Description

照明装置、支持部材及び表示装置LIGHTING DEVICE, SUPPORT MEMBER AND DISPLAY DEVICE
　本発明は、照明装置、支持部材及び表示装置に関する。 The present invention relates to a lighting device, a support member, and a display device.
　従来の技術として、パイプ内に発光ダイオード（ＬＥＤ）を両面実装した回路基板を収容する照明装置が提案されている（例えば、特許文献１参照）。 As a conventional technique, there has been proposed a lighting device that houses a circuit board in which light-emitting diodes (LEDs) are mounted on both sides in a pipe (see, for example, Patent Document 1).
　特許文献１に開示された照明装置は、光を拡散する拡散剤を含むパイプと、パイプ内に収容される回路基板とを有し、回路基板の両面にはＬＥＤが実装され基板はパイプ内壁の凹部に支持される。ＬＥＤは回路基板表面及び裏面から双方向に発光するため、パイプ長手方向に直交する断面において回路基板をパイプ中心に配置するようにパイプ内周の凹部は互いに最も離れた位置に設けられる。 The lighting device disclosed in Patent Document 1 includes a pipe including a diffusing agent that diffuses light, and a circuit board accommodated in the pipe. LEDs are mounted on both sides of the circuit board, and the board is formed on the inner wall of the pipe. Supported by the recess. Since the LED emits light bi-directionally from the front and back surfaces of the circuit board, the recesses on the inner periphery of the pipe are provided at positions farthest from each other so that the circuit board is arranged at the center of the pipe in a cross section orthogonal to the longitudinal direction of the pipe.
