Infrared (IR) lamps

描述

Infrared is widely applied in industrial heating or drying，which can be used in surface heating and drying-curing process ,such as automotive, plastics, printing, glass, textile, food, metal parts, circuit boards packaging, films and electronic neighborhood ,and can also be used in greenhouse heat preservation, and healthcare.

Infrared lamp tube, in which the tungsten wire will turn electrical energy into infrared radiation, the wavelength of which is between 780mm and 1mm, is produced on the principle of thermal radiation. The wave is a powerful radiation of thermodynamic objects, so it is also known as thermal radiation, which accelerates the drying of the printing ink. Infrared IR-A (780nm-1400nm) is typically used. Infrared lamps are usually divided into near infrared light and far infrared light.

1. Far infrared lamps are made of Milky quartz or ceramic tube. The characteristic is fast heating up, uniform heating, good penetration, small thermal inertia. It just needs 1-3 minutes to reach the component temperature, and the high power radiation conversion efficiency reaches 60%-75%. It will not crack in hot or cold condition, with the features of energy saving and long service life.
2. Near infrared lamps IR-A （780-1400nm，1400-3000nm）, the characteristic of which is fast heating up, high efficiency, and the convenient control in the heating process, such lamp tubes are divided into single-pipe form, double pipe form and straight pipe form.

To improve thermal efficiency and save energy, the different angles of the single and double -pipe infrared lamp can be coated with high performance and durable gold-coated reflective layer to achieve above 96% emission efficiency and extend the service life of the lamp.

Gold-coated reflective layer can considerably lower the temperature of non-heating in the reverse side, reducing the high temperature of equipment and furnace body and saving the reflector. Gold-plated or ceramic–plated reflective layer can concentrate heat in the heating direction to improve the heat efficiency and save electric energy.

It is recommended to use gold-plated layer when the lamp surface temperature is lower than 800 ℃. When the temperature is higher than 800 ℃, it is recommended to use ceramic-plated reflection layer, which can resist 1000 ℃.

Except the standard plated layer of 180 degrees (semi-circle), the plated layer of 270 degrees (3/4 circle) and other angles can be produced according to the users requirements.
