1. An LED light bulb for use with a socket for incandescent bulbs, comprising:
- a bulb base, comprising a conductive socket with a first electrode at an apex of said socket, and a second electrode in electrical connection with a sidewall of said bulb base, with said electrodes configured to physically and electrically engage a standard light bulb socket configured for incandescent bulbs;
a globe base attached to said bulb base, said globe base configured for attachment of a globe, said globe serving to protect one or more LEDs from contact with foreign objects with said globe base having heat sink and heat transfer properties;
a control circuit including electronic components for powering and regulating electricity to an LED light;
at least one LED positioned inside said globe on said globe base, with said LED electrically connected to said first and second electrode by electrical connections, and configured to emit light when energized, with said LED in thermal contact with said bulb base, and said globe base;
an optic positioned over said LED, the optic comprising a lower portion with a generally conical outside profile, and an upper portion with a generally cylindrical outside profile, with said optic lower portion surrounded and supported by a support cone with a conical interior cavity, with an air space defined between said support cone and said optic lower portion;
said globe comprising air ventilation ports adjacent to said globe base, and at least one globe top air ventilation port, configured to permit air circulation of outside air into said globe interior, over said radiator heat sink fins, and out said globe top ventilation ports.

Abstract
Disclosed is a light bulb which utilizes LEDs which replaces an incandescent light bulb in a fixture for incandescent light bulbs. The LED light bulb includes an optic which can be shaped to direct light to the side, and in different directions from the LED light source. Heat dissipation structures include a heat transfer column which extends from the LED to the base of the bulb, and fins which surround the optic or the support cone around the optic. A removable cover is enclosed which has openings for air circulation within the globe of the light bulb.
