LED smart lighting: present and future

Lighting will be networked, and the release of infinite value, the future of LED smart lighting will be able to interact with people"...... On May 13-15, the seventh Shanghai international new light & New Energy Lighting Forum sponsored by the union meeting, the forum of "intelligent lighting system and service branch branch, from Rensselaer Polytechnic Institute in the United States, intelligent lighting engineering research center, PHILPS Research Institute, Chinese international ZigBee alliance heavyweight guests and a large number of domestic enterprises on behalf of the application and development of the present market trend of intelligent lighting, combined with the theme of the current LED intelligent control standardization and promotion experience in-depth discussion and exchange. LED intelligent lighting has begun to enter our lives, and in the future with the progress of the Internet of things, optical communications and other technologies, LED smart lighting will occur will bring more changes.

LED into the era of intelligent lighting

Mobile phone or iPad remote control LED lamp; by manually setting even intelligent memory function, adjust the lighting mode in different time and scene, let the family atmosphere lighting switch; from indoor lighting intelligent outdoor lamp control...... As the advantages of LED field, intelligent lighting is considered to be an important growth point to increase the added value of semiconductor lighting, is attracting a large number of enterprises to join, LED intelligent lighting has become one of the main technical development direction of semiconductor lighting enterprises.

The current LED intelligent product applications are mainly reflected in adjustable light, color temperature and monitoring, such as street lighting control. But LED smart lighting will be more than this, the United States Rensselaer Polytechnic Institute intelligent lighting engineering research center of innovation director SilviaL.Mioc said, intelligent lighting lighting industry makes the transition from capital equipment model to the service model, increase the added value of products. In the face of the future, the best advice is to see how to reshape the lighting to become an integral part of the Internet, health, energy, services, video, communications, etc.. The development of the Internet of things, intelligent building, etc., will also give LED intelligent lighting greater play and innovation.

Among them, the Internet is the Internet (IP) as the core and foundation of the real world, digital, connect from person to person and things to communicate with people, build a sustainable and a full range of modern information society infrastructure platform. In this process, a new generation of IT technology will be fully used in all walks of life, to promote cross sectoral integration across the system. The networking architecture and supporting technology, from top to bottom are the perception layer (including driver and sensor etc.), network layer, platform layer (including cloud computing, data analysis and management), application layer (including intelligent lighting, public security, transportation, health, etc.).

PHILPS Research Institute chief researcher Dr. Chinese, Wang Jianfeng said at the meeting, from the traditional CFL, eHID to LED, from magnetic ballast to today's digital drive, from the past to the integrated functional lighting, dimming, artistic lamps, from simple switch dimming to distributed network based on intelligent dimming, it can be said that from the module to the light source, lamps, lighting systems, have occurred in the field of the digital revolution, and in this process, things can be put forward again to promote digital lighting or upgrade to a new stage. The past innovation in the field of lighting is more focused on the light source and module, and now focus on the integration between the system and the system, such as the integration of lighting and intelligent buildings, smart city, interoperability. The future will develop to the application of the service phase, focusing on people's physical and psychological. From the value chain, people used to use the light to see or make themselves more visible. Now began to focus on the decline in the total cost, and the future of the user experience, health, safety and lifestyle will become the embodiment of the value of lighting. The Internet of things will become a bridge of connectivity, bringing lighting and smart city / building / home integration".

In addition, in addition to application integration with other systems, LED light source supporting intelligent lighting technology including multi channels, and can monitor the wavelength range of the sensor, control technology and upgrade by visible light communication also will give the development of LED intelligent lighting to bring more people look forward to the "variable".

Standards become the cutting edge of organizational power

Looking at the current LED intelligent lighting applications, mainly in intelligent control, and still faces many problems, such as the maturity of technology still need to improve the system, the need to reduce costs, networking application of universal platform construction. In addition, the standard is an important issue facing LED intelligent lighting. Among them, the intelligent outdoor lighting network is widely used, there is a problem because of the lack of relevant standards, is still in the development stage, the manufacturers in the technical realization still cannot achieve interoperability, contention of a hundred schools of thought, many LED companies developed their own LED outdoor lighting system platform, it is difficult to integrate with other products, so it is difficult to form complementary advantages that is very easy to cause the resource waste and it is difficult to integrate.

In this context, LED intelligent lighting in the field of organization is becoming more and more prominent, more become a way for enterprises to participate in the competition, while the standard of LED intelligent lighting related has become a large number of organizational strength of the entrance. As of June 2012, Dongguan KingSun Au Optronics Co, Harvard Engineering, PHILPS, Schneider, Streetlight.vision and Fort ord initiated and involved in the formation of the TALQ alliance, aimed at the development of the central management system and outdoor lighting network system (OLNs) standard application interface between Co
