LIGHT-EMITTING DEVICE AND LIGHTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device having high reliability by improving the strength of an electrode.SOLUTION: In a light-emitting device (1), an LED chip (32) is mounted on an insulating substrate (2), and a land electrode (4) and lead-out wiring (5) for supplying power to the LED chip are integrally formed on the insulating substrate. Only the land electrode is covered with a conductive material having higher hardness than Au and Ag.SELECTED DRAWING: Figure 1
