Description
本考案は、発光ダイオード（以下、「ＬＥＤ」という。）を照明用光源とする電球型ＬＥＤ照明器具に用いる反射鏡及びそれを用いた反射鏡付き電球型ＬＥＤ照明器具に関する。具体的には、ＬＥＤ照明の指向性を改善して、従来の白色電球のように室内を広範囲に照らすことのできる電球型ＬＥＤ照明器具に用いる反射鏡及びそれを用いた反射鏡付き電球型ＬＥＤ照明器具に関する。 The present invention relates to a reflector used in a bulb-type LED lighting fixture using a light-emitting diode (hereinafter referred to as “LED”) as an illumination light source, and a bulb-type LED lighting fixture with a reflector using the same. Specifically, a reflector used in a bulb-type LED lighting apparatus that improves the directivity of LED lighting and can illuminate a room over a wide area like a conventional white bulb, and a bulb-type LED with a reflector using the reflector It relates to lighting equipment.
近年ＬＥＤを照明用光源とする照明器具の開発が行われており、地球温暖化対策の観点からより消費電力の少ない電球型ＬＥＤ照明器具を白色電球に代替することが提案されている。白色電球は前方のみならず側方や後方まで、口金で影となる領域を除き、ほぼ全方位に光を取り出すことができる。一方、ＬＥＤを光源とした電球型ＬＥＤ照明器具は、発光部からの出射される光の指向性が強いためその照射角が制限され、従来の白色電球照明のように広範囲に照らすことができない。拡散カバーを使用した場合でも、最大で210度と狭い。このため、指向性を改善したＬＥＤ照明器具が提案されている（特許文献１〜３）。特許文献１は、発光モジュールを載せる第１基台に逆錐台状の第２基台を設け、第２基台の側面を反射鏡として出射光の指向性を改善する提案である。特許文献２は、発光モジュールを載せる基台の中央部に光出射方向に突出した突出部を有する反射体を備え、これにより出射光の指向性を改善する提案である。特許文献３は、ＬＥＤ光源部をテーパー状にして出射光の指向性を改善する提案である。 In recent years, lighting fixtures using LEDs as illumination light sources have been developed, and it has been proposed to replace light bulb-type LED lighting fixtures with lower power consumption with white light bulbs from the viewpoint of global warming countermeasures. The white light bulb can extract light not only in the front but also in the side and rear, except for the area shaded by the base, in almost all directions. On the other hand, a bulb-type LED lighting fixture using an LED as a light source has a strong directivity of light emitted from a light-emitting unit, and therefore, its irradiation angle is limited, and cannot be illuminated in a wide range like conventional white bulb lighting. Even when a diffusion cover is used, the maximum is 210 degrees. For this reason, the LED lighting fixture which improved directivity is proposed (patent documents 1-3). Patent Document 1 is a proposal for improving the directivity of emitted light by providing a second base having an inverted frustum shape on a first base on which a light emitting module is mounted, and using a side surface of the second base as a reflecting mirror. Patent Document 2 is a proposal for improving the directivity of emitted light by providing a reflector having a protruding portion protruding in the light emitting direction at the center of a base on which the light emitting module is placed. Patent Document 3 is a proposal for improving the directivity of emitted light by making the LED light source portion tapered.
上述した電球型ＬＥＤ照明の指向性を改善する方法は、いずれも照明器具そのものの構造を変更して新たに創りだすものであり、既存構造のＬＥＤ照明器具の指向性を改善するものでなく、装置コストが高くなるという問題がある。 The above-described methods for improving the directivity of the bulb-type LED lighting are all created by changing the structure of the lighting fixture itself, and do not improve the directivity of the existing LED lighting fixture, There is a problem that the apparatus cost becomes high.
本考案は、上記課題を解決し、取り付けが簡単で、従来の白色電球のように室内を広範囲に照らすことのできる電球型ＬＥＤ照明器具に用いる反射鏡及びそれを取り付けた電球型ＬＥＤ照明器具を提供することを目的とする。 The present invention solves the above-described problems, and provides a reflector for use in a bulb-type LED lighting fixture that can illuminate a room in a wide range like a conventional white bulb, and a bulb-type LED lighting fixture to which the reflector is attached. The purpose is to provide.

This is because the directivity of the emitted light of the LED lighting fixture having the existing structure can be easily improved by using the inverted frustoconical reflecting mirror.
＜２＞基板上に複数のＬＥＤ光源を配置した光源部を有する電球型ＬＥＤ照明の前記基板上に取り付け可能な周面を有する環状の反射鏡であって、前記反射鏡は外周側面に反射面を備え、前記外周側面の形状が彎曲した周曲面であることを特徴とするＬＥＤ照明光源部に取り付け可能な反射鏡である。外周側面の形状を彎曲した周曲面とすることで、フラットな円錐側面に比べて出射光の指向性をさらに改善できるからである。 <2> An annular reflecting mirror having a peripheral surface that can be mounted on the substrate of a light bulb-type LED illumination having a light source unit in which a plurality of LED light sources are arranged on the substrate, and the reflecting mirror is a reflecting surface on an outer peripheral side surface And a reflector that can be attached to an LED illumination light source section, wherein the shape of the outer peripheral side surface is a curved curved surface. This is because the directivity of the emitted light can be further improved by making the peripheral curved surface the curved shape of the outer peripheral side surface as compared with the flat conical side surface.
＜３＞前記反射鏡の外周側面に備わる反射面が銀反射層を内部に有する多層フィルムにより形成されたものであることを特徴とする前記＜１＞または＜２＞に記載したＬＥＤ照明光源部に取り付け可能な反射鏡である。反射面を可撓性があり着脱可能なフィルムとすることで取付が容易となるからである。 <3> The LED illumination light source unit according to <1> or <2>, wherein a reflection surface provided on an outer peripheral side surface of the reflection mirror is formed of a multilayer film having a silver reflection layer therein. It can be attached to the reflector. This is because attachment is facilitated by making the reflective surface flexible and detachable.

This is because the present invention can be realized by attaching the reflecting mirror of the present invention to a bulb-type LED lighting fixture.
本考案の反射鏡を電球型ＬＥＤ照明器具の光源部に取り付けることにより、従来の白色電球のように室内を広範囲に照らすことのできる電球型ＬＥＤ照明器具を提供できる。 By attaching the reflecting mirror of the present invention to the light source part of a light bulb type LED lighting device, a light bulb type LED lighting device capable of illuminating a room widely like a conventional white light bulb can be provided.
以下、図面を参照しながら、本考案の実施の態様である電球型ＬＥＤ照明の前記基板上に取り付け可能な周面を有する環状の反射鏡について説明する。 Hereinafter, an annular reflecting mirror having a peripheral surface that can be mounted on the substrate of a bulb-type LED illumination according to an embodiment of the present invention will be described with reference to the drawings.
図１は、本考案の反射鏡をＬＥＤ光源部に取り付けた電球型ＬＥＤ照明器具の説明図であり、図２は、本考案の反射鏡を取り付けるＬＥＤ光源部のＬＥＤの配列一例を示した説明図である。 FIG. 1 is an explanatory diagram of a light bulb type LED lighting fixture in which a reflector of the present invention is attached to an LED light source unit, and FIG. 2 is an explanation showing an example of an LED array of the LED light source unit to which the reflector of the present invention is attached. FIG.
図１に示すように、電球型ＬＥＤ照明器具１は、口金１１、筒状基体１２、光源基板１３、反射鏡１４、拡散カバー１５、ＬＥＤ１６から構成されている。反射鏡１４は光源基板１３に設けられた嵌合用ツメ固定穴（図２）を介して取り付ける。 As shown in FIG. 1, the bulb-type LED lighting device 1 includes a base 11, a cylindrical base 12, a light source substrate 13, a reflecting mirror 14, a diffusion cover 15, and an LED 16. The reflecting mirror 14 is attached through a fitting claw fixing hole (FIG. 2) provided in the light source substrate 13.
図２に示すように、光源基板１３の上表面に設けられた光源部２は、同心円状に配置されたＬＥＤ２１と本考案の反射鏡を嵌合させるための嵌合用ツメ固定穴２２から構成されている。本考案の反射鏡は、反射鏡下部に設けられた嵌合用ツメ（図３）と嵌合用ツメ固定穴２２により固定される。このように、反射鏡をＬＥＤ照明器具と一体としないで、反射鏡が脱着できることにより、ＬＥＤ照明器具を設置する場所ごとに照射範囲を自由に調整することができる。 As shown in FIG. 2, the light source section 2 provided on the upper surface of the light source substrate 13 is configured by a fitting claw fixing hole 22 for fitting the LED 21 arranged concentrically with the reflecting mirror of the present invention. ing. The reflector of the present invention is fixed by a fitting claw (FIG. 3) and a fitting claw fixing hole 22 provided at the lower part of the reflecting mirror. As described above, since the reflecting mirror can be attached and detached without integrating the reflecting mirror with the LED lighting fixture, the irradiation range can be freely adjusted for each place where the LED lighting fixture is installed.
図３に示すように、本考案の反射鏡の形状は、周面３１を有する環状である。上下の開放面は、上部開放面が下部開放面に比べて広い。また、下部開放面周縁３２には嵌合用ツメ３３が設けられている。なお、反射面は外周側面に設けられている。この形状により、下部開放面内に含まれるＬＥＤからは正面前方に光が出射され、下部開放面外に含まれるＬＥＤから出射された光は反射面の形状に則して反射されて側面または後方面に出射される。これにより、従来の白色電球のように室内を広範囲に照らすことができる。 As shown in FIG. 3, the shape of the reflecting mirror of the present invention is an annular shape having a peripheral surface 31. The upper and lower open surfaces have a wider upper open surface than the lower open surface. Further, a fitting claw 33 is provided on the lower open surface peripheral edge 32. The reflective surface is provided on the outer peripheral side surface. With this shape, light is emitted forward from the LED included in the lower open surface, and light emitted from the LED included outside the lower open surface is reflected according to the shape of the reflective surface to be side or rear. It is emitted in the direction. As a result, the room can be illuminated over a wide area like a conventional white light bulb.
図４Ａは、反射鏡の外周側面４１が円錐側面である場合の本発明の反射鏡を示す側面図であり、図４Ｂは、その場合のＬＥＤ出射光の反射状態を模式的に示したものである。また、図５Ａは、反射鏡の外周側面５１が彎曲した周曲面である場合の本発明の反射鏡を示す側面図であり、図５Ｂは、その場合のＬＥＤ出射光の反射状態を模式的に示したものである。彎曲した周曲面の方が反射光は広がる。なお、本考案の外周側面の形状は、図４Ａ、図４Ｂに限定されるものでなく、例えばエンボス加工された形状であってもよい。 FIG. 4A is a side view showing the reflecting mirror of the present invention when the outer peripheral side surface 41 of the reflecting mirror is a conical side surface, and FIG. 4B schematically shows the reflected state of LED emitted light in that case. is there. FIG. 5A is a side view showing the reflecting mirror of the present invention when the outer peripheral side surface 51 of the reflecting mirror is a curved surface, and FIG. 5B schematically shows the reflected state of the LED emitted light in that case. It is shown. The reflected light spreads more on the curved surface. In addition, the shape of the outer peripheral side surface of this invention is not limited to FIG. 4A and FIG. 4B, For example, the shape embossed may be sufficient.
本考案の外周側面に備わる反射面は、金属薄膜をメッキ処理、真空蒸着、スパッタリングに外表面に形成したものが一般的である。しかしながら、銀反射層を内部に有する多層フィルムにより形成されたものがより好ましい。ここで、銀反射層を内部に有する多層フィルムとは、可撓性プラスチック基材に銀反射層を銀蒸着または銀コロイド分散液を塗布乾燥して形成し、保護層を積層したものである。可撓性プラスチック基材からなる反射面であるため、ＬＥＤ照明光源の形状に合わせた反射鏡形状に柔軟に対応できるからである。 The reflection surface provided on the outer peripheral side surface of the present invention is generally a metal thin film formed on the outer surface by plating, vacuum deposition, or sputtering. However, those formed of a multilayer film having a silver reflective layer therein are more preferable. Here, the multilayer film having a silver reflective layer is formed by laminating a protective layer with a silver reflective layer formed on a flexible plastic substrate by silver deposition or silver colloid dispersion. This is because the reflecting surface is made of a flexible plastic substrate and can flexibly correspond to the shape of a reflecting mirror that matches the shape of the LED illumination light source.
この考案は、環境に優しく省エネである電球型ＬＥＤ照明器具に利用できる。 This device can be used for a light bulb type LED lighting apparatus which is environmentally friendly and energy saving.
