Biography

Professor Luoxi Hao is the vice-president of CIE, member of ISC-CHINA, invited vice president of China Illuminating Engineering Society, and member of the senior committee of experts of China Association of Medical Equipment currently. Professor Hao has been engaged in the teaching, scientific research, and engineering practice of light and human health for a long time.

In recent years, Professor Hao has led the collaboration between medical and industry, gathered interdisciplinary talents, established the "International Health Design Joint Innovation Group", developed a research platform for environmental human factors, undertaken scientific research projects such as national defense science and technology innovation, national natural science foundation of China, key research and development program of the ministry of science and technology, and carried out evidence-based research and application of human health in human settlement environment. Professor Hao participated in China's 29^th Antarctic scientific expedition and completed the high-fidelity anthropogenic health lighting polar experiment at Great Wall Station personally. It takes the lead in proposing intelligent health lighting technology for defense the deep sea and coping with confined stress environment.

Focuses on the polar day and polar night environment in the Antarctic initially and study the intelligent human factors health support system to promote the research crews physical and mental health adaptation to extreme environment. Professor Hao established the theory of "environmental healing and active health lighting intervention" and the key technology system of "visual performance-physiological regulation-psychological intervention". The standard parameters and index thresholds values of ecological health city lighting is put forward, which provides scientific support for the establishment of standard control. The research results have been applied in demonstration and won the first prize of Science and Technology Progress of China National Light Industry Council, the second prize of Shanghai Science and Technology Progress and other awards.

She has published more than 100 papers, eight monographs and nearly 30 national patents. Professor Hao has published the academic monograph "Light and Health", one of the key publications of Shanghai, and organized the global training of the important publication CIE S026.

Outstanding Contribution Brief

Professor Luoxi Hao leads an interdisciplinary team to carry out research on the health lighting human settlement environment theory and evidence-based design method and establishes a medical and industrial cross-collaboration platform for the research on built environment and human health; coordinate and organize project research, research and development, production and application, and enhance industrial promotion of research results by application demonstration; through the performance of duties by international academic organizations, the organization of academic exchanges and health popularization of science lectures, which enhanced the social public welfare value of the achievements and academic influence at home and abroad.

1. Healthy lighting theory and evidence-based design method of human settlements

First, Professor Luoxi Hao broken through the single functional application of light and lighting visual effect, and the multi-dimensional effect of light visual, physiological, and psychological is used to adjust and improve physical and mental condition and improve human settlement health. Due to the multi-factor interaction between lighting environment elements and human health factors, the research content of health lighting is extensive, and the system is complex, so it is difficult to realize the achievement transformation. Therefore, interdisciplinary teams of architecture, urban planning, medical treatment, psychology, lighting industry and electronic information have been set up. The concept of active health intervention based on human living lighting environment was put forward, and the health lighting theory of human settlement environment was developed, including photobiological safety and injury prevention, lighting healing of health imbalance and active intervention of health steady state.

Health lighting effects can be experienced but hard to quantify, traditional design methods rely on experience to make decisions, lack of empirical evidence and in low reliability, and photobiological mechanisms obtained in controlled laboratory environment, which cannot solve the constraints of complex system design in human settlements. An evidence-based design method for health lighting was established, which was named "association mechanism analysis - high-fidelity human factor experiment - demonstration application and post-use assessment (POE)", and a cross-evidence-based research model for health living was established. Based on the built environment disciplines characteristics and requirements of engineering practice, a set of subjective and objective experimental research paradigm was put forward by Professor Hao to guide the high-fidelity human factor experiment environment  built and self-reported, physiological signal feedback, biochemical index analysis, behavior observation multi-source human factor data collection, to ensure the reliability of the experimental results, the matching between the design objective and scientific.

2. Active health light intervention technology for the differentiated needs of the whole age population and coping with extreme environmental physical and mental stress

Based on the specific population, region, environment and space, Professor Hao started with the response mechanism and model of photobiology, and carried out the whole chain collaborative research of health lighting theory construction and evidence-based design method, key technologies and integrated system of active health lighting intervention, demonstration application and control standard, aiming at strengthening basic research, applied research, development and industrialization of fusion test, shorten from principle to the laboratory to large-scale residential application period of time, make residential health lighting as a science problem theory and technical support, to avoid confusion and misuse caused latent, cumulative irreversible damage to health; as well as to control excessive urban landscape lighting and light pollution that cause physical and mental health problems of people effectively; and form an iterative and updated technical system to maximize the health promotion role of light in the living environment and benefit people's livelihood.

Professor Luoxi Hao is problem-oriented and based on the differentiated health characteristics and health needs of the whole age population, proposes the combination of customized lighting parameters and the whole-time healing lighting scheme, so as to realize the individual and precise active intervention of lighting. At present, Professor Hao has completed research on health intervention lighting methods for children and adolescents' visual health, long-term care for the elderly and the disabled, severe illness, physical and mental healing for surgical patients, emotional support for pregnant women and other application scenarios. At the same time, facing the Antarctic extreme day and extreme night and the stress environment of visual deprivation, Professor Hao proposed the light restoration program with rhythm timing to promote the summer and winter expedition members' adaptation to the extreme environment and physical and mental health. The intervention technology has been proved to be effective through demonstration application.

3. Evaluation technology and control standard of lighting healthy quality and photobiological safety

With special characteristics and urban residential structure in China, the international general standard health lighting products in our country and urban landscape lighting system control has weak operation and implementation as the outstanding problems, Professor Hao based on the situation of our country to construct the built environment health illumination control system of evaluation indexes, with standard lead healthy lighting product development, achievements and application to guide the construction and control of urban nightscape light construction controls.
