PROBLEM TO BE SOLVED: To provide a light emission device that can drive plural light emission units independently of one another even when a single-sided board is used.SOLUTION: A light emission device comprises a substrate 1, a wiring portion formed on the substrate 1, and a plurality of light-emitting elements 2 disposed on the substrate 1 or the wiring portion. The plurality of light emitting elements 2 have a first light emission element group 10 which is covered with a first sealing member to constitute a first light emitting portion and a second light emitting element group 11 covered by a second sealing member which is formed so as to surround the first sealing member, thereby constituting a second light emitting portion. The wiring portion has a first wiring portion for driving the first light emitting element group 10 and a second wiring portion for driving the second light emitting element group 11. The second wiring portions 5a, 5c are formed to be spaced from each other across the first wiring portion 4a. A wire 12 for connecting the spaced second wiring portions 5a, 5c is connected across the first wiring portion 4a.SELECTED DRAWING: Figure 2 |
