Philips launches new black family: PoE system detonates intelligent lighting [Full text]

Philips is one of the earlier technology dynamic lighting turned intelligent interconnection of enterprise, intelligent lighting mainly in the high-end market, specialty lighting applications than more, Philips has recently announced the launch of a new black technology, it is said to this powerful black families as long as there LED lighting places, you can access the Internet.


Philips launches new black family: PoE system detonates smart lighting

"When every light on the ceiling has an IP address, light has precise positioning and navigation capabilities, and its accuracy can reach centimeters, far beyond the WIFI and Bluetooth positioning systems we currently use. For example, In Shanghai, People's Square has 19 subway exits, and Xujiahui has 20 subway exits, people are often dizzy and do not know where to go in. If the lights installed on the ceiling can navigate a correct direction of entry and exit, the convenience is certain. Everyone needs it.” On August 17th, President of Philips Lighting Greater China, Wang Wei, said in an interview in Beijing that the giants of international electronics companies represented by Philips have realized the application of this technology and become human Another breakthrough in the use and use of light. Philips is now ready to launch an LED with Internet access, navigation and positioning in China.

PoE Lighting System: Exploding Intelligent Lighting with Electronic Signal Driving Voltages "In our traditional concept, lights must be wired for connection, but nowadays lights can be connected with network cables. This is the ether we are applying to LED lamps. Power-over-Internet (PoE) technology, the core of this technology is to ensure the current structure of the network while ensuring the safety of the existing network while power supply, to minimize costs.” Philips Lighting China Lighting Design and Application Division General Manager Yao Mengming said.

LEDs can easily work with sensors, wireless communication modules, and embedded processors. This feature allows LED lamps to become smart network sensor concentrators. With an isolated local embedded processor, the lighting system can achieve energy savings. Connecting smart LED lights/sensor concentrators to local area networks (LANs) allows installed LED concentrators to quickly support and leverage the new features emerging on the IoT (Internet of Things), providing adaptation without the need to replace expensive lights Future development of technology.

"PoE is well-suited for powering, connecting and controlling smart LED concentrators over LAN, which reduces the cost of deploying and installing compatible IP equipment, including LED lights and sensor concentrators. Since only one data cable is required, the wiring cost is lower. Low, and no need for a separate power cable, Yao Mingming stressed.

In a PoE configuration, each LED fixture can be a standard RJ45 connector plug-and-play device that has its own IP address and is independently addressable. By connecting a smart LED concentrator (integrated sensor and wireless access point) via PoE, each LED concentrator that emits light can be powered. The PoE connection also allows each LED concentrator to collect information from various sensors and send the data back to the controller. The collected information may include ambient light, temperature, humidity, and anonymous room usage data. For example, an inductive sensor may be used to ensure that the light is turned on only when someone enters the room and turns off automatically when the sensor detects no one. Or, the ambient light sensor supports daylight harvesting, and the LED lighting is automatically adjusted when sunlight is insufficient to maintain lighting.

With PoE operation, the LED lighting system becomes an information network, and users can control the lighting and temperature in their vicinity. The system can access other building services, such as proximity detection sensors, to find the nearest free meeting room.

The US Cisco Systems Inc. previously applied this technology to its products. According to this, Wang Hao, president of Philips Lighting Greater China believes that PoELED network can provide additional benefits for future development, because LED lighting (and integrated smart sensor concentrator) has been deployed in people's places, PoE is the future of LED lighting . This also opens up the human imagination.

Optical Communication Positioning: precise positioning to centimeter <br> <br> Yaomeng Ming expressed Road, intelligent lighting system at this stage, the application of optical communications positioning technology is another important part.

Compared with the currently used wireless LAN (wireless LAN), the visible light communication system can use indoor lighting equipment instead of wireless LAN LAN base station to transmit signals, and its communication speed can reach several tens to hundreds of megabytes per second, and the transmission speed may exceed in the future. Optical Fiber Communication. With a dedicated computer that can send and receive signals and a mobile information terminal, long-distance downloads and uploads of high-resolution portraits and animations can be performed as long as the lights are in the room.

"There are many limitations in radio signal transmission equipment. They are rare, expensive, but inefficient. For example, mobile phones, and millions of base stations around the world help them to enhance their signals, but most of the energy is consumed in cooling. The efficiency is only 5%. By contrast, bulbs used in the world are inexhaustible, especially when domestic LED light sources are replacing large-scale incandescent lamps on a large scale.As long as adding a microchip to any humble LED light bulb, it can turn light bulbs into wireless networks. Transmitter.” Yao Mingming said, “Without WiFi signal, you can get online with a single LED. This has become a reality and will become even more popular in the future.

Based on the visible light communication technology, Philips Lighting took the lead in developing an optical communication indoor navigation and positioning system. "Based on the PoE lamp network IP address and indoor physical address, LED visible light strobe, mobile phone camera and LED light communication and APP, we achieved the use of light for indoor positioning, and the accuracy can reach centimeters." Yao Meng Ming said that as we said before, if we use lights to navigate the subway exits for people, it is that this technology is working.

In this regard, a number of experts, including Zhao Jianping, vice president of the China Institute of Building Research, told reporters that the current outdoor GPS navigation positioning technology is already very mature. However, people spend more than 80% of their time indoors, and the demand for indoor positioning is multiplying, and the demand for accuracy will also be higher. With the gradual maturity of optical communication positioning technology and the widespread application of mobile Internet, the indoor positioning market has been in the early stage of the outbreak. The optical positioning technology of optical communication will be infinitely enlarged.
