Halogen infrared heating lamps are used in heaters:
Heating principle
Halogen infrared heating lamps are used in heaters mainly based on the principle of infrared radiation heating. There is a filament inside the halogen lamp. When current passes through the filament, the filament heats up and generates infrared rays. Halogen gas (usually iodine or bromine) is filled in the lamp tube, which can combine with tungsten atoms evaporated from the filament to form tungsten halides. Tungsten halides are decomposed by heat near the filament, and tungsten atoms are redeposited on the filament. This cycle allows the filament to work at a higher temperature, thereby emitting more infrared rays. These infrared rays propagate outward in the form of radiation, and after being absorbed by the human body and surrounding objects, they are converted into heat energy to achieve the purpose of heating.
Advantages
Efficient and fast heating: Halogen infrared heating lamps have a high energy conversion efficiency, and can convert electrical energy into infrared radiation energy in a short time, quickly raising the temperature of the surrounding environment. For example, compared with traditional electric heaters, it can make people feel noticeable warmth within a few minutes after being turned on. In some small offices or local heating scenes at home, such as in front of the desk, beside the sofa, etc., this fast heating feature is very practical.
Good directional heating effect: The infrared rays it emits have strong directionality, and the heater can achieve directional heating by adjusting the angle of the heating lamp. For example, when a person is sitting on a chair, the angle of the heating lamp of the heater can be adjusted to face the human body, so that the heat is concentrated in the area where the human body is located, reducing the heat loss to unnecessary areas around, and improving the efficiency of heating.
High safety: Halogen infrared heating lamps usually use glass lamp tubes and no exposed heating wires, which reduces the risk of burns caused by contact. Moreover, it does not produce open flames, and as long as it is used properly, it can effectively avoid fire hazards. Compared with some heating equipment that uses fuel or gas, it has great advantages in safety.
Relatively long service life: Due to the existence of halogen tungsten cycle, the loss of the filament has been delayed to a certain extent, making the service life of the heating lamp relatively long. Under normal circumstances, its service life can reach about 2000-3000 hours, reducing the trouble of frequent replacement of bulbs.
Convenient temperature adjustment: Most heaters equipped with halogen infrared heating lamps have different power levels or temperature adjustment functions. Users can easily adjust the power of the heating lamp according to actual needs, such as indoor temperature, personal preference for warmth, etc., so as to control the temperature and range of heating.
Application scenarios and precautions
Home scenarios: In the home, halogen infrared heaters can be used for local heating in different rooms such as bedrooms and living rooms. For example, it can be placed next to the sofa while watching TV, or placed next to the bed before going to bed to provide people with a comfortable warm environment. However, when using it, pay attention to keep a proper distance to avoid skin burns caused by long-term close-range exposure. It is generally recommended to keep a distance of at least 1-1.5 meters from the human body.
Commercial scenarios: Halogen infrared heaters are also popular in some small shops, offices and other places. It can be placed at cash registers, desks and other locations to provide warmth for staff. However, when used in commercial places, consider the surrounding flammable items to avoid fires caused by the heat of the heating lamp. At the same time, make sure that the heater is placed in a stable position to prevent tipping.
Industrial scene (small): Halogen infrared heaters can also be used as temporary heating equipment in local rest areas of some small industrial workshops, warehouses and other places. However, in industrial environments, attention should be paid to the complexity of the use environment. For example, dust, humidity and other conditions may affect the performance and life of the heater.
