A lighting assembly that efficiently collects and accurately directs light with a defined asymmetrical light ray angle distribution onto a nearby target surface. The light with the asymmetrical light ray angle distribution illuminates the target surface with a defined illumination profile. In theatrical and architectural lighting, the defined illumination profile is an even illumination profile on a nearly vertical surface. In street lighting, the defined illumination profile is an even illumination profile on a horizontal surface. The lighting assembly includes an LED and a solid reflector optic having a reflective surface shaped to reflect light from the LED in a way that produces the asymmetrical light ray angle distribution at least in part.
