A dental lighting lamp includes a body, a reflector, a lamp body, a distance sensor and a control circuit, wherein the reflector and the lamp body are arranged on the body, the lamp body is electrically connected to the control circuit and emits light towards the reflector, and the light is reflected by the reflector and is separated from the body.The distance sensor is electrically connected to the control circuit to sense the distance of the object covered in front of it, and is converted into a distance signal to be transmitted to the control circuit, and the control circuit further converts the distance signal into a control signal, so as to control the intensity of the light emitted by the lamp body.一種牙科用照明燈，其包括有一本體、一反光罩、一燈體、一距離感測器及一控制電路，其中反光罩及燈體設於本體上，燈體電性連接於控制電路並朝反光罩發射光線，且光線受反光罩反射而離開本體。距離感測器電性連接於控制電路，用以感測遮蔽在其前方之物體的距離，並轉換為距離訊號傳送至控制電路，且控制電路進一步將距離訊號轉換為控制訊號，藉以控制燈體發光之強弱度。
