しかしながら、特許文献１に記載の照明器具の光源部は照射側にカバー部を備えている。カバー部は、光源部が器具本体部に照射側と反対側の一部を凹部に挿入し取り付けられた時に、凹部の開口端縁と隙間がないように重なる延出部を有している。その為、光源部を器具本体部から取り外す時は、作業者が光源部を掴む（指を引っ掛ける）箇所がなく作業がし難かった。 However, the light source part of the lighting fixture described in Patent Document 1 includes a cover part on the irradiation side. The cover portion has an extension portion overlapping with the opening end edge of the concave portion so that there is no gap when the light source portion is attached to the concave portion by inserting a part of the light source portion opposite to the irradiation side into the concave portion. Therefore, when the light source unit is removed from the instrument body, there is no place where the operator grips the light source unit (hooks the finger) and the operation is difficult.

また特許文献２あるいは特許文献３に記載されている照明器具は、光源部の長手側辺と凹部の長手側壁部との間に隙間が形成されるように光源部が器具本体部に取り付けられている。光源部は、この隙間に専用の治具を挿し込むことで器具本体部から取り外すことができるが、専用の治具を必要とする為、作業に手間がかかった。また、光源部と凹部の間に形成された隙間が、光源部を発光させた際に暗がりになり、意匠性の点で課題があった。 Further, in the lighting fixture described in Patent Document 2 or Patent Document 3, the light source unit is attached to the tool main body so that a gap is formed between the longitudinal side of the light source unit and the longitudinal side wall of the recess. There is. The light source unit can be removed from the tool main body by inserting a dedicated jig into this gap, but since it requires a dedicated jig, the operation took time and effort. Moreover, when the light source part was made to light-emit, the clearance gap formed between the light source part and the recessed part became dark, and there existed a subject by the point of the designability.

本発明は、器具本体と光源の脱着が容易にできるとともに、器具本体に光源を取り付けたときに意匠性を向上させる照明器具の提供を目的とする。 An object of the present invention is to provide a luminaire capable of facilitating the attachment and detachment of an instrument main body and a light source and improving the design when the light source is attached to the instrument main body.

As shown in FIG. 3, the light source unit 200 includes a connection fitting 250 on which the spring portion 130 provided in the tool body 100 is hooked, and a power supply device 260 attached to the holding portion 220 and supplying power to the light emitting element substrate 210. .

発光素子基板２１０は、長尺に形成された基板２１１と、基板２１１に直線状に実装される複数の発光素子２１２とれる複数の発光素子２１２を備えている。なお、発光素子２１２を直線状に実装する列は一列でも良く、複数列でも良い。 The light emitting element substrate 210 includes a long substrate 211 and a plurality of light emitting elements 212 which can be a plurality of light emitting elements 212 linearly mounted on the substrate 211. Note that one row or a plurality of rows may be used to linearly mount the light emitting elements 212.

保持部２２０は、発光素子基板２１０が取り付けられる略矩形状をした取付部２２１と、取付部２２１の長手両側辺より発光素子基板２１０が取り付けられる面２２１ａから裏面２２１ｂの方向に立設した第一の側面部２２２−１、第二の側面部２２２−２とを有している。 The holding portion 220 is a substantially rectangular attachment portion 221 to which the light emitting element substrate 210 is attached, and a first erected from a longitudinal side of the attachment portion 221 from the surface 221 a to which the light emitting element substrate 210 is attached to the back surface 221 b. And a second side portion 222-2.

カバー部２３０は、図７に示すよう中心軸１１を対称軸として略対象に形成されている。よって、片側に関して説明するが、説明する構成は中心軸１１に線対称として対になるよう形成されている。カバー部２３０は、拡散部２３１、カバー側壁部２３２、第一の支持部である傾斜保持部２３３、第二の支持部である支持部２３４を備える。
（１）拡散部２３１は、円弧形状であり発光素子基板２１０から照射される光を拡散する。
（２）カバー側壁部２３２は、拡散部２３１の両端から対になるよう配設され、カバー部２３０の側面に位置する。
（３）傾斜保持部２３３は、保持部２２０の第一の側面部２２２−１、第二の側面部２２２−２の先端と当接する第一の支持部である。
（４）支持部２３４は、取付部２２１に当接する第二の支持部である。 As shown in FIG. 7, the cover portion 230 is formed substantially symmetrically with the central axis 11 as an axis of symmetry. Therefore, although it demonstrates regarding one side, the structure to be demonstrated is formed so that it may be paired as line symmetry with respect to the central axis 11. The cover portion 230 includes a diffusion portion 231, a cover side wall portion 232, an inclined holding portion 233 which is a first support portion, and a support portion 234 which is a second support portion.
(1) The diffusion part 231 has an arc shape and diffuses the light emitted from the light emitting element substrate 210.
(2) The cover side wall portion 232 is disposed in a pair from both ends of the diffusion portion 231, and is positioned on the side surface of the cover portion 230.
(3) The inclined holding portion 233 is a first support portion that abuts on the tip of the first side surface portion 222-1 and the second side surface portion 222-2 of the holding portion 220.
(4) The support portion 234 is a second support portion that abuts on the attachment portion 221.

拡散部２３１は、発光素子基板２１０が照射する光を透過させ拡散させるものであり、発光素子基板２１０を覆うように円弧形状をしている。図８に示すように、拡散部２３１は、カバー側壁部２３２の先端部２３２ｂである端部Ａの反対側となる端部Ｂ側に位置しており、対になるカバー側壁部２３２の端部Ｂ、端部Ｂを繋ぐように配設されている。言い換えれば、カバー側壁部２３２は端部Ａと端部Ｂとの間に形成されている。 The diffusion part 231 transmits and diffuses the light emitted from the light emitting element substrate 210, and has a circular arc shape so as to cover the light emitting element substrate 210. As shown in FIG. 8, the diffusion portion 231 is located on the end B side opposite to the end A which is the tip end portion 232 b of the cover side wall portion 232, and the end portion of the cover side wall portion 232 to be paired B, arranged so as to connect the end B. In other words, the cover side wall portion 232 is formed between the end A and the end B.

カバー側壁部２３２は拡散部２３１の両端（端部Ｂ）から対になるよう配設され、器具本体１００の凹部１１１の第一の側壁部１１３−１、第二の側壁部１１３−２と略平行に形成されている。また、対になるカバー側壁部２３２の外側の面の距離である寸法Ｌ１（図９）は、凹部１１１の開口部１１１ａ（図２の矩形ａｂｃｄ）の巾である寸法Ｌ２（対向する第一の側壁部１１３−１と、第二の側壁部１１３−２との短手方向の距離）に対して、器具本体１００の凹部１１１に挿入可能に略同等の寸法に形成される。なお、挿入可能に略同等の寸法とは、光源ユニット２００が凹部１１１との間に形成される隙間をなるべく抑え、挿入できる寸法である。例えば寸法Ｌ１が５９ｍｍに対して寸法Ｌ２が６０ｍｍなどである。つまり、照明器具３００は、器具本体１００に光源ユニット２００が取り付けられた状態において、凹部１１１の短手方向Ｙ（図９）における第一の側壁部１１３−１の内側面１１３−１ａと第二の側壁部１１３−２の内側面１１３−２ａとの距離である凹部内側巾寸法Ｌ２から、カバー部２３０の短手方向Ｙにおける一方の先端部２３２ｂの外側面２３２ｃと他方の先端部２３２ｂの外側面２３２ｃとの距離である先端部外側巾寸法Ｌ１を引いた寸法が、０ｍｍ以上３ｍｍ以下である。つまり、照明器具３００は、器具本体１００に光源ユニット２００が取り付けられた状態において、図９のＡ−Ａ断面において、左右の各隙間を同じとすれば、各隙間は０ｍｍ以上１．５ｍｍ以下の範囲である。 The cover side wall portion 232 is disposed so as to be paired from both ends (end portion B) of the diffusion portion 231, and is substantially the same as the first side wall portion 113-1 and the second side wall portion 113-2 of the recess 111 of the instrument body 100. It is formed in parallel. Further, a dimension L1 (FIG. 9) which is a distance of the outer surface of the cover side wall portion 232 to be paired is a dimension L2 (a facing first) which is a width of the opening 111a (a rectangle abcd in FIG. 2) With respect to the distance in the lateral direction between the side wall portion 113-1 and the second side wall portion 113-2, it is formed to have substantially the same size so as to be insertable into the recess 111 of the instrument body 100. In addition, the dimension which can be inserted substantially and is equivalent is a dimension which can suppress the clearance gap formed between the light source unit 200 and the recessed part 111 as much as possible, and can insert it. For example, the dimension L2 is 60 mm, for example, while the dimension L1 is 59 mm. That is, in the state in which the light source unit 200 is attached to the instrument main body 100, the luminaire 300 has the second inner surface 113-1a of the first side wall 113-1 and the second In the recess inner width L2, which is the distance between the side wall 113-2 and the inner surface 113-2a of the side wall 113-2, the outer surface 232c of one end portion 232b and the outside of the other end portion 232b in the short direction Y of the cover portion 230 A dimension obtained by subtracting the tip outer width dimension L1 which is a distance to the side surface 232c is 0 mm or more and 3 mm or less. That is, in the state where the light source unit 200 is attached to the instrument main body 100, if the left and right gaps are the same in the cross section AA in FIG. 9, each of the gaps is 0 mm or more and 1.5 mm or less It is a range.
