Strongsville, Ohio By using the latest advances in high-power LED technology, Lumitex has developed a new line of modular light engines that significantly increases brightness. The LED light engines combine one or more high-bright LEDs such as the Luxeon III Star or Luxeon V with a Lumitex woven or UniGlo fiber optic panel, resulting in increased panel brightness by as much as 20 to 50 times greater than other solutions, says the company.
Created for designers who want to spread light from a single light source over a wide, flat area, the new LED light engines use a special collimating lens that captures, then focuses the light from the LEDs to the fiber optic panel. Encased in an aluminum housing that acts as a heat sink, the assembly provides significantly increased panel brightness by driving these high-power LEDs at a higher current through more efficient heat management, said the company.
Although brightness will vary according to application and the number of LEDs used, typical brightness achieved with the new light engine is 100 Ft-L or more for a 3-in. x 5-in. fiber-optic panel illuminated by a single high-brightness LED, said the company. In addition, use of LEDs allows control over what color the light source produces, which eliminates the color shift that can be a problem with incandescents, and unlike systems using CCFL light sources, it doesn't require warm-up and aren't sensitive to shock and vibration, added the company.
The light engines can be used as an alternative to halogens, incandescents, light arrays and CCFLs for a variety of applications including touch screens, MRI illumination, LCD backlighting, and machine vision such as CCD cameras. It can also be used in a range of membrane switch applications, and a wide variety of specialty applications such as high-end salon and spa equipment.
However, the LED light sources cost more than traditional LEDs, thus, will not be a solution for every application. It will primarily be used in applications that call for the performance of ultra-bright LEDs as a key product differentiator.
Pricing for a light engine with a single Luxeon III Star light source and 3-in. x 5-in. panel is approximately $10 to $50 in OEM quantities. Pricing varies with application and the number of light sources and light engines used.
