Features LL connection to the network
Fluorescent lamp - a practical and cost-effective module for the organization of lighting systems in domestic, industrial and technical areas.
The only difficulty lies in the fact that directly connect the device to the centralized elektropodayuschim communication is not possible.
Electromagnetic ballast consumes about 25% of the capacity of the lighting device, thereby reducing to a quarter of its effectiveness and efficiency level
This is due to the fact that the creation of a stable discharge in activating Fluorescent lamp type and the subsequent restriction of the growing power demand of organization of some specific physical conditions. It is these problems are solved by the installation of the ballast unit.
What is the ballast
Ballast is a device regulating actuating function and connected to the electrical communications fluorescent lighting.
It is used to maintain the correct mode operation and effective control of the operating current.
Acquires increased relevance when there is insufficient network electrical load and there is no necessary limitation in current consumption.
The general principle of operation of the element
Inside fluorescent lamps is electrically conducting gas environment having a negative resistance. This is manifested in the fact that with increasing current greatly decreases the voltage between the electrodes.
It compensates for this time and ensures correct operation of the lighting device that connects to ballastnik control system.
When a large amount of current for the power supplied to any luminescent device, it may be damaged. To avoid this, in the design of the lamp is turned on ballast, inverter performing functions
He's on a short period increases the overall tension and helping Fluorescent light up when the central network for this resource is not enough. Additional features of the module vary depending on their design features and performance type.
Types and characteristics of ballasts
Today, the most widely distributed electromagnetic and electronic ballasts. They operate reliably and ensure the proper functioning of a long and comfortable operation of fluorescent lamps of all types. They have the same general principle of operation, but differ slightly on certain opportunities.
Features of electromagnetic products
electromagnetic type ballasts are used for lamps, connecting to the central mains using starter.
Supply voltage in this embodiment is accompanied by discharge, followed by intense heating of the electrode and the closure of bimetallic elements.
Electromagnetic ballast from the electronic different even in appearance. The first has a massive, high structure, and the second is an elongated thin board on which all operating elements are arranged
At the time when the starter circuit electrodes occurs, the operating current increases sharply. This is due to limitation of maximum resistance choke.
After complete cooling of the starter the bimetallic electrodes disconnection occurs.
If electromagnetic ballast design fails starter, Fluorescent work appears a false start. In this case, at the time of switching on and immediately before full ignition lamp blinks 3-4 times and then begins to burn. This leads to unnecessary energy consumption and significantly reduces the overall service life of the light source
When Fluorescent starter circuit is opened in the induction coil is formed immediately active high voltage ignition pulse occurs and the lighting unit.
The advantages of the device include:
- high reliability, proven time;
- operational comfort of the electromagnetic unit;
- ease of assembly;
- reasonable price, which makes the product attractive to manufacturers of light sources and consumers.
In addition to positive moments, users will notice a long list of disadvantages that spoil the overall impression of the device.
Among them are noted items such as:
- presence gating effect in which the lamp flickers at a frequency of 50 Hz and causes an increase in fatigue levels in humans - it significantly reduces performance, especially when the luminaire is in work or school premises;
- a longer time is required to run the fixture - 2-3 seconds at the beginning and up to 5-8 by the middle-end of the service life;
- specific audible hum throttling device;
- high power consumption, which entails an inevitable increase in bills for utilities;
- low reliability starter element;
- cumbersome design and its substantial weight.
When you purchase all of these conditions must be considered in order to understand what it would cost operation of home lighting system, equipped with luminescent in the future.
Electronic ballast units
type electronic ballast used for the same purposes as the solenoid module. However, by design and by the principle of their duties, these devices are quite different from each other.
Cheap electronic ballast has a simple Autogenerating circuit with a transformer output stage and the base functioning bipolar transistors. Big disadvantage of these devices - the lack of protection against abnormal operating conditions
The wide popularity to the articles came in the early '90s. At this time they began to use in conjunction with a variety of light sources.
Initially high as compared with electromagnetic value products manufacturers compensated good efficiency devices and other useful characteristics, properties.
The use of electronic ballasts can reduce the total electricity consumption by 20-30%, while maintaining the full richness, power and strength of light stream.
This effect was achieved by increasing the light output of the lamp base at a higher frequency and a significantly higher efficiency compared to electronic modules with electromagnetic.
The most vulnerable electronic ballastnika this fuse elements (1), a condenser (2) and transistor (3). They usually fail for various objective reasons and lead bulb inoperable
Soft start and gentle operating mode enabled by almost half lyuministsentam prolong life, lowering in this way the overall operating costs for the lighting system. Lamps required to change much less frequently, and the need for starters gone at all.
In addition, using electronic ballasts managed to get rid of the background noise and the workers expressed annoying flicker, parallel to achieving a stable and uniform illumination of the premises even when the voltage fluctuations in the network within 200-250 AT.
To fluorescent lamp is not humming and flickering, you need to feed it only with high frequency current of 20 kHz or more. To achieve this task in turn should comprise a rectifier circuit, HF high voltage generator and the ballast, which plays the role SMPS
In addition, the opportunity to control the lamp brightness, adjusting light stream to the individual wishes and needs of the user.
Among the major product advantages distinguish the following criteria:
- low weight and compact design;
- almost instantaneously, a very soft start, do not have too much load on the fluorescent lamp;
- complete absence of visible eye blinking and distinguish sound effect;
- High operating power factor of 0.95;
- direct saving of electric current of 22% - the electronic module is practically not heated as compared with the electromagnetic and consumes unnecessary resource;
- additional protection is mounted in the unit, to ensure a high level of fire safety, and reducing the potential risks arising in the course of operation;
- Fluorescent significantly extend the service;
- light stream with good color density, without fluctuations even with prolonged burning does not cause eye fatigue people in the room;
- High efficiency of the lighting device at low temperature indicators;
- Ballast ability to automatically adjust the parameters of the lamp, thus creating optimum performance for themselves and the fixture.
Some manufacturers equip their electronic ballasts special fuse. It protects the device from electrical surges, fluctuations in the core network and an erroneous activation of the lamp without a lamp.
Today bodies dealing with occupational safety and health, it is recommended in order to improve working conditions and productivity, equipped with fluorescent lamps installed in the office premises, it is electronic, rather than electromagnetic launchers devices
Of the minuses of electronic products usually mention only the cost is significantly higher compared with electromagnetic modules. However, this can be important only at the moment of purchase.
In the future, in the course of intensive use, the electronic ballast is completely fulfills its price and even begin to generate profits, saving electrical life seriously and taking some of the load from the source Sveta.
Ballasts for compact fluorescent lamps
fluorescent Lamp Compact Type are devices similar to a conventional incandescent lamp screw base E14 and E27.
They can be placed in the modern and vintage chandeliers, sconces, floor lamps and other lighting fixtures.
Due to the structural features of compact Fluorescent to electronic "stuffing" of increased requirements. Brands always consider them in the production and unknown manufacturers to reduce the cost, change many elements into simpler. This significantly reduces the effectiveness and module life
Equipped with devices of this class, as a rule, progressive electronic ballast, which is integrated directly into the internal structure and is usually located on the motherboard of the lamp product.
What to look for when choosing a
Choosing a ballast for a fluorescent lamp, the paramount need to pay attention to such parameter as the power module.
It must exactly match the power of the luminaire, or the lamp will be unable to function fully and to give light stream in the desired mode.
Include ballast in the no-load network is strictly prohibited. The device can immediately burn out and have it repaired or buy a new
Next you need to determine what kind of ballast is required to purchase. For the price more favorable electromagnetic elements. Their cost is low and installation is usually no complications.
However, such devices are considered obsolete, are bulky size and consume additional energy resources. It significantly reduces their appeal, even though the original price available.
To check the serviceability of the electronic ballast, useful special measuring device - Pocket Oscilloscope
Electronic devices are much more expensive. Especially this point concerns products produced steep branded manufacturers. But their price is compensated by the energy-efficient, practical, flawless assembly and high overall quality of the devices.
