After studying in the student days and working after graduation, people spend most of their time in the room every day. The importance of indoor lighting to people is self-evident. When I was a child, my parents often told us not to read in the sun, not good for my eyes. All children know that they can't read in the sun, but forget that bad indoor lighting is quietly hurting our eyes.
First, the importance of office classroom lighting
1. The classroom lighting environment is one of the important reasons for the decline of students' vision.
In 2015, the National Health Vision Report released by the China Center for Healthy Development of Peking University pointed out that the incidence of myopia in young people in China has ranked first in the world, and the incidence of myopia among high school students and college students is over 70%. Among the college entrance examination students in many cities in China, there are up to 90% of myopia.
There are many reasons for the decline in students' vision, such as congenital factors, incorrect sitting posture, excessive learning burden, watching TV or operating the computer for too long. However, poor classroom lighting environment is one of the important reasons for the decline of students' vision. According to the survey conducted by the National Center for Disease Control and Prevention, the direct cause of the decline in students' vision is caused by the poor light environment of the school. Young students, especially those with visual acuity during development, have long been in a light environment that does not meet the requirements. Studying nervously, suffering from unbearable light pollution, vision will certainly be affected.
2, work efficiency is directly limited by environmental lighting conditions
Vision determines the efficiency of work, people get information from the outside world through vision, and the degree and quality of rapid response, work efficiency, are directly limited by the lighting conditions of the environment. There are many aspects of environmental lighting factors that affect vision. Among them, illuminance level, brightness distribution, color appearance, light and shadow color, etc., and these factors have different effects on work efficiency. Good office space lighting needs to focus on the health of office workers, and choose lamps and lighting.
Second, what kind of light is suitable for office classroom lighting?
Good lighting conditions are one of the important factors to reduce the decline of students' vision. In addition to saving energy, office classroom lighting should also pay attention to the improvement of classroom lighting quality. The most important function of office classroom lighting is to improve the efficiency of work and study, and also to ensure that the lighting source does not cause visual fatigue and damage under long-term use. What kind of light is suitable for office classroom lighting, there is currently no conclusion in the academic world. An important reason is the lack of research light sources.
