The length dimension of the pedestal 21 is also set to such a size that a gap is provided between the slope 213 of the pedestal 21 and the end face 45 of the transmission cover 40.

図1および図3(A)に示すように、光源部30は、器具本体20の台座21の上面212に取り付けられる板状の基板31を有する。
矩形板状の基板31の実装面311には、外周部に円環状のバンク312が設けられており、バンク312の内側にLEDチップ(発光素子)32が実装されている。
バンク312の内側は、LEDチップ32を覆う封入樹脂33によって封止されており、いわゆるCOB(Chip on Board)タイプとなっている。基板31には、点灯電力を供給する一対のリード線34が接続されている。
なお、基板31の実装面311には、各リード線34に所定以上の電流が流れるのを遮断して、LEDチップ32を保護する保護素子35が設けられている。
As shown in FIGS. 1 and 3A, the light source unit 30 includes a plate-like substrate 31 that is attached to the upper surface 212 of the base 21 of the instrument body 20.
An annular bank 312 is provided on the outer peripheral portion of the mounting surface 311 of the rectangular plate-shaped substrate 31, and an LED chip (light emitting element) 32 is mounted inside the bank 312.
The inside of the bank 312 is sealed with an encapsulating resin 33 that covers the LED chip 32 and is of a so-called COB (Chip on Board) type. A pair of lead wires 34 for supplying lighting power is connected to the substrate 31.
The mounting surface 311 of the substrate 31 is provided with a protective element 35 that protects the LED chip 32 by blocking the flow of a predetermined current or more through each lead wire 34.

LEDチップ32の上側には、透光性のレンズ部材36が設けられている。
レンズ部材36は、全体略円盤形状をしており、中央には、基板31のLEDチップ32の照射方向を覆うレンズ部(レンズ)361が、上方に突出して設けられている。レンズ部361は、表面が楕円形状のレンズである。
なお、レンズ部材36は、楕円形状のレンズ部361の長軸方向が、器具本体20および透過カバー40の長尺方向と一致するように配置される。
A translucent lens member 36 is provided on the upper side of the LED chip 32.
The lens member 36 has a substantially disk shape as a whole, and a lens portion (lens) 361 covering the irradiation direction of the LED chip 32 of the substrate 31 is provided in the center so as to protrude upward. The lens unit 361 is a lens having an elliptical surface.
The lens member 36 is disposed so that the major axis direction of the elliptical lens portion 361 coincides with the longitudinal direction of the instrument main body 20 and the transmission cover 40.

レンズ部361は、頭頂部364の肉厚が、頭頂部364以外の周囲部365の肉厚よりも小さくなっている。
これにより、図3(B)に示すように、配光形状Rが楕円の長軸方向(図3(B)において左右方向)に長くなる。
レンズ部材36の外周縁部には、鍔部362が設けられている。鍔部362には、等間隔で複数個(ここでは、4個)のねじ孔363が設けられている。
In the lens part 361, the thickness of the top part 364 is smaller than the thickness of the surrounding part 365 other than the top part 364.
Accordingly, as shown in FIG. 3B, the light distribution shape R becomes longer in the major axis direction of the ellipse (the left-right direction in FIG. 3B).
A flange 362 is provided on the outer peripheral edge of the lens member 36. The flange portion 362 is provided with a plurality (four in this case) of screw holes 363 at equal intervals.

透過カバー40は、透光性の樹脂からなる矩形枠状の取付板41を有しており、取付板41の上下両端部には、貫通穴42が設けられている。
なお、透過カバー40は、透明でもよく、あるいは乳白色といった光を拡散させるものでもよい。また、透過カバー40に設けられた貫通穴42は必須ではなく、透過カバー40を器具本体20に取付可能であれば構造は不問である。

Note that the transmissive cover 40 may be transparent or may diffuse light such as milky white. Further, the through hole 42 provided in the transmission cover 40 is not essential, and the structure is not limited as long as the transmission cover 40 can be attached to the instrument body 20.
The transmission cover 40 has a central portion 43 protruding forward in a substantially semi-cylindrical shape corresponding to the shapes of the instrument body 20 and the base 21. The central portion 43 has a pair of left and right side surfaces 44 and a pair of upper and lower end surfaces 45.
The central portion 43 of the transmissive cover 40 covers the front of the light source unit 30 attached to the base 21 of the instrument body 20.

次に、照明器具10の組立て方について説明する。
まず、LEDチップ32を実装した基板31を、台座21の上面212に取り付ける。次いで、照射方向からレンズ部材36を基板31に被せて、レンズ部材36のねじ孔363に取付ねじ37を通して、器具本体20の台座21に設けられている器具側ねじ孔22に締結する。
Next, how to assemble the lighting fixture 10 will be described.
First, the substrate 31 on which the LED chip 32 is mounted is attached to the upper surface 212 of the base 21. Next, the lens member 36 is placed on the substrate 31 from the irradiation direction, and the mounting screw 37 is passed through the screw hole 363 of the lens member 36 to be fastened to the instrument side screw hole 22 provided in the base 21 of the instrument body 20.

次いで、器具本体20の木ねじ部26の木ねじ用孔261に木ねじ(図示省略)を通して、器具本体20を壁面11に取り付ける。
そして、透過カバー40を器具本体20に被せて、固定ねじ25を透過カバー40の貫通穴42に通して、器具本体20のカバー用ねじ孔24に締付ける。
なお、固定ねじ25を外すことにより、透過カバー40を容易に取り外すことができる。
Next, the instrument main body 20 is attached to the wall surface 11 through a wood screw (not shown) through the wood screw hole 261 of the wood thread portion 26 of the instrument main body 20.
Then, the transparent cover 40 is put on the instrument main body 20, and the fixing screw 25 is passed through the through hole 42 of the transparent cover 40 and fastened to the cover screw hole 24 of the instrument main body 20.
The transmission cover 40 can be easily removed by removing the fixing screw 25.

照明器具10の作用効果について説明する。
器具本体20にはLEDチップ32およびLEDチップ32を覆うレンズ部材36が取り付けられ、器具本体20の照射方向は透過カバー40で覆われる。
そして、レンズ部材36のレンズ部361の表面を楕円形状に形成したので、器具本体20や透過カバー40が長尺矩形状である場合でも、長尺方向に配光でき、透過カバー40の全面にわたって均一な配光を行うことができる。
The effect of the lighting fixture 10 is demonstrated.
An LED chip 32 and a lens member 36 that covers the LED chip 32 are attached to the instrument body 20, and the irradiation direction of the instrument body 20 is covered with a transmission cover 40.
And since the surface of the lens part 361 of the lens member 36 was formed in an elliptical shape, even when the instrument main body 20 and the transmission cover 40 are long rectangular shapes, light can be distributed in the long direction, and the entire surface of the transmission cover 40 can be distributed. Uniform light distribution can be performed.

また、照明器具10では、器具本体20にLEDチップ32が取り付けられる台座21が設けられており、台座21の側面211と透過カバー40の内面401との間に空隙が設けられている。
このため、LEDチップ32からの光が、空隙を通って透過カバー40の側面44から照射される。
その上、台座21の側面211が反射面となって、台座21と透過カバー40との間で反復反射して、するので、全体が均一に発光する。
Further, in the lighting fixture 10, a pedestal 21 to which the LED chip 32 is attached is provided on the fixture body 20, and a gap is provided between the side surface 211 of the pedestal 21 and the inner surface 401 of the transmission cover 40.
For this reason, the light from the LED chip 32 is irradiated from the side surface 44 of the transmission cover 40 through the gap.
In addition, the side surface 211 of the pedestal 21 becomes a reflection surface, and is repeatedly reflected between the pedestal 21 and the transmission cover 40, so that the whole emits light uniformly.

さらに、照明器具10は、レンズ部361の頭頂部364の厚み寸法と、頭頂部364以外の周囲部365の厚み寸法とを異なるようにした。
このため、頭頂部364の厚み寸法小さくし、周囲部365の厚み寸法を大きくすることにより、長尺方向に広く配光することができる。
Further, the lighting fixture 10 is configured such that the thickness dimension of the head top part 364 of the lens part 361 is different from the thickness dimension of the peripheral part 365 other than the head top part 364.
For this reason, by reducing the thickness dimension of the top portion 364 and increasing the thickness dimension of the peripheral portion 365, it is possible to distribute light widely in the longitudinal direction.

本発明の照明器具は、前述した実施形態に限定されるものでなく、適宜な変形、改良等が可能である。
前述した実施形態では、LEDチップ32を実装した基板31をLEDチップ32を実装した基板31を台座21の上面212に取り付けた後、レンズ部材36を基板31に被せていたが、例えばLEDチップ32を実装した基板31を別部材のホルダ部材に固定した後、ホルダ部材をレンズ部材36に固定することによりレンズ部材36に基板31を取り付ける構造を採用してもよい。
The lighting fixture of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
In the above-described embodiment, the substrate 31 on which the LED chip 32 is mounted is attached to the upper surface 212 of the pedestal 21 after the substrate 31 on which the LED chip 32 is mounted, and then the lens member 36 is covered with the substrate 31. A structure in which the substrate 31 is attached to the lens member 36 by fixing the holder member to the lens member 36 after fixing the substrate 31 mounted with a holder member to another member may be employed.
