It becomes.

次に、本発明の実施形態を説明するが、それはあくまで本発明に基づいて採択された例示的な実施形態であり、本発明をその実施形態に特有な事項に基づいて限定解釈してはならず、本発明の技術的範囲は、特許請求の範囲の請求項に示した事項さらにはその事項と実質的に等価である事項に基づいて定めなければならない。 Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention should not be limitedly interpreted based on matters specific to the embodiment. The technical scope of the present invention should be determined based on the matters shown in the claims of the claims and matters substantially equivalent to the matters.

図示の実施形態は、下記要件(A)〜(C)を備えた照明装置である。
(A) 複数の曲線状の導光棒１を光源部ケース２で連結して導光リング状とする。
(B) 前記光源部ケース２には前記導光棒１の端部に光を導入する光源３を収めて前記導光棒１を発光可能とする。
(C) 前記光源部ケース２を照明器具本体４からの支持部材５で支持するとともに、前記光源部ケース２内の光源３に給電可能としたリード線６を前記支持部材５に沿わせて配線する。 The illustrated embodiment is a lighting device having the following requirements (A) to (C).
(A) A plurality of curved light guide rods 1 are connected by a light source section case 2 to form a light guide ring shape.
(B) The light source section case 2 houses a light source 3 for introducing light into the end of the light guide bar 1 so that the light guide bar 1 can emit light.
(C) The light source unit case 2 is supported by the support member 5 from the luminaire main body 4, and the lead wire 6 that can supply power to the light source 3 in the light source unit case 2 is wired along the support member 5. To do.

The light passing through the inside is irregularly reflected, whereby exposure (light emission) is performed from the surface (side surface) of the light guide rod 1. The light source case 2 is formed of a light-shielding resin or the like, and is connected with the light guide rod 1 sandwiched between the inner and outer sets by fixing them together. The light source 3 is preferably a light emitting diode element, for example, and is mounted on a substrate 8 housed in the light source unit case 2. The back surface of the light source unit case 2 is supported by a support member 5, and the base portion of the support member 5 is fixed to the upper surface of the luminaire main body 4. A lead wire 6 to which an appropriate DC voltage is applied is drawn from the inside of the luminaire body 4 to the upper surface at an appropriate location, introduced into the light source case 2 through the inside or the lower surface of the support member 5, and connected to the substrate 8. Has been.
