Wireless communication technology in the field of intelligent lighting applications

ZB Alliance (ZigBee Alliance) announced that it is developing a new open standard LED lighting control ZigBee Light Link. Upcoming this standard will help manufacturers develop a variety of lighting and control products, so as to bring a variety of distributors and consumers of interoperable wireless control home lighting products. The Alliance is developing this standard and the alleged use of ordinary dimmer switch will be as easy. Using ZigBee Light Link bulbs, LED chandelier lamps, sensors, timers, remote controls and switches do not need special equipment to cope with the home network. Users can easily complete the installation.

For energy management, commercial and consumer applications, creating wireless solutions for global business alliance ZigBeereg; Union (ZigBeereg; Alliance) 18 declared, ZigBee Light Linktrade; standards development and certification has been completed.  The chandelier lamp industry now has a broad business alliance to provide support for an open global standard for some of the world's most economical and flexible LED lighting solutions provide wireless control.

Compared with Bluetooth, ZigBee simpler, slower speed, power, and costs is lower. Its basic rate is 250kb / s, when reduced to 28kb / s, the transmission range can be extended to 134m, and higher reliability. In addition, it can be networked with 254 nodes. It can better support than Bluetooth Games, consumer electronics, instrumentation and home automation applications. People expect that the industrial monitoring, sensor networks, home monitoring, security systems and toys and other areas of ZigBee applications.

Each ZigBee network can support up to 255 devices, which mean that each ZigBee device with another 254 devices can be connected. The effective range is small. The effective coverage of 10 ~ 75m, specifically between the actual transmit power based on the size and variety of diverse applications is mode dependent, essentially to cover ordinary home or office environment. It's flexible working band original position. Bands used were 2.4GHz, 868MHz (Europe) and 915MHz (USA), are unlicensed bands.

Compared with Wi-Fi, ZigBee’s low power consumption and low cost have a very considerable advantage in low-power standby mode. Two ordinary 5 batteries can be used more than 6 months. This is also the ZigBee supporters have been proud of the unique advantages. Because ZigBee data transfer rate is low, simple protocol, so greatly reducing the cost.
