Description

本発明は、電源部から電力の供給を受けて光源を点灯させ、光源の発する熱を放熱フィンによって放熱する照明器具に関するものである。   The present invention relates to a luminaire that receives power supplied from a power supply unit to light a light source, and dissipates heat generated by the light source by a radiation fin.

従来より、天井等の取り付け部位に取り付ける照明器具で、光源が発する熱を放熱フィンにより放熱する照明器具が知られている（例えば、特許文献１参照）。
図９に示すように、特許文献１に記載の照明器具１００は、例えば天井に設けられた取付孔に挿入して取り付けるダウンライトである。 2. Description of the Related Art Conventionally, there is known a lighting fixture that is attached to a mounting site such as a ceiling and radiates heat generated by a light source with a heat radiating fin (see, for example, Patent Document 1).
As shown in FIG. 9, the lighting fixture 100 described in Patent Literature 1 is a downlight that is attached by being inserted into an attachment hole provided in a ceiling, for example.

照明器具１００は、内部に光源であるＬＥＤ（図示省略）を収容する器具本体（以後、「灯具」という。）１０１を有する。また、灯具１０１の照明方向と反対側（図９において上側）には、ＬＥＤが発した熱を放熱するために、薄板状の放熱フィン１０２が多数設けられている。また、放熱フィン１０２の上部には、灯具１０１の投影範囲内に収容され、かつ、放熱フィン１０２の外側に突出可能なアーム部１０４が設けられている。アーム部１０４には、ＬＥＤに点灯電力を供給する電源部１０３が取り付けられている。   The lighting fixture 100 includes a fixture main body (hereinafter referred to as “lamp”) 101 that houses an LED (not shown) as a light source. In addition, on the side opposite to the illumination direction of the lamp 101 (upper side in FIG. 9), a large number of thin plate-like heat radiation fins 102 are provided in order to radiate the heat generated by the LEDs. In addition, an arm portion 104 that is accommodated within the projection range of the lamp 101 and can protrude to the outside of the radiation fin 102 is provided on the upper portion of the radiation fin 102. A power supply unit 103 that supplies lighting power to the LEDs is attached to the arm unit 104.

従って、アーム部１０４を折りたたんだ状態では、電源部１０３は灯具１０１の投影範囲内に収まるので、輸送梱包する際や施工する際に便利である。
また、アーム部１０４を放熱フィン１０２から外側に移動させることにより（図９に示す状態）、ＬＥＤと電源部１０３とが離れるので、ＬＥＤの熱が電源装置へ伝わりにくいという利点がある。 Therefore, when the arm unit 104 is folded, the power source unit 103 is within the projection range of the lamp 101, which is convenient when packaging and transporting.
Further, by moving the arm portion 104 to the outside from the radiation fin 102 (the state shown in FIG. 9), the LED and the power source portion 103 are separated from each other, so that there is an advantage that the heat of the LED is not easily transmitted to the power source device.

しかしながら、灯具と電線等で電気的に接続された電源部が、灯具と別々に被取付部に取り付けられる場合がある。
このような場合には、灯具と電源部とを別々に搬送したり、取り付けたりすることができない。このため、電源部を天井裏等に配線されている商用電源に接続する際に、灯具と電源部とを保持しながら、脚立の上等の高所で作業を行わねばならず、作業性が悪いという問題があった。 However, the power supply unit electrically connected to the lamp by an electric wire or the like may be attached to the mounted part separately from the lamp.
In such a case, the lamp and the power supply unit cannot be transported or attached separately. For this reason, when connecting the power supply unit to a commercial power supply wired on the ceiling or the like, the work must be performed at a high place such as on a stepladder while holding the lamp and the power supply unit. There was a problem of being bad.

本発明は、従来の問題を解決するためになされたもので、灯具と電線等で電気的に接続された電源部を、灯具と別々で被取付部に取り付ける際に、作業性を改善できる照明器具を提供することを目的とする。   The present invention was made in order to solve the conventional problems, and lighting that can improve workability when a power supply unit electrically connected with a lamp and an electric wire or the like is attached to a mounted part separately from the lamp. The purpose is to provide equipment.

本発明の照明器具は、光源を収容し所定方向へ光を照射する灯具と、前記灯具に一体的に設けられて前記光源の発する熱を放熱する放熱フィンと、前記灯具とは別個に設けられて前記光源を点灯させる箱形の電源部と、を有し、前記放熱フィンに、前記電源部を保持可能な電源部保持部を設けたものである。   The lighting fixture of the present invention is provided separately from a lamp that houses a light source and emits light in a predetermined direction, a radiation fin that is provided integrally with the lamp and radiates heat generated by the light source, and the lamp. A box-shaped power supply unit that turns on the light source, and a power supply unit holding unit capable of holding the power supply unit is provided on the heat radiating fin.

また、本発明の照明器具は、前記電源部保持部が、前記電源部の外形に対応して設けられた電源部用凹部であるものである。   Moreover, the lighting fixture of this invention is a recessed part for power supply parts in which the said power supply part holding | maintenance part was provided corresponding to the external shape of the said power supply part.

また、本発明の照明器具は、前記放熱フィンにおける前記電源部用凹部と反対側に、作業者の腕の形状に対応して設けられた保持用凹部を有するものである。   Moreover, the lighting fixture of this invention has the recessed part for holding provided in the opposite side to the said recessed part for power supply parts in the said radiation fin corresponding to the shape of an operator's arm.

本発明では、光源を有する灯具の放熱フィンに電源部保持部を設けたので、灯具と電源部とが別個に設置される場合で、灯具と電源部の両方を保持して取付作業をしなければならない場合に、電源部を電源部用凹部で保持した状態で取付作業ができ、作業性が改善されるという効果を有する照明器具を提供できる。   In the present invention, since the power supply unit holding part is provided on the radiating fin of the lamp having the light source, it is necessary to hold both the lamp and the power supply part when the lamp and the power supply part are separately installed. In the case where it is necessary, it is possible to provide a luminaire having an effect that the mounting work can be performed in a state where the power supply unit is held by the recess for the power supply unit and workability is improved.

（第１実施形態）
以下、本発明に係る第１実施形態の照明器具について、図面を用いて説明する。
図１に示すように、本発明に係る第１実施形態の照明器具１０は、被取付部である天井１１に形成された取付孔（図示省略）に埋設して下方を照明するダウンライトとすることができる。 (First embodiment)
Hereinafter, the lighting fixture of 1st Embodiment which concerns on this invention is demonstrated using drawing.
As shown in FIG. 1, the lighting fixture 10 of 1st Embodiment which concerns on this invention is set as the downlight which embeds in the attachment hole (illustration omitted) formed in the ceiling 11 which is a to-be-attached part, and illuminates the downward direction. be able to.

照明器具１０は、光源であるＬＥＤ２１（図４参照）を収容して所定方向へ照明光を照射する灯具２０を有する。灯具２０は、円柱形状の枠体２３に、回動可能（図１中矢印Ａ参照）に支持されており、照明方向の調整が可能となっている。枠体２３の下端（図１において下端）には、鍔部材２４が取り付けられ、枠体２３の側面には複数個（ここでは、例えば３個設けられているが図１においては２個のみ図示する。）の取付バネ２５が放射状に外側へ張り出して設けられている。
従って、灯具２０は、天井１１の下面に鍔部材２４を当接させ、取付バネ２５が天井１１の上面（天井裏）を下方へ押圧することにより、鍔部材２４と取付バネ２５とで天井１１を挟んで取り付けられる。 The luminaire 10 includes a lamp 20 that houses an LED 21 (see FIG. 4) that is a light source and emits illumination light in a predetermined direction. The lamp 20 is supported by a columnar frame 23 so as to be rotatable (see arrow A in FIG. 1), and the illumination direction can be adjusted. A collar member 24 is attached to the lower end (lower end in FIG. 1) of the frame body 23, and a plurality (here, for example, three are provided on the side surface of the frame body 23, but only two are shown in FIG. The mounting spring 25 is provided to project radially outward.
Therefore, the lamp 20 causes the ceiling member 24 to contact the lower surface of the ceiling 11 and the mounting spring 25 presses the upper surface (ceiling back) of the ceiling 11 downward. It can be attached with

灯具２０には、ＬＥＤ２１を点灯させる電力を供給する電源部３０が、電線３１で接続されており、天井裏（天井１１の上面側）に、灯具２０とは別々に取り付けられる。
図２に示すように、電源部３０は、矩形箱形の筐体３２を有し、例えば長手方向両端に天井１１に固定するための取付部３３を有する。また、天井裏に配線されている商用電源の電源線１２に接続するための接続端子台３４を有しており、電源線１２の先端を差し込みことにより電気的に接続されるようになっている。 The lamp 20 is connected to a power supply unit 30 for supplying power for turning on the LED 21 with an electric wire 31, and is attached to the back of the ceiling (upper surface side of the ceiling 11) separately from the lamp 20.
As illustrated in FIG. 2, the power supply unit 30 includes a rectangular box-shaped housing 32, and includes mounting portions 33 for fixing to the ceiling 11 at both ends in the longitudinal direction, for example. Moreover, it has the connection terminal block 34 for connecting with the power wire 12 of the commercial power source wired by the ceiling back, and is electrically connected by inserting the front-end | tip of the power wire 12. FIG. .

図１に示すように、灯具２０には、ＬＥＤ２１が発する熱を放熱する複数枚の薄板状の放熱フィン２２が一体的に設けられている。放熱フィン２２は、灯具２０の回動方向と反対側に設けられている幅広の第１放熱フィン２２１と、回動方向側に設けられている幅狭な第２放熱フィン２２２を有する。
なお、第１放熱フィン２２１と、第２放熱フィン２２２を総称する場合には、放熱フィン２２と記すこととする。 As shown in FIG. 1, the lamp 20 is integrally provided with a plurality of thin plate-like heat radiation fins 22 that radiate heat generated by the LEDs 21. The radiation fin 22 has a wide first radiation fin 221 provided on the side opposite to the rotation direction of the lamp 20, and a narrow second radiation fin 222 provided on the rotation direction side.
Note that the first radiating fin 221 and the second radiating fin 222 are collectively referred to as the radiating fin 22.

第２放熱フィン２２２の高さ方向中央部には、電源部３０を保持可能な電源部保持部として電源部用凹部２６が設けられている。電源部用凹部２６は、電源部３０の外形に対応して設ける。
すなわち、電源部用凹部２６は、電源部３０の筐体３２を嵌め込んで保持できる大きさおよび形状を有する。 At the center in the height direction of the second radiating fin 222, a power supply unit recess 26 is provided as a power supply unit holding unit capable of holding the power supply unit 30. The power supply recess 26 is provided corresponding to the outer shape of the power supply 30.
That is, the power supply recess 26 has a size and shape that allows the housing 32 of the power supply 30 to be fitted and held.

次に、照明器具１０を天井１１に取り付ける作業について説明する。
照明器具１０の灯具２０は、天井１１の取付孔（図示省略）に埋め込まれて、鍔部材２４と取付バネ２５との間に天井１１を挟持して取り付けられる。
一方、電源部３０は、天井裏に配線されている商用電源の電源線１２に接続されて、灯具２０とは別個に天井裏に取り付けられる。このため、灯具２０を天井１１に取り付ける前に、電源部３０に電源線１２を接続する。 Next, an operation for attaching the lighting fixture 10 to the ceiling 11 will be described.
The lamp 20 of the lighting fixture 10 is embedded in an attachment hole (not shown) of the ceiling 11 and is attached with the ceiling 11 sandwiched between the flange member 24 and the attachment spring 25.
On the other hand, the power supply unit 30 is connected to the commercial power supply line 12 wired on the back of the ceiling, and is attached to the back of the ceiling separately from the lamp 20. For this reason, the power supply line 12 is connected to the power supply unit 30 before the lamp 20 is attached to the ceiling 11.

電源部３０は電線３１によって灯具２０と接続されているため、電源部３０および灯具２０の両方を保持して取付を行わねばならない。
このため、図３に示すように、灯具２０の第１放熱フィン２２１の先端が略水平になるように灯具２０を横にして、電源部用凹部２６が上向きに略水平になるようにする。そして、電源部３０を電源部用凹部２６に上方から嵌め込んで（図３矢印Ａ参照）、仮保持する。
次いで、図４に示すように、作業者は、灯具２０を下方から手で支持し（図４中矢印Ａ参照）、灯具２０に保持された電源部３０の接続端子台３４に電源線１２の先端を差し込んで接続する。 Since the power supply unit 30 is connected to the lamp 20 by the electric wire 31, it must be attached while holding both the power supply unit 30 and the lamp 20.
Therefore, as shown in FIG. 3, the lamp 20 is laid sideways so that the front ends of the first heat dissipating fins 221 of the lamp 20 are substantially horizontal, and the power supply recess 26 is substantially horizontal upward. Then, the power supply 30 is fitted into the power supply recess 26 from above (see arrow A in FIG. 3) and temporarily held.
Next, as shown in FIG. 4, the operator manually supports the lamp 20 from below (see arrow A in FIG. 4), and connects the power line 12 to the connection terminal block 34 of the power supply unit 30 held by the lamp 20. Insert the tip and connect.

その後、電源部３０を灯具から外して取付孔（図示省略）から天井裏に入れて載置あるいは取り付けを行った後に、灯具２０を取付孔（図示省略）に取り付ける。
なお、第２放熱フィン２２２は、灯具２０の回動方向にあるため、誤って電源部３０を電源部用凹部２６に保持したまま灯具２０を天井１１に取り付けた場合には、灯具２０を回動させることにより誤作業を容易に発見することができる。 Thereafter, the power supply unit 30 is removed from the lamp and placed or attached to the ceiling through an attachment hole (not shown), and then the lamp 20 is attached to the attachment hole (not shown).
Since the second radiating fin 222 is in the rotation direction of the lamp 20, if the lamp 20 is mistakenly attached to the ceiling 11 with the power supply 30 held in the power supply recess 26, the lamp 20 is turned. It is possible to easily find an erroneous operation by moving it.

以上、説明した本発明に係る第１実施形態の照明器具１０によれば、灯具２０に収容されているＬＥＤ２１は、電線３１で灯具２０と接続された電源部３０から電力の供給を受けて点灯し、所定方向を照明する。このときＬＥＤ２１が発する熱は、灯具２０に一体的に設けられている放熱フィン２２によって放熱される。
電源部３０は、灯具２０とは別個に天井１１に取り付けられるが、予め、電線３１で灯具２０に接続されている場合には、別々に搬送や取り付けを行うことができない。このため、灯具２０と電源部３０の両方を保持して、取付作業をしなければならない。このとき、灯具２０の放熱フィン２２に、電源部３０を保持可能な電源部用凹部２６を設けたので、電源部３０を電源部用凹部２６で保持した状態で取付作業ができ、作業性が改善される。 As mentioned above, according to the lighting fixture 10 of 1st Embodiment which concerns on this invention demonstrated, LED21 accommodated in the lamp 20 receives supply of electric power from the power supply part 30 connected with the lamp 20 with the electric wire 31, and it lights. Then, a predetermined direction is illuminated. At this time, the heat generated by the LED 21 is radiated by the radiation fins 22 provided integrally with the lamp 20.
The power supply unit 30 is attached to the ceiling 11 separately from the lamp 20. However, when the power supply unit 30 is connected to the lamp 20 in advance by an electric wire 31, it cannot be transported or attached separately. For this reason, it is necessary to hold both the lamp 20 and the power supply unit 30 and perform the installation work. At this time, since the power supply section recess 26 capable of holding the power supply section 30 is provided in the heat radiating fin 22 of the lamp 20, the mounting work can be performed with the power supply section 30 held by the power supply section recess 26. Improved.

また、放熱フィン２２に、電源部保持部として電源部３０の外形に対応した電源部用凹部２６を設けたので、電源部３０を電源部用凹部２６に嵌めて保持した状態で取付作業ができ、作業性が改善される。   Further, since the power supply unit recess 26 corresponding to the outer shape of the power supply unit 30 is provided in the heat radiation fin 22 as the power supply unit holding unit, the mounting operation can be performed with the power supply unit 30 fitted and held in the power supply unit recess 26. , Workability is improved.

なお、前述した照明器具１０においては、第２放熱フィン２２２に電源部用凹部２６を設けた場合を例示したが、逆の場合も可能である。
すなわち、第１放熱フィン２２１に電源部用凹部２６を設けることも可能である。 In addition, in the lighting fixture 10 mentioned above, although the case where the recessed part 26 for power supply parts was provided in the 2nd radiation fin 222 was illustrated, the reverse case is also possible.
That is, it is possible to provide the power supply section recess 26 in the first heat radiation fin 221.

（第２実施形態）
次に、本発明に係る第２実施形態の照明器具について説明する。
なお、前述した第１実施形態の照明器具１０と共通する部位には同じ符号を付して、重複する説明を省略することとする。

As shown in FIG. 5, in the luminaire 10B of the second embodiment, in the radiating fin 22B, the operator's arm is placed on the first radiating fin 221B on the side opposite to the second radiating fin 222 provided with the power supply recess 26. A holding recess 27 was provided corresponding to the shape of M (see FIG. 6).

従って、図６に示すように、電源部３０の接続端子台３４に電源線１２を接続する際に、保持した電源部３０が上に位置するように灯具２０Ｂを配置すると、保持用凹部２７は下向きに位置する。このため、保持用凹部２７を作業者の腕Ｍに合わせることにより、電源部３０を保持した灯具２０Ｂを支持することができる。
なお、電源部３０および灯具２０の天井１１への取付作業は、前述した第１実施形態の場合と同様である。 Therefore, as shown in FIG. 6, when the lamp 20B is arranged so that the held power supply unit 30 is positioned when the power supply line 12 is connected to the connection terminal block 34 of the power supply unit 30, the holding recess 27 is Located downwards. For this reason, the lamp 20B holding the power supply unit 30 can be supported by aligning the holding recess 27 with the arm M of the operator.
The work of attaching the power supply unit 30 and the lamp 20 to the ceiling 11 is the same as in the case of the first embodiment described above.

以上、説明した本発明に係る第２実施形態の照明器具１０Ｂによれば、放熱フィン２２Ｂにおける電源部用凹部２６と反対側には、作業者の腕Ｍの形状に対応した保持用凹部２７が設けられている。
このため、作業者は、作業時に腕Ｍを保持用凹部２７に嵌めて、腕Ｍに灯具２０あるいは灯具２０および電源部３０を載せた状態で保持することができるので、両手で電源部３０の結線作業等を行うことができ、作業性を改善できる。 As described above, according to the lighting fixture 10B of the second embodiment of the present invention described above, the holding recess 27 corresponding to the shape of the operator's arm M is provided on the side opposite to the power supply recess 26 in the radiating fin 22B. Is provided.
For this reason, the operator can hold the lamp 20 or the lamp 20 and the power supply unit 30 on the arm M by fitting the arm M into the holding recess 27 at the time of work. Wiring work can be performed and workability can be improved.

また、前述した照明器具１０Ｂにおいては、第２放熱フィン２２２に電源部用凹部２６を設け、第１放熱フィン２２１Ｂに保持用凹部２７を設けた場合を例示したが、逆の場合も可能である。
すなわち、第１放熱フィン２２１Ｂに電源部用凹部２６を設け、第２放熱フィン２２２に保持用凹部２７を設けることも可能である。 Further, in the lighting fixture 10B described above, the case where the second heat radiation fins 222 are provided with the power source recesses 26 and the first heat radiation fins 221B are provided with the holding recesses 27 is illustrated, but the reverse case is also possible. .
In other words, it is possible to provide the first heat radiating fin 221 </ b> B with the power supply recess 26 and the second heat radiating fin 222 with the holding recess 27.

（第３実施形態）
次に、本発明に係る第３実施形態の照明器具について説明する。
なお、前述した第１実施形態の照明器具１０および第２実施形態の照明器具１０Ｂと共通する部位には同じ符号を付して、重複する説明を省略することとする。 (Third embodiment)
Next, the lighting fixture of 3rd Embodiment which concerns on this invention is demonstrated.
In addition, suppose that the same code | symbol is attached | subjected to the site | part which is common in the lighting fixture 10 of 1st Embodiment mentioned above, and the lighting fixture 10B of 2nd Embodiment, and the overlapping description is abbreviate | omitted.

図７に示すように、第３実施形態の照明器具１０Ｃでは、電源部保持部として、放熱フィン２２Ｃの頂部に電源部３０を保持可能な保持板２８を設けた。保持板２８は、放熱フィン２２Ｃの一部として一体的に設けることもできる。
従って、第１実施形態の照明器具１０および第２実施形態の照明器具１０Ｂの第２放熱フィン２２２に設けた電源部用凹部２６および第２実施形態の照明器具１０Ｂの第１放熱フィン２２１Ｂに設けた保持用凹部２７は、設けられていない。 As shown in FIG. 7, in the lighting fixture 10 </ b> C of the third embodiment, a holding plate 28 that can hold the power supply unit 30 is provided on the top of the heat radiation fin 22 </ b> C as a power supply holding unit.
