ANSI C82.13-2002 Copyright 2002 by American National Standard Lighting GroupNEMA 5 multiple shape (M): The shape designation for a single-based lamp using a combination of tubes (multiple) which is not covered by any other shape designation. normative reference: Publication conta

27、alue used to designate or identify a component, device or equipment. (see also IEV-151-0401) parallel cathode heating: A method of supplying cathode heating voltage from one ballast winding to two cathodes that are electrically connected in parallel to that winding. programmed start system: Those sy
28、stems in which the sequence for starting of hot-cathode electric discharge lamps is as follows: (1) the lamp cathodes are initially preheated to a temperature sufficient for adequate electron emission and without establishing local ionization across the cathodes; (2) this heating is accomplished by
29、supplying the required energy from a voltage or current source in the ballast itself, while during the preheating period the voltage across the lamp is kept below a level to initiate a glow discharge; (3) after the preheating period the voltage across the lamp is increased to a sufficient level to i

31、nterference suppression capacitor: A capacitor, usually located in the base of certain lamps or in an external starter, which is connected in parallel to the lamp in order to suppress radio interference. Such a capacitor, if located in a lamp, will be specified on the lamp data sheet. rapid-start ty
32、pe systems: Those systems in which hot-cathode electric discharge lamps are operated under the following conditions: (1) the lamps are started with the cathodes heated to a temperature sufficient for adequate electron emission and without establishing local ionization across the cathodes; (2) such h
33、eating is accomplished either by means of low-voltage heater windings in the ballast itself, by separate low-voltage transformers, or by other means of heating the cathodes/ (3) sufficient voltage is applied across the lamp and between the lamp and the starting aid (usually the fixture itself) to in

ANSI C82.13-2002 6 Copyright 2002 by American National Standard Lighting GroupNEMA Note - Two types of rapid-start systems hav
35、e evolved: (1) those for lamps with nominal 3.6 volt cathodes (low resistance) and (2) those for lamps with nominal 8.0 volt cathodes (high resistance). In some cases the same lamp can be suitable for operation in either rapid-start or switch start (preheat-start) system. rated lamp life: The length
36、 of time declared by the manufacturer during which 50% of any large number of lamps reach the end of their individual lives. rated value: A quantity value for specified operating conditions of a component, device or equipment. The value and conditions are specified in the relevant standard or assign
37、ed by the manufacturer or responsible vendor. (see also IEV-151-04-03) rating: The set of rated values and operating conditions. (see also IEV-151-04-04) reference current: That value of current at which the impedance of a reference ballast is specified and measured. The reference current for each s
38、ize of reference ballast is normally the same as the rated current of the lamp type which the ballast is intended to operate. Since the reference ballast is a standard that is representative of the impedance of lamp power sources installed, it is not necessary to change this current value unless maj
39、or changes in lamp standards require modification of the ballast impedance. The reference current for each reference ballast is specified in the applicable American National Standard for the Dimensional Electrical Characteristics of Fluorescent Lamps , ANSI C78.81, and C78.901. reference lamps: Seas
40、oned lamps which under stable operating conditions and in conjunction with the specified reference ballast operate at values of lamp voltage, lamp wattage (for rapid-start lamps arc wattage is to be used and not total wattage), and lamp current, each within 2-1/2% of the values given in the appropri
41、ate lamp standard (see American National Standard Dimensional and Electrical Characteristics of Fluorescent Lamps, ANSI C78.81, and C78.901). Reference lamps of the rapid-start type are operated in circuits in which their cathodes are continuously heated by appropriate low-voltage power sources. run
42、-up time: The time needed after switching on the supply for the lamp to reach 80% of its stabilized luminous flux. self-ballasted compact fluorescent lamp: A compact fluorescent lamp unit that incorporates, permanently enclosed, all elements that are necessary for the starting and stable operation o
43、f the lamp, and which does not include any replaceable or interchangeable parts. The unit is intended as an alternative to an incandescent lamp in an existing Edison screw lampholder. For test purposes, self-ballasted lamp units shall be regarded as conventional lamps. self-supporting, single-based
44、compact fluorescent lamp: A fluorescent lamp of small, compact shape with a single base which performs the entire mechanical support function. ANSI C82.13-2002 Copyright 2002 by American National Standard Lighting GroupNEMA 7 square shape (S): The shape of a single-based lamp in which the tube is fo
45、rmed into a nominally square shape. starting aid: A grounded, conductive plane located parallel to a lamp. It can be a conventional part of the luminaire. The voltage difference between a lamps cathode and the plane aids in initiation of the discharge. starting time: The time needed after switching
46、on for the lamp to start fully and remain lighted at the supply voltage and temperature defined in the requirements section. switch-start (preheat) systems: Systems in which hot-cathode electric discharge lamps are started with the cathodes preheated through the use of a starting switch, either manu
47、al or automatic in its operation;. The starting switch, when closed, connects the two cathodes, in series, in the ballast circuit so that current flows to heat the cathodes to emission temperature. When the switch is opened, a voltage surge is produced which initiates the discharge. Only the arc cur
48、rent flows through the cathodes after the lamp is in operation. total harmonic distortion: This term has caused some confusion and is not always defined in the same way Read any standard carefully to determine which definition is being used. Typically in the U.S. it refers to the ratio of the rms va
49、lues of the harmonic content to that of the fundamental current, expressed as a percentage. It may also be called Harmonic Factor 21242322.)(IIIIfundTHD+= Another definition of total harmonic distortion is the ratio of the harmonic content to the rms value of the periodic current (all of the harmonic components including the fundamental) expressed as a percentage. This definition is used in CSA and IEC standards. THD rmsIIIIrms().=+223242triple shape (TR): The shape of a single based lamp in which the bulb of the finished lamp consists of three twin tub
