Disclosed is an apparatus for testing an LED lamp which includes: a secured seat on which the LED lamp is seated; an up and down shifter which, when the LED lamp is seated on the secured seat, shifts from an initial position spaced upward from the LED lamp to a measurement position in which the up and down shifter contacts with a socket of the LED lamp, and which supplies electric power to the LED lamp when the up and down shifter is placed in the measurement position, and a sensor sensing that the up and down shifter is placed in the measurement position; and a quality determining means determining a quality of the LED lamp based on light emitted from the LED lamp, and comprising an illuminometer or a luminance meter.

Testing apparatus and method for testing light emitting diode lamp

Disclosed is a method for operating a test apparatus for an LED lamp. The method includes: forming a self-holding circuit by switching on a first switching means such that an up and down shifter provided in the test apparatus for the LED lamp moves down; moving down and stopping the up and down shifter from a determined initial position to a measurement position; measuring the quality of the LED lamp equipped with the test apparatus for the LED lamp; releasing the self-holding circuit by switching on the second switching means such that the up and down shifter moves up; and moving up and down shifter from the measurement position to the determined initial position.
