MENTOR Square Light Guides – Differentiate your product!

Square Light Guides / Light Pipes are an innovative product range from MENTOR.  I like them because they not only look great but allow you to visibly differentiate your product designs from the more mundane. It is worth noting that whilst the 10-column array versions have multiple tiny light elements closely spaced together, MENTOR’s clever integrated diaphragm prevents light bleed even when different colours are used adjacent.

Multi-element arrays added to MENTOR’s rear-mounted front panel Light Guides / Light Pipes

MENTOR have added multiple array versions to their range, and all of the engineers I have shown rear-mounted samples to were very impressed.  OK, they are not going to change the world but they are a clever concept that is highly practical and do enhance optical quality.  However if you need IP68-rating, look elsewhere – by definition rear-mounted versions cannot deliver this (yet!).

MENTOR from Multitron. Rear-mounted light guides.

Cleverly-designed range of rear-mounted front-panel light guides.

Conventional front-mounted light guides will by definition always have heads slightly larger than the enclosure’s hole, which results in not all of the head being directly illuminated by the LED. The advantage of mounting from the rear of the panel is that all of the light guide head is directly illuminated and this produces a markedly superior lighting effect.

MENTOR’s square and round tactile / dome switches

Square switch cap, round hole!

During my recent factory visit I explained to MENTOR that Multitron’s UK Design Engineers were loving the flexibility and cost-effectiveness of MENTOR’s switch cap solutions but many were asking for round / circular versions rather than square.  I quite reasonably berated MENTOR for their short-sightedness in not supplying these.

MENTOR R&D. Corona and rim - contour lighting light guides.

MENTOR R&D Development – Corona & Contour / Rim Lighting light guides. An opportunity to work alongside MENTOR.

MENTOR’s R&D guys always complain that they are too busy to take-on any more customer-specific projects (but they always do)!  I don’t reckon they can be that busy because in their “spare time” they have come up with two very interesting light guide developments, namely corona and contour light guides.  If I told you more I would have to shoot you but I am allowed to show you these images.
