LED lighting market development prospects
Compared with traditional incandescent lamps and energy-saving lamps, LED lighting has many obvious advantages such as more energy saving, environmental protection and longer service life. There are two key points in China's 12th Five-Year Plan, namely energy conservation and environmental protection. This also shows the trend of LED lights in the Chinese market. Not only China, but also the incandescent lamp bans in major countries and regions will come into effect in 2014. On January 1, 2014, the United States announced that it will no longer produce 60-watt and 40-watt incandescent lamps. At the same time, Canada is officially banned. 75 watt and 100 watt incandescent lamps. The European Union has completely banned the sale of incandescent lamps in 2012. Looking at the entire lighting market, many chip manufacturers and lighting manufacturers are slowly shifting their focus to LEDs. Although the current LED lights are relatively expensive, as the technology matures and the amount increases, the price of LED lights will drop. When the price drops to a certain level, LED lighting will be widely accepted.
With the development of the IOT industry, intelligent LED lighting has become an important part of the IOT. The definition of intelligence is very wide, and it can be wired, adding dimming and scene binding to the existing lighting base. In addition, as the functions of mobile devices continue to escalate, the use of wireless means to control the lighting is a direction of intelligent lighting in the future. In particular, remote control will bring a lot of convenience to the user. For example, it is also possible to check whether the lamp at home is related to work, and to control it. It also has great significance for energy conservation.
So what is wireless control? It is through the wireless way of smartphone or tablet computer, such as ZigBee, 433MHz, Zwave, 6LoWPAN, WiFi, etc. The switch, dimming and color adjustment control, no wiring, installation is very convenient.
Customers can choose different solutions for different applications. The significant advantage of 433MHz is that the wireless signal has strong penetrability and long transmission distance. It can be selected for simple lighting control, such as controlling the light with a remote control. From the perspective of communication reliability, the 433Mhz technology only supports the topology of the star network, and the network coverage space is extended by means of multiple base stations. Therefore, the reliability and stability of the wireless communication are also inferior to the ZigBee technology. The data transparent transmission protocol is generally adopted in the 433Mhz network, so its network security reliability is also poor. Murata chose ZigBee and WiFi as the IOT wireless solution.
Wireless control lighting system
Murata ZigBee intelligent LED lighting solution
ZigBee has been selected as the solution for intelligent lighting by many manufacturers due to its low power consumption, high anti-interference ability and flexible automatic networking function. However, because there is no ZigBee wireless method in mobile phones and other devices, the ZigBee smart LED lighting now requires an additional gateway to convert the WiFi protocol and the ZigBee protocol.
Murata Smart LED Solution
The solution consists of Murata's infrared sensor, ZigBee module and Murata's newly developed mini-gateway.
