"Intelligent lighting" is beginning to show that short-term development is still limited

[High-tech LED reporter Tang Guirong reports]

Recently, it was reported that Philips Lighting is working with glass manufacturers to make LED light into the glass and make the glass an illuminant. Another overseas lighting manufacturer, GE, is also working with construction companies to integrate LED lighting products with architectural design.

“LEDs determine their future intelligent lighting direction with their light source characteristics.” Dr. Xu Chen, deputy director of the Guangdong Provincial Institute of Standardization, said that after 3-5 years, when the LED light efficiency reaches the limit of use, the energy saving effect is no longer LED lighting final interest appeal point. The future LED lighting competition is more reflected in the intelligent demand.

It is reported that a number of well-known lighting companies in the world have expanded in areas other than lighting, taking a diversified route. At present, domestic lighting companies are also beginning to lay out intelligent lighting routes such as sensing, communication and multimedia.

As early as the first half of 2011, Philips Lighting has partnered with Bayer to join the eco-business building program. Through cross-disciplinary collaboration, the program provides a comprehensive range of services and materials solutions for decision makers in the construction industry in building public and commercial sustainable buildings. At the same time, OSRAM also acquired Encelium Technologies last year. The company has a cutting-edge commercial building lighting control software system and is a pawn for OSRAM to become a supplier of Led Lighting Solutions.

Although intelligent lighting is still only a concept, many companies have been doing research and development and layout in this area. An industry expert said to "High-tech LED": "Although there are already a number of enterprises in China doing intelligent lighting research, but more is staying in simple dimming, and the real intelligence should be from the control system. Start."

In fact, the concept of intelligent lighting goes far beyond this.

Xu Chen told the reporter of "High-tech LED" that there are two main concepts of intelligent lighting: one is to change the light through sensing, and let the light adapt to people; the second is to use light as the transmission medium and the person as the receiver. Intelligent lighting is not only to change the illuminant, but to integrate various modern technologies such as communication, sensing, cloud computing, and Internet of Things into the light, not only the effect of light.

According to the high-tech LED reporter, some domestic enterprises have already laid out the concept of smart sensors and multimedia LED lighting. It is reported that Qinshang Optoelectronics has combined sensors with LED street lights, and can directly control lighting using mobile phones; Xi'an Huatian has installed security systems into LED lighting; Shenzhen Mairui Optoelectronics has also incorporated multimedia functions into LED panel lights. And began to promote the pilot overseas.

However, Xu Chen also expressed his doubts: "Because of multiple factors such as price, the concept of intelligence is difficult to fully realize in the short term." At present, the concept of intelligent lighting is limited to some large enterprises, as well as technical backgrounds such as communication and sensing. Business. Mr. Hu Sang, Sales Director of Jiehe Optoelectronics, told Gaogong LED: “These concepts look good, but for most SMEs in China, there is a lack of operability. Only these internationally renowned companies can intelligently use versatility. Lighting is being promoted in large numbers."

In view of the fact that many domestic lighting companies are in a state of blindly catching shrimps, Professor Wen Yuanmei of Guangdong University of Technology has proposed that intelligentization is an inevitable trend in the future development. Enterprises can start from the power supply that currently restricts lighting development, by inserting intelligence. , to set up the tile, to achieve the functions of deployment management communication.

In addition, the future of LED communication technology has also begun to show.

Professor Chen Changyu from Jinan University's Institute of Technology said that from "green lighting" to "green communication" is also an inevitable trend in the future development of lighting. At the 2010 World Expo, “The Eco-House” has become a clue. A LED light illuminates the desktop. Unlike other lighting, the illuminated desktop is full of information.

By embedding the wireless communication capability into the LED lighting installation, by using the semiconductor lighting system to implement high-speed multimedia digital information transmission, it is possible to "download information in a place where there is a light". Chen Changyu said, "The practical white LED communication system has application innovation prospects in many fields, and can be used in the car number recognition system anti-tailing system for mobile phone identification system electronic wallet, large screen information download system, etc. No electromagnetic pollution will occur."
