An LED spotlight that is operable to emit light with a selected emission angle measured relative to an emission axis of the spotlight comprises: a dish shaped (parabolic) reflector and a plurality of LEDs, wherein the LEDs are configured such that in operation each emits light in a generally radial direction to the emission axis of the spotlight and wherein the light emission axis of the LEDs is configured at an angle to the emission axis of the spotlight of at least 40°. In preferred embodiments the LEDs are configured such that their emission axis is substantially orthogonal to the emission axis of the spotlight and the reflector comprises a respective parabolic light reflective surface portion associated with a respective one of the LEDs. |
