Abstract
A light engine comprises a plurality of light emitting diode (LED) devices arranged in a plane and a corresponding plurality of reflector cups wherein each LED device is disposed in a corresponding reflector cup and wherein the light engine does not include either a diffuser or a light mixing cavity. A directional lamp comprises the aforesaid light engine and an imaging lens arranged to generate an image of the light engine at about infinity. The directional lamp may further include a collecting reflector (for example, a conical, parabolic, or compound parabolic reflector) extending between a relatively narrower entrance aperture at which the light engine is disposed and a relatively wider exit aperture at which the imaging lens is disposed. The imaging lens may be arranged to generate a defocused image of the light engine at about infinity to soften the beam edge.
