Lighting laboratory
Light is important to all living things – not least to human life – though it is not necessarily something we think much about. Eye sight is the sense that is used the most and takes in the most impressions and thus also affects us to a great extent. Visual impressions are closely linked to well-being, health and the circadian rhythm, and research on light and darkness is therefore particularly important for good health.
The lighting laboratory at the faculty of engineering (LTH) is built to enable studies on how humans are affected by different light conditions such as glare and flicker. The lab also has equipment to study in detail the spectrum, color reproduction, color temperature, luminance, flicker and electricity of light sources such as lamps and luminaires.
Equipment in the laboratory
The lighting laboratory is equipped with several important measuring instruments. Some of them are:
- spectrometer
- light meter
- luminance camera
- flicker meter
- measuring equipment for electricity quality
Large parts of the equipment are portable to be used in field studies, in research projects and at the request of companies and organizations.
Who can use the lighting laboratory?
The Lighting laboratory is used by students and researchers as well as external actors interested in light and illumination.
Some examples of measurements performed in the lab are streetlamp luminance, flicker in lamps, verification of light and colour specifications of a light source as well as assessment of glare and flicker at a workplace.
