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

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of LED lighting using a COB-LED chip-packaged light source module, in particular to a COB-LED light source module of an electric contact type. Background technique [0002] In the light source module of LED lighting, the use of COB-LED chip packaging—that is, the LED chip packaging on the PCB is gradually warming up with the characteristics of low cost and good heat dissipation, and gradually enters the field of vision of LED enterprises and consumers. [0003] At present, most of the existing light source modules packaged with COB-LED chips adopt the GE standard structure of the United States. The structure is to screw the COB-LED light source assembly above the middle through hole of the electrical interface bracket through screws. The assembly method is not conducive to the heat dissipation of the COB-LED light source component, and the export of the core wire of this structure requires more space, which ...

Problems solved by technology

[0003] At present, most of the existing light source modules packaged with COB-LED chips adopt the GE standard structure of the United States. The structure is to screw the COB-LED light source assembly above the middle through hole of the electrical interface bracket through screws. The assembly method is not conducive to the heat dissipation of the COB-LED light source component, and the lead-out of the core wire of this structure requires more space, which makes the product structure not compact enough. In addition, the structure requires screws and The structure of the screw hole has many parts, and it is troublesome to process and disassemble.
