The development history and current situation of China's health lighting

Compared with the global lighting industry, the Chinese lighting industry started late in research on health lighting.

In the era when incandescent lamps are the main source of illumination, people's demand for lighting products is to illuminate the environment, and has not considered the "health" needs.

By the 1990s, the Chinese lighting market gradually formed a series of lighting products with energy-saving lamps as the main light source, and the market was in short supply, and no one paid attention to the impact of lighting on human health.

By the beginning of the 21st century, with the intensification of market competition and the deepening of scientific researchers' awareness of lighting products, the concept of “healthy lighting” has been proposed and gradually subdivided into interpretation.

In 2005, Zhongshan Energy Gloves, a manufacturer of energy-saving lamps at that time, launched a neutral daylight color intelligent energy-saving lamp with a color temperature of 4200K, soft color and good color rendering. Interpretation of the health aspects of lighting products. At the same time, Sanxiong Aurora Lighting, which was known for its engineering lighting at the time, also launched the “Healthy Light Use” clinic in 2005, emphasizing a more scientific approach to lighting, starting from the functional requirements and psychological needs of the place of use. Reasonable selection and scientific arrangement of light source and lighting products to create a more harmonious and healthy lighting environment.

In 2006, Sanxiong Aurora and the School of Architecture and Urban Planning of Tongji University in Shanghai jointly launched an analytical research project on vision health and lighting environment for primary and secondary school students, and advocated the concept of using light in campus science.

In 2007, Yan Yonghong, a professor at the School of Architecture and Urban Planning of Chongqing University and a famous lighting designer, a doctoral supervisor in architectural design and theory, architectural optics, increased his research on health lighting. She believed that due to the complexity of the human rhythm system and visual system. Sex, combined with individual differences, is not a fixed pattern, but dynamic, and its form varies with visual work content and users. Yan Yonghong's research takes the theory of healthy lighting to a new level.

In the era of energy-saving lamps as the main light source, although health lighting has received the attention of some lighting researchers and enterprises, but limited by technology and research methods, research on health lighting has not achieved significant results. However, when LEDs became the main source of illumination, research related to health lighting has been greatly developed.

In 2014, China International Semiconductor Lighting Forum (SSLCHINA) proposed that human life will usher in a new era of healthy lighting, intelligent lighting, scene lighting, and signal transmission, and raise healthy lighting to the level of industry development.

In 2017, China International Semiconductor Lighting Forum (SSLCHINA) directly proposed "light quality and healthy lighting". It believes that in addition to driving the transformation and upgrading of the lighting industry, healthy lighting will also drive the development of many industries such as the pan-home industry and high-end equipment manufacturing.

On November 20th, 2017, the key national special research and development plan “strategic advanced electronic materials” special project “Photobiomechanism and application research for health lighting” was quietly launched in Suzhou.
