Lens set design with array editability for extended light sources
摘要
Abstract
A lens set that can achieve large-area uniform light spot based on LED extended light source is designed by means of freeform surface method in combination with Snell's law and energy conservation.The lens set consists of a primary lens and a secondary lens.The primary lens regulates energy to achieve uniformity adjustment,while the secondary lens shrinks the LED luminous angle to reduce the lens set structure.The Monte Carlo ray-tracing simulation shows that a single lens set can achieve a square uniform spot on the receiving surface,with an effective light flux ratio of 95.5%and a uniformity illumination of 95.7%,indicating that the lens set equipped with LED source has excellent effective light flux ratio and illumination uniformity.While for lens array,simulation shows that it can also achieve a square uniform spot on the receiving surface,with an effective light flux ratio and uniformity greater than 95%,indicating that the lens set can be extended to the lens array adapted to planner multi-LED extended source.The results show that the designed lens set and lens array have promising potential applications in satisfying high-power light sources of the fluorescence-based inverse measurement devices.关键词
