Disclosed is a power LED light source that can be employed with different reflectors and other additional parts to form various power LED light units. Compared with the power LED light unit utilizing Luxeon LED packages and the like, the disclosed invention has the advantages of higher power, lower costs, better heat dissipation design and simpler optical design. The power LED light unit comprises of a base metal ring with multiple power LED dies mounted on it, one or more reflectors connected to the base metal ring, one or more extend metal rings connected to the base metal ring, a light unit base connected to the last extended metal ring, and a control circuit inside the metal rings. Such designed power LED light unit can emit light patterns such as parallel light pattern, non-parallel light pattern, and ring light pattern.
