How are miniature devices

Energy-saving bulbs are much smaller than the standard, able to create thanks to cardinal processing design. Very luminous tube learned to curl spiral, bend a few additions like an accordion, performed in the classical round or pear-shaped.

Features of the structure of the bulb

It is an opportunity to give the desired shape has become a major achievement towards the development of compact fluorescent lamps (CFLs). All other minor obstacles to overcome with the help of electronics.

Apparatus similar equipment includes three major components: a glass flask ballast and socket.

Kolb products on the inside is coated with phosphor. It converts ultraviolet rays generated by the device in the luminous flux, which will be visible to the human eye.

Performance, light color and other parameters of the lighting of the lamp depends on the quality of the composition of the substance.

The device is compact fluorescent lamps

The flask bulb electrodes are mounted tungsten, which is applied to the surface of the active complex mixture of chemicals - calcium, barium and strontium. The space is filled with an inert gas added with about 3-8 mg of mercury

Phosphors used in the manufacture of CFLs are based on rare earth elements. They are different from those used in the manufacture of linear fluorescent devices.

Their cost is several tens of times higher, but is completely justified by the fact that this group of substances capable of functioning in conditions of high density of surface irradiation.

This feature will significantly reduce the discharge tube diameter.

Variations as compact light bulbs

The range of compact fluorescent lamps meet various forms: U-shaped with a certain number of tubes, the F-type, spiral, circular, candles

Types of electronic control mechanisms

Since fluorescent lights can not work from a network directly in their designs provided an accessory for connection - internal or external Ballasts.

Ballast in the lamp

Electronic ballasts are powered by high voltage, which increases the luminous flux and efficiency and reduces the lamp to flicker. The better and more reliable mechanism, the longer is the light

During startup electronic component heats up the electrodes, and then maintains normal current output parameters regardless of voltage surges.

Lamps with external electromagnetic equipment called not integrated. They are equipped with unusual cap, series connected choke and starter.

Variety of plinths CFL

Mini representatives fluorescent lamps equipped with one of the two types of caps: Pin or screw.

screw caps «E» indicate the mark. It is the most common type of connection that is identical to a simple incandescent bulb.

Types of caps compact fluorescent lamps

For small lamps provided minions E14. Into a standard household socket fit chucks E27, more powerful and dimensional - E40. Thread diameter in millimeters of products determined by the digit surrounding the labeling

plinths G connects the bulb with a cartridge according to a special pattern of pins through the system - they are usually two or four. The most popular among them are G23 and G27. Basically, they screwed into table lamps.

In industrial premises and outlets common lamp socket G24. For installation in drywall and stretch ceiling system is ideal basement G53.

What are the principles functioning equipment

CFLs work by analogy with linear fluorescent lamps, but on a smaller area. Luminous tube-bulb filled with an inert gas and mercury vapor. On both sides there are arranged filament.

Running lamp comes with an electronic control gear enclosed in a plastic case.

At the time of inclusion in the interior of the flask is carried out electric discharge. Thereafter, ultraviolet light is emitted. Phosphor present on the tube walls, transforming it into visible rays.

Strengths and weaknesses of the product

Like any other light source, fluorescent bulbs with a number of small dimensions peculiar advantages and disadvantages.

The color temperature of light bulbs

Small luminescent devices emit light in a variety of color spectrum. Their scope is very wide: from offices and residential buildings to industrial and commercial buildings

Numerous feedback from users of such light equipment given many positive nuances:

  1. High performance. For equal values ​​of wattage CFL light stream more than incandescent bulbs parameters 5-6 times.
  2. Sensible energy saving. According to the average estimate, the luminescent light source gives up to 80% of the resources for lighting, and up to 20% - in the heat. In this regard, the light output device 20 W 100 W would be similar conventional bulbs.
  3. Durability. Duration stable operation CFL - 6-12 thousand hours. More specific figures are dependent on the manufacturer, compliance with operating standards, frequency on / off the device.
  4. The low temperature of the flask. Bulbs emit a minimum amount of heat, and therefore they can be safely screwed in devices in which the temperature limitation provided instructions.

Compact fluorescent lamps provide the correct and powerful light emission. Light rays are reflected in the total area of ​​the flask surface, illuminating the room brightly and evenly.

Intervals between cycles on / off

Devices can not withstand a short on-off cycles. According to the established standards producers, a break between them should be not less than 2-3 minutes

Deficiencies in equipment also missing.

The negative points should include:

  1. Quite a long start-up. Lamp ignited after 0.5-1 second after switching on. Some models require installation time of full light output in the range of 10-15 minutes.
  2. High ripple, noise, flicker in products equipped with an external gear. This causes rapid fatigue, bad for the overall health of people in the room.
  3. Flash off. This phenomenon occurs due to sudden discharge of the capacitor and can reduce service life.
  4. Sensitivity to moisture and low temperatures. CFLs do not work after temperature readings fall below zero.

It should also be noted that the lamps are not compatible with standard light control dimmers. In the market, there are separate versions with dimming function values, dimmers, connecting by the special scheme.

When the random destruction of light sources there is a high probability of chemical contamination. Strong poisoning can cause mercury vapor contained in the flask.

Disposal of Fluorescent Lamps

Burned lamp shall not be treated independently and disposed of in general waste bins. To this end, better to turn to specialized reception centers mercury-containing waste

To avoid unpleasant symptoms, you need to quickly collect smashed the flask into a container filled with water, and then thoroughly rinse the floor with potassium permanganate and ventilate the room.

Detailed information about the recycling of fluorescent lamps is presented in this article.
