Description

本考案は、発光ダイオード（ＬＥＤ）を具備した種々の照明器具において、発光源の光を広範囲に外部に照射することが可能な柱状反射レンズに関する。  The present invention relates to a columnar reflecting lens capable of irradiating light from a light source to the outside in a wide range in various lighting fixtures including light emitting diodes (LEDs).

１Ｗ以上の高出力ＬＥＤを用いた電球型照明器具や直線状に配列した照明器具が開発されている。しかしながら、これらのＬＥＤ照明器具では、ＬＥＤ素子や回路素子の保護のため、放熱板が不可欠となっている。従来のフィラメント型電球では、フィラメントは電球の中央部に突き出して取り付けられるため、電球面全域から光が照射されているのに対して、ＬＥＤを用いた場合には、放熱の必要から光源を電球の付け根の位置に取り付けざるを得ないため、光が十分に拡散しにくい欠点があった。  Bulb-type lighting fixtures using high-power LEDs of 1 W or more and lighting fixtures arranged in a straight line have been developed. However, in these LED lighting fixtures, a heat sink is indispensable for protection of LED elements and circuit elements. In the conventional filament type light bulb, the filament is attached to the central portion of the light bulb so that light is irradiated from the entire surface of the light bulb. Since it has to be attached to the position of the base of the light, there is a drawback that light is not sufficiently diffused.

本考案は、ＬＥＤからの発光を集光し、光源から離れた位置で拡散する柱状反射レンズにより前記欠点を除く照明器具を提供することにある。  An object of the present invention is to provide a luminaire that eliminates the above-mentioned drawbacks by using a columnar reflection lens that collects light emitted from an LED and diffuses it at a position away from the light source.

課題を解決すための手段Means to solve the problem

上記問題を解決するために本考案の柱状反射レンズは、発光部から放射された光を集光し、側面方向に反射するための反射面が複数縦列方向に内設されていることを特徴とする。なお、このレンズに類し、上記の先行技術文献がある。  In order to solve the above problems, the columnar reflecting lens of the present invention is characterized in that a plurality of reflecting surfaces for concentrating the light emitted from the light emitting part and reflecting the light in the side surface direction are provided in a plurality of column directions. To do. In addition, there exists said prior art document similar to this lens.

考案の効果Effect of device

上述の様に、柱状反射レンズを適用することにより、放熱板に取り付けられたＬＥＤの光を、光源から離れた位置で照射することが可能な照明器具を提供することができる。さらに、この反射面の形状および段数を光源の強度などによって選択することにより、一般照明から装飾的照明まで多様な照明器具とすることができる。  As described above, by applying the columnar reflection lens, it is possible to provide a lighting fixture capable of irradiating the light of the LED attached to the heat sink at a position away from the light source. Furthermore, by selecting the shape and the number of steps of the reflecting surface according to the intensity of the light source and the like, it is possible to make various lighting fixtures from general lighting to decorative lighting.

以下、本考案における柱状反射レンズを、実施の形態に基づき説明する。図１及び図２に示す柱状反射レンズ１は、レンズ底面からの入射光（図中矢線）をレンズ内部に設けられた反射面２により側面方向に照射することを特徴とする。即ち、レンズ底面から入射された光は、柱状レンズにそって伝播し、柱状体に内設された面２により反射され、レンズの側面方向に照射される。  Hereinafter, a columnar reflection lens according to the present invention will be described based on embodiments. The columnar reflection lens 1 shown in FIGS. 1 and 2 is characterized in that incident light (arrow line in the figure) from the lens bottom surface is irradiated in the side surface direction by a reflection surface 2 provided inside the lens. That is, light incident from the bottom surface of the lens propagates along the columnar lens, is reflected by the surface 2 provided in the columnar body, and is irradiated in the side surface direction of the lens.

反射面２は複数設けられ、１段目で横方向に反射するとともに、１部通過した光が２段目で反射、さらに３段目で反射することで、底面から入射された全光は徐々に側面方向と前方に照射される。なお、図では３個の反射面を示してあるが、この反射面の数及び間隔は光源の光強度や用途に応じて決定される。  A plurality of reflecting surfaces 2 are provided, and the light reflected by the first stage is reflected in the second stage and further reflected by the third stage, so that all the light incident from the bottom is gradually reflected. Irradiated sideways and forward. In the figure, three reflecting surfaces are shown, but the number and interval of the reflecting surfaces are determined according to the light intensity and application of the light source.

また反射面２は円錐形状，角錐形状，指数関数形状、Ｖ字形状などとすることができる．  The reflecting surface 2 can be conical, pyramidal, exponential, V-shaped, or the like.

レンズの断面形状は、用途に応じて円形、多角形とすることで、それぞれに特色ある反射光を得ることができる。また、軸心方向に関しては、図１に示すように円柱状および図２のような円錐状とすることができる。  The cross-sectional shape of the lens is circular or polygonal depending on the application, so that it is possible to obtain characteristic reflected light in each. In addition, the axial direction can be cylindrical as shown in FIG. 1 and conical as shown in FIG.

図３は、本考案の柱状反射レンズを、放熱を要する高出力ＬＥＤを用いた照明器具に応用した円柱型反射レンズＬＥＤ照明器具の例である。  FIG. 3 is an example of a cylindrical reflection lens LED lighting fixture in which the columnar reflection lens of the present invention is applied to a lighting fixture using a high-power LED that requires heat dissipation.

図３において、ＬＥＤ３は柱状レンズ１下部の放熱板４に取り付けられ、柱状レンズ１の底面からレンズに光を入射する。図中６はレンズを保持するホルダーであり、熱によるレンズの劣化を避けたい材質においては、放熱板の熱を遮断するようにする。底面から入射された光は、前項図１及び図２にて述べられた原理により、ＬＥＤの光源より離れた位置で入射光を側面方向に照射することができる。以上のとおり、光源の位置を移動する効果を得ることができるため、従来のフィラメントを用いた電球と同様な拡散光が得られる。  In FIG. 3, the LED 3 is attached to the heat radiating plate 4 below the columnar lens 1, and light enters the lens from the bottom surface of the columnar lens 1. In the figure, reference numeral 6 denotes a holder for holding the lens, and in a material where it is desired to avoid lens deterioration due to heat, the heat of the heat sink is cut off. The light incident from the bottom surface can be irradiated in the lateral direction at a position away from the light source of the LED according to the principle described in FIGS. As described above, since the effect of moving the position of the light source can be obtained, diffused light similar to a conventional light bulb using a filament can be obtained.

上記柱状反射レンズ１の材質としては、樹脂、ガラス、水晶など透光性のあるものが適当である。また、柱状レンズに色を施すことにより、多様な用途に適合する照明器具とすることができる。即ち、従来の電球や電球型ＬＥＤ照明のように、球殻ガラスを必要とすることなく、製造コストを大幅に減額することができる。  As a material of the columnar reflection lens 1, a light-transmitting material such as resin, glass, crystal, or the like is appropriate. Moreover, it can be set as the lighting fixture suitable for various uses by coloring a columnar lens. That is, the manufacturing cost can be greatly reduced without the need for a spherical shell glass unlike conventional light bulbs and light bulb type LED lighting.

図４は、図３の円柱型反射レンズＬＥＤ照明器具８にカバー９を具備したものである、このカバー９は、樹脂、ガラスなどにより成り、形状も球形、円筒状、立方形状とすることができる。また、カバーに蛍光物質を塗布することで、光の色調を変えることができる。  FIG. 4 shows the cylindrical reflective lens LED lighting fixture 8 of FIG. 3 provided with a cover 9. The cover 9 is made of resin, glass or the like, and the shape thereof may be spherical, cylindrical or cubic. it can. Moreover, the color tone of light can be changed by applying a fluorescent material to the cover.

図５は、図２の円錐型反射レンズを応用したＬＥＤ照明器具の例である。柱状反射レンズを円錐形状とすることで、ＬＥＤを複数用いた高照度照明器具に適用できる。
図５の例では、電源部に既存の白熱電球に適合する口金１０を具備することにより白熱電球に代替でき、消費電力を削減することができる。FIG. 5 is an example of an LED lighting apparatus to which the conical reflection lens of FIG. 2 is applied. By making the columnar reflection lens into a conical shape, it can be applied to a high-illuminance lighting apparatus using a plurality of LEDs.
In the example of FIG. 5, by providing the base 10 suitable for an existing incandescent bulb in the power supply unit, it can be replaced with an incandescent bulb and power consumption can be reduced.

なお、本考案の柱状反射レンズは、当然のことであるが、円形及び直線状に多数配列されたＬＥＤに対しても適用できる。  The columnar reflection lens of the present invention is naturally applicable to a large number of LEDs arranged in a circle and a straight line.
