Reflector for Projecting Collimated Light
Read on to see how it works
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.
Comparison to Conventional Optics
LEDs, halogen lamps, etc., are typically mounted at the bottom of a reflective bowl cup shape, or behind a refractive lens. Intensity dissipates with distance and light rays spill at all angles.
Increasing beam output with multiple sources is limited because side by side reflectors or lenses overlap so not all of each LED emission solid angle can be collected.
Novel Collimating Mirror Geometry
Threefold reflector geometry collimates a greater solid angle from LEDs, controls spatial distribution and intensity precisely compared to traditional in-plane optics.
