Description

本発明は、照明器具に関する。 The present invention relates to a luminaire.

近年、照明器具は省エネルギー化に鑑み、LED（Light Emitting Diode）を光源部に備えた照明器具が使用される傾向にある。 In recent years, in view of energy saving, lighting fixtures equipped with an LED (Light Emitting Diode) as a light source have tended to be used.

従来、倉庫や体育館といった高天井等に設置される照明器具は、傾斜した天井等に取り付けられる場合であっても照射面を下面に向けられるように角度調整機構が設けられている。 Conventionally, a lighting fixture installed on a high ceiling such as a warehouse or a gymnasium is provided with an angle adjusting mechanism so that the irradiation surface can be directed to the lower surface even when the lighting fixture is attached to a sloping ceiling or the like.

このような高天井等に設置される照明器具は、機械やボールなどの衝突による衝撃や地震による振動に耐える耐久性が求められていた。 Lighting fixtures installed on such high ceilings are required to have durability to withstand shocks caused by collisions of machines and balls and vibrations caused by earthquakes.

The tubular portion 74 is formed with an opening on the back surface side having a diameter concentric with a substantially circular shape formed by arranging a plurality of light emitting elements 61 of the substrate 60 and having a diameter larger than a substantially circular shape formed by arranging a plurality of light emitting elements 61. Further, the diameter of the front side opening of the tubular portion 74 is formed to be substantially the same as the diameter of the back side opening of the radial portion 71.

カバー部8は、図８に示すように、プレート1の前面とともに反射板部7の前面および側面を覆うように形成される樹脂製などの透光性を有する部材である。カバー部8の前面から見た場合の外縁は、プレート1の外縁と略同一に形成される。 As shown in FIG. 8, the cover portion 8 is a transparent member made of resin or the like, which is formed so as to cover the front surface and the side surface of the reflector portion 7 together with the front surface of the plate 1. The outer edge when viewed from the front surface of the cover portion 8 is formed to be substantially the same as the outer edge of the plate 1.

以下、本発明の実施形態における効果について説明する。 Hereinafter, the effects of the embodiments of the present invention will be described.

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 part 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. 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 are less likely to be deformed and the durability is 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 communication hole which are the support shafts for rotation in the arm portion 2 and the mounting plate portion 3 are provided. The screw portion 9 that communicates 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 communication hole 311 which are the support shafts for 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 communicating with the fixing hole 221 and the first communication hole 311 which are the support shafts of the rotation in 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に固定されているため干渉しない。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, so that they do not interfere with each other. 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 mounted 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 dimension of the radiator 5 and the light source unit 6 in the relevant direction, it is possible to reduce the size of the power supply unit 4 and the size and weight of the appliance 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 for rotation in the arm portion 2 and the mounting plate portion 3 is sufficiently short. The effect of suppressing the shaking of the front end 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 hole 221 and the elongated hole 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 portion 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 in the conventional case where the fixing hole 221 is 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, so that 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. This can be expected to reduce the number of members and the weight of the equipment.
