Lighting Requirements for Different Age Groups

The lighting needs of students vary with age. Younger children, aged 7 to 12 years, benefit from a combination of direct and indirect light. The direct portion produces modeling shadows that help the perception of distance and three-dimensional objects, while the indirect portion creates good-quality working light and casts the light onto the walls and ceiling to increase vertical illuminance.

For children past the age of 12, contrast conditions become more important. Excessive amounts of direct light can reduce contrasts, whereas a softer type of light (with more diffusion) will increase them. This is where LED lighting shines, as it can be easily adjusted to provide the right amount of light and contrast.

How to Choose the Right Classroom Lighting Design?

Choosing the right classroom lighting design is a critical aspect of creating an optimal learning environment. The design significantly influences students’ performance, comfort, and overall learning experience. Here are several key factors to consider:

1. Light Glare: Glare can cause visual discomfort and lead to decreased concentration and productivity. It’s essential to choose lighting fixtures that minimize glare and distribute light evenly.The Unified Glare Rating is a standard glare rating, and the industry has set a value of 19 for it.
2. Veiling Reflections: These occur when light reflects off surfaces, obscuring details and causing visual discomfort. The lighting design should aim to minimize these reflections, particularly on critical surfaces like whiteboards and computer screens.
3. Light Distribution: Even light distribution across the classroom ensures that all students have adequate lighting, regardless of their location in the room. This can be achieved by carefully positioning light fixtures and choosing the right types of lights.The optimal lux rating for classrooms has to be 500, and each corner of the classroom should receive an equal amount of light. The minimum illumination rating for classrooms, as per experts, has to be around 60%- 70%.
4. Light Flicker: Flickering lights can cause headaches, eye strain, and concentration difficulties. LED lights are a good choice as they provide steady, flicker-free illumination. There’s no specific industry standard mentioned, but it’s important to note that low-frequency flickers might not be noticeable through the eye, they initiate various nervous system responses.
5. Direct and Indirect Light: A combination of direct and indirect lighting can create a balanced, comfortable environment. Direct lighting is focused and bright, ideal for tasks requiring high visibility, while indirect lighting softens shadows and reduces glare. It’s important to avoid dark ceilings to prevent casted shadows over tasks and boards inside the classroom.
6. Object and Face Modeling: Good lighting design should illuminate faces and objects three-dimensionally, making them easier to see and understand. This is particularly important in a classroom setting where visual communication is key.
7. Color Rendering Index (CRI): A high CRI value means that the lights show the true colors of objects. This is important in classrooms, especially in art or design classes where color accuracy is crucial. The natural light you see during the day (i.e., daylight) has a CRI of 100%. Therefore, classroom lighting CRI has to be around 80% at least, but the recommended level of CRI is somewhere near 90% (preferably over).
8. Uniform Illuminance: Uniform illuminance ensures that there are no overly bright or dark areas in the classroom, providing a comfortable visual environment for all students. For a uniform horizontal illuminance inside the student zone, minimal shadows and flexibility affect task visibility. The illuminance of different planes, including vertical surfaces, is highly important.
9. Color Appearance: The color temperature of the lighting can affect mood and productivity. Warmer colors tend to be relaxing, while cooler colors can increase alertness and concentration.Ideally, classrooms should have adjustable color temperature controls to adapt to different times of the day and different activities.
10. Luminance Contrast: Luminance contrast, also known as brightness contrast, refers to the difference in the amount of light emitted or reflected by an object compared to its surroundings. It’s a measure of the difference in perceived brightness between two areas. In the context of lighting design, luminance contrast is important because it affects how well we can see and distinguish objects and details. High luminance contrast can make objects stand out and appear more distinct, while low luminance contrast can make objects blend in with their surroundings and appear less distinct. In a classroom setting, luminance contrast can affect the visibility of educational materials and the overall visual comfort of the space. For example, a black text on a whiteboard has a high luminance contrast, making it easy to read from a distance. On the other hand, if the luminance contrast is too high, it can cause glare, which can be uncomfortable and cause eye strain. Therefore, achieving the right balance of luminance contrast is crucial in classroom lighting design. It’s important to ensure that the contrast is high enough to make educational materials easily visible, but not so high as to cause glare or discomfort.
11. Flexibility: As mentioned earlier, different classroom activities may require different lighting conditions. Therefore, having a lighting system that can be easily adjusted or controlled can be highly beneficial.
12. Budget: Last but not least, the cost of the lighting system is a key consideration. While initial purchase costs are important, it’s also crucial to consider the long-term operating and maintenance costs.

In addition, the EN 12464-1:2021 standard provides specific lighting requirements for different tasks and activity areas in classrooms. For example, for general classroom activities, the lux level should be 500 with a glare rating of 19 and a uniformity of 0.60. The color rendition should be 80. For black, green, and white boards, the lux level should be 500 with a glare rating of 19 and a uniformity of 0.70. The color rendition should be 80.
