LED Light Guides emit light from top and bottom surface.

LED Light Guides emit light from top and bottom surface.

Global Lighting Technologies, Inc.    Brecksville, OH 44141
Mar 05, 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.

LED-Based LCD Light Guides enable sunlight readability.

Elma Electronic Inc    Fremont, CA 94538
Aug 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.

Light Guides withstand high temperatures.

Elma Electronic Inc    Fremont, CA 94538
Jun 21, 2007 Available in single/dual LED version and vertical and horizontal orientations, light guides withstand 260C for 40 sec, or 200C 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.

LED Tubes suit instrumentation and diagnostic equipment.

Elma Electronic Inc    Fremont, CA 94538
Mar 20, 2007 Available in lengths of 100 and 300 mm and diameters of 5, 6, 8, and 10 mm, M-Tube LED Light Systems feature modular design that allows them to be bent or angled. Units include single elements, clamping sleeve, LED housing, and second housing for double-ended light irradiation. Flexible color imprinting allows various widths and patterns so that large-area lighting or narrow spotlight is possible. Light guide bar remains cool even when brightly lit.

Light Guides are RoHS compliant.

Elma Electronic Inc    Fremont, CA 94538
Jul 31, 2006 Featuring integrated LEDs, M-Pipe light guides can withstand 260C for 40 sec, or 200C for 180 sec. Removed from direct contact with front panel, LED devices provice 7-12 kV isolation. M-pipes come with or without additional solder tags or fixing pins; with single or dual LED versions in 2 diameters and shapes; with or without adjacent-light radiating covers; and in vertical and horizontal orientations. Devices are compatible with all standard automatic insertion equipment.

Molded LED Light Guides provide backlighting solution.

Global Lighting Technologies, Inc.    Brecksville, OH 44141
Mar 29, 2006 MicroLens(TM) molded light guides can be designed in sizes from 0.24-15.4 in. diagonal to provide single LED monochrome, bi-color, or tri-color backlights. Pixel-based light extraction technology provides transition area that spreads light uniformly, extracting light at each point across panel. With packages no thicker than 0.60 mm and power consumption of 1-20 mA at 3.5 V, applications include PDA keypads, desktop monitors, and instrumentation and control displays.
