Energy saving electronic ballasts selection Ten empirical law:

Insulation layer selection: actual power in less than 20 watts of energy-saving lamps do not need insulation lights do not require insulation layer, needs more than 20 watts of energy-saving lamps in the shade on the installation of the insulation layer and outside air convection.

The core law: 7 watts of lights with EE10mm; lamp 11 watts EE13mm; lamp 15 watts EE16mm; lamp 20 watts EE19mm; lamp 40 watts EE25mm; 60 watts The following lamps EI28mm; lamps of 100 watts or less EI33mm.

In addition, the core gap law: 20 watts lamp with less than 0.6mm, 100-watt lamp with 0.8mm with 0.4mm, 40-watt lamp.

Pulse transformer selection of law (commonly known as the magnetic ring): 7 watts lamp ¢ 8mm 5K magnetic ring, magnet wire around 3:11:3. 7-20 watt lamp ¢ 10mm, 7K toroid magnet wire around 1:7:1. 20-30 watt lamp ¢ 10mm, 7K toroid wound into magnet wire 2:3:2. 30-40 watt lamp ¢ 10mm, 7K toroid magnet wire around 3:3:3. 40-50 watt lamp ¢ 10mm, 7K toroid magnet wire around 4:4:4. 50-100 watt lamp ¢ 10mm, 7K toroid magnet wire around by 2:3:2.

Filtering electrolytic capacitor selection rules is: less than 7 watts of lights 3.3uF ,11-15-watt lamps with 4.7uF ,15-20-watt lamps with 10uF 2.2uF ,7-11 watt lamps, 20 - 40-watt lamp with 22uF ,40-60-watt lamps with 33uF ,60-100 watt lamp 68uF.

Laws of lamp capacitance selection: first, lamp capacitor voltage value must be more than 1000 volts; Second, the choice of capacitance: less than 7 watts lamp with 152,7-15-watt lamps with 222,15 -20 watt lamp the 332,20-26 watt lamp 472,26-32 watt lamp 682,32-40 watt lights 882,40-50 watt lamp 103,50-60 watt lights 123,60-80 watt lamp with 153,80-100-watt lamp 183.

6. The triode optional rules: 7 watts of lights with 13001,7-15-watt lamp with 13002, 15-25 watts of lights with 13003,25-45 watt lamp with 13005,45-75 watt lamp with 13007 13009 ,75-100-watt lamp.

7. Fuse the selection rule: taking into account the current ballasts start below the 15-watt lamp with a safety ,15-26-watt lamp with 1.5 Ann ,26-45-watt lamps with 2 security 45-75 watt lamp 2.5A ,75-100 watt lamp with 3 safety.

The transistor base resistance law: less than 15 watts of lights with 1/4W 22 ohm, 15-25-watt lamp 1/2W 10 ohm, 25-45-watt lamp 1/2W 6.8 ohm ,45-75-watt lamp 1/2W 6.8 ohms ,75-100-watt lamp 1/2W, 4.7 ohm.

9. Transistor emitter resistor selection of law: less than 15 watts of lights with 1/4W 1 ohm; 15-25 watt lamp 1/4W 1 ohm; 25-45 watt lamp 1/2W 0.5 ohm ; 45-100 watt lamp 1W 0.5 ohm.

10. Law governing the use of electronic ballasts wire: 7 watts of lights with ¢ 0.10mm ,7-13 watt lamps with ¢ 0.17mm ,13-20-watt lamps with ¢ 0 ¢ 0.25mm ,20-40-watt lamp. 20mm × 3 shares, 40-100 watt lamps ¢ 0.20mm × 8 shares.
