This paper proposes the new concept LED Converter for CC/CV Implementation. In the market, many low cost CV LED Converters are used. CV circuit by connecting the CC circuit is used. The results were very short lifetime of the LED device. And LED converter of the failure rate was high. Determine the status of LED devices at the same time to control the voltage and current. The lifetime of the LED module has been improved.
