How do you see fluorescent lights and how do they differ from linear ones?
Fluorescent fluorescent lamps can come in a variety of shapes. And don't try it hard from vsichki. Deserving and all whitening, che samata krushka, phosphorus is applied to the top, serving as a source of light. The result is a solid cylindrical luminous surface. No one else is the source for Svetlina yama tazi function. Tezi lampi are made of original dori without a canopy and lampshades. We’ll talk for a while for a circle of fluorescent lamps for a general crawl.

Device and principle for action
A wall-shaped fluorescent lamp, like any fluorescent lamp, and 2 electrodes, grading in opposite edges on the crucible, directing it under the format onto the spiral from the pressed button. The glassy shell is covered with a phosphor, which transforms the ultraviolet radiation into a spectrum from light, we see for the chorat. For a starter on a lamp, all equipment for control on a starter is from electromagnetic (PRA) or electronic (ECG) type.
When directed to the flask from it, the air is evacuated, a trace of some flask is filled with an inert gas argon or a mixture with an additive for neon or krypton. Zhivakt se vvezhda kato active substance, some giving ultraviolet radiation in time to ionization. Kogato lampata se sunk, zhivakt preminava in a state of steam.
For curing on kolbat, they use halophosphate phosphorus on basate on calcium or other alkaline earth metals, most often technite silicate compounds. A different combination of inert gas and phosphorus components allows you to get a different spectrum from daylight and color reproduction.
Base the elements on the ballast and throttle and starter. Droselt osiguryava electromagnetic impulse for electrical discharge between two electrodes and limiting the working current. The starter is a compact gas discharge lamp with bimetal contact. The task of shutting the wire between two cathodes in a short time is not a good one, so that the current starts and premine the coil, the gas heater and the livestock. For yes, they named the reactive component, which they gave an inductor, adding a capacitor to the compensator.
A simple classic circuit connected to a fluorescent lamp
Once upon a time, this was the case when the throttle was applied to the electrode on the lamp and the starter, in the latter, forming a luminous discharge, which polluted the bimetal contact. When heated, the contacts of all of the fire and the closure of the electric chain. Wind up the dirt current on the cathode, which from your own country pollutes the inert gas and currents of livestock, turning it into livestock bets.
Once contacted on the starter sa closure, the discharge of the spiral is illuminated and contact is made to cool down. At the moment on the boil, the contact is sharply painted on the starting current and the inductor generates an electromagnetic pulse up to 1 kilovolt. The goods are sufficient for the formation of a discharge between the cathode in the betting gum. Appearing this is a constant electric arc. The voltage between the cathode is significantly lowered, so that the starter does not repeat the light discharge.Ako the discharge between the cathode didn’t appear or the electric dag e beat the pressure, then the voltage from 220V reappeared again at the top of the cathode and contact the starter and process on the starter of the repeater. Under normal conditions, the lamp is put into operation for no more than 1 second.
An electric arc is obtained, which is the connection between the phase and zero conductor. Throttle is an inductive resistance that somehow limits the flow of current. A capacitor is required between the phase and zero conductor (C1 on the diagram), in order to compensate for the reactive current, and therefore the damage to the reactive electricity in the circuit. The capacitor between contacts on the starter (C2) serves as a protection on the contact. When boiling, preventing the formation of a sparking arc, which may damage the contact. Capacitors do not affect the top of the starter and work on the lamp and may not be present in the voltage.
Under the influence of an electrical discharge in a flask with an inert gas and a sour beer, forming an ultraviolet radiance. In golyamata, radiation from the Tazi is often invisible beyond the human eye. But phosphorus, curving the bulb, under the influence of UV radiation, let's see the spectrum for radiation. Therefore, a person sees a shining crush and a bright one, isolated from her.

Scheme on a fluorescent lamp with a wall
How is it necessary to use a wall-shaped fluorescent lamp? Get it right, PRA. The ballast of the sensor is also a ballast, which is one of the functions on the ballast and limits the operating current. In the electrical equipment of the device, for the limited current, ballasts are called.The role of this one is from the throttles or the resistor in the chains without the throttles. In an electronic ballast, a choke with a lower power, a resistor and electronic elements: transistors, other semiconductors can be used to control current.
Electronic ballasts allow you to work with fluorescent lamps from a source for direct current.
What kind of ballast is needed for a wall lamp? Nyama is a separate circuit for connecting to a lamp with a prusten. Any circuit for a linear, U-shaped, spiral or other type of fluorescent lamp is more work for a circle.
And so, why is it sensible to have a lot of different schemes for using fluorescent lamps? Many types of schemes are explained with a desire for a developer and an amateur, but they will comprehend, start it on a lamp, and other goals:
- paint on disperse for the elements on the manager, it was achingly prickly;
- a starter without using the throttle valve and (or) a starter kato nay - skip the elements on the control mechanisms;
- start-up and operation from a source to direct current;
- starter with burnt out niches on the cathodic coil;
- connected and startered by two lamps at the same time;
- gentle start mode with limited start current;
- soils at low temperatures and negative temperatures (zhivakt preminava in a gaseous state at +30 - +40 0С);
- start-up and support for work at low voltage in the mrezhat.
Different schemes for control mechanisms behind a starter on a lamp without throttles, starter, with electronic ballast, with burnt out coils, from battery + 12V
Whenever you choose a scheme for hooking up to a wall lamp, shaking it up and picking up the foresight of the conditions for work. All of you from tyah ima, your predominance and shortcomings. Install the lamps and use them mainly in room fuels under standard conditions.Consequently, other factors may be important in the selection for ballast.
How shall we choose the mechanism for control? If a standard ballast is chosen, it is available in a commercial area, the power of a wall-shaped fluorescent lamp is more decisive. For yes, increase the power, shake and increase the distance between the electrodes. But there is a sharply clear distance, a sensible high-pitched trembling and a pulsed voltage - for a hopeful electrical discharge on an inert gas between the electrodes. In the case of a silat at the beginning and work, the current is increased by a lot. Therefore, there are other parameters that correspond to the power of the lamp. This is why it is important, yes, you know, there is a strong lamp on the lamp, when you choose the controlling pressure. And on the very mechanism for controlling the manufacturer, try and set the range to the power on the lamp, which can and can connect to it. Do not tryabva and all use ballasts and electronic ballasts with lamps with unsuitable power.

Distinguish between round and linear form
Lineate fluorescent lamp ima right krushka. The current discharge between the electrodes is right. In a presten lamp, a krushkata ima format on a torus. Discharge on the current of repeating the format on the crank. The format on the lampata does not affect the top of the principle on the effect on the lampata. But still there are structural differences.
The pre-walled lamp and the katodi are close to one another and there is no need for a durpate and a crite conductor of the opposite winding.
Applications and features
Svetlinite on the wall gives a lot of mek, the syanka is smeared.Izpolvayki nekolko from tezi iztochnitsa, you can and comprehend the effect without syanka. Tozi has a specific effect and is very useful when working with nature in a flock for photography, video filmed, and somehow when working on grimiori and grimiori. Nay-kindly illuminated on the object's volume and allow you to correctly determine the tonality on the nuance and color rendering on the object from different countries.
For yes, you will achieve these goals, you can crawl other sources to light, put them around the perimeter on flocks. But the lampata on the presten ima is one main predominance. Svetlinniyat flow all the way from the surface to the krushkat. On the other hand, if we take different types of lamps with a single stream of light, then a person can look at a luminescent pot relatively calmly, without closing the eyes or grafting on the eyes. It is still impossible to see directly here a lamp with a lit lamp or LED, as they are before the person and shine in the face.
Light with a pinch of honor for this designer decoration on the flocks, presentation of the subject and purpose of the presentation. They brightly illuminate the object, do not hurt the eyes and do not stop looking at the objects on the edge. Ima lampi, work for technical premises, garage, maze. Ima dori prustenovidni squares, crawling for illumination on a golyama magnifying glass. There are a lot of situations, when a compact wall-shaped lamp is much better than a linear lamp.

Color rendering and color temperature
Characterize the medium for every cup, which reveals a color rendering and a color temperature. There are similar characteristics for a light source, but they are measured by different methods and have different units.
The color is given depending on the width of the spectrum on the visible light, which is the source of the radiation. But in the spectrum of the source of Lipsva, they bloom somehow, but it is still impossible to see them bloom. This is very important for protection from the source and giving light to the spectrum, much close to the sun. Vidimiyat naturally slanchev specter of reception of katonosti from 100 RA. For fluorescent lamps and tasi, the cost can be from 60 to 95 RA.
Index on color rendering for different light sources
The color temperature on the lamp is shown to some extent from the spectrum of vision, it is close to very strongly radiant. It is measured in Kelvin (K) from 1000 to 10000. The temperature of the light is at 2700 to 3500K, it was natural - 3500-4000K, it was cold - 4000-5000K, it was daylight - 5000-6000K, it was cold daylight. hva over 6500K.
Color map for temperature in Kelvin for light source
Some markings of fluorescent lamps, color rendering and color temperature are indicated by the manufacturer's digital code. Each brand has its own brand. But everything is better because of the tridigital OSRAM code, it is indexed for the color rendering of the cryptiran into a private figure, sometimes you can multiply it by 10 and so and so get the value by RA. The following two numbers indicate the color temperature, and then multiply by 100 to get the value in Kelvin. For example, the code 830 means that the lamp is CRI 80 and the color temperature is 3000K.
Coding on the index on the color rendering and color temperature in the marking on the lamp
Lampite, produce in Russia, maybe imate bitovi markings. The pure letter L is luminescent. Osventova bloomed soochen: TB - heat was hot, B - hot, D - daytime, HB - it was cold. Lampite with color matched scho imate letter C.For example LDC - 40, fluorescent, daylight, color adjusted, 40 W.
For the sake of specifics on the application, it is on round fluorescent lamps, they will produce in an honorable way with a well-matched color rendering. For yes, I have comprehended the effect in the color rendering and the proximity to the quality, to the lightness to a dimly bright light, it is used on slightly lamps with different colors and temperatures.
Nay-good-bye, please, lamps
When choosing to find a lamp, I will take the foreseeing of RA and the markat to the manufacturer. Lightning flow of treabva and compliance as much as possible with the spectrum and lampata treabva and work correctly for the purpose of si exploitation belly. They produce fluorescent light sources with color definition and characteristics with different powers.
