Document Type and Number:
Japanese Patent JP2018092810
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light emitting device facilitating power supply to other light emitting devices.SOLUTION: A light emitting device 10 includes: a substrate 11 having a structure where a first wiring layer 16a and a second wiring layer 16b are laminated across an insulation layer 17; a pair of power source wirings 13 which are a pair of power source wirings 13 running parallel to a first direction and transmit AC power to a second terminal structure from a first terminal structure; a plurality of circuit elements 15 composing a power supply circuit; and an LED element 14 emitting light using electric power output by the power supply circuit. A first power supply wiring 13a of the pair of power supply wirings 13 is formed as a part of the first wiring layer 16a, and a second power supply wiring 13b of the pair of power supply wirings 13 is formed as a part of the second wiring layer 16b.SELECTED DRAWING: Figure 4
