LED Symposium in Bregenz started
presentations from international experts. Almost 60 manufacturers and other exhibiting companies including market leaders such as Osram, Avago Technologies, e:lumix, Tridonic, Philips Lumileds or Cree present their latest products that are all about the LED-technology.
The usage of LEDs for illumination purposes is a very complex issue, explained symposium director Siegfried Luger. “Today you all witness the origin of a new technology fair, similar to the ’embedded world’ in Nuremberg a couple of years ago,” Luger said at the press conference. According to Luger, LpS has the potential to become the leading trade fair or the most important European event that is all about the LED-technology in lighting applications.
The organizer was able to win over a number of known experts as contributors for the convention. Contributors came from central Europe as well as from Israel, Taiwan and the USA.
In contrast to light bulbs (or their socket-compatible substitutions) the LEDs, however, are not suitable – apart from some special exceptions – for the direct connection to the 230AC grid as the LEDs require regulated current at a low DC voltage. This calls for a special electronics know-how that the classic lamp manufacturers very often do not possess in this form yet. Then again, LEDs offer new degrees of design flexibility, enabling a broad range of new applications.
Although the LED-light sources are exceptionally energy-efficient even these semiconductors emit heat to the surroundings; however, this happens in a completely different way in comparison to the so far used illuminants, thus an efficient thermo-management is an absolute must. By selectively controlling LEDs it is possible to generate light in any desired color. Having the proper device at one’s disposal the end user can even determine the color and intensity of the light at any time matching his individual requirements.
The design of LED-lamps requires proper system integration where know-how in the fields of LEDs, electronics, optics, thermo-management and manufacturing technology is demanded.
