How it Works
Light rays diverge from multiple sources (LEDs, etc.) to bounce off interior reflective surfaces, after which the light rays merge to travel in parallel as fused collimated beam.
Beam divergence angle is set by diffraction and source diameter divided by reflector focal length. Spill or stray light lost out of collimated beams is minimized by matching LED emission angle to reflector F/#.
Light rays are evenly distributed.
Low divergence beams reduces artifacts (source shadowing, hotspots, etc).
Low divergence enables illuminating targets at farther distance.
Mounting LEDs in position behind the sidewall controls glare by preventing the observer from seeing the emission surface on the LED directly at most angles.
