The working principle of the halogen double tube semi gold plated infrared heating lamp is to stimulate the halogen gas inside the lamp bead through electric energy to produce high-temperature and high-pressure ionized gas, that is, plasma, thereby emitting infrared rays to achieve the functions of heating and drying.
Its working process is as follows:
Current passes through the filament: When the current passes through the filament, the filament will heat up and heat up.
Excite the halogen gas: The high temperature of the filament will excite the halogen gas in the lamp tube, ionizing it to form plasma.
Emit infrared rays: The electrons in the plasma will release energy when they return to the ground state, and this energy is radiated in the form of infrared rays.
Semi-gold-plated layer reflection: The semi gold plated layer on the inner wall of the lamp tube can reflect infrared rays, so that it can be concentrated in one direction and radiate, thereby improving the heating efficiency.
Heating objects: When infrared rays are irradiated on an object, they will be absorbed by the object and converted into heat energy, thereby increasing the temperature of the object.
Factors affecting the service life of the halogen double tube semi gold plated infrared heating elements:
Filament quality: The filament is the core component of the quartz halogen infrared heat lamp. The filament of a ir quartz element is generally a tungsten filament, which works at high temperatures. High-quality tungsten filaments can withstand higher temperatures and longer use. If the tungsten filament is of high purity and fine craftsmanship, it can better resist sublimation and melting at high temperatures, thereby extending its service life. For example, a tungsten filament with a purity of 99.99% may have a service life that is 20-30% longer than a tungsten filament with a lower purity under the same working conditions.
Working temperature: Halogen double tube semi gold plated Ir Heating Element are very hot when working. Generally speaking, the higher the working temperature, the faster the filament wears out. This is because high temperature accelerates the sublimation process of the tungsten filament, causing tungsten atoms to escape from the surface of the filament. As the use time increases, the filament will gradually become thinner and eventually cause melting. For example, when the operating temperature exceeds the design temperature by 10%, the service life may be shortened by 30-50%.
Use environment:
Ambient temperature: If the ambient temperature around the lamp is too high, it will affect the heat dissipation of the lamp, causing the internal temperature of the Halogen Bulbs to rise, thereby shortening the service life of the filament. On the contrary, at a lower ambient temperature, the heat dissipation of the lamp is better, which is conducive to extending the service life. For example, if the lamp is used in an environment with a temperature of 40°C, the service life may be shortened by 15-20% compared to that in an environment with a temperature of 20°C.
Air humidity and corrosive gases: A high humidity environment may cause the internal parts of the lamp to rust or corrode. If there are corrosive gases such as sulfur dioxide and hydrogen chloride around, it will damage the filament and other parts of the lamp. For example, if the high temperature resistance quartz glass tube lamp is used in an environment polluted by chemical waste gas, the service life of the lamp may be shortened by more than 50% compared to that in a clean environment.
Switching frequency: Frequent switching of replacement infrared halogen lamp will also affect their service life. Every time the Shortwave Infrared Heating Element is turned on, the cold resistance of the filament is small. At the moment of power on, a large current will pass through, generating a large thermal shock, which will accelerate the damage of the filament. For example, the service life of a lamp that is frequently switched on and off (more than 10 times a day) may be shortened by 30-40% compared to a halogen ir heat lamp that is used normally (no more than 3 times a day).
General service life range
Under normal use conditions, that is, the working temperature is suitable, the environment is good (temperature is 15-30℃, humidity is 40-60%, no corrosive gas), and the switching frequency is low (no more than 3 times a day), the service life of the halogen double tube semi gold plated tungsten halogen lamp is generally around 3000-5000 hours. However, this is only a rough range, and the actual service life will be affected by the combined influence of the above factors. If you pay attention to maintenance during use, such as maintaining a good heat dissipation environment and avoiding frequent switching, the service life may be close to or exceed 5000 hours; on the contrary, if used under harsh conditions, such as high temperature and high humidity environment or frequent switching, the service life may be less than 3000 hours.
