In the 1980s and 1990s, college students were a scarce species, and "a thousand soldiers crossing a single wooden bridge" is a true portrayal of college students. At that time, because there were few college students, the supporting facilities were not very abundant. With the development of the times, many colleges and universities have expanded their enrollment, and the teaching area has more than doubled.
    And with more and more students, many issues that didn't show up began to surface. For example, the problem of educational lighting has now become a chronic illness in colleges and universities.
    Analyze the use of university classrooms, mainly for classes during the day, natural light as the main lighting source, and artificial lighting as the supplement to compensate for areas with insufficient illumination in the classroom when it is cloudy or covered; students' self-study is mainly at noon and evening. A few classrooms are also used for class. Whether it is class or self-study, in order to protect eyesight and improve learning efficiency, students need a good lighting environment.
    However, these requirements for the lighting environment also have a direct consequence, a waste of resources. Therefore, on the premise of ensuring the requirements of classroom lighting, the issue of energy saving in educational lighting needs to be studied.
    There are two main ways to achieve energy saving in educational lighting: one is to use efficient lighting sources or lamps, such as eye protection lamps. Under the premise of ensuring the quality of lighting, the fundamental measure to reduce the power consumption of lighting lies in improving the efficiency of lighting equipment, that is, improving the efficiency of light sources and lamps.
    The other is to study the intelligent lighting system on the basis of the existing lighting fixtures, that is, to fully study the needs of the lighting object, and optimize the operation of the lighting system to achieve the effect of energy saving. In terms of lighting fixtures, many universities are now adopting education lighting, which is more suitable for existing educational lighting needs.
    Resources are the source of social progress. With our resources, our society can develop rapidly. Without resources, we will not be able to do anything. In terms of total resources, China is a large resource country, but because of its large population, China ’s per capita resource occupancy is very small. If we do not improve resource utilization, we will face resource exhaustion in the near future.
    With the rapid growth of China's economy, the energy demand has increased significantly, and the contradiction between energy supply and demand has become prominent. Especially in recent years, the country ’s power consumption and electricity load have increased rapidly. In recent years, two-thirds of provinces (autonomous regions and municipalities) have experienced power shortages or even power cuts, which have severely affected the economy. Social development and people's living standards have improved.
    According to statistics, China ’s lighting electricity consumption has accounted for 10% to 12% of the total consumption. Therefore, improving the efficiency of electricity use will undoubtedly reduce energy consumption to a large extent and effectively alleviate the current situation of China ’s power supply shortage.
    According to the "China Green Lighting Project" proposed by China, lighting power saving has become an important aspect of energy saving. The current energy-saving potential of lighting is very large. Generally, energy-saving solutions can achieve 10-20% savings. Taking a conservative amount of 10%, the value of energy saved in the country is considerable. It is conceivable how important it is in the national economy. .
    Due to the longer lighting time and more lighting places in universities, the proportion of lighting electricity consumption is as high as about 40%. Therefore, the research on energy saving of educational lighting has great potential and practical significance, which will produce huge social and economic benefits. As a place for educating people, the significance of energy saving is not limited to energy saving itself. It is more important to cultivate students' awareness of energy saving.
