SMART CONVERTER THAT HAVE LED MODULE REALIZATION FUNCTION

摘要

PURPOSE: A smart converter with an LED module recognition function is provided to constantly maintain light output by controlling a power supply condition in an A/D converter. CONSTITUTION: A module recognition unit(30) is connected in parallel with a recognition device when an LED module is replaced. A module recognition unit output a terminal voltage divided from a parallel connection with the recognition device. A power control unit(40) applies constant power to the recognition when the replaced LED module is connected to the A/D converter and applies the constant power to the LED module according to the terminal voltage. The terminal voltage is outputted from the module recognition unit and is applied to an input port.
