The halogen transparent heating lamp is a highly efficient heating lamp.
Structurally, it is mainly composed of a lamp housing, a filament, and a filling gas. The lamp housing is generally made of transparent quartz glass, which is resistant to high temperatures, has good thermal stability, and allows light to penetrate well. The filament is usually a tungsten filament, which has a high melting point and can withstand high temperatures. The lamp is filled with halogen gas.
Its working principle is that after power is turned on, the filament heats and emits light. When the temperature of the filament rises, the tungsten atoms evaporate, and at this time the halogen gas reacts with the tungsten atoms to form tungsten halides. Tungsten halides decompose in the high-temperature area near the filament, and tungsten is re-deposited on the filament. This cycle prolongs the life of the filament.
The halogen transparent heating lamp has many characteristics. It heats up very quickly and can generate a lot of heat in a short time, because the energy it radiates is mainly concentrated in the infrared area, and infrared has a good thermal effect. Moreover, its temperature control is relatively precise, and the power can be adjusted as needed to control the temperature. In addition, this type of lamp has a high light efficiency and a relatively uniform light.
In terms of application scenarios, it is used in industry to dry paint and ink, such as in the printing and automotive coating industries. In the field of food processing, it is used to heat food, such as barbecue equipment in barbecue restaurants, or baking equipment in bakeries to help food heat quickly. It is also used in laboratory heating experimental devices to provide a stable heat source for various chemical experiments.
