OVERVIEW
2-in-1 Transformer
Innovation transformer technology for CCFL(Cold Cathode Fluorescent Lamp) inverter.
Two symmetric secondary output for two group lamps in one transformer.
A very creative transformer solution for CCFL inverter design neck of bottle problem when device need more than one lamp.
Different models available.
EFD16.4¡¡EFD16.6¡¡UU18.5¡¡EFD18¡¡EEL22¡¡are available now.
EFD41(using for FFL and EEFL)¡¡EEL14, EEL15 are in developing.
FEATURES
Winding construction
One or two primary in the central of bobbin.
Two secondary in the two sides of bobbin symmetrically
Multi-slot for secondary Hi-voltage distribution and leakage inductance adjustment
Additional insulation spacer to enforce safety
One set core for 2 transformers.
Run very well with MPS and BITEK 's controller IC
Patent was approved at Korea, TaiWan and China.
BENEFITS
Individual two outputs are easy to control brightness by individual current.
Two outputs in series can provide high voltage for lamps in series also
Dimming symmetrically as two symmetrical outputs
Small size, narrow shape
Cost reduction
EXISTING MUTIL-LAMPS INVERTER
THE NECK OF BOTTLE OF EXISTING
In parallel
Individual lamp with different current
Hard to control appropriate level current (2~7mA)
In Series
Very high starting voltage requirement in one transformer
Secondary of transformer need many slots for winding. It is construction and winding limit.
It is not symmetrical in two transformers and cost higher
