| 发明名称 | Light-emitting apparatus, lighting apparatus and lens | ||
| 摘要 | The light-emitting apparatus includes: a first light-emitting source which emits light of a first chromaticity from a first light-emitting surface; a second light-emitting source which has a second light-emitting surface provided adjacently to the first light-emitting surface and which emits light of a second chromaticity different from the first chromaticity, from the second light-emitting surface; and a lens member having a light-entering surface which is arranged facing the first light-emitting surface and the second light-emitting surface and on which depressions and projections that mix light entering from the first light-emitting source and the second light-emitting source are formed, and a light-exiting surface which radiates light from the first light-emitting source and the second light-emitting source that has entered from the light-entering surface. | ||

| 主权项 | 1. A light-emitting apparatus, comprising: a first light-emitting source which emits light of a first chromaticity from a first light-emitting surface; a second light-emitting source which has a second light-emitting surface provided adjacently to the first light-emitting surface and which emits light of a second chromaticity different from the first chromaticity, from the second light-emitting surface; and a lens member having a light-entering surface which is arranged facing the first light-emitting surface and the second light-emitting surface and on which depressions and projections that mix light entering from the first light-emitting source and the second light-emitting source are formed, and a light-exiting surface which radiates light from the first light-emitting source and the second light-emitting source that has entered from the light-entering surface; wherein a distance from the light mixing member to the first light-emitting source and a distance from the light mixing member to the second light-emitting source are each no less than 0.5 times and no more than 2 times a distance between the first light-emitting source and the second light-emitting source. | ||
