Holonzki Wall Lamp

Designed by Eckhard Knuth and Ingo Maurer in 2000, Holonzki is an iridescent bulb that sits perfectly on a brass socket with pull switch. The bulb is actually a holographic representation, whilst the socket and switch are real. This is a fascinating use of the hologram technique, which will baffle visitors time and again. The light source is affixed at the end of a rod and illuminates the hologram. (Please note that in some photos the rod has been airbrushed out)

The Holonzki lamp features a unique type of reflector hologram. A detailed image of the light bulb is reflected onto a section of the hologram plate. The hologram is made by a special process based on a highly sensitive emulsion which is coated onto a glass plate. The emulsion layer of the master hologram is exposed to a very short but powerful burst of light from a pulsed laser with an ultra-fast speed of nine billionths of a second. Using a laser of this type is the only means of creating an image of a small unstable component such as the filament coil in a light bulb. The master hologram is a kind of optical storage device containing all the data about the surface features of the light bulb in an encoded form that is invisible to the naked eye. The data is then etched with a continuous-beam laser into each individual Holonzki hologram. Finally, a microscopically fine relief pattern is formed in the emulsion layer by a complex chemical developing process. The pattern, interacting with the light source by absorption and reflection, creates the virtual appearance of the light bulb. Holograms of this kind cannot be mass-produced. The colours and backgrounds are never exactly identical; each hologram is made by hand and bears an individual "signature".
