Human-centered light environment design
The study of light environment was born out of human needs, and human pursuit of light has driven the continuous development and innovation of lighting and daylight utilization technology.
With the gradual clarification of human physiological and psychological response mechanisms to light environment stimuli, the health benefits of light in various aspects of “vision, rhythm and emotion” have been continuously discovered, and human factors lighting-related research, design and application projects have emerged in large numbers, and gradually from the study of human capabilities and limits of availability to a comprehensive focus on human physiological and psychological needs The research, design, and application projects related to human factors lighting have been proliferated, and gradually expanded from usability research on human capabilities and limits to comprehensive research on human physiological and psychological needs.
In 2016, the European Lighting Association released its 10-year strategic roadmap, which puts forward the core development concept of “human-centered lighting” and confirms the strategy to improve the quality of lighting through LED products, intelligent lighting systems, as well as human-centered lighting and circular economy to make it a new driver of growth in the European lighting market, and will develop policies to Support the development of human factors lighting-related industries.
Taiwan’s Industrial Technology Research Institute (ITRI) has set up the LED Human Factors Lighting Laboratory and conducted research projects such as “LED Intelligent Human Factors Lighting Research to Improve Work Performance” and “High Value LED Human Factors Lighting Research for Healthy Home Lighting at Night”, and released the “LED indoor human factors lighting system and Android body remote control system composite human factors intelligent light environment system” and other application products.
Technology will eventually return to people-oriented and focus on human health and well-being, and human factors engineering will also lead the future of light health research and practice.
People read in dim light or shadow, write on strongly reflective paper, and work in front of a high-brightness electronic screen …… These ergonomic lighting will cause eye fatigue, blurred vision, headaches and general discomfort, resulting in reduced operational performance, mental alertness and many other problems.
Long-term flicker, unsuitable illumination, uneven light distribution, strobe, glare light environment, will produce visual damage and other more serious consequences. It can be seen that ergonomics in the design of the light environment can not be ignored.
Systematic thinking is the beauty of ergonomics. Ergonomics in the light environment is a comprehensive study that takes into account visual characteristics, operational tasks, environmental conditions and the coordination between them. The purpose is to make people easily and accurately identify visual targets, complete visual tasks with high performance, create a light environment that meets maximum comfort while protecting visual health, and avoid physical damage caused by poor lighting conditions to ensure safety.
Smart lighting will become more common in the future, and the diverse ways of interaction between people and the light environment and its luminous interface have become the key elements of light health human factors research.
