3 Definitions
For the purpose of this part of lEC 61000，the following definitions apply,as well as thedefinitions of IEC 60050(161).
3.1
portable tool
an electrical tool which is hand-held during normal operation and used for a short time (a fewminutes) only
3.2
lamp
a source for producing light
3.3
self-ballasted lamp
a unit which cannot be dismantled without being permanently damaged,provided with a lampcap and incorporating a light source and any additional element necessary for starting andstable operation of the light source
3.4
luminaire
an apparatus (other than a lamp) which distributes,filters or transforms the light transmittedfrom one or more lamps and which includes all the parts necessary for supporting, fixing andprotecting the lamps, and,where necessary，circuit auxiliaries,together with the means forconnecting them to the supply

3.5
semi-luminaire
a unit similar to a self-ballasted lamp but designed to utillize a replaceable light source andlorstarting device
3.6
ballast
a device connected between the supply and one or more discharge lamps which serves mainlyto limit the current of the lamp(s) to the required value. It may include means for transformingthe supply voltage and/or frequency，correcting the power factor and,either alone or incombination with a starting device, provide the necessary conditions for starting the lamp(s)
3.7
step-down converter for lighting equipment
a unit inserted between the supply and one or more tungsten halogen or other filament lampswhich serves to supply the lamp(s) with its (their) rated voltage, generally at high frequency.The unit may consist of one or more separate components. It may include means for dimming,correcting the power factor and suppressing radio interference
3.8
lighting unit
lighting equipment consisting of one self-ballasted lamp or the combination of one controldevice (ballast, semi-luminaire,transformer or the like) operating one or more lamps
3.9
reference lamp
a lamp selected for testing ballasts which，when associated with a reference ballast。haselectrical characteristics that are close to the objective values given in the relevant lampspecification
3.10
reference ballast
a special inductive-type ballast designed for the purpose of providing comparison standards foruse in testing ballasts and for the selection of reference lamps. lt is essentially characterizedby a stable voltage-to-current ratio，which is relatively uninfluenced by variations in current,temperature, and the magnetic surroundings
3.11
input current
current directly supplied to an equipment or a part of equipment by the a.c. distribution system
3.12
circuit power factor
the circuit power factor is the ratio of the measured active input power to the product of thesupply voltage (r.m.s.) and the supply current (r.m.s.)
3.13
active power
the mean value,taken over one period, of the instantaneous power[EV 131-03-18]
NOTE The active input power is the active power measured at the input supply terminals of the equipment undertest.
3.19
lighting equipment
equipment with a primary function of generating and/or regulating and/or distributing optical
radiation by means of incandescent lamps, discharge lamps or LED’s
Included are:
一，lamps and luminaires;
一the lighting part of multi-function equipment where one of the primary functions of this is
illumination; independent ballasts for discharge lamps and independent incandescent lamp
transformers; ultraviolet (UV) and infrared (IR) radiation equipment; illuminated advertising signs; dimmers for lamps other than incandescent.
