Light to Support Students Through the Night | Lighting Environments Conducive to Study and Eye Care

Exam season. For students who study late into the night, light on their desk is an everyday necessity.

While studying is ultimately up to the individual, providing an environment with light that facilitates study can be a supportive measure.

Brightness and Color Temperature for Studying

According to JIS illuminance standards (JIS Z 9110), approximately 500 lux is recommended for studying and reading. If the area around the hands is dark, the eyes tend to strain, so sufficient brightness suitable for the task is crucial. A neutral white color (around 4000K), which is neither too bright nor too subdued, is considered suitable for studying.

Key Points for Eye Comfort

• Reduce the contrast between the desk and surroundings: If only the desk is bright and the room is dark, eyes tend to strain. Keep the entire room moderately lit.
• Consider glare and flicker: Look for uniformly diffused light and flicker-free design.
• High color rendering: Makes text and diagrams easy to see.

After Studying Late at Night, Dim the Lights

Students often stay up late. After studying, dim the lights before going to bed to help create an environment conducive to sleep. For more on color temperature, please refer to What is Color Temperature?.

In the case of lipro

The Sunlight Ceiling Light offers a "Study Mode" with a white light of 4000K, suitable for studying. With a color rendering index of Ra97+, brightness adjustment from 0-100%, uniform diffusion, and flicker-free design, it can create an optimally bright environment for studying throughout the entire room.

Summary | Support Late-Night Studying with Suitable Light

Supporting students' late-night studies involves appropriate brightness and light that considers eye strain. While the ease of studying depends on the individual, families can subtly provide support by optimizing the lighting environment.
