5 requirements of classroom lighting design

The role of lighting in knowledge acquisition and the process of learning is fundamental. It enables visual exploration of the physical characteristics of the study subjects as well as discovery of concepts from written and graphical displays on paper, computer, and projection. Lighting also sets the scene for listening, verbal communication, social skill development, and comprehension of situations. As a critical element of the design that greatly influences how well the space meets the needs of students and instructors, classroom lighting should support health, well-being, and performance by providing a comfortable, attractive environment for students and instructors. Beyond enhancing occupant satisfaction and supporting the educational experience within the illuminated space, lighting in schools and educational facilities should be delivered within tightening code constraints.

According to a large number of surveys, the existing conditions and common problems of school lighting are as follows:

  1. Serious lack of illumination

At present, the illumination of many classrooms in schools is not up to the standard. Students are learning in the low-illumination environment for a long time, which is easy to cause eye fatigue and affect their eyesight over time.

  1. Uneven light and shade

The illumination of desks and blackboards is uneven, especially the average illumination of the blackboard is generally lower than the average illumination of the classroom desks.

  1. Severe glare

In many schools, the light source of classroom lamps is directly exposed, and the light shines directly into students’ eyes, which is very harsh and serious glare.

  1. Color temperature is too high

The standard color temperature for classroom lighting is generally 3300-5300K. However, according to a large number of surveys, many classrooms reach 6000K, and the color temperature is too high, which ultimately affects the secretion of melatonin in students and thus affects the learning efficiency.

  1. Lower color index

After measurement, the color rendering index of most classrooms is about 70 which is not qualified, especially the art room has a higher requirement for color rendering index.

  1. Severe stroboscopic

There is serious stroboscopic lighting in the classroom, which has a great impact on vision.

  1. Harmfulblue light

Low-quality LED products contain excessive amounts of blue light.

Classroom lighting may be deemed of high quality if it contributes to a stimulating learning environment and enables students and instructors to accurately, comfortably and efficiently perform visual tasks. In general, classroom lighting design needs to pay attention to the following points:

1.Illuminance and uniformity

The average illumination value of desks in classroom lighting is more than 300lx, and the uniformity is more than 0.7. Maintain the average illumination value of the blackboard surface ≥500lx, uniformity ≥0.8.

2.Color temperature

According to the standard, classrooms should use light sources with a color temperature of 3300 ~ 5500K, with a color rendering index of 80 or higher, and special classrooms with a color rendering index of 90 or higher.


The damage level of blue retina should reach no harm (RG0).


According to the latest regulation, classroom lighting uniform glare value should reach to UGR≤16.


The stroboscopic index is defined according to the depth of light fluctuation, which is related to the working frequency of the lamp. The stroboscopic index of professional LED educational lighting is less than or equal to 3.2%.

In recent years, the demands on light in classrooms have increased. It is no longer enough for lighting to simply provide brightness; it must also create an ideal learning and teaching atmosphere. Billionaire Lighting brings daylight into the classrooms, brings the biorhythm into harmony with nature and thus increases pupils’ well-being and performance.
