摘要： An LED lamp includes a first heat sink, a second heat sink and a plurality of LED modules. The second heat sink is located at a lateral side of the first heat sink and pivotally connects with the first heat sink. The LED modules are evenly attached on bottoms of the first and second heat sinks. The second heat sink can be rotated relative to the first heat sink to be fixed at a required position, whereby an illumination angle of the LED lamp can be adjusted. Heat generated by the LED modules is dissipated by the first and second heat sinks.

摘要： An LED lamp includes a hollow first heat sink (10), a plurality of LED modules (40) respectively mounted on outer sidewalls (120) of the first heat sink, a second heat sink (20) being enclosed by the first heat sink, and a plurality of heat pipes (30) connecting the second heat sink to the first heat sink. The second heat sink includes an annular base (22) and a plurality of fins (24, 240) extending outwardly and radially from an outer sidewall of the base. The heat pipes couple the base of the second heat sink with the first heat sink, so that heat generated by the LED modules can be transferred from the first heat sink to the second heat sink via the heat pipes, thereby enhancing a heat dissipating efficiency of the LED lamp.

摘要： An LED lamp includes a heat sink (10) and a plurality of LED modules (20) mounted on a periphery of the heat sink. The heat sink defines a through hole (122) from a lateral side to an opposite lateral side thereof to define a cylindrical inner face. A plurality of fins (16) are attached to the heat sink in a manner such that the fins have spaced external portions (160) extending outwardly from the periphery of the heat sink, and opposite internal portions (162) extending inwardly from the inner face of the heat sink. The internal portions connect with each other to form a joint (164) in the through hole, thus increasing a heat dissipating area of the heat sink and reinforcing the heat sink.
