Description

この発明は、照明器具に関する。 The present invention relates to a lighting fixture.

従来より、ＬＥＤモジュールおよび直流電源装置を内蔵する長尺状の光源部と、この光源部の一部が挿入される凹部を有する器具本体部とを備える照明器具であって、光源部が器具本体部に着脱自在に取り付けられる照明器具がある（例えば、特許文献１、２、３）。 Conventionally, there is provided a lighting device including a long light source part having an LED module and a DC power supply unit built therein, and a fixture main body part having a recess into which a part of the light source part is inserted. There is a lighting fixture that is detachably attached to the unit (for example, Patent Documents 1, 2, and 3).

特開２０１４−０７８５１１号公報JP, 2014-078511, A 特開２０１１−１４２０６３号公報JP, 2011-142063, A 特開２０１２−００３９９３号公報JP2012-003993A

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 unit of the lighting device described in Patent Document 1 includes a cover unit on the irradiation side. The cover portion has an extending portion that overlaps with the opening end edge of the concave portion so that there is no gap when the light source portion is inserted into the concave portion of the instrument body portion on the side opposite to the irradiation side and attached. Therefore, when removing the light source unit from the instrument body, it is difficult for the worker to work because there is no place for the operator to grasp the light source unit (hook his/her finger).

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 device described in Patent Document 2 or Patent Document 3, the light source unit is attached to the main body of the device such that a gap is formed between the long side of the light source unit and the long side wall of the recess. There is. The light source section can be removed from the instrument main body section by inserting a dedicated jig into this gap, but it requires a dedicated jig, which takes time and effort. In addition, the gap formed between the light source unit and the recess becomes dark when the light source unit emits light, and there is a problem in terms of 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。 It is an object of the present invention to provide a lighting fixture that can be easily attached to and detached from a fixture body and a light source and that improves the designability when the light source is attached to the fixture body.

＜＊＊＊構成の説明＊＊＊＞
はじめに、図１〜図１０を参照して照明器具３００の各部の構成を説明する。照明器具３００は、長尺状の器具本体１００と、器具本体１００に着脱可能に取り付けられる長尺状の光源ユニット２００とを備える。光源ユニット２００は、器具本体１００の後述する凹部１１１に一部を挿入しながら、着脱可能に取り付けられる。器具本体１００、光源ユニット２００はいずれも長尺状であるが、その長手方向を長手方向Ｘとし、長手方向Ｘに対する短手方向を短手方向Ｙ（図１）とする。 <Description of structure ***>
First, the configuration of each part of the lighting fixture 300 will be described with reference to FIGS. 1 to 10. The lighting fixture 300 includes a long fixture body 100 and a long light source unit 200 detachably attached to the fixture body 100. The light source unit 200 is detachably attached while a part of the light source unit 200 is inserted into a recessed portion 111 of the instrument body 100 described later. The instrument main body 100 and the light source unit 200 are both elongated, but the longitudinal direction thereof is the longitudinal direction X, and the lateral direction with respect to the longitudinal direction X is the lateral direction Y (FIG. 1).

図６に示すように、光源ユニット２００は、発光素子基板２１０、保持部２２０、カバー部２３０、光源蓋部２４０を備える。
（１）発光素子基板２１０は発光素子２１２を有する。発光素子基板２１０は、長尺に形成された基板２１１に複数の発光素子２１２が実装される。この実施の形態では発光素子２１２はＬＥＤである。
（２）保持部２２０は、発光素子基板２１０が取り付けられる。図９に示すように、保持部２２０は、平板状をなす取付部２２１であって平板部１１２に対向する面２２１ｂの裏面２２１ａに発光素子基板２１０が取り付けられる取付部２２１を有する。
（３）カバー部２３０は発光素子基板２１０を覆うように保持部２２０に取り付けられる。カバー部２３０は保持部２２０に取り付けられて保持部２２０に保持される。カバー部２３０は、拡散部２３１と、対になるように設けられたカバー側壁部２３２とを有する。拡散部２３１は、平板部１１２の長手方向Ｘに沿う長尺状をなし発光素子基板２１０を覆う。対となるカバー側壁部２３２は、拡散部２３１の長手方向Ｘに沿う一方の端部２３１ａと他方の端部２３１ｂとから間に保持部２２０を挟んでそれぞれ平板部１１２の方向に立ち上がる側壁部であり、対となるカバー側壁部２３２である。カバー側壁部２３２の対は、各カバー側壁部２３２の一部につかみ部２３２ａが形成されている。平板部１１２の方向は、保持部２２０の一方の面２２１ａから一方の面２２１ａの反対側の他方の面２２１ｂに向かう方向である。
（４）光源蓋部２４０は光源ユニット２００の長手方向両端を塞ぐ。
（５）また、光源ユニット２００は、本体側連結部１３００の相手部品として保持部２２０に配置され、本体側連結部１３００と連結し、連結によって生じる弾性力によって光源ユニット２００の一部を凹部１１１に収納する光源側連結部２５００を備える。この実施の形態では光源側連結部２５００は連結金具２５０である。図１１で後述するように、光源ユニット２００は、つかみ部２３２ａをつかまれて引っ張られた場合、光源側連結部２５００が本体側連結部１３００との弾性力による連結状態を維持した状態で、凹部１１１に収納された一部が凹部１１１から引き出される。図３に示すように、光源ユニット２００は器具本体１００に設けられたバネ部１３０が引っ掛けられる連結金具２５０と、保持部２２０に取り付けられ発光素子基板２１０に電力を供給する電源装置２６０とを備える。 As shown in FIG. 6, the light source unit 200 includes a light emitting element substrate 210, a holding portion 220, a cover portion 230, and a light source lid portion 240.
(1) The light emitting element substrate 210 has the light emitting element 212. In the light emitting element substrate 210, a plurality of light emitting elements 212 are mounted on a long substrate 211. In this embodiment, the light emitting element 212 is an LED.
(2) The light emitting element substrate 210 is attached to the holder 220. As shown in FIG. 9, the holding portion 220 has a mounting portion 221 having a flat plate shape, and the mounting portion 221 on which the light emitting element substrate 210 is mounted on the back surface 221 a of the surface 221 b facing the flat plate portion 112.
(3) The cover part 230 is attached to the holding part 220 so as to cover the light emitting element substrate 210. The cover part 230 is attached to the holding part 220 and held by the holding part 220. The cover part 230 has a diffusion part 231 and a cover side wall part 232 provided so as to be paired. The diffusion part 231 has a long shape along the longitudinal direction X of the flat plate part 112 and covers the light emitting element substrate 210. The pair of cover side wall portions 232 is a side wall portion that rises in the direction of the flat plate portion 112 with the holding portion 220 sandwiched between one end portion 231a and the other end portion 231b along the longitudinal direction X of the diffusion portion 231. There is a pair of cover side wall portions 232. The pair of cover side wall portions 232 has a grip portion 232a formed in a part of each cover side wall portion 232. The direction of the flat plate portion 112 is a direction from one surface 221a of the holding portion 220 to the other surface 221b opposite to the one surface 221a.
(4) The light source lid portion 240 closes both longitudinal ends of the light source unit 200.
(5) Further, the light source unit 200 is disposed in the holding portion 220 as a counterpart component of the main body side connecting portion 1300, is connected to the main body side connecting portion 1300, and a part of the light source unit 200 is recessed by the elastic force generated by the connection. And a light source side connection part 2500 to be housed in. In this embodiment, the light source side connection part 2500 is the connection fitting 250. As will be described later with reference to FIG. 11, in the light source unit 200, when the grip portion 232 a is gripped and pulled, the light source side connecting portion 2500 maintains the connection state by the elastic force with the main body side connecting portion 1300, and the concave portion 111. The part stored in is pulled out from the concave portion 111. As shown in FIG. 3, the light source unit 200 includes a connecting fitting 250 to which the spring portion 130 provided on the fixture body 100 is hooked, and a power supply device 260 that is attached to the holding portion 220 and supplies electric 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 are a plurality of light emitting elements 212 linearly mounted on the substrate 211. Note that the row in which the light emitting elements 212 are linearly mounted may be a single row or a plurality of rows.

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 has a substantially rectangular mounting portion 221 to which the light emitting element substrate 210 is mounted, and a first standing portion that is erected from both sides of the mounting portion 221 in the direction from the surface 221a to which the light emitting element substrate 210 is mounted to the back surface 221b. It has a side surface part 222-1 and a second side surface part 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。 The cover part 230 is formed substantially symmetrically with the central axis 11 as the axis of symmetry, as shown in FIG. 7. Therefore, although one side will be described, the structure to be described is formed so as to be paired with respect to the central axis 11 in line symmetry. The cover part 230 includes a diffusion part 231, a cover side wall part 232, a tilt holding part 233 that is a first support part, and a support part 234 that is a second support part.
(1) The diffusion unit 231 has an arc shape and diffuses the light emitted from the light emitting element substrate 210.
(2) The cover side wall portions 232 are arranged in pairs from both ends of the diffusion portion 231, and are located on the side surface of the cover portion 230.
(3) The inclined holding portion 233 is a first supporting portion that comes into contact with the tips 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 the mounting 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 by the light emitting element substrate 210, and has an arc shape so as to cover the light emitting element substrate 210. As shown in FIG. 8, the diffusion part 231 is located on the end B side opposite to the end A which is the tip 232 b of the cover side wall 232, and the end of the pair of cover side walls 232. B and the end portion B are connected to each other. In other words, the cover side wall portion 232 is formed between the end portion A and the end portion 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 portions 232 are arranged so as to form a pair from both ends (end B) of the diffusion portion 231, and are 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, the dimension L1 (FIG. 9), which is the distance between the outer surfaces of the pair of cover side wall portions 232, is the dimension L2 (the first opposing surface) of the opening 111a (rectangle abcd in FIG. 2) of the recess 111. The side wall portion 113-1 and the second side wall portion 113-2 are formed to have substantially the same dimensions so that the side wall portion 113-1 and the second side wall portion 113-2 can be inserted into the recess 111 of the instrument body 100. It should be noted that the substantially insertable size is a size that allows the light source unit 200 to be inserted while suppressing a gap formed between the light source unit 200 and the recess 111 as much as possible. For example, the dimension L1 is 59 mm and the dimension L2 is 60 mm. That is, in the lighting fixture 300, in the state where the light source unit 200 is attached to the fixture main body 100, the inner side surface 113-1a of the first side wall portion 113-1 and the second side surface 113-1a of the recess 111 in the lateral direction Y (FIG. 9). From the recess inner side width dimension L2 which is the distance from the inner side surface 113-2a of the side wall portion 113-2, the outer surface 232c of the one tip portion 232b and the outside of the other tip portion 232b in the lateral direction Y of the cover portion 230. A dimension obtained by subtracting the tip end outer width dimension L1 which is the distance from the side surface 232c is 0 mm or more and 3 mm or less. That is, in the lighting fixture 300, in the state where the light source unit 200 is attached to the fixture main body 100, if the left and right gaps are the same in the AA cross section of FIG. 9, the gaps are 0 mm or more and 1.5 mm or less. It is a range.

また、カバー側壁部２３２は、光源ユニット２００が器具本体１００の凹部１１１に一部が収納された際に、凹部１１１の開口部１１１ａから外側に位置するつかみ部２３２ａを有している。図１０に示すように、光源ユニット２００は、器具本体１００への取付完了時に一部が凹部１１１に収納された状態において、カバー部２３０の各つかみ部２３２ａが、平板部１１２に対向する凹部１１１の開口部１１１ａから凹部１１１の外部へ露出すると共に、各カバー側壁部２３２の先端部２３２ｂが、凹部１１１に収納される。凹部１１１に収納される各カバー側壁部２３２の先端部２３２ｂは、各カバー側壁部２３２とともに開口部１１１ａを塞ぐ。また、光源ユニット２００は、器具本体１００への取付完了時に一部が凹部１１１に収納された状態において、各カバー側壁部２３２の先端部２３２ｂと各傾斜保持部２３３とが凹部１１１に収納され、凹部１１１に収納される各先端部２３２ｂは、各カバー側壁部２３２とともに、平板部１１２に対向する凹部１１１の開口部１１１ａを塞ぐ。図１０に示すように、各つかみ部２３２ａは、少なくとも一部が、発光素子２１２よりも第一の側壁部１１３−１が立ち上がる方向Ｚに位置する。これによって発光素子２１２の発した光を各つかみ部２３２ａで拡散できるので、照明効果を向上できる。光源ユニット２００は、各つかみ部２３２ａをつかまれて第一の側壁部１１３−１が立ち上がる方向Ｚ（図１０）に引っ張られた場合、凹部１１１に収納された一部が凹部１１１から引き出される（図１１）。対になるつかみ部２３２ａの外側の面の距離である寸法Ｌ３（図１０）は、つかみ部２３２ａが凹部１１１に挿入されないので、寸法Ｌ２と同じ寸法でも良い。 In addition, the cover side wall portion 232 has a grip portion 232a positioned outside the opening portion 111a of the recess 111 when the light source unit 200 is partially housed in the recess 111 of the instrument body 100. As shown in FIG. 10, when the light source unit 200 is partially accommodated in the recess 111 when the attachment to the instrument body 100 is completed, each grip portion 232 a of the cover portion 230 has the recess portion 111 facing the flat plate portion 112. While being exposed to the outside of the recess 111 from the opening 111a, the tip 232b of each cover side wall 232 is housed in the recess 111. The tip end portion 232b of each cover side wall portion 232 housed in the recess 111 closes the opening portion 111a together with each cover side wall portion 232.

＜＊＊＊効果の説明＊＊＊＞
本実施の形態では、カバー部２３０は、対になるカバー側壁部２３２の距離が、開口部１１１ａの第一の側壁部１１３−１と第二の側壁部１１３−２との距離に対して、器具本体１００の凹部１１１に挿入ができるように略同等の寸法に形成されている。この構成により、光源ユニット２００と器具本体１００との間に隙間による暗がりを防ぎ意匠性を向上できる。 <Explanation of the effect ***>
In the present embodiment, in the cover portion 230, the distance between the pair of cover side wall portions 232 is larger than the distance between the first side wall portion 113-1 and the second side wall portion 113-2 of the opening 111a. It is formed to have substantially the same dimensions so that it can be inserted into the recess 111 of the instrument body 100. With this configuration, it is possible to prevent the darkness due to the gap between the light source unit 200 and the instrument body 100, and improve the design.

本実施の形態では、カバー部２３０は、光源ユニット２００が器具本体１００に取り付けられた場合に、カバー側壁部２３２に形成されたつかみ部２３２ａが、開口部１１１ａの外側に露出する。よって、つかみ部２３２ａをつかめるので、光源ユニット２００を器具本体１００から容易に取り外すことができ、また、光源ユニット２００を器具本体１００に容易に装着することができる。 In this embodiment, when the light source unit 200 is attached to the instrument main body 100, the cover portion 230 has the grip portion 232a formed on the cover side wall portion 232 exposed to the outside of the opening portion 111a. Therefore, since the grip portion 232a can be grasped, the light source unit 200 can be easily removed from the instrument body 100, and the light source unit 200 can be easily attached to the instrument body 100.

本実施の形態では、照明器具３００は操作空間５００を有していることにより、光源ユニット２００の着脱作業時に、光源ユニット２００と凹部１１１との間、もしくは光源ユニット２００と開口縁部１１１ｂとの間に指などを挟むことを防止できるので、作業の安全性を向上できる。 In the present embodiment, since the lighting fixture 300 has the operation space 500, the light source unit 200 and the recess 111 or the light source unit 200 and the opening edge portion 111b are attached or detached when the light source unit 200 is attached or detached. Since it is possible to prevent fingers or the like from being caught in between, work safety can be improved.

本実施の形態では、対になる傾斜保持部２３３が内側斜めに形成されている。よって、カバー側壁部２３２を凹部１１１へ挿入する場合に、対になる傾斜保持部２３３のうちどちらか一方の傾斜保持部２３３及びその一方の傾斜保持部２３３の端部Ａ（先端部２３２ｂ）が、開口縁部１１１ｂに対して摺動して光源ユニット２００の装着のガイド機能を果たし、光源ユニット２００を器具本体１００に装着することが容易になる。 In the present embodiment, the pair of inclined holding portions 233 are formed obliquely inward. Therefore, when the cover side wall portion 232 is inserted into the concave portion 111, one of the pair of tilt holding portions 233 and the end portion A (the tip portion 232b) of the one tilt holding portion 233 is By sliding on the opening edge portion 111b, a guide function for mounting the light source unit 200 is achieved, and it becomes easy to mount the light source unit 200 on the instrument body 100.

図１４〜図１６を参照して、本実施の形態の変形例である。光源ユニット２００Ａ、２００Ａ−１、２００Ｂ、２００Ｂ−１、２００Ｃ、２００Ｃ−１を説明する。光源ユニット２００Ａ等は、光源ユニット２００に対してカバー部のつかみ部の形状が異なる。 It is a modification of the present embodiment with reference to FIGS. 14 to 16. The light source units 200A, 200A-1, 200B, 200B-1, 200C, 200C-1 will be described. The light source unit 200A and the like differ from the light source unit 200 in the shape of the grip portion of the cover portion.

図１４の（ａ）及び（ｂ）は、光源ユニット２００Ａ、カバー部２３０Ａ及び光源ユニット２００Ａ−１、カバー部２３０Ａ−１を示す。本実施の形態の変形例として、図１４の（ａ）に示すようなカバー部２３０Ａを備えた光源ユニット２００Ａでも良い。カバー部２３０Ａはカバー側壁部１２３２のつかみ部１２３２ａに、内側に凹んだつかみ凹部１２３２ｂが形成されている。つまり各つかみ部１２３２ａは、他方のつかみ部１２３２ａの方向に凹む形状のつかみ凹部１２３２ｂを有する。光源ユニット２００Ａは、つかみ部１２３２ａがつかみ凹部１２３２ｂを有していることにより、着脱するときの操作性が向上する。なお、図１４の（ａ）ではつかみ凹部１２３２ｂを傾斜保持部２３３側に設けている。これに限らず、図１４の（ｂ）に示すように、カバー側壁部１２３２−１におけるつかみ凹部１２３２ｂ−１を、拡散部２３１側に設けても、カバー部２３０Ａと同じ効果を得ることができる。なお、つかみ凹部は、光源ユニットの配光特性、意匠形状により、つかみ部の範囲内であれば、どこに設けても良く、つかみ部全体をつかみ凹部にしても良い。 14A and 14B show the light source unit 200A, the cover portion 230A, the light source unit 200A-1, and the cover portion 230A-1. As a modified example of the present embodiment, a light source unit 200A including a cover portion 230A as shown in FIG. 14A may be used. In the cover portion 230A, a grip portion 1232a of the cover side wall portion 1232 is formed with a grip concave portion 1232b that is recessed inward. That is, each grip portion 1232a has a grip recess 1232b that is recessed in the direction of the other grip portion 1232a. In the light source unit 200A, since the grip portion 1232a has the grip recess 1232b, the operability when attaching and detaching is improved. In addition, in FIG. 14A, the grip concave portion 1232b is provided on the side of the inclined holding portion 233. Not limited to this, as shown in FIG. 14B, even if the grip recess 1232b-1 in the cover side wall 1232-1 is provided on the diffusion part 231 side, the same effect as the cover 230A can be obtained. .. Note that the grip recess may be provided anywhere within the range of the grip depending on the light distribution characteristics of the light source unit and the design shape, and the entire grip may be the recess.

図１５の（ａ）及び（ｂ）は、光源ユニット２００Ｂ、カバー部２３０Ｂ及び光源ユニット２００Ｂ−１、カバー部２３０Ｂ−１を示す。本実施の形態の変形例として図１５の（ａ）に示すような、カバー部２３０Ｂを備えた光源ユニット２００Ｂでも良い。カバー部２３０Ｂは、つかみ部２２３２ａの拡散部２３１側につかみ凸部２２３２ｂを配設している。つまり各つかみ部２２３２ａは、他方のつかみ部２２３２ａの方向と反対方向に突き出る凸形状のつかみ凸部２２３２ｂを有する。光源ユニット２００Ｂは、つかみ部２２３２ａの拡散部２３１側につかみ凸部２２３２ｂを有していることにより、着脱するときの操作性を向上できる。また、拡散部２３１は、つかみ凸部２２３２ｂの外側端部に接続するよう形成されており、巾寸法（寸法Ｄ）を大きく形成できる。よって、下側から光源ユニット２００Ｂを見たときに、拡散部２３１が、カバー側壁部２２３２の目隠しとなり、意匠性を向上できる。なお、図１５の（ｂ）のように、操作性、意匠形状により、つかみ部２２３２ａの寸法を変更して、カバー側壁部２２３２−１に、つかみ凸部２２３２ｂ−１を有するつかみ部２２３２ａ−１を形成することとしても同じ効果を得ることができる。 15A and 15B show the light source unit 200B, the cover portion 230B, the light source unit 200B-1, and the cover portion 230B-1. As a modified example of the present embodiment, a light source unit 200B including a cover portion 230B as shown in FIG. 15A may be used. The cover portion 230B has a grip projection 2232b arranged on the side of the diffusion portion 231 of the grip portion 2232a. That is, each grip portion 2232a has a convex grip projection 2232b that protrudes in a direction opposite to the direction of the other grip portion 2232a. Since the light source unit 200B has the grip projection 2232b on the side of the diffusion part 231 of the grip 2232a, the operability at the time of attachment/detachment can be improved. Further, the diffusion portion 231 is formed so as to be connected to the outer end portion of the gripping convex portion 2232b, and the width dimension (dimension D) can be increased. Therefore, when the light source unit 200B is viewed from the lower side, the diffusion portion 231 becomes a blind of the cover side wall portion 2232, and the designability can be improved. As shown in FIG. 15B, the size of the grip portion 2232a is changed according to the operability and the design shape, and the grip portion 2232a-1 having the grip convex portion 2232b-1 is provided on the cover side wall portion 2322-1. The same effect can be obtained by forming.

図１６の（ａ）及び（ｂ）は、光源ユニット２００Ｃ、カバー部２３０Ｃ及び光源ユニット２００Ｃ−１、カバー部２３０Ｃ−１を示す。図１６の（ａ）に示すように、つかみ部を斜めに形成した傾斜操作部である傾斜立上部３２３２ｂが配設されたカバー部２３０Ｃを備えた光源ユニット２００Ｃでも良い。また、図１６（ｂ）に示すように、つかみ部を斜めに形成した傾斜操作部である傾斜立上部３２３２ｂ−１が配設されたカバー部２３０Ｃ−１を備えた光源ユニット２００Ｃ−１でも良い。カバー部２３０Ｃでは傾斜立上部３２３２ｂが開口縁部１１１ｂと離れており当接していないが、カバー部２３０Ｃ−１では傾斜立上部３２３２ｂ−１が開口縁部１１１ｂに当接している。傾斜立上部３２３２ｂ、３２３２ｇ−１を設けることで、より意匠性を向上できる。このように、各カバー側壁部３２３２は、他方のカバー側壁部３２３２の方向に傾斜して立ち上がる傾斜立上部３２３２ｂ、３２３２ｂ−１を備える。そして、各つかみ部３２３２ａ、３２３２ａ−１は、各傾斜立上部３２３２ｂ，３２３２ｂ−１の一部である。 16A and 16B show the light source unit 200C, the cover portion 230C, the light source unit 200C-1, and the cover portion 230C-1. As shown in FIG. 16A, the light source unit 200C may be provided with a cover portion 230C in which an inclined rising portion 3232b which is an inclined operation portion in which a grip portion is formed obliquely is arranged. Further, as shown in FIG. 16B, the light source unit 200C-1 may be provided with a cover portion 230C-1 in which an inclined rising portion 3232b-1 that is an inclined operation portion in which a grip portion is formed obliquely is arranged. .. In the cover portion 230C, the inclined rising portion 3232b is separated from the opening edge portion 111b and is not in contact with it, but in the cover portion 230C-1, the inclined rising portion 3232b-1 is in contact with the opening edge portion 111b. By providing the inclined rising portions 3232b and 3232g-1, the designability can be further improved. As described above, each cover side wall portion 3232 includes the inclined rising portions 3232b and 3232b-1 which are inclined and rise in the direction of the other cover side wall portion 3232. And each grip part 3232a, 3232a-1 is a part of each inclined rising part 3232b, 3232b-1.
