Abstract
The illumination module for emitting light () can operate in at least two different modes, wherein in each of the modes, the emitted light () has a different light distribution. The module has a mode selector () for selecting the mode in which the module operates, and it has an optical arrangement. The arrangement includes—a microlens array (LL) with a multitude of transmissive or reflective microlenses () which are regularly arranged at a lens pitch P (P);—an illuminating unit for illuminating the microlens array (LL). The illuminating unit includes a first array of light sources (S) operable to emit light of a first wavelength Leach and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D) from the microlens array (LL). In a first one of the modes, for the lens pitch P, the distance D and the wavelength Lapplies P=2·L·D/N wherein N is an integer with N≥1.
