Description

本発明はバルブの構造技術に係り、特に複数のＬＥＤ素子を光源としたＬＥＤバルブ及びそのランプカバーに関する。   The present invention relates to a bulb structure technique, and more particularly to an LED bulb using a plurality of LED elements as a light source and a lamp cover thereof.

近年、ＬＥＤは他の発光体に較べて節電、使用寿命が長い等の長所を有するために次第に広く照明器具に運用されるようになった。しかし、ＬＥＤ素子の照度はパワーアップ上の技術困難に制限されるため、照明器具の輝度をアップするためにはＬＥＤ素子の使用数量を増さねばならない。ＬＥＤ素子と伝統の発光体との違いは、発生する光線が特定エリア角度に集中するという特性であり、同一照明器具に複数のＬＥＤ素子が取り付けられると、多重光線、多明点の問題を発生し得る。多重光線、多明点は照射不均一、被照射物に多重陰影の状況を形成しやすく、観る者にちらつきをもたらし、視力を損傷することもある。   In recent years, since LEDs have advantages such as power saving and longer service life than other light emitters, they have been increasingly used in lighting fixtures. However, since the illuminance of the LED element is limited to technical difficulties in powering up, the number of LED elements used must be increased in order to increase the luminance of the lighting fixture. The difference between LED elements and traditional illuminants is the characteristic that the generated light rays are concentrated at a specific area angle. When multiple LED elements are attached to the same lighting fixture, the problem of multiple rays and multi-bright spots occurs. Can do. Multiple rays and bright spots are unevenly irradiated, and it is easy to form multiple shadows on the irradiated object, causing flickering to the viewer and damaging visual acuity.

図１及び図２は周知の複数のＬＥＤ素子を具えた照明器具表示図（一）、（二）である。一般に複数のＬＥＤ素子９０多重光線照射時に発生する欠点を改善する技術手段は、図１に示されるように、ランプカバー９１に若干の屈折紋９２を設けて、各ＬＥＤ素子９０の発生する光線を屈折紋９２の屈折作用により拡散させる、というものである。また、図２に示されるように、ランプカバー９１に対してフロスト処理する方式により、各ＬＥＤ素子９０の発生する光線を比較的柔和な方式で拡散照射させられる。   FIG.1 and FIG.2 is a lighting fixture display figure (1) and (2) which provided the some well-known LED element. In general, as shown in FIG. 1, a technical means for improving a defect that occurs when a plurality of LED elements 90 are irradiated with multiple light beams is provided with a slight refraction pattern 92 on a lamp cover 91 so that the light beams generated by the LED elements 90 are emitted. It is diffused by the refractive action of the refractive pattern 92. Further, as shown in FIG. 2, the light generated by each LED element 90 can be diffused and irradiated in a relatively soft manner by the frost processing method for the lamp cover 91.

上述の従来の技術における光線拡散の手段が現出させる改善効果は予期されたような理想的なものではなく、多重光線、多明点、照射不均一、被照射物の有する多重陰影等の問題は依然として有効に抑制されない。これについて本発明者が研究して分かったことは、周知の技術の改善効果が予期されたものとならない主要な原因は、複数のＬＥＤ素子が光線を発射する時、ランプカバー内側にあって、まず若干の、光線が集中した光点、フレアを投射し、光点と光点間は光照度が不足した暗エリアとなり、これら光点が発生した後では、ランプカバーに設置された屈折紋或いはフロスト処理により発生する拡散効果は相当に限られることにある。   The improvement effect that the light diffusion means in the above-mentioned prior art manifests is not ideal as expected, and there are problems such as multiple rays, multiple bright spots, uneven illumination, multiple shadows of the irradiated object, etc. Is still not effectively suppressed. As a result of the inventor's research on this, the main reason why the improvement effect of the known technology is not expected is that the inside of the lamp cover when a plurality of LED elements emit light, First, light spots and flares where light rays are concentrated are projected, and a dark area with insufficient light illuminance is formed between the light spots. After these light spots are generated, a refraction pattern or frost placed on the lamp cover is generated. The diffusion effect generated by the treatment is quite limited.

このことを鑑み、本発明は複数のＬＥＤ素子を使用したバルブに対して研究改良を行ない、ついに有効に多重光線照射の欠点を改善するＬＥＤバルブ及びそのランプカバーを提供するものである。   In view of this, the present invention provides an LED bulb and a lamp cover for the bulb that uses a plurality of LED elements, and finally effectively improves the disadvantages of multiple light irradiation.

本発明の目的は、ＬＥＤバルブ中の複数ＬＥＤ素子の発射する光線を均一に拡散させ且つ相互に融合させることにある。   An object of the present invention is to uniformly diffuse and fuse the light rays emitted from a plurality of LED elements in an LED bulb.

上述の目的のため、本発明の提供するＬＥＤバルブはランプヘッドとランプヘッドに取り付けられたランプカバーを包含し、該ランプヘッドのランプカバーに対応する接続端に複数のＬＥＤ素子が設けられ、ランプヘッド内に各ＬＥＤ素子を駆動して光線を発生させるために回路装置が設けられ、ランプヘッド末端に回路装置と外部バルブソケットを電気的に接続するためのコネクタが設けられている。   For the above purpose, the LED bulb provided by the present invention includes a lamp head and a lamp cover attached to the lamp head, and a plurality of LED elements are provided at connection ends corresponding to the lamp cover of the lamp head. A circuit device is provided in the head for driving each LED element to generate light, and a connector for electrically connecting the circuit device and an external bulb socket is provided at the end of the lamp head.

前述のランプカバーは複数のＬＥＤ素子を具えたランプヘッドに取り付けられる透光ケースを具え、該透光ケースの内側に各ＬＥＤ素子に対向するように導光柱が設けられ、各導光柱の根部の透光ケースに近い位置の外径は大きく、並びに少なくとも一側が隣り合う導光柱の根部と接続され、各導光柱が根部よりＬＥＤ素子に近い位置まで外径が漸減されつつ延伸されて錐体状を呈し、且つ該導光柱の端部にＬＥＤ素子の光線発生端を嵌め込む嵌め溝が設けられ、各ＬＥＤ素子の発生する光線が対応する導光柱を経て均一に拡散されて透光ケースに至り、外部に放射される。   The aforementioned lamp cover includes a translucent case attached to a lamp head including a plurality of LED elements, and a light guide column is provided inside the translucent case so as to face each LED element. The outer diameter at the position close to the translucent case is large, and at least one side is connected to the root portion of the adjacent light guide column, and each light guide column is stretched while the outer diameter is gradually reduced from the root portion to a position closer to the LED element to form a cone shape. In addition, a fitting groove for fitting the light generating end of the LED element is provided at the end of the light guide column, and the light generated by each LED element is uniformly diffused through the corresponding light guiding column to reach the light transmitting case. Radiated to the outside.

該導光柱の設置手段は、透光ケースと一体射出成形されるか、或いは先に各導光柱が一体射出成形されると共に、導光アセンブリの背部の各導光柱に対応する位置に凹部が形成され、該導光アセンブリが透光ケース内側に組み合わされ、各種の導光柱設置の技術手段はいずれも光線を導通させる効果を発生する。   The light guide column installation means may be integrally injection molded with the translucent case, or each light guide column is first integrally molded and a recess is formed at a position corresponding to each light guide column on the back of the light guide assembly. The light guide assembly is combined with the inner side of the translucent case, and any of various technical means for installing the light guide column generates an effect of conducting the light beam.

各導光柱と透光ケースが一体射出成形される時、各導光柱の根部位置に若干の光線導通補助用の拡径凸部或いは導光体が設けられ、光線を更に均一に拡散させる。   When each light guide column and the translucent case are integrally injection-molded, a small number of enlarged diameter convex portions or light guides for assisting light beam conduction are provided at the root position of each light guide column, and the light beam is diffused more uniformly.

従来の技術と比較すると、本発明のＬＥＤバルブ及びそのランプカバーは、複数のＬＥＤ素子の発生する光線を透光ケースに進入させる前に、導光柱により屈折、全反射させて均一に拡散させ、透光ケース内面に導入し、透光ケース（ランプカバー）内面で集中した光点、フレアを形成せず、これにより良好な照明効果を現出する。   Compared with the prior art, the LED bulb of the present invention and its lamp cover are refracted and totally reflected by the light guide column and uniformly diffused before the light rays generated by the plurality of LED elements enter the translucent case, It is introduced into the inner surface of the translucent case and does not form concentrated light spots and flares on the inner surface of the translucent case (lamp cover), thereby producing a good illumination effect.

図３及び図４は本発明の第１実施例の局部断面図及び立体分解図である。第１実施例のＬＥＤバルブはランプヘッド１０とランプヘッド１０に取り付けられるランプカバー２０を包含する。   3 and 4 are a local sectional view and a three-dimensional exploded view of the first embodiment of the present invention. The LED bulb of the first embodiment includes a lamp head 10 and a lamp cover 20 attached to the lamp head 10.

該ランプヘッド１０のランプカバー２０に対応する接続端に、複数のＬＥＤ素子１１が設置され、該ランプヘッド１０内に各ＬＥＤ素子１１を駆動して光線を発生させる回路装置１２が設けられ、該回路装置１２の底端に放熱フィンセット１３が設けられ、ランプヘッド１０の末端に回路装置１２と外部のバルブソケットを電気的に接続させるためのコネクタ１４が設けられ、ランプヘッド１０周囲に若干の放熱穿孔１５が設けられている。   A plurality of LED elements 11 are installed at a connection end corresponding to the lamp cover 20 of the lamp head 10, and a circuit device 12 that drives each LED element 11 to generate a light beam is provided in the lamp head 10. A radiating fin set 13 is provided at the bottom end of the circuit device 12, and a connector 14 for electrically connecting the circuit device 12 and an external bulb socket is provided at the end of the lamp head 10. A heat radiating hole 15 is provided.

前述ランプカバー２０の透光ケース２１内側の各ＬＥＤ素子１１に対応する位置に、透光ケース２１と一体に導光柱２２が延伸設置され、該導光柱２２の根部の透光ケース２１に近い位置の外径は大きく、並びに少なくとも一側が隣り合う導光柱２２の根部と接続され、各導光柱が根部より端部に外径を漸減しつつ延伸されて略錐体状を呈する（例えば円錐状、多角錐状とされ、図中では円錐状を代表として説明している）。この実施例の透光ケース２１は円弧形とされ、且つ各複数の導光柱２２と透光ケース２１は一体成形され、並びにそのうち若干の導光柱２２は環状に配列され、前述の環状に配列された導光柱２２の根部外周と透光ケース２１の接続位置は傾斜状に延伸されて導光体２３が形成され、各ＬＥＤ素子１１の発生する光線強度が減衰しない状況で、対応する導光柱２２を通して均一に拡散されて透光ケース２１に導入されて外部に放出され、こうして光線の均一分散の効果を達成する。   The light guide column 22 is extended and installed integrally with the light transmissive case 21 at a position corresponding to each LED element 11 inside the light transmissive case 21 of the lamp cover 20, and the position near the light transmissive case 21 at the root of the light guide column 22. The outer diameter of each of the light guide columns 22 is connected to the root portion of the adjacent light guide column 22, and each light guide column is elongated from the root portion to the end portion while gradually decreasing the outer diameter to have a substantially cone shape (for example, a cone shape, It has a polygonal pyramid shape, and the conical shape is described as a representative in the figure). The translucent case 21 of this embodiment has an arc shape, and the plurality of light guide columns 22 and the translucent case 21 are integrally formed, and some of the light guide columns 22 are arranged in an annular shape, and are arranged in the above-described annular shape. The connection position between the outer periphery of the light guide column 22 and the translucent case 21 is inclined to form a light guide 23, and the corresponding light guide column in a situation where the light intensity generated by each LED element 11 is not attenuated. The light is uniformly diffused through 22, introduced into the translucent case 21, and emitted to the outside, thus achieving the effect of uniform dispersion of light rays.

図５から図７は本発明の第２実施例を示す。第２実施例の第１実施例との違いは、各隣り合う導光柱２２の間が直接に接続されず、各導光柱２２の根部と透光ケース２１の接続位置に四周に向けて拡張された拡径凸部２４が設けられ、該拡径凸部２４の少なくとも１辺が延伸されて円弧凸状の導光体２３が設けられ、該円弧凸状の導光体２３は隣り合う導光柱２２の拡径凸部２４と接続される。   5 to 7 show a second embodiment of the present invention. The difference between the second embodiment and the first embodiment is that the adjacent light guide columns 22 are not directly connected to each other, and are extended to the connection position between the root of each light guide column 22 and the translucent case 21 in four directions. The diameter-expanded convex part 24 is provided, and at least one side of the diameter-expanded convex part 24 is extended to provide an arc-shaped light guide 23, and the arc-shaped light guide 23 is adjacent to the light guide column. 22 is connected to the enlarged-diameter convex portion 24.

前述の透光ケース２１の実施時には、その透光態様は材質が透明、材質が半透明、或いは材質が透明で表面にフロスト処理がなされたものを包含し、該透光ケース２１の底端周囲に係合フランジ２５が設けられる。ランプヘッド１０には該係合フランジ２５に対応する係合溝１６が設けられて透光ケース２１の係止に供され、該係合フランジ２５に少なくとも一つの切欠き２６が設けられ、ランプヘッド１０に該切欠き２６に対応してランプカバー２０のランプヘッド１０に対する回転を防止するためのストッパ１７が設けられ、これによりランプヘッド１０とランプカバー２０が速やかに組み立てられる。   When the above-described translucent case 21 is implemented, the translucent mode includes a transparent material, a translucent material, or a transparent material that has been subjected to a frost treatment on the surface. An engagement flange 25 is provided on the front side. The lamp head 10 is provided with an engagement groove 16 corresponding to the engagement flange 25 to be used for locking the translucent case 21, and the engagement flange 25 is provided with at least one notch 26. 10 is provided with a stopper 17 for preventing the rotation of the lamp cover 20 relative to the lamp head 10 corresponding to the notch 26, whereby the lamp head 10 and the lamp cover 20 are assembled quickly.

このほか、前述の導光柱２２の端部にＬＥＤ素子１１の光線発生端を嵌め込む嵌め溝２７が設けられ、該嵌め溝２７内にＬＥＤ素子１１の光線発生端に対応する円弧凸面２８が設けられ、該円弧凸面２８は嵌め溝２７内に一体成形されるか、嵌め溝２７の溝底に挿入されたレンズで構成される。   In addition, a fitting groove 27 for fitting the light generating end of the LED element 11 is provided at the end of the light guide column 22, and an arc convex surface 28 corresponding to the light generating end of the LED element 11 is provided in the fitting groove 27. The arc-shaped convex surface 28 is formed of a lens that is integrally formed in the fitting groove 27 or inserted into the groove bottom of the fitting groove 27.

この実施例の複数の導光柱２２は放射状の配列態様を呈し、そのうち一つの導光柱２２は透光ケース２１の内面の中央に位置し、その他の導光柱２２は中央位置の導光柱２２を囲むように配置される。   In this embodiment, the plurality of light guide columns 22 are arranged in a radial pattern, and one of the light guide columns 22 is located at the center of the inner surface of the translucent case 21, and the other light guide columns 22 surround the light guide columns 22 at the center position. Are arranged as follows.

各ＬＥＤ素子１１が光線を発生する時、光線は該円弧凸面２８により屈折し拡散光線を形成し、並びに光線が導光柱２２内に直接入射し、光線の全反射、屈折の原理により、光線が導光柱２２、拡径凸部２４、円弧凸状の導光体２３を経て均一に拡散されて透光ケース２１に導入された後、外部に放射される。このように、ＬＥＤ素子１１の発生する光線が透光ケース２１に進入する前に既に均一に拡散される。   When each LED element 11 generates a light beam, the light beam is refracted by the arc convex surface 28 to form a diffused light beam, and the light beam is directly incident on the light guide column 22, and the light beam is reflected by the principle of total reflection and refraction of the light beam. After being uniformly diffused through the light guide column 22, the diameter-expanded convex portion 24, and the arc-shaped light guide 23 and introduced into the translucent case 21, it is emitted to the outside. Thus, the light rays generated by the LED elements 11 are already uniformly diffused before entering the translucent case 21.

図８及び図９は本発明の第３実施例を示す。この実施例と実施例１との違いは、複数の導光柱２２が一体射出成形されて導光アセンブリ３０が形成された後、さらに、導光アセンブリ３０が透光ケース２１内側に取り付けられることである。該導光アセンブリ３０の背部の、各導光柱２２に対応する位置には凹部２９が形成されていて、各導光柱２２が中空状とされ、各ＬＥＤ素子１１の発生する光線強度が減衰しない状況で、対応する導光柱２２を通り均一に拡散されて透光ケース２１に導入され、さらに外部に射出される。こうして光線を均一に分散させる効果を達成する。前述の第１、２、３実施例のランプカバー２０の透光ケース２１造形及び導光柱２２の配列方式は、円弧形態様の透光ケース２１、放射状配列の導光柱２２で説明されているが、実際の実施時には必要により透光ケース２１の造形態様、導光柱２２の配列方式を変更可能である。   8 and 9 show a third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the light guide assembly 30 is attached to the inner side of the translucent case 21 after the light guide pillars 22 are integrally injection molded to form the light guide assembly 30. is there. The concave portion 29 is formed at a position corresponding to each light guide column 22 on the back portion of the light guide assembly 30, and each light guide column 22 is hollow, so that the light intensity generated by each LED element 11 is not attenuated. Thus, the light is uniformly diffused through the corresponding light guide column 22, introduced into the translucent case 21, and further emitted to the outside. Thus, the effect of uniformly dispersing the light beam is achieved. The formation of the translucent case 21 of the lamp cover 20 and the arrangement method of the light guide columns 22 in the first, second, and third embodiments described above are explained by the translucent case 21 having an arc shape and the light guide columns 22 having a radial arrangement. However, at the time of actual implementation, the shaping mode of the translucent case 21 and the arrangement method of the light guide columns 22 can be changed as necessary.

例えば、図１０の本発明第４実施例のランプカバー内面表示図に示されるように、この実施例のランプカバーの透光ケース２１は略矩形態様を呈し、導光柱２２は矩形アレイ方式で配列されている。また、図１１の本発明第５実施例のランプカバー内面表示図に示されるように、この実施例のランプカバーの透光ケース２１は略円弧状の長尺状態様とされ、導光柱２２は長尺状の方式で配列されている。このほか、この実施例はさらに図中の点線で描かれる放熱シートと導電端子が組み合わされて蛍光灯管の造形態様を呈する。   For example, as shown in the lamp cover inner surface display diagram of the fourth embodiment of the present invention in FIG. 10, the translucent case 21 of the lamp cover of this embodiment has a substantially rectangular shape, and the light guide columns 22 are arranged in a rectangular array system. Has been. In addition, as shown in the lamp cover inner surface display diagram of the fifth embodiment of the present invention in FIG. 11, the translucent case 21 of the lamp cover of this embodiment is in a substantially arc-like long state, and the light guide column 22 is They are arranged in a long form. In addition, in this embodiment, a heat-dissipating sheet drawn with a dotted line in the drawing and a conductive terminal are combined to form a fluorescent lamp tube.

図１２は本発明の第６実施例の正面視外観図である。第５実施例の第１実施例との違いは、該ランプヘッド１０の実施長さが比較的長く、ＬＥＤバルブは深さが比較的深い取付け環境中に取り付けられ、採用するコネクタ１４が前述の一般に見られるものとは異なり、差し込み形のコネクタ１４とされ、ソケット型の外部ランプシートと嵌挿接合される。   FIG. 12 is a front view of the sixth embodiment of the present invention. The fifth embodiment differs from the first embodiment in that the lamp head 10 has a relatively long working length, the LED bulb is mounted in a mounting environment having a relatively deep depth, and the connector 14 employed is the above-described one. Unlike what is generally found, the connector 14 is a plug-in connector 14 and is fitted and joined to a socket-type external lamp sheet.

総合すると、本発明の各実施例のＬＥＤバルブは、複数のＬＥＤ素子の発生する光線を透光ケースに進入させる前に、導光柱、拡径凸部、円弧凸状の導光体の屈折、全反射作用により均一に拡散させて透光ケース内面に導入し、比較的良好な照明効果を現出する。   To sum up, the LED bulb of each embodiment of the present invention has a light guide column, an enlarged convex portion, a refracted circular arc light guide, before light beams generated by a plurality of LED elements enter the translucent case, It is diffused uniformly by the total reflection action and introduced into the inner surface of the translucent case, and a relatively good lighting effect appears.
