PH 3/2 wall lamp

PH 3/2 wall lamp from Louis Poulsen features shades made of reflective mouth-blown opal glass in three layers that direct most of the light downwards. They are glossy on the outside and have a matte, sandblasted inside that provides a soft and diffuse light. The iconic three-shade system was designed by Danish Poul Henningsen, who in collaboration with Louis Poulsen designed the first PH lamps in 1925-1926 for an exhibition in Paris. Here, he has used a scientific perspective as the lamp is constructed based on the logarithmic spiral, a mathematical spiral curve that occurs in many places in nature. This provides an even distribution over the entire curve of the shade, and together with the diffuse reflection through the glass, a harmonious and glare-free light is created. The numbers in the PH lamps' names refer to the size of the shades, and the letters come from the designer's initials. Feel free to explore the wide range of PH lamps.
