Abstract
An LED lamp includes a heat dissipating base and a plurality of light strips. The heat dissipating base is formed by aluminum extrusion and has a length direction defined by the aluminum extrusion direction. The heat dissipating base has a main body and a plurality of heat dissipating fins. The bottom side of the main body has a flat connecting surface. The heat dissipating fins extend outward from the main body. Each light strip has a circuit board and at least one LED module provided on the circuit board. The circuit board of each light strip is provided on the connecting surface of the heat dissipating base. The width (W1) of the connecting surface of the heat dissipating base is greater than three times the width (W2) of each light strip, i.e., W1>3W2.
