High-reliability flexible LED strips for industrial and signage applications

New Products |
Unlike many LED lighting strips which are designed for relatively short-term, decorative use, OMC's Flexistrip product uses closely spaced, ultra high brightness LEDs and incorporate a number of unique features that ensure long-lasting, bright and even illumination.

Strips can be cut to length with scissors and fixed in place using the pre-fitted, high bonding adhesive foam tape backing. Ideal for a wide range of industrial and sign-making applications, Flexistrip LED strips benefit from in-built electrostatic and reverse-polarity protection and an extra-thick copper substrate for enhanced reliability and longevity. Positive and negative connections to a low voltage supply power the strips, and a simple two-wire link can be used to carry power from one strip to the next. The very high number of LEDs per metre eliminates many of the most commonly seen problems with LED illumination – such as light and dark patches or ‘spottiness’ in a beam – and means stunningly bright, consistent illumination in a vast range of applications.

For optimal reliability, the LEDs used in the construction of the Flexistrip range are bin-sorted very tightly, with voltage bins as narrow as +/- 0.05V. This crucial step, skipped by many strip designs on the market, results in all the LEDs on the Flexistrip being driven at the same drive current. Without it, some chains will draw more current than others and can be overdriven, causing groups of LEDs to fail over time. In addition, the bin sorting ensures consistency of brightness along the strip.Two types of Flexistrip are available, front-firing and side-firing. The front-firing Flexistrip features 90 ultrabright LEDs per metre, is 10.5mm wide and offers a beam angle of 120 degrees and the light is emitted from the flat face of the strip. Total strip height is only 3.6mm and can be reduced further to 2.1mm if required by omitting the VHB foam tape backing. The side-firing Flexistrip has 78 ultrabright LEDs per metre, is 12.5mm wide and has a unique elliptical beam profile. This 30 x 60 degree beam, emitted from the side of the strip face, enhances intensity transverse to the strip while achieving fast beam mixing between adjacent LEDs. Total strip height is 7.0mm, or only 5.5mm without the VHB tape.

Both strip types are available in both 12V and 24V versions and in a wide range of colours, and the front-firing strip is also available in RGB.
