A halogen lamp is a type of incandescent lamp that contains trace amounts of halogen elements (iodine, bromine, etc.) in addition to inert gases such as nitrogen and argon.
Halogen lamps emit light in the same way as ordinary incandescent lamps, by passing electricity through a filament inside the bulb. The filament is a thin, thread-like metal wire, most often made of tungsten, which has the highest melting point of all metals (3,422°C).
Halogen lamps are used for spotlighting on product shelves, floodlighting, car headlights, studio and stage lighting, and other applications because of their compact size, high luminance, easily adjustable light distribution (light spread), and good color rendering properties (colors are close to those seen in sunlight). However, with the spread of LED light sources, opportunities for use in lighting applications are decreasing.
Halogen lamps have been used as light sources for OHPs and slide projectors used in schools, etc. Today, LED and laser light sources are becoming the mainstream.
Light sources for spectroscopic analysis are used because they have a constant brightness over a wide range of wavelengths and little fluctuation in intensity over time.
The fact that the majority of the energy radiated is infrared tells us that halogen lamps as light sources are inefficient but excellent heaters. Therefore, halogen lamps have applications in a variety of situations requiring localized heating, such as heat retention, heat treatment, drying, and high-temperature molding of food and materials, in addition to localized heating indoors and outdoors.
The filament temperature of ordinary incandescent lamps ranges from 1,500 to 3,000°C, while that of halogen lamps is usually as high as 2,500 to 3,000°C, with special ones reaching as high as 3,300°C. Therefore, a small amount of tungsten is constantly evaporating on the surface of the filament.
Figure 1. Halogen Cycle
To suppress the blackening phenomenon, halogen lamps contain a small amount of halogen elements along with inert gas in the bulb. In this way, if conditions such as temperature and materials are appropriate, the blackening phenomenon will not occur due to the halogen cycle that occurs in the lamp.
The halogen cycle is a phenomenon that occurs in the following manner.
The halogen cycle prevents filament wear and tungsten-induced blackening of the glass inner wall.
Figure 2. Incandescent and Halogen Lamps
To achieve a halogen cycle, the encapsulated glass must be kept at a high temperature. When iodine is used as a halogen gas, the glass temperature must be 170°C or higher, and when bromine is used, the glass temperature must be 250°C or higher.
Therefore, quartz glass, which can withstand high temperatures, is usually used, and molybdenum foil is used to electrically connect the inside and outside of the halogen bulb so that the inside remains airtight even at high temperatures.
In ordinary incandescent bulbs, blackening occurs when evaporated tungsten adheres to the inner wall of the bulb's glass. As the filament wears out, the luminous efficiency inevitably decreases.
This blackening phenomenon is an obstacle, making it difficult to miniaturize incandescent bulbs with high power consumption or to raise the filament temperature to higher levels to increase brightness and color temperature.
Figure 3. Filament Temperature and Intensity Distribution of Emission Spectrum
The light spectrum emitted from a halogen lamp is almost identical to the blackbody radiation spectrum, which corresponds to the temperature of the filament. Because the temperature of the filament is lower than that of the sun, the emitted light contains almost no ultraviolet light, and its visible light portion has a slightly higher red component, resulting in a warm white light appearance.
The peak of the radiation is in the near-infrared region with wavelengths of 900 to 1,000 nm, and the majority of the radiation is in the visible to near-infrared region with wavelengths of 500 to 3,000 nm.
Compared to ordinary incandescent lamps, halogen lamps allow a smaller distance between the filament and the encapsulated glass. Also, the temperature of the filament can be higher, which offers various advantages.
