The PH 3½-3 Glass Sospensione lamp represents one of the many innovative projects undertaken in 1926 by Poul Henningsen to develop his world-famous three-shade system. Poul Henningsen dedicated much of his life to studying electric light. Its three-screen design, based on the litho, or logarithmic spiral, was intended to optimize the use of the light source. His studies are the result of numerous calculations and tests. The shape of the screens is linked to the way the light was to be shaped and reflected. Furthermore, the lamp has been designed to diffuse glare-free lighting. The opal white glass screens soften the overall appearance of the lamp and illuminate the surrounding area with that perfect, harmonious and anti-glare light that only the classic three-screen system is able to offer. The screens are made of three-layer opaline glass, polished on the upper surface and sandblasted and satin-finished on the lower surface, to create a soft and uniform light distribution.
System of lighting
The luminaire was designed according to the principle of three reflective screens which direct most of the light downwards. The screens are made of three-layer blown opaline glass, polished on the top and sandblasted to a satin finish on the bottom and offer a soft and uniform light distribution.
Materials and finishing
Materials Screens: blown white opaline glass. Suspension: shiny chromed or metallic black pulled brass or metallic brass.
Finish: Metallic brass, metallic black or shiny chrome. Opaline white glass.
