Atmel powers this 2D-Lux smart LED disk (SLEDD)

NliteN has unveiled the 2D-Lux Smart LED Disk (SLEDD), a dimmable 60W-incandescent-replacement LED smart “bulb” with an Atmel AVR microcontroller (ATtiny85), USB interface and hardware-expansion pins. Currently on IndieGoGo, the Atmel-powered SLEDD allows backers to easily adjust the 2D-Lux by running various light-bulb control apps, including smartphone control.

“The low power sleep modes found in Atmel’s AVR, as well as its wide voltage operating range, has allowed NliteN to eliminate expensive AC to DC power supplies, as well as eliminating the need for large electrolytic capacitors which are a huge reliability and lifetime concern in Solid State Lighting today,” explained Andreas Eieland, Atmel’s Sr. Product Marketing Manager of Standard Microcontrollers. “The AVR’s high processing throughput allows inexpensive, direct, USB interfacing to the AVR, facilitating the ability of an owner to download apps by simply attaching a PC’s USB cable to the integrated connector on the bulb.”

In addition, Atmel’s low noise, high precision, on-chip analog to digital converters enabled NliteN designers to measure system temperatures to prevent system overheating in enclosed fixtures – as well as monitor AC power waveforms and implement a planned low-cost powerline receiver communications capability similar to the BSR X10.

It should also be noted that users can add shields, or plug-in circuit board modules to SLEDD, facilitating additional hardware functions via microphones (clap on, clap off, clap dim, loudness sensitive brightness, etc), motion sensors, Zigbee, Bluetooth, WiFi, Linux web appliance and battery-backed-up clock-calendars.
