For Use in Specialty Lighting Applications

LATHAM, N.Y., April 5, 2006 -- LED maker Marktech Optoelectronics announces the addition of Cotco’s new WR1 series to its lineup of high-performance LEDs. The company says the new warm white WR1 series combines familiar LED benefits such as long life, small die size and rugged design with a pleasant warm color.

This series is offered in both 5 mm and surface mount package styles. Used wherever specialty lighting is needed, these versatile, general-lighting LEDs open up new applications in reading lights, mood lighting, display cabinets and car interior lighting, according to Marktech.

Cotco warm white LEDs deliver superior color rendering and color temperature previously associated only with incandescent and halogen lamps, the company said. This is achieved by changing the product’s converter mix. White light is normally produced when a blue chip is combined with a yellow converter phosphor. By adding a red converter phosphor, a warmer white tone is achieved. Cotco has perfected this phosphor mixing technique to achieve a consistent typical color temperature of 3000 K for thru-hole devices and 3200 K for SMT packages, Marktech said.

Cotco WR1 Warm White Features:

Surface mount and 5 mm packages
Available in 15?, 25?, 50?, 120? viewing angles

Pricing for the WR1 warm white LEDs from Cotco, which are only available through Marktech, starts at 58 cents in 5 K lots depending on package. In addition to their Cotco line, Marktech also offers Toshiba Tosbright LEDs and Toshiba constant current LED drivers along with a range of standard discrete LEDs, surface mounts, displays and photosensors.
