COUPLING APPARATUS OF LIGHTING LED MODULE

摘要

A coupling device is provided to improve working efficiency by coupling an E type base to a socket without the rotation of the LED lighting module. An E type base(20) is a metal cylinder. The E type base is coupled to a socket(10). An insulator(30) is inserted into the E type base. An A-1 contactor(40) and an A-2 contactor(50) are arranged inside the insulator. The A-1 contactor is protruded to the lower part of the E type base. The A-2 contactor is exposed to the upper part of the insulator. A B-2 contact piece is arranged on the insulator. A B-2 contact piece is electrically connected to the E type base. A fixing unit(70) is coupled in the upper side of the insulator. The A-3 contactor and the B-3 contactor are arranged inside the fixing unit. The fixing unit fixes the heat sink and a lighting cover.
