Fragrance lamp

A lamp Berger, also referred to as catalytic lamp, is a lamp aroma which evaporates the perfume by means of a porous ceramic head, which has been previously heated by the combustion.

History

Developed Lampe Berger of the French pharmacist Maurice Berger end of the 19th century. He let his further development of the French lamp Müller in June 1898 patent as Lampe Berger. 1927, the rights to the industrialist Jean -Jacques Failliot were sold, which could increase the sales of the lamps annually to 20,000 units through targeted advertising campaigns after a short time. Aroma lamps were designed, among other things by Gallé, René Lalique, Saint- Louis and Baccarat. During the Second World War, production was due to the lack of raw materials and the partial destruction of the factories in 1943 sharply. Currently about 15,000 lamps are made daily.

Principle

During a firing time of 2 minutes, the ceramic of the lamp head is heated by an open flame to about 300 degrees Celsius. Following the open flame is blown out carefully. Through the heated ceramic head evaporate aroma -containing isopropanol and the smell diffused through the room air. At the same time it is initially up to 500 degrees Celsius for a short time to the edge of a catalytic oxidation of molecules in the air. As long as oxygen in the ambient air is available, takes place in the ceramic head catalyzed oxidation of isopropanol, maintaining the temperature of the head at about 80 degrees Celsius. At this temperature, parallel runs the evaporation of perfume -isopropanol mixture. The oxidation of the isopropanol is completed by placing a cap.

Criticism

Advocates and distributors of these lamps is argued that these lamps produce ozone and anions and is supposed to free spaces of bacteria. A study conducted by the Environmental Protection Agency study has found that ozone in non-hazardous concentrations had no detectable effect on the existing materials in the room. In addition, the name of lamp is misleading, since the emissions are not due to the temperature in the visible region of the electromagnetic spectrum. This can pose a significant risk of injury, because the very hot decoration object can not be seen as a source of danger, so occasionally an additional attachment to protect from severe burns is placed after combustion.
