側面部３ａは、側壁部２１のうち、第１側壁部２１ａと第２側壁部２１ｂとの段差部分を覆う。側面部３ａは第１開口２４から第２開口２３に向かう方向に沿って延びる。このように、カバー３は筐体２の上端部に沿った形状をしており、第２開口２３を塞ぐ。 The side surface portion 3a covers the stepped portion between the first side wall portion 21a and the second side wall portion 21b in the side wall portion 21. The side surface portion 3a extends from the first opening 24 toward the second opening 23. As described above, the cover 3 has a shape along the upper end portion of the housing 2 and closes the second opening 23.

図１、２に示されるように、端子台４は筐体２およびカバー３に隣接して設けられる。カバー３には端子台４の取り付け部が設けられている。端子台４はカバー３のうち側面部３ａに取り付けられる。なお、カバー３の側面部３ａの内側には、点灯装置５が設けられる。端子台４は側面部３ａを介して点灯装置５と隣接する。 As shown in FIGS. 1 and 2, the terminal block 4 is provided adjacent to the housing 2 and the cover 3. The cover 3 is provided with a mounting portion for the terminal block 4. The terminal block 4 is attached to the side surface portion 3a of the cover 3. A lighting device 5 is provided inside the side surface portion 3a of the cover 3. The terminal block 4 is adjacent to the lighting device 5 via the side surface portion 3a.

端子台４は、外部電源からの電力を点灯装置５に供給する。ここで、外部電源は交流電源または直流電源である。端子台４は電線挿入部４１を有する。電線挿入部４１には電線が挿入される。端子台４は電線により外部電源と接続される。また、端子台４は点灯装置５と電気的に接続される。電線挿入部４１は水平方向を向く。また、電線挿入部４１は側面部３ａに沿った方向を向く。 The terminal block 4 supplies electric power from an external power source to the lighting device 5. Here, the external power supply is an AC power supply or a DC power supply. The terminal block 4 has an electric wire insertion portion 41. An electric wire is inserted into the electric wire insertion portion 41. The terminal block 4 is connected to an external power source by an electric wire. Further, the terminal block 4 is electrically connected to the lighting device 5. The wire insertion portion 41 faces in the horizontal direction. Further, the electric wire insertion portion 41 faces in the direction along the side surface portion 3a.

端子台４は例えば不飽和ポリエステルなどの熱硬化性樹脂から形成される。これに限らず、端子台４は耐熱性能があれば、熱可塑性樹脂から形成されてもよい。 The terminal block 4 is formed of a thermosetting resin such as unsaturated polyester. Not limited to this, the terminal block 4 may be formed of a thermoplastic resin as long as it has heat resistance.

図６は、実施の形態１に係る光源ユニット９０を分解した状態を示す下方斜視図である。図７は、実施の形態１に係る光源ユニット９０を分解した状態を示す上方斜視図である。点灯装置５、光源６、光学制御部７および保持部材９は光源ユニット９０を構成する。保持部材９は、点灯装置５と、光源６と、光学制御部７とを保持する。保持部材９は、例えばソケットである。点灯装置５、光源６および光学制御部７は保持部材９にそれぞれ固定され、一体化された部品となる。 FIG. 6 is a downward perspective view showing a state in which the light source unit 90 according to the first embodiment is disassembled. FIG. 7 is an upward perspective view showing a state in which the light source unit 90 according to the first embodiment is disassembled. The lighting device 5, the light source 6, the optical control unit 7, and the holding member 9 constitute a light source unit 90. The holding member 9 holds the lighting device 5, the light source 6, and the optical control unit 7. The holding member 9 is, for example, a socket. The lighting device 5, the light source 6, and the optical control unit 7 are fixed to the holding member 9, and become integrated parts.

点灯装置５は端子台４から供給される電力により、光源６を点灯させる。点灯装置５はいわゆる直流電源装置である。点灯装置５は、外部電源から電力供給を受け、光源６に対し制御された電力を供給する。光源６に供給される電力の制御方法として、定電流制御、定電力制御、定電圧制御等が用いられる。点灯装置５は樹脂性のケースと、ケースに収納される回路基板を備える。 The lighting device 5 lights the light source 6 by the electric power supplied from the terminal block 4. The lighting device 5 is a so-called DC power supply device. The lighting device 5 receives electric power from an external power source and supplies controlled electric power to the light source 6. As a method of controlling the electric power supplied to the light source 6, constant current control, constant power control, constant voltage control and the like are used. The lighting device 5 includes a resin case and a circuit board housed in the case.

光源６は例えばＬＥＤを備える。ＳＭＤ（Ｓｕｒｆａｃｅ Ｍｏｕｎｔ Ｄｅｖｉｃｅ）タイプのＬＥＤを用いる場合、光源６はＬＥＤおよびＬＥＤを実装する基板から構成される。これに対し、ＣＯＢ（Ｃｈｉｐ Ｏｎ Ｂｏａｒｄ）タイプのＬＥＤを用いる場合、光源６において基板は不要となる。この場合、光源６は、基板の代わりにＬＥＤを保持し点灯装置５と接続する為のソケットを備えても良い。 The light source 6 includes, for example, an LED. When an SMD (Surface Mount Device) type LED is used, the light source 6 is composed of an LED and a substrate on which the LED is mounted. On the other hand, when a COB (Chip On Board) type LED is used, the light source 6 does not require a substrate. In this case, the light source 6 may include a socket for holding the LED and connecting to the lighting device 5 instead of the substrate.

光源６は、点灯装置５と保持部材９との間に設けられる。光源６は下方に向かって光を出射する。光源６が発する光は、保持部材９に設けられた開口を通り、光学制御部７に入射する。 The light source 6 is provided between the lighting device 5 and the holding member 9. The light source 6 emits light downward. The light emitted by the light source 6 passes through the opening provided in the holding member 9 and is incident on the optical control unit 7.

光学制御部７は、光源６の光の出射方向に設けられる。光学制御部７は、保持部材９に対して、光源６および点灯装置５と反対側に設けられる。図１、２に示されるように、光学制御部７は、第１開口２４を塞ぐ。また、光学制御部７は、第１開口２４から外部に臨む様に配設され、第１開口２４から突出する。 The optical control unit 7 is provided in the light emission direction of the light source 6. The optical control unit 7 is provided on the side opposite to the light source 6 and the lighting device 5 with respect to the holding member 9. As shown in FIGS. 1 and 2, the optical control unit 7 closes the first opening 24. Further, the optical control unit 7 is arranged so as to face the outside from the first opening 24, and protrudes from the first opening 24.

光学制御部７は、光源６が出射する光を制御し、第１開口２４から出射する。本実施の形態では、光学制御部７はレンズである。光学制御部７は、光源６の光を目標とする配光特性を満足する様に配光制御する。光学制御部７は例えばガラスで形成される。光学制御部７は、耐熱性能が満足されれば樹脂で形成されてもよい。また、光学制御部７はレンズ以外でも良く、反射板であっても良い。 The optical control unit 7 controls the light emitted by the light source 6 and emits it from the first opening 24. In this embodiment, the optical control unit 7 is a lens. The optical control unit 7 controls the light distribution so as to satisfy the target light distribution characteristics of the light of the light source 6. The optical control unit 7 is formed of, for example, glass. The optical control unit 7 may be made of a resin as long as the heat resistance is satisfied. Further, the optical control unit 7 may be a reflector other than the lens.

筐体２の側壁部２１には保持バネ８を固定する為の取り付け部２１ｃが設けられる。取り付け部２１ｃは対向する２つの平面から構成される。取り付け部２１ｃには、２つの保持バネ８が対向して取り付けられる。保持バネ８は、筐体２の側壁部２１の両側から水平方向に延びる。なお、保持バネ８は筐体２の取り付け部２１ｃに向かって変形する。つまり、保持バネ８は、筐体２に向かって閉じる。 A mounting portion 21c for fixing the holding spring 8 is provided on the side wall portion 21 of the housing 2. The mounting portion 21c is composed of two opposing planes. Two holding springs 8 are attached to the attachment portion 21c so as to face each other. The holding spring 8 extends horizontally from both sides of the side wall portion 21 of the housing 2. The holding spring 8 is deformed toward the mounting portion 21c of the housing 2. That is, the holding spring 8 closes toward the housing 2.

次に、照明器具１の組み立て方法について説明する。まず、光源ユニット９０を組み立てる。このとき、保持部材９に点灯装置５、光源６および光学制御部７を固定し、光源ユニット９０を一体化する。 Next, a method of assembling the lighting fixture 1 will be described. First, the light source unit 90 is assembled. At this time, the lighting device 5, the light source 6, and the optical control unit 7 are fixed to the holding member 9, and the light source unit 90 is integrated.

次に、一体化された光源ユニット９０を、筐体２の第２開口２３から第１開口２４に向かって挿入する。ここで、第２開口２３の幅は、光源ユニット９０の幅より大きい。このため、第２開口２３から筐体２に光源ユニット９０を収納できる。本実施の形態では、光源ユニット９０を筐体２に上方から収納できる。このため、点灯装置などを筐体の下方から取り付ける場合よりも、組立作業を容易にできる。また、本実施の形態では、予め一体化された光源ユニット９０を筐体２に収納する。このため、組立作業をさらに容易にできる。 Next, the integrated light source unit 90 is inserted from the second opening 23 of the housing 2 toward the first opening 24. Here, the width of the second opening 23 is larger than the width of the light source unit 90. Therefore, the light source unit 90 can be housed in the housing 2 from the second opening 23. In the present embodiment, the light source unit 90 can be housed in the housing 2 from above. Therefore, the assembly work can be facilitated as compared with the case where the lighting device or the like is attached from below the housing. Further, in the present embodiment, the light source unit 90 integrated in advance is housed in the housing 2. Therefore, the assembly work can be further facilitated.

また、第１開口２４の幅は光源ユニット９０の幅より小さい。このため、筐体２の下端側で光源ユニット９０を保持できる。従って、光源ユニット９０の落下を防止できる。光源ユニット９０が筐体２に挿入された状態において、筐体２の第１開口２４は光学制御部７で閉塞される。その後、筐体２の上端にカバー３を取り付ける。これにより、第２開口２３が閉塞される。また、カバー３に端子台４を取り付ける。 Further, the width of the first opening 24 is smaller than the width of the light source unit 90. Therefore, the light source unit 90 can be held on the lower end side of the housing 2. Therefore, it is possible to prevent the light source unit 90 from falling. With the light source unit 90 inserted in the housing 2, the first opening 24 of the housing 2 is closed by the optical control unit 7. After that, the cover 3 is attached to the upper end of the housing 2. As a result, the second opening 23 is closed. Further, the terminal block 4 is attached to the cover 3.

保持バネ８は、光源ユニット９０を筐体２に収納する前に、予め筐体２に取り付けておいても良い。また、筐体２に光源ユニット９０を収納した後に、保持バネ８を筐体２に取り付けても良い。 The holding spring 8 may be attached to the housing 2 in advance before the light source unit 90 is housed in the housing 2. Further, the holding spring 8 may be attached to the housing 2 after the light source unit 90 is housed in the housing 2.

次に、照明器具１の被取付部への設置方法について説明する。被取付部は例えば天井である。まず、端子台４の電線挿入部４１に被取付部から引き出された電線を接続する。次に、保持バネ８を筐体２側へすぼめて、照明器具１を被取付部に挿入する。照明器具１が被取付部に差し込まれると、保持バネ８は開いた状態となる。これにより、照明器具１は、被取付部に取り付けられる。 Next, a method of installing the lighting fixture 1 on the attached portion will be described. The attached portion is, for example, a ceiling. First, the electric wire drawn from the attached portion is connected to the electric wire insertion portion 41 of the terminal block 4. Next, the holding spring 8 is squeezed toward the housing 2, and the luminaire 1 is inserted into the attached portion. When the luminaire 1 is inserted into the attached portion, the holding spring 8 is in an open state. As a result, the luminaire 1 is attached to the attached portion.

このように、被取付部への照明器具１の設置作業は、予め組み立てられた照明器具１を被取付部に取り付けることで完了する。従って、施工を容易にできる。また、本実施の形態では、光源ユニット９０を筐体２の上方から挿入するため、筐体２の下端に予め意匠面を設けることができる。このため、筐体２を天井に設置した後に、化粧枠等を筐体２に取り付ける必要がない。従って、施工をさらに容易にできる。 As described above, the work of installing the luminaire 1 on the attached portion is completed by attaching the pre-assembled luminaire 1 to the attached portion. Therefore, construction can be facilitated. Further, in the present embodiment, since the light source unit 90 is inserted from above the housing 2, a design surface can be provided in advance at the lower end of the housing 2. Therefore, it is not necessary to attach the decorative frame or the like to the housing 2 after installing the housing 2 on the ceiling. Therefore, the construction can be made easier.

図８は、実施の形態１に係る端子台４に電線４２が接続された状態を示す図である。電線挿入部４１は筐体２の取り付け部２１ｃに沿った方向を向く。このため、電線４２は、保持バネ８が設けられる方向には引き出されない。これにより、端子台４に電線４２が挿入された状態においても、保持バネ８が電線４２に触れることを防止できる。従って、施工の際に電線４２と保持バネ８が接触することを防止できる。 FIG. 8 is a diagram showing a state in which the electric wire 42 is connected to the terminal block 4 according to the first embodiment. The electric wire insertion portion 41 faces in the direction along the mounting portion 21c of the housing 2. Therefore, the electric wire 42 is not pulled out in the direction in which the holding spring 8 is provided. This makes it possible to prevent the holding spring 8 from touching the electric wire 42 even when the electric wire 42 is inserted into the terminal block 4. Therefore, it is possible to prevent the electric wire 42 and the holding spring 8 from coming into contact with each other during construction.

また、図２の平面図に示されるように、端子台４は筐体２の直上に設けられる。端子台４は筐体２の中心軸に沿った方向から見て、筐体２の内側に収まる。このため、照明器具１を小型化できる。 Further, as shown in the plan view of FIG. 2, the terminal block 4 is provided directly above the housing 2. The terminal block 4 fits inside the housing 2 when viewed from the direction along the central axis of the housing 2. Therefore, the lighting fixture 1 can be miniaturized.

また、図８に示されるように、電線４２は、電線挿入部４１からカバー３の側面部３ａに沿った方向に引き出される。このとき、端子台４の電線４２が引き出される側と反対側には、点灯装置５が設けられない。このため、電線挿入部４１からカバー３の側面部３ａと垂直な方向に電線４２が引き出される場合よりも、筐体２の直上において電線４２が通る空間を広く確保できる。よって、電線４２が照明器具１の横に突き出し難い。従って、照明器具１を被取付部に取り付け易くなり、容易に施工できる。 Further, as shown in FIG. 8, the electric wire 42 is pulled out from the electric wire insertion portion 41 in the direction along the side surface portion 3a of the cover 3. At this time, the lighting device 5 is not provided on the side opposite to the side where the electric wire 42 of the terminal block 4 is drawn out. Therefore, it is possible to secure a wider space for the electric wire 42 to pass directly above the housing 2 than when the electric wire 42 is pulled out from the electric wire insertion portion 41 in the direction perpendicular to the side surface portion 3a of the cover 3. Therefore, it is difficult for the electric wire 42 to protrude to the side of the lighting fixture 1. Therefore, the lighting fixture 1 can be easily attached to the attached portion and can be easily installed.

また、非常用照明器具は建築基準法および関連法令等で性能が規定されている。本実施の形態の照明器具１は、点灯装置５を内蔵し、バッテリー等の予備電源を内蔵しない。このような照明器具において電線の送り、つまり渡り配線が可能な場合、一般に端子台に対し、予め定められた難燃性能が求められる。本実施の形態では、端子台４に熱硬化性樹脂を用いることで、非常用照明器具として規定された難燃性能を満足することができる。 In addition, the performance of emergency lighting equipment is stipulated by the Building Standards Law and related laws and regulations. The lighting fixture 1 of the present embodiment has a built-in lighting device 5 and does not have a built-in backup power source such as a battery. When the electric wire can be fed, that is, crossover wiring is possible in such a lighting fixture, a predetermined flame retardant performance is generally required for the terminal block. In the present embodiment, by using a thermosetting resin for the terminal block 4, the flame retardant performance specified as an emergency lighting fixture can be satisfied.

また、非常用照明器具の天井面より露出する箇所は、一般に難燃材料で形成されることが必要である。本実施の形態における筐体２は、アルミダイキャスト等の金属材料で構成される。このため、非常用照明器具としての要求事項を満足することができる。 Further, the portion exposed from the ceiling surface of the emergency luminaire generally needs to be formed of a flame-retardant material. The housing 2 in the present embodiment is made of a metal material such as aluminum die-cast. Therefore, the requirements as an emergency lighting fixture can be satisfied.

本実施の形態の変形例として、筐体２の側壁部２１には切り欠きが設けられなくても良い。また、筐体２の形状は、図３、４に示されるものに限らない。例えば、筐体２の側壁部２１の断面は、円形、四角形または多角形であっても良い。また、端子台４の電線挿入部４１は、保持バネ８が延びる方向と交差する方向を向いても良い。これにより、電線４２と保持バネ８の干渉を防止できる。 As a modification of the present embodiment, the side wall portion 21 of the housing 2 may not be provided with a notch. Further, the shape of the housing 2 is not limited to that shown in FIGS. 3 and 4. For example, the cross section of the side wall portion 21 of the housing 2 may be circular, quadrangular, or polygonal. Further, the electric wire insertion portion 41 of the terminal block 4 may face in a direction intersecting the direction in which the holding spring 8 extends. This makes it possible to prevent interference between the electric wire 42 and the holding spring 8.

なお、本実施の形態で説明した技術的特徴は適宜に組み合わせて用いてもよい。 The technical features described in this embodiment may be used in combination as appropriate.
