The Arco lamp is a modern floor lamp designed by brothers Pier Giacomo and Achille Castiglioni for Flos in 1962. [1] The lamp is characterized by a suspended spun aluminum pendant attached to an upright block of Carrara marble via a cantilevered arching arm made of stainless steel.
A mercury arc lamp from a fluorescence microscope. A krypton long arc lamp (top) is shown above a xenon flashtube. The two lamps, used for laser pumping, are very different in the shape of the electrodes, in particular, the cathode (on the left). An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc).
The arc then continues to burn, gradually consuming the carbon electrodes and the intervening plaster, which melts at the same pace. The first candles were powered by a Gramme machine . The drawback of using direct current was that one of the rods would burn at twice the rate of the other.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.
These arc lamps ran on relatively low voltages and incorporated tungsten filaments to start ionization within the envelope. They provided the intense concentrated light of an arc lamp but were easier to operate. Developed around 1915, these lamps were displaced by mercury and xenon arc lamps. [128] [129] [130]
