LED lamp with heat dissipation structure

摘要

An LED lamp comprises a supporting base, a number of heat dissipation structures, a number LEDs and a transparent envelope covering the heat dissipation structures and the LEDs therein. Each heat dissipation structure comprises a bottom plate and a lateral plate extending upwardly from the bottom plate. The bottom plates are mounted on a top surface of the supporting base and surround a regular shaped zone on the top surface of supporting base. The lateral plates spacingly surround the regular shaped zone. The lateral plates each comprises an inner surface facing the regular shaped zone and an outer surface facing away from the regular shaped zone. The LEDs each are mounted on the outer surface of the lateral plate of each heat dissipation structure.
