First Claim
Patent Images
1. An actuator system for a lighting system comprising:
- a shape memory alloy coupled to a component of the lighting system to control an actuation of the component and thereby produce a plurality of light patterns; and
an electrical control circuit in electrical communication with the shape memory alloy to selectively provide an electrical current to the shape memory alloy for controlling a physical property of the shape memory alloy and thereby the motion of the component of the lighting system.

8. A light control system comprising:
-
a light source for emitting a plurality of light rays; a beam modifier disposed in a path of the light rays for creating a light pattern; a shape memory alloy coupled to at least one of the light source, the beam modifier, and a static surface, wherein the shape memory alloy controls the motion of at least one of the light source and the beam modifier; and
an electrical control circuit in electrical communication with the shape memory alloy to selectively provide an electrical current to the shape memory alloy to cause a motion of the shape memory alloy and thereby the motion of at least one of the light source and the beam modifier to modify the light pattern created by the beam modifier. - View Dependent Claims (9, 10, 11, 12, 13)

14. A light control system comprising:
-
a light source for emitting a plurality of light rays; a beam modifier disposed is path of the light rays for creating a light pattern; and an actuator system including;
a main body having an attachment portion and a guide portion, wherein the attachment portion is coupled to the beam modifier;
an actuator guide having a cavity formed therein for receiving the guide portion of the main body to direct a motion of the main body;
a biasing device disposed between the main body and the actuator guide;
a shape memory alloy coupled to the main body and at least one of the actuator guide and static surface, wherein the shape memory alloy controls the motion of the main body and thereby a motion of the beam modifier; and
an electrical control circuit in electrical communication with the shape memory alloy to selectively provide an electrical current to the shape memory alloy for controlling a physical property of the shape memory alloy and thereby the motion of the main body. - View Dependent Claims (15, 16, 17, 18, 19, 20)
