　カバー３７は、ＬＥＤ３５を覆うカバーであり、グローブ、セード等の名称で呼ばれる部材である。カバー３７は、例えば、ポリカーボネート樹脂のような光拡散性を有する透光性の樹脂材料によって中空でかつ、開口を有する略直方体状に形成される。カバー３７は、開口側が本体前面３１Ｂに向けられた状態で、本体３１に固定され、開口内にはＬＥＤ３５が実装された基板３４の前面を含む、本体３１の前面３１Ｂの全体を包むように前面側（床面側）から覆う。カバー３７は、ＬＥＤ３５を保護するとともにＬＥＤ３５からの光を均等に拡散する。 The cover 37 is a cover that covers the LED 35, and is a member called a glove, a shade, or the like. The cover 37 is made of, for example, a translucent resin material having light diffusion properties such as polycarbonate resin, and is hollow and formed in a substantially rectangular parallelepiped shape having an opening. The cover 37 is fixed to the main body 31 with the opening side facing the main body front surface 31B, and the front side so as to cover the entire front surface 31B of the main body 31 including the front surface of the board 34 on which the LEDs 35 are mounted in the opening. Cover from (floor side). The cover 37 protects the LEDs 35 and evenly diffuses the light from the LEDs 35 .
　図２Ａの○印Ｂ内の構造を、図２Ｂに示す。実施形態における本体３１は、略長方形状の平板からなり、本体３１の長手方向の両端部には突出部３２が形成されている。突出部３２は、前面方向にＬ字形に垂直に折れた側面部３２Ａと、その先端に天井９側に円弧を描くように湾曲した先端部３２Ｂから構成されている。 The structure inside circle B in FIG. 2A is shown in FIG. 2B. The main body 31 in the embodiment is made of a substantially rectangular flat plate, and protrusions 32 are formed at both ends in the longitudinal direction of the main body 31 . The protruding portion 32 is composed of a side portion 32A that is bent vertically in an L shape in the front direction, and a tip portion 32B that is curved to draw an arc toward the ceiling 9 side at the tip of the side portion 32A.
　カバー３７は、曲面状に形成された前面部３７Ａと、略垂直な壁部３７Ｂと、略水平をなす水平面部３７Ｃと、略垂直な縁部３７Ｄから構成されている。本体３１の側面部３２Ａとカバー３７の縁部３７Ｄはほぼ同形状をなしている。本体３１の長手方向の両端部に形成されたＪ字状の突出部３２の側面部３２Ａと先端部３２Ｂによって形成された空間に、カバー３７のＪ字状の縁部３７Ｄが本体３１の長手方向から挿通されることによって組み合わされる。その後、光源３の断面形状と同形状に形成された断面形状を有するサイドキャップ８０を、光源３の両端部に嵌めることによって、カバー３７は、動かないように本体３１に固定される。 The cover 37 is composed of a curved front surface portion 37A, a substantially vertical wall portion 37B, a substantially horizontal horizontal surface portion 37C, and a substantially vertical edge portion 37D. The side surface portion 32A of the main body 31 and the edge portion 37D of the cover 37 have substantially the same shape. The J-shaped edge 37D of the cover 37 extends in the longitudinal direction of the main body 31 in the space formed by the side surface 32A and the tip 32B of the J-shaped projection 32 formed at both ends of the main body 31 in the longitudinal direction. are combined by being inserted from the Thereafter, side caps 80 having the same cross-sectional shape as the light source 3 are fitted to both ends of the light source 3 to fix the cover 37 to the main body 31 so as not to move.
　本体３１とカバー３７とは、本体３１の突出部３２とカバー３７の縁部３７Ｄとの係合によって組み立てられるので、従来例のような複数の留具７６を用いて、本体３１とかばー３７とを接合する煩雑な作業が不要であり、組み立て作業の効率化を図ることができる。さらに、留具７６を使用しないため、本体３１とカバー３７とを強固に連結することが可能である。
　また、実施形態では、本体３１とカバー３７との間に、間隙を有するので、ＬＥＤ３５が実装された基板３４や電源回路３６等の発熱により発生する本体３１やカバー３７等の部品の熱膨張は、上記間隙で吸収されるため、熱膨張によるきしみ音等の音鳴りを防止することができる。 The main body 31 and the cover 37 are assembled by engaging the protruding portion 32 of the main body 31 and the edge portion 37D of the cover 37, so that the main body 31 and the cover 37 can be assembled using a plurality of fasteners 76 as in the conventional example. This eliminates the need for a troublesome work of joining the parts together, thus making it possible to improve the efficiency of the assembly work. Furthermore, since the fastener 76 is not used, the main body 31 and the cover 37 can be firmly connected.
In addition, in the embodiment, since there is a gap between the main body 31 and the cover 37, thermal expansion of the parts such as the main body 31 and the cover 37 caused by heat generated by the board 34 on which the LED 35 is mounted and the power supply circuit 36 is prevented. Since it is absorbed by the gap, it is possible to prevent noise such as squeaking noise due to thermal expansion.
　さらに、カバー３７の表面に複数の凸部３８を形成してもよい。図２Ｂに示すように、実施形態では、凸部３８は、取付部品２の底部３０と当接する水平面部３７Ｃに２カ所、本体３１の側面部３２Ａと当接するＪ字形の縁部３７Ｄの壁面にそれぞれ２カ所ずつ設けられている。凸部３８は、上記本体３１とカバー３７との間に生じる間隙に加え、照明器具１の使用時において、カバー３７の表面と本体３１の側面部３２Ａの表面との一定の距離を保つことで、本体３１等の温度上昇時に、各部材の熱膨張等により発生するきしみ音などの音鳴りを防止する役割を果たす。 Furthermore, a plurality of protrusions 38 may be formed on the surface of the cover 37 . As shown in FIG. 2B, in the embodiment, the protrusions 38 are provided at two locations on the horizontal surface portion 37C that contacts the bottom portion 30 of the mounting component 2, and on the wall surface of the J-shaped edge portion 37D that contacts the side surface portion 32A of the main body 31. There are two of each. In addition to the gap generated between the main body 31 and the cover 37, the convex portion 38 maintains a constant distance between the surface of the cover 37 and the surface of the side surface portion 32A of the main body 31 when the lighting device 1 is in use. , and prevents noise such as squeaking noise generated due to thermal expansion of each member when the temperature of the main body 31 and the like rises.
　カバー３７の表面に設けられた凸部３８は、半円筒形の突起がカバー３７の長手方向に沿って、縁部３７Ｄと平行に４カ所（４条）形成されたものであるが、凸部３８を半球状の部材で形成し、点状列としてもよい。また、凸部３８の配置数も４カ所に限らず、必要に応じて適宜数を配置すればよい。 The convex portion 38 provided on the surface of the cover 37 is formed by four semi-cylindrical projections (four streaks) along the longitudinal direction of the cover 37 and parallel to the edge portion 37D. 38 may be formed of a hemispherical member and arranged in a dotted row. Moreover, the number of protrusions 38 to be arranged is not limited to four, and an appropriate number may be arranged as necessary.
　また、図２Ｂに示すように、本体３１の先端に位置する先端部３２Ｂとカバー３７の壁部３７Ｂとは、点線で示す断面楕円形状の空間αを隔てて配置されている。空間αは、幅ａ、高さｂ及び高さｃによって囲まれる空間である。光源３から照射された光は、カバー３７の内部を通って空間αに到達する。到達した光は、カバー３７の略垂直な壁部３７Ｂを通って、カバー３７の外部に放出され、壁部３７Ｂを明るく光らせる。本体３１とカバー３７との間に、空間αを有することで、ＬＥＤ３５から照射された光は周辺に均等に拡散され、カバー３７の隅部に暗部が生じることがない。本体３１とカバー３７とは、本体３１の突出部３２とカバー３７の壁部３７Ｂとの間に、光源３から出射された光が差し込む空間を有するように配置されている。
　長さａは、本体３１の先端部３２Ｂとカバー３７の間の距離であり、長さｂは取付部品２の底部３０と本体３１のJ字状の突出部３２の先端部３２Ｂとカバー３７の水平面部３７Ｃの凸部３８とが接する水平面との距離であり、長さｃは、カバー３７の垂直な壁部３７Ｂと取付部品２の底部３０との間の距離である。
　長さａは、１．０～１０．０ｍｍ、好ましくは２．０～５．０ｍｍである。長さｂは、３．０～２０．０ｍｍ、好ましくは４．０～１２．０ｍｍである。また、長さｃは、５．０～２０．０ｍｍ、好ましくは、８．０～１２．０ｍｍである。 Further, as shown in FIG. 2B, the distal end portion 32B located at the distal end of the main body 31 and the wall portion 37B of the cover 37 are arranged with a space α having an elliptical cross section indicated by a dotted line. Space α is a space enclosed by width a, height b and height c. Light emitted from the light source 3 reaches the space α through the inside of the cover 37 . The light that has reached the cover 37 passes through the substantially vertical wall portion 37B and is emitted to the outside of the cover 37, brightening the wall portion 37B. Since the space α is provided between the main body 31 and the cover 37 , the light emitted from the LED 35 is diffused evenly around the periphery, and no dark portion is generated in the corner of the cover 37 . The main body 31 and the cover 37 are arranged so that there is a space between the projecting portion 32 of the main body 31 and the wall portion 37B of the cover 37 into which the light emitted from the light source 3 is inserted.
The length a is the distance between the tip 32B of the main body 31 and the cover 37, and the length b is the distance between the bottom 30 of the attachment part 2, the tip 32B of the J-shaped projection 32 of the main body 31, and the cover 37. The length c is the distance between the vertical wall portion 37B of the cover 37 and the bottom portion 30 of the mounting part 2. It is the distance between the horizontal surface portion 37C and the horizontal surface with which the convex portion 38 is in contact.
The length a is 1.0-10.0 mm, preferably 2.0-5.0 mm. The length b is 3.0-20.0 mm, preferably 4.0-12.0 mm. Also, the length c is 5.0 to 20.0 mm, preferably 8.0 to 12.0 mm.
　光源取付部２１の外壁面には、従来例と同様、外側に向けた半球状の緩衝部材２２が、複数設けられており、緩衝部材２２が天井９と取付部品２に設けられた垂直面３０Ｂに当接することで、光源３のガタつきが防止されるとともに確実に位置固定される。 A plurality of hemispherical cushioning members 22 directed outward are provided on the outer wall surface of the light source mounting portion 21 as in the conventional example. , the light source 3 is prevented from rattling and is securely fixed in position.
　なお、この発明は、上記実施形態に限定されず、上記実施形態に対して種々の変形および応用が可能である。 It should be noted that the present invention is not limited to the above embodiments, and various modifications and applications are possible with respect to the above embodiments.
