Patent ID: 11879607
Assignee: NICHIA CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC F  H | IPC F

Claim 0:
1. A light-emitting device comprising:
a light-emitting element including
a support substrate having a first surface and a second surface opposite to the first surface, and
a first light-emitting portion and a second light-emitting portion disposed adjacent to each other on the second surface of the support substrate, the first light-emitting portion and the second light-emitting portion each including a semiconductor layered body including a first semiconductor layer, a light-emitting layer, and a second semiconductor layer in this order;

a wavelength conversion member disposed on the first surface of the support substrate and containing a phosphor configured to perform wavelength conversion of first light emitted from the first light-emitting portion and second light emitted from the second light-emitting portion into third light; and
a light adjustment member disposed on a surface of the wavelength conversion member opposite to a surface on a support substrate side or disposed inside the wavelength conversion member, the light adjustment member overlapping one of the first light-emitting portion and the second light-emitting portion in a plan view, wherein
in the light-emitting element, an emission intensity of the first light at a light emission peak wavelength of the second light is lower than an emission intensity of the second light at the light emission peak wavelength of the second light, during light emission of the light-emitting device.
