Description

本発明の実施形態は、照明器具に関する。 Embodiments of the present invention relate to luminaires.

従来、例えば施設等の天井が高い空間の照明に用いられる高天井用の照明器具がある。この照明器具では、発光素子を有する発光モジュールが用いられ、この発光モジュールが放熱器の下面に取り付けられている。放熱器の上面には発光素子が発生する熱を放熱するための複数の放熱フィンが突設されている。放熱器はこの放熱器の上方に配設される本体シャーシに支持され、この本体シャーシ上に電源部が配設されている。本体シャーシには天井等に設置するためのアームが連結されている。 Conventionally, for example, there are lighting fixtures for high ceilings used for lighting spaces with high ceilings such as facilities. In this luminaire, a light emitting module having a light emitting element is used, and this light emitting module is attached to the lower surface of a radiator. A plurality of heat radiating fins for dissipating the heat generated by the light emitting element are provided on the upper surface of the radiator. The radiator is supported by a main body chassis arranged above the radiator, and a power supply unit is arranged on the main body chassis. An arm for installing on the ceiling or the like is connected to the main body chassis.

この照明器具の構成では、部品点数が多く、構造が複雑になっているとともに、重くなっている。照明器具が重い場合、照明器具自体の重量によりアームが引っ張られて変形する虞がある。アームが変形した場合、天井面との接触面積が小さくなり、照明器具の揺れを抑える効果が薄くなってしまうため、照明器具の揺れを安定して抑えることができる構造が求められていた。 In the configuration of this luminaire, the number of parts is large, the structure is complicated, and the structure is heavy. If the luminaire is heavy, the weight of the luminaire itself may pull the arm and deform it. When the arm is deformed, the contact area with the ceiling surface becomes small, and the effect of suppressing the shaking of the luminaire becomes weak. Therefore, a structure capable of stably suppressing the shaking of the luminaire has been required.

この照明器具の揺れを抑えるために、板厚を厚くして変形しにくいアームを用いることが検討されている。しかしこのアームを用いた場合、板厚の分だけコストや照明器具重量が増加してしまうという問題点があった。 In order to suppress the shaking of this luminaire, it is being studied to use an arm with a thick plate that is not easily deformed. However, when this arm is used, there is a problem that the cost and the weight of the luminaire increase by the thickness of the plate.

次に本実施形態の照明器具を、被設置場所として例えば天井に、取付部材としてボルトを用いて取り付ける際の動きについて説明をする。なお、このような照明器具を天井に取り付ける場合、照明器具と天井との接触面が小さい場合、照明器具は天井に対しての押さえが利かなくなることで設置安定性が弱くなり、振動で揺れやすくなる虞があるため、照明器具と天井との接触面が重要となる。 Next, the movement when the lighting fixture of the present embodiment is mounted on the ceiling as a place to be installed by using a bolt as a mounting member will be described. When such a luminaire is attached to the ceiling, if the contact surface between the luminaire and the ceiling is small, the luminaire cannot be pressed against the ceiling, which weakens the installation stability and shakes due to vibration. The contact surface between the luminaire and the ceiling is important because it may be easy.

照明器具を天井に取り付ける際は、アーム部2が天井と対向するように照明器具を配設する。この状態ではアーム部2の設置部21は天井と略平行となっている。この状態から、ボルトを取付孔23と天井に配設したボルト受に挿入して照明器具を天井方向に締め上げていくと、図１２（ａ）に示すように、アーム部2の突起部25が天井に接触する。 When mounting the luminaire on the ceiling, the luminaire is arranged so that the arm portion 2 faces the ceiling. In this state, the installation portion 21 of the arm portion 2 is substantially parallel to the ceiling. From this state, when the bolt is inserted into the mounting hole 23 and the bolt receiver arranged on the ceiling and the luminaire is tightened toward the ceiling, as shown in FIG. 12A, the protrusion 25 of the arm portion 2 Touches the ceiling.

この状態からさらにボルトを締め上げると、ボルトが挿入されている取付孔23の近傍が天井方向に持ち上がるように力が加わる。その結果、図１２（ｂ）に示すように、設置部21が変形して設置部21の中央領域が天井と接触する。つまり、アーム部2の設置部21の中央部であり、本実施形態においては、取付孔23の間の領域が富士形状に変形し、富士形状の突出した部分が天井と接触する。この状態でも突起部25は天井と接しており、最初に天井と接触してから、ボルトを締め上げて取り付けが完了するまで、突起部25は天井と接触し続ける。この突出部分と突起部25が天井と接触した状態で照明器具が取り付けられる。 When the bolt is further tightened from this state, a force is applied so that the vicinity of the mounting hole 23 into which the bolt is inserted is lifted toward the ceiling. As a result, as shown in FIG. 12B, the installation portion 21 is deformed and the central region of the installation portion 21 comes into contact with the ceiling. That is, it is the central portion of the installation portion 21 of the arm portion 2, and in the present embodiment, the region between the mounting holes 23 is deformed into a Fuji shape, and the protruding portion of the Fuji shape comes into contact with the ceiling. Even in this state, the protrusion 25 is in contact with the ceiling, and the protrusion 25 continues to be in contact with the ceiling from the first contact with the ceiling until the bolts are tightened and the installation is completed. The luminaire is attached with the protrusion and the protrusion 25 in contact with the ceiling.

この照明器具の取り付けにおいて、ボルトを締め上げる力は照明器具の重量と同等以上のトルクであることが望ましい。照明器具設置後にアーム部2にかかる応力以上の力でアーム部2を締め上げて変形させることで、照明器具設置後のアーム部2の変形を抑制することができる。 In mounting the luminaire, it is desirable that the force for tightening the bolt is a torque equal to or greater than the weight of the luminaire. By tightening and deforming the arm portion 2 with a force equal to or greater than the stress applied to the arm portion 2 after the lighting fixture is installed, the deformation of the arm portion 2 after the lighting fixture is installed can be suppressed.

従来の照明器具は、アーム部2に突起部25が存在せず、アーム部2の設置部21のほぼ全体が天井と接触するように取り付けられていた。しかし、この取り付け方法では、天井に取り付けられている取付孔23近辺、もしくは取付孔23の間の領域は強固に取り付いているが、取付孔23より外側の領域、つまり、設置部21において取付孔23より垂直部22側の領域は
アーム部2で保持している照明器具全体の重みによってアーム部2が重力方向に引っ張られ変形する虞がある。その結果、アーム部2の設置部21全体が富士形状に変形し、アーム部2と天井が接触する面積が小さくなり設置安定性が弱くなり、照明器具の揺れが生じてしまうという問題点があった。 In the conventional luminaire, the arm portion 2 does not have a protrusion 25, and almost the entire installation portion 21 of the arm portion 2 is attached so as to be in contact with the ceiling. However, in this mounting method, the area near the mounting hole 23 mounted on the ceiling or the area between the mounting holes 23 is firmly attached, but the area outside the mounting hole 23, that is, the mounting hole in the mounting portion 21 In the region on the side of the vertical portion 22 from 23, the arm portion 2 may be pulled and deformed in the direction of gravity due to the weight of the entire luminaire held by the arm portion 2. As a result, there is a problem that the entire installation portion 21 of the arm portion 2 is deformed into a Fuji shape, the area where the arm portion 2 and the ceiling contact is reduced, the installation stability is weakened, and the lighting equipment is shaken. It was.

本実施形態においては、予めアーム部2が変形する量に相当する突起部25を設置部21に設け、取り付け時に器具重量以上のトルクをアーム部2にかけて取り付けることで、器具重量でアーム部2が変形することを抑制できる。また、従来の取り付け方法と比べて、突起部25の分だけ天井との接触面積を大きくすることができ、設置安定性を高め、照明器具の揺れを防止することが可能となる。 In the present embodiment, a protrusion 25 corresponding to the amount of deformation of the arm portion 2 is provided in the installation portion 21 in advance, and a torque equal to or greater than the weight of the instrument is applied to the arm portion 2 at the time of attachment, so that the arm portion 2 is attached by the weight of the instrument. Deformation can be suppressed. Further, as compared with the conventional mounting method, the contact area with the ceiling can be increased by the amount of the protrusion 25, the installation stability can be improved, and the luminaire can be prevented from shaking.

また本実施形態においては、突起部25は、設置部21から垂直部22に移り変わる部分である曲げ部の近傍に設けられており、取付孔23から離間した場所に設けられており。先述の通り、取付孔23の近傍は強固に天井に取り付けられているため、変形するリスクは低い。この取付孔23から離間するほど変形するリスクが大きく、またその変形の変位量も大きくなることから、この部分の突起部25を設けることでさらに設置安定性を高めることができる。また、取付孔23から離間した場所に突起部25を設けることで、アーム部2と天井が接している領域を、例えば、中央と端部といった形で分散させることができ、より設置安定性を高める効果が期待できる。 Further, in the present embodiment, the protrusion 25 is provided near the bent portion which is a portion where the installation portion 21 shifts to the vertical portion 22, and is provided at a place separated from the mounting hole 23. As described above, since the vicinity of the mounting hole 23 is firmly mounted on the ceiling, the risk of deformation is low. The greater the distance from the mounting hole 23, the greater the risk of deformation, and the greater the amount of displacement of the deformation. Therefore, the installation stability can be further improved by providing the protrusion 25 in this portion. Further, by providing the protrusion 25 at a place separated from the mounting hole 23, the area where the arm portion 2 and the ceiling are in contact can be dispersed in the form of, for example, the center and the end, and the installation stability can be further improved. The effect of enhancing can be expected.

この設置安定性を高めるためには、例えば、アーム部2の板厚を大きくして照明器具の重みでは変形しないような構造とする施策が行われている。アーム部2の板厚を大きくした場合は、設置安定性が高くはなるが、板厚を増した分だけコストが増加して、照明器具全体の重量が増加してしまう虞がある。本実施形態のように、必要部分に突起部25を設ける構造とすることで、コストや重量の増加を抑えつつ照明器具の設置安定性を高めることが可能となる。 In order to improve the installation stability, for example, measures have been taken to increase the plate thickness of the arm portion 2 so that the structure is not deformed by the weight of the luminaire. If the plate thickness of the arm portion 2 is increased, the installation stability is improved, but the cost increases by the amount of the increased plate thickness, and the weight of the entire luminaire may increase. By providing the protrusion 25 at the required portion as in the present embodiment, it is possible to improve the installation stability of the luminaire while suppressing the increase in cost and weight.

また、本実施形態においては、設置部21の長手方向に直交する方向に一端側及び他端側にそれぞれ少なくとも2つ以上の突起25が設けられている。具体的には、照明器具の回動方向であるアーム部2の長孔222の方向に沿って２点の突起部25が配設されている。照明器具は回動方向に揺れやすくなる虞があり、仮に１点の突起物25で保持した場合は、回動方向に揺れた場合、片方向もしくは両方向の抑えが効かないため、そのまま照明器具が揺れてしまう。本実施形態のように、回動方向に沿って２点の突起部25で天井に接触することで、回動方向のどちらの揺れに対しても抑えが効き、設置後の安定の向上が期待できる。このように重量を持つ回動する照明器具については、回動方向の揺れを考慮して、２点の突起部25を設けることが重要となる。 Further, in the present embodiment, at least two or more protrusions 25 are provided on one end side and the other end side in the direction orthogonal to the longitudinal direction of the installation portion 21. Specifically, two protrusions 25 are arranged along the direction of the elongated hole 222 of the arm portion 2, which is the rotation direction of the luminaire. The luminaire may easily sway in the rotation direction, and if it is held by a single protrusion 25, if it sways in the rotation direction, the luminaire cannot be suppressed in one or both directions. It shakes. As in the present embodiment, by contacting the ceiling with the two protrusions 25 along the rotation direction, it is effective to suppress the shaking in either direction of rotation, and it is expected that the stability after installation will be improved. it can. For a rotating luminaire having such a weight, it is important to provide two protrusions 25 in consideration of shaking in the rotation direction.

また同様に、本実施形態においては、アーム部2の長手方向に対しても２点の突起部25を配設しており、アーム部2の長手方向の揺れに対しても抑えることが可能となる。 Similarly, in the present embodiment, the two protrusions 25 are arranged also in the longitudinal direction of the arm portion 2, and it is possible to suppress the shaking of the arm portion 2 in the longitudinal direction. Become.

なお、上記で説明した取り付ける際の動きは上記に示した方法に限定されるものではない。例えば、アーム部2の突起部25を天井に接触させてからボルトを用いて取り付けるといった動きで取り付けられても良い。 The movement at the time of mounting described above is not limited to the method shown above. For example, the protrusion 25 of the arm portion 2 may be attached by bringing it into contact with the ceiling and then attaching it using a bolt.

また、突起部25はアーム部2に設けられなくても良い。被設置場所側である天井に突起部25に該当する突起を設けても良いし、被設置場所である天井とアーム部2の間の空間に突起部25に該当する部材を挟みこんで天井に取り付けられても良い。
他の効果を以下に示す。 Further, the protrusion 25 does not have to be provided on the arm 2. A protrusion corresponding to the protrusion 25 may be provided on the ceiling on the side to be installed, or a member corresponding to the protrusion 25 may be sandwiched in the space between the ceiling and the arm 2 to be installed on the ceiling. It may be attached.
Other effects are shown below.

従来の照明器具においては、放熱器5の背面から離間して、電源部4を設置するためのフレームが設けられていた。そこで照明器具の軽量化のため、フレームを除いた構造として、アーム部2の垂直部22を放熱器5側面付近に取り付ける構造が考えられていた。しかし、図１０に示すように、アーム部2に電源部4および放熱器5を固定すると、アーム部2を回動させた際に電源部4と放熱器5が干渉する可能性があった。 In the conventional lighting equipment, a frame for installing the power supply unit 4 is provided at a distance from the back surface of the radiator 5. Therefore, in order to reduce the weight of the luminaire, a structure in which the vertical portion 22 of the arm portion 2 is attached near the side surface of the radiator 5 has been considered as a structure excluding the frame. However, as shown in FIG. 10, if the power supply unit 4 and the radiator 5 are fixed to the arm unit 2, there is a possibility that the power supply unit 4 and the radiator 5 may interfere with each other when the arm unit 2 is rotated.

電源部4と放熱器5との干渉を防ぐためには、アーム部2および取付板部3における回動の支軸である固定孔221および第一連通孔311を連通するネジ部9から被設置場所と接する設置部21までの長さを十分長くする構造や、回動方向を器具の一方向のみにする構造が考えられるが、前者では照明器具の高さが高くなってしまい、後者では放熱器を電源部4と干渉しない他方側へ配設するため、器具のバランスが低下する。 In order to prevent interference between the power supply unit 4 and the radiator 5, it is installed from the screw portion 9 that communicates the fixing hole 221 and the first series through hole 311 that are the support shafts for rotation in the arm portion 2 and the mounting plate portion 3. A structure in which the length to the installation portion 21 in contact with the place is sufficiently long, or a structure in which the rotation direction is limited to only one direction of the fixture can be considered, but the height of the lighting fixture becomes high in the former, and heat dissipation in the latter. Since the device is arranged on the other side that does not interfere with the power supply unit 4, the balance of the device is reduced.

本発明の実施形態における照明器具は、一対の取付板部3に対して、アーム部2の垂直部22が一対の第一縦板部31を外側から押さえるように取り付けられるとともに、電源部4の一対の短手方向側面が一対の第一縦板部31を内側から支持するように取り付けられる。また、一対の取付板部3に対して、一対の延出部511が一対の第二縦板部33を内側から押さえるように取り付けられる。このように、外側および内側からバランスよく部材が取り付けられることによって、変形しにくく耐久性を高める効果が期待できる。 In the luminaire according to the embodiment of the present invention, the vertical portion 22 of the arm portion 2 is attached to the pair of mounting plate portions 3 so as to press the pair of first vertical plate portions 31 from the outside, and the power supply unit 4 A pair of lateral sides in the lateral direction are attached so as to support a pair of first vertical plate portions 31 from the inside. Further, the pair of extending portions 511 are attached to the pair of mounting plate portions 3 so as to press the pair of second vertical plate portions 33 from the inside. By attaching the members from the outside and the inside in a well-balanced manner in this way, it is expected that the members will not be easily deformed and the durability will be enhanced.

本発明の実施形態における照明器具は、電源部4が一対の取付板部3間に取り付けられ、アーム部2および取付板部3における回動の支軸である固定孔221および第一連通孔311を連通するネジ部9が、電源部4よりも背面側に位置する。また、設置部21からアーム部2および取付板部3における回動の支軸である固定孔221および第一連通孔311に連通されるネジ部9までの距離は、アーム部2および取付板部3における回動の支軸である固定孔221および第一連通孔311に連通されるネジ部9から取付板部3の前面側端部までの距離よりも短くなる。 In the luminaire according to the embodiment of the present invention, the power supply unit 4 is mounted between the pair of mounting plate portions 3, and the fixing hole 221 and the first series of through holes which are the support shafts for rotation in the arm portion 2 and the mounting plate portion 3 The screw portion 9 that communicates with the 311 is located on the back side of the power supply portion 4. Further, the distance from the installation portion 21 to the screw portion 9 communicating with the fixing hole 221 and the first series through hole 311 which are the support shafts of rotation in the arm portion 2 and the mounting plate portion 3 is the arm portion 2 and the mounting plate. It is shorter than the distance from the screw portion 9 communicated with the fixing hole 221 and the first series through hole 311 which are the support shafts of the rotation of the portion 3 to the front end portion of the mounting plate portion 3.

これにより、アーム部2を回動させた場合に電源部4および放熱器5は互いに離間して取付板部3に固定されており、また電源部4および放熱器5は同時に回動するため干渉しない。このため、垂直部22および取付板部3を合わせた長さも最低限の長さでよく、照明器具の小型軽量化が可能となる。 As a result, when the arm portion 2 is rotated, the power supply portion 4 and the radiator 5 are separated from each other and fixed to the mounting plate portion 3, and the power supply portion 4 and the radiator 5 rotate at the same time, thereby interfering with each other. do not do. Therefore, the total length of the vertical portion 22 and the mounting plate portion 3 may be the minimum length, and the luminaire can be made smaller and lighter.

また、一対の取付板部3は、電源部4が取り付けられる第一縦板部31および器具外縁部に設けられる第二縦板部33を傾斜部32を介し一体として形成されることにより、電源部4の長手方向寸法を放熱器5および光源部6の当該方向寸法よりも短く設計できるため、光源部6の発光面積を減らすことなく電源部4の小型化及び器具の小型軽量化が可能となる。 Further, the pair of mounting plate portions 3 is formed by integrally forming the first vertical plate portion 31 to which the power supply portion 4 is attached and the second vertical plate portion 33 provided on the outer edge of the appliance via the inclined portion 32, thereby supplying power. Since the longitudinal dimension of the unit 4 can be designed to be shorter than the directional dimension of the radiator 5 and the light source unit 6, it is possible to reduce the size of the power supply unit 4 and the size and weight of the fixture without reducing the light emitting area of the light source unit 6. Become.

また、被設置部から、アーム部2および取付板部3における回動の支軸である固定孔221および第一連通孔311を連通するネジ部9までの長さが十分に短いことにより、天井等の被設置部から受ける振動による垂直部22の前面側端部の揺れが抑制できるという効果が期待できる。また、一対の垂直部22と一対の取付板部3の接続部分である固定孔221および長孔222が背面側の被設置部付近に設けられることにより、ボールなどの障害物が衝突しにくくなるため、照明器具の耐久性が高まることが期待できる。 Further, the length from the installed portion to the screw portion 9 that communicates the fixing hole 221 and the first series through hole 311 which are the support shafts of rotation in the arm portion 2 and the mounting plate portion 3 is sufficiently short. It is expected that the effect of suppressing the shaking of the front end portion of the vertical portion 22 due to the vibration received from the installed portion such as the ceiling can be expected. Further, since the fixing holes 221 and the elongated holes 222, which are the connecting portions of the pair of vertical portions 22 and the pair of mounting plate portions 3, are provided near the mounted portions on the back side, obstacles such as balls are less likely to collide. Therefore, it can be expected that the durability of the lighting equipment will be improved.

アーム部2の可動部の支点である固定孔221が天井付近にあり、照明器具前面からの距離が長いことにより、本発明の実施形態の使用者が照明器具前面付近を持って光源部6の照射角度を調整する場合、固定孔221が放熱器5の側面付近にあった従来と比べ、少ない力で回動できるため、施工性が高まる効果が期待できる。 Since the fixing hole 221 which is the fulcrum of the movable portion of the arm portion 2 is near the ceiling and the distance from the front surface of the luminaire is long, the user of the embodiment of the present invention holds the vicinity of the front surface of the luminaire and holds the light source portion 6. When adjusting the irradiation angle, the fixing hole 221 can be rotated with less force than the conventional one near the side surface of the radiator 5, so that the effect of improving workability can be expected.

また、電源部4の長手方向寸法と一対の第一縦板部31間の距離が略同一に形成されることにより、電源部4によって第一縦板部31が曲がり難くなり強度が高まるという効果が期待できる。 Further, since the longitudinal dimension of the power supply unit 4 and the distance between the pair of the first vertical plate portions 31 are formed to be substantially the same, the power supply unit 4 makes it difficult for the first vertical plate portion 31 to bend and increases the strength. Can be expected.

本発明の実施形態における照明器具は、光源部6における基板60が、方向確認部63を有する。これにより、器具の組立において基板60をプレート1に取り付ける方向を直感的に判断可能なため、照明器具の組立効率が向上する効果が期待できる。 In the luminaire according to the embodiment of the present invention, the substrate 60 in the light source unit 6 has a direction confirmation unit 63. As a result, the direction in which the substrate 60 is attached to the plate 1 can be intuitively determined when assembling the fixture, and the effect of improving the assembly efficiency of the lighting fixture can be expected.

本発明の実施形態における照明器具は、基板60の発光素子61が設けられない部分に孔部64が複数形成される。また、基板60の外縁部である辺の中央付近には、括れ部62が設けられる。これにより、部材の削減および器具の重量削減が期待できる。 In the luminaire according to the embodiment of the present invention, a plurality of holes 64 are formed in a portion of the substrate 60 where the light emitting element 61 is not provided. Further, a constricted portion 62 is provided near the center of the side which is the outer edge portion of the substrate 60. As a result, reduction of members and weight of equipment can be expected.
