What kind of lighting fixtures are more conducive to improving learning efficiency in school classrooms?


When it comes to classroom lighting fixtures, you may think of various fluorescent lamps and light bulbs. But in fact, classroom lighting fixtures are professional lighting fixtures for educational lighting. With the development of technology and progress, LED classroom lights have been widely used in various campuses in recent years. Compared to other lighting fixtures, LED classroom lights have the following advantages, which you can learn about.

1. High anti glare quality level: The anti glare quality level of LED classroom lighting is generally better than other lighting fixtures. The impact of classroom lighting selection on children's vision is mainly reflected in glare, so the requirements for anti glare of classroom lighting should be stricter.

2. Suitable lighting: Classroom lighting fixtures can be designed and planned according to the specific site of the classroom.

3. Energy conservation and environmental protection: LED classroom lights are more energy-efficient than fluorescent classroom lights, which means that the electricity saved by LED lights can recoup procurement costs, and have a long lifespan with low light decay, reducing costs and maintenance costs on the other hand.

Due to the aforementioned advantages of LED classroom lighting, priority will be given to replacing such lamps in future classroom lighting renovation. This is both energy-saving and environmentally friendly, effectively reducing operating costs.

Classroom Lighting Standards

1. Excellent lighting and uniformity: According to the national standard, the illumination on the classroom desktop surface should be ≥ 300, the illumination uniformity should be ≥ 0.7, the blackboard should be ≥ 500, and the illumination uniformity should be ≥ 0.8. If some schools fail to meet national standards. Students who study in such a light environment for a long time are prone to Eye strain, which can lead to myopia.

2. Anti glare: According to national standards, the glare value of classroom lights is less than 19, while most school classroom lights use simple fluorescent lamps with direct light sources, which are very harsh and have a glare value exceeding 22. Therefore, excessive tension in the eye muscles seriously affects students' concentration in class. LED classroom lights generally use grilles, and the light source is not direct to avoid glare.

3. Generally, fluorescent lamps have severe flickering and unstable brightness. Learning under stroboscopic light sources requires the visual system to continuously adjust the size of the eyeball and pupil to protect the stability of retinal light intensity and imaging clarity. Learning in this light environment for a long time will definitely make the pupil Sphincter fatigue. And LED classroom lights can achieve no video flashing.

4. Prevention of light hazards such as blue light: Blue light in ordinary light sources can directly penetrate the macular lesion area of the eye fundus, causing irreversible damage to the eyes. Qualified LED classroom lights must be exempt or have no blue light hazards.

5. Low light attenuation and long lifespan: Ordinary lighting fixtures will experience severe light attenuation after six months of use, leading to a decrease in luminous flux and failing to meet the minimum national standard requirements. In order to maintain lighting brightness in compliance with national standards, frequent replacement of lighting fixtures is necessary, requiring long-term maintenance by relevant maintenance personnel, resulting in high maintenance costs and resource waste. And LED classroom lights can reach a lifespan of over 50000 hours and have low light attenuation.

6. Color rendering index: the spectrum of ordinary fluorescent lamp is incomplete, resulting in color loss and color deviation. Far from reaching the national standard Ra ≥ 80, the color reproduction ability is poor, which will directly affect children's color discrimination ability. LED classroom lights can achieve full spectrum lighting, and the Color index Ra ≥ 90.

7. Comfortable color temperature: According to national standards, the color temperature is 3300-5300K. If it is too high, it will cause mental excitement, while if it is too low, it will cause drowsiness. It will affect the secretion of Melatonin in students' bodies, reduce sleep quality and affect learning efficiency.

8. Lead mercury pollution: Fluorescent tubes contain heavy metals such as mercury and fluorescent powder, which can cause great harm to human health. And LED classroom lights do not have this pollution.
