In order to replace conventional bulbs, they created an analog with high brightness, requiring a lower voltage in the network, suitable for standard socles. Halogen lamps differ from standard industrial fixtures, home chandeliers in terms of luminous flux and durability. They have found application in the manufacture of automotive headlights with high brightness, lighting devices operating from low voltage and having compact dimensions. You can order by mail or buy halogen lamps in any store – the goods are in demand.

What is a halogen lamp?

This is a special device for lighting rooms, working on the same principle as standard power fixtures. Halogen bulbs consist of a cap, an incandescent filament, a sealed bulb filled with gas. Atoms of a gaseous active substance react with an evaporating tungsten wire and immediately decompose under the influence of high temperature. This prevents the vaporized metal from settling on the walls of the flask. The advantage of such lamps is an extended service life..

Device

There are several types of capsule halogen bulbs that differ in bulb size, shape, and the presence of special reflectors. They are united by the typical structure of the cap, the chemical composition of the gas mixture, the presence of a tungsten wire, which provides a glow. Halogen lamps for spotlights and industrial lights can differ in voltage: they work equally efficiently from 220, 380 V and miniature electricity sources 6-100 V. The brightness of the light is easily regulated by a switch with a rheostat.

Principle of operation

The main difference from traditional lamps is the constant halogen-tungsten thread self-healing process. When heated, the wire slowly evaporates, as in an incandescent bulb. The gas inside the flask reacts with metal atoms, capturing them and not allowing them to settle on the walls. The peculiarity of the obtained compounds is the impossibility of their existence at high temperatures, therefore, a decomposition reaction occurs, followed by the deposition of tungsten atoms back onto the thread. With a decrease in power by a rheostat, the temperature drops, and self-healing stops.

Life time

The glow temperature constantly maintains the incandescent filament due to the self-healing of tungsten by halogens in relative integrity. This increases the service life. The process is not ideal: the metal settles unevenly on the surface of the wire, thin sections gradually form. The average life of the device is 6000-7000 hours of continuous operation. Smooth inclusion through a rheostat increases it to 8000-12000 hours.

Advantages and disadvantages

Halogen lighting devices have a number of advantages and disadvantages arising from the features of the internal device, the principle of operation, and the possibility of operation. The pros include:

1. Long service life.
2. Stable operation, continuous light output.
3. Increased efficiency compared to standard incandescent bulbs.
4. Strength, resistance to mechanical damage.
5. Small size.
6. Reduced UV.

The disadvantages of this variety of lighting include:

1. Fire hazard due to heating of the flask to high temperatures. Before checking the halogen lamp with a tester, let it cool.
2. The gas mixture used in lamps is toxic to humans..
3. Unusual white color lighting.

Types of Halogen Home Lamps

The range of halogen lamps is very wide: from low-voltage lamps to large spotlights that can illuminate the stadium. Home light bulbs are available in three varieties:

1. With an external flask. Standard halogen lamps for a chandelier. External protection prevents fragmentation and gas spread after breaking.
2. With reflector. Designed to create a directional light source. Used in car headlights, flashlights.
3. Capsule. Miniature bulbs used in unprotected glass fixtures.

How to choose a halogen lamp

To buy halogen lamps for the home, decide what requirements they must meet. There are a number of criteria by which you can determine which model of a lighting fixture you need:

1. A kind of light bulb. Remember that linear halogen lighting fixtures are not suitable for the home. Other designs will be a good choice..
2. Voltage. Unlike traditional incandescent lamps, the models in question have a wider range of capacities. Determine what voltage will be in the network that supplies the lamp.
3. Flask material. Available are standard quartz models and made of tempered glass. The latter are better suited for living room lighting..

For the chandelier

Often you can find ceiling or wall lights, floor lamps, chandeliers equipped with halogen bulbs. The choice is justified: energy consumption is reduced, the level of illumination in the room increases. Learn how to buy a good lighting element for installation in a chandelier:

1. The size of the flask. Make sure that the bulb does not get stuck in the lampshade – they differ in size from standard.
2. Type of device. Choose varieties with an external bulb – they are ideal for household lighting.

For spotlights

The purpose of such special fixtures is to create a bright spot in a specific place. They are installed in several pieces at a short distance. Choose low-voltage halogen bulbs with reflectors: this variety forms a narrow beam of bright light. Choose the voltage and power, taking into account the number of installed devices.
