Smart lighting controls guide for electrical installers A guide for electrical installers Architectures In a world where people manage their social lives, entertainment and banking from their mobile devices, they expect to do the same with their lights. Casambi makes this possible thanks to cuttingedge technology behind the scenes. But just because the equipment is high-tech, this doesn’t mean it has to be complicated to install. Wi-Fi Wi-Fi / ZigBee Single Point of Failure BLE What is smart lighting? Smart lighting isn’t just about dimming or turning on and off in response to sensors and timers. Smart lighting is connected and intelligent, so that it can change in brightness or colour in response to all kinds of stimuli. This can be used to save energy, to enable dynamic light displays, and deliver ‘human-centric lighting’ that promotes well-being. By harnessing the Internet of Things, smart lights can be controlled from mobile devices or programmed to respond to data from other devices and online services – such as the weather, the location of your car as it pulls up outside the front door, or the TV being switched on. With smart lighting the possibilities are endless. KEY Wi-Fi Wi-Fi Router Wi-Fi Receiver Wi-Fi / ZigBee Wi-Fi Router ZigBee Gateway ZigBee Transceivers There are numerous so-called ‘smart’ lighting systems available – and some are smarter than others. In the past they have mostly been based on Wi-Fi, ZigBee or both: a mobile device uses Wi-Fi to talk to a gateway (such as a router) and the gateway uses ZigBee to talk to the lights. Neither of these two protocols is ideally suited to controlling lighting: they’re prone to interference, require a strong network signal at all times throughout the whole area where lighting is in operation (which is difficult to achieve and can compromise data security), and their reliance on a gateway introduces a single point of failure, making the whole system fragile. Casambi’s revolutionary system is based on Bluetooth Low Energy, the only low-power radio communication technology that’s built into every modern smartphone, smart watch, laptop and tablet. It provides robust, professional-level smart lighting control from almost any mobile device – and installation couldn’t be simpler. www.casambi.com 2 BLE Bluetooth Transceivers Single Point of Failure Smart lighting - how does it work? Leading lighting manufacturers have integrated Casambi’s Bluetooth module into their luminaires, drivers and control modules to make them compatible with the Casambi system. The module can also be retrofitted into standard light switches. To control the lights, users simply download the Casambi app to their Android or iOS device for free, or use compatible wall-mounted or wireless switches. Fittings equipped with the Casambi Bluetooth module can communicate directly with mobile devices, and with each other. They form a self-organising and self-healing mesh network where each luminaire can relay information to and from others, so if any individual luminaire fails, or is removed or reconfigured, the lighting controls keep working. www.casambi.com 3
