To provide a light source unit or the like which efficiently irradiates a road surface with light.SOLUTION: A light source unit 100 includes a housing 110, a light source 120 which is housed in the housing 110 and irradiates downward with light, and a lens 130 which covers a lower side of the light source 120 and is arranged on the housing 110. The lens 130 has a protrusion part 132 which is arranged on an inner surface positioned on a vehicle 200 side than an optical axis 310 of illumination light 300, which the light source 120 irradiates when the light source unit 100 is arranged on a vehicle 200, and protrudes to a light source 120 side. The protrusion part 132 includes a first surface where a normal direction faces the vehicle 200 side and a second surface where a normal direction faces the light source 120 side. An angle formed by the optical axis 310 and the first surface is larger than an angle formed by the optical axis 310 and the second surface.SELECTED DRAWING: Figure 4
【課題】路面に効率的に光を照射する光源ユニット等を提供する。【解決手段】光源ユニット100は、筐体110と、筐体110に収容され、下方に向けて光を照射する光源120と、光源120の下方を覆い、筐体110に配置されるレンズ130と、を備える。レンズ130は、光源ユニット100が車両200に配置された場合に、光源120が照射した照明光300の光軸310より車両200側に位置する内面に、光源120側に突出する凸部132を有する。凸部132は、法線方向が車両200側に向く第1面と、法線方向が光源120側に向く第2面とを含む。光軸310と第1面とのなす角は、光軸310と第2面とのなす角より大きい。【選択図】図4
