  • LED projector light module
    Patent number: 7674015
    Abstract: 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.
