LEEDARSON’s A19 Tunable White Bulb Uses Nordic’s SoC for Wireless Control over Matter
Xiamen, China– September 23rd, 2021 – LEEDARSON reveals its newly A19 lighting bulb, a tunable smart LED bulb which becomes its first smart connected home product for wireless control over open source Matter protocol, uncovering it’s pledges for bridging a wiser smart home ecosystem with Matter-connected systems in the future. This lighting bulb is developed upon Nordic Bluetooth Low Energy (Bluetooth LE) advanced multiprotocol System-on-Chip (SoC) for core processing power.
The smart LED bulb is designed to replace a conventional bulb, enabling users to wirelessly control indoor lighting in a smart home or commercial building using any compatible connected device, or using voice control via smart speakers such as Amazon’s Alexa, Google’s Assistant, or Apple’s Siri. A19 Tunable White Bulb comes in a 108 by 60mm form factor, is dimmable from 3 percent to 100 percent, tunable from warm white (2700K) to cool white (6500K), features present static and dynamic scenes for different light experiences (for example, wake-up/sunset), and provides a lifespan of approximately 25,000 hours.
LEEDARSON’s A19 Tunable White Bulb solution runs over Matter – an open-source application protocol built on top of the mature Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), as well as the mature Internet Protocol (IPv6) and other lower-layer protocols including Bluetooth LE and Thread. By using the Bluetooth LE/Thread connectivity provided by Nordic SoC, the A19 smart LED bulb allows lighting control from third party solutions, enabling interoperable communication between smart home devices, mobile app, and Cloud services. “We selected Nordic’s nRF52840 SoC for our A19 Tunable White Bulb due to the chip’s powerful and reliable performance, as well as its support for the Matter protocol which enables seamless interoperability with third party devices, apps, and smart home ecosystems,” says Kellen Yang, Global VP of Sales & Marketing from LEEDARSON. “Nordic’s commitment to Matter also greatly supports our research and development.”
LEEDARSON is a board member of the Connectivity Standards Alliance (CSA), formerly known as the Zigbee Alliance – the organization behind the Matter initiative. Nordic Semiconductor is a member of the Connectivity Standards Alliance Member Group China (CMGC) – a branch of CSA designed to promote and achieve smart-home device interoperability in China.
