Adequate classroom lighting is paramount for students’ performance, necessitating carefully selecting an optimal design. The primary objective is establishing a lighting system that seamlessly integrates with the classroom’s architecture, environment, and tasks, ensuring functional harmony. Just as social communication and overall health safety are integral to human needs, visual comfort is a fundamental requirement for a productive working or learning environment.

Despite the awareness of potential dangers and eye health risks associated with improper lighting, many school teachers and officials encounter challenges in developing an ideal classroom lighting design. To assist in this endeavor, here’s a concise checklist of factors that demand consideration to ensure the safety and well-being of school students.

Light Glare

The industry has established a standard glare rating, the Unified Glare Rating, with a set value 19. It’s crucial to understand that glare significantly influences the visual comfort experienced by students under task-associated or general lighting in classrooms. While the rating needs to remain lower for light-sensitive tasks, it can be higher than usual for areas like corridors.

Veiling Reflections

While veiling reflections may have caught your attention numerous times, understanding the science behind them is essential. The magnitude of veiling reflections is vital in affecting visual comfort and the quality of results for light-sensitive tasks.

Veiling reflections occur when glossy reading materials or specular surfaces reflect bright luminance patches. The drawback of veiling reflections is their ability to obscure details and limit the contrast of the task.

Light Distribution

The selected lighting system should ensure uniformity, regardless of the chosen angles or LED technology. While the recommended lux rating for classrooms stands at 500, every corner of the school must receive an equal and no less than the optimal amount of light. According to experts, the minimum illumination rating for classrooms should ideally fall within the range of 60% to 70%.

Given that students typically sit with sightlines parallel to windows, this positioning may elevate the lux rating they experience. However, this heightened brightness can become a potential source of distraction when attempting to focus on the chalkboard. The resulting glare has the potential to disrupt focus and impede concentration.

Light Flicker

True to their name, light flickers are as disconcerting to witness as their description implies. Their presence yields several adverse consequences, contributing to subpar soft shadows and obscuring task details. Powerline frequency plays a significant role in the occurrence of light flickers, impacting the overall illumination of the classroom. It’s essential to recognize that even if low-frequency flickers go unnoticed by the naked eye, they can instigate various responses within the nervous system. Incorporating this knowledge is crucial for establishing a healthy classroom lighting system.

Direct Light and Indirect Light

A dark ceiling has the potential to create shadows when illuminated by bright lights, leading to obscured details and reduced visibility of tasks. To prevent the casting of shadows over tasks and boards within the classroom, it is advisable to avoid using dark ceilings. Conversely, students can concentrate more effectively on the blackboard without dark ceilings, particularly when discussing indirect lighting.

Object and Face Modeling

The consideration of object and facial modeling holds significant importance in discussing lighting solutions for educational facilities. The ability to read students’ lips and facilitate social communication within the classroom relies on effective facial and object modeling, emphasizing the crucial integration of light and shadow.

Moreover, lighting serves as a tool to create visually appealing interests, patterns, and highlights by introducing depth and shape to visual scenes. This enhancement is pivotal in revealing objects’ and faces’ details and information. It is essential to note that the diffused reflection of light can render faces and objects appearing uninteresting and flat. This underscores the importance of selecting appropriate directional lighting to achieve a desirable diffused lighting outlook.

Color Rendering Index (CRI)

color rendering index

The Color Rendering Index (CRI) plays a pivotal role in faithfully representing the color of an object when subjected to a light source. Notably, natural light observed during the day (i.e., daylight) boasts a CRI of 100%. Consequently, the CRI for classroom lighting should ideally be at least 80%, with a recommended level surpassing 90% for optimal color rendering.

Uniform Illuminance

When a light ray interacts with a surface, its intensity, often illuminance, is crucial. A recommended desktop illuminance for typical applications and tasks is 150 to 250 lux. Achieving uniform horizontal illuminance within the student zone is essential to minimize shadows and ensure flexibility that positively impacts task visibility.

Understanding the significance of uniform illuminance extends to the educator zone. It holds paramount importance for illuminating various planes, including vertical surfaces.

Color Appearance

Consider the impact of color, which encompasses light’s emotional, biological, and visual dimensions. You may already know how light can influence an individual’s mood. Therefore, choosing the appropriate light color is crucial to establishing a healthy, vibrant, and motivating atmosphere. Light color can have biological effects significant enough to either induce drowsiness and lethargy or promote alertness and activity.

For instance, scientific studies suggest that using blue light can aid in relaxation after a tense or highly stressful situation. Characterizing a light source involves considering two essential factors: the color rendering index and color temperature. These factors are derived from the spectral power distribution of the light source emitting the assessed light.

It’s important to note that the color appearance of non-luminous objects results from the interaction between the object’s spectral reflectance function and the light source’s spectral power distribution. Additionally, accuracy in color rendition is crucial, as the spectral power distribution of the light source influences behavior, psychological response, eye health, and satisfaction of those exposed to it.

Luminance Contrast

If you’re unaware, luminance contrast denotes the amount of light emitted by a point or light source. It is the interplay between surface reflectance and surface illuminance, illustrating that an increase in light illuminating horizontal task surfaces or any other surface leads to an increase in luminance.

This calculation is instrumental in determining the acceptable luminance contrast for chalk marks on the chalkboard. The ideal lighting reflectance for a chalkboard falls between 5% and 20%. Conversely, when considering a whiteboard, the reflectance should be at least 70% to make it a focal point of attention for all students in the classroom.

Similarly, concerning working spaces or surfaces, maintaining a reflectance level of approximately 25% to 40% ensures a comfortable and proper luminance balance. Due to their matte finishes, ceilings and walls mitigate direct glare, particularly in cool white light. They contribute to effective light inter-reflections, supporting efficient weak consumption to enhance direct light glare, vertical and horizontal illuminance, and more.

It’s essential to recognize that the human eye registers luminance, not illuminance, during visual tasks. Luminance imparts a sense and perception of brightness to the human eye. Therefore, an appealing contrast detail between the task background and its details contributes to creating visually intriguing cues for students.
