Design: PH Lamp Designer: Poul Henningsen Date: 1926 Country of Origin: Denmark Manufacturer: Louis Poulsen Materials Construction: The lamps, which began production in 1926, were designed using a variety of different shapes and materials?from metal to frosted glass. Some were quite simple in form (above) while others featured incredibly complex constructions (like Henningsens iconic artichoke light). Henningsen designed PH lamps for a wide range of purposes? desk lamps, hanging pendants, and even street lights! Background: The supposed impetus for Henningsens PH lamp series was to create a light fixture that would reduce glare and cast an attractive but potent light. Using a mixture of different sized shades, his PH lamps obscured the overly bright light source and projected light evenly above the work space. Illustration by Libby VanderPloeg.
