Primula was born of designer Knud Holscher's vision of creating an outdoor lighting series based on effective, non-glaring illumination that optimises the light from its source. Primula does this through a combination of optical elements that also utilises stray light. A lighted Primula has a unique identity, as the white rings appear to be suspended in air. Primula is also available as bollards in 50 and 80 cm and as a wall fixture.
All versions are available with a low voltage halogen light source or a metal halide light source.
Design by Knud Holscher
Knud Holscher developed the principles behind Primula in collaboration with the engineering firm, Hansen & Henneberg. The basic component is a symmetrical reflector that transmits light from the source directly to the top reflector, which ensures an effective distribution. The other optical element is white reflecting rings which utilise the light that does not hit the reflector. The stray light is collected and used by the white rings without affecting the lamp's efficiency, which is 49%. Two bottom reflectors send a minor luminous flux through the bottom of the armature housing and illuminate the posle and its base.
