Overview of the characteristics of fluorescent lamps

device

device fluorescentlamp has some similarities with the design of incandescent and halogen products.It consists of a sealed flask and electrodes.

flask filled with an inert gas and a small quantity of mercury (30 mg).The inner walls of the bulb are coated with phosphor that converts ultraviolet light into light visible to humans.The electrodes are mounted on both sides of the bulb (at the ends).electrode design is all the same tungsten filament, which are soldered to the contact legs, an electric current.The operating principle of the following - by passing electricity electrode is heated and there is ultraviolet radiation, which passes through the walls of the bulb is converted into visible light output.

Feature

Specifications fluorescent light bulbs:

• product range of capacities - from 15 to 80 W (general purpose)
• Voltage Rating - 220 and 127 V.
• incandescent tungsten filament temperature - from 2700 to6500 degrees (Kelvin)
• Luminous efficacy - may reach a record 104 lm / 1 W (average of 40 to 80 lumens / 1 watt)
• cap size - 14 mm (EP E14) and 27 mm (standard E27).
• bulb diameter - 12,16,26,38 mm.
• lifetime - from 10,000 to 40,000 hours.
• Efficiency exceeds 20%

types

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

• Linear
• Compact

linear fluorescent light sources are usedfor light industrial and office buildings and sports fields.Their peculiarity and improved high power light output.In addition, these products are able to save up to 30% of electricity consumption, which is their biggest advantage.

Compact or in other words, energy-saving lamps (CFLs) are used for general purpose.They have a specific structure represented by the flask curved.Products are used not only during the installation of lighting in the apartment, but also for decorative lighting displays, as well as disinfection of hospital rooms.The main advantage is the high light output and long service life.

Marking

To date, there are several fluorescent labels now look at each of them.

Patriotic Patriotic

marking provided alphanumeric abbreviation that decoded the image.

first letter "L" - Light.

second letter - feature luminous flux (D - day, HB - cool white, TB - White, EB - naturally white, B - white, UV - ultraviolet, D - Blue, S - blue, K - red, M- yellow, G - green).

third letter - quality color (C - improved quality, CC - very high quality).

fourth letter - a design feature (-amalgamnaya A, B - quick start, K ​​- ring, P - reflex, have - have shaped).

numbers after the letters - the power in watts.

draw your attention to the fact that the labeling fluorescent lamp may be present such abbreviations as LHE and LE, which means that natural light and cool natural light.

International

International marking is presented in the following table:

As you can see, instead of alphanumeric cipher using three-digit number, as well as the definition of a simple signature in English (toexample, mark cool white or translated "cold light").

Benefits

Energy saving fluorescent light bulbs have many advantages, so second place behind leaders take on the world market of light sources - LED products.

1. high energy-saving performance, and what they are superior to incandescent bulbs;
2. Good light quality and light output;
3. wide variety of products for special and general purpose;
4. Long life (an order of magnitude longer than a halogen lamp).

Disadvantages

Among the disadvantages of fluorescent lamps emit:

1. increased cost of products;
2. harmful effects on human health with prolonged use of artificial lighting.In addition, such a housekeeper harmful to the eyes;
3. service life considerably shortened by frequent on / off light;
4. of failure when the voltage drops (you need to install an additional surge arrester);
5. Light intensity can not be adjusted using a dimmer;
6. Do not use in dusty and wet areas (for example, when installing wiring in the bath);
7. Poor working at low temperatures;
8. If flask broken, mercury can adversely affect the human body;
9. require specialized disposal that may be present is not in every city.

As you can see, the shortcomings in these products more than the benefits.Still, when used properly, all the flaws immediately "fly away", leaving only the main advantage - high energy-saving properties.

Scope

Today "housekeeper" are used wherever possible: for home, for the illumination of shop windows, street lighting.In addition, these light sources are widely used in building televisions becauseplasma screen refers to a group of fluorescent light sources.

most appropriate area of ​​application of fluorescent lamps is to illuminate large areas: stadiums, playgrounds and even a court in a private home (as shown in photo).This is due to the fact that such products have a high luminous efficiency, and thus would be included once a day.

So we dealt with the technical specifications of the ins and outs of fluorescent lamps.We hope that this information was useful and interesting for you!
