An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

LED lamp

A method of forming a light bulb core, and a light bulb or lamp incorporating the core. The method includes forming a heat sink having at least six working facets located equally on opposite sides of a central plane, and then mounting a light source on each of the working facets. The light sources are mounted on circuit boards, each circuit board corresponding to a respective one of the working facets. The boards are then applied to respective working facets. The bulb is composed of a screw base, an external heat sink mounted in the screw base, and the light bulb core mounted in and extending from the external heat sink. The light source comprises a plurality of light emitting diodes.

High intensity LED replacement of incandescent lamps

An LED lamp for replacement of directional incandescent lamps. The lamp comprises a screw base, a plurality of LEDs located in a first position, and a driver for the LEDs located in a second position separate from the first position. A lamp housing is secured to the screw base, with the LEDs and the driver being located in the lamp housing. A heat spreader is mounted in the lamp housing in proximity to the LEDs to remove heat therefrom. The heat spreader can also remove heat from the driver, or the driver can be located in proximity to the screw base and in thermal connection therewith so that heat is transmitted through the screw base.

LED lamp replacement of low power incandescent lamp

In an embodiment of the present invention, a light emitting diode (LED) recessed down light fixture comprises a housing, a reflector assembly mounted to the housing, and an LED circuit board attached to the housing over the reflector assembly. The LED circuit board includes a plurality of resistors electrically connected to the LED circuit board, a bridge rectifier, and a plurality of at least 80 miniature LEDs electrically connected to the LED circuit board and configured to provide light. The plurality of miniature LEDs are separated into a plurality of LED clusters. Each cluster is electrically connected to at least one resistor. Further, the plurality of miniature LEDs are arranged in a configuration such that a voltage differential across any two proximate LEDs is less than 36 volts. The down light fixture further comprises a lens cover attached to the top end of the reflector assembly.
