Description

本発明は、照射方向を調整可能な照明装置に関する。   The present invention relates to an illumination device capable of adjusting an irradiation direction.

従来、照射方向を調整可能な照明装置としては、天井などに取り付ける取付部と光源を内蔵した光源ユニットとの間にヒンジを介在し、このヒンジを介して光源ユニットの向きを変えることにより、光源ユニットから照射する光源の光の照射方向を調整可能としたスポットライトが知られている。しかし、このスポットライトでは、ヒンジで回動可能とする範囲に照射方向の調整が限られてしまう（例えば、特許文献１参照。）。   Conventionally, as an illuminating device capable of adjusting the irradiation direction, a hinge is interposed between a mounting portion attached to a ceiling or the like and a light source unit incorporating a light source, and the direction of the light source unit is changed through the hinge to thereby change the light source. There is known a spotlight that can adjust the irradiation direction of light from a light source emitted from a unit. However, in this spotlight, adjustment of the irradiation direction is limited to a range that can be rotated by a hinge (see, for example, Patent Document 1).

また、光源に発光ダイオードを用いて、任意に照射方向を調整可能とした小形のダウンライトがある。このダウンライトでは、光源を内蔵する光源ユニットを球形に形成し、この光源ユニットの一部に内蔵する光源の光を外部へ照射する照射口部を設けており、この光源ユニットを照射口部側からリング状のホルダに係合し、光源ユニットの照射口部に対して反対側に板ばねを押し当ててホルダとの間に光源ユニットを保持している。光源ユニットの照射口部の向きを可変操作することにより、光源ユニットをホルダおよび板ばねとの接触抵抗に抗しながら摺動させて照射方向を調整している。
特開２００２−３０４９０４号公報（第１０頁、図３４−３５） In addition, there is a small downlight that uses a light emitting diode as a light source and can arbitrarily adjust the irradiation direction. In this downlight, a light source unit containing a light source is formed in a spherical shape, and an irradiation port portion for irradiating the light of the light source built in a part of the light source unit to the outside is provided. Is engaged with a ring-shaped holder, and a leaf spring is pressed against the irradiation port of the light source unit on the opposite side to hold the light source unit between the holder and the holder. By variably operating the direction of the irradiation port of the light source unit, the irradiation direction is adjusted by sliding the light source unit against the contact resistance between the holder and the leaf spring.
JP 2002-304904 A (page 10, FIG. 34-35)

しかしながら、光源に発光ダイオードを用いて、任意に照射方向を調整可能とした小形のダウンライトでは、光源ユニットの照射口部に対して反対側の１点のみに板ばねが接触してホルダに押し付けているだけで摩擦抵抗が低いため、光源ユニットを保持するのに十分な保持力が得られず、光源ユニットが動き回って照射方向がずれやすい問題がある。例えば、このダウンライトを車両の読書灯などに使用した場合、車両の振動で光源ユニットが動き回って照射方向がずれやすい。また、板ばねによる押圧力を強くしても、摩擦抵抗があまり高くならないばかりか、板ばねの押圧力に抗して組み立てる際の組立性が低下してしまい、構造的にも強固にしなければならなくなる。   However, in a small downlight that uses a light emitting diode as the light source and the irradiation direction can be adjusted arbitrarily, the leaf spring contacts only one point on the opposite side of the irradiation port of the light source unit and presses it against the holder. However, since the frictional resistance is low, a sufficient holding force for holding the light source unit cannot be obtained, and there is a problem that the irradiation direction tends to shift due to the movement of the light source unit. For example, when this downlight is used as a reading light for a vehicle, the light source unit is moved around by the vibration of the vehicle, and the irradiation direction tends to shift. In addition, even if the pressing force by the leaf spring is increased, the frictional resistance does not increase so much, and the assembling property at the time of assembling against the pressing force of the leaf spring is reduced, and the structure must be strengthened. No longer.

本発明は、このような点に鑑みなされたもので、光源ユニットの十分な保持力を確保できて光源ユニットを確実に保持でき、しかもその保持力を一定にできて操作性を安定させることができる照明装置を提供することを目的とする。   The present invention has been made in view of the above points, and can secure a sufficient holding force of the light source unit, reliably hold the light source unit, and can maintain the holding force constant to stabilize the operability.

As a result, the frictional resistance between the spherical surface portion 24 of the light source unit main body 22 and the holder 13 and the retainer 14 can be increased, and sufficient holding force of the light source unit 12 can be secured. The holding power of the light source unit 12 can be made constant by urging the light source unit main body 22 in a direction in which the light source unit body 22 is sandwiched between the light source unit 14 and the light source unit 14. Therefore, for example, even when the lighting device 11 is applied to a vehicle, the light source unit 12 can be prevented from moving due to vibration of the vehicle and the irradiation direction can be prevented from changing, and the irradiation direction can be changed by changing the direction of the irradiation port 25. In order to adjust, the operability when rotating the light source unit main body 22 relative to the holder 13 and the retainer 14 can be stabilized.

また、ホルダ13、リテーナ14および連結具15は、リング状に設けて同軸に配置したことにより、光源ユニット本体22の球面部24の周方向にバランスよく保持力を付与でき、光源ユニット12の軸ずれを防止できるとともに、光源ユニット12の操作性を安定させることができる。   Further, the holder 13, the retainer 14, and the connector 15 are provided in a ring shape and arranged coaxially, so that a holding force can be imparted in a balanced manner in the circumferential direction of the spherical surface portion 24 of the light source unit main body 22, and the axis of the light source unit 12 The displacement can be prevented and the operability of the light source unit 12 can be stabilized.

また、リテーナ14および連結具15をリング状に設けているため、光源ユニット本体22の照射口部25に対して反対側に放熱体26を設けることができ、この放熱体26により、光源ユニット本体22を小形化しても、発光ダイオード21から光源ユニット本体22に伝わる熱の放熱性を向上できる。または、放熱性を向上させることにより、発光ダイオード21に対する投入電力を増加させることができ、明るさを向上できる。   Further, since the retainer 14 and the connector 15 are provided in a ring shape, a heat radiator 26 can be provided on the opposite side to the irradiation port 25 of the light source unit main body 22, and this heat radiator 26 allows the light source unit main body to be provided. Even if the size of 22 is reduced, the heat dissipating property of the heat transmitted from the light emitting diode 21 to the light source unit body 22 can be improved. Alternatively, by improving the heat dissipation, the input power to the light emitting diode 21 can be increased, and the brightness can be improved.

また、リテーナ14の位置決め溝42と連結具15の位置決め部53との係合により、光源ユニット本体22の操作時にリテーナ14が回動するのを規制し、光源ユニット本体22の操作性を安定させることができる。   Further, the engagement between the positioning groove 42 of the retainer 14 and the positioning portion 53 of the connector 15 restricts the rotation of the retainer 14 during the operation of the light source unit main body 22, and stabilizes the operability of the light source unit main body 22. be able to.
