Abstract
\nA novel dynamic solid state lighting (SSL) module is
\ndemonstrated, allowing users to program the direction, brightness,
\ndivergence and shape of a projected white light in a variety of
\nlighting applications. The module is enabled by a fast beamsteering
\nMEMS mirror with high optical power handling. In order
\nto produce and project bright white light, the module illuminates a
\nphosphor target with a high power laser of several Watts. A
\nprojection lens projects the phosphor target into a cone of light of
\nup to 60\u00b0. This light projection is arbitrarily shaped and
\ndynamically programmable by controlling a MEMS mirror scan
\nhead to address specific portions of the phosphor target. An
\nadjustable focus lens in the scan head further allows control of
\nprojected beam divergence. Successful prototypes were
\ndemonstrated with both a single 445nm laser diode source (2.5W
\nlaser power) and with a dual (combined) laser diode sources
\n(5.5W laser power). While the prototypes have to date been limited
\nby available power of the laser sources, it is estimated that the
\nnovel MEMS mirror scan head design allows >10W (CW)
\noperation on a 2mm mirror without multilayer dielectric coatings.
\nThe introduction of dynamic laser beam steering is a paradigm
\nshift toward a new generation of solid state lighting (SSL) with
