' AC power driven LEDs have been commercialized by other manufacturers and =
=0A=
these types of devices can be easily downsized due to their simplified =0A=
drive circuits. However, when compared with DC power driven LEDs, =0A=

Citizen Electronics=92 new products can be driven directly by an AC power =

supply by adopting an innovative technique called SCD (Selective Current =
=0A=
Diversion technique) in the LED drive circuits. Accordingly, the modules do=
 =0A=
not need a DC power circuit, and downsizing and slimming of the products =
=0A=
has been accomplished successfully. In addition, their zero lighting time =
=0A=
has been reduced compared with that of existing AC driven LEDs and a huge =
=0A=
increase in efficiency has also been achieved.=0A=
