Electric contact and connection type COB (chip on board)-LED light source module

The invention relates to an electric contact and connection type COB (chip on board)-LED light source module which comprises a reflection cup, a radiator, a COB-LED light source component, an electrical interface support and two single-core wires. Fastening grooves are arranged on the inner wall of a through hole of the electrical interface support, each fastening groove is formed by connection of an insertion opening with a sliding groove, fasteners corresponding to the fastening grooves are arranged at the outer edge of a small mouth of the reflection cup, a slot for insertion of a conducting strip is arranged on each of two side faces of the electrical interface support, and a telescopic conducting column is arranged in an accommodating cavity connected with the inner end of each slot. When the electric contact and connection type COB-LED light source module is assembled, the inner end of each conducting strip is connectedly sleeved on the corresponding conducting column, the exposed outer end of each conducting strip is mutually inserted with an insertion connector of the corresponding single-core wire, the bottom end of each conducting column penetrates through the electrical interface support to be pressed on a corresponding electric contact on a PCB (printed circuit board). Therefore, the electric contact and connection type COB-LED light source module has the advantages of compact structure, space saving and good radiating effect.
