Abstract:
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 generally cylindrical radiator section attached adjacent to said bulb base, said radiator section with at least one generally circular radiator fin circumvolving said bulb base, said radiator section for expelling heat from said bulb; a generally planar globe base attached to said radiator section, said globe base configured for removable attachment of a globe, and said globe base defining a plurality of openings for ventilation adjacent a globe base edge, with said globe comprising generally cylindrical sidewalls and a spherical top, enclosing an air space around LEDs, with an opening near said globe top and a plurality of openings in glove sidewalls, for air circulation by passive convection through said air space above said LED and inside said globe, with said holes providing air convection paths based on the principle of by warm air rising, when said light bulb is in any spacial orientation, said globe serving to protect said LED from contact with foreign objects and being removable from said globe base; a control circuit including electronics 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, said globe base, and said radiator section.
