The LED has established itself as the light source of the future. Innovative heat dissipation concepts for cooling LED’s are in more demand than ever before to maximise LED efficiency and long service life. To satisfy this demand, Fischer has expanded its comprehensive LED cooling product range with the addition of three new active solutions. 

The product series LA LED 40x30, LA LED 50x20 and LA LED 50x45 consists of a pin fin heat sink and a round fan with a motor that has been specifically designed for active LED cooling. The fan motor has a double slide bearing and is designed for the particular requirements of LED applications in terms of noise and service life. It is screwed to the top of the pin using internally threaded distance sleeves that are provided for this purpose. With their special arrangement and high number of pins, the compact pin fin heat sinks are designed for optimal air throughput.

Thanks to the properties of their materials, their geometry and structure, these pin fin heat sinks are extremely efficient coolers for electronic components in free convection, but particularly also in forced convection. The aluminium alloy used (Al99,5) has very good heat conductivity. In addition, the manufacturing process serves to create a homogenous material arrangement and microstructure that follows the direction of the heat flow - all of which ensures fast and even heat distribution in the heat sink base and fins.

The LEDs can be fastened to the pin heat sink with thermally conductive adhesive, double-sided thermally conductive foil, or screws. Mechanical treatments, custom designs and surface finishes can also be provided for your specific application.
