Coherent light rays reflecting device for e.g. extra large flat screen of computer, has reflecting mirror and two-way mirror bands forming closed square structure so that mirrors have reflecting side turned towards interior of structure

摘要

The device has color or power spectrum laser sources, three bands of reflecting mirrors and a band of two-way mirror, where the laser sources are disposed perpendicular to a non-reflecting side of the two-way mirror. The mirrors form a closed square structure, such that the mirrors have their reflecting side turned towards the interior of the structure.
