Abstract

An example system includes a light source coated with a phosphor layer, a laser emitter to output a laser beam, and a controller to control a direction of the laser beam so that the laser beam hits a location on the phosphor layer. The laser beam excites the location on the phosphor layer to produce a spotlight at the location.
