The A331 ceiling lamp, also known as the Beehive, is a design classic by Alvar Aalto and was first introduced in the interior design of the University of Jyväskylä, in Finland. Most of Aalto’s lamps are part of a larger architectural plan and there is a clear reference to this characteristic in the aesthetic of Beehive. The lamp is decorative and sculptural even when unlit and has a structure that allows the light to be diffused through the brass elements that join the aluminium sheets. Thanks to the brass elements, the light gets just the right shade of warmth. It was very important for Aalto that the lamp’s light emitted a warm glow and that’s why he used polished brass in the design.
