Piet Hein's 1969 Ra-Lamp for Hyfa

Piet Hein, the Dane who has achieved world renown as a theorist, inventor and poet, has created a new lamp for Lyfa A/S. Piet Hein calls his lamp the Ra lamp, after the ancient Egyptian sun god. The Ra lamp has been introduced both in Denmark and in the international market, and is based on a new Piet Hein discovery – isoluxfladerne – which basically is a way of providing as much regular light as possible without dazzle.
