Danish mid-century diabolo pendant lamp by Lyfa, 1960s, set of 2

Two diabolo pendants from the Danish manufacturer Lyfa from the 1960s. The design is partially attributed to Jo Hammerborg, but this is not proven. A simple and symmetrical design with a classic touch in the choice of colours. The funnel-shaped umbrella slightly extends outward. It closes at the top with a small funnel that conceals the cable passage. The feature is the radial perforation made up of fine long openings, which serves to dissipate heat from the lampshade. Additionally, it diffuses light indirectly into the room through the holes.
