the device

The fluorescent lamp device has some design similarities with incandescent lamps and halogen products. It consists of a vial and sealed electrodes.

The flask is filled with inert gas and a small amount of mercury (up to 30 mg). The inner walls of the flask are covered with phosphor, which converts ultraviolet rays into light visible to humans. Electrodes are installed on both sides of the lamp (at the ends). The design of the electrode is the same as the tungsten filament to which the contacting legs are passed, which allows the electric current to pass through. The principle of operation is as follows – with the passage of electricity, the electrode heats up and creates ultraviolet radiation, which, passing through the walls of the lamp, is converted into a visible light stream.

Advantage

Technical characteristics of fluorescent lamps:

• Power range of products – from 15 to 80 W (for general purposes);
• Rated voltage – 220 and 127 V;
• Tungsten filament temperature – from 2700 to 6500 degrees (Kelvin);
• Light output – can reach a record 104 Lm / 1 W (average from 40 to 80 Lm / 1 W);
• Social size – 14 mm (customer E14) and 27 mm (standard E27);
• Vial diameter 12.16.26.38mm;
• Service life – from 10,000 to 40,000 hours;
• Efficiency exceeds 20%.

Species

We bring to your attention the main types of fluorescent lamps:

• line
• Contracting.

Linear fluorescent light sources are used to illuminate industrial and office buildings, as well as sports stadiums. Its advantage is high power and high light output. In addition, these products are able to save up to 30% of the electricity consumed, which is their main advantage.

Compact bulbs or in other words energy saving bulbs are used for general purposes. They have a specific design represented by a curved bulb. Products are used not only during the installation of lighting in the apartment, but also for decorative window decoration, as well as disinfection of hospital rooms. The main advantage is high light output and long service life.

Marking

Today there are many brands of fluorescent lamps, now we will consider each of them.

National

Local tags are represented by an alphanumeric abbreviation, which is decoded in the image.

The first letter “L” is lamp.

The second letter is the luminous flux characteristic (D – daylight, HB – cool white, TB – white, EB – natural white, B – white, UV – ultraviolet radiation, G – blue, C – blue, K – red, F – yellow, Z – green).

The third letter is the quality of color rendering (C – enhanced quality, CC – particularly high quality).

The fourth letter is a design feature (a – amalgam, b – fast start, k – loop, q – reflex, U-shaped).

The number after the letters is the power in watts.

We draw your attention to the fact that in the marking of fluorescent lamp abbreviations such as LHE and LE can be present, meaning natural light and cold natural light.

Overview of fluorescent lamp characteristics

Foreign marks are shown in this table:

As you can see, instead of alphanumeric encoding, a three-digit number is used, as well as an identification in the form of a simple signature in English (for example, the brilliant white brand means “cold light”).

Benefits

Energy-saving fluorescent lamps have a lot of advantages, therefore, in the global market of light sources they are in second place after the leading companies – LED products.

The main advantages are:

1. High energy saving indicators, in which they outperform incandescent lamps;
2. Good light quality and light output;
3. A variety of products for special and general purposes;
4. Long service life (an order of magnitude longer than halogen lamps).

cons

Among the disadvantages of fluorescent lamps are:

1. Increased cost of products;
2. Harmful effect on human well-being during prolonged use of artificial lighting. Moreover, these housekeepers are harmful to the eyes;
3. The service life is significantly reduced with frequent on/off light;
4. Failure with voltage drop (surge protection device must be additionally installed);
5. The light intensity cannot be adjusted with the dimmer.
6. It is forbidden to use it in dusty and damp rooms (for example, when installing electrical wiring in the bathroom);
7. Poor performance at low temperatures;
8. If the flask is broken, mercury can negatively affect the human body;
9. Requires specialized disposal, which may not be present in every city.

As you can see, these products have more disadvantages than advantages. However, with proper use, all the disadvantages “fly away instantly”, leaving only the main advantage – high energy-saving properties.

Application area

Today, the “housekeeper” is used wherever possible: for home lighting, for window decoration, street lighting. In addition, these light sources are widely used in the creation of televisions, such as the plasma screen belongs to the group of luminous sources.

The most suitable area for applying fluorescent lamps is the illumination of large areas: playgrounds, playgrounds and even the courtyard of a private house (as shown in the photo). This is due to the fact that these products have a high light output and at the same time will be turned on once a day.

So we found out the technical characteristics of fluorescent lamps, as well as the pros and cons of their use. We hope this information is useful and interesting for you!
