Abstract

A LED lamp holder includes a lamp cover (1) and a heat-dissipating device (2) provided in the lamp cover (1). An accommodating inlet (110) is provided on the lamp cover (1). A LED unit (3) is provided below the lamp cover (1). A cover plate (13) covers the accommodating inlet (110). The heat-dissipating device (2) includes a heat-absorbing plate (20), a heat-dissipating plate (22) and a heat pipe (21) connected between the heat-absorbing plate (20) and the heat-dissipating plate (22). The heat-absorbing plate (20) is brought into contact with the LED unit (3), while the heat-dissipating plate (22) is brought into contact with the cover plate (13). The cover plate (13) is penetrated by a plurality of screw elements (14). Each of the screw elements (14) is screwed to the heat-absorbing plate (20). The length of each screw element (14) exactly makes the heat-absorbing plate (20) to abut and contact the LED unit (3).
