Abstract

The invention provides an LED lamp (1 ) including an outwardly curved reflector (2) connected to a base plate (3). The base plate (3) extends across an inner end of the reflector (2) and a printed circuit board (4) carrying an LED light source is mounted to the base plate. The reflector (2) and base plate (3) are preferably made as an integral component from heat conductive material to provide a heat sink. An additional body (6) of heat sink material is fixed to the side of the base plate (3) opposite the circuit board (4).
