22、 pressure sodium lamps. The electrical data provides the specific basis for ballast requirements for these lamps. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard.

28、assigned in accordance with ANSI C78.380. For reference, the older designations are shown in parentheses in the lamp data sheets. Note that the number (two or three digits) following the first letter in the designation (L for low pressure sodium), indicates a unique set of electrical characteristics
29、. After the number is a slash followed by a luminaire characteristic letter. Low pressure sodium lamps are typically used in enclosed luminaires and have a luminaire characteristic code of “E”. Marking Low Pressure Sodium Lamps with the ANSI designation is not required. 4 Bulb Designations Bulb desi
30、gnations are defined in ANSI C79.1. Due to the long term use of the conventional method of bulb designations, their use will continue herein with the equivalent metric bulb designations shown in parentheses (i.e. BT28 BT90 ) in contrast with the use of metric primary dimensions elsewhere in this sta
31、ndard. 5 Base specifications The BY22d base is described in ANSI_ANSLG C81.61. 6 Maximum outline drawings The maximum outline drawings in Chapter III of this standard show the maximum limits of the space that may be occupied by any part of the bulb for each lamp type. These limits are in accordance
32、with IEC 60192. Most luminaires for low pressure sodium lamps constrain the dome end of the lamp and take up any eccentricity of the lamp by means of a moveable base holder. Accordingly, the maximum outline drawings allow for the maximum bulb diameter at the dome end and for eccentricity at the base
33、 end. 7 Other safety requirements and information Lamps shall comply with the requirements of ANSI_IEC C78.62035. Low Pressure Sodium lamps contain a quantity of Sodium that may heat from a reaction with moisture in the air or on the skin if the lamp is broken. Sodium may burn spontaneously when exp
34、osed to air. Consult the lamp manufacturers literature for information on the proper use, care, and disposal of these lamps. 8 Methods of measurement An American National Standard for methods of measuring the electrical characteristics and the bulb and base temperatures of low pressure sodium lamps
35、has not been written. General guidelines for these measurements may be found in ANSI C78.389 and IEC 60192. Copyright 2006 by American National Standard Lighting Group 6ANSI_ANSLG C78.41-2006 Revision of ANSI C78.41-2001 9 Electrical characteristics 9.1 Lamp operating characteristics. The values of
36、lamp volts, amperes, and watts shown on the individual lamp data sheets in Part II of this standard apply for lamps that have aged 100 hours. Lamp rms voltage may increase with operating hours; contact lamp manufacturer for details. 9.2 Warm-up time. Bare lamps operating in still air shall reach a s
37、tabilized voltage within the time limit and at the ambient temperature specified on the applicable lamp data sheet in Part II of this standard. For the purposes of this test, low pressure sodium lamps have reached a stabilized voltage when their voltage does not vary more than 2% in any one-minute p
38、eriod. Lamps shall meet this requirement when operated on the appropriate reference ballast specified in Part II, Section 4, and in the allowed operating position most adverse to warm-up. 10 Reference ballasts Reference ballasts shall meet the general requirements described in ANSI C82.5. 11 Ballast
39、 design General ballast requirements are described in ANSI C82.4. The following requirements shall be met over the full range of input voltage allowed for the ballast. 11.1 Open circuit voltage. The minimum ballast open circuit voltages shown on the individual lamp data sheets assure starting and op
40、erating reliability over lamp life. The percentage probability has not yet been determined. 11.2 Starting current. Starting current shall be measured 5 to 15 seconds after the lamp has been energized and shall be within the limits shown on the applicable lamp data sheet. Copyright 2006 by American N

Information for luminaire design 12.1 Lamp temperatures Luminaire design shall be such that the maximum lamp temperatures given in the physical characteristics section of the relevant lamp data sheet of Part II
42、are not exceeded. 12.2 Lamp operating position A luminaire shall maintain the lamp within its allowable operating position limits. 12.3 Maximum lamp outlines The information in clause 6 and the maximum lamp outlines in Part III provide guidance for the designers of luminaires. For mechanical accepta
43、nce of lamps complying with this standard, a free space should be provided in the luminaires based on these maximum outlines.
