A flexible LED lighting system
data sheet
The PIN system is designed for application above all in channel letter advertising systems as a substitute for the fluorescent lamps and neon lights currently used. Application is also possible in any other lighting system in which flexibility of light source is required. It is resistant to atmospheric conditions and is suitable for any location which will not be exposed to direct contact with water.
The PIN system is distinguished by two novel solutions:
- a pin-based means of powering LED modules has eliminated soldered power cable
connections (the most common cause of failure and drops in voltage);
- the use of heat-conducting resin for sealing has allowed a greater luminosity and
considerably longer lifetime to be obtained than in systems without such sealing.
  • superb reliability
  • high resistance to atmospheric conditions
  • very high resistance to mechanical damage
  • complete freedom to set luminosity through spacing
  • opportunity to branch and extend at will
  • constant luminosity in very long systems
  • potential for unlimited, technically simple colour mixing
  • easy, low-cost and reliable assembly
The parameters given in the table are averages and may differ from the parameters of a specific unit.
PIN module dimensions: TYP1X 18 x 11 x 4 mm; TYP3X 25 x 11 x 4 mm
All modules are sealed with resin and suitable for work at temperatures from -40 to +80°C.
As an example, luminosity at the face of a letter (a light box) with use of white LEDs, 3X, LED spacing of 60 x 60 mm and white acrylic of a thickness of 3 mm is 1,000 lx.
An example of channel letter lighting
In the PIN system every module [1] is equipped with two brass pins [3]. These perform a dual role, mechanically fastening the module and cable to the surface [4] and supplying power to the module LED. The special flat SOWAR cable [2] is constructed from over 200 very fine copper wires which in contact with a pin having pierced the cable guarantee a reliable electrical connection with the module (fig. 2).
The soft PVC insulation closes the site of a puncture, making it weatherproof. Our LEDs are powered through current stabilisation microsystems sealed with heat-conducting resin, these systems ensuring a steady value for the current powering each LED - and thus also luminosity - irrespective of fluctuations in voltage. At no point in an installation is the power cable cut or soldered (fig. 1), meaning that the drops in voltage which are so significant in long structures are avoided and reliability is increased. Construction is quick and easy, requiring no special qualifications.
