An operating lamp apparatus includes a central pillar, a ring-shaped light guide structure, a reflection cover structure, a reflection member, and a light source device. The ring-shaped light guide structure jackets the central pillar and has a light-entrance end and a light-exit end. The reflection cover structure is connected to a top end to surround the central pillar. The reflection member jackets the central pillar corresponding to the light-exit end and has a reflection surface. The light source device jackets the central pillar corresponding to the light-entrance end. Light emitted by the light source device enters the ring-shaped light guide structure via the light-entrance end and is emitted out of the light-exit end to the reflection surface. Subsequently, the light is reflected to the reflection cover structure by the reflection surface, so as to generate a light spot via light concentration of the reflection cover structure.一種手術燈設備包含中央柱體、環形導光結構、反射罩結構、反射構件及光源裝置。環形導光結構套設於中央柱體上且具有入光端部及出光端部。反射罩結構連接於中央柱體之頂端以環設於中央柱體之周圍。反射構件套設於中央柱體對應出光端部之位置上且具有反射面。光源裝置套設於中央柱體對應入光端部之位置上,光源裝置所發射之光線經由入光端部進入環形導光結構且從出光端部射出至反射面,並接著經由反射面反射至反射罩結構,使得光線經由反射罩結構之聚光產生投射光斑。
