Introduction

With the advent of the information society, the acquisition of information has become a core element of human life, study, work, growth and development.

More than 80% of information is acquired through vision, so visual health not only affects people's physical health, but also affects people's life, study, work and life.

It plays an important role in production and growth.

As a new type of light source, LED has been widely used in lighting, display and other related lighting products. "Light health or healthy lighting" has become The impact of LED lighting on human visual function has become a key and hot issue of common concern to the whole society.

Especially in the context of the comprehensive implementation of myopia prevention and control for children and adolescents in China. How to objectively and quantitatively evaluate the photobiological effects of light on the human body?

response characteristics, so as to find out the health effects of LED lighting products on the human body (human visual system) under different light quality characteristics, and then study Producing lighting products that can maximize the visual health and safety of consumers has become a major goal in promoting industrial technology development, improving product competitiveness, It is an important way to ensure visual health, effectively promote the Healthy China strategy, and strongly support the prevention and control of myopia among children and adolescents.

LED visual health and comfort is based on the light biological response characteristics of the human body, and is measured by cell molecular tests and objective physiological indicators.

The health effects of LED lighting products on human body are comprehensively evaluated by means of testing and biochemical analysis of neurotransmitters.

It can effectively regulate the healthy lighting market and help domestic enterprises develop healthy lighting products with independent intellectual property rights.

It has played a positive role in promoting China's creation and occupation of the international market, and helped China's semiconductor lighting industry occupy the "people-oriented" lighting market.

The implementation of this document can promote scientific use of light, improve the health of the people, and effectively reduce the Prevent visual impairment such as myopia caused by lighting and reduce public medical costs.
