The fly-eye lens includes micro lens units corresponding to the light-emitting diode chips, and for at least one light-emitting diode chip of the light-emitting diode chips, an image formed by each of at least one light-emitting diode chip on surfaces of the micro lens units is completely within a surface of one of the micro lens units. A ratio of side lobes is reduced, thereby improving the energy utilization rate.

An assembly for an opening through a member has a body and a first spring retention assembly coupled to the body. The first spring retention assembly has a first coil spring at least partially disposed within a first spring housing. The first coil spring has a first end extending through the first spring housing and is coupled to the body. The first coil spring is extendable from and retractable into the first spring housing.

A laser-excited-phosphor light-source system in which a phosphor plate remains stationary while a laser beam is made to scan across the phosphor plate. In some embodiments, the phosphor-plate assembly includes a plurality of areas each having a different phosphor substance that emits wavelength-converted light in response to excitation from the scanned laser beam and/or a diffusive material. In some embodiments, one or more rotating prisms and/or one or more rotating or oscillating or angularly displaced mirrors are used to deflect the input laser light on the way toward the phosphor plate and to deflect the wavelength-converted and/or diffused light in the opposite direction such that the output beam of wavelength-converted and/or diffused light remains stationary with respect to the phosphor plate as the input laser beam is moved across the surface of the phosphor-plate assembly.

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.Math.L1.Math.D/N wherein N is an integer with N≥1.
