Abstract:
1. A downlighting illumination system that maintains a high light output ratio greater than 0.75 with an extended apparent source size to provide a near uniform illuminance, correlated colour temperature (CCT) and colour rendering index (CRI) distribution across an illuminated area comprising: a power source to supply any one of a range of alternated current (AC) or directed current (DC) voltages; a means for controlling a power factor and a power quality to the system; a light emitting source with appropriate thermal conductivity and dissipation means; a reflector comprising a reflective inner surface having an input aperture and an output aperture and arranged to receive light from the light emitting source through the input aperture and to reflect the light through the output aperture in a manner that virtually extends an apparent size of the light emitting source to illuminate the output aperture; an electronic driving system to control light output characteristics of the light emitting source; a mechanical means for securing a position of the illumination system.
