Title: MEMS DEVICES FOR SMART LIGHTING APPLICATIONS
Abstract:
The invention provides a device comprising a movable micromirror adapted to receive light from one or more light source(s) and manipulate the reflected light. The micromirror can be actuated electrothermally. In particular, the micromirror is adapted to do at least one of: (a) tipping along a first axis; (b) tilting along a second axis; (c) changing focal length (i.e., varifocal mode); and (d) elevating (i.e., piston mode). The invention also provides a system comprising at least one device comprising a movable micromirror and at least one light source. The invention can be used in smart lighting applications.
