Lighting Product Line
Power Conversion
Ballast Standard
IEC (International Electrotechnical commission)
 Starting Mode
 IEC929 : 1990 / 1st edition
AC supplied electronic ballasts for tubular fluorescent lamps-Performance requirements
 7. Preheat starting mode  Need a IC for frequency control
7.1. minimum preheat time : 0.4S
maximum effective heating current : not exceed lamp datasheet limit
maximum open-circuit voltage : not exceed lamp datasheet limit
 Protection Mode
 IEC61347-2-3 : 2000
Particular requirements for ac supplied electronic ballasts for fluorescent lamps
 16. Abnormal conditions  FAN7710/1 cover without external components
a) the lamps or one of the lamps is not inserted.
b) the lamp doesn't start because one of the cathodes is broken
c) the lamp doesn’t start although the cathode circuits are intact (de-activated lamp)
d) the lamp operates, but one of the cathodes is de-activated or broken
e) short circuit of the starter switch, if any
 17. Behavior of the ballast at end of life  FAN7713 will cover
 Mandatory claim for T4/T5 Lamp
a) asymmetric pulse test, b) asymmetric power dissipation test, c) open filament test
 NA, EU, JP, KR Government follow IEC ( http://www.iec.ch/ ) !!!!!
 EN60929/61347, BSEN60929/62347, KSCIE60929/61347
