IntroductionWho is Philips? Royal Philips Electronicsof the Netherlands is one of theworld’s largest electronics companies,with sales in 2002 of US $28 billion; itemploys nearly 164,000 people in over60 countries. The foundations for whatwas to become the world’s largest lightingcompany were laid in 1891 whenGerard Philips established a company inEindhoven, the Netherlands, to “manufactureincandescent lamps and otherelectrical products.”Royal Philips Electronics is tenth onFortune’s list of global top electronicscorporations. We are active in about 60businesses, varying from consumer electronicsto domestic appliances, and fromsecurity systems to semiconductors toCompact Disc players to lighting.Check this out:As one of the world’s largest lightingcompanies – Philips produces over 2.4billion incandescent lamps every year.That’s over 2,400,000,000 bulbs!

Incandescent OperationIn an incandescent bulb, a tungstenfilament is heated by an electric currentuntil the filament becomes incandescentor gives off light. The intense heat causesthe tungsten filament to slowly evaporate.This filament evaporation causes twothings to happen. First, it causes the bulbto get blackened over time. The blackeningof the bulb causes the bulb to becomeslightly dimmer over time. Second, as thefilament evaporates, it gets thinner andthinner until finally it gets so thin, it breaksand the bulb fails. This is the normal endof life for an incandescent bulb.The life of a bulb depends on the thickness of the tungstenfilament, a thick filament will last longer than a thin one. But athick filament does not get as hot so it produces less light. That’sthe trade-off—if you want more life, you get less light and viceversa.A standard bulb’s life is 750–1000 hours and longer lifebulbs last 1000–1250 hours.People often ask what causes a bulb to burn out prematurely.One reason is over-voltage. If an incandescent bulb is subjectedto a higher than rated voltage or even a surge or spike, it willcause the filament to overheat and it will evaporate at a muchfaster rate, the result—short life. Another reason for short lifeis shock and vibration. If the bulb’s filament is not a rough servicedesign with filament supports, shock and vibration may shortenits life.4 Product Knowledge


Halogen OperationReflectorHalogen CapsuleCut-away view ofa PAR38 HalogenHalogen Bulbs are technically incandescent bulbs, butthey have three features that make them superior tostandard incandescent.They are Brighter, Whiter, and Last Longer.A Halogen lamp has a thin filament. A thin filament producesmore light than a thick one. This makes it brighter and whiter.But how does it last longer with a thin filament? The answer is…The Halogen CycleThe filament is in a glass capsule. The glass capsule containsan incandescent bulb, but before the tungsten deposits onthe bulb wall, the halogen gas transports it back to thefilament—replenishing it and keeping the bulb clean and bright.The halogen gas actually regenerates the filament. This is whyHalogen bulbs last much longer and stay bright throughout theirlife. However, the tungsten does not go back exactly to the samespot on the filament, so eventually it gets weak at one point andfails, ending the cycle.VoltageHalogen lamps are available for low-voltage operation (for whicha transformer is needed) or for 120 volt as direct replacementsfor incandescent lamps.Lighting A–Z 5


Incandescent Lamp PartsFilamentGlass BulbFilament SupportLead-InWiresGas or VacuumBaseFuseFilamentCoil of tungsten wire. Tungsten is used because it has the highestmelting point of any metal.Lead-In WiresConduct the current from the base through the glass bulb tothe filament. The part exposed to the inert gas is made of nickel.The part embedded in the glass is made of dumet and the partconnected to the base is made of copper.Filament SupportThis part protects the filament from shock and vibration.Glass BulbPrevents oxygen from attacking or oxidizing the filament. Theglass bulb will contain a vacuum or an inert gas.Gas or VacuumInert gas contained in the bulb is usually a mixture of nitrogenand argon. Krypton is also used. A vacuum is used in lowwattage bulbs.BaseProvides a means of connecting the bulb to the socket. Bases aremade of aluminum or brass. Brass bases are anti-corrosive. Thebases are attached to the bulb with basing cement.FuseUsually an arc forms when the filament fails which could tripthe circuit breaker in the lighting circuit. The fuse prevents thefilament from drawing excess current when it fails.6 Product Knowledge

Philipsbulbs contain an exclusive electrode guard that minimizes endblackening (shown on page 28).Phosphor CoatingPhosphor coating on the bulb wall converts ultraviolet energyto visible light in a process called fluorescence. Newer, moreexpensive phosphor coatings are used on bulbs with high colorrendering and higher light output.Lighting A–Z 19


Fluorescent Lamp OperationGlass bulbVisible LightPhosphor Crystals2.3.Electrode1.MercuryOperationWhen started, the electrodes at each end of the lamp emitelectrons.1. The electrons travel through the tube in the form of anelectrical current. The electrons collide with the mercuryatoms contained in the glass bulb.2. After the collision, the mercury atom releases invisibleultraviolet energy.3. The ultraviolet energy strikes the phosphor coating and thephosphor converts the ultraviolet to visible light.BallastAll fluorescent lamps need a ballast to operate properly. Theballast provides the proper starting voltage and limits thecurrent through the lamp. It is important to have the correctballast for proper operation. The ballast label has importantinformation such as which lamps the ballast will operate and awiring diagram.20 Product Knowledge

High Intensity Discharge (HID)Mercury vapor, MetalHalide and HighPressure Sodiumcomprise the familyof High IntensityDischarge lamps (HID).In HID lamps, light isproduced by passingan electric currentthrough a gas or vaporat high pressure. Thecurrent produces ahigh intensity arc ordischarge of light thatis very efficient and hasa longer life.Common Characteristics of HID Lamps All HID lamps have a warm-up period that lasts from 3–10minutes (depending on the type and wattage) before itproduces full light output. It is important that an HID lamp have correct ballast tooperate properly (compare ANSI code on ballast andlamp package). HID lamps have a restrike time which ranges from1–15 minutes depending on type and wattage.Lighting A–Z 29

National Energy Policy Act(EPACT)Signed into law October 24, 1992 by President Bush, theNational Energy Policy Act (EPACT) is designed to reduce thenation’s energy bill by some $250 billion over 15 years. Energyused for lighting, the primary focus of the bill, could be slashedup to 50%, reducing the national electricity usage by 10%.EPACT mandates energy efficiency standards for lamps in termsof efficacy, measured in lumens per watt (LPW), and colorrendering index (CRI), the ability of a light source to rendercolors accurately. EPACT has established minimum LPW andCRI standards, which has eliminated those fluorescent andincandescent lamps that provide the least amount of light forthe highest use of energy. This has affected some full wattage 4-foot, 2-foot U-Bent, 8-foot Slimline, and 8-foot high-output lamps.Lamps with a very good CRI and special service fluorescentlamps have been excluded from the Act.Due to the high CRI of incandescent lamps (100), stringentefficacy standards have been set. These standards have eliminatedmany popular R and PAR types, including the R-30, R-40 andPAR-38. Lamps with a diameter of less than 2.75 inches, suchas the R20 and PAR-16, are exempt from the Act, as are ERand BR lamps.New information required on packaging and product literaturewill help you compare products. The information includeslumen output, estimated efficiency (lumens per watt) and lamplife. Fluorescents packaging will also list Color Rendering Index.Although they are exempt from efficiency standards, A-lampsand compact fluorescents must be labeled. The information canhelp you compare light output and pick the appropriate lamp forthe job while reducing lighting energy usage.Lighting A–Z 41
