    • A condensing system and method with a plurality of LEDs is disclosed. The LEDs are positioned on the same plane. A first condensing lens is disposed at front of each LED, a second condensing lens is disposed at front of each first condensing lens, a third condensing lens is disposed at front of each second condensing lens, and a fourth condensing lens is disposed at front of all the third condensing lenses. After the light emitted by each LED is condensed by the corresponding first condensing lens, second condensing lens and third condensing lens, the divergence angle of the light becomes smaller, forming a bunch of nearly parallel light beams. The bunches of nearly parallel light beams simultaneously transmit through the fourth condensing lens, and then combine. The condensing system can be used as the light source with imaging lenses disposed therebehind to form an imaging system.
    • 公开了一种具有多个LED的冷凝系统和方法。 LED位于同一平面上。 第一聚光透镜设置在每个LED的前方,第二聚光透镜设置在每个第一聚光透镜的前面,第三聚光透镜设置在每个第二聚光透镜的前面,第四聚焦透镜设置在 所有第三个聚光透镜。 在由每个LED发射的光被相应的第一聚光透镜,第二聚光透镜和第三聚光透镜聚光后,光的发散角变小,形成一束几乎平行的光束。 几乎平行的光束的束同时透过第四聚光透镜,然后组合。 聚光系统可用作光源,成像透镜配置在其上以形成成像系统。
