“I finalized the design of Plain in 2014, but I’d had the concept in mind for a long while.” So says Tommy Govén, the designer behind the recessed luminaire series, Plain. The idea behind the concept was to develop a luminaire that can provide conditions for evenly

distributed, glare-free surface illumination efficiently. The latest research into lighting has shown that surface illumination, i.e. lighting on a room’s ceiling and walls, has a significant impact on a person’s circadian rhythm, well-being and performance.

Because the focus was on the luminaire’s technical characteristics, Govén wanted to create a luminaire that did not take up space in the room’s architecture, but disappeared visually into the surface of the ceiling or wall. Accordingly, the luminaire’s visible parts are

white and the optical parts hidden. LEDs were the natural choice to create an energy-efficient, compact luminaire with good optical characteristics while allowing simple control of the light
