Description

【０００１】
【発明の属する技術分野】
本発明は、防雨型照明器具に関するものである。
【０００２】
【従来の技術】
建築照明における照明計画の中では、壁面や天井面を均斉度よく照射することが要求される。近年、特に照射面の均斉度は、よりシビアなものが市場から求められており、壁面取付用の照明器具等のように照射面に接近して設けられ、取り付け面に対して垂直方向の面に設けた透光開口部から照射面を照射するものにおいては、均斉度が高い照明器具が要求される。
【０００３】
従来の直付型照明器具においては、ランプ及び反射鏡を内部に配置した器具本体の照射方向側の面に、透光パネルを器具本体の最外面より内側に配置して、照射方向自在型とした防雨型照明器具があった（例えば、特許文献１参照。）。
【０００４】
図２１〜２３は従来の照明器具を示し、開口に角型のガラスパネル１０４が嵌め込まれた枠１０２をケース１０３の上面の開口部１０３ａに被装し、ケース１０３内部にはランプソケット１１０、ランプソケット１１０に嵌装されたランプ１１１が配設されている器具本体１３０と、器具本体１３０に設けられるアーム１４０と、アーム１４０の端部に設けられるフランジ１５０とを備えている。
【０００５】
ケース１０３内のランプ１１１周囲にはランプ１１１が発する光をガラスパネル１０４を介して外部に配光する反射板１１２が設けられている。そして、取付面Ｍに固定された取付板１７０に立設したボルトをフランジ１５０の挿通孔に挿通し、挿通孔から突出したボルトの先端部に締付ナット１６０を締め付けることでフランジ１５０が取付板１７０に取り付けられ、照明器具を取付面Ｍに取り付けるようになっている。そして、アーム１４０を回動させることで器具本体１３０のガラスパネル１０４の向きを調節して、照射方向を調整している。
【０００６】
ガラスパネル１０４の枠１０２への取付部Ｃは図２４に示すように、ガラスパネル１０４は、枠１０２の開口周縁に沿って断面コの字型に形成されたパッキン１０５の凹部にその周縁部を嵌めた状態で取り付けられており、パッキン１０５によってガラスパネル１０４と枠１０２との隙間から器具本体１３０内部に水が入らないように防水され、パッキン１０５はその全周に亘って上方を枠１０２に覆設されている。
【０００７】
また、図２５はパッキン１０５の代わりにコーキング１３５を用いた照明器具の側面から見た一部断面図を示しており、上面から見た一部破断図、側面図は図２１，２２と各々同様である。ガラスパネル１０４の枠１０２への取付部Ｄは図２６に示すように、ガラスパネル１０４は、枠１０２の開口周縁に沿って断面Ｌ字型の枠型に形成されたコーキング１３５上にその周縁部を配した状態で取り付けられており、コーキング１３５によってガラスパネル１０４と枠１０２との隙間から器具本体１３０内部に水が入らないように防水されている。

【発明が解決しようとする課題】
上記パッキンを用いた従来の照明器具は、上方に光を照射させると透光パネル面に雨水が溜まることがある。雨水が溜まると、溜まった雨水の模様が照射面に出たり、ランプの熱によって雨水が蒸発して水蒸気が発生し、光が妨げられたり、あるいは透光パネル面が汚れることによって、光量低下の原因となっていた。さらに、透光パネル面に雨水が溜まった状態で、ランプ点灯時から消灯時に本体内部が外部より負圧になると、溜まった雨水が本体内部へ吸い込まれて内部が浸水する危険性もあった。
【００１０】
また、透光パネルに雨水が溜まらないように透光パネル面を、器具本体の最外面に連続した同一面とし、その透光パネルと器具本体との接触部分にコーキング等を施すことによって、透光パネルを固定したものもあるが、この構成では組み立て性が悪く、外観上もコーキング等が露出して外観も悪く、さらにコーキング部に直射日光が当たる場合、紫外線による劣化によって防水性能が低下し、本体内部が浸水する危険性があった。
【００１１】
本発明は、上記事由に鑑みてなされたものであり、その目的は透光パネル面に溜まる雨水による光量低下を防止し、且つ防水部材の劣化を防いだ外観のよい防雨型照明器具を提供することにある。
【００１２】

【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１６】
（基本構成１）
本基本構成の防雨型照明器具は建築物等の取り付け面に取り付けられるもので、図１は器具本体１の外観斜視図、図２は器具本体１の取り付け状態における上面から見た一部破断図、図３は器具本体１の取り付け状態における側面断面図を各々示す。器具本体１は、角型のガラスパネル４（透光パネル）が開口の内面側に嵌め込まれた枠２（カバー）をケース３の上面の開口部３ａに被装し、ケース３内部にはランプソケット１０、ランプソケット１０に嵌装された両口金型ＨＩＤランプ１１が配設されている。

【発明の効果】
請求項１の発明は、器具本体の中に配置したランプ及び反射鏡と、器具本体上面の開口部に覆設されて、器具本体の外面よりも内側に位置する透光パネルと、透光パネルの周縁部において、器具本体と透光パネルとの隙間を塞ぐと共に透光パネルを固定する防水部材と、透光パネルを露出する開口を有して防水部材に上方から覆設するカバーとを備えて、取付面に直付される防雨型照明器具において、カバーの開口の一辺は、当該一辺に対向する他辺側より下方に位置するとともに、２つの斜辺によって当該開口の外側に向かう突出部を形成され、防水部材は、前記開口の突出部において透光パネルの上面に連続した面を有し、カバーは、透光パネルの上面に連続した防水部材の面に連続した底面を有して両端を開口した溝部を器具本体の外縁にまで形成すると共に、該溝部に連続する防水部材をその上方に空間を設けて覆う外郭を有し、透光パネルの上面に溜まった水が溝部に沿って器具本体外部に排出されるように透光パネルの上面は傾斜しているので、透光パネル面に雨水が溜まり、溜まった雨水の模様が照射面に出たり、ランプの熱によって雨水が蒸発して水蒸気が発生して光が妨げられること、あるいは透光パネル面が汚れることによる光量低下を防止したり、透光パネル面に雨水が溜まった状態で、ランプ点灯時から消灯時に本体内部が外部より負圧になった場合に、溜まった雨水が本体内部へ吸い込まれて内部が浸水する危険性を低減することができるという効果がある。また、防水性を確保するためにコーキング等は不要となり、組立性が向上する。また、カバーによって防水部材を覆うのでパッキン等の防水部材が露出せず外観が良くなり、防水部材に直射日光が当たらず、紫外線が原因の劣化による防水性能の劣化を防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a rainproof luminaire.
[0002]
[Prior art]
In the lighting plan for architectural lighting, it is required to illuminate the wall surface and ceiling surface evenly. In recent years, there has been a demand for a more severe degree of uniformity of the irradiated surface from the market, and it is provided close to the irradiated surface, such as a lighting fixture for wall mounting, and is a surface perpendicular to the mounting surface. In the case of irradiating the irradiation surface from the light-transmitting opening provided in the lighting device, a lighting device having a high uniformity is required.
[0003]
In a conventional direct-mounted illumination fixture, a light-transmitting panel is arranged by placing a translucent panel on the inner side of the outermost surface of the fixture main body on the surface of the fixture main body in which the lamp and the reflector are arranged. There was a rainproof type lighting fixture (see, for example, Patent Document 1).
[0004]
21 to 23 show conventional lighting fixtures, in which a frame 102 in which a square glass panel 104 is fitted in an opening is covered in an opening 103a on the upper surface of a case 103, and a lamp socket 110 and a lamp are provided inside the case 103. The instrument main body 130 in which the lamp | ramp 111 fitted by the socket 110 is arrange | positioned, the arm 140 provided in the instrument main body 130, and the flange 150 provided in the edge part of the arm 140 are provided.
[0005]
A reflector 112 that distributes light emitted from the lamp 111 to the outside through the glass panel 104 is provided around the lamp 111 in the case 103. Then, the bolt 150 standing on the mounting plate 170 fixed to the mounting surface M is inserted into the insertion hole of the flange 150, and the tightening nut 160 is tightened to the tip of the bolt protruding from the insertion hole, whereby the flange 150 is attached to the mounting plate. The lighting fixture is attached to the mounting surface M. And the direction of the glass panel 104 of the instrument main body 130 is adjusted by rotating the arm 140, and the irradiation direction is adjusted.
[0006]
As shown in FIG. 24, the attachment portion C of the glass panel 104 to the frame 102 has a peripheral portion in the concave portion of the packing 105 formed in a U-shaped cross section along the opening peripheral edge of the frame 102. It is attached in a fitted state and is waterproofed by the packing 105 so that water does not enter the interior of the instrument main body 130 through the gap between the glass panel 104 and the frame 102. The packing 105 extends upward to the frame 102 over its entire circumference. It is laid.
[0007]
25 shows a partial cross-sectional view as seen from the side of a lighting fixture using a caulking 135 instead of the packing 105. The partially cutaway view and the side view as seen from the top are the same as FIGS. It is. As shown in FIG. 26, the mounting portion D of the glass panel 104 to the frame 102 has a peripheral portion on a coking 135 formed in a frame shape having an L-shaped cross section along the opening peripheral edge of the frame 102. And is waterproofed by caulking 135 so that water does not enter the instrument main body 130 from the gap between the glass panel 104 and the frame 102.

[0009]
[Problems to be solved by the invention]
When the conventional lighting fixture using the packing is irradiated with light upward, rainwater may accumulate on the translucent panel surface. When rainwater accumulates, the pattern of accumulated rainwater appears on the irradiated surface, the rainwater evaporates due to the heat of the lamp and water vapor is generated, the light is obstructed, or the translucent panel surface is soiled. It was the cause. Further, when rainwater is accumulated on the surface of the translucent panel and the inside of the main body becomes negative pressure from the outside when the lamp is turned on or off, there is a risk that the accumulated rainwater is sucked into the main body and the inside is flooded.
[0010]
In order to prevent rainwater from collecting on the translucent panel, the translucent panel surface is made to be the same surface as the outermost surface of the instrument body, and caulking or the like is applied to the contact portion between the translucent panel and the instrument body. Some panels have a light panel fixed, but this structure is not easy to assemble, the appearance of the caulking is exposed and the appearance is also bad, and if the caulking part is exposed to direct sunlight, the waterproof performance decreases due to deterioration due to ultraviolet rays. There was a risk of the inside of the main unit being flooded.
[0011]
The present invention has been made in view of the above reasons, and its purpose is to provide a rainproof luminaire having a good appearance that prevents a decrease in the amount of light due to rainwater accumulated on the surface of the translucent panel and prevents deterioration of the waterproof member. There is to do.
[0012]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a lamp and a reflecting mirror disposed in an instrument main body, a translucent panel that is covered with an opening on the upper surface of the instrument main body and is located on the inner side of the outer surface of the instrument main body, and a translucent panel A waterproof member that closes a gap between the instrument body and the translucent panel and fixes the translucent panel, and a cover that covers the waterproof member from above with an opening that exposes the translucent panel. In the rainproof luminaire directly attached to the mounting surface, one side of the opening of the cover is located below the other side facing the one side, and the protruding portion that faces the outside of the opening by two oblique sides The waterproof member has a surface continuous with the upper surface of the translucent panel at the projecting portion of the opening, and the cover has a bottom surface continuous with the surface of the waterproof member continuous with the upper surface of the translucent panel. The groove that is open at both ends In addition, a waterproof member that is continuous with the groove is provided with a space to cover the waterproof member so that water accumulated on the upper surface of the translucent panel is discharged outside the instrument body along the groove. The upper surface of the translucent panel is inclined.
[0013]
According to a second aspect of the present invention, in the first aspect, the groove portion of the cover is formed on both sides of the side portion substantially perpendicular to the inclined direction of the inclined surface of the light transmitting panel at the peripheral edge portion of the opening exposing the light transmitting panel. It is characterized by that.
[0014]
According to a third aspect of the present invention, in the first aspect, the translucent panel has a shape with a gradient in cross section, and the groove portion of the cover is translucent at a peripheral portion of the opening exposing the translucent panel. It is formed in the location located under the inclined surface of a panel.
[0015]

The groove that is open at both ends In addition, a waterproof member that is continuous with the groove is provided with a space to cover the waterproof member so that water accumulated on the upper surface of the translucent panel is discharged outside the instrument body along the groove. Since the upper surface of the translucent panel is inclined, rainwater accumulates on the translucent panel surface, the rainwater pattern that accumulates appears on the irradiated surface, and the rainwater evaporates due to the heat of the lamp, generating water vapor and hindering light Or when the inside of the main unit becomes negative pressure from the outside when the lamp is turned on with the rainwater collecting on the translucent panel surface. There is an effect that the risk that the accumulated rainwater is sucked into the main body and the inside is submerged can be reduced. Moreover, in order to ensure waterproofness, caulking or the like is unnecessary, and assemblability is improved. Further, since the waterproof member is covered with the cover, the waterproof member such as packing is not exposed and the appearance is improved. The waterproof member is not exposed to direct sunlight, and the deterioration of the waterproof performance due to the deterioration caused by the ultraviolet rays can be prevented.
