Abstract

A device and method are provided for controlling the temperature, in particular for cooling, of an LED lamp or LED modules of an LED lamp, e.g., for curing a light-cured pipe. The device includes: a fluid supply line and multiple heat exchangers connected to the supply line; multiple LEDs coupled to each heat exchanger with respect to heat transfer; and a fluid return line. The fluid supply and return lines are connected to each other in a fluid-tight manner by various combinations of L-pieces and T-pieces in or at the ends of the fluid supply and the return lines, so that the fluid flows from the LEDs in a spatially separated way and the fluid supply and return lines have at least two parallel fluid connections to each other, the heat exchangers being arranged in the fluid connections or constituting the fluid connections.
