Abstract

An LED lamp is disclosed, comprising a base (1), an envelope (2) and a power source (3) inside the base. A metal housing (4) for heat dissipation, with its top portion located inside the envelope, is secured between the base and the envelope, and a heat dissipation substrate (5) is secured on the top of the metal housing. LED light emitting posts (6) are inserted and fixed into the heat dissipation substrate and each LED light emitting post comprises two printing circuit board (PCB) substrates containing LED chips mounted on both front faces. The LED chips are electrically connected to the PCB substrates, which are electrically connected to the power source. The two PCB substrates are closely fixed against each other by their back faces, between which a heat dissipation metal plate is sandwiched. The LED lamp can realize light emitting in a radial way and enable a large range of lumination and fast heat dissipation.
