Abstract:
A light-emitting device includes: a first light-emitting element and a second light-emitting element, each having a peak emission wavelength in a range of 430 nm to 480 nm; and a sealing member covering the first light-emitting element and the second light-emitting element, the sealing member containing a first fluorescent material. The first light-emitting element and the second light-emitting element are configured to be individually driven. The sealing member includes a protruding portion at an upper surface thereof. The first light-emitting element is disposed in a first region, which is located under the protruding portion. The second light-emitting element is disposed in a second region, which is located under the upper surface of the sealing member at a position different from the first region.
