The difference between infrared heating lamps with coating and without coating:
Reflective performance
Uncoated industrial infrared heat lamp: tungsten infrared halogen heating lamp without coating will radiate heat in all directions. Infrared rays radiate in all directions, and only a part of them can directly irradiate the target object. In some application scenarios where heat needs to be concentrated in a specific direction, the efficiency is relatively low. For example, in an open workshop, an uncoated tungsten heating element may cause the surrounding air and walls to absorb some heat, resulting in heat dispersion and failure to focus well on the work area that needs to be heated.
Coated industrial heater halogen tube: Coated tungsten heating tube are generally coated with materials with high reflectivity, such as metal coatings such as gold, silver, and aluminum. These coatings can reflect and focus infrared rays in a specific direction, greatly improving the efficiency of heat utilization. For example, in food drying equipment, by adding a coating to the tubular heating element, infrared rays can be concentrated and reflected to the surface of the food, so that the food can be dried more quickly and evenly, reducing the loss of heat to other parts of the equipment.
Energy efficiency
Uncoated tungsten infrared halogen heating lamp: Due to the dispersed direction of heat dissipation, more energy is required to achieve the same heating effect. Because a lot of heat is not effectively used, but dissipated into the surrounding environment, this leads to low overall energy efficiency. For example, in a small nursery greenhouse, an uncoated heating lamp may cause heat to dissipate to the edge and top of the greenhouse, reducing the effective heat used to heat the seedlings and requiring more electricity to maintain the temperature required for seedling growth.
Coated halogen heating bulb: Through the reflection of the coating, infrared rays can be concentrated to the area that needs to be heated, so that more energy is absorbed by the target object. In this way, when the same heating effect is achieved, the required energy input is relatively small, which improves the energy utilization efficiency. For example, in a paint room, a coated infrared heating lamp can concentrate heat and reflect it to the surface of automotive parts, speeding up the drying of the paint and reducing energy waste.
Service life
Uncoated halogen heat lamp heat element: The service life of an Transparent Infrared Heat Lamp itself mainly depends on the quality of its internal heating components such as the filament and the use environment. However, due to uneven heat dissipation, local overheating of the lamp body may occur. For example, during long-term use, the part of the lamp body shell close to the heat source may accelerate aging due to continuous high temperature, affecting the overall service life of the heating lamp.
infrared heat emitter with quartz glass with coating: A good coating can not only improve the efficiency of heat utilization, but also protect the lamp body to a certain extent. The coating can reflect part of the heat and reduce the heat absorbed by the lamp body itself, thereby reducing the risk of damage to the lamp body due to overheating. For example, the coating of the Halogen Infrared Heating Lamp Quartz Heat Tube used in the industrial heating furnace can help the lamp body maintain a relatively low temperature in a high-temperature and high-load working environment, extending the service life of the Ceramic Halogen Lamp.
Heating uniformity
transparent halogen IR lamp: When heating, the uncoated infrared halogen heating lamp radiates infrared rays in all directions, which may cause uneven heating for irregular or large objects. For example, when heating a large metal mold, the infrared intensity received by different parts is different. The part closer to the halogen heating elements will absorb more heat, while the part farther away will absorb less heat, making the overall temperature of the mold uneven.
halogen lamp replacement parts with coating: The electric infrared heat lamp with coating can make the infrared irradiate the target object more evenly by adjusting the reflection angle and position of the coating. In some occasions that require uniform heating, such as the heating link in the stretching process of plastic film, the Halogen Infaraed Heat Lamp with coating can make the infrared evenly distributed on the surface of the plastic film through reasonable reflection design, ensuring that all parts of the film can be evenly heated at the same time, improving product quality.
