Title:
LED LIGHTING SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2020/116944
Kind Code:
A1
Abstract:
A LED lighting substrate according to an aspect according to the technical idea of the present invention comprises: a first body portion including a first electrode region and a second electrode region having electrically different polarities from each other; a second body portion extending from the first body portion; a branch portion that branches in plural and extends from the second body portion; a first element portion including a plurality of LED elements disposed in the branch portion and the second body portion; and a jumper portion, wherein the second body portion or the branch portion includes a first extension electrode region extending from the first electrode region and a second extension electrode region electrically connected to the second electrode region, the jumper portion electrically connects between the second electrode region and the second extension electrode region across the first electrode region, the first element portion includes a plurality of element sets that configure the plurality of LED elements connected to each other in series as one element set, and current flow directions of adjacent element sets are opposite to each other. Provided is an LED lighting substrate that simplifies circuit wiring through the first extension electrode region and the second extension electrode region while minimizing substrate waste through the branch portion.
