| 发明名称 | Light-emitting device | ||
| 摘要 | A light-emitting device includes a support body having a quadrangle planar shape, a wiring pattern on the support body, a light-emitting element on the wiring pattern, a recognition target portion on a corner portion of the support body, the recognition target portion including a conductive material, an insulation layer reflecting light emitted from the light-emitting element and covering a periphery of the recognition target portion, and a light-transmissive member including a lens portion covering the light-emitting element and a flange portion on a periphery of the lens portion and covering a portion of the recognition target portion that is covered with the insulation layer. The portion of the recognition target portion covered by the flange portion is arranged in a non-point symmetry around a center of the support body, and a difference in reflectivity between the support body and the insulation layer is larger than between the support body and the recognition target portion. | ||

| 主权项 | 1. A light-emitting device, comprising: a support body having a quadrangle planar shape; a wiring pattern on the support body; a light-emitting element on the wiring pattern; a recognition target portion on a corner portion of a plan view of the support body, the recognition target portion comprising a conductive material; an insulation layer reflecting light emitted from the light-emitting element and covering at least a periphery of the recognition target portion; and a light transmissive member that includes a lens portion covering the light-emitting element, and a flange portion arranged on a periphery of the lens portion and covering at least a part of the recognition target portion that is covered with the insulation layer, wherein the recognition target portion is arranged so that the portion of the recognition target portion covered by the flange portion is arranged in a non-point symmetry around a center of the support body, wherein a difference in reflectivity between the support body and the insulation layer is larger than a difference in reflectivity between the support body and the recognition target portion, and wherein a length of the recognition target portion from a periphery of the lens portion an outermost edge of the recognition target portion is 0.3 mm or more. | ||
