In this configuration, a lighting device is attached to the front side of the disk-shaped chassis of the instrument body, and an annular fluorescent lamp is disposed on the front side of the lighting device.

しかしながら、この構成では、照明器具を壁面に取り付けた状態で、蛍光ランプが垂直状に配置されるため、上下方向への配光の効果が小さいとともに、蛍光ランプと点灯装置とを重ねて配置するため、照明器具の厚さ寸法が大きくなる問題を有している。 However, in this configuration, since the fluorescent lamp is arranged vertically with the lighting fixture attached to the wall surface, the effect of light distribution in the vertical direction is small, and the fluorescent lamp and the lighting device are arranged in an overlapping manner. For this reason, there is a problem that the thickness dimension of the lighting fixture is increased.

この点、ランプが壁面から水平に突出するように支持する構成が知られている(例えば、非特許文献１参照。)。この構成では、照明器具は、本体と、この本体を壁面などに取り付ける取付金具と、本体を覆うカバーとを備えている。そして、本体は、垂直状の板部と、この垂直状の板部に固定された水平状の板部とを備え、垂直状の板部が取付金具を介して壁面などに取り付けられる。また、水平状の板部の上側には、点灯装置が取り付けられ、水平状の板部の下側には、円環状の蛍光ランプが取り付けられている。 In this regard, a configuration is known in which the lamp is supported so as to protrude horizontally from the wall surface (see, for example, Non-Patent Document 1). In this configuration, the lighting fixture includes a main body, a mounting bracket for attaching the main body to a wall surface, and a cover that covers the main body. The main body includes a vertical plate portion and a horizontal plate portion fixed to the vertical plate portion, and the vertical plate portion is attached to a wall surface or the like via a mounting bracket. A lighting device is attached to the upper side of the horizontal plate portion, and an annular fluorescent lamp is attached to the lower side of the horizontal plate portion.

しかしながら、この構成では、点灯装置と蛍光ランプとが上下に重ねて配置されるため、上下方向の厚さ寸法が大きくなる問題を有している。また、本体は、壁面用の取付金具及び梁用の取付金具を介して壁面あるいは梁に取り付けられ、いずれの場合も取付金具が必要であるため、部品点数が増加し、取付作業の作業性が悪い問題を有している。さらに、取付金具と本体との接続作業については、本体の水平状の板部に沿った狭い空間でねじ止めなどの作業をする必要があり、作業性が悪い問題を有している。

次いで、予め点灯装置15を取り付けた支持体14を、器具本体12に係合しねじ止めして取り付ける。この作業は、支持体14の当接支持部60を器具本体12の取付板部31に当接した状態から、支持体14を下方にスライドさせ、図６に示すように、係合部57を係合受部44に挿入するとともに、係止部58を係止受部46の上側に載置する。この状態で、係合部57と係合受部44との係合により支持体14が器具本体12に位置決めして仮止めされ、さらに、当接支持部60が長い寸法で取付板部31に当接して支持体14が器具本体12に安定して仮止めされる。 Next, the support body 14 to which the lighting device 15 is previously attached is engaged with the instrument main body 12 and fixed with screws. In this operation, the support 14 is slid downward from the state in which the contact support 60 of the support 14 is in contact with the mounting plate 31 of the instrument body 12, and the engagement portion 57 is moved as shown in FIG. While being inserted into the engagement receiving portion 44, the locking portion 58 is placed on the upper side of the locking receiving portion 46. In this state, the support 14 is positioned and temporarily fixed to the instrument body 12 by the engagement between the engagement portion 57 and the engagement receiving portion 44, and the contact support portion 60 has a long dimension to the mounting plate portion 31. By abutting, the support 14 is temporarily fixed to the instrument body 12 stably.

そして、上側から、係止部58の固定孔59にねじである固定具48を挿入し、係止受部46のねじ孔47に螺合して締め付けることにより、支持体14が器具本体12に強固に固定される。器具本体12の上方には、作業に干渉する部材は存在せず、固定具48のねじ込み作業は広い空間で容易に行われる。 Then, from above, a fixing tool 48, which is a screw, is inserted into the fixing hole 59 of the locking portion 58, and screwed into the screw hole 47 of the locking receiving portion 46 and tightened, whereby the support 14 is attached to the instrument body 12. It is firmly fixed. There is no member interfering with the work above the instrument body 12, and the screwing work of the fixture 48 is easily performed in a wide space.

次いで、電源線を端子台に接続するとともに、ランプホルダ18にランプＬを装着し、口金部64にランプソケット16を接続することにより、本体ユニット21が完成する。 Next, the power supply line is connected to the terminal block, the lamp L is mounted on the lamp holder 18, and the lamp socket 16 is connected to the base 64, thereby completing the main unit 21.

そして、この本体ユニット21の前側から、カバー体22を被せ、このカバー体22の開口部74を取付板部31に嵌合した状態で、カバー体22の取付部77に化粧ねじ24を挿入し、この化粧ねじ24を、本体ユニット21を構成する器具本体12のケース体取付部49のねじ孔50に螺合して締め付けることにより、カバー体22が本体ユニット21に取り付けられ、照明器具10が完成する。 Then, the cover body 22 is covered from the front side of the main body unit 21, and the decorative screw 24 is inserted into the attachment portion 77 of the cover body 22 in a state where the opening 74 of the cover body 22 is fitted to the attachment plate portion 31.

Complete.

また、上記の工程と逆の工程を採ることにより、保守作業などが行われる。 Moreover, maintenance work etc. are performed by taking the reverse process to said process.

一方、照明器具10を梁Ｂに設置する際は、まず、梁Ｂに取付金具26を取り付ける。この取付作業は、電源線を取付金具26で覆うようにして、電線配置空間97に電源線を配置しつつ、梁Ｂの前面に器具本体取付部81の垂直補強フランジ85を沿わせ、梁Ｂの上面に水平取付部82の固定板部94を沿わせて当接する。そして、上側から固定板部94の固定孔95に上側から取付固定具であるビスを挿入し、梁Ｂにセルフタッピングさせてねじ込み、梁Ｂの上面に水平取付部82を固定して、取付金具26を梁Ｂに締め付け固定する。 On the other hand, when installing the luminaire 10 on the beam B, first, the mounting bracket 26 is attached to the beam B. In this mounting operation, the power supply line is covered with the mounting bracket 26 so that the power supply line is disposed in the electric wire arrangement space 97, and the vertical reinforcing flange 85 of the instrument body mounting portion 81 is placed along the front surface of the beam B. The fixing plate portion 94 of the horizontal mounting portion 82 is in contact with the top surface of the horizontal mounting portion 82. Then, a screw, which is a mounting fixture, is inserted from above into the fixing hole 95 of the fixing plate portion 94 from above, is screwed by self-tapping onto the beam B, and the horizontal mounting portion 82 is fixed to the upper surface of the beam B, and the mounting bracket Tighten 26 to beam B and fix.

次いで、取付金具26の配線用切欠部86を介して、電源線を器具本体12の電線挿通部36に挿入して前側に引き出すとともに、取付金具26を器具本体12の取付凹部33に嵌め込む。そして、取付金具26に予め緩やかに螺合して取り付けた取付ねじ88を、器具本体12の取付金具取付部37の挿入部37aに挿入した状態で、器具本体12を下方にスライドさせることにより、取付ねじ88が取付金具取付部37の溝部44aに係止され、取付金具26に器具本体12が位置決めして仮止めされる。そして、各取付ねじ88を締め付けることにより、取付金具26の器具本体取付部81が取付凹部33に取り付けられ、取付金具26に器具本体12が強固に固定される。 Next, the power supply line is inserted into the wire insertion part 36 of the instrument body 12 through the wiring notch 86 of the attachment bracket 26 and pulled out to the front side, and the attachment bracket 26 is fitted into the attachment recess 33 of the instrument body 12. Then, by sliding the instrument body 12 downward in a state where the mounting screw 88 that is gently screwed into the mounting bracket 26 in advance is inserted into the insertion part 37a of the mounting bracket attachment part 37 of the instrument body 12, The mounting screw 88 is locked in the groove 44a of the mounting bracket mounting portion 37, and the instrument body 12 is positioned and temporarily fixed to the mounting bracket 26. Then, by tightening each mounting screw 88, the instrument body mounting portion 81 of the mounting bracket 26 is mounted in the mounting recess 33, and the instrument body 12 is firmly fixed to the mounting bracket 26.

続いて、器具本体12に支持体14を取り付ける作業以下は、上記の壁面Ｗに取り付ける作業と同一である。 Subsequently, the operation for attaching the support 14 to the instrument main body 12 is the same as the operation for attaching to the wall surface W described above.

そして、このように設置された照明器具10について、電源線から電力を供給し、ランプＬを点灯させると、ランプＬの発光部63から照射された光について、一部は反射面部53で反射させ、カバー体22の下側透光部71から下方に拡散しつつ配光が行われるとともに、カバー体22の上側透光部72から上方に拡散しつつ配光が行われる。 And about the lighting fixture 10 installed in this way, when electric power is supplied from a power supply line and the lamp L is turned on, part of the light emitted from the light emitting portion 63 of the lamp L is reflected by the reflecting surface portion 53. Light distribution is performed while diffusing downward from the lower light transmitting portion 71 of the cover body 22, and light distribution is performed while diffusing upward from the upper light transmitting portion 72 of the cover body 22.

このように、本実施の形態の照明器具10によれば、壁面Ｗ及び梁Ｂに取り付けできる壁面Ｗ取付形の照明器具12について、垂直状の被取付面である壁面Ｗに沿って取り付けられる器具本体12を備える構成であって、環状の発光部63が水平状とになるようにランプＬを支持板部51で支持したため、上下方向の配光を有効にできる。 Thus, according to the luminaire 10 of the present embodiment, the luminaire 12 attached to the wall surface W and the beam B can be attached along the wall surface W which is a vertical attached surface. Since the lamp L is supported by the support plate 51 so that the annular light emitting portion 63 is horizontal, the light distribution in the vertical direction can be made effective.

そして、環状のランプＬの内側に位置しかつランプＬと同じ側である支持板部51の下面に点灯装置15を支持したため、ランプＬと点灯装置15とを上下に重ねる構成に比べ、照明器具10を薄型化できるとともに、点灯装置15により光が妨げられず、上下に有効に配光できる。 Further, since the lighting device 15 is supported on the lower surface of the support plate 51 located on the inner side of the annular lamp L and on the same side as the lamp L, the luminaire is compared with a configuration in which the lamp L and the lighting device 15 are vertically stacked. 10 can be reduced in thickness, and the lighting device 15 does not block light and can effectively distribute light up and down.

また、ランプＬは、発光部63が支持板部51の下方に位置し、かつ、この支持板部51の上方から見て、発光部63の面積の半分以上が支持板部51から露出するようにしたため、下方のみならず、上方にも効率良く配光が確保され、照明効果を向上できる。 In the lamp L, the light emitting portion 63 is positioned below the support plate portion 51, and when viewed from above the support plate portion 51, more than half of the area of the light emitting portion 63 is exposed from the support plate portion 51. Therefore, the light distribution is efficiently ensured not only below but also above, and the illumination effect can be improved.

また、支持板部51は、ランプＬに対向して反射面部53を備えるとともに、この反射面部53に対向するようにランプＬの口金部64を配置したため、反射面部53による反射と、下側透光部71の拡散により、発光しない口金部64の部分が暗く見えることを抑制し、照明効果を向上できる。 Further, since the support plate portion 51 includes the reflection surface portion 53 facing the lamp L, and the base portion 64 of the lamp L is disposed so as to face the reflection surface portion 53, the reflection by the reflection surface portion 53 and the lower transparent portion are arranged. Due to the diffusion of the light portion 71, the portion of the base portion 64 that does not emit light can be suppressed from appearing dark, and the illumination effect can be improved.

また、支持体14は、係合受部44に上側から挿入して係合される係合部57と、係止受部46の上側に重ねられる係止部58とを備え、固定具48により係止受部46と係止部58とを固定する構成としたため、器具本体12と支持体14とを容易に着脱できる。そこで、器具本体12から支持体14を取り外し、作業空間を確保した状態で、前方からの作業で器具本体12を壁面Ｗに作業性良く取り付けできるとともに、メンテナンス作業も容易にできる。また、支持体14は、器具本体12に上側から組み合わせることにより、係合及び係止されるとともに、上側を作業空間として、固定具48により係止受部46と係止部58とを固定する作業を行うことができ、支持体14を器具本体12に作業性良く強固に取り付けできる。 Further, the support body 14 includes an engagement portion 57 that is inserted into and engaged with the engagement receiving portion 44 from above, and a locking portion 58 that is superimposed on the upper side of the locking receiving portion 46. Since the locking receiving portion 46 and the locking portion 58 are fixed, the instrument body 12 and the support body 14 can be easily attached and detached. Thus, the support body 14 can be removed from the instrument body 12 to secure the work space, so that the instrument body 12 can be attached to the wall surface W with good workability from the front and maintenance work can be facilitated. Further, the support body 14 is engaged and locked by being combined with the instrument main body 12 from above, and the locking receiving portion 46 and the locking portion 58 are fixed by the fixture 48 with the upper side as a work space. Work can be performed, and the support 14 can be firmly attached to the instrument body 12 with good workability.

Appearance can be maintained. Thus, when attaching the lighting fixture 10 to the wall surface W, it is not necessary to use the mounting bracket 26, the number of parts can be reduced, the configuration can be simplified, and the manufacturing cost can be reduced.

一方、照明器具12を梁Ｂに取り付ける場合には、取付金具26の水平取付部82を梁Ｂの上面に固定するとともに、この取付金具26の器具本体取付部81を取付凹部33に取り付けることにより、照明器具10を容易に強固に設置できる。この場合には、取付金具26に、器具本体取付部81から水平取付部82に連続する電線配置空間97を設けて配線スペースを確保したため、電線である電源線を保護しつつ、器具本体12の取付板部31を梁Ｂの垂直面に密着して配置できる。 On the other hand, when attaching the lighting fixture 12 to the beam B, the horizontal mounting portion 82 of the mounting bracket 26 is fixed to the upper surface of the beam B, and the fixture body mounting portion 81 of the mounting bracket 26 is attached to the mounting recess 33. The lighting apparatus 10 can be easily and firmly installed. In this case, the mounting bracket 26 is provided with the electric wire arrangement space 97 continuous from the instrument main body mounting portion 81 to the horizontal mounting portion 82 to secure the wiring space. The mounting plate portion 31 can be disposed in close contact with the vertical surface of the beam B.

なお、上記の実施の形態では、ランプＬは、略四角環状の蛍光ランプを用いたが、円環状の蛍光ランプを用いることもでき、複数のランプＬを同心状に配置することもできる。 In the above embodiment, the lamp L is a substantially square-shaped fluorescent lamp, but an annular fluorescent lamp can also be used, and a plurality of lamps L can be arranged concentrically.
