Challenge the norm – dare to use more light

Lighting is essential for visual tasks and helps maintain attention levels. By using luminaires that combine direct light on the work surfaces with an indirect light aimed towards the ceiling, a varying and appropriate concentration of light is distributed throughout the room.

This solution for classrooms is among the best – and is still an excellent choice. The room has a well-balanced combination of direct light at the work surface and ambient light against the walls and ceiling. The pendant luminaires efficiently distributes the light without glare.

To get high enough light levels, several luminaires in a row is recommended in the classroom. By having several daylight sensors, we can ensure that all students in the room gets enough light – while at the same time reducing energy consumption. To facilitate the teachers work the board is equipped with a separate lighting and the room can be equipped with pre programmed light scenarios.

If you wish a ceiling with a cleaner look you can work with a recessed solution. Worth thinking about is that you should move out of the fixtures further out towards the walls to get more light on the walls. Even in this solution, it is important to supply board lighting without glare.

A recessed solution should also have installed lighting controls, such as an e-Sense solution to control the various rows of luminaire separately and also create different lighting scenes for different applications or AV light. Just as in all work areas a fitting without glare is recommended.

Tips

The standard EN 12464-1 now sets requirements in terms of lighting of ceilings and walls. At Fagerhult we believe this is a step in the right direction. But if you want to get the full benefit of light’s positive effects, you need more light than what the legislation requires.

Higher levels of ambient light increase alertness and improve performance

Lighting is essential for visual tasks and helps maintain attention levels. Few pupils spend their day staring down at the desk; frequent interaction with the teacher, fellow students and the teaching surface (whiteboard, chalkboard or interactive screen) mean that their gaze is moving around the room and their focus constantly changing. Often the contrasts between the lighting of the work surfaces, walls and the ceiling tire or strain the eye.

More light on ceiling and walls

By using luminaires that combine direct light on the work surfaces with an indirect light aimed towards the ceiling, a varying and appropriate concentration of light is distributed throughout the room. Vertical light on the wall, 300 lx, provides good ambient light. Indirect light on the ceiling, 300 lx, also provides good ambient light and students who are more alert and perform better.

Light on the work surface

Direct light from the luminaires always gives 500 lx on the table, to make the visual task easier. For reading, uniformity of light is important whereas practical and intricate tasks require high levels of light.

Lighting of the whiteboard

To ensure what is written or displayed on the whiteboard is easy to read, the standard requires a minimum illuminance of 500 lux. The lighting shall be adjustable.

Cylindrical illuminance (in rooms with demands of good visual communication)

Cylindrical illuminance especially affects visual communication and the ability to interpret faces, events and objects. The standard requires a minimum illuminance of 150 lx in rooms with demands of good visual communication.

Adjust lighting after task

The colour rendering properties of the light source are significant when working with design and colour. The colour rendering in general should be at least Ra 80, although for photography this value may need to rise to Ra 90.

Avoid glare

The luminaires must be suitable for work at monitors, and avoid glare and veiling reflections. Young people need less light than older people in order to perform the same tasks. As we age, our sensitivity to glare also increases, therefore more light may be needed for adult education classrooms.

Light control

Fagerhult’s wireless e-Sense Connect lighting control system has been developed for professional installation in educational establishments. The installation and user functions focus on simplicity.

A daylight and presence detector in every row of luminaires adjusts the lighting for all areas of the space. When everyone has left the room, the light switches off and is reset automatically.
