Application of wireless technology in LED lighting

Liang Qirong, engineer manager of Westpac Electronic Technology Co., Ltd., said that in the European and American markets, there is already a mature central monitoring lighting system, and China's lighting market is not mature, limited to simple operation procedures such as opening and closing, so it is very Development space.

As a major feature of intelligent lighting, in fact, wireless control has been applied to lighting control as early as 2005, but due to various technical bottlenecks and cost constraints, it has become the mainstream of the market until now. The biggest challenge of wireless control is how to ensure the stability and accuracy of wireless transmission and reception, as well as the problem of automatic connection. Compared to wired power carrier (PLC) transmission methods, wireless transmissions need to constantly face interference from various environmental factors.

Currently, the mainstream wireless transmission standards in the market include Zigbee, Bluetooth, and WiFi. Liang Yurong said that Bluetooth has a short transmission distance and few transmission channels; WiFi consumes a lot of power and equipment costs are high; therefore, for home lighting only, Zigbee has both technical and cost advantages.

Weibo's LED wireless lighting solution adopts the currently popular Zigbee standard and cooperates with TI to develop a control network platform. Liang Rongrong introduced that after more than ten years of research and development by the R&D team in Australia, Weibo Technology has launched a variety of LED lighting solutions to successfully overcome the stability and accuracy of wireless transmission and reception, and can be China. Manufacturers provide technical services from research and development to direct production.

For Chinese manufacturers, due to the high threshold of wireless technology, ordinary production engineers face many difficulties in debugging and application. In this regard, Liang Haorong said that Weibo Technology's LED wireless lighting solution can provide production testing and other services, and specifically launched a platform called "PSWnetwork" for ordinary engineers to solve various technical problems at any time.

When is LED lighting popular?

Due to the shutdown of the nuclear power plant after the earthquake, the lack of electrical energy made the Japanese accident a major market for the global popularity of LED household lighting. And because of the main reasons such as cost, when LED lighting can be widely used locally, it has become a big mystery.

Liang Qirong analyzed in detail that since the price of LED lights is declining every quarter, if the current average rate of decline is estimated, after about 2-3 years, when the cost reaches 0.7-1 times of the price of ordinary lamps, It has been fully popularized in the homes of the people.
