Cypress Semiconductor has introduced a complete design solution for high-brightness (HB) LED intelligent lighting systems which claims to offer unprecedented ease-of-use and performance. The new EZ-Color family of HB LED controllers is supported by PSoC Express, said to be the industry's first embedded visual design tool.
With this solution, engineers can simply input the selected LEDs, choose a colour, and the combination of the EZ-Color architecture and PSoC Express software delivers a complete design solution for growing applications such as architectural lighting, general signage, rechargeable flashlights, entertainment lighting, emergency vehicle lighting and more.
Traditionally, LED design requires a complex set of calculations to deliver consistent colour. The two biggest problems that HB LED engineers face today are having to account for differing LED performance specifications based on manufacturing bins and the LEDs' degradation (such as output flux and wavelength) over different temperatures. With PSoC Express, designers simply select a colour from a gamut presented on-screen. Pre-loaded manufacturers' bin specifications and temperature feedback algorithms are automatically applied to the selected design and programmed into the EZ-Color controller. This can save a significant amount of design time, particularly in a complex design.
EZ-Color controllers support up to 16 LED channels, compared to four or five channels for competitive devices. The additional channels can mean a saving of dozens or even hundreds of controllers in very large designs, saving on design complexity, power consumption and board space. These controllers are also powered by Cypress patent pending PrISM (precise illumination signal modulation) technology. The PrISM modulation technology significantly reduces low-frequency flicker and radiated electro-magnetic interference (EMI) - common problems with HB LED designs. Designers also have the flexibility to add additional functionality to the EZ-Color controllers, including battery charging, motor control and other features.
The EZ-Color family is supported by the CY3261A-RGB Evaluation Kit. This kit showcases the controllers' flexibility and ease of use for high-brightness LED colour mixing applications and employs temperature compensation for consistent colour. Included with the evaluation kit is an interactive graphical interface enabling quick colour mixing via a CIE diagram or by directly controlling each HB LED.
