LED Light Source Module and Method for Producing the Same

A method for producing an LED light source module, comprising:

• providing a PCB board with at least one electrically conductive pathway, at least one semiconductor light-emitting device, electronic driving circuit components, and a metal housing with an upper surface and a grove capable of receiving the PCB board;
• producing at least one through hole on the PCB board;
• forming at least one heat sink capable of engaging with the through hole;
• disposing the heat sink in the through hole, and applying pressure on the heat sink by way of a mold so as to fixedly attach the heat sink to the PCB board;
• disposing the semiconductor light-emitting device on an upper surface of the heat sink;
• disposing the electronic driving circuit components on the PCB board;
• disposing the PCB board in the groove of the metal housing;
• and
• welding the heat sink with the upper surface of the metal housing.

A lighting source device comprising an LED light source module comprising:

• a metal housing with an upper and lower surface and a groove for receiving a PCB board;
• a PCB board with at least one electrically conductive pathway and at least one through hole, wherein the PCB board is disposed on the upper surface of and in the groove of the metal housing;
• electronic driving circuit components disposed on and operably connected with the at least one electrically conductive pathway of the PCB board;
• at least one heat sink having an upper surface and a lower surface and disposed in and connected with the through hole of the PCB board, wherein the lower surface of the at least one heat sink is welded with the upper surface of the metal housing;
• and
• at least one semiconductor light-emitting device disposed on the upper surface of the heat sink and operably connected to the at least one electrically conductive pathway.
