Working principle of metal halogen lamp

Metal halogen lamp is a new light source developed on the basis of high-pressure mercury lamp, which not only has good light color, but also has high light efficiency. Usually, some metal halides are added to the high-pressure mercury lamp, and the corresponding metal vapor is continuously provided to the arc through the circulation of the metal halides. Metal atoms are excited in the arc and radiate the characteristic spectral lines of metal. By properly selecting metal halide and controlling its proportion, metal halide lamps with different light colors can be made. These lamps contain ultraviolet light, so they need standard installation. The halogen lamp is iodine tungsten lamp. The filament iodine tungsten lamp in iodine tungsten lamp has iodine. After the chemical changes of iodine and tungsten in the filament, the temperature of the filament can be increased, so the light emitted is stronger.

Metal halide lamps have high voltage requirements and must be equipped with ballasts with corresponding specifications, otherwise the starting life will be shortened and the starting time of metal halide lamps will be long, which is not suitable for places that need rapid ignition, but iodine tungsten lamp does not have these requirements. Mainly suitable for curing UV ink and UV paint, and exposure of dry film, wet film and green solder mask. In screen printing and curing, the drying effect of coloring, especially thick coating products and black and white is outstanding.
