Description

本発明は、ＬＥＤを光源として天井材の埋設孔に埋め込まれて設置されるダウンライトや天井面から吊り下げられるペンダント等に適用されるＬＥＤ照明器具に関する。   The present invention relates to an LED lighting apparatus applied to a downlight, a pendant suspended from a ceiling surface, or the like, which is embedded in an embedding hole of a ceiling material using an LED as a light source.

従来より、セードの反射板の内側に光源を有し、セードの前面にカバーを設け、反射板の開口部にフランジを設けるとともにセードの内周面に支持突起を設けたＬＥＤ照明器具が知られている（例えば、特許文献１参照）。
特許文献１は、支持突起にフランジの背面を当接させ、カバーの開口周縁をフランジの前面に密着させた。 Conventionally, there has been known an LED lighting device having a light source inside a reflector of a shade, a cover provided on the front of the shade, a flange provided at the opening of the reflector, and a support protrusion provided on the inner peripheral surface of the shade. (For example, refer to Patent Document 1).
In Patent Document 1, the back surface of the flange is brought into contact with the support protrusion, and the opening peripheral edge of the cover is brought into close contact with the front surface of the flange.

特開平３−１０４１３号公報（図１、請求項１）Japanese Patent Laid-Open No. 3-10413 (FIG. 1, claim 1)

特許文献１は、カバーの外周とセードに内周との間への光の漏れを防止して光の放射範囲を整然と規制できる。
ところで、図５に示すように、特許文献１と同様に、ＬＥＤ発光部１０１を収容した灯具本体１０２に金属製のフード１０３を取り付けたＬＥＤ照明器具１００が提案されている。
ところが、このような従来のＬＥＤ照明器具１００は、フード１０３の外面から灯具本体１０２にねじ込まれたねじ１０４により、フード１０３が灯具本体１０２に固定されている。 In Patent Document 1, light emission between the outer periphery of the cover and the inner periphery of the shade can be prevented and the light emission range can be regulated in an orderly manner.
By the way, as shown in FIG. 5, as in Patent Document 1, an LED lighting apparatus 100 in which a metal hood 103 is attached to a lamp body 102 that houses an LED light emitting unit 101 has been proposed.
However, in such a conventional LED lighting apparatus 100, the hood 103 is fixed to the lamp body 102 by a screw 104 screwed into the lamp body 102 from the outer surface of the hood 103.

そのため、このような従来のＬＥＤ照明器具１００は、ねじ１０４が落下することがあるとともに、ねじ１０４を紛失してしまうとフード１０３を灯具本体１０２に取り付けることができない。

Furthermore, since the conventional LED lighting apparatus 100 requires a tool for screwing the screw 104, the assembly workability is not good, and the screw 104 is required, which is disadvantageous in terms of cost. It is.

一方、特許文献１と同様に、隔径方向に弾性反発力を蓄積しているばね部材を用いて、ＬＥＤ発光部を収容した灯具本体にフードを取り付けたＬＥＤ照明器具が提案されている。
しかし、このような従来のＬＥＤ照明器具は、ばね部材が落下することがあるとともに、ばね部材を紛失してしまうとフードを灯具本体に取り付けることができない。 On the other hand, as in Patent Document 1, an LED lighting apparatus has been proposed in which a hood is attached to a lamp body that houses an LED light-emitting portion using a spring member that accumulates an elastic repulsive force in the radial direction.
However, in such a conventional LED lighting apparatus, the spring member may fall, and if the spring member is lost, the hood cannot be attached to the lamp body.

本発明は、前述した課題を解決するためになされたものであり、その目的は、組立作業性を良好にでき、コスト面で有利にできるＬＥＤ照明器具を提供することにある。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an LED lighting apparatus that can improve assembly workability and can be advantageous in terms of cost.

The cylindrical portion 52 has an inner diameter L2 that is slightly smaller than the outer diameter L1 of the opening 17 of the lamp body 11, and the flange 53 has an inner diameter L3 that is smaller than the inner diameter L2 of the cylindrical portion 52. Have.

フード５１は、灯具本体１１に取り付けられる際に、筒状部５２が、その内径寸法Ｌ２を灯具本体１１の開口部１７の外径寸法Ｌ１よりも大きくなるように弾性変形される。
そして、フード５１は、内径寸法Ｌ２が灯具本体１１の開口部１７の外径寸法Ｌ１よりも大きくなるように弾性変形された状態で、灯具本体１１の開口部１７に被着される。
これにより、フード４１は、係止部５５が灯具本体１１の係止部受５６に係止され、弾性変形された際に蓄積された弾性復元力により、筒状部５２と灯具本体１１の開口部１７との間に大きな摩擦力が生じて灯具本体１１の開口部１７に弾性的に取り付けられる。 When the hood 51 is attached to the lamp main body 11, the cylindrical portion 52 is elastically deformed so that the inner diameter dimension L <b> 2 is larger than the outer diameter dimension L <b> 1 of the opening 17 of the lamp main body 11.
The hood 51 is attached to the opening 17 of the lamp main body 11 in a state where the inner diameter L2 is elastically deformed so as to be larger than the outer diameter L1 of the opening 17 of the lamp main body 11.
As a result, the hood 41 has an opening of the tubular portion 52 and the lamp body 11 due to the elastic restoring force accumulated when the locking portion 55 is locked to the locking portion receiver 56 of the lamp body 11 and elastically deformed. A large frictional force is generated between the lamp body 17 and the lamp body 11 and the lamp body 11 is elastically attached to the opening 17.

従って、フード５１は、従来のもののようなねじやばね部材を必要とせずに、灯具本体１１に取り付けられる。
なお、フード５１は、弾性部材により成形される筒状部５２が、弾性を有さない材料により成形される鍔部５３およびグレア制御部５４に２色成形されてもよい。 Therefore, the hood 51 is attached to the lamp body 11 without the need for screws and spring members as in the conventional case.
Note that the hood 51 may be formed in two colors, with the cylindrical portion 52 formed of an elastic member being formed into a flange portion 53 and a glare control portion 54 formed of a material having no elasticity.

ＬＥＤ照明器具５０は、電源ユニットから給電されることにより、ＬＥＤ１９が発光され、ＬＥＤ１９の出射光が配光制御部１３に入射され、配光制御部１３がＬＥＤ１９からの光成分を出射部２０から出射する。
そして、ＬＥＤ照明器具５０は、フード５１のグレア制御部５４により、ＬＥＤ１９からの光成分により光害となるグレアを防止する。 The LED lighting device 50 is supplied with power from the power supply unit, so that the LED 19 emits light, the light emitted from the LED 19 enters the light distribution control unit 13, and the light distribution control unit 13 transmits the light component from the LED 19 from the light emission unit 20. Exit.
And the LED lighting fixture 50 prevents the glare which becomes a light damage by the light component from LED19 by the glare control part 54 of the food | hood 51. FIG.

ＬＥＤ照明器具５０によれば、フード５１が、灯具本体１１の係止部受５６に係止される係止部５５を有するために、強固な固定構造を取得できる。   According to the LED lighting device 50, since the hood 51 has the locking portion 55 that is locked to the locking portion receiver 56 of the lamp body 11, a strong fixing structure can be obtained.
