The role of the gold plated layer in infrared heating lamps:
Reflecting infrared rays and improving heating efficiency
The main role of the gold plated layer in halogen heating bulbs is to reflect halogen heating lamp. Gold is a material with a high reflectivity for infrared rays. In IR emmiter, the gold-plated layer can effectively reflect the halogen heating lamp generated inside the ir lamp halogen heating lamp. When infrared rays are emitted from heat sources such as filaments, if some of the Infrared quartz heater replacement lamp are not reflected, they will be lost inside the lamp tube or absorbed by the lamp tube itself, which will reduce the heating efficiency. The gold-plated layer can reflect these IR Lamp Infrared Heat Lamp to the heated object, so that more infrared rays can act on the heated object, thereby improving the heating efficiency. For example, in a comparative experiment between an infrared heating lamp using a gold-plated layer and a heating lamp without a gold-plated layer, it was found that the heating lamp with a gold-plated layer heated the same object about 30% – 50% faster than the heating lamp without a gold-plated layer.
Enhance the directivity of thermal radiation
The gold-plated layer helps to enhance the directivity of thermal radiation. By reflecting infrared rays, the gold plated layer can make the infrared rays radiate more concentratedly in a specific direction. This is very important in situations where specific areas or objects need to be precisely heated. For example, in industrial production, when local heating and welding of electronic components or drying of a certain part of a precision instrument, the heat radiation needs to have good directionality. The gold plated layer can focus the infrared rays to the area that needs to be heated, reduce the impact on the surrounding areas that do not need to be heated, and improve the accuracy of heating.
Protect the lamp and extend the service life
The gold plated layer can also play a certain role in protecting the quartz electric heating lamp. During the heating process, high temperature will be generated inside the lamp, and the infrared radiation may also cause certain damage to the Quartz Infrared Heating Elements. The gold plated layer can block the direct effect of Quartz IR Halogen Heating Bulb on the Quartz Heater Bulb to a certain extent, and reduce the aging and damage of the material caused by long-term infrared radiation. At the same time, the gold-plated layer can reflect heat and help the heat dissipation of the lamp. For example, in some quartz tungsten halogen heat lamps used in high-temperature environments, the service life of the lamp with a gold-plated layer may be extended by 20% – 30% compared with the tungsten infrared heat lamp without a gold-plated layer.
Aesthetics and identification
From the appearance, the golden gold plated layer makes the Quartz Infrared Halogen Heating Elements look more beautiful. In some occasions where the appearance of the equipment is required, such as in display-type industrial equipment or high end home heating equipment, the gold plating layer can enhance the overall texture of the equipment. In addition, the gold plating layer can also be used as a logo to indicate that the IR Quartz Heating Elements has good performance or belongs to a high-end product series.
