  • Patent number: 10378732
    Abstract: Lighting applications which are particularly difficult to light because of “non-standard” target area characteristics or the like would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has reached a point of diminishing returns in terms of beam control. Envisioned is an LED lighting system designed for precision lighting insomuch that—as compared to state-of-the-art LED lighting fixtures—sharpness of cutoff is improved while in at least some cases simultaneously allowing a steeper cutoff without undesirable beam shift. Furthermore, overall beam dimensions can be tailored fixture-to-fixture for an application without replacing an entire optic system or designing an entirely new fixture, and control of intensity distribution is improved (e.g., by avoiding striations at the edge of beam patterns). Said envisioned LED lighting system employs a number of materials not used in conventional LED lighting systems in novel ways to achieve the aforementioned.
