Patent ID: 8803186

Claim:
A lighting module, comprising: a carrier board ( 4 ); an insulating substrate ( 11 ) disposed on the carrier board, having a bottom surface ( 11 A), a mounting surface ( 11 F) opposite to the bottom surface, and two opposing first lateral surfaces ( 11 B/C) connected between the bottom surface and the mounting surface, wherein one of the two first lateral surfaces is defined as a substrate contact surface for establishing contact with the carrier board; a conducting portion ( 12 ) disposed on a central region of the bottom surface ( 11 A) of the substrate ( 11 ) traversing across the lateral surfaces ( 11 B/C) thereof, wherein the conducting portion ( 12 ) comprises at least one expansion region ( 122 ) adjacent to the substrate contact surface and has a first cutting segment ( 121 ) formed at a contact border defined between the substrate contact surface and the bottom surface, wherein the width of the first cutting segment is shorter than any segment taken on the expansion region parallel thereto; at least one light emitting component ( 2 ) disposed on the mounting surface ( 11 F); and a packaging member ( 3 ) covering the light emitting component.
