Abstract

In embodiments, the invention provides a lamp comprising: a module (10) fitted in a housing (11) of the lamp and adapted to control at least one light-emitting diode (9), LED, of the lamp; a first heat sink (1) adapted for dissipating heat generated by the module (10) when the lamp is in operation; and a second heat sink (3) adapted for dissipating heat generated by the LED when the lamp is in operation, wherein the second heat sink is different from the first heat sink.
