When folded, the light-emitting panel 3 is disposed so as to face the light-emitting surface 2.

矩形板状本体３５は、矩形板状基体１２の横方向Ｈの長さと同等の長さを有している。矩形板状本体３５の横方向Ｈに伸びた上縁３８は、ヒンジ１４を介して矩形板状基体１２の下縁５にＲ１及びＲ２方向に回動自在に連結されている。矩形板状本体３５の横方向Ｈに伸びた下縁（自由端縁）３９には、本例ではバンドア４１が横方向Ｈに伸びる軸を介してｒ１及びｒ２方向に回動自在となるように連結されている。   The rectangular plate-shaped main body 35 has a length equivalent to the length in the lateral direction H of the rectangular plate-shaped substrate 12.

It is connected.

尚、矩形板状本体３５は、本例では、バンドア４１が連結されているために、発光パネル３の縦方向Ｖの幅の半分よりも短い幅をもって構成されているが、例えばバンドア４１が連結されていない場合には、発光パネル３又は発光パネル３の発光面２の縦方向Ｖの幅の半分と同等の幅をもって構成されていてもよい。   In this example, since the band plate 41 is connected to the rectangular plate-shaped main body 35, the rectangular plate body 35 has a width shorter than half of the width in the vertical direction V of the light emitting panel 3. For example, the band plate 41 is connected. If not, the light emitting panel 3 or the light emitting surface 2 of the light emitting panel 3 may be configured to have a width equivalent to half the width in the vertical direction V.

The rotatable plate 7 is rotated in the R2 direction so that the light emitting surface 2 is exposed while the light emitting surface 2 is exposed, so that the unfolded state shown in FIGS. By deploying in this way, the LED lighting device 1 can ensure a wide light emitting surface.

本例のＬＥＤ照明装置１によれば、複数の発光ダイオード（図示せず）が配列されてなる発光面２を有した矩形板状の発光パネル３と、発光パネル３の上縁４及び下縁５の夫々に横方向Ｈに伸びた軸の周りでＲ１及びＲ２方向に回動自在となるように連結されている互いに同形状の一対の回動自在板６及び７とを具備しており、回動自在板６及び７の夫々は、Ｒ１方向の回動において発光面２を覆いながら発光パネル３と重ね合わされる一方、Ｒ２方向の回動において発光面２を露呈させながら展開できるように構成されているために、発光パネル３の発光面２が広く形成されていても一対の回動自在板６及び７をＲ１方向に回動させて発光パネル３と重ね合わせるように折り畳むことで搬送容易にし得る一方、回動自在板６及び７をＲ２方向に回動させることで発光パネル３の発光面２を露呈させて速やかに装置を設置することができ、しかも、前記折り畳み時に発光パネル３の発光面２を回動自在板６及び７によって覆うことができるので搬送時に発光面２に損傷が生じる虞をなくし得る。   According to the LED illumination device 1 of this example, a rectangular plate-like light emitting panel 3 having a light emitting surface 2 in which a plurality of light emitting diodes (not shown) are arranged, and an upper edge 4 and a lower edge of the light emitting panel 3. A pair of rotatable plates 6 and 7 having the same shape and connected so as to be rotatable in directions R1 and R2 around an axis extending in the horizontal direction H, respectively. Each of the rotatable plates 6 and 7 is configured to be able to be unfolded while exposing the light emitting surface 2 in the rotation in the R2 direction while overlapping the light emitting panel 3 while covering the light emitting surface 2 in the rotation in the R1 direction. Therefore, even if the light emitting surface 2 of the light emitting panel 3 is widely formed, the pair of rotatable plates 6 and 7 are rotated in the R1 direction and folded so as to be overlapped with the light emitting panel 3 for easy conveyance. On the other hand, the rotatable plates 6 and 7 can be placed in the R2 direction. The device can be quickly installed by exposing the light emitting surface 2 of the light emitting panel 3 by rotating the light emitting panel 3, and the light emitting surface 2 of the light emitting panel 3 is covered with the rotatable plates 6 and 7 during the folding. Therefore, the possibility that the light emitting surface 2 is damaged during transportation can be eliminated.

ＬＥＤ照明装置１によれば、回動自在板６及び７のうちの少なくとも一方、本例では双方の回動自在板６及び７の夫々の一方の面２６及び３６であって発光パネル３に対面し得る前記面２６及び３６には、複数の発光ダイオードが配列されてなる発光面２７及び３７が形成されているために、装置の大型化を生じさせずに発光面を更に広く形成することができ、しかも、発光パネル３に対する回動自在板６及び７の回動角度を適宜調節することによって照明範囲や被射体に対する光量を好適に調整し得、加えて、回動自在板６及び７の横方向Ｈに伸びる自由端縁２９及び３９には、横方向Ｈに伸びる軸を介して回動自在となるようにバンドア３１及び４１が夫々連結されているために、当該バンドア３１及び４１によっても照明範囲等を適宜調整し得る。   According to the LED lighting device 1, at least one of the rotatable plates 6 and 7, in this example, one of the surfaces 26 and 36 of both the rotatable plates 6 and 7, facing the light emitting panel 3. Since the light-emitting surfaces 27 and 37 in which a plurality of light-emitting diodes are arranged are formed on the surfaces 26 and 36 that can be formed, the light-emitting surface can be formed wider without causing an increase in the size of the device. In addition, by appropriately adjusting the rotation angle of the rotatable plates 6 and 7 with respect to the light emitting panel 3, the illumination range and the amount of light with respect to the subject can be suitably adjusted, and in addition, the rotatable plates 6 and 7 can be adjusted. Since the band ends 31 and 41 are connected to the free end edges 29 and 39 extending in the horizontal direction H through the shaft extending in the horizontal direction H, respectively, As well as lighting range etc. It can be an integer.

尚、ＬＥＤ照明装置１では、回動自在板６及び７に代えて、例えば図５に示すようにバンドアから構成された回動自在板４６及び４７を具備していてもよい。斯かる回動自在板４６及び４７の夫々は、発光パネル３の発光面２の縦方向Ｖの幅の半分と同等の幅を有していてもよい。   Note that the LED illumination device 1 may include, instead of the rotatable plates 6 and 7, for example, rotatable plates 46 and 47 made of a band as shown in FIG. Each of such rotatable plates 46 and 47 may have a width equivalent to half of the width in the vertical direction V of the light emitting surface 2 of the light emitting panel 3.
