Which technology can be reused in intelligent lighting? Maybe it's it...

There are many advantages of intelligent lighting: saving energy and making our homes, workplaces, hospitals and other places more comfortable. But in fact, intelligent lighting applications are still relatively uncommon, partly due to the commonly used wireless technology.
If intelligent lighting is to be convenient and intuitive, wireless control must be carried out by mobile devices such as smart phones, tablet computers or wearable devices. The problem is that wireless technologies that have been tested in intelligent lighting (including Wi-Fi and ZigBee) are not perfectly matched with intelligent lighting.
Why ZigBee and Wi-Fi are not so suitable for intelligent lighting
First of all, ZigBee is not found in most mobile phones or tablet computers, which means you need to add a cryptographic dog or gateway between control devices and lighting. In addition to increase the cost of the whole system, a single gateway brings additional risk: once the device strikes, you may have no choice.

Figure 1. the technology commonly used to create an intelligent lighting system means that the network can not be controlled directly from most mobile devices.
As for Wi-Fi, although it can be found in most mobile devices, it can only connect the device to the Wi-Fi router. From there, you need another form of connection (such as ZigBee) to communicate with your light. In the same way, this means at least one fault risk.
Another disadvantage of Wi-Fi and ZigBee is that it is easily disturbed.
Low power Bluetooth can solve the problem
Low power Bluetooth is one of the latest innovations in the Internet of things. Its first selling point is that it can be found in almost all smart phones and tablet computers manufactured in recent years. At this point, it has an advantage in low power wireless communication technology.
As a result, you can use most of the existing devices to directly set and control the BLE intelligent lighting system (see Figure 2). This makes the deployment and operation of the BLE control system simpler and more cost-effective. In addition, you do not need the gateway or encrypted dog required by the ZigBee or Wi-Fi control systems, which means that you can eliminate these single point of trouble. BLE is also less likely to be disturbed because it uses frequency hopping spread spectrum (FHSS) modulation.

Figure 2. most smartphones and tablets are built in BLE, which means that the BLE intelligent lighting network can be directly controlled.

Figure 3 illustrates why the BLE "mesh" network is usually more reliable than ZigBee or Wi-Fi.

Figure 3. BLE mesh network has no single point of failure.

Mesh network

The new generation of wireless lighting control systems enable each node to communicate with each other to transmit or share messages and to achieve a consistent state throughout the network. This means that you can create a Mesh network that allows network nodes to go online and downline at any time to catch up to the latest system status information from other nodes.

For end-users, it provides a self-organizing and self repairing network, and it can be controlled from one point, because all intelligence is stored in every node. The user only needs the Internet connection to enable the firmware update or store the data to the cloud.

Intelligent lighting and beacon

BLE control supports intelligent lighting that can not be realized by Wi-Fi or ZigBee. Beacon technology is a good example: it can detect when the BLE device enters or leaves the area around the beacon. When the beacon transmitter is installed in the luminaire, it can create intelligent proximity illumination. For example, when someone enters the room, it automatically activates preset scenes, or triggers lighting when people pass through buildings.

Imagine that there is a store or museum equipped with beacons. When you enter it, you will automatically trigger the application on the museum or store on your phone, showing the information about the exhibition or merchandise. Is that great?

Next step: Smarter intelligent lighting

The next generation lighting control system allows you to collect data from the sensors in the lighting and send it to the cloud for analysis (see Figure 4). The results obtained from these data can be used to enable intelligent lighting to be intelligently regulated by factors such as ambient light, humidity, or CO2 content. It can also be used to count the numbers, record events, or provide marketing information at the right time, and help managers.

Figure 4. intelligent lighting control system can collect sensor data and send it to the cloud for analysis. Insight into the results can support intelligent lighting control and simplified operation.

Although the future is still in the future, it is worth looking forward to.
