Patent ID: 8193688

Claim:
An LED (light emitting diode) lamp, comprising: a heatsink housing ( 2 ); an alternating current LED module ( 1 ) mounted in the heatsink housing; wherein the alternating current LED module includes a heat conducting portion ( 10 ) and two electrical connections ( 11 ); the heat conducting portion of the alternating current LED module is combined with the heatsink housing; the electrical connections of the alternating current LED module are electrically connected with an external power supply; the heatsink housing forms a nonmetallic porous structure with a great heat dissipation feature; the heatsink housing is formed to have the profile of a common lamp housing; the heatsink housing has a hollow inside provided with a receiving chamber ( 20 ) to receive the alternating current LED module; the LED lamp further comprises: a heat conducting plate ( 3 ) mounted between the heat conducting portion of the alternating current LED module and the heatsink housing; a conduction board ( 30 ) mounted between the heat conducting plate and the heatsink housing; the heat conducting plate is made of a metal having a great heat conductivity; the heat conducting portion of the alternating current LED module is encompassed by the heat conducting plate; the heat conducting plate separates the heat conducting portion of the alternating current LED module from the heatsink housing; the conduction board is made of a metal having a great heat conductivity; the conduction board has a top face abutting the heat conducting plate and a bottom face abutting the heatsink housing.
