Lamps exist in different types and models that can be divided based on different factors. One of the important factors in the classification of types of lamps is their manufacturing technology.

1- Incandescent lamp

Incandescent bulbs are the normal and traditional lamps that use tungsten filament in their structure. When the current of electricity passes through this thread, it causes it to glow and the so-called light bulb turns on. The tungsten filament in the bulb of incandescent lamps is surrounded by vacuum or nitrogen gas. Incandescent lamps are available in different sizes and shapes, and one of them can be chosen according to the need and application. Incandescent lamps work in such a way that the passing of a sudden current causes the tungsten filament to heat up and burn. These lamps have an average lifespan of between 700 and 1000 hours, and one of their disadvantages is high energy loss.

2- Fluorescent lamp

Fluorescent lamps, better known as moonlight lamps, have a more complex structure than incandescent lamps. In these lamps, there is a fluorescent tube in the distance between the cathodes. The inside of this tube is filled with mercury and some other gases, the passage of electricity through them causes the production of light and radiation. The phosphor coating on the outside converts radiant energy into visible light. Compared to incandescent lamps, fluorescent lamps require less energy to produce light and therefore are more durable. Considering that these lamps are filled with mercury, it is difficult to dispose of them after the lamp burns out, and safety tips must be observed in this regard. Fluorescent has a longer lifespan than filament and consumes less electricity.

3- Compact fluorescent lamp or CFL

CFL (Compact Fluorescent Lamps) are an alternative to incandescent lamps in buildings and homes. CFL lamps have the same performance and structure as conventional fluorescent lamps, except that they can produce the same amount of light with less energy consumption. The structure of these lamps consists of several tube rings filled with mercury, which is very similar to the bulb of incandescent lamps. These types of lamps have a longer lifespan compared to incandescent lamps and can work up to 10,000 hours. Also, these lamps have lower energy consumption and higher brightness than incandescent lamps.

4- Halogen lamp

Halogen lamps can be considered an improved version of incandescent lamps. The difference between these types of lamps and incandescent lamps is that the tungsten filament inside the lamp is covered with a transparent coating and they are also smaller than incandescent lamps. The reason for naming these types of lamps is due to the use of small amounts of halogen along with an inert gas. The inert gas used in these lamps can increase the brightness and lifespan of the lamp and increase its efficiency and brightness significantly. Today's halogens in the market are called with this name only because of the similarity with previous halogens in terms of structure, otherwise SMD and COB technology are used in their production.

5- LED lamp

LED lamps are lamps that are designed and produced with new technology with high efficiency. In an LED lamp, light is emitted by the passage of electrons in a semiconductor. These types of lamps do not have tungsten filaments and have more power and a much longer lifespan. One of the features of these lamps is the ability to create a different color spectrum without using color filters. Compared to incandescent lamps, these lamps have the ability to produce more light. The energy consumption of LED lamps is lower and they are more efficient than CFL lamps.LED bulbs are unrivaled in terms of lifespan and can last up to 100,000 hours. Specific light range, high safety and reasonable price are other features of LED lamps that have led to their high popularity. These lamps, which have the ability to convert 90% of electrical energy into light, are divided into different types. To learn more about this product, you can read the article "What is an LED lamp?" read the Among the most important types of LED lamps, we can mention SMD lamps and COB lamps.

Types of LED lamps

SMD lamp: The term SMD stands for Surface Mount Diode and each unit or chip consists of 3 LEDs with red, green and blue light colors. This new technology brings high efficiency and longevity to the LED lamp. SMD lamps are very efficient, have a variety of colors, high resolution, very small volume, more viewing angle, and significantly save energy consumption.COB lamp: the latest technology in the production of LED lamps, which are considered a long step forward to use more energy. These lamps are equipped with a powerful chip that, unlike SMD lamps, has only one power input pin. The amount of high lumen production for low energy consumption makes these lamps to be used in smartphone screens. These lamps are small sources of light production with a long lifespan, which have earned the title of controllable sun.
