Problems solved by technology

At present, most LED optical collimation systems, because their structure only includes LED surface light source and aspheric lens structure, only through the improvement of mirror surface structure, can only realize close-range illumination, and the applicable LED surface light source also has great limitations.
For large-area LED surface light sources, the light efficiency utilization rate of the collimation system is low, and the divergence angle of the beam after collimation is too large, making it difficult to achieve long-distance lighting

Abstract

The invention discloses an LED remote illumination optical alignment system which comprises an LED surface light source, an aspherical lens and a Fresnel lens, wherein the aspherical lens is located between the LED surface light source and the Fresnel lens; the centers of the LED surface light source, the aspherical lens and the Fresnel lens are collinear; the distance between the LED surface light source and the aspherical lens is 0-10 mm, and the distance between the aspherical lens and the Fresnel lens is 100-1000 mm; with the adoption of the LED remote illumination optical alignment system, the light beam divergence angle can be controlled to minimum, the light source alignment effect and the utilization ratio are high, the system can be used for alignment of an LED surface source light with a large area, and long distance and high brightness lighting work is realized.

Description

technical field [0001] The invention relates to an illumination system in the field of illumination, in particular to an optical collimation system for LED remote illumination. Background technique [0002] As a new type of solid-state lighting source, LED has been widely used in the lighting field in recent years due to its outstanding advantages such as energy saving, short start-up time, high safety, long life, and environmental protection. With the emergence of high-power LEDs, long-distance outdoor searchlights are bound to become one of the development trends in the lighting field. [0003] The LED remote lighting optical collimation system collimates the divergent light of the LED surface light source, so that the illuminance of the target area meets the expected requirements. At present, most LED optical collimation systems, because their structure only includes LED surface light source and aspheric lens structure, can only achieve close-range illumination only thro...
