PH-lamp
The PH-lamps are a series of light fixtures designed by Danish designer and writer Poul Henningsen from 1926 onwards. The lamp is designed with multiple concentric shades to eliminate visual glare, only emitting reflected light, obscuring the light source. Henningsen's sleek, spare lamp was awarded a gold medal at the 1925 International Exhibition of Modern Decorative and Industrial Arts. The lamps are still in production today.
