LED Light Guides emit light from top and bottom surface.

March 5, 2014

Using single Light Guide with LEDs on 1 or 2 edges, fixtures can emit light upward and downward, while varying distribution pattern from top to bottom. One such option is light guide that will produce batwing distribution in upward direction, while maintaining more direct distribution in downward direction. This would allow proper illumination of table or desk below light guide while simultaneously allowing indirect lighting of room from upward distribution. Read More

LED-Based LCD Light Guides enable sunlight readability.

October 22, 2012

Intended for sunlight-readable displays, High-Brightness Light Guides are available in variety of sizes to fit customer's requirements. Assemblies utilize mid-power LEDs mounted on metal core PCB with passive thermal management and can be seamlessly integrated into customers' end-product displays. Typical 7 in. diagonal backlight consumes less than 15 W of power and produces brightness of 50,000 cd/m² at surface of backlight. Units are suitable for automotive, avionics, marine, and POP displays. Read More

Thin Light Guides backlight touch-enabled display graphics.

September 27, 2010

Utilizing LED-based edge-lighting technology, Edge-Lit Light Guides provide bright, uniform light where needed for directional symbols, on/off buttons, company logos, rotary switches, sliders, and other graphic icons. Edge lighting technology employs side-firing LEDs and focuses light into thin light guide of 0.6 mm or less. Placed between PC board/circuit sensor and graphic overlay, light guides are compatible with variety of overlays. Read More

Light Guides have thin, 0.4 mm profile.

May 7, 2008

Designed for portable devices, mobile phones, laptop and desktop LCDs, keypads, and keyboards, Microlens(TM) Light Guides feature MicroLens(TM) light extraction technology, which reduces number of LEDs required. They provide bright, uniform light in thin form factor with no hot spots or dark areas. Light is extracted precisely where needed, such as around thru-holes for keypads, and devices can backlight LCD displays in sizes from 0.25-50 in. diagonal. Read More

LED Light Guides feature IP68 sealed design.

August 21, 2007

Available in various diameters, lengths, and colors, LED Light Guides are offered in protruding styles or versions that are mounted flush with front panel. Chamfered light coupling area allows other LEDs to emit light perpendicular to circuit board. IP68 sealing is accomplished through special shaping of light guide body accompanied with precision boring by customer. Light guide lengths are available up to 100 mm on request. Read More

Light Guides withstand high temperatures.

June 21, 2007

Available in single/dual LED version and vertical and horizontal orientations, light guides withstand 260°C for 40 sec, or 200°C for 180 sec. Offering ESD protection, light guides are far removed from direct contact to front panel. LEDs are suited for vapor phase soldering and lightpipes come with or without solder tags, fixing pins, and adjacent light radiating covers. Read More
