Lamp Types

1-Incandescent Lamps:

Glow filament lamps are based on the processes where the metal filament is heated up to high temperatures and then, as a result such heating, the filament wire emit radiation.

Incandescent lamps are manufactured in a broad scale in terms of size, quantity of light, and supply voltage. Supply voltage does not require any regulation procedure; they have low manufacture costs; and they can operate under both AC and DC current.


Due to their simple structure and easy operation characteristics, incandescent lamps were highly used in the lighting of houses and commercial structures. However, although they have high color efficiency, their light emittance efficiency is low. Within the scope of the studies carried out to efficiently use the energy, it is seen that the incandescent lamps gave way to the other lamp types. In some countries such as Brazil, Venezuela, Switzerland, Australia, USA, and Canada and in European Union countries, manufacture, importation and sale of incandescent lamps were prohibited due to their inefficiency.


2-Halogen Lamps:

Glow halogen lamp is a thermal light source formed with the change of the gas mixture (halogen addition) in the atmosphere of the glow lamp. Since the tungsten wire of the halogen molecules used in the atmosphere of such lamps are renewed, wire temperature may increase. As a result of this, both the light efficiency and the color temperature may slightly increase according to the glow lamp of the same power.


3-Fluorescent Lamps:

Invisible ultraviolet rays are begun to radiate as a result of heating and evaporation of mercury gas, which is available in fluorescent lamps through the filaments. These rays create bright light, which is seen by colliding with phosphor powder coated on the inner surface of the tube. These lamps can be found in different colors of light, power and type. Their yields are high and life is long. They need igniter ballast.


4-Compat Fluorescent Lamps:

These lamps are more compact derivatives of fluorescent lamps, which are manufactured. It is also known as “energy saving bulb”. Due to the size these lamps have, they can be used as highly-efficient solution for applications as equal of incandescent lamp. They need igniter ballast. Compact fluorescent (energy saving lamp) models having an igniter on itself as well as external mechanical and electronic ballast models of these lamps are commonly available


5- Metal Halide Lamps:

The large part of light is provided by high density discharge consisted of radiation of metal vapor and halogenure mixture. Their efficiency is very high. They need igniter ballast.


6-LED Lamps:

LED, which converts electrical energy into light, is a semiconductor circuit element. Obtaining the issues such as high light efficiency, low energy consumption, long life, better light directing level, low ultraviolet and infrared radiation, higher color rendering and different colors, successful results can be achieved with LED lighting devices.


In fact the feature, which makes LED sources totally unique, is the capability of producing color. LED sources, in addition to producing millions of colors, can provide a wide variety of color temperatures of white light.


LED sources, providing with the width of dim ability, also offer great advantages to the user providing with the width of dim ability. The fact that the LED light sources, which are basically electronic circuit elements, are used with electronic control systems brings quite different results.
