Abstract:
1. An LED lamp assembly comprising: an axially extending stem having a base end, a distal end and an axial stem passage extending therebetween; at least one electrical lead extending in the stem passage; a rigid heat conductive plate having a first side and a second side; the plate being mounted on the distal end of the stem with the first side facing towards the base end; the plate extending transversely to the axis, the plate having a greater radial extension than a radial extension of the stem adjacent the mounting to the plate whereby the radial periphery of the plate overhangs the stem; electrical circuitry adjacent a side of the plate thereby forming a plate assembly; the plate assembly having a plate assembly passage; at least one LED attached to the plate assembly with the LED in electrical connection with the circuitry and in thermal connection with the plate; and a cap mechanically coupled through the plate assembly passage to the stem trapping the plate assembly between the cap and the stem.
