Intelligent lighting solutions for high bright LEDs to achieve efficiency

Cypress Semiconductor announced its intelligent lighting solutions to support the Power LED series from Nichia Corporation. Using Cypress's PSoC Designer 5.0 visual design software and the CY3265N-RGB evaluation kit, designers can input the selected power device; select bin specifications through the drop-down menus; and choose a color, including white - without having to write a single line of firmware.

Cypress has integrated the Power LED series specifications and temperature characteristics into the content library of PSoC Designer 5.0 software, which supports Cypress's EZ-Color LED controllers.

LED lighting design requires a complex set of calculations with custom firmware to deliver consistent color. The two biggest problems that LED lighting engineers face are having to account for differing LED performance specifications based on manufacturing bins and the LEDs' degradation (such as output flux, wavelength etc.) over different temperatures. With PSoC Designer 5.0, designers simply select a color from a gamut presented on-screen. Pre-loaded manufacturers' bin specifications and choice of either temperature or optical feedback algorithms are automatically applied to the selected design and programmed into an EZ-Color controller.

The EZ-Color LED controllers can support up to 16 LED strings. They are powered by PrISM (Precise Illumination Signal Modulation) technology. The PrISM modulation technology reduces low-frequency flicker and radiated electro-magnetic interference (EMI)-common problems in LED lighting designs. Designers also have the flexibility to add additional functionality to the EZ-Color controllers, including battery charging, motor control, thermal feedback, programmable control gear and other features.

Cypress has introduced the CY3265N-RGB evaluation kit enabling designers to begin simplified system design with XLamp LEDs. The kit comes with a daughter card featuring Power LEDs, and includes a MiniProg, a 5v LCD display, a USB cable, a CD with PSoC Designer 5.0, Gerber files and schematics.

Availability: The kit is available on the Online Store & from authorized distributors.
