Light emitting module, lighting device, and lighting apparatus

摘要

A light-emitting module includes: a first light-emitting element that emits light from an upper surface and side surfaces thereof; a second light-emitting element that mainly emits light from an upper surface thereof; a first sealer; and a second sealer. A first ratio, defined as a ratio of a heightwise distance from a top of the first sealer to the upper surface of the substrate with respect to a width of the first sealer at the upper surface of the substrate, is larger than a second ratio, defined as a ratio of a heightwise distance from a top of the second sealer to the upper surface of the second light-emitting element with respect to a width of the second sealer at a position corresponding to the upper surface of the second light-emitting element. A ratio of the first ratio to the second ratio is less than 1.85.

1. A light-emitting module, comprising:
a substrate; a first light-emitting element and a second light-emitting element that are each provided on an upper surface of the substrate and each emit light having a different peak wavelength; a first sealer that covers the first light-emitting element and includes a light-transmissive material; and a second sealer that covers the second light-emitting element wherein the first light-emitting element emits light from an upper surface and side surfaces thereof, the second light-emitting element mainly emits light from an upper surface thereof, a first ratio that is defined as, in a vertical cross section of the first sealer that passes through a center of the upper surface of the first light-emitting element, a ratio of a heightwise distance from a top of the first sealer to the upper surface of the substrate with respect to a width of the first sealer at the upper surface of the substrate, is larger than a second ratio that is defined as, in a vertical cross section of the second sealer that passes through a center of the upper surface of the second light-emitting element, a ratio of a heightwise distance from a top of the second sealer to the upper surface of the second light-emitting element with respect to a width of the second sealer at a position corresponding to the upper surface of the second light-emitting element, and a ratio of the first ratio to the second ratio is less than 1.85.
