Abstract: The illumination module for emitting light (5) can operate in at least two different modes, wherein in each of the modes, the emitted light (5) has a different light distribution. The module has a mode selector (10) for selecting the mode in which the module operates, and it has an optical arrangement. The arrangement includes—a microlens array (LL1) with a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P (P1);—an illuminating unit for illuminating the microlens array (LL1). The illuminating unit includes a first array of light sources (S1) operable to emit light of a first wavelength L1 each and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D1) from the microlens array (LL1). In a first one of the modes, for the lens pitch P, the distance D and the wavelength L1 applies P2=2·L1·D/N wherein N is an integer with N≥1.

Abstract: Various optoelectronic modules are described and include one or more optoelectronic devices. Each optoelectronic module includes one or more optoelectronic devices. Sidewalls laterally surround each optoelectronic device and can be in direct contact with sides of the optoelectronic device or, in some cases, with an overmold surrounding the optoelectronic device. The sidewalls can be composed, for example, of a vacuum injected material that is non-transparent to light emitted by or detectable by the optoelectronic device. The module also includes a passive optical element. Depending on the implementation, the passive optical element can be on a cover for the module, directly on a top surface of the optoelectronic device, or on an overmold surrounding the optoelectronic device. Methods of fabricating such modules are described as well, and can facilitate manufacturing the modules using wafer-level processes.

Abstract: Structured light projection system includes an array of light emitting devices, which is configured to emit a pattern of light. A projection lens is configured to receive and project the pattern of light from the array to a first optical element. The first optical element alters the pattern of light to generate a first emitted pattern of light that is irregular. The first emitted pattern of light is transmitted to a second optical element that is configured to receive the first pattern of light and reproduce the first emitted pattern along a second emitted pattern, which comprises multiple instances of the first emitted pattern arranged in a tiled pattern.

Abstract: This disclosure describes illumination assemblies operable to generate a patterned illumination that maintain high contrast over a wide temperature range. An implementation of the illumination assembly can include an array of monochromatic light sources positioned on an illumination plane, first and second optical elements, and an exit aperture. A chief ray of each light source within the array of monochromatic light sources can substantially converge at an exit aperture. In such implementations light generated by the array of monochromatic light sources can be used efficiently.

Abstract: An optical device (1) includes two prism bodies (41, 42) and four side panels (71-74) attached to both prism bodies (41, 42). A cavity (9) is thereby enclosed. A first reflector (81) can be present at a first side face (81) of the first prism body (41), and a second reflector (82) can be present at a second side face (82) of the second prism body (42). At least one of the prism bodies (41, 42) and/or at least one of the side panels (71-74) can be at least in part made of a non-transparent dielectric material such as a printed circuit board. In some implementations, an optoelectronic component (90) can be attached to the respective constituent of the optical device (1).
