Cypress Semi EZ-Color HBLED Controller Family Enables Fast Design Of WAC Lighting’s New Display and Accent LED System

September 28, 2009 by Jeff Shepard

Cypress Semiconductor Corp. announced that WAC Lighting, a manufacturer and designer of track, recessed, undercabinet, decorative and monorail lighting, has selected Cypress’s EZ-Color™ high-brightness LED (HBLED) controllers to control the LEDs in its new color-changing tape light system. Based on Cypress’s flexible PSoC® programmable system-on-chip, the EZ-Color solution enabled WAC Lighting designers to quickly introduce the energy-efficient INVISILED™ PALETTE system to the display and accent lighting markets.

INVISILED PALETTE uses the CY8CLED02 EZ-Color controller to manage red, green and blue diodes to create unique color-changing capabilities. With EZ-Color’s patent-pending PrISM™ (Precise Illumination Signal Modulation) technology, the color changes are programmed in a constant, smooth transition with adjustable speed among the three colored diodes and can be stopped at any point for a custom color effect. The PrISM modulation technology also significantly reduces low-frequency flicker and radiated electro-magnetic interference (EMI) – common problems in LED lighting designs.

"The Cypress EZ-Color solution provided us the flexibility and ease-of-use of the PSOC architecture while integrating the color mixing algorithms we required for our INVISILED PALETTE system," said Shelley Wang, President of WAC Lighting. "The smooth color-changing effects of the EZ-Color solution help PALETTE stand out from the competition."

"WAC Lighting’s innovative LED lighting systems are a great showcase for Cypress’s EZ-Color family," said Curtis Davis, Vice President of Cypress’s PowerPSoC Division. "The PALETTE system shows how our EZ-Color solution streamlines design with HBLEDs while also bringing smart lighting effects to the market."
