2500w 840mm half gold coated infrared halogen heat lamps

The heating principle of the halogen semi-gold-plated heating tube is mainly based on the following aspects:
Current thermal effect: There is a tungsten wire in the halogen semi-gold-plated heating tube. When the current passes through the tungsten wire, the tungsten wire has a certain resistance. According to Joule’s law, the current passing through the conductor will generate heat, causing the tungsten wire to heat up. The resistance of the tungsten wire is relatively large, and it can effectively convert electrical energy into thermal energy, thereby generating a large amount of heat.
Halogen cycle effect: The heating tube is filled with inert gas of halogen elements, such as iodine vapor. During the heating process, the tungsten wire will gradually sublimate to produce tungsten atoms, and the halogen element gas will react chemically with the tungsten atoms to form tungsten halides. Tungsten halides will decompose at high temperatures, causing tungsten atoms to return to the surface of the tungsten wire. This halogen tungsten cycle effectively reduces the volatilization and loss of the tungsten wire, prolongs the service life of the heating tube, and also ensures the stability and efficiency of the heating process.
Infrared radiation heat transfer: The heated tungsten wire will increase the temperature of the gas in the quartz glass tube, thereby generating infrared radiation. Infrared is an electromagnetic wave with strong penetration ability and thermal effect. The semi-gold-plated design mainly coats the surface of the heating tube with a layer of gold film, which can enhance the reflection effect of the heating tube on infrared rays, so that more infrared rays can be radiated in a direction, improve the heating efficiency and energy utilization, and then heat the surrounding objects.
