Abstract:
1. A light emitting diode (LED) light bulb comprising: a plurality of LEDs mounted on a LED mounting surface in a light bulb, said LEDs being in electrical communication with an electrical contact adapted for connection to an electrical power source; and a refractor/reflector comprising a narrow end and a wide end, the narrow end being reflective and mounted in and extending to said LED mounting surface such that said LEDs are positioned peripherally around and outside the narrow end of said refractor/reflector, wherein the narrow end of said refractor/reflector is centrally positioned with respect to said LEDS, said LEDs being adapted to emanate light rays, in a direction away from and opposite to said electrical contact, towards a curved surface of said refractor/reflector, wherein the curved surface of said refractor/reflector is adapted to reflect outwards the light rays emanating from said LEDs, wherein the curved surface is concavely curved with respect to said LEDs and curved outwards from the narrow end towards said wide end, and at least one LED mounted in the wide end of the refractor/reflector and in electrical communication with said electrical contact.
