Abstract

A light emitting module is provided in which color unevenness of illumination light is difficult to occur. An optical member formed from a translucent material having a refractive index higher than air is interposed between a first light emitting part and a second light emitting part. A side surface of the optical member has a region facing a first sealing member, and the region is at least partially in contact with a surface of the first sealing member. The side surface of the optical member has a region facing a second sealing member, and the region is at least partially in contact with a surface of the second sealing member. In plan view, an upper surface of the optical member does not substantially overlap either of an upper surface of a first light emitting element or an upper surface of a second light emitting element.

Dependent claims

A light emitting module comprising a first light emitting part and a second light emitting part that are provided on an upper surface of a substrate with an interval therebetween and differ from each other in terms of luminescent color, the first light emitting part including a first light emitting element and a first sealing member sealing the first light emitting element, the second light emitting part including a second light emitting element and a second sealing member sealing the second light emitting element, wherein

an optical member is interposed between the first light emitting part and the second light emitting part, and is formed from a translucent material having a refractive index higher than air,
a side surface of the optical member includes a first region facing the first sealing member and a second region facing the second sealing member, the first region is at least partially in contact with a surface of the first sealing member, and the second region is at least partially in contact with a surface of the second sealing member, and
in plan view, an upper surface of the optical member does not substantially overlap either an upper surface of the first light emitting element or an upper surface of the second light emitting element.
