| 摘要 |
The present invention provides a lighting system which uses a stacked light emitting element provided with a plurality of light emitting units and causes little change in emission color even after a long time of usage. A lighting system is provided, including a first light emitting element including a plurality of light emitting units; a second light emitting element; a first control means which controls light emission of the first light emitting element; and a second control means which controls light emission of the second light emitting element, where the first light emitting element emits light of a first emission color that is an initial emission color and a second emission color that is an emission color after change over time, and the second light emitting element emits light of a complementary color of the second emission color. The above structure suppresses color shift due to change over time. |
