive the motion of the actuator module 21. When the high voltage Vin is applied to the conductive electrodes 24A, 24B the elastomeric dielectric 26 contracts in the vertical direction (V) and expands in the horizontal direction (H) under electrostatic pressure.

In some embodiments, the display may include a layer of phosphors placed between the LED light sources and the lens stack. 1, many of the design variables of the module 10, (e.g., thickness, footprint) may be fixed by the needs of module integrators while other variables (e.g., number of dielectric layers, operating voltage) may be constrained by cost. Since actuator geometry-the allocation of footprint to rigid supporting structure versus active dielectric-does not impact cost much, it is a reasonable way to tailor performance of the module 10 to an application where the module 10 is integrated with an optical device.

The motion regimen should preferably be matched with the artwork to create the proper intended visual effect. The contraction and expansion of the elastomeric dielectric 26 can be harnessed as motion. 1, the top plate 12 of the module 10 comprises a sliding surface that mounts to an inertial mass or back of the optical system that can move bi-directionally as indicated by arrow 16.
