LED LAMP AND DRIVER CIRCUIT FOR LED LAMP

PROBLEM TO BE SOLVED: To provide a driver circuit for an LED lamp, and an LED lamp.SOLUTION: A driver circuit for an LED lamp comprises a thermistor with one end provided as a terminal for applying an external power source, a AC-DC conversion part connected to the other end of the thermistor for converting AC voltage applied to the other end into DC voltage, and a DC-DC conversion part for converting the DC voltage output from the AC-DC conversion part into DC voltage for driving an LED lamp. An LED lamp comprises an LED mount board on which at least one LED is mounted, a control circuit board on which necessary control circuits for operating the LED are mounted and whose one end includes both terminals for electrical connection with the LED, and a card edge connector which connects the LED mount board and the control circuit board and which is provided with a groove for inserting the both terminals formed on the control circuit board.
