Description

本考案は矩形形状の額縁の縁辺筐体内部に照明装置を持ち、その底面に設置される図画、写真、文書あるいは工作物等被照明体（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 frame housing of a rectangular frame, and a frame, a photo stand, etc. for illuminating an object to be illuminated (hereinafter referred to as an illuminated object) such as a drawing, photograph, document or work set on the bottom surface thereof. The present invention relates to a device and a method for a display board (hereinafter referred to as a frame).

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が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は従来から存在する。しかし図画、写真等の画面が印刷または印画された紙や布等画材類あるいは押し花、キルティング、切り絵、刺繍布や立体的なレリーフや玩具等工作物類の現物をそのまま被照明体として照明表示できる額縁や類似の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, as a so-called “digital photo frame”, dedicated devices for displaying various digital photographic information obtained by a digital camera on a liquid crystal display device have been commercialized and are spreading. Conventionally, there is a display device that prints a photograph on a film or a transparent resin plate in a translucent state by a special method and irradiates the back surface with a so-called backlight light source. However, it is possible to illuminate and display objects such as paper and cloth with printed or printed screens such as drawings and photographs, or actual objects such as pressed flowers, quilting, cutouts, embroidery cloth, three-dimensional reliefs and toys. Devices such as possible picture frames and similar photo frames are not currently available on the market.

実願２００９−００７９４６Actual application 2009-007946

本考案は、筐体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ポスター大程度まで可能で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。The present invention provides a light source provided along the hollow interior of the casing wall surface, and the object to be illuminated mounted in the casing as it is has a relatively large surface area even though the thickness is small. Provide a frame that can be illuminated. The surface area of the object to be illuminated can be as large as a poster, and the thickness of the housing can be reduced to about several centimeters.

考案が解決しようとする課題Problems that the device tries to solve

前述のように額縁の筐体は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）壁面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通常考えられる。しかしこの際光源は被照明体を前方ななめ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いため該額縁筐体の縁辺壁面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. The structure which irradiates this to-be-illuminated body from the front with the light source accommodated in the peripheral part (edge part) wall surface of the frame housing which can be taken is considered normally. However, since the light source illuminates the object to be illuminated from the front at this time, the portion near the light source is bright and the portion far from the light source tends to be dark, so even if many illumination light sources are provided on the edge wall surface of the frame casing, There is a tendency that the peripheral part of the illuminating body 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.

課題を解決するための手段Means for solving the problem

本考案の照明付き額縁はその矩形筐体内の底面に被照明体を装着し、その周囲上方で体面して互いに向き合う一対の額縁縁辺部の筐体壁面内に光源を収納し、この光が額縁天面（上方）に設けられる底面（下方）方向に凸な断面形状のガラスあるいはアクリル等樹脂面（以下透明板）の表面で効率的に反射され主に額縁中央下方の底面の被照明体方向に向くよう照射され、別途直接的に被照明体に向かう光で明るくなりやすい該額縁縁辺部近傍とあわせて互いに補完し全体としてほぼ均等な照明効果が得られるよう設定される。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内部に設けて構成される。通常直線状光源から長手軸方向と直交する放射状方向に出射され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て略距離の二乗に反比例して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直達光だけでなく非直達光が該反射系で反射し光源より遠方まで到達して明るく照射し有効に活用されるとともに、相対する該縁辺部の光源で相互補完する全く新しい方法を用いることで解決する。The illuminated frame of the present invention has an illuminated body mounted on the bottom surface of a rectangular housing, and a light source is housed in a housing wall surface of a pair of frame edge sides facing the top of the periphery, and this light is transmitted to the frame. The direction of the object to be illuminated mainly on the bottom surface at the lower center of the frame is efficiently reflected on the surface of the glass or acrylic resin surface (hereinafter referred to as transparent plate) having a cross-sectional shape convex in the bottom surface (downward) direction provided on the top surface (upper) Are set so as to complement each other together with the vicinity of the frame edge that tends to be brightened by the light directly directed to the object to be illuminated, and obtain a substantially uniform illumination effect as a whole. The light source is configured by providing a linear light-emitting body such as a fluorescent tube or a cold cathode tube (CCFL) or a light-emitting diode (LED) appropriately arranged on a plurality of straight lines inside the frame. Usually, light emitted from a linear light source in a radial direction perpendicular to the longitudinal axis direction and directly reaching the object to be illuminated is diffused in a portion near the light source and diffused in a portion far away from the light source, and becomes dark in inverse proportion to the square of the distance. In this way, the illuminance of the object to be illuminated becomes uneven and it becomes difficult to obtain uniform and clear illumination. However, the present invention not only provides such inconvenience but also the non-direct light from the light source. The problem is solved by using a completely new method of reflecting and reaching far from the light source and illuminating brightly for effective use, and complementing each other with the light sources at the opposite edges.

発明の効果The invention's effect

本考案により、簡易に図画、写真、文書あるいは工作物等を新たに加工す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から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, or workpieces in a normal state can be used as a photo frame. It can also be used for commercial illuminated billboards, exhibition equipment, 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、図２、図３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、図３は図２の応用例である。本装置の構造は主に該照明付き額縁筐体の額縁筐体（１）、額縁縁辺部（２）額縁筐体中央の上部透明板（３）、株透明板（９）、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上部反射面（７）と下部反射面（７１）および照明される図画等被照明体（５）で構成される。Hereinafter, the present invention will be described with reference to application examples shown in FIGS. FIG. 1 is a schematic perspective view of the structure of an illuminated frame as a representative example of the apparatus according to the present invention, FIG. 2 is a sectional view taken along line XX in FIG. 1, and FIG. 3 is an application example of FIG. The structure of this device is mainly the frame case (1) of the illuminated frame case, the frame edge part (2), the upper transparent plate (3) in the center of the frame case, the stock transparent plate (9), the bottom surface of the case The main structure of (6) and the illumination light source (4) provided on the inner surface of the frame edge (2), a pair of upper reflection surface (7) and lower reflection surface (71) provided in the vicinity, and illumination It consists of an object to be illuminated (5).

図１におけるＹ−Ｙ線は該額縁筐体（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）の直下の該額縁筐体（１）の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に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、また図２の側断面にはこの線状光源（４）が中央のＣ−Ｃ線（一点鎖線で示す）の左右に対称的に設けられる状態を示す。本考案の作用効果を同図左側（同図Ａ側）の光源からの光の光路を実線矢印で、同図右側（同図Ｂ側）の光源から同光路を破線矢印で模式的に示す。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、その光路中特に太い実線及び破線で示すものは左右光源からそれぞれ筐体の底面（６）上に設けられる被照明体（５）に向かう直達光で、通常該被照明体（５）に近いＡ側は光量が相対的に多くて明るく逆に遠いＢ側は光量が少なくて暗くなる。この照度はほぼＡ側もしくはＢ側からの距離の二乗に反比例するため両者の照らす中央Ｃ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左右からの光路をそれぞれ細い実線及び破線で示すが上部反射面（７）および下部透明板（９）で反射され、左側からの光はＡ側より遠方のＢ側近くまで到達でき、逆に右側からの光はＢ側より遠方のＡ側に到達できる。ここに下部反射板（９）はその側断面が図２のように左右の額縁縁辺部（２）の上方端部に両端を有しその間を該筐体の底板（６）方向に凸な形状で、アクリル板やポリカーボ板等透明材料を曲線または直線と曲線の複合断面形状に形成して額縁筐体（１）の中央上部に設けられる。また上部反射面（７）は図２のように左右それぞれの額縁縁辺部（２）下方の額縁筐体（１）内で線状光源（４）と平行な方向に設けられるが、その一端は前記下部透明板（９）の額縁縁辺部（２）側と近接し他端は該線状光源（４）の上部近傍に設けられる。この組み合わせにより非直達光は上部反射面（７）及び下部透明板（９）に向かいそれぞれ反射面への入射角が小さくなり全反射の比率が増し、併せてより中央部やより遠方に方向を設定した反射が可能となる。以上により先述の直達光と合成して光源（４）からの光は光路矢印の示すようにほぼ均等に被照明体（５）を照射する。同図額縁上向きの中抜き矢印は均一な照明効果が得られることを模式的に示す。なお上部反射板（７）の下方の底面には下部反射面（７１）を設けると光源（４）からの光を適宜反射し、また下部透明板（９）の上方に重ねて平面状のガラス板やアクリル板の上部透明板（３）を設けると下部透明板（９）で全反射せず漏れた光もある程度下方の被照明体（５）に反射し、より照明効果を向上できる。The YY line in FIG. 1 indicates a generally longitudinal direction perpendicular to the paper surface of the frame housing (1), and is installed in the frame housing (1) immediately below the frame edge (2). When the light source (4) can be regarded as a linear light source such as a fluorescent tube or a CCFL, the longitudinal direction is set in a direction parallel to the light source. . The respective arrangement states are indicated by broken lines on the right side edge and the left side edge in FIG. 1, and the linear light source (4) is shown on the left and right sides of the central CC line (shown by a one-dot chain line) in the side cross section of FIG. The state provided symmetrically is shown. The operational effect of the present invention is schematically shown by the solid line arrow for the light path from the light source on the left side (A side in the figure) and the broken line arrow from the light source on the right side (B side in the figure). 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 and broken lines in the light path are respectively shown on the bottom surface (6) of the housing from the left and right light sources. In the direct light toward the illuminated body (5) provided on the A side, the A side close to the illuminated body (5) usually has a relatively large amount of light and is bright and on the contrary, the B side has a small amount of light and becomes dark. Since this illuminance is almost inversely proportional to the square of the distance from the A side or B side, the central C portion illuminated by both is darkest and uniform illuminance cannot be obtained. The light paths from the left and right other than the direct light directed to the directly illuminated body (5) are indicated by thin solid lines and broken lines, respectively, but are reflected by the upper reflecting surface (7) and the lower transparent plate (9), and the light from the left side is A The light from the right side can reach the A side which is farther from the B side. Here, the lower reflector (9) is shaped so that the side cross section has both ends at the upper ends of the left and right frame edges (2) as shown in FIG. 2, and the space between them protrudes toward the bottom plate (6) of the housing. Thus, a transparent material such as an acrylic plate or a polycarbonate plate is formed in a curved or straight and curved composite cross-sectional shape and provided at the upper center of the frame housing (1). The upper reflecting surface (7) is provided in the direction parallel to the linear light source (4) in the frame housing (1) below the left and right frame edge portions (2) as shown in FIG. The lower transparent plate (9) is close to the frame edge (2) side and the other end is provided near the upper portion of the linear light source (4). With this combination, the non-direct light is directed toward the upper reflecting surface (7) and the lower transparent plate (9), the angle of incidence on the reflecting surface is reduced, and the ratio of total reflection is increased. The set reflection is possible. As described above, the light from the light source (4) combined with the direct light described above irradiates the illuminated body (5) almost evenly as indicated by the optical path arrow. A hollow arrow pointing upward in the figure schematically shows that a uniform illumination effect can be obtained. If a lower reflecting surface (71) is provided on the bottom surface below the upper reflecting plate (7), the light from the light source (4) is appropriately reflected, and the flat glass is superimposed on the lower transparent plate (9). When the upper transparent plate (3) such as a plate or an acrylic plate is provided, the light that does not totally reflect on the lower transparent plate (9) and is leaked is reflected to the lower illuminated body (5) to some extent, and the illumination effect can be further improved.

なお、図２に示すように本考案によれば光源（４）から被照明体（５）への直達光より非直達光の比率を増すほうがより均一な照明が得やすい。このため同断面図での光源（４）からの放射光はその主な割合が適宜下部透明板（９）に向かうように設定する。同図でＬ−Ｌ線は光源（４）からの中心的な光路で前記状態を模式的に示す。As shown in FIG. 2, according to the present invention, it is easier to obtain more uniform illumination by increasing the ratio of non-directly reaching light than directly reaching the illuminated body (5) from the light source (4). For this reason, the main ratio of the emitted light from the light source (4) in the same sectional view is set so as to be directed to the lower transparent plate (9) as appropriate. In the same figure, the LL line | wire shows the said state typically with the central optical path from a light source (4).

また図３の側断面図で示すように光源（４）が蛍光管やＣＣＦＬ等では光路（図示せず）がその背面にも向かうので略放物線断面の反射鏡（１０）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の集光できるレンズ（１１）を設けたりして光路（図示せず）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（８）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（１０）、レンズ（１１）あるいは光拡散板（８）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。Further, as shown in the side sectional view of FIG. 3, when the light source (4) is a fluorescent tube, CCFL, or the like, the optical path (not shown) is directed to the back side, so The light path (not shown) is reflected by reflecting in the direction of the illuminating body, or by providing a substantially convex condensing lens (11) that refracts within an appropriate solid angle in front of an individual point light source such as an LED. ) To supplement the purpose of the present invention. In the case of an LED light source, if a transparent or translucent light diffusing plate (8) is provided in the optical path, the illumination effect may be improved by bringing it closer to the characteristics of the line light source. The reflecting mirror (10), the lens (11), and the light diffusing plate (8) are all stored below the frame edge (2) so that they cannot be seen from above the frame housing.

なお、本考案で示した下部透明板（９）と上部反射板（７）は一体的に形成することも可能でより取り扱い我容易になり反射効果も安定することが期待できる。また、本考案の方式は説明に用いた一対の対象位置の額縁縁辺部（２）以外の残りの縁辺部にも同様に応用できる表面積が大きい場合より効果が発揮できる。It should be noted that the lower transparent plate (9) and the upper reflector (7) shown in the present invention can be integrally formed, and can be expected to be easier to handle and stabilize the reflection effect. Further, the method of the present invention can be more effective than the case where the surface area that can be similarly applied to the remaining edge portions other than the frame edge portion (2) of the pair of target positions used in the description is large.
