US 2022/0149233 A1 · LIGHT-EMITTING MODULE

Abstract

A light-emitting module includes (i) a board provided with: a circuit pattern and a plurality of bottomed holes in each of a set of wiring pads continuous with the circuit pattern on a first surface; electrically conductive paste extending over two or more of the bottomed holes; and an insulating resin covering the electrically conductive paste at a side close to the first surface, and (ii) a plurality of light-emitting segments connected to a second surface of the board with an adhesive sheet interposed therebetween. The light-emitting segments each include a plurality of light-emitting devices that are aligned. The electrically conductive paste includes a portion disposed on a portion of a surface of the wiring pad extending over two or more of the bottomed holes.
