Maxim to Demo a LED Ballast with Inside Teridian Based Real-Time Power Efficiency Measurement at LIGHTFAIR

At LIGHTFAIR 2011l in Philadelphia, Teridian Semiconductor, a subsidiary of Maxim Integrated Products, will demonstrate both AC- and DC-power measurement suitable for high-power LED-lighting ballasts. Using the Teridian/Maxim 78M6613 energy-measurement system-on-chip (SoC), the demo, located at Maxim’s booth #3351, will validate the interoperability of various components to create a ballast capable of measuring its own power efficiency.

• At LIGHTFAIR(R) International, Teridian/Maxim will demonstrate AC- and DC-power measurement suitable for a high-power LED-lighting ballast.
• Using the 78M6613, the demo will validate the interoperability of various components to create a ballast capable of measuring its own power efficiency.
• Inside the lighting ballast of the luminaire, the 78M6613 replaces a microcontroller unit that receives DALI commands and controls dimming, and adds functionality for accurate power-consumption management.
• The lighting ballast featured in the demo is targeted for various applications, including warehouse, architectural, garage, parking lot, street and highway lighting.

Targeted for applications such as warehouse, architectural, garage, parking lot, street, and highway lighting, the demo will feature a lighting ballast that has both Digital Addressable Lighting Interface (DALI) and Zigbee(R) controls. Using the 78M6613 enables high-measurement accuracy (±3 percent) without needing to calibrate the ballast. It also provides a simple, configurable interface that remains independent of regression testing done on the communications firmware to resolve network interoperability and user application issues.

“Monitoring and verification is essential feedback for any energy-management system, but energy measurement is not a core competency for most lighting manufacturers,” said Jay Cormier, Maxim Integrated Products Director, Teridian/Maxim Business Management, Energy Measurement & Communications. “As our demonstration will show, a remotely controlled LED-lighting ballast can be easily upgraded to include real-time energy-efficiency measurement without increasing the number of electronic components or incurring the manufacturing costs of calibration.”

Inside the lighting ballast of the luminaire, the 78M6613 replaces a microcontroller unit that receives DALI commands and controls dimming, and adds functionality for accurate power-consumption management. The device also provides digital information to assist with diagnostics.

The 78M6613 is the industry’s first SoC energy-measurement solution for AC and DC power that enables the capture and reporting of real-time energy data. This provides the ability to quantify where energy is needed, used and stranded. With an embedded analog front-end and compute engine, small footprint and embedded firmware, the 78M6613 features best-in-class accuracy of ±0.5 percent over a 2000:1 dynamic range. The SoC also provides powerful tools for self-calibration to help facilitate rapid design time and optimal manufacturing costs. It includes the full range of AC-power diagnostics—including power, power factor, voltage current, voltage sag and dip—and eliminates the need for external components.
