A LED projector light module comprising a main body, a LED unit, a heat-radiating unit, a voltage conversion unit and a base is disclosed. The main body is made of metallic material with good thermal conductivity (e.g. copper) and contains a space for accommodating the LED unit. The LED unit and the voltage conversion unit are electrically connected. The voltage conversion unit is configured inside the base. The base is connectable to the main body. The bottom surface of base is disposed with an electrically conductive pin that matches the projector socket. The electrically conductive pin is electrically connected to the voltage conversion unit at one end. The invention is characterized in which the heat-radiating unit is arranged at the outer rim of main body and the heat generated by the LED unit can be effectively transferred to the heat-radiating unit through the main body and then rapidly dissipate, which enhances the efficiency of heat dissipation, thereby allowing the use of higher wattage LED to enhance luminance.
