As a highly efficient and clean heat source, it is used in the drying process of liquid crystal panels and in the deposition process of semiconductors, etc.

Features

Long life time

As the temperature of a general heat-generating bulb rises, tungsten evaporates from the filament and attaches to the inner wall of the bulb, causing anode spot, resulting in a decrease in light intensity and thinning of the filament, leading to wire breakage (filament life).
Halogen lamps prevent this anode spot by adding 0.1-0.6% halogen compound gas to inert gas (nitrogen, argon, krypton, etc.), which generates a halogen cycle.

Small, compact, clean

・Use of a quartz tube with high heat resistance for the bulb results in a compact, high-efficiency bulb
・The use of quartz tubes prevents metal contamination and keeps the object to be heated clean

High-efficiency

・The use of tungsten as a heating element allows the lamp to reach its maximum output in a few seconds.
・The heat conversion efficiency of halogen lamps is that about 80% of the input energy is converted into infrared rays (heat rays), so it is widely used for heating purposes.
・The temperature can be set according to the object to be heated, resulting in higher thermal efficiency and shorter heat-up time compared to other heaters.
