以下、本発明に係る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、本発明に係る実施形態の照明器具１０は、施工面である天井面１１等に取り付けられて下方を照明するものであり、天井面１１に取り付けられる例えば正方形状の器具本体２０を有する。なお、図１においては、器具本体２０の前方（下方）に取り付けられる透光性カバー２６（図３参照）を外した状態である。
また、天井面１１には、照明器具１０を取り付けるための引っ掛けシーリング１２（図３参照）が取り付けられている。 Hereinafter, the lighting fixture of embodiment which concerns on this invention is demonstrated using drawing.
As shown in FIG. 1, the lighting fixture 10 of embodiment which concerns on this invention is attached to the ceiling surface 11 etc. which are construction surfaces, and illuminates the downward direction, for example, a square-shaped fixture attached to the ceiling surface 11 It has a main body 20. In addition, in FIG. 1, the translucent cover 26 (refer FIG. 3) attached to the front (downward) of the instrument main body 20 is removed.
Further, a hooking ceiling 12 (see FIG. 3) for attaching the lighting fixture 10 is attached to the ceiling surface 11.

図２および図３に示すように、器具本体２０は、天井面１１に取り付けられる例えば正方形上の形状のベースプレート２１を有する。ベースプレート２１の中央には、天井面１１の引っ掛けシーリング１２に取り付けることにより照明器具１０を取り付けるための取付金具２５がベースプレート２１を貫通して設けられている。
また、ベースプレート２１の下面２１１には、対向する２端辺２１２、２１３から各々一定幅の区間２１２Ａ、２１３Ａを除いて、端辺２１２、２１３に平行な断面が台形であるＬＥＤユニット取付台２２が取り付けられている。 As shown in FIGS. 2 and 3, the instrument main body 20 includes a base plate 21 having a square shape, for example, attached to the ceiling surface 11. At the center of the base plate 21, an attachment fitting 25 for attaching the lighting fixture 10 by being attached to the hook ceiling 12 of the ceiling surface 11 is provided through the base plate 21.
Further, on the lower surface 211 of the base plate 21, there is an LED unit mounting base 22 having a trapezoidal cross section parallel to the end sides 212 and 213 except for the sections 212A and 213A each having a constant width from the two opposite end sides 212 and 213. It is attached.

取付台２２は、ベースプレート２１と平行な取付面部２３と、取付面部２３の端部とベースプレート２１との間に設けられ、外側に向かってベースプレート２１に近付く方向へ傾斜した傾斜面２４１を有する傾斜面部２４を有する。
なお、取付面部２３は、ベースプレート２１の中央に設けられている取付金具２５との干渉を避けるため、図１に示すように、２分割してもよい。 The mounting base 22 is provided between a mounting surface portion 23 parallel to the base plate 21, and an end surface of the mounting surface portion 23 and the base plate 21, and an inclined surface portion 241 which is inclined outwardly toward the base plate 21. 24.
In addition, in order to avoid interference with the attachment metal fitting 25 provided in the center of the base plate 21, the attachment surface part 23 may be divided into two as shown in FIG.

取付面部２３および傾斜面部２４にはＬＥＤユニット３０が取り付けられている。例えば、取付面部２３には、中央の取付金具２５を挟んで両側に各々３個の取付面部ＬＥＤユニット３１が平行に配設されている。
そして、一対の傾斜面部２４、２４には、各々１個の傾斜面部ＬＥＤユニット３２が傾斜面２４１に配設されており、下方外向きに光を照射する。
さらに、取付面部２３の一対の端面２３１の両外側には、端面２３１とベースプレート２１下面との間に、各々１個の端面部ＬＥＤユニット３３が、傾斜して取り付けられている。この端面部ＬＥＤユニット３３の取付角度は、調整可能とすることができる。 The LED unit 30 is attached to the attachment surface portion 23 and the inclined surface portion 24. For example, on the mounting surface portion 23, three mounting surface portion LED units 31 are arranged in parallel on both sides of the central mounting bracket 25, respectively.
Each of the pair of inclined surface portions 24, 24 is provided with one inclined surface portion LED unit 32 on the inclined surface 241, and irradiates light downward downward.
Furthermore, one end surface LED unit 33 is attached to both outer sides of the pair of end surfaces 231 of the mounting surface portion 23 between the end surface 231 and the lower surface of the base plate 21 so as to be inclined. The attachment angle of the end face LED unit 33 can be adjusted.

なお、ここでは、ＬＥＤユニット取付台２２として、ベースプレート２１の対向する端辺２１２，２１３に沿った断面のみが台形となっている場合を示したが、端辺２１２，２１３に直交する方向にも傾斜面を設けて、全体を下方に尖った四角錐台形状とすることもできる。
従って、端面部ＬＥＤユニット３３が取り付けられている部位も、傾斜面部２４に含むこととする。 In addition, although the case where only the cross section along the opposite end sides 212 and 213 of the base plate 21 is trapezoidal as the LED unit mounting base 22 is shown here, the direction orthogonal to the end sides 212 and 213 is also shown. An inclined surface may be provided to form a truncated pyramid shape that is pointed downward.
Accordingly, the inclined surface portion 24 also includes a portion to which the end surface portion LED unit 33 is attached.

図３に示すように、ベースプレート２１の下面２１１には、前述したＬＥＤユニット３０（取付面部ＬＥＤユニット３１，傾斜面部ＬＥＤユニット３２，端面部ＬＥＤユニット３３の総称である。）を収容する透光性カバー２６が着脱可能に取り付けられる。透光性カバー２６は、下向きに尖る四角錐台形状を呈している。   As shown in FIG. 3, the lower surface 211 of the base plate 21 accommodates the above-described LED unit 30 (a general term for the mounting surface portion LED unit 31, the inclined surface portion LED unit 32, and the end surface portion LED unit 33). The cover 26 is detachably attached. The translucent cover 26 has a quadrangular frustum shape that is pointed downward.

図４に示すように、ＬＥＤユニット３０は全体細長い長方形状をしており、最下層（図４において最上部）に長方形の本体３４を有する。本体３４は、放熱性を向上させるため、アクリルにより形成されている。
これにより、ＬＥＤチップ３５１が発した熱を効率的に放熱できるので、ＬＥＤユニット３０の寿命を大幅に延ばすことができる。 As shown in FIG. 4, the LED unit 30 has a rectangular shape as a whole, and has a rectangular main body 34 in the lowermost layer (the uppermost portion in FIG. 4). The main body 34 is made of acrylic in order to improve heat dissipation.
Thereby, since the heat | fever which LED chip 351 emitted can be thermally radiated efficiently, the lifetime of LED unit 30 can be extended significantly.

本体３４の上（図４において下）には、複数のＬＥＤチップ３５１を実装したＬＥＤ基板３５が取り付けられる。少なくとも傾斜面部２４に配設されている傾斜面部ＬＥＤユニット３２，端面部ＬＥＤユニット３３においては、ＬＥＤチップ３５１は、ＬＥＤ基板３５上に１列の直線上に配列されている。
本体３４の上（図４において下）には、ＬＥＤチップ３５１およびＬＥＤ基板３５を覆う難燃性の樹脂で形成された透光性のカバー３６が配設される。 An LED substrate 35 on which a plurality of LED chips 351 are mounted is attached on the main body 34 (lower in FIG. 4). At least in the inclined surface portion LED unit 32 and the end surface portion LED unit 33 disposed on the inclined surface portion 24, the LED chips 351 are arranged on a straight line on the LED substrate 35.
A translucent cover 36 made of a flame-retardant resin that covers the LED chip 351 and the LED substrate 35 is disposed on the main body 34 (lower in FIG. 4).

そして、ＬＥＤ基板３５およびカバー３６を本体３４に取り付けるために、全体枠状のアンダーカバー３７が本体３４に取り付けられる。アンダーカバー３７は、ＡＢＳで形成されており、ねじ等の締結手段を用いずに本体３４に取り付けられて、アンダーカバー３７と本体３４との間にＬＥＤ基板３５およびカバー３６を挟持する。従って、ＬＥＤユニット３０を下方から見たときには、ＬＥＤユニット３０を組み立てているねじ等の締結手段は見えない。
なお、上述したようなＬＥＤユニット３０は、傾斜面部２４に限らず、取付面部２３にも同じＬＥＤユニット３０を用いることができる。 Then, in order to attach the LED substrate 35 and the cover 36 to the main body 34, an overall frame-shaped under cover 37 is attached to the main body 34. The under cover 37 is formed of ABS, is attached to the main body 34 without using fastening means such as screws, and sandwiches the LED substrate 35 and the cover 36 between the under cover 37 and the main body 34. Therefore, when the LED unit 30 is viewed from below, the fastening means such as screws that assemble the LED unit 30 cannot be seen.
In addition, the LED unit 30 as described above can be used not only for the inclined surface portion 24 but also for the attachment surface portion 23.

図５には、照明器具による部屋Ｒの床面Ｆに対する照明範囲（図中ハッチング部分）が示されている。
図５（Ａ）に示すように、取付面部２３の外側に傾斜面部２４の傾斜面部ＬＥＤユニット３２（端面部ＬＥＤユニット３３）を設けた照明器具１０によれば、部屋Ｒの床面Ｆの隅や壁面Ｗまで照明光が照射される。なお、図示はしないが、取付面部２３の取付面部ＬＥＤユニット３１の長手方向に直交する傾斜面部２４には、端面部ＬＥＤユニット３３が設けられている。
一方、図５（Ｂ）に示すように、傾斜面部２４を設けず、全て取付面部２３に取付面部ＬＥＤユニット３１を取り付けた場合には、部屋Ｒの床面Ｆの隅や壁面Ｗまで照明光が照射されていない。
これにより、傾斜面部２４に設けた傾斜面部ＬＥＤユニット３２，端面部ＬＥＤユニット３３により部屋Ｒの隅々まで照明できることが分かる。 FIG. 5 shows an illumination range (hatched portion in the figure) for the floor surface F of the room R by the lighting fixture.
As shown in FIG. 5A, according to the luminaire 10 in which the inclined surface portion LED unit 32 (end surface portion LED unit 33) of the inclined surface portion 24 is provided outside the mounting surface portion 23, the corner of the floor surface F of the room R is shown. Illumination light is irradiated up to the wall surface W. Although not shown, an end surface LED unit 33 is provided on the inclined surface 24 perpendicular to the longitudinal direction of the mounting surface LED unit 31 of the mounting surface 23.
On the other hand, as shown in FIG. 5B, when the inclined surface portion 24 is not provided and the mounting surface portion LED unit 31 is attached to the mounting surface portion 23, the illumination light reaches the corners and the wall surfaces W of the floor surface F of the room R. Is not irradiated.
Thereby, it turns out that it can illuminate to every corner of the room R by the inclined surface part LED unit 32 provided in the inclined surface part 24, and the end surface part LED unit 33.

図６（Ａ）ないし（Ｃ）には、傾斜面部２４の傾斜面部ＬＥＤユニット３２，端面部ＬＥＤユニット３３（以後、端面部ＬＥＤユニット３３について説明する。）の傾斜角度の調整による照明範囲の調整（調光）を示している。
図６（Ａ）に示すように、端面部ＬＥＤユニット３３の傾斜角度を調整することにより、床面Ｆと壁面Ｗを連続して同時に照明することができる。
また、端面部ＬＥＤユニット３３の指向性が強いので、図６（Ｂ）に示すように、端面部ＬＥＤユニット３３の傾斜角度を水平側（上側）へ調整することにより、家具Ｔ等の障害物を避けて、壁面Ｗのみ照明することができる。
なお、傾斜面部２４の端面部ＬＥＤユニット３３を設けていない場合には、図６（Ｃ）に示すように、床面Ｆのみの照明となる。 6A to 6C, adjustment of the illumination range by adjusting the inclination angle of the inclined surface portion LED unit 32 and the end surface portion LED unit 33 of the inclined surface portion 24 (hereinafter, the end surface LED unit 33 will be described). (Dimming) is shown.
As shown to FIG. 6 (A), the floor surface F and the wall surface W can be illuminated simultaneously by adjusting the inclination-angle of the end surface part LED unit 33 continuously.
Moreover, since the directivity of the end surface LED unit 33 is strong, as shown in FIG. 6B, the obstacle such as the furniture T is adjusted by adjusting the inclination angle of the end surface LED unit 33 to the horizontal side (upper side). In this way, only the wall surface W can be illuminated.
In addition, when the end surface part LED unit 33 of the inclined surface part 24 is not provided, as shown in FIG.6 (C), it becomes illumination of only the floor surface F. FIG.
