Title:
MICRO-OPTICAL BEAM-FORMING ARRAY FOR PROJECTING IMAGES OF A DIVERGENT ISOTROPIC CLOUD OF LIGHT POINTS, PRIMARILY FOR THE ENTERTAINMENT SECTOR
Document Type and Number:
WIPO Patent Application WO2008089729
Kind Code:
B1
Abstract:
The invention relates to a beam-forming array for projecting a divergent isotropic cloud of light points. Said 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.
