Description

本発明は、発光ダイオード（ＬＥＤ）を用いた照明装置に関し、特に、屋外の装飾照明に用いられる照明装置に係わるものである。   The present invention relates to a lighting device using a light emitting diode (LED), and more particularly to a lighting device used for outdoor decorative lighting.

従来から、屋外用の装飾照明として、点状光源をライン状に接続させた照明装置が用いられている。例えば特許第４７０３１３２号公報（特許文献１）には、ライン状の照明装置を、外壁や屋根の外郭に沿わせて設置させ、屋外の装飾照明として用いるものが知られている。   2. Description of the Related Art Conventionally, an illumination device in which point light sources are connected in a line shape has been used as decorative illumination for outdoor use. For example, Japanese Patent No. 4703132 (Patent Document 1) is known in which a line-shaped lighting device is installed along an outer wall or a roof outline and used as outdoor decorative lighting.

上記装飾用の照明装置は、設置の際の向きや配置によって照明装置の周囲に明暗が形成されてしまうと装飾の美観性が変わってしまうため、出射された光をどの方向からも視認できるよう、光が全周囲に出射されることが望ましい。
例えば特許第４１４３０７４号公報（特許文献２）では、ＬＥＤチップを覆うように光透過性樹脂を形成し、ＬＥＤからの出射光が側面方向や下面方向に反射や屈折させることで、装飾効果を高めることが記載されている。 The decoration lighting device can change the aesthetics of the decoration if light and darkness is formed around the lighting device depending on the orientation and arrangement during installation, so that the emitted light can be seen from any direction. It is desirable that the light is emitted all around.
For example, in Japanese Patent No. 4143074 (Patent Document 2), a light-transmitting resin is formed so as to cover the LED chip, and light emitted from the LED is reflected or refracted in the side surface direction or the bottom surface direction, thereby enhancing the decoration effect. It is described.

また一方で、屋外用の装飾照明は雨風に曝される可能性があることから、防水性の高い装置設計が必要とされている。例えば登録実用新案第３１１０１１４号公報（特許文献３）では、灯具周囲を覆うように保護カバーを設けることが記載されている。特に、透光性の封体と、給電部を収容する口金との隙間を覆うように防水保護カバーを設けることが望ましい。
しかしながら、特許文献３に記載の構成では、十分な防水性を確保することができない。また防水性を高めつつも、ＬＥＤからの出射光が全周囲に照射され、高い装飾効果を備えていなければならない。 On the other hand, outdoor decorative lighting is likely to be exposed to rain and wind, and thus a highly waterproof device design is required. For example, registered utility model No. 3110114 (Patent Document 3) describes that a protective cover is provided so as to cover the periphery of the lamp. In particular, it is desirable to provide a waterproof protective cover so as to cover the gap between the translucent sealing body and the base that accommodates the power feeding portion.
However, with the configuration described in Patent Document 3, sufficient waterproofness cannot be ensured. Moreover, while improving waterproofness, the emitted light from LED must be irradiated to the whole periphery, and it should have the high decoration effect.

特許第４７０３１３２号公報Japanese Patent No. 4703132 特許第４１４３０７４号公報Japanese Patent No. 4143074 登録実用新案第３１１０１１４号公報Registered Utility Model No. 3110114

本発明は、上記従来技術の問題点に鑑みて、発光ダイオード（ＬＥＤ）を用いた装飾用照射装置において、装飾効果を損なうことなく、かつ、屋外での使用を考慮して防水性を向上させた照明装置を提供するものである。   In view of the above-mentioned problems of the prior art, the present invention improves the waterproofness in a decorative irradiation device using a light emitting diode (LED) without sacrificing the decorative effect and considering outdoor use. A lighting device is provided.

また、発光部に連設された封止部が収容保持される口金部の内部に防水カバーを設け、口金の締付け部材によって、封止部と防水カバーとの密封性を高めることができ、これによって口金内部への防水性を一段と高めることができる。更には、この締付け部材も透光性であるので、照射装置の周囲に影を作るようなこともない。 According to the light source unit of the present invention, a light-transmitting protective cover is provided on the lower outer periphery of the light emitting unit to prevent rainwater from entering, and since the protective cover is light-transmitting, light is emitted to the entire periphery. Therefore, light and darkness will not be formed around the lighting device, and the aesthetics of the decoration will not change.
In addition, a waterproof cover is provided inside the base part in which the sealing part connected to the light emitting part is accommodated and held, and a sealing member between the sealing part and the waterproof cover can be improved by a fastening member of the base. Can further improve the waterproofness of the inside of the base. Furthermore, since this fastening member is also translucent, there is no shadow around the irradiation device.
