LED MOUNTING SUBSTRATE, AND ILLUMINATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an LED mounting substrate having an LED element mounted on a printed circuit board, in which emission amount loss of an LED is suppressed at the minimum and the reliability of mounting by improving connection strength of a soldering portion between a lead terminal of the LED element and a terminal pad of the printed circuit board.

SOLUTION: In the LED mounting substrate 1a in which the LED element 20 is mounted on the printed circuit board 10a applied with a white solder resist 12, pads 13 connected to terminals 23 of the LED element are formed on the printed circuit board and a white resin 30 containing a white pigment is applied on the surface of the printed circuit board so as to cover the wiring region between terminal and the pads.
