LIGHTING FIXTURE
PROBLEM TO BE SOLVED: To provide a lighting fixture that can improve durability against a heavy load.SOLUTION: The lighting fixture comprises a lower lighting body 10, an upper lighting body 20, an LED board 30, and a lens member 40. A concave part 12 of the lower lighting body comprises a first bottom surface 121. The upper lighting body comprises: a top plate part 21 opposed to the first bottom surface; and a columnar body part 22 protruding toward the first bottom surface from the top plate part. A tip of the columnar body part is fixed to the first bottom surface. The LED board 30 comprises a plurality of LED elements 31 arranged annularly around the columnar body part, and emits illumination light toward the top plate part from the first bottom surface. The lens member comprises a lens body 41, an annular light incident part 42, and an annular light emitting part 43. The lens body is made of a translucent material, and comprises an opening part through which the columnar body part penetrates. The light incident part is provided at one end part of the lens body, and opposed to a plurality of point light sources. The light emitting part is provided at an outer peripheral edge part of another end part of the lens body, and emits the illumination light.SELECTED DRAWING: Figure 5
【課題】重量物に対する耐久性を向上させることができる灯器を提供する。【解決手段】上記灯器は、下部灯体１０と、上部灯体２０と、ＬＥＤ基板３０と、レンズ部材４０とを具備する。下部灯体の凹部１２は、第１の底面１２１を有する。上部灯体は、第１の底面に対向する天板部２１と、天板部から第１の底面に向かって突出する柱体部２２とを有する。柱体部の先端は、第１の底面に固定される。ＬＥＤ基板３０は、上記柱体部の周囲に環状に配置された複数のＬＥＤ素子３１を有し、第１の底面から天板部に向かって照明光を出射する。レンズ部材は、レンズ本体４１と、環状の光入射部４２と、環状の光出射部４３とを有する。レンズ本体は、透光性材料で構成され、柱体部が貫通する開口部を有する。光入射部は、レンズ本体の一端部に設けられ、複数の点光源と対向する。光出射部は、レンズ本体の他端部の外周縁部に設けられ、照明光を出射する。【選択図】図５
