LEDs have become the lighting medium of the future in many areas of daily life. Innovative cooling concepts to cool the LEDs are more requested and in demand than ever to be able to use the advantageous properties of the LED truly effectively and with a particularly long service life. For this purpose, the company Fischer Elektronik is expanding its product range of LED heatsinks with cellular heatsinks in a round model with individual design possibilities of the series KTE R. They are used to receive the aluminium LEDS from a full aluminium core with continuous grooves in which aluminium pates are attached for heat abduction via a pressure/adhesive bond. The core diameter to the LED receiver, the plate number, thickness and geometry can also be adapted to all conventional LED modules and sizes according to customised specifications. Due to the design flexibility, there is also the possibility to integrate complete LED systems including reflectors and the corresponding LED hold but also by using fan motors for active cooling. Different surfaces, mechanical processing as well as receptacle cores for heat spreading from copper can also be used.
