With the continuous optimization and improvement of the educational environment, educational lamps, as the core lighting equipment of learning spaces, have attracted more and more attention in their functions and designs. Among them, the function of adjusting brightness is particularly important in educational lights, because it is directly related to the comfort of the learning environment and the visual health of students.

In different time periods, people have different needs for light intensity. During the day, sunlight shines into the classroom through the windows, and there is sufficient natural light. At this time, if the brightness of the educational lamp is too high, it may contrast with the natural light, causing a dazzling feeling and causing unnecessary irritation to students' eyes. Therefore, educational lights with brightness adjustment function can appropriately reduce the brightness according to the actual situation, making the light softer and avoiding adverse effects on students' vision.

At night or in a dark environment, the brightness of the educational lights needs to be increased to ensure adequate lighting. At this time, if the brightness of the educational light is too low, it may cause blurred vision, increase the burden on the eyes, and affect students' learning efficiency. Therefore, by adjusting the brightness, educational lights can provide brighter and clearer light, helping students learn and read better at night or in dark environments.

In addition to adapting to the light needs of different time periods, personal visual needs are also one of the factors that need to be considered when adjusting the brightness function. Everyone's visual experience is unique. Some people may like bright light, thinking it can improve concentration and alertness; while others prefer soft light, thinking it helps relax the body and mind and improve learning efficiency. Therefore, educational lights with brightness adjustment functions can provide personalized lighting experiences based on personal preferences and actual needs to meet the needs of different groups of people.

The ability to adjust brightness is crucial for educational lights. It can not only adapt to the light needs of different time periods, but also provide a personalized lighting experience based on personal preferences and actual needs. Therefore, when choosing educational lights, we should pay attention to its brightness adjustment function and choose products with high quality and reliable performance to ensure that students can learn and grow in a comfortable and healthy environment.
