Farewell to "Little Glasses" - How to Choose Classroom Eye Protection Lights?

Farewell to "Little Glasses" - How to Choose Classroom Eye Protection Lights?


In recent years, the myopia rate among young people in China has remained high, and myopia is becoming increasingly severe at a young age!

Students spend 60% of their time in school classrooms, and classroom lighting is particularly important for protecting their eyesight.

On March 30, 2023, the Ministry of Education issued the "2023 National Key Work Plan for Comprehensive Prevention and Control of Myopia in Children and Adolescents".

Before the lighting renovation of most primary and secondary school classrooms, fluorescent lamps were used. When the fluorescent lamps were first installed, the lighting was very dazzling, but the overall feeling was very dim and the light was uneven. And the fluorescent lamp has a white light and more blue light components, which poses a blue light hazard; The longer the lamp is turned on, the greater the attenuation of the fluorescent powder in the light source. After prolonged use, both ends of the lamp turn black and the strobe is also severe. Long term reading and writing in such an environment can lead to frequent adjustment of the visual system, which can lead to dizziness, dizziness, and even myopia.

Like our common fluorescent lamps, ordinary LED lamps often have several common faults:

(1) Direct sunlight into the eyes can cause severe glare and easily lead to visual fatigue;

(2) The stroboscopic is serious, which causes the pupil sphincter to keep opening and closing, causing eye fatigue and decreased vision;

(3) Low color rendering index, incomplete spectrum, resulting in color loss and deviation, affecting color discrimination ability and visual development;

(4) Illuminance and uniformity do not meet national standards, resulting in decreased vision for students in areas with insufficient lighting;

(5) The light source has a short lifespan, severe light decay, and frequent maintenance.

The classroom eye protection light is based on the shortcomings of traditional lighting fixtures, continuously optimized and upgraded to produce. What should I pay attention to when choosing classroom eye protection lights? While ensuring basic lighting, classroom eye protection lights should have no flicker, high color rendering index, low glare value, and better illumination and uniformity than national standards.

Taking schools as an example, the "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms" GB7793-2010 stipulates:

(1) The average illumination value maintained on the classroom desk should not be less than 300lx, and the uniformity of illumination should not be less than 0.7;

(2) The blackboard in the classroom should be equipped with local lighting, with an average illumination level of not less than 500lx and an illumination uniformity level of not less than 0.8;

(3) The classroom should use a light source with a color temperature of 3300k~5500k, and the color rendering index of the light source should not be less than 80;

(4) The unified glare value (UGR) of the classroom should not exceed 19;

(5) Under the condition of maintaining an average illuminance value of 300lx, the current value of classroom lighting power density should not exceed 11W/m ², The target value should be 9W/m ²。

Huahui LED eye protection classroom lighting fixtures (including LED eye protection classroom lights and LED eye protection blackboard lights) have a color temperature of 5000K, close to natural light sources, and soft lighting; High color rendering index, good color reproduction ability, and the lighting fixtures have also been designed with a mesh grille to prevent glare. When reading and writing under the light, the vision is clear and will not cause dizziness or eye fatigue.

Huahui Lighting is specifically used for classroom lighting fixtures - LED eye protection classroom lights and LED eye protection blackboard lights, which comply with national standards and maintain an average (constant) illumination of more than 300lx for desks, with an illumination uniformity of 0.7; The blackboard maintains an average (constant) illumination of 500lx and an illumination uniformity of 0.8; If the color rendering index is greater than 90, the color reproduction is high; Adopting grille anti glare design, with a glare value less than 16, not dazzling; The color temperature is 5000K, comfortable and soft; The entire classroom has uniform illumination, no flickering, and no harm from blue light.

It is recommended that schools choose eye friendly and healthy LED lighting fixtures when choosing classroom lighting fixtures. Huahui Education Lighting's classroom eye protection lighting fixtures have high illumination, good uniformity of illumination, no flicker or blue light hazards, and can provide students with a high-quality lighting environment for the classroom.
