LIGHT-EMITTING DEVICE |
摘要 |
A light-emitting device includes a substrate; a lens array having a plurality of lens sections in a matrix pattern; and a plurality of semiconductor laser elements disposed on the substrate. Each of the semiconductor laser elements emits a respective laser beam, each laser beam having a beam shape with a greater width in a column direction than in a row direction on a light incident surface of each respective lens section. The lens sections have an inter-vertex distance in the row direction that is smaller than both (i) a maximum outer diameter of each of the lens sections, and (ii) an inter-vertex distance in the column direction. A curvature of the lens sections in the row direction is the same as a curvature of the lens sections in the column direction. |

1. A light-emitting device comprising:
a substrate; a lens array having a plurality of lens sections in a matrix pattern; and a plurality of semiconductor laser elements disposed on the substrate, wherein each of the semiconductor laser elements emits a respective laser beam, each laser beam having a beam shape with a greater width in a column direction than in a row direction on a light incident surface of each respective lens section, wherein the lens sections have an inter-vertex distance in the row direction that is smaller than both (i) a maximum outer diameter of each of the lens sections, and (ii) an inter-vertex distance in the column direction, and wherein a curvature of the lens sections in the row direction is the same as a curvature of the lens sections in the column direction. |
