Abstract: The Multi-MOEMS display comprises at least two MOEMS, and at least one superposition layer. All MOEMS are illuminated by beams which incide with incidence angles larger than the deflection angle onto the mirrors in their ON-state for an improved separation of illumination and reflected modulated beams. The reflected ON-beams accordingly include a zenith angle with the normal of the mirror arrays of the MOEMS. The increased angle between the illumination and the modulated beam facilitates the separation of illumination and modulated beams and diminishes the optic limitations of light energy flux through this reflection at the modulators. The Multi-MOEMS display uncovers a solution for the geometric problems of arranging multiple MOEMS and superposition layers posed by the non-normal reflection of the modulated image beams, by matching the zenith angles and the azimuth angles in the superposition image, and by a defined position of the MOEMS relative to the superposition layer.

Abstract: The present invention relates to color generation in an indoor or outdoor lighting device, and more particularly to a control method which provides spatially consistent color control of a lighting device designed for use in, e.g., spatially extended premises or environments containing obstacles, and thus including multiple light sensors to allow efficient control.
