Description
本考案は箱型形状の額縁の縁辺内部に照明装置を持ち、その底面に設置される図画や写真あるいは文書等被照明体(以下被照明体)を照明する額縁、写真立て、表示板等(以下額縁等)の装置および方式に関するものである。The present invention has a lighting device inside the edge of a box-shaped picture frame, and a picture frame, a photo stand, a display board, etc. that illuminates an object to be illuminated (hereinafter called the object to be illuminated) such as a picture, photograph or document installed on its bottom surface ( The following description relates to a frame and the like device and method.
近年いわゆる「デジタルフォトフレーム」としてデジタルカメラで得たデジタルの写真情報を液晶表示装置で多様に表示する専用機器は商品化され広まりつつある。また写真をフィルムや透明な樹脂板に特別の方法で半透明状態に印刷しその背面からいわゆるバックライト光源で照射する表示装置も存在するが、下記文献のように図画や写真等の画面が印刷あるいは印画された紙や布等画材の現物をそのまま照明表示する額縁や写真立てのような装置は現時点で市場ではほとんど確認できない。In recent years, dedicated devices that display various digital photographic information obtained by digital cameras as so-called “digital photo frames” on a liquid crystal display device have been commercialized and are becoming widespread. There is also a display device that prints a photograph or film on a transparent resin plate in a semi-transparent state using a special method and irradiates it with a so-called backlight light source from the back. However, as shown in the following document, screens such as drawings and photographs are printed. Alternatively, devices such as a picture frame and a photo stand that illuminate and display the actual printed material such as paper or cloth can hardly be confirmed in the market at present.
登録実用新案第3154022号Registered Utility Model No. 3154022
実願2009−007946Actual application 2009-007946
本考案は、筐体外周壁面の中空内部に沿って設けられた光源で該筐体内に装着された被照明体をそのままの状態で厚みが小さいわりに比較的大きな表面積を有するにもかかわらずほぼ均等に照明できる額縁を提供する。被照明体の表面積は例えばハガキより大きくポスター程度までとし筐体の厚みは数センチ程度以下の実用的な形態を実現する。In the present invention, a light source provided along the hollow inside of the outer peripheral wall surface of the casing is substantially uniform despite having a relatively large surface area although the thickness of the illuminated object mounted in the casing is small as it is. Provide a picture frame that can be illuminated. The surface area of the object to be illuminated is, for example, larger than a postcard up to about a poster, and the housing has a thickness of about several centimeters or less to realize a practical form.
前述のように額縁の筐体は図画等被照明体の表面積に比しその厚みが小さいため被照明体を該筐体の底面中央部に特に加工せず配設しその表面側で比較的内部空間のとれる額縁筐体の周辺部(縁辺部)内に収納した光源で該被照明体を前方から照射する構成が自然である。しかしこの際光源は被照明体をななめ横から照明することになるので光源に近い部分は明るく遠い部分は暗くなりやすく従って該額縁周囲の縁辺部内に多くの照明用光源を設けても被照明体の周辺部は明るく中央部は暗くなって均等に照明されない傾向がある。本考案はこのような構成にあっても被照明体をほぼ均一な照度で照明するため、光源の形態、光路の反射や屈折の仕方および被照明体との相互位置関係等を最適になるよう構成し簡単な構造ながら均等で鮮明な照明付き額縁の実現を図る。As described above, the frame casing is smaller in thickness than the surface area of the object to be illuminated, such as a drawing. It is natural to irradiate the object to be illuminated from the front with a light source housed in a peripheral part (edge part) of a frame housing where space is available. However, at this time, the light source illuminates the illuminated body from the side, so that the portion near the light source is bright and the far portion is likely to be dark, so even if many illumination light sources are provided around the frame, the illuminated body There is a tendency that the peripheral part of the light is bright and the central part is dark and not uniformly illuminated. Since the present invention illuminates the illuminated body with almost uniform illuminance even in such a configuration, the configuration of the light source, the way of reflection and refraction of the optical path, the mutual positional relationship with the illuminated body, etc. are optimized. A simple and well-structured frame with uniform and clear lighting will be realized.
本考案の照明付き額縁はその箱型筐体内の底面に被照明体を装着し、その周囲上方の額縁縁辺部の内側に設けられた空間の外壁側に光源を収納するが、その主軸光が額縁上面に設けられる透明ガラスあるいはアクリル等樹脂面(以下透明板)にほぼ平行もしくはわずかに下方の底面の被照明体方向に向いて出射されるように設定される。該光源は蛍光管や冷陰極管(CCFL)のような線状の発光体あるいは発光ダイオード(LED)を複数直線上に適宜並べたものを該額縁の一縁辺もしくは二縁辺以上の内部に設けて構成し、該光源から放射状に出射される光が直接的に該被照明体を照射すると同時に、直達しない光は該額縁の縁辺部及び向かい合う底面の内側で相対するように設けられる一対の反射面や上面の該透明板の内側裏面とで構成される反射系で反射され該被照明体を照明する。ここに前記の該被照明体に直達する光は光源に近い部分は明るく遠く離れた部分は拡散した光があたるのでより暗くなり前述のように被照明体の照度にはムラが生じ均質で鮮明な照明が得にくくなってしまうが、本考案はこのような不都合を光源からの非直達光を該反射系の反射で光源より遠方まで照射されるよう有効に活用する方法を用いることで抑制もしくは解消する。特に該光源の額縁縁辺部の対抗側に前記と同様な光源と反射面を配設すると両光源が一対となって相互に照度を補完できるためより均等な照度の照明が可能となる。The illuminated frame of the present invention has an illuminated body mounted on the bottom surface in the box-shaped housing, and the light source is stored on the outer wall side of the space provided on the inner side of the frame edge on the upper periphery of the frame. It is set so as to be emitted toward the object to be illuminated on the bottom surface substantially parallel or slightly below the transparent glass or acrylic resin surface (hereinafter referred to as transparent plate) provided on the upper surface of the frame. The light source is a linear light-emitting body such as a fluorescent tube or a cold cathode fluorescent lamp (CCFL) or a light-emitting diode (LED) arranged appropriately on a plurality of straight lines, provided inside one or more edges of the frame. A pair of reflecting surfaces are provided so that light emitted radially from the light source directly irradiates the object to be illuminated, and light that does not reach directly is opposed to the inside edge of the frame edge and the opposite bottom surface. Further, the object to be illuminated is illuminated by being reflected by a reflection system constituted by the inner and rear surfaces of the transparent plate on the upper surface. Here, the light directly reaching the object to be illuminated is brighter in the part near the light source and brighter in the part far away from the light source, so that it becomes darker and the illuminance of the object to be illuminated becomes uneven and uniform and clear as described above. However, the present invention suppresses such inconvenience by using a method of effectively utilizing non-direct light from the light source so that it is irradiated farther than the light source by reflection of the reflection system. Eliminate. In particular, when a light source and a reflective surface similar to those described above are provided on the opposite side of the frame edge of the light source, the two light sources can be paired to complement each other and the illumination can be more evenly illuminated.
本考案により、簡易に図画や写真や文書等を新たに加工されることなく通常状態のまま比較的大きい画面でも均等な明るさで前面より照明できる額縁は写真立てとして転用できるのはもちろん、業務用の照明付き広告板、展示装置、表示板等にも活用できる。本考案により、飾りたいものや思い出の品を明るく照らしてより美しく演出し見る人に安らぎを与え、また人目をひきたい事物を鮮明に強く訴求でき併せて夜間照明にも利用できる新商品分野の開拓が期待できる。With the present invention, a picture frame that can be illuminated from the front with a uniform brightness even on a relatively large screen without changing the drawings, photos, documents, etc. in a normal state can be used as a photo frame. It can also be used for illuminated advertising boards, display devices, display boards, etc. In this new product field, the present invention brightly illuminates the things you want to decorate and memories, and gives you more peace of mind and gives you peace of mind. Pioneering can be expected.
以下、本考案を図1および図2の応用実施例について説明する。図1は本考案による装置の代表例としての照明付き額縁の構造の概略斜視図であり、図2は図1のX−X側断面図である。本装置の構造は主に該照明付き額縁筐体の本体(1)、額縁縁辺部(2)額縁筐体上部中央の透明板(3)、筐体の底面(6)の主構造体と額縁縁辺部(2)の内面に設けられた照明用の光源(4)、近傍に設けられる一対の反射面(7)および照明される図画、写真等被照明体(5)で構成される。Hereinafter, the present invention will be described with reference to application examples of FIGS. FIG. 1 is a schematic perspective view of a structure of an illuminated frame as a representative example of the device according to the present invention, and FIG. 2 is a sectional view taken along line XX in FIG. The structure of the apparatus is mainly the main body (1) of the illuminated frame case, the frame edge (2) the transparent plate (3) at the upper center of the frame case, and the main structure and the frame on the bottom surface (6) of the case. An illumination light source (4) provided on the inner surface of the edge portion (2), a pair of reflection surfaces (7) provided in the vicinity, and an object to be illuminated (5) such as illuminated drawings and photographs.
図1におけるY−Y線は該額縁本体(1)の筐体の紙面に垂直な概して長手方向を示し、額縁縁辺部(2)内に設置される光源(4)はその形態が蛍光管やCCFL等線状光源とみなせる場合はその長手方向をこれと平行な方向に、複数のLEDを適宜並べる場合は同様平行な直線上に適宜装着する。それぞれの配設状態を図1の右側縁辺部および左側縁辺部に破線で示す。図2の側断面はこの線状光源(4)から出射された光の光路で本考案の作用効果を示す。光源(4)からはその側断面方向には筐体内部方向に放射状に光が発散されるが、その光路中太い実線で示すものは筐体の底面(6)上に設けられる被照明体(5)に向かう直達光で、特に光源(4)が長手方向の光の発散を屈折や反射により制御されない通常の場合該被照明体(5)に近いA部は光量が多くて明るく逆に遠いB部は光量が少なくて相対的に暗くなる。この照度はほぼA部からの距離の二乗に反比例するため仮にこの対抗する反対側に同様光源を設けて補完しようとしても両者の照らす中央部は最も暗くなり均等な照度は得られない。上記直接被照明体(5)に向かう直達光以外の光路を破線、鎖線等で示すが反射面(7)および透明板(3)で反射されA部より遠方のB部近くまで到達できる。これは同図のように額縁縁辺部(2)内で下方向きに設けられる反射面(7)及びその対抗する下方の底面の一部に設けられる反射面(7)で光が一回あるいは複数回反射してから被照明体(5)に向かったり、透明板(3)に至ってここで再度反射してから被照明体(5)に向かったりしてより遠方に運ばれるためである。この結果光源より離れた位置まで被照明体(5)は照らされ照度は大きく改善される。なお透明板(3)には光の入射角が十分小さい(5度程度以下)とき全反射となり遠方の照明に効果が大きくなるのでなるべくこれに近くなるよう光源(4)と光の主軸(図2の2点鎖線で示す)方向及び反射面(7)の組み合わせや位置等は設定される。具体的には光源(4)を上方に持ち上げ、光主軸方向を透明板(3)と平行ないしやや下方とすると全反射を得やすくなるが光源(4)の形態、額縁の形状、透明板(3)の特性から総合的に判断し相互の位置や形態は適宜決定される。The Y-Y line in FIG. 1 indicates a generally longitudinal direction perpendicular to the paper surface of the casing of the frame body (1), and the light source (4) installed in the frame edge (2) is in the form of a fluorescent tube or When it can be regarded as a CCFL equilinear light source, its longitudinal direction is set in a direction parallel to this, and when a plurality of LEDs are arranged as appropriate, it is appropriately mounted on a parallel straight line. Each arrangement | positioning state is shown with a broken line in the right side edge part and left side edge part of FIG. The side cross section of FIG. 2 shows the effect of the present invention in the optical path of the light emitted from the linear light source (4). Light is emitted radially from the light source (4) toward the inside of the housing in the direction of the side cross section, but the thick solid line in the optical path indicates the illuminated object (on the bottom surface (6) of the housing) In the normal case where the light source (4) is not directly controlled by refraction or reflection, the A part close to the illuminated body (5) has a large amount of light and is far away. Part B is relatively dark with a small amount of light. Since this illuminance is almost inversely proportional to the square of the distance from the A portion, even if a similar light source is provided on the opposite side, the central portion illuminated by both is darkest and uniform illuminance cannot be obtained. An optical path other than the direct light directed to the directly illuminated body (5) is indicated by a broken line, a chain line, etc., but is reflected by the reflecting surface (7) and the transparent plate (3) and can reach the B portion farther from the A portion. As shown in the figure, the light is emitted once or plural times on the reflecting surface (7) provided downward in the frame edge (2) and the reflecting surface (7) provided on a part of the bottom surface facing the same. This is because after being reflected once, it goes to the illuminated body (5), or reaches the transparent plate (3) and reflects again here, and then goes toward the illuminated body (5) and is carried further away. As a result, the illuminated object (5) is illuminated to a position away from the light source, and the illuminance is greatly improved. The transparent plate (3) is totally reflected when the incident angle of light is sufficiently small (about 5 degrees or less), and the effect on distant illumination is increased, so that the light source (4) and the main axis of light (see FIG. 2) (indicated by a two-dot chain line), and the combination and position of the reflecting surface (7). Specifically, if the light source (4) is lifted upward and the optical principal axis direction is parallel to or slightly below the transparent plate (3), total reflection can be easily obtained, but the form of the light source (4), the shape of the frame, the transparent plate ( The position and form of each other are appropriately determined by comprehensively judging from the characteristics of 3).
光源(4)が蛍光管やCCFL等では光路がその背面にも向かうので略放物線断面の反射鏡(8)で前方(筐体内被照明体方向)に反射させたり、LEDのように個々には点光源では前方に適当な立体角内に屈折する略凸形レンズ(81)を設けたりして光路を整え本考案の目的を補足し得る。また、LED光源の場合光路中に透明あるいは半透明な光拡散板(9)を設けるとより線光源の特性に近づけ照明効果も向上することがある。該反射鏡(8)、レンズ(81)あるいは光拡散板(9)はいずれも額縁縁辺部(2)の下方に収納され額縁筐体の上方からは見えないようにされる。なお、図2のように右側の筐体本体(1)の壁面内側に反射面(7)を設け直達光の一部や透明板(3)からの反射光を反射して被照明体(5)のB部近傍の照明の向上に供することも可能であるが、通常は図1のように相対する一対の額縁縁辺部(2)にそれぞれ光源と反射系を設けて既述のように両光源による照度補完作用により略均一な照明効果を得るようにする。残りの各額縁縁辺部(2)にも同上の光源と反射系を設けることはさらに全体の照度向上になり必要応じて設定され得る。When the light source (4) is a fluorescent tube, CCFL, etc., the optical path is also directed to the back side, so that it is reflected forward (toward the body to be illuminated) by the reflecting mirror (8) having a substantially parabolic cross section, or individually like an LED. In the point light source, the object of the present invention can be supplemented by adjusting the optical path by providing a substantially convex lens (81) that refracts within an appropriate solid angle forward. In the case of an LED light source, if a transparent or semi-transparent light diffusing plate (9) is provided in the optical path, the illumination effect may be improved closer to the characteristics of the line light source. The reflecting mirror (8), the lens (81), and the light diffusing plate (9) are all stored below the frame edge (2) so that they cannot be seen from above the frame housing. As shown in FIG. 2, a reflecting surface (7) is provided inside the wall surface of the right casing body (1) to reflect a part of the direct light or the reflected light from the transparent plate (3) to illuminate the object (5 It is possible to improve the illumination in the vicinity of part B), but usually a light source and a reflection system are provided on each of the pair of opposite frame edge parts (2) as shown in FIG. A substantially uniform illumination effect is obtained by the illuminance complementing action by the light source. Providing the same light source and reflection system in each of the remaining frame edges (2) further improves the overall illuminance and can be set as necessary.
