PHOENIX -- If you missed Avnet Electronics Marketing Americas demonstrations at this year's LIGHTFAIR International show - you're in luck. Avnet, Inc. (NYSE: AVT) will bring the latest high-brightness light emitting diode (HBLED) technology to you!
This year, Avnet demonstrated the flexibility of a novel HBLED luminaire control concept, called MONALISASM (Modular Networked Avnet LightSpeed Architecture). Designed by Avnet, this system uses wireless touch-control technology to unleash a full-spectrum of colors, warm-cool color temperature settings and dimming levels of HBLED sconces, spotlights and pendants.
MONALISA's hand-held remote uses Atmel® QTouch® technology implemented on an ATtiny88 microcontroller, along with an AT86RF230 low-power 2.4 GHz transceiver and ATxmega1281 low-power microcontroller. Each of the luminaires is powered by a National Semiconductor LM5021 AC-DC current mode PWM controller, LM3409 constant current LED driver, Atmel AT86RF230 and ATxmega1281. The products operate together to provide a universal input, constant current output driver that is able to supply up to 100W of managed power to red, blue, green, warm white and cool white HBLEDs.
Avnet and ST-Microelectronics also demonstrated the STEVAL-ILL022V1 solar-powered HBLED streetlight reference design. The system incorporates Maximum Power Point Tracking (MPPT), daylight sensing, smart battery charging, constant-current output drive and full protection/supervision functions. This demonstration is one of the videos on Avnet's LIGHTFAIR webpage. You'll also see a demonstration of a transparent down light built by Avnet that uses fanless-cooling and an array of photonic lattice HBLEDs.
"To truly deliver on solid state lighting, it's important to consider the entire system - ranging from user interface, control, and thermal management to form factor, environmental interaction, luminous output and energy efficiency," said Cary Eskow, director of technology for Avnet Electronics Marketing, Americas. "Avnet's technical capabilities and product offerings meet the diverse and demanding needs of today's solid state lighting designers - helping to get their innovative products to market faster."
