ZigBee for intelligent lighting

ZigBee is a low-speed, low-cost wireless communication technology that is very inexpensive compared to high-speed wireless standards such as Wi-Fi and UWB that are suitable for wireless local area networks and multimedia applications. This article mainly discusses the software and hardware design of the wireless intelligent lighting system based on ZigBee technology.

With the progress of society, energy saving and environmental protection have become the general trend. In the field of lighting, the use of new energy-saving light sources, energy-saving appliances and high-efficiency lamps to achieve the purpose of saving electric energy has been widely accepted by people. But how to achieve the purpose of saving energy through energy-saving lighting design has just been paid attention to by people. The wired-based lighting control system has disadvantages such as troublesome wiring, rewiring of equipment to be added or removed, poor system scalability, high system installation and maintenance costs, and poor mobility. Therefore, wireless communication technology is an ideal choice for realizing an intelligent lighting system. In recent years, short-range wireless communication technology has developed rapidly. The mainstream technologies include infrared technology, Bluetooth (Blue-tooth), Wi-Fi, UWB (Ultra-Wideband) and ZigBee technology. They all have their own standards, characteristics and corresponding application fields, and there are also proprietary wireless technologies such as Z-Wave and MiWi . The requirements of the intelligent lighting system itself and the characteristics of ZigBee technology determine that ZigBee is the best solution to realize the wireless intelligent lighting system.

The controller of the wireless intelligent lighting system and the lighting node only need to transmit the switching signal and dimming signal, and the data transmission frequency is not high, and the maximum transmission rate of ZigBee can reach 250 kb/s, which is very important for realizing wireless lighting. It is enough for the intelligent lighting system; each light node of the wireless intelligent lighting system often needs to form a star network, a cluster network or a mesh network, and the number of nodes is between tens and thousands. ZigBee is suitable for the above topological structures. It has made good support, and the maximum number of nodes in the network can reach 65 535, which well meets the requirements of the wireless intelligent lighting system for network structure and capacity, which cannot be met by Bluetooth and infrared technology; different manufacturers produce Interoperability is required between various nodes of the wireless intelligent lighting system. ZigBee is an open global standard. All major ZigBee solution providers in the world have passed the compatibility test of ZigBee Alliance, and ZigBee Allianee has specially formulated corresponding standards for lighting systems . Profile, so the light nodes developed by different manufacturers based on ZigBee technology can interoperate and replace each other, so as to protect the interests and cost investment of manufacturers and users, which is impossible for proprietary wireless technologies such as Z-Wave and MiWi Satisfied; intelligent lighting system, such as smart home, requires communication between all rooms and floors, which requires the system to have the function of signal transmission through the wall and network function, ZigBee works in the ISM frequency band of 2.4 GHz, and the maximum communication between nodes The distance can reach 100 m, the signal has a certain ability to pass through walls, and ZigBee supports routing nodes. As long as the layout is reasonable, it can ensure that there is no wireless communication blind area in the building, which cannot be provided by infrared technology; ZigBee has a faster response Features, a data transmission process between two nodes can be completed within 5ms, which meets the real-time requirements of the lighting system; the lighting system is very sensitive to cost, which will determine whether it can be practical and industrialized, ZigBee It is a low-speed, low-cost wireless communication technology. Compared with high-speed wireless standards such as Wi-Fi and UWB, which are suitable for wireless local area networks and multimedia applications, the cost is very low.

The "Magic Wand" smart lamps of HOMA are embedded with motion sensor and daylight sensor, using a "Magic Wand" remote control, users can set grouping and parameters very fast and convenient. By adopting the standard ZigBee technology, "Magic Wand" has the inborn advantages like long transmission distance, multiple channels and mesh network.

Users can set grouping with one button on remote control and quickly change the lamp to another group. The lamp quantity in one group is up to 30 units, and the maximum number of groups is 500. The gateway and complex settings in APP are not necessary anymore.

Users can set the sensor parameters of one group or individual lamp with one button, and change lamp brightness. In one group, the motion sensors work together to control these grouped lamps, and the daylight sensors control the individual lamps on/off according to the ambient brightness.

The magic wand smart lamps' installation is exactly the same as that of common lamps, and after replacing, users add the lamp in the group by remote control, only one step. Anyone can do it in 2 minutes. Except project, The magic wand serial will be perfect product for your retail distribution channel.

If necessary, the magic wand smart lamps can link to HOMA’s SAAS system by gateway to get more digital data, such as energy, failure alert, lamp life.

The magic wand serial include panel, linear light, tri-proof light, high bay, LED tube. This kind of smart lamps can be used for industrial and commercial area, example offices, warehouses, factories, parking and others.

We are dedicated to providing the best intelligent lighting products and system for all of you. And we hope we work together to build a clean and beautiful world.
