Smart LED bulbs with Bluetooth Smart-based mesh offer simple consumer solution for customization and control of up to 50 domestic lights
Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that ilumi Solutions has selected the nRF51822 System-on-Chip (SoC) for its second generation of LED Smartbulbs. The new A19 and BR30 Smartbulbs employ Nordic’s technology to provide Bluetooth? Smart connectivity to both iOS and Android-compatible Bluetooth Smart Ready devices.
ilumi, based out of Dallas, Texas, is already well established within the smart lighting and Internet of Things (IoT) industry. The company’s latest release, using the Nordic nRF51822 SoC, launched recently on crowdfunding website Kickstarter, and surpassed its funding goal in just 24 hours.
The A19 is an 850+ lumen light (60W equivalent) that replaces standard form factor light bulbs, while the BR30 is an overhead or floodlight replacement producing 1150+ lumens (85W equivalent). Both Smartbulbs are equipped with Hyperlux? LED technology providing a palette of over a million colors from any shade of bright and quality white light to vibrant saturated colors. Using up to 85 percent less energy than a standard incandescent light bulb, the Smartbulbs last up to 20 years in standard operation.
The Smartbulbs can be wirelessly networked with up to 50 other Smartbulbs via ilumi’s robust Bluetooth Smart-based mesh. Unlike a standard broadcast mesh, ilumi’s mesh offers both broadcast and direct connection capability that allows for more flexible customer use, along with an output power up to 15dBm, providing more than 50m of bulb-to-bulb over-the-air range, thanks in part to Nordic’s nRF51822 SoC’s sensitivity which helps to extend connectivity.
“With ilumi’s Bluetooth Smart-based mesh users can outfit a whole house and achieve a full lighting control system with just a mobile app on their smartphone. The beauty is that it’s a simple set-up and robust control without the user having to deal with a bridge, router Wi-Fi network, or any complex installation,” says Corey Egan, ilumi Co-Founder and CEO.
In addition to app control and color tunability, the new ilumi Smartbulbs’ functionality helps to guide a user towards better lighting. For example, throughout setup and use, ilumi provides suggested light settings for a particular room or space. Users can also set schedules and different lighting experiences based on their preferences and time of day. For example, “sunrise” helps users wake in the morning, while torch mode turns on lighting as a person enters a room, and off again when they leave. Other modes implement “circadian” or wellness lighting to help promote the body’s natural rhythm.
Nordic’s nRF51822 is a powerful and flexible multiprotocol SoC ideally suited for Bluetooth Smart and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM? Cortex? M0 CPU with 256kB/128kB flash and 32kB/16kB RAM. The embedded 2.4GHz transceiver is fully compliant with Bluetooth v4.2, the latest Bluetooth Smart specification. The SoC’s 2.4GHz radio offers 93dBm sensitivity in Bluetooth Smart mode.
“There were two features in particular that attracted us to Nordic’s SoC,” says Swapnil Bora, ilumi Co-Founder. “Firstly we needed to implement simultaneous central/peripheral connections for our technology and at the time Nordic was the first to offer this with its S130 Bluetooth Smart software stack which is offered with the nRF51822. Secondly the SoC’s generous RAM and Flash allocation allows us to make our Bluetooth Smart-based mesh more robust and reliable.”
“The lighting industry is undergoing a revolution with the introduction of efficient and long-lasting LEDs,” says Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. “Unlike traditional lighting, this new type of illumination lends itself to color tuning, and ilumi’s Nordic-powered wireless networking and associated app are among the first to enable consumers to match lighting to their mood from their smartphone or tablet.”
