Realization of intelligent LED lighting

　　Ears and throat are the next intelligent LED lighting to achieve the most important features . By lighting simple network, the network can be controlled by lights on, off, or dimming, this operation will reduce energy consumption. Communication but also for power , maintenance and emergency to provide fast feedback , this information will save overall system maintenance costs. Wireless and wireline communications can work well in different environments , depending on network size and topology . Wireless more suitable for small and large indoor outdoor applications which require a continuous line of sight , the available frequency band and a sufficient transmission power margin . Power Line Communication (PLC) using existing power lines for communication. PLC is ideally suited for the position because of a physical or building walls can not use natural light large municipal class environmental lighting, tunnels, indoor parking lots. All references in communication , reliability is key. If the communication fails, the system would have no benefit.

　　Wireless applications, signal transmission may be Wi-Fi, ZigBee or other often belong to , but not limited to industrial, scientific and medical (ISM) radio frequency standard protocol . Limit power consumption provides network flexibility is essential if the endpoint is using the battery . Figure 2 is a unique application , which is equipped with energy collection frequency (RF) transceiver on a light switch . Toggle switch system to collect energy for generating a DC voltage can be used to support lighting Radiocommunication ("1GHzRF). As long as the signal can cover the light , the switch can be placed anywhere in the room . Without connecting lighting switches , interior design is more flexible, more reliable lighting control .

　　PLC Lighting control method uses existing power lines, after all, high price selection. Due to communicate by maintaining good existing power lines , PLC avoid a lot of trouble , such as a shared communication frequency , performance and maintenance of the network when inclement weather . Range, speed and reliability are critical design PLC.
