SUBSTRATE, LIGHT-EMITTING DEVICE, AND LIGHTING APPARATUS

摘要

A substrate on which LEDs are to be mounted to form an element row and which includes a first line and a second line disposed such that the element row is interposed therebetween. The first line includes a first main line portion extending mainly in the row direction of the element row, and a first connecting portion including a portion for connecting to the LEDs. The second line includes a second main line portion extending mainly in the row direction of the element row, and a second connecting portion including a portion for connecting to the LEDs. The gap between the first main line portion and the second main line portion is larger at LED mounting positions than at positions other than the LED mounting positions.
