Description

A health intelligent education lighting device

technical field

The invention relates to the lighting field, and specifically designs a health intelligent education lighting device.

Background technique

Among the nearly 600 million myopia patients in my country, teenagers are the "hardest-hit areas" of myopia. The poor vision rate of primary school students nationwide is 28%, that of junior high school students is 60%, that of high school students is 85%, and that of college students is as high as 90%. According to the survey of the National Center for Disease Control and Prevention, in addition to some congenital inheritance, poor classroom lighting environment is one of the important reasons for the decline of students' vision.

At present, the lighting environment of some schools is not good, mainly in the following aspects:

The illuminance of blackboards and desks is generally lower than the illuminance stipulated by the national standard. Taking most of the current classrooms as an example, due to the serious light decay of fluorescent lamps, after a period of use, the average illuminance of the blackboard [light intensity : Refers to the luminous flux of visible light received per unit area] only 200-300LX [lux], lower than the national standard of 500LX, the average illuminance of the desktop is only 150-250LX, lower than the national standard of 300LX, on the one hand, the illuminance does not meet the standard, on the other hand, the illuminance Uneven, with obvious dark areas. Students study in an environment with low illumination and uneven light for a long time, which is easy to induce myopia.

The bracket fluorescent lamps in the classroom, all the lamp tubes are exposed, students can inevitably see the direct glare of the lamp tubes while watching the blackboard, which will cause eye discomfort, tearing, and lead to vision loss.

Fluorescent lamps are generally equipped with magnetic ballasts, which have a serious stroboscopic effect. Fluorescent lamps will "flicker" 100 times per second. The visual system will adjust too frequently for changes in the applicable frequency, causing the pupillary sphincter to keep opening and closing. , so that the eyes appear sore, pain and other symptoms, it is bound to cause visual fatigue.

Classrooms generally use 6500K fluorescent tubes with high color temperature. The illumination is low, the light color is cold, and the color rendering index is low. The color of things is not real, which is also a factor that causes visual fatigue.

The classroom lighting environment with substandard illumination, direct glare, stroboscopic effect, cold light color, and low CRI seriously endangers students' visual health.
