Cypress Semiconductor Corp. (NYSE:CY) announced a free online seminar that reviews communication interfaces for intelligent lighting networks and presents tools to simplify the design process. The 60-minute webinar entitled “Communication Interfaces for Intelligent Lighting Networks” will be presented in conjunction with Electronic Engineering Times on Wednesday, June 11 at 9:00 a.m. PDT.
New designs for intelligent lighting networks must work well, be robust and reliable, and meet tight time schedules and budgets. The webinar will present the different communication interfaces and control solutions now available, ranging from the commonly used DALI and DMX512 protocols to new wireless approaches. The presenters will explain common difficulties in setting up and designing intelligent lighting networks, and will describe modules that simplify and speed up system design. Interested parties can get more information and register at seminar2.techonline.com/registration/distrib.cgi?s=1266&d=323.
“This webinar will help engineers to select the best interface for their application, and to avoid common pitfalls that stall designs,” said Gopal Garg, managing director of the Lighting Solutions Business Unit for Cypress. “Cypress is committed to helping designers implement simple, cost-effective and impactful intelligent LED lighting systems.”
One of the modules presented will be Cypress’s EZ-Color solution that combines LED controllers with PSoC Express[tm], the industry’s first visual embedded design tool, to deliver complete designs for growing applications such as general illumination, architectural lighting, general signage, entertainment lighting and more. The solution enables designers to simply select an LED part number, choose either temperature or optical feedback, and choose a color, including white.
About the EZ-Color Solution
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 Express, 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 the EZ-Color Controller. This can save anywhere from weeks to months of design time for a complex design.
EZ-Color LED controllers can support up to 16 LED strings, compared to four or five strings for competitive devices. The additional strings can mean a savings of dozens or even hundreds of controllers in very large designs, cutting design complexity, power consumption and board space. The EZ-Color LED controllers are powered by Cypress patent pending PrISM[tm] (Precise Illumination Signal Modulation) technology. The PrISM modulation technology significantly 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.
The EZ-Color family is supported by the CY3261A-RGB Evaluation Kit. The evaluation kit showcases EZ-Color’s flexibility and ease of use for high-brightness LED color mixing applications and employs temperature compensation for consistent color. Included with the evaluation kit is an interactive graphical interface enabling quick color mixing via a CIE diagram or by directly controlling each LED. The kit is available on the Cypress Online Store for US$149.
