Abstract
The invention belongs to the technical field of optics, and particularly relates to a symmetrical structured LED light-total-reflection collimation system with theoretically lossless lighting effects. The collimation system includes an LED light source module, improved ellipsoid reflectors, improved first parabolic reflectors and improved second parabolic reflectors. A light source is arranged at the first focal points of the ellipsoid reflectors, the improved first parabolic reflectors are located below the ellipsoid reflectors, and the focal points of the first parabolic reflectors coincide with the second focal points of the ellipsoid reflectors; the focal points of the improved second parabolic reflectors are located at the light source, and the whole system is of a left-right mirror symmetry structure; part of the light emitted from the light source forms collimated light through the ellipsoid reflectors and the first parabolic reflectors, and the other part of the light forms collimated light through the second parabolic reflectors. Only the reflectors are used in the whole system, the dispersion of multispectral hybrid light is avoided, and effective light energy is high in utilization rate.
