Low-voltage halogen lamps ........................... P. 12
Because of their superiortechnology and excellent economy, low-voltage halogenlamps are among the most important lamps for traffic signalling equipment. Theselamps have been developedover the past few years tosuch an extent that their lifehas doubled. Now they onlyneed replacing on a two-yearcycle (life of around 16,000hours).
This has been made possibleby the various known benefitsof low-voltage design but inparticular by halogen techno-logy. The halogen cycle meansthat the life of the lamp can besignificantly increased whileretaining almost constant luminous flux over the entire life of the lamp.

Display and signal lamps and lamps for traffic light installations.Lamps that set standards.
Road and rail traffic light in-stallations are crucial to safety,which is why the lamps usedin these installations have tomeet such high demands. Reliability is obviously thenumber one priority. Economyalso has an important role toplay. These two factors are influenced to a large extent bythe quality of the lamps used.OSRAM offers a range oflamps that sets standards interms of safety and also interms of economy.
You can rely on renowned OSRAM quality to provide thefollowing, to name a few:– High luminous flux for good
signalling effect even in difficult weather conditions
– Precise lamp alignment and shape for correct luminous intensity distribution
– Standardised high-quality bases that enable lamps to be replaced without the need for realignment even after many hours of operation
– Low maintenance costs thanks to long lamp life
– Low power consumption thanks to high luminous efficacy.
The existing range will bemaintained and further developed to meet changingcustomer requirements. LONGLIFE versions are nowavailable in almost all signallamp groups.

Low-voltage overpressurelamps ...................... P. 14/18
10V technology has becomethe established technology inmodern traffic light installa-tions, and for good reason.Low-voltage overpressure signal lamps have a much higher luminous efficacy thanmains voltage signal lamps.This means that low-voltageoverpressure lamps with sig-nificantly lower wattages canoften be used, with a resultantreduction in the power con-sumption of the signallingequipment. This lamp techno-
logy is also used in rail traffic light installations (see p. 18).Existing 230V signal installa-tions can be converted to 10Vsystems by replacing the lampand the reflector and installinga transformer. OSRAM has also developed LONGLIFEversions of low-voltage over-pressure lamps. By using thenew LONGLIFE low-voltageoverpressure lamps it is possi-ble to extend the maintenancecycle to a maximum of oneyear.
Signal lamps for mains voltage ......................... P. 16
Most traffic light installationsthroughout Europe are stilloperated on mains voltage.OSRAM has therefore devel-oped the tried and trustedstandard and krypton signallamps into LONGLIFE signallamps. These can be used as direct replacements for existing standard and kryptonlamps without having to modify the installations in anyway. Maintenance cycles areconsiderably extended as a result. Depending on the
installation, maintenance cycles of up to eight monthsare possible, which help enormously in reducing maintenance costs.

OSRAM signal lamps for roadand rail traffic light installa-tions are precision lamps whichare manufactured in largenumbers. A comprehensiverange of quality assurancemeasures during manufactureensures that these lamps areof consistently high quality.
Users are interested only inthe period of time in which thelamps can be used economi-cally. In other words they arelooking for the maximum pos-sible time in which the inevi-table early failures remain below a certain threshold. This period of time differs fromone type of lamp to anotherand is defined as the individ-ual lamp life:
Individual lamp life: The timeduring which a lamp remainsfunctional when tested understandard operating conditions(see DIN 49842 Part 3).
Individual lamp life up to afailure rate of x%: The periodof time during which x% of thelamps reach the end of theirindividual lamp life (see [1] inthe graph).
Example: In the case of LONGLIFE mains voltage signal lamps, the failure rate in the first 5,500 hours of operation is no more than 2%.
Lamp life
Average lamp life: This is thearithmetic average of all indi-vidual lamp lives of a numberof lamps tested under stan-dard operating conditions (see[2] in the graph).
Example: In the case of LONGLIFE mains voltage signal lamps, the failure rate in the first 14,000 hours ofoperation is no more than50%.
In most cases it is uneconomi-cal to exploit the full averagelamp life since individual re-placement costs are often outof proportion to lamp costs.
OSRAM builds on quality
The technical conditions ofsupply specified for the individ-ual lamp categories containadditional technical informa-tion on limit values, test con-ditions and references to the“Acceptable Quality Levels(AQL values)” based on the rules of statistical quality con-trol and in accordance withthe guidelines of the DeutscheGesellschaft für Qualität e. V.(German Quality Society)(DGQ). The technical condi-tions of supply are availablefrom OSRAM on request. Theentire manufacturing processat OSRAM is accompanied bya comprehensive system oftests and inspections. Qualityassurance begins at the devel-opment stage and with thepurchase of raw materials andcontinues through all stages of production up to final in-spection and dispatch to thecustomer. OSRAM developsand manufactures in com-pliance with the requirementsof the ISO 9001 standard.

When an incandescent lamp is operated at voltages withina given range the characteris-tics of the lamp will changeexponentially compared withits characteristics at rated voltage. The relative changesfor gas filled incandescentlamps as the operating volt-age deviate from the rated voltage are shown for the following characteristics (Fig. 1):
– Luminous flux Ø– Luminous efficacy n– Electrical power P– Lamp current l– Colour temperature Tf, Tn
– Lamp life L
Note that the lamps becomeless and less economical asthe voltage drops. The rela-tionship between power consumed and luminous fluxproduced gets progressivelyworse.
The theoretical average lamplife is of no significance in actual practice. Because ofthe changes that take placewithin the lamp due to thephysical processes involved,especially in the filament wire,any theoretical increase inlamp life cannot be achievedin practice. In particular, theproportion of early failures isnot reduced by any significantamount.
The tungsten halogen cycle is such that it operates most effectively at rated voltage.For this reason, the expectedincrease in lamp life in the range between 90 and 95% of rated voltage is not as highas with standard incandescentlamps (low-voltage over-pressure) (Fig. 2).

With its extensive product range, OSRAM offers manydifferent ways of reducing theoperating costs of signallinginstallations. In particular, considerable reductions inoperating costs can be achieved by using low-volt-age halogen lamps.
The elements that make upoperating costs for signallinginstallations are shown in Table 1.
Existing mains voltage signalinstallations can be convertedto low-voltage systems by replacing the lamps and re-flectors and installing a trans-former. Using low-voltage halogen lamps instead ofstandard mains voltage signallamps can reduce operatingcosts by up to 80% (= 114,000 €).

Soiling of the internal and external surfaces of the sig-nalling optics is a major con-tributor to the loss of luminousintensity. Measurements havebeen taken on signallingequipment over a long periodof time. The diagrams belowshow the luminous intensitydistributions as an average ofall the measurements.
In this connection, note alsothe following from DIN 67527Part 1 Section 6 – Mainte-nance: “Cleaning and main-tenance should be carried out at intervals so that the minimum values* indicated in DIN EN 12368:2000-03, Table 1 are not undershot bymore than 20%. As a generalrule, it is more economical to carry out maintenance work at fixed intervals when all the lamps can be replacedand the signal lights cleaned.”* (for the luminous intensity)

Lamp technology: Loss of luminous flux due to bulb blackening
Fig. 4: Residual luminous flux for different signal lamps (HV/NV/HAL)
Fig. 3: Halogen lamp with halogen cycle
Fig. 2: Gas-filled lamp showing lamp life as a function of cold filler pressure and type of gas
Fig. 1: Vacuum lamps with tungsten vaporisation rate
To achieve a high level of optical efficiency (luminous efficacy) from an incandescentlamp the filament temperaturehas to be as high as possible.There are, however, limits tothe extent to which the fila-ment temperature can be raised as the rate at whichtungsten vaporises increasesrapidly as the temperature rises. The life of incandescentlamps is therefore reducedconsiderably as the filamenttemperature rises. What’s more, the vaporised tungstenatoms condense on the lampbulb, which produces a blackdeposit. This in turn results inloss of light due to absorption(Fig. 1). Ultimately, this meansthat the lamp has to be re-placed in order to comply withthe minimum values for lu-minous intensity.
Compared with a vacuumlamp (e. g. HV Standard) thevaporisation rate and thereforebulb blackening can be greatlyreduced by adding an inertgas (N2, Ar, Kr, Xe). As a resultof adding inert gas and the associated option of varyingthe filler pressure, the filamenttemperature can be increased,which in turn increases the luminous efficacy. With mainsvoltage krypton lamps, opticalefficiency can therefore be raised by as much as 60%compared with standard mainsvoltage lamps.
On the other hand, there is also the possibility of keepingthe filament temperature thesame and using inert gases toprolong the life of the lamps.The possible increases in lamplife depend to a large extenton the inert gas used (Fig. 2).The most effective inert gasesare very expensive however,so for reasons of economythere is no point in using thesegases for large bulb volumesand high filler pressures.
Bulb blackening was only effectively prevented with thedevelopment of the halogencycle (Fig. 3). The halogen cycle has reduced loss of lu-minous flux over the life of the lamp to such an extentthat signal lamps with verylong lives can now be pro-duced (Fig. 4). It has also enabled lamps with very com-pact bulb dimensions to bedeveloped. These small bulbvolumes make it economicallyviable to use expensive inertgases such as krypton and xenon at high filler pressures.This considerably reduces thevaporisation rate of tungsten,which in turn prolongs the life of the lamps comparedwith conventional low-voltagelamps.

DIN-compliant operation
There is no disputing that sig-nalling installations that do notfunction properly constitute areal danger. Local authoritiesare under enormous financialpressure to make savingswherever they can. There is therefore a risk that main-tenance intervals for trafficlights will be extended be-yond the values prescribed inthe relevant standards.
The technical aspects and theresultant problems are oftenunderestimated, particularlythe consequences of morestringent product liability andthe duty of care towards roadusers. There is a risk of person-al liability if signalling instal-lations are not operated in accordance with the relevantstandards or if signal lampsthat do not comply with thesestandards are used.
Although DIN standards arenot laws of a binding charac-ter for the actual design of thesignalling installations, they dodefine the current productspecifications and are used bycourts of law to establish theappropriate safety levels forroad users and therefore thenature of the liability.
The most important informa-tion and data for road trafficlight installations and asso-ciated lamps are summarisedin the following standards:

Halogen signal lamps for10V technology
Thanks to continual improve-ments, low-voltage halogenlamps now offer an excellentset of properties. Superior tech-nology and high production
quality combine to enable thelamps to be replaced on atwo-year cycle (lamp life ofaround 16,000 hours) for amaximum premature failurerate of 2% 3), which saves onmaintenance costs. Other benefits include high resis-
tance to shocks and vibrationsand a very high luminous effi-cacy that remains almost con-stant throughout the life of thelamp as halogen technologyprevents the bulb from black-ening. Their geometry, lumi-nous flux and electronic data
comply with existing stan-dards (DIN 49842 Parts 1 and 3), which means theselamps can be used in existinginstallations without the needfor upgrades or adjustments.
These low-voltage tungsten-halogen lampsare available for signal-ling equipment designedfor lamp supply voltagesof 10 or 12 V

Operating instructions
All halogen signal lamps operate at high temperatureand pressure. They may therefore only be operated insignal equipment/luminairesspecially designed for the purpose. Make sure that thelamps are protected againstmoisture during operation and in particular during relamp-ing. When installing a newlamp, handle it by its protec-tive cardboard sleeve.

Low-voltage overpressurelamps for 10V systems
Low-voltage overpressure signal lamps have a much higher luminous efficacy thanhigh-voltage signal lamps.This is due to the higher gaspressure and the inert fillergas. The larger diameter of the tungsten wire of the low-voltage filament also helps increase efficiency. This means that low-voltage over-pressure lamps with signifi-cantly lower wattages can often be used, with a resultantreduction in the power con-sumption of the signallingequipment. The filament wireis more stable than in the HV lamp, which means thatresistance to shocks and vibration is particularly high.
The failure rate for standard 10V low-voltage overpressurelamps is less than 2% withinthe first 4,400 hours of opera-tion1).
Lamps for road traffic signalling equipment
These benefits can also be putto use in existing 230V signal-ling installations as it is pos-sible to convert mains voltageinstallations to 10V technol-ogy. The lamp and reflectorhave to be replaced and atransformer installed.
Low-voltage LONGLIFElamps for 10V systems
The old low-voltage signallamp has now been further developed into a LONGLIFElamp. With these lamps, a failure rate of 2% is not exceeded in the first 8,000hours1). With these lamps therefore the maintenance interval may be up to one year(depending on the installation).
1) The premature failure rate is restricted to cases that are due to lamp faults and not to external influences
2) Lamps with transverse filaments should only be inclined perpendicular to the filament plane
3) The lamps must be installed only in the burning positions specified. Any other burning positions will lead to premature failure of the lamp. The abbreviations indicate the main burning position and the permitted angle in degrees. Main burning positions: s = standing (vertical), base down
4) LCL = light centre length (distance from the coil to top of base)
This means that the advantages of low-voltage technology are now available in mains voltage installations
Compared with high-voltage lamps, low-voltage overpressuresignal lamps have aconsiderably higher luminous efficacy. Thisis due to the higher gaspressure and the inertfiller gas

Low-voltage overpressurelamps for 40V systems
The average lamp life is 8,000 hours. The lamps com-ply with DIN 49842 Parts 1and 3. The failure rate is lessthan 2% within the first 3,000 hours of operation1). Inother words, maintenance intervals will be around fourmonths (depending on the in-stallation).
Dual-coil lamps
The operational reliability ofdual-coil lamps is much higherthan that of single-coil lamps.If the main filament fails, it ispossible to switch to the sec-ondary filament. Availability of the installation is thereforeincreased. For safety reasons,however, it is recommendedthat the lamp be replaced as soon as possible. The dual-coil lamp is used mainlyfor the red signal.

1) The premature failure rate is restricted to cases that are due to lamp faults and not to external influences
2) Lamps with transverse filaments should only be inclined perpendicular to the filament plane
3) The lamps must be installed only in the burning positions specified. Any other burning positions will lead to premature failure of the lamp. The abbreviations indicate the main burning position and the permitted angle in degrees. Main burning positions: s = standing (vertical), base down
4) LCL = light centre length (distance from the coil to top of base)
The compact coil ensures a high level of optical efficiency and a high axialluminous intensity; the inert gas fillingensures impressive economy

High-voltage krypton lamps
The majority of road trafficlight installations are still operated on a voltage of 220to 240V. For these systems,special lamps have been developed which meet thehigh requirements demandedof the signal optics. Mains voltage signal lamps are de-signed for an average lamp life
Lamps for road traffic signalling equipment
of 8,000 hours. However, thisis in no way an indication oftheir useful service life. Theyardstick for useful service lifeis the “individual lamp life” orpremature failure rate. In thecase of mains voltage signallamps, the failure rate in thefirst 3,000 hours of operation is no more than 2%1). In otherwords, maintenance intervalswill be around four months
(depending on the installation).The krypton inert-gas lampsconform to the specificationsof DIN 49842, Parts 2 and 3.This means that in modernsignal lights the luminous intensity values laid down in DIN 67527 Part 1 and DIN EN 12368 are met.

Mains voltage krypton lamps are used in systems that comply with DIN 67527, Part 1, and EN 12368
The advantages of high-voltage krypton lamps are asfollows:– Excellent optical efficiency
thanks to a small cradle diameter
– High luminous efficacy from krypton as the filler gas
– High resistance to shock and vibrations thanks to the nine supports for the filament
Mains voltage LONGLIFEkrypton lamps
We have managed to improveour tried and trusted mainsvoltage lamp technology evenfurther. Maintenance cyclesare longer with the new
LONGLIFE signal lamps. Depending on the system, these cycles may be up to eightmonths. Average lamp life is14,000 hours. Within the first5,500 hours of operation therewill be no more than 2% lampfailures1). The rated luminous
intensities defined in EN 12368 are achieved at allwattage levels. LONGLIFElamps correspond completelyto the successful standard series in their technical design,gas filler, E 27 base and un-changed light centre length.
They can therefore be used inexisting mains voltage signalswithout the need for upgradesor adjustments.

Single-filament lamps
Safety on the railways calls forreliable signalling equipment.Defective lamps pose a serious risk, cause expensivedelays to train schedules and lead to costly and time-consuming maintenance work because of the large distances between signals.OSRAM has played a majorrole over many years in en-suring that railways have operated at high levels of safety and efficiency. The advantages of OSRAM lampsare as follows:– Narrow tolerances– Exact light centre– Long lamp life– High reliability
Extremely strict quality controls ensure compliancewith tight geometrical tol-erances, photometric valuesand specified life. The variouswattages of the normal andoverpressure types (= ref-erence “Ü”) are matched to the specific needs of the relevant optical systems.

Doubly safe: the second coil takes over from the main coil if the main coil fails
Dual-filament lamps
All dual-filament lamps arenow manufactured as over-pressure lamps. The secondfilament takes over from themain filament if the main filament fails. Changeovermay be manual or automatic.This provides a certain safetymargin for rail traffic until thelamp is replaced. For safetyreasons, however, it is recom-mended that the lamp be replaced as soon as possible.The various wattages are matched to the specific needsof the relevant optical sys-tems.
