Abstract
A light-emitting diode (LED) includes a heat sink (10) having a cross section along an axial direction thereof being U-shaped. The heat sink includes a substrate (102) and a sidewall (11) extending from an outer periphery of the substrate. A circuit board (40) is received in the heat sink and arranged on the substrate. At least one LED (30) is arranged on and electrically connected to the circuit board and thermally connected with the substrate of the heat sink. A plurality of fins (100) extend outwardly from an outer surface (110) of the sidewall of the heat sink. Each fin has a plurality of branches (100a, 100b) being connected together at the outer surface of the sidewall and being spaced from each other at outer-peripheries thereof.
