What is a halogen lamp

Tungsten halogen lamp, as the name implies, the filling gas inside the bulb is a gas-filled incandescent lamp that contains some halogen elements or halides. Under appropriate high temperature conditions, the high temperature of the filament will cause the tungsten filament to evaporate, and the tungsten evaporated from the filament will react with the halogen in the inner wall area of the bulb to form a functional halogen tungsten compound.

Halogen lamps are also called quartz bulbs, and halogen lamps are also one of the types of incandescent lamps. It's just that in the process of making the halogen lamp, some halogen gas such as bromine or iodine is added to the bulb. When under the appropriate high temperature, the tungsten filament sublimation will have a corresponding chemical reaction with the halogen element in the halogen bulb, and the sublimated tungsten will recondensate on the tungsten filament, forming a cycle, avoiding the tungsten filament from breaking prematurely. It is also because the life span of halogen lamps is longer than that of incandescent lamps.

What are the advantages and disadvantages of tungsten halogen lamps

1. Tungsten halogen lamp is a new product emerging from the third generation of lamps. A halogen lamp is a gas filled incandescent lamp with some halogen elements or halides in the filling gas. In ordinary incandescent lamps, the high temperature of the filament causes the evaporation of tungsten, and the evaporated tungsten precipitates on the glass bulb, causing the bulb glass bulb to turn black. In 1959, the tungsten halogen lamp was invented, and the blackening phenomenon was eliminated by the principle of tungsten halogen cycle.

2. The halogen tungsten lamp has the advantages of small size, luminous effect, stable color temperature, almost no light decay, and long life. Its working temperature is relatively high, and it is not suitable for places with dusty, flammable, explosive, corrosive environment, and places with vibration. If you get hands or oil stains, the quartz glass will lose its luster, turn into a white turbid color, reduce the brightness, shorten the life span, or even break the glass shell.


What is the difference between halogen lamp and halogen lamp

1. The most attractive part of the halogen lamp is that it can make the surface color of the object more vivid, and can bring out a charming flashing effect. Because the size of the lamp is very small and exquisite and the variety and specifications are complete, there are many angles from narrow to wide to choose from, which provides a lot of creative space for professional lighting design. From an economic point of view, halogen lamps are particularly "bright". For example, incandescent lamps need to consume 75W of electrical energy to achieve a luminous flux of 960 lumens, while halogen lamps only need about 50W.

2. The tungsten halogen lamp is named after the bulb is filled with metal halides. The basic structure and light-emitting principle are roughly similar to fluorescent tubes. The difference is that arc discharge lighting produces high heat. The metal halide sublimates into vapor and directly emits visible light. Energy-saving 80% to 90%, belongs to the third generation of lighting source.

3. Tungsten halogen lamps are the third-generation green lighting sources that have emerged after incandescent lamps and halogen lamps. With high luminous efficiency, good color rendering, and long service life, they have not only become the choice of light sources for cars, rear-projection TVs, etc. It can also be widely used in military, expedition, underwater operations, field search and rescue and other fields.
