LED LIGHTING LAMP WITH ENHANCED HEAT DISSIPATION FUNCTION

摘要

Disclosed is an LED lighting lamp with an enhanced heat dissipation function. The LED lighting lamp is configured to be fitted into and connected to a socket, enables high temperature heat generated when LEDs are turned on to be rapidly dissipated to the outside through heat dissipation fins formed in a main body so as to have a further improved heat dissipation function, and allows simple assembly thereof so as to significantly improve productivity and repair workability. The lighting lamp of the present invention includes a main body which has a fitting hole formed inwardly through a center portion of an upper surface of the main body, a plurality of heat dissipating fins formed along an outer peripheral surface of the fitting hole, and a mounting surface formed on a lower portion of the main body, the mounting surface having a single annular heat dissipating groove or a plurality of annular heat dissipating grooves, an LED module which is installed to be in close contact with the mounting surface formed on the lower portion of the main body and has a plurality of LEDs installed on a bottom surface of the LED module, a cylindrical fastening boss which is fastened by means of a screw to the LED module, which is in close contact with the mounting surface of the main body, while being fitted and coupled through the fitting hole from an upper side of the main body, a connection portion which is fitted into and electrically connected to a socket provided on a ceiling, a wall surface, or the like while being fitted and fixed to an outside of an upper portion of the fastening boss, a lens holder which is fitted and coupled to the bottom surface of the LED module so as to be spaced apart therefrom by a predetermined distance and has lenses mounted at positions corresponding to the respective LEDs constituting the LED module so as to diffuse illumination light emitted from the LEDs and irradiate the illumination light, and a ring-shaped fixing cap which is coupled to a lower end of the main body and is fastened to the lower end by means of a screw while enclosing the LED module and the lens holder.
