Description
前記した課題を解決するために、本発明に係る照明装置は、円筒状に形成された面発光部を有し、前記面発光部の発光により光照射がなされる照明装置であって、前記面発光部の一端が内周縁を構成し、前記面発光部の他端が外周縁を構成すると共に、前記内周縁から外周縁に向かって、同心円状に広がる勾配を持たせたことをことに特徴を有する。
この場合、前記面発光部の上端部が内周縁を構成し、前記面発光部の下端部が外周縁を構成することが望ましい。また、前記面発光部は、短冊状に形成された複数の面発光体により構成され、前記各面発光体の長手方向の一端部が前記内周縁を構成し、前記各面発光体の長手方向の他端部が前記外周縁を構成するようにして前記各面発光体が環状に配列されることが望ましい。また、前記円筒状の面発光部は、その発光面が下方に臨む状態で配置されていることが望ましい。
また、上端が前記内周縁に沿って形成され、下端が前記外周縁に沿って形成されると共に、前記内周縁から前記外周縁に向かって周面が同心円状に広がる勾配を有する筒状体を備え、前記筒状体は透光性を有し、前記面発光部は前記筒状体の周面上に設けられていることが望ましい。
尚、前記筒状体は、弾性素材により形成された複数の円弧状の平板部材が連結され、湾曲されることにより構成されていてもよい。その場合、前記平板部材を透明基板として、該平板部材の一面上に前記面発光部の透明電極を形成することもできる。
In order to solve the above-described problems, an illumination device according to the present invention is a lighting device that has a surface light emitting portion formed in a cylindrical shape and is irradiated with light by light emission from the surface light emitting portion. One end of the light emitting portion constitutes an inner peripheral edge, the other end of the surface light emitting portion constitutes an outer peripheral edge, and has a gradient spreading concentrically from the inner peripheral edge toward the outer peripheral edge. Have
In this case, it is desirable that the upper end portion of the surface light emitting portion constitutes an inner peripheral edge and the lower end portion of the surface light emitting portion constitutes an outer peripheral edge. Further, the surface light emitting portion is constituted by a plurality of surface light emitters formed in a strip shape, and one end portion in the longitudinal direction of each surface light emitter constitutes the inner peripheral edge, and the longitudinal direction of each surface light emitter. It is preferable that the surface light emitters are arranged in an annular shape so that the other end of the surface constitutes the outer peripheral edge. Further, it is desirable that the cylindrical surface light emitting portion is disposed in a state where the light emitting surface faces downward.
A cylindrical body having an upper end formed along the inner peripheral edge, a lower end formed along the outer peripheral edge, and a gradient in which a peripheral surface extends concentrically from the inner peripheral edge toward the outer peripheral edge. Preferably, the cylindrical body has translucency, and the surface light emitting portion is provided on the peripheral surface of the cylindrical body.
In addition, the said cylindrical body may be comprised by the some arc-shaped flat plate member formed with the elastic material being connected and curving. In that case, the transparent electrode of the surface emitting part can be formed on one surface of the flat plate member using the flat plate member as a transparent substrate.
