light-emitting device

Abstract

A light-emitting device (1) comprises: a light source (10) that emits light; a lens (11) having a bottom-mounted tube shape, onto which the light emitted by the light source (10) is incident and which projects the incident light; and a structural component (12) to which the light source is attached. The lens (11) comprises: a light projection section (110), which is a bottom section of the bottom-mounted tube shape and projects the light; a wall section (114), which is a tube section of the bottom-mounted tube shape and rises from an outer circumference of the light projection section (110); and a position fixing component (116) that fixes the structural component (12) to the lens (11). The position fixing component (116) is arranged at a position that overlaps with the light projection section (110) in a plan view of the light projection section (110).
