The whole innovation chain will bring about 50 billion yuan in the scale of lighting health follow-up industry

In an era of increasing support for technology, people pay more and more attention to quality of life, health and safety. The demand for lighting is not only used to help "see", but to pay more attention to lighting products. The level of “invisible” influences puts new demands on the health and comfort of the lighting environment.

The whole innovation chain will bring lighting health

On November 20th, the national key research and development plan “strategic advanced electronic materials” key project “Photobiomechanism and application research for health lighting” was quietly launched in Suzhou. It is reported that the total budget of the project is 28.55 million yuan, which is sponsored by the Suzhou Institute of Biomedical Engineering and Technology of the Chinese Academy of Sciences and supported by the High Technology Research and Development Center of the Ministry of Science and Technology.

"The project brings together the strengths of domestic semiconductor lighting and light health research covering optical, human efficacy, clinical medicine and other fields. It brings together the top semiconductor lighting companies in China and provides a solid technical foundation and industrialization foundation for the development of semiconductor lighting industry. According to the relevant person in charge of the Chinese Academy of Sciences, the key members of the team presided over more than ten national science and technology projects during the “Twelfth Five-Year Plan” period. At the same time, according to the needs of the project, they absorbed new superior units and members, including 2 national key laboratories and 3 Provincial and ministerial key laboratories, 2 national engineering centers, 3 provincial and ministerial engineering centers; gathered several top semiconductor lighting companies with an annual output value of nearly 6 billion yuan.

It is understood that the key special project adopts the whole innovation chain idea of ​​“basic research—application development—standard system construction”. By clarifying the photobiological influence mechanism of semiconductor lighting products, the objective physiological index evaluation method is formed, and the health of semiconductor lighting products is given. Improve the technical solutions, realize the industrial application of health lighting, and build a "light health" standard system.

Intelligent virtual visual brain

"Now, ametropia has become China's 'national disease'. Although semiconductor lighting is the most promising new lighting technology, the health of products and the unclear mechanism of photobiological influence on the human body have always been important to its development. Factors." Shi Guohua, a researcher involved in the project, said. He is engaged in the scientific application of ophthalmic imaging and vision at the Suzhou Medical Institute.

Shi Guohua described a number of physiological parameters of the eyeball such as the base refraction, modulation transfer function, and point spread function. To describe the influence parameters of light on vision, more than twenty kinds of equipment are needed to measure.

"We have two ways to go. One is to purchase imported equipment, and we can get results in a short time. But because imported instruments can't do all the data open source, only the results have no process, and we can't conduct standard traceability research in the first time. The other way is to independently develop measuring instruments, and the time is longer, but the data can be open source, laying the foundation for the subsequent standard-setting work. In addition, there are some special testing equipments that can only be independently developed.” Shi Guohua has developed some measuring instruments. And obtained more than a dozen physiological parameters.

“The next step is to integrate the multi-function instruments and quickly measure all the physiological parameters in a lighting environment.” He confidently said, “It is expected that a semiconductor light photo-affecting physiological database with a sample size greater than 12,000 will be formed. The photobio-affecting pathology database with a sample size greater than 1000." Shi Guohua told reporters that through various parameters, combined with deep neural network algorithms, a model of light environmental assessment will be constructed, and a virtual visual brain will be born. This means that future luminaire evaluations will become smarter and faster.

Subsequent industry scale exceeded 50 billion

In terms of application development, researchers will apply for 11 to 12 invention patents, and develop no less than 3 sets of semiconductor lighting products that meet the requirements of light health according to visual safety, health and comfort and light quality requirements, and carry out no less than 5 construction sites. Demonstration of healthy lighting applications, including factories, schools, residential and medical settings.

"According to the research ideas, our ultimate goal in the future is that every family, unit and individual can customize a set of comfortable lighting equipment according to their needs." This is Shi Guohua's expectation.

Cao Jianlin, former deputy minister of the Ministry of Science and Technology, raised hopes for the project: "So many participating units can achieve strong alliances, in addition to the 'soft output' of the light health standard, and hope that there will be some 'hard outputs' that can be designed to meet the nationals. Health lighting fixtures for demand, as well as instruments for light health evaluation."

Tang Yuguo, director of the Suzhou Medical Institute of the Chinese Academy of Sciences, said that the research of the project will play a significant role in the development of China's semiconductor industry and in the international scientific research field, while effectively improving the health attributes of semiconductor lighting products, serving the market and consumption. By.

It is estimated that the project will drive the industrial scale to more than 50 billion yuan, which will play an active role in promoting the breakthrough of homogenization competition in China's semiconductor lighting industry and occupying the new commanding heights of “people-oriented lighting”.
