LIGHT IRRADIATION SUBSTRATE

摘要

A light irradiation substrate (1) having: a flexible substrate (5); a first conductive material pattern (15) comprising wiring (2) and a dummy pattern (6) that are provided on the surface thereof; and LED chips (4) mounted upon the wiring (2). The surface of the first conductive material pattern (15) comprises a reflective material having a total flux reflection rate of at least 80% and has a surface coverage of at least 85% for the first conductive material pattern (15) at least within an area surrounded by the LED chips (4).
