Abstract
A low profile LED lamp bulb with high efficient heat dissipation is disclosed. Each of the lead frame unit has a top-down tapered metal section on bottom end adaptive for being bent inwards to form a lead frame bottom cup suitable for fitting in the low profile LED lamp. A modification embodiment is that a heat sink independent from electrode is attached to a backside of the lead frame with nonconductive adhesive material, heat and electricity are independent from with each other, so that no interference between heat and electricity, and heat can be dissipated mainly from the heat sink.
