24、LMCO RP-36-151IES/NALMCO RP-36-151.0 INTRODUCTIONAll electric lighting systems degrade in performance during their operating life. Lamps produce less and less light the longer they operate, while their spec-tral output may shift in color. Lamp output may be absorbed by dirt and dust accumulation on

25、luminaire surfaces. Light distribution may be distorted by dirt and dust and/or degradation of luminaire surfaces. Components fail over time. If left unchecked, ongoing loss of illuminance and disruption to uniformity will continue until the lighting system ceases to function.Although automatic ligh

26、ting controls are specified increasingly in commercial buildings as a manda-tory energy-saving measure, they should be properly designed, installed and calibrated to save energy. Over time, space layout, user needs or occupancy patterns may change, resulting in misalignment between control operation

27、 and how the space is used. If users are dissatisfied, they may seek to over-ride the controls, potentially negating energy savings.To ensure continuing operations, owners take actions to preserve the functionality of their lighting systems, which we call maintenance. Well-maintained lighting system

28、s function in a predictable manner while offer-ing the potential for capital and operating cost sav-ings. Poorly maintained lighting systems may suffer from low illuminance and unaddressed outages, non-uniform light distribution, color shift, improperly aimed luminaires, mismatched components, cycli

29、ng lamps, early component failure and other problems. This may translate to problems with user satis-faction, productivity, aesthetics, sales, safety and security, and the ability to capture intended energy savings on an ongoing basis.How a lighting system will be maintained is impor-tant informatio

30、n for lighting designers, just as design information is important for maintenance personnel. Since the maintenance method influences the extent of expected light loss, it also relates to the amount of lumen output needed to maintain the required illu-minance. In other words, if a well-maintained lig

31、hting system will result in a higher maintained illuminance, then fewer lumens are needed to produce the design level, which may translate to fewer lamps and/or luminaires. This will reduce capital and energy costs.Designers, meanwhile, should design lighting sys-tems that are easy to maintain, spec

32、ify commis-sioning criteria or expectations when possible, and ensure maintenance personnel are properly trained and given a complete system manual upon turnover. Easy-to-maintain lighting systems feature readily accessible, long-life components within designs in which the luminaires are similarly a

33、ccessible without excessive difficulty or cost. Commissioning ensures that the initial installed system is verified as satisfy-ing owner project requirements. Maintenance per-sonnel should be trained on the proper operation and maintenance of the lighting system, and have all appropriate documentati

34、on on hand regarding the finished design and how to maintain it, includ-ing owner project requirements, design intent, final drawings, schedule of installed components and systems, device settings, lighting control sequence of operations and recommended maintenance plan.Robust maintenance requires m

35、ore attention and resources and therefore benefits from planning. Planned maintenance involves scheduling opera-tions and maintaining the lighting system with the most time- and cost-efficient use of labor and resources, utilizing techniques such as periodic inspection, group relamping and luminaire

36、 clean-ing. All components in the lighting system (con-trols, power supplies, sensors, for example) are documented so that they are properly maintained. The design itself is documented and understood by maintenance personnel so that operations are undertaken to maintain the original design intent, n

37、ot just the equipment in the system.As lighting systems become increasingly complex, properly maintaining them requires more resources, expertise and competence. Often, it is desirable for the owner to use a lighting management company and trained staff. Such companies are represented within the lig

38、hting industry by the interNational Association of Lighting Management Companies (NALMCO). Its members professionalism, experience and lighting expertise are recognized by the Associations Certified Lighting Management Consultant (CLMC), Certified Senior Lighting Technician (CSLT) and Certified Appr

39、entice Lighting Technician (CALT) certifications.This Recommended Practice examines common lighting maintenance procedures and the central components of an effective planned maintenance program. Specifically, it describes: typical lighting system behavior, identifying those light loss factors that c

40、an be addressed by maintenance; maintenance approaches that can optimize lighting system performance; ways in which designers should address maintenance; typical maintenance techniques, equipment and operations;2IES/NALMCO RP-36-15 proper disposal of spent components; and troubleshooting system prob

41、lems.Lighting designers and specifiers can use this Recommended Practice to design lighting systems that will be easy to maintain and optimize energy efficiency and maintenance based on good main-tenance practices and careful product selection. They will also be able to recommend good main-tenance p

42、ractices. Facility owners and managers can use it to develop a maintenance plan and prop-erly maintain their lighting systems to ensure their investment in light performs in accordance with requirements far into the future. Other electrical and lighting professionals can use the Recommend Practice i

43、n the roles they play in recommending, specifying, installing, commissioning and maintain-ing lighting systems.2.0 FAILURE MODESLamps that are past their useful life should be replaced as soon as is practical. Mortality is only one indicator of useful life expiration. Some lamps may continue operati

44、on for long periods but exhibit performance deterioration that renders continued use uneconomical or impractical.For purposes of lighting system maintenance, it may be practical to consider a lamp as expired if: it no longer produces light even though a known good lamp in the same socket lights up n

45、ormally (lamp failure); its lumen output depreciates to an unacceptably low value based on observation or as predicted via manufacturers lamp lumen depreciation curves; the lamp has experienced significant color shift, stands out visually from other lamps, and compromises the sites design intent; or

46、 the lamp produces fluctuating output so as to be visually disturbing or annoying.Other components of the lighting system, including auxiliary devices (i.e., ballasts, transformers, drivers, or generators), sockets, wiring, and the luminaire itself, may also cause a failure to produce illumination o

47、r suf-ficient illumination, and will require corrective action.2.1 Lamp MortalityWhile some new lamps (and auxiliary devices used to operate them) may fail upon or shortly after instal-lation due to manufacturing defects, the large major-ity will fail during operation.A large group of lamps of the s

48、ame type will fail in a predictable manner (see Figure 1). For most lamps, rated lamp life is based on this curve. For fluorescent and metal halide lamps, for example, rated life is defined as when half of a large group of lamps can Figure 1: This typical lamp mortality curve shows the percent of a

49、group of lamps that survive after operating for a period of time. The different lines are used to suggest considerable variation between different lamp technologies. Traditional technologies have “life” rated as a B50 rating which is the point at which 50 percent of the initial group will have “died.” (Graph courtesy of Sri Rahm)3IES/NALMCO RP-36-15be expected to have failed (the median). For mer-cury vapor and high-pressure sodium high-intensity discharge (HID) lamps, rated life occurs when 17-40 percent of a large group of lamps is expected to have failed; the specific percen
