The service life of LEDs directly depends on their heat dissipation concept. Drastic temperature fluctuations will considerably shorten it, and overstepping the permitted chip temperature has a direct impact on the light yield. The use of extruded aluminium heat sinks for free convection already serves as an effective LED heat dissipation concept today.
With an active LED heat dissipation concept under the article number LA LED 68, Fischer Elektronik expands its comprehensive product portfolio for weight-sensitive applications. The base is made from a thermotechnically optimised aluminium hollow-chamber profile. Zhaga-conform LED modules can be directly bolted to the front of this by way of additional threads. There is also the option of fastening various LED modules from different manufacturers, as well as their holder systems, to the pre-threaded mounting plate with the help of an adapter screwed into the base section.
A special low-noise fan motor in a round design is integrated in and fastened to the back of the base section. The motor has a double slide bearing and is designed for the special requirements of LED applications where noise and lifetimes are concerned. Mechanical processing, cover panels with ventilation slits, customised designs and surface coatings are also all available for your application.
