Since entering the Chinese market in the 1990s, the intelligent lighting industry has been in a slow development trend due to market consumption awareness, market environment, product prices, and promotion efforts. A unique advantage of LED products for home lighting is the creation of a comfortable, energy-efficient lighting environment through intelligent control. 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 the ultimate interest point of LED lighting.
The energy-saving effect is no longer the ultimate interest point of LED lighting. The future LED lighting competition is more reflected in the intelligent demand.
In recent years, many international first-line lighting brand enterprises have begun to lay out intelligent control fields 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 targeted LED lighting control solutions last year through the acquisition of Encelium Technologies, a company with a cutting-edge commercial building lighting control software system. At present, although some enterprises in China have introduced smart lighting products, most of them only stay in simple dimming.
In fact, the concept of intelligent lighting goes far beyond this.
Xu Chen said that there are two main concepts of intelligent lighting: one is to change the light through sensing, to let light adapt to people; the other is to use light as the transmission medium and human 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.
Market chaos At present, intelligent lighting products on the market mainly achieve intelligent effects by using the control function of the driving power supply, and the technology itself is not difficult. At the same time, the demand for LED intelligent lighting in the domestic market is not high. According to the research data of the High-tech LED Industry Research Institute (GLII), the penetration rate of intelligent LED lighting in China is still less than 2, and the application of the products is mainly reflected in the dimmable LED landscape lights, the color-adjustable LED street lights and their monitoring. .
At present, the research on intelligent lighting by domestic enterprises mainly stays in the LED dimmable color lighting products, and there are few manufacturers that actually carry out systematic LED intelligent lighting. Zhang Longxin admits that the current domestic LED lighting companies do not understand the concept of intelligentization. Domestic enterprises are blindly pursuing intelligence and focusing on immediate interests. The international understanding of intelligence is mainly from the coordination of people and the environment. As a starting point.
Energy saving and environmental protection, but the market is always no shortage of followers. In this regard, some people in the industry have their own views: on the one hand, because intelligence is an inevitable trend of market development, on the other hand, the so-called intelligent lighting products on the market are not costly, and the profits are not low.
According to GLII research data, the cost of an LED driver with intelligent control function is less than 5 yuan, and the ex-factory price of lighting fixtures with such power supply is 20-30 higher than that of ordinary lamps. The insiders have calculated the account for the reporter. Only one of the above intelligent configurations can increase the gross profit of the lamps by at least 20, and some high-end dimmable products can even reach 30 or more.
At present, the enterprises that arrange intelligent lighting in China are mainly emerging LED lighting companies. Shenzhen Juju Industrial Co., Ltd., which is mainly engaged in the Japanese market, has sold nearly 30% of its total sales in 2011. Xiao Ling, general manager of the company, said that intelligent lighting (automatic induction, dimming and color adjustment) is now more popular in the Japanese market as a high-end product.
In terms of R&D investment, these companies also spare no effort. Among them, Qinshang Optoelectronics invested a total of 7.65 million projects in LED intelligent street lamps and power key technologies in 2011, accounting for 51.69 of all R&D investment. According to the plan, in 2012, the company will also invest 11.3 million yuan in new research and development. Among the 15 LED lighting companies with a revenue of 100 million in the random survey, 12 related companies accounted for more than 30% of the total R&D expenses.
Considering the factors such as cost and sales volume, traditional lighting companies have not mentioned the intelligent lighting. The reporter did not find the words of intelligent lighting on the public information of listed companies such as NVC Lighting and Foshan Lighting. A traditional lighting manufacturer said that the main reason is that intelligent LED lighting is still in the stage of personalization.
An industry expert said: Although there are already a number of enterprises in China doing intelligent lighting research, but more environmentally friendly is to stay in simple dimming color, and the real intelligence should start from the control system.
Long Road Long Zhang Longxin summarized the development of the LED lighting market into three stages, replacing the traditional lighting stage, integrating the system with smarter, more energy-efficient, cross-industry integration (including Internet of Things, remote control, smart home, etc.). However, the current LED lighting market is mainly to replace the lamp market.
He said that simple intelligent products are not difficult to implement from a technical point of view. However, the current development of LED lighting is still in the first stage, and consumers still have doubts about the quality and reliability of LED products. Therefore, in his view, although intelligence is an inevitable trend in the future, it will take a long time for this market to really open.
Xu Chen also expressed his doubts. At present, technologies such as the Internet of Things, sensor technology, and cloud computing are still in the early stages of development, and various standards have not yet been perfected. Due to the systematic intelligent lighting products, the simultaneous development of multiple technologies is required. Therefore, it is difficult to fully realize in the short term.
At present, many domestic enterprises are hoping to increase the added value of products with the help of intelligence. These concepts seem to be good, but for most SMEs in the country, there is a lack of operability. Hu Sang, sales director of Jiehe Optoelectronics, said that the current concept of intelligent lighting is limited to some large enterprises, as well as enterprises with technical backgrounds such as communication and sensing. Large enterprises can do technology research and development with their financial strength, and carry out large-scale promotion with their brand influence, changing consumer habits, which are not possible for most domestic enterprises.
There are also many people in the industry who say that LED intelligentization needs to be promoted. First, there must be government guidance, establish demonstration projects, and go step by step. At present, there are a lot of demand for LED intelligent lighting on the market, such as office buildings, commercial buildings, and star-rated hotels.
For the blind follow-up of many LED lighting companies in China, Professor Wen Yuanmei of Guangdong University of Technology said that enterprises can start from the driving power supply and introduce functions such as deployment, management and communication through the introduction of intelligent control.
