The invention relates to a lamp comprising an LED (2) and a cooling body (4) for cooling the LED (2). The LED (2) is arranged in a pivotal manner in relation to the cooling body (4). The lamp further comprises a cooling liquid (8), for example water, for the heat transfer from the LED (2) to the cooling body (4). A receiving chamber (10) that is delimited by the cooling body (4), a membrane (6) and a carrier element (14) for a circuit board (12) of the LED (2) can be provided for the cooling liquid (8). For arresting the LED (2) in a certain position in relation to the cooling body (4), arresting means, for example detent elements in the form of recesses (50) and engaging elements (51), can be provided. As the LED (2) can be pivoted in relation to the cooling body (4), a separate optical element for changing the direction of the light emission is not necessary. Furthermore, the cooling body (4) does not have to be arranged in a pivotal manner, so that a comparatively small size of the luminaire can be implemented. |
