Light-emitting circuit and luminaire
First Claim
1. A light-emitting circuit comprising:
- a substrate;
a plurality of light-emitting portions arranged apart from each other on the substrate, each of a plurality of the light-emitting portions including a plurality of light-emitting elements configured to radiate light and a color mixing unit sealing the plurality of the light-emitting elements and configured to combine lights radiated from the plurality of the light-emitting elements; and
a luminous intensity distribution control member including a plurality of lenses provided corresponding to the plurality of the light-emitting portions, respectively, provided so that respective lights radiated from the plurality of the light-emitting portions enter the plurality of the lenses respectively, and configured to change luminous intensity distribution of the light-emitting portions,each of the color mixing units having a dome shape,the plurality of light-emitting elements of each of the light-emitting portions including a first light-emitting element configured to radiate light in a first wavelength range and a plurality of second light-emitting elements configured to radiate light in a second wavelength range that does not overlap with the first wavelength range,the first light-emitting element and the plurality of second light-emitting elements of each of the light-emitting portions being sealed with the same color mixing unit, andthe plurality of second light-emitting elements surrounding the first light-emitting element and arranged in a circular shape.

Abstract
According to one embodiment, a light-emitting circuit including a substrate, a plurality of light-emitting portions, and a luminous intensity distribution control member is provided. A plurality of the light-emitting portions are arranged apart from each other on the substrate. A plurality of the light-emitting portions each have a plurality of light-emitting elements and a color mixing unit. A plurality of the light-emitting elements radiate light. The color mixing unit combines the lights sealing a plurality of the light-emitting elements and radiated from a plurality of the light-emitting elements. The luminous intensity distribution control member includes a plurality of lenses provided corresponding to a plurality of the light-emitting portions, respectively, provided so that respective lights radiated from a plurality of the light-emitting portions enter a plurality of the lenses respectively, and configured to control the luminous intensity distribution of the light-emitting portions.
