The special-shaped infrared heating pipe belongs to the thermal radiation light source. The lamp has the advantages of convenient installation, no need for any accessories, and can be used in AC and DC circuits. It is mainly used for industrial heating or drying, such as circuit board butting, all kinds of baking varnish, film and heating. Clean, hygienic, temperature controllable, can be dried under normal pressure, heating, can also work in vacuum, can be used horizontally, can also be vertical heating of special equipment, can produce different color temperature near, far infrared, in the lamp spectrum, can be different shapes of tungsten wire heating light source. For example: triangle filament, connecting filament (connecting filament and bracket are integrated), intermittent filament and some other materials heating light source. Using transparent or translucent, frosted or opalescent, quartz glass as lamp shell, can produce near and far infrared radiation lines. And can design and produce different lengths, different color temperature, different shapes of single-hole and double-hole infrared lamp.
