MENTOR’S coloured light guides are a novelty in the area of optoelectronics. They are available from Erntec Pty Ltd.
Designed for transfer of light to the front panel, even if the light emitter is inactive - the system will still assign a signal display to the signaller.
This is made possible by translucent, intensive colouration of the light guide. In this way the new system is able to visualise information about imaginable switching status beforehand without them occurring.
The light guide portrays the epoxy-made LED body and transfers the signal to the front panel.
The variable system is serviceable with a LED-like form of display, with a flat display panel and chamfer for improvement of the visualisation as well as for flush mounting with the front panel.
Due to their variability of length within a range of 4.5-45mm, the guides are used in many different ways.
Additional variants in the system have a chamfered light coupling area that makes it possible to use less expensive TOPLEDs and SmartLEDs, and to emit light parallel, for example, with a 90° light coupling in relation to the printed circuit board.
The light guide system for the front panel assembly has an outlet-geometry of 3mm or 5mm and allows the use with all common LEDs.
ESD resistance reaches 10kV at a length A of 4.5mm and increases by approximately 1kV per additional mm of length.
