the invention for instance the reflector cavities 1 can be made as separate components and then separately joined to a common reflective combining chamber 2 turn now to the optical elements within device 20 one of the optical elements is a reflector 1 whose centerline is disposed in an angled orientation of device 20 as shown in the side cross sectional view of fig3 the light emitted from the led 10 represented by a light rays 6 and 7 passes through the aperture 30 of reflector 1 either reflecting off the surface 32 of reflector 1 and or combining chamber 2 or not the aperture 30 is sized to insure that essentially or substantially all light emitted by the led 10 and or reflected off of reflector 1 or reflected off the nearly cylindrical surface of combining cavity 2 is restricted to one half the acceptance angle 9 of a fiber 22 that may be placed at aperture 30 which in the illustrated embodiment is no more than 15 u00b0 off the optical axis of fiber 22 or the perpendicular axis of symmetry of aperture 30 the only exception is the light which is represented by ray 7 which reflects off the opposite wall of combining chamber 2 as represented by ray 8 some of the light which reflects off the opposite wall of combining chamber 2 will be within the acceptance angle of fiber 22 it is estimated that not more than ______ percent of the light emitted from aperture 30 will be outside the acceptance angle the reflective surface of reflector 1 can be coated to reflect substantially all of the peripheral light from light emitting diode led 10 which is held.
