Domestic: At present, classroom lighting standards in China are generally implemented in accordance with Building Energy Efficiency Standards and School Hygiene Standards. In recent years, with the wide application of LED lamps, many studies have discussed the effects of different light sources and lighting parameters on students' vision, learning effect and comfort. In addition, some research focuses on the energy-saving performance and intelligent control of lighting system.
Abroad: In developed countries such as Europe and America, the research on classroom lighting has been relatively mature. They generally adopt international standards or self-made standards to regulate classroom lighting. In addition to similar visual and learning effects in China, they also pay more attention to the influence of lighting system on students' health and psychological state, including emotion, alertness and biological rhythm. In addition, there are some leading technologies and research achievements in intelligent control and sustainable development.
Generally speaking, the research trend of classroom lighting is to improve lighting quality and save energy, and gradually pay attention to the influence on students' physical and mental health.
