Overview of the characteristics of halogen lamps

The halogen lamp unit has much in common with an incandescent lamp, which is installed in almost every apartment building. This bulb consists of a bulb, tungsten filament, electrodes and a group of contacts, as shown in the picture.

Product design

The main structural difference between halogens and incandescent lamps is as follows:

inside the bulb there are pairs of bromine and iodine, instead of an inert gas( or vacuum);
the material for manufacturing the flask is quartz.

These two differences significantly extend the number of working hours of the product, as well as its efficiency( we'll talk about this a little later).

Characteristic

Main technical characteristics of halogen lamps:

power range ranges from 1W to 20 kW;
rated voltage can be 6 /12/24/110/ 240 V( depending on the application conditions);
heating temperature of tungsten filament is about 3000 degrees;

light output - from 15 to 22 lm / 1 W;
the size of the socle is 17 mm( E17, "minion") and 27 mm( E27 standard);
, the service life is from 2000-4000 hours during normal operation( with a smooth start-up, the mark can reach a record 12,000 hours).

Species

To date, there are 4 main types of halogen lamps:

Linear
With external bulb
With reflector
Capsule

Let us briefly examine each of the types of products, plus the pros and cons of each option.

Linear halogen lamps were made in the last century( in the 60's).They have a special design - oblong cylindrical shape with two plinths. The power can reach 20 kW, so they are used both in everyday life and industrial use( searchlight).The advantage of these light bulbs is their high strength properties and brightness. The drawback is increased power consumption.

Linear

Halogen bulb with a double bulb( external) is practically the same as the classical version, but if you look closely, another small bulb can be seen inside the glass shell, as shown in the photo. An external bulb is used to protect halogens from human contact and mechanical damage. To date, there is a wide range of lamps with an external bulb: matte, milky shade, decorative form, etc. The size of the socle can be standard( E27) and reduced( E14).

Bulb with outer bulb

To make the light flux directed, the bulb is covered with an aluminum or infrared reflector. As a result, lighting becomes the most effective, becauseall light is directed to the necessary area of the room. Most often, these versions are used for the installation of concealed ceiling lighting( spotlights),

There are many types of halogen lamps with a reflector: with a protective glass, without it, etc. The cap type is represented by a two-pin contact group of various sizes( the distance between the contacts can be from 3 to 10 mm).

With reflector

Capsule models have miniature dimensions and relatively low light output. Most often capsular halogen lamps are used exclusively for decorative purposes, for example, for lighting furniture.

Capsule

As in the previous version, the plinth can have several sizes: from 3 to 9 mm between the contacts.

Marking

The marking of halogen lamps for CIS countries is as follows:

the first letter is a material for making a flask( "K" means quartz);
the second letter is the name of the gas in the flask( if "G" is halogen, if "I" is iodine);
the third letter - features of a design( "M" - small-sized);
the first group of digits is the operating voltage in Volts and the nominal power in Watts through a hyphen;
the last digit is the revision number of the product( unlike the base model).

Decoding of

marking Advantage of

The advantage of halogen lamps is as follows:

small dimensions;
relatively long life( 2 times more than incandescent lamps);
moderate power consumption;
have increased mechanical strength and heat resistance due to quartz shell design;
increased light output;
the luminous flux can be adjusted;
low cost;
wide range of products for various applications.

Disadvantages of

There are several disadvantages of halogen incandescent lamps:

is categorically forbidden to touch the light bulb with your hands.this can significantly shorten the service life;
products fail when voltage drops, so for their work it is necessary to invest in the purchase of an overvoltage protection device;
halogen bulb heats up to high temperatures, so you need to take care of the fire safety in the installation work in advance.

Scope of Application

The field of application of halogens is very diverse. Products are widely used in automotive lighting, decorative lighting, street lighting, as well as in photo and video. Very often they are used during the installation of lighting in an apartment and a house. Also, the bulbs can be used as a heating element for a microwave oven and an electric stove.

Here we have considered the main advantages, disadvantages and technical characteristics of halogen lamps. We hope that in the article you found all the answers to the questions that have arisen. If this is not the case, please contact our specialists in the category "Q & A"!
