The invention relates to a beam-forming array for projecting a divergent isotropic cloud of light points. The array comprises a source (4) for emitting electromagnetic radiation, a receiving or connecting possibility for a power source (2), an electrical or electronic subassembly (5), and an optical unit (6) that is arranged in a housing (1) along with the radiation source (4). The radiation source (4) is a semiconductor diode laser or a light emitting diode (LED) while the optical unit (6) is composed of at least two superimposed and grid-shaped spectral films that are offset relative to each other or a diffractive optical element. The optical unit (6) limits the intensity of the emitted radiation and the distance of the light point beams relative to one another to a value that does not pose any risk to a human eye. The invention has the advantage of providing a miniature portable array that is inexpensive to produce and easy to handle for a large spectrum of indoor and outdoor uses in order to project any clouds of light points, particularly of real constellations.
Beam-forming array for the projection of a divergent isotropic cloud, comprising a semiconductor diode laser (4) for emitting electromagnetic radiation, a pick-up or connection possibility for an energy source (2), an electric or electronic component (5), an optical unit (6) for the modulation of the radiation emitted by the semiconductor diode laser (4), and grid-shaped spectral films placed out of phase at an angle of 45° and/or 22.5° and/or 11.25° and/or 5.625° and/or 2.8125° in front of the optical unit, whereby the optical unit (6) and the radiation source (4) are contained in a housing (1), wherein
