Description

本発明は、発光ダイオードの点灯もしくは点滅により３６０度の全方向に警報を発する全方向警報灯に関するものである。   The present invention relates to an omnidirectional warning lamp that issues an alarm in all directions of 360 degrees by turning on or blinking a light emitting diode.

本願出願人外１名により全方向踏切警報灯が既に開発され（特許文献１）、実用されている。また、多面発光体を有する全方位踏切警報灯が特許文献２により提案されている。   An omnidirectional railroad crossing warning light has already been developed and put into practical use by one outside the applicant of the present application (Patent Document 1). Patent Document 2 proposes an omnidirectional railroad crossing warning light having a multi-surface light emitter.

特許第４３１３７００号公報Japanese Patent No. 4313700 特開２０１０−１７９６６４号公報JP 2010-179664 A

しかしながら、特許文献１に記載の発明は、発光ダイオード基板が４枚十字状に配置されているので、コスト高であることが問題であった。   However, the invention described in Patent Document 1 has a problem of high cost because four light emitting diode substrates are arranged in a cross shape.

また、特許文献２に記載の発明は、多面立体構造の基板取付枠にＬＥＤ実装基板を取り付けるものであり、やはりコスト高となるものである。   In addition, the invention described in Patent Document 2 attaches an LED mounting board to a board mounting frame having a multi-faceted three-dimensional structure, which also increases the cost.

（発明の目的）
本発明の目的は、コストダウンを図ることができる全方向警報灯を提供することである。 (Object of invention)
The objective of this invention is providing the omnidirectional warning light which can aim at cost reduction.

上記目的を達成するために、本発明の全方向警報灯は、３枚の発光ダイオード基板を有し、前記各発光ダイオード基板の両面に定められた発光領域には多数の発光ダイオードが取り付けられており、前記発光領域の輪郭を表す図形が楕円形をなし、前記３枚の発光ダイオード基板が、前記半楕円形の短軸が前記各発光ダイオード基板の一辺である合せ目辺に一致し、かつ、前記合せ目辺のそれぞれが垂直になって合わさるように、１２０度間隔でＹ字状に固定されていることを特徴とするものである。 In order to achieve the above object, the omnidirectional warning lamp of the present invention has three light emitting diode substrates, and a plurality of light emitting diodes are attached to the light emitting areas defined on both surfaces of each of the light emitting diode substrates. cage, wherein no graphic representing the contour of the light emitting region elliptical, the three light emitting diodes substrate, the minor axis of the semi-elliptical matches the the seam edge is one side of each light-emitting diode substrate, and , And are fixed in a Y shape at intervals of 120 degrees so that the respective sides of the joints are aligned vertically.

本発明によれば、３６０度の範囲でどの方向からも円に近いイメージで発光を視認させることができると同時に、全方向警報灯のコストダウンを図ることができる。 According to the present invention , light emission can be visually recognized in an image close to a circle from any direction within a range of 360 degrees, and at the same time, the cost of an omnidirectional warning lamp can be reduced.

本発明を実施するための形態は、後述する実施例に記載の通りである。   The form for implementing this invention is as the description in the Example mentioned later.

図１は本発明の一実施例である全方向警報灯の発光ダイオード基板（以下ＬＥＤ基板という）を示す平面図、図２は同じく斜視図、図３は発光ダイオードの発光領域を示す図である。   FIG. 1 is a plan view showing a light emitting diode substrate (hereinafter referred to as an LED substrate) of an omnidirectional warning lamp according to an embodiment of the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is a view showing a light emitting region of the light emitting diode. .

四角形のＬＥＤ基板１はメイン１枚とサブ２枚の合計３枚あり、１２０度間隔でＹ字状にかつ垂直に配置されている。３枚のＬＥＤ基板１の両面には発光領域２が定められている。各発光領域２に多数の発光ダイオード３が取り付けられている。発光領域２の輪郭を表す図形は半楕円形となっている。半楕円形の発光領域２は、半楕円形の短軸がＬＥＤ基板１の合せ目となる合せ目辺１ａに一致するように定められている。図３（ａ）に示されるように、ＬＥＤ基板１を正面から見ると、多数の発光ダイオード３の発光形状は半楕円である。しかし、図２に示されるように、３枚のうちのいずれかのＬＥＤ基板１の延長上、即ち図１のＢ方向からから見ると、図３（ｂ）に示されるように真円に見える。また、図１のＡ方向から見ると、図３（ｃ）に示されるように最も歪な円形に見える。歪な円形であっても、円形と認識することができる。したがって、３６０度の範囲でどの方向からも円に近いイメージで発光を視認させることができる。   The square LED substrate 1 has a total of three, one main and two sub, and is arranged in a Y-shape and vertically at intervals of 120 degrees. Light emitting areas 2 are defined on both surfaces of the three LED substrates 1. A large number of light emitting diodes 3 are attached to each light emitting region 2. The figure representing the outline of the light emitting region 2 is a semi-elliptical shape. The semi-elliptical light emitting region 2 is defined so that the semi-elliptical minor axis coincides with a joint side 1 a that is a joint of the LED substrate 1. As shown in FIG. 3A, when the LED substrate 1 is viewed from the front, the light emission shape of the many light emitting diodes 3 is a semi-ellipse. However, as shown in FIG. 2, when viewed from the extension of any one of the three LED substrates 1, that is, from the direction B in FIG. 1, it looks like a perfect circle as shown in FIG. 3B. . Further, when viewed from the direction A in FIG. 1, it looks like the most distorted circle as shown in FIG. Even a distorted circle can be recognized as a circle. Therefore, it is possible to visually recognize light emission in an image close to a circle from any direction within a range of 360 degrees.

ＬＥＤ基板１への電源供給は、例えば図４に示されるように、メインＬＥＤ基板１Ａには直接的に行われ、サブＬＥＤ基板１Ｂ、１ＣにはメインＬＥＤ基板１Ａを介して行われる。   For example, as shown in FIG. 4, the power supply to the LED substrate 1 is performed directly on the main LED substrate 1A, and is performed on the sub LED substrates 1B and 1C via the main LED substrate 1A.

図５は本発明の一実施例である全方向警報灯の組立状態を示す正面図及び底面図である。   FIG. 5 is a front view and a bottom view showing an assembled state of an omnidirectional warning lamp according to an embodiment of the present invention.

図５において、灯体４は、金属製などのひさし５、ひさし５に固定された透明樹脂製で円筒形のカバー６、カバー６内に配置されたＬＥＤ基板１、金属製などの背板７、及び外線端子を内蔵する回転接手８から主として構成されている。カバー６は、ひさし５に固定された垂直下方に延びる支柱９及び底板１０によってひさし５に固定される。発光ダイオード３としては、視野角の広いものが好ましい。ＬＥＤ基板１の３枚は、合せ目辺１ａが灯体４の中心位置で垂直になって合わさるように、１２０度間隔でＹ字状に配置される。３枚のＬＥＤ基板１はひさし５及び底板１０に取り付けられた取付片（不図示）に固定ねじ（不図示）などにより着脱可能に固定される。   In FIG. 5, a lamp body 4 includes an eave 5 made of metal, a transparent cover 6 made of a transparent resin fixed to the eaves 5, an LED substrate 1 disposed in the cover 6, and a back plate 7 made of metal, etc. , And a rotary joint 8 incorporating an external terminal. The cover 6 is fixed to the eaves 5 by vertically supporting columns 9 and a bottom plate 10 fixed to the eaves 5. The light emitting diode 3 preferably has a wide viewing angle. The three LED substrates 1 are arranged in a Y shape at intervals of 120 degrees so that the joint edge 1a is vertically aligned at the center position of the lamp body 4. The three LED substrates 1 are detachably fixed to mounting pieces (not shown) attached to the eaves 5 and the bottom plate 10 by fixing screws (not shown).

カバー６としては例えば非拡散性の赤色アクリルカバーが用いられる。背板７はＬ字形のもので、カバー６の周囲に、ＬＥＤ基板１と同一平面上に位置するようにひさし５に固定される。背板７はＬＥＤ基板１の周囲の外光を遮断し、その発光を見やすくするためのものである。   For example, a non-diffusible red acrylic cover is used as the cover 6. The back plate 7 is L-shaped, and is fixed to the eaves 5 so as to be positioned on the same plane as the LED substrate 1 around the cover 6. The back plate 7 is used to block outside light around the LED substrate 1 and make it easy to see the emitted light.

ＬＥＤ基板１はひさし５に設けられた取付片に固定ねじにより着脱可能に固定されているので（下端部でも底板１０に着脱可能に固定されていても良い）、メインＬＥＤ基板１Ａ又はサブＬＥＤ基板１Ｂ、１Ｃの交換や修理が容易である。   Since the LED board 1 is detachably fixed to a mounting piece provided on the eaves 5 by a fixing screw (may be detachably fixed to the bottom plate 10 at the lower end portion), the main LED board 1A or the sub LED board Replacement and repair of 1B and 1C are easy.

本実施例では、３枚のＬＥＤ基板１を１２０度間隔でＹ字状に配置したので、特許文献１のものよりコストダウすることができる。また、発光領域２の輪郭を表す図形を半楕円形としたので、どの方向からでも円に近いイメージで発光を視認させることができる。   In this embodiment, since the three LED substrates 1 are arranged in a Y shape at intervals of 120 degrees, the cost can be reduced from that of Patent Document 1. Moreover, since the figure showing the outline of the light emitting region 2 is a semi-elliptical shape, the light emission can be visually recognized in an image close to a circle from any direction.

本発明の全方向警報灯は、踏切警報灯として好適なものであるが、踏切警報以外の鉄道用の警報灯、道路用、車両用、建物用などの警報灯としても有用なものである。   The omnidirectional warning light of the present invention is suitable as a railroad crossing warning light, but is also useful as a warning light for railways, roads, vehicles, buildings, etc. other than a railroad crossing warning.
