The idea of reflecting daylight is old and has been practiced for thousands of years. Nowadays, combined with new materials and technology, this old technique can help people to save energy and to improve the light quality of interior spaces.

The lamp Daylight is a part of a system that consists of reflecting lamellae (plates) mounted on the facade of a building and reflecting devices in the room. The aim of the system is to reflect daylight, not direct sunlight. Daylight is streamed indoors by the external reflecting plates, and re-reflected internally by the interior reflecting devices. The reflecting plates can be adjusted individually.

The reflecting surfaces are made of 0.4mm special reflective aluminium, which has a reflection factor of 98%. A typical mirror at home reflects around 75–86% of light. A special pattern on the surfaces spreads the light.

Modern LEDs illuminate the room during the hours when there is not enough daylight to reflect. A light sensor calculates how much artificial light needs to be added to achieve a certain light level. Also, the colour of daylight (which changes during the day) can be simulated. Manual adjustments can be made by the user.

Most of the parts are made with aluminium and can be recycled. The injection-moulded side parts have been designed for production using just two tool parts. All aluminium parts except the reflector surface are powder coated. During the recycling process, the powder coating can be separated from the aluminium and, after that, also used for the creation of new coating.

In terms of design form, the lamp was given a technical appearance but also complements nature in the look of the surfaces. The aim was to call to mind the structure of tropical leaves.
