34、en-sity of high intensity discharge and incandescentindoor-type luminaires. All mercury, high-pressuresodium (HPS), and metal halide lamps are classifiedas High Intensity Discharge (HID) lamps, and theirphotometry when installed in indoor-type luminairesis covered by this method. Also covered are si
35、milarluminaire types employing incandescent lamps,including tungsten-halogen lamps. For the uniquetesting requirements of entertainment lighting lumi-naires (stage, TV, film) using HID and incandescentlamps, consult LM-73-04, IESNA Guide forPhotometric Testing of Entertainment LightingLuminaires Usi
36、ng Incandescent Filament Lamps orHigh-Intensity Discharge Lamps.2Because of theirspecial characteristics, low-pressure sodium lampsand fluorescent lamps are not discussed in these pro-cedures. For information on low pressure sodium andfluorescent lamp testing, consult LM-59-00, IESNAApproved Method
37、for Electrical and PhotometricMeasurements of Low Pressure Sodium Lamps3andLM-41-98, Approved Method for Photometric Testingof Indoor Fluorescent Luminaires.42.0 SELECTION OF LAMPSThe lamps selected shall conform to the lamp manu-facturers nominal design dimensions and parame-ters. Lamps with phosph
38、or coatings shall be carefullyselected to obtain a phosphor density uniform overthe entire lamp envelope. It is important to ensure thatthe centering of the arc tube and other mechanicaldetails are within the limits recommended by theAmerican National Standards Institute (ANSI).53.0 SELECTION OF LUM
39、INAIRESEach luminaire selected should be representative ofthe manufacturers typical product.The luminaire shallbe clean, except in cases where dirt depreciationmeasurements are the reason for the photometry.Precise location of the lamp within the luminaire canbe extremely important, particularly in
40、the case ofbeam forming equipment.4.0 TEST CONDITIONS4.1 Extraneous LightExtraneous light is any light that reaches the pho-todetector other than directly (or reflected from themirror, for a moving mirror photometer) from thesource being measured because of extraneousreflections or other light sourc
41、es. Adequate precau-tions shall be taken to minimize such reflections byusing flat black surfaces and by using angles,grooves, baffles, and other light traps.Extraneous light can be measured by running a com-plete or partial test with the direct light from the lumi-naire completely shielded from the
42、 photodetector.Thephotodetector then sees only extraneous light whichcan be measured, recorded, and then subtracted dur-ing the calculation of the luminaire luminous intensi-ties. Care must be taken to block only direct light whilesimultaneously providing minimal interference toextraneous light path
43、s.4.2 Ambient TemperatureFor precise measurement of photometric and electri-cal characteristics of luminaires with HID and incan-descent lamps, the ambient temperature should bemaintained at 25C 5C (77F 9F). This tempera-ture shall be measured at a point not more than 1.5meters (5 feet) from the lam
44、p or luminaire and at thesame height as the lamp or luminaire. The tempera-ture-sensing device shall be shielded from direct radi-ation of the light source. Deviations from the recom-mended temperature specifications shall be noted inthe report.4.3 Air MovementThe luminaire (or test lamp during cali
45、bration) shall betested in relatively still air. A maximum airflow of 0.08meters/second (15 ft./minute) is suggested.1IESNA LM-46-044.4 Lamp SeasoningTest lamps shall be seasoned such that their charac-teristics remain constant during the test to be con-ducted. See reference 6, LM-54-99, IESNA Guide
46、 toLamp Seasoning, for detailed information.4.5 Test Lamp OperationAccurate measurements of light require that the lampbe operated on the proper electrical circuits as out-lined in the pertinent ANSI standards. Stable perfor-mance is of primary importance. The lamp is consid-ered stabilized when the
47、 monitoring of light outputover a period of 30 minutes produces fluctuations nogreater than 1.0 percent between any two consecu-tive readings taken approximately 15 minutes apart.Care must be taken to be sure the successive lightreadings are not increasing or decreasing monotoni-cally. A false sense
48、 of stabilization can occur if thesampling period is short compared to the normallamp stabilization time. A stabilization time of ten min-utes is usually sufficient for incandescent and tung-sten-halogen lamps, but may range from one to threehours for mercury, HPS, and metal halide lamps.HID lamps o
49、perating on magnetic ballasts shall beoperated within 2.0 percent of the rated power of thelamp. HID lamps operating on electronic ballasts shallhave the ballast input voltage set to within 0.5 per-cent of the units rated primary voltage, and if the volt-age is a range, the nominal voltage should be usedand indicated on the test report.Tungsten-halogen lamps must be operated at a con-stant value of current near their nominal voltage.Other incandescent filament lamps may be operatedat a constant current that corresponds to 90 percent of rated input lamp voltage (this prac
