  • MAXIMIZING THE LIGHTING EFFICIENCY OF LED LAMPS
    Publication number: 20140110096
    Abstract: Disclosed is a method of making an LED light bulb using a plurality of surface mount light emitting diodes mounted on a variety of semiregular polyhedrons and optimizing the number and placement of the surface mount light emitting diodes for the widest lighting angle (to achieve as close to 360-degrees in three dimensions) with a heat sink matched to the thermal output of the surface mount light emitting diodes and the heat conductive capacity of the polyhedron. Also described are a light emitting diode light bulb made using a plurality of surface mount light emitting diodes mounted on a variety of semiregular polyhedrons. Some embodiments may include a heat conductor comprising a plurality of curved-T shaped heat fins.
