Description

TECHNICAL FIELD

[0001] The present application relates to a lighting lamp, in particular to a myopia-preventing classroom lighting lamp and a use method thereof. BACKGROUND

[0002] Myopia is a common disease with high incidence and low age. Overuse of eyes and visual fatigue are important factors leading to myopia in students. Poor lighting environment is more likely to cause visual fatigue. Students spend most of their time in classrooms for study. The light and shade in classrooms are particularly important to students' eyes. However, the existing classroom lighting lamps are generally long strip-shaped and have fixed shapes. The illumination range and light intensity cannot be changed. Therefore, the light is strong at the position below the lighting lamp, and weak far away from the lighting lamp or at the corner of the classroom. The light intensity affects students' eyesight and easily leads to eye fatigue and serious glare, affecting the concentration of students. Moreover, the existing classroom lighting lamps cannot adjust the light intensity according to the environment of day, night, cloudy day and sunny day, which not only affects the eyesight, but also reduces the use experience of students.
