In the spring of 2022, Louis Poulsen will reissue <PH 3/3 pendant≫ and ≪PH 5/5 pendant≫ in addition to the ≪PH lamp series≪≫ by designer Poul Henningsen> The "prototype model" PH pendant is a lighting fixture with a three-shade system designed to be hung high on the ceiling, and the space is
In 1926, Poul Henningsen designed the PH3/1 table lamp, which emits glare-free, glare-free light based on the three-shade system*1931 developed in 2. The light emitted from the shade illuminates the table surface most brightly, diffusing a pleasant light. Handmade glass is used to create an ideal and soft atmosphere, and although it is classic, it is recognizable as a "PH lamp" at a glance. Henningsen also designed not just lamps, but comprehensive lighting systems, which in his lifetime produced 2 different models. These include wall lamps, table lamps, floor lamps, as well as chandeliers that became popular in the 100s for high-ceilinged homes. There were also a lot of combinations and options. There was also a wide variety of colors and sizes. Early shades were made of metal, painted in white, gold, silver, etc., and the finish was chosen according to the place of use, such as diffused, warm, or cool light. Later, glass was added to the three-piece shade system. Hennningsen was the first to adopt a scientific approach to the design of lighting fixtures and to use logarithmic spirals for the curves of shades. By using a design based on logarithmic spirals, they were able to achieve a gentle light distribution across the curved surface of the shade. This gentle light distribution, combined with the diffused light reflected by the inner surface of the shade, allows for glare and shadow control. The amount of light reflected by each shade decreases evenly as the distance to the light source increases.
The mathematical naming of the lamp derives from Henningsen's rational work with the system PH. The system allows you to combine shade sizes, materials, and surfaces all to create optimal lighting for a specific task. This designation indicates the number of fractions based on the diameter-size ratio of the upper shade. When the top shade is combined with the middle shade, lower shade and bottom bowl, where the lamp was originally developed in a 3:2:1 ratio, the result is a "prototype model" such as ≪PH 3/3≫ and ≪PH 5/5≫.
The model number of the PH lamp indicates the size of the shade. A "prototype model≫ such as ≪PH 3/3 has a top shade with a diameter of about 30 cm and a corresponding middle and bottom shade. The shade ratio is approximately 3:2:1, which gives it a rounder and compact appearance compared to hybrid sizes such as PH 2/1.
The shades of ≪PH 3/3≫ and ≪PH 5/5≫ are a combination of milky white glass shades or metal shades (black matte paint on the outside and white matte paint on the inside), respectively. The milky white glass shade is a three-layer structure with shiny transparent glass on the outer and inner layers and a milky white glass layer sandwiched in the middle. In addition, the inside of the shade, which receives light directly from the bulb, is sandblasted to form a matte that reflects and evenly diffuses soft light that is pleasing to the eye.
≪PH 3/3≫ and ≪PH 5/5≫ will be available in the spring of 2022.
