Types of DNaT lamps and their technical characteristics
Title: Specialization 
Before the decade of the year, sodium lamps were crawling for lighting on birds and streets almost everywhere. From the appearance on the LED source to the light, those backs and all are used a little in order, but in spite of the HPS, the lamp does not barzat and all will refuse to position the si. How are the lights and how to protect the current position of the environment street lighting from the decade? Let's take a closer look at this experience.

How do you see the HPS and lamps
HPS lamps are single from a variety of sodium and high-pressure lamps - NLVD (English HPS Lamp - High-Pressure Sodium Lamp). DNaT is an abbreviation, decoded to mean "Arc Sodium Tubular". Name a few different device types from tosi type: DNaMT, DNZ and DNaS. We see some how they work and how they differ from each other.
Sodium lamp design
Structurally, the device is a flask, made from a special aluminum oxide Al2O3 glass bowl. According to the time for the work of the kolbat, it is dirty up to 1200 degrees Celsius. Such a glass is not in itself the cost of high temperatures, but it is the same in the state and the cost of the destructive effect on the sodium bet.
Two electrodes are drunk in the flask, the burner is named.Samiyat toy e pjlen sjs mixture of buffer (inert) gas with additive for sodium amalgam: alloy for sodium with zhivak. Dolnitelno kjm buffer gas se adding xenon, koito osiguryava in-forest start on krushkat. A burner from its own country, having put a foreign flask in a friend, is made from ordinary heat-resistant glass. Commonly used refractory borosilicate glass. In the kolbat, there is a long vacuum, and the samata is also equipped with a base from one or another type for connecting to the electrical network.
Thanksgiving on the vacuum of the vnshnata flask acting like a thermos, some osiguryava normally starter and work on a sodium burner at a low temperature for a round environment. In the meantime, paint on toplinnite ruin, increase efficiency and resource per device.
HPS lamp unit
Nai is a crossed base, installed on HPS mugs, not based on Edison with carving. For low power devices I use E27, for power illuminators - E40. Contrary to this, the name of the krushki with other types of socles, such as takiva with a double sole.
DNaT with an E40 base (leaky) and a soffit version with a double outsole
Obviously, in a single external flask, there are two burners. Tova increasing the power for the device, without increasing it significantly, reduce the size, but so easily increasing the efficiency and exploitation of the stomach for the device, for the sake of it, ruin the toplinni.

Sodium lamp with low lampshade
Somehow bleached in a mountain, in addition to the HPS, there is still a little bit of a kind of sodium lighting device:
- DNZ - a reflector is glared, a sector is defined at the top from the top of the knuckle, a light spot on the burner is defined;
DNaZ and its own reflector
- DNaS - scatter on svetlinata.In the composition of the device, the roll on the diffuser on the bright light is made from a special pigment, it is applied on top of the surface on the top of the crown. The spectrum on the DNaS e lampite is similar to that of daylight light;
Somehow, in relation to the emission spectrum, DNaS is decent for a living illuminator DRL
- DNaMT - with a frosted flask. Fully analogous to the DNaS, which is terminated at the moment. Designed for direct substitution on DRL lamps, without any loss of quality for clarification.

Principle for action
Whenever the electrode on the burner was applied, it stored the voltage and at the same time an impulse for high voltage, a spark discharge appeared in the bulb, some soil and dirt were sodium amalgam. Kogato amalgamate is flooded, turning it into a vaporous state, resisting it to a gaseous distance into a kolbata, and gradually discharge it, turning into a flame - lampata flame.
Typically, the time for loading per HPS is 10-15 minutes. In this case, the temperature on the samata burner reached 1200, and on the inside of the burner - 250-300 degrees Celsius. For yes, prevent it from being interrupted by discharges in an uncontrolled arc, ballast it by switching it on in series with the lamp. Under the influence of this on an electric arc, sodium bet will cause and reduce visible light in the yellow-orange spectrum (sodium resonant spectrum). In this case, the light power per device is 150-200 lm / W, depending on the power and type of device.

How to start the HPS lamp
How to use the HPS sodium vapor lamp correctly? Somehow you can see from the mountain, it’s not enough, but apply a safe voltage to the device: the student’s burner has a lot of resistance and just a lot of starter. For yes, it is necessary to start the impulse with a high voltage, and use a special unit - the impulse igniter (IZU).
The trail of a starter on a cruiser, tokt of her trebva and bade is limited. Tova stava through the ballast: electromagnetic or electronic. Parviyat (EMPRA - electromagnetic ballast) e throttle - a reel with an open magnetic chain. Vtoriyat (electronic ballast - electronic ballast) e electronic circuit - current limiter.
Electronic ballast (free) and electronic ballast for HPS illuminators
Throttle all included in series with the crankshaft, IZU - in parallel. Ima 2 kinds of IZU-two-pins and three-pins. Parviyat e-lesen for svarzvane and struva a little, secondly, the work on the verigata is correct. When using the three-terminal IZU by time on the starter, a high-voltage discharge is applied to the lamp itself, and not to the lamp + ballast, as is the case with a device with two terminals. The schematic on the illuminator, using the IZU-type doublet, is shown along the bottom.
Wiring diagrams for a DNaT lamp with two- and three-terminal IZU
Please, pay attention, che nulata and fazata sa jutting out on the diagram. The ballast of wine is included in the phase transition on the conductor. IZU please answer the designations, do not take away the following.
Ignite the device dori imat scheme for tyahnata vrazka.
This is for capacitor C, which is shown in the diagram with a dot and a dash. Not too much, but yama, even put it too much.Tosi capacitor serves to compensate for the reactive power and is known to depend on the efficiency of the verigata. Capacitor trebva even if non-polar charter and even rated for a voltage of at least 400 V. Electrical capacity depends on the power of the lighting device. For DNaT 250 W, 35 μF is sufficient, for DNaT 400 W, increase the capacity to 45 μF.
And one more light. Use your own handkerchief or clean carp to install the HPS clutch. The fact is that the bulb on the device is dirty up to 300 degrees. Give imprints that you will leave on top of the crumble, they will burn out and still form a layer of carbon, which is not good for toplinate. As a result, the comrade was attacked locally and stubbled all over. Somebody or some other evening “caught” a crumble, then I will choose a napkin, moistened with alcohol.

Conditions for izkhvarlyane
The burner for the DNaT lamp contains xenon and an alloy of sodium with a livestock, for some device, it’s not shaking and it’s crazy about kato bitov and otpaddtsi! Burn out the flasks and beat the betrayal at the specialty point for the collection. In addition, the materials for the burner and the grinder, contrary to what is appropriate for ordinary glass, have a completely different chemical composition. Recycling with ordinary glass, quartz and aluminum oxide will simply destroy the stack.
Ima have a lot of space for the izkhvarlyane on devices that eat livestock, but they don’t usually pay attention to them.
According to the current legislation (Decree on the Government of the Ruskata Federation dated 06/05/2011 No.No. 354) excuses for collecting ransacked energy lamps, and for management companies, housing estates, housing cooperatives, etc., and for organizations that support the housing fund. Osventova, in case of failure to fulfill the debt, provide utility services to the right before the globe from a hundred hilyad rubles or more.
Specifications and comparison with analosi
In the evening, the Kazakhs, the HPS type stubbornly hold the position and still use it widely, despite the appearance on the new kind of source in the light. How did you speculate such popularity? Let's compare some of their main characteristics with LED and DRL lamps, which you probably saw in street lamps.
Main features of DNaT, DRL and LED illuminators

From the plate it is clear sevide, consumable 150 W, sodium lamp osiguryava sya svetlinen stream, kato DRL with a power of 250 watts. The only serious competitor for the sodium lamp in relation to the cost-effectiveness of the LED lamp.
But, first of all, LED from a high power sa deset five times a lamp from a lamp. And secondly, the technologat on svrhyarki diodes is not sensible developed, the technologita for production on HPS, which is almost a hundred years old.
Ako add that there is a huge broy of manufacturers on LED products, this is an opportunity, it's a lot of problems to guarantee high-quality semiconductor equipment. What is the praised longevity on the LED, with such a high power of the crystallite barzo it is unloading (they destroy the brightness). In this case, the resource on the diode fence is often becoming less than the resource on the fence with an HPS lamp.
Girth per application
Features a bright spectrum on HPS lids, somehow it turned out, it is ideal for lighting on the streets and highways. For the sake of your spectrum, catch light lines with HPS sabers crawled all over the world before the decade.
It has its own effect against zaglyavane, yellow-orange light line, good visibility on five and not blinding water. For some reason, you can see that sodium lamps are more economical, discharge devices and even more often burn with a pressurized switch, a little strange in fact, than almost 100% of the illumination mains from HPS.
Use on HPS lamps for lighting on streets and highways
For the past few years, the HPS lamp has been partially replaced with LED lamps, but with street lighting, this is often a lot of fun and reluctantly, it is broken off daily.
Hares and radiation spectrum on HPS lampite and plants. Tova define another area on the application on sodium-vapor devices: for lighting on plants in the greenhouse and in places, there is enough sunshine. Probably the greenhouses were waiting, the illumination from the mek was yellow-orange light - the same HPS lamp.

Advantages and disadvantages
Somehow other lighting bodies, lamp with HPS lamps and take advantage of your advantages and disadvantages. Offers include:
- Visoka Svetlinna Efficiency… The difference in the DNaT lamp parameter is that it takes up most of the environment of the gas-discharge lighting device, in spite of the difference on the LED lamp.
- Long exploitation belly… MTBF on HPS lamps reached 15,000 hours. A powerful LED light emitted from the announced brightness is more costly or not much more.
- Comparatively low price... The technology for the production on a lamp is not particularly complex and has been removed for a long time (the HPS lamp is almost 100 years old!), And the device itself does not contain a skype material. In the basin, the LED lighting devices are disastrously tired of sodium - those are the ones to drink by skypi.
- Effect against slander... Yellow-orange spectrum, emitted from HPS lamps, absorbing weakly from water. Dory was in the rain and the darkness was strong, either for brightening or leaving it at a high enough level.
Probably they waited for the farove with yellow glass on colitis - tov safarov for the mist. They use the principle, but the yellow-orange spectrum is not from the lamp, but from the bright filter.
Whatever is lacking, they are very significant:
- Kus color rendering index. HPS lampata is very bright in a narrow yellow-orange spectrum. The bloom on almost the sides of the object in the pelvis is light-colored and strongly curved. It is precisely for the sake of low quality that sodium lamps are absolutely unsuitable for use in residential and industrial premises.
- High ratio on the line... Whenever you use an electromagnetic ballast (throttle), light on the DNaT lamp of an instant from double the frequency to the mrezhata. In this case, the coefficient of pulsation can reach 15-20%. When expounding for a long time on takava light, look at a person who is dead.The problem was completely solved through the use of electronic ballast, but the price is higher than the price of the lamp itself.
- High operating temperature... By the time of operation, the temperature on the DNaT lamp reached 300 degrees, and the control elements (specially throttle) heat up to 100 degrees. Tova is not just a flash with serious burns in case of accidental cutting, but it is such a special measure for fire safety.
- Difficulty starting at low temperatures… Due to its design characteristics, HPS lamps are difficult to start at low temperatures in some environments. Tosi problems are partially solved through the use of an external clutch with a vacuum, but despite the fact that the lamp is strong, it may not be a starter. For the sake of the Tazi, the reason for the use of HPS lamps in the far north is not a problem.
- Long time on the trap... The trace of the inclusion of the lamp barely shines and gradually the flame itself, as soon as the burner was flooded. After reaching the operating mode, the HPS lamp will need from 10-15 minutes. The lamp is burning, somehow the current is turned off, nyama and the starter of the vednaga: first, cool trebva and then cool it, and then turn it on again and flame.
You can use this information for a sodium lamp with a high pressure. Now you know how the device works, for what good and for what lack. And how do you decide and organize your own clarification with the help of HPS lamps, then you can read the trace of this article, or you can choose a control device and turn the lamp on it without external help.
