Patent ID: 8300293

Claim:
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 the optical unit ( 6 ) comprises at least two grid-shaped spectral films placed on top of each other or out of phase or of a diffractive optical element, the optical unit ( 6 ) limits the divergently emitted beams in its intensity and in the distance of the light-point beams to one another at a certain value which does not represent a hazard for the human eye, whereby the power of a light-point beam ≦1 mW and, the radiation source ( 4 ) is a semiconductor diode with a power of at least 5 mW, preferably 10 mW to 500 mW.
