!±8± Ph 4 3 Pendant Light
Louis Paulsen, ph 4 3 pendant light PH 4/3 Pendant is a member of the PH 3-shade family, and the principle behind the PH 3-shade fixture was made in a few hectic months in the winter of 1925-26 for a large exhibition hall in Copenhagen, Denmark called ?Forum?. This is what PH said about his new fixture in 1926: ?The real innovation in the PH-fixture is that it produces lighting which is both glare free and economical. It is easy enough to create glare-free light (indirect and strongly shaded light) if a portion of the light is allowed to be wasted, and it is equally easy to make fixtures which are highly efficient if you ignore the fact that they severely irritate the eye (strong specular reflection, etc.) but it is an art to make light both economical and glare free.? Before the development of the 3-shade fixture, Poul Henningsen and Louis Poulsen had been working together on designing the fixtures for the Danish Pavilion at the World Expo in Paris, France in 1925. When Poul Henningsen designed the fixtures for the World Expo, he had already been playing with the idea that the logarithmic spiral was perhaps a suitable basis for a new shade structure. The combination of diffused reflection and a logarithmic shade curve also gave PH the opportunity to control the fixture?s glare and shading, as each shade would evenly decrease the amount of light emitted according to their distance from the bulb. The luminance transitions from shade to shade would also appear harmonic. The relative size of the shades and their positioning was determined by the need to reduce glare - the light disposition on the shades and the light distribution demands - according to some remarkably simple principles. From the beginning it was obvious that the concept was extremely flexible. Not only was it possible to get it in many different sizes, but also with different undersides - either a White painted surface, a Silver-Plated or Gold-Plated surface. These different undersides were i
