Refracting elements, including ball lenses that concentrate and provide unobstructed optical pathways from multiple light sources

An optical system for use in various lighting products and applications, comprising:

• a chain of optical components, each component substantially aligned along a common optical axis, the chain including:
• a first component being an LED;
• a second component being a first optic being a substantially spherical ball lens that collects and projects light emanating from the LED as a concentrated beam;
• a third component being a second optic being a reflector, so disposed along the common optical axis to intercept and reflect the beam projected from the ball lens and oriented and positioned relative to the ball lens so as to reflect substantially all light from the concentrated beam away from the ball lens,
• wherein the reflector is mounted on a mechanical device capable of repositioning the reflector to redirect the concentrated beam projected from the ball lens optic.
