Symmetrical structured LED light-total-reflection collimation system with theoretically lossless lighting effects

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.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a theoretically non-destructive optical efficiency optical total reflection symmetric structure collimation system based on an LED light source. Background technique [0002] With the advancement of technology, LED, as a light source, has gradually been valued by people for its advantages of high efficiency, environmental protection, small size, and long life. At this stage, LEDs are more and more used in automotive lighting, household lighting, and commercial lighting. The design of the lamp structure for the LED light source is also becoming more and more diverse. [0003] Because LEDs have the characteristic of 180° single-sided light emission, traditional design structures using simple reflectors or lenses can only use part of the energy of LEDs, and the overall energy utilization rate is about 60%-70%. However, due to the low energy utilization rate, higher wat...

Problems solved by technology

[0003] Because LEDs have the characteristic of 180° single-sided light emission, traditional design structures using simple reflectors or lenses can only use part of the energy of LEDs, and the overall energy utilization rate is about 60%-70%.

However, due to the low energy utilization rate, higher wattage LEDs are required to achieve lighting effects, which not only fails to achieve the purpose of energy saving, but also makes the heat dissipation requirements of the entire lamp group higher, which is not conducive to the widespread promotion of LEDs.
