Description

本発明は、混色形の照明器具に関するものである。  The present invention relates to a color mixing type lighting apparatus.

発光色の異なる複数の蛍光ランプを器具本体に取付け、混色形照明を行うことは既知である。このような蛍光灯器具は市販されている。  It is known that a plurality of fluorescent lamps having different emission colors are attached to an apparatus body to perform mixed color illumination. Such fluorescent lamp fixtures are commercially available.

発光色の異なる蛍光ランプ・発光ダイオードを組み合わせることも考えられる。しかし、発光ダイオードは指向性の強い点光源であるため、単なる併用では均一な混色がなされ難く、違和感が生ずる。本発明はこの難点を安価に解決するものである。  It is also conceivable to combine fluorescent lamps and light emitting diodes having different emission colors. However, since the light-emitting diode is a point light source with strong directivity, it is difficult to achieve uniform color mixing with a simple combination, resulting in an uncomfortable feeling. The present invention solves this difficulty at low cost.

本発明に係る照明器具は拡散性発光管を具備する蛍光ランプを備える。前記蛍光ランプとは異なる発光色の光を投射する発光ダイオードを備える。前記発光ダイオードの光を前記拡散性発光管にて遮るように前記蛍光ランプ・前記発光ダイオード相互の配置を定める。  The luminaire according to the present invention includes a fluorescent lamp including a diffusive arc tube. A light emitting diode for projecting light of an emission color different from that of the fluorescent lamp is provided. The arrangement of the fluorescent lamp and the light emitting diode is determined so that the light from the light emitting diode is blocked by the diffusive light emitting tube.

本発明においては、発光ダイオードの光を拡散性発光管にて遮るように蛍光ランプ・発光ダイオード相互の配置を定める。このため、発光ダイオードの光は拡散性発光管を拡散透過し該拡散性発光管から出る本来の光と均一に混ざる。均整度の高い混光である。これはこれによれば、安価な優れた混色照明が実現する。  In the present invention, the mutual arrangement of the fluorescent lamp and the light emitting diode is determined so that the light of the light emitting diode is blocked by the diffusive light emitting tube. For this reason, the light from the light emitting diode diffuses and transmits through the diffusive arc tube and is uniformly mixed with the original light emitted from the diffusive arc tube. The light is well-balanced. According to this, an inexpensive and excellent color mixing illumination is realized.

図１・図２を用いて本発明の実施形態について説明する。本発明器具は、拡散性発光管８・９を具備する蛍光ランプ１１を備える。前記蛍光ランプ１１とは異なる発光色の光を投射する発光ダイオード５を備える。前記発光ダイオード５の光を前記拡散性発光管８・９にて遮るように前記蛍光ランプ１１及び前記発光ダイオード５相互の配置を定める。
蛍光ランプ１１は二重環形の１本の環状蛍光ランプである。それは外側の拡散性発光管８および内側の拡散性発光管９を具備する。蛍光ランプ１１は昼光色形であり、色温度６７００Ｋの青成分の多い光を出す。発光管８・９には蛍光体が塗布されており、光学的には必然的に拡散性を呈する。図１における１１の引き出し線の箇所は口金部である。１２は拡散性発光管８・９相互を内通させるブリッジ部である。An embodiment of the present invention will be described with reference to FIGS. The instrument of the present invention includes a fluorescent lamp 11 having diffusible arc tubes 8 and 9. A light emitting diode 5 for projecting light of a color different from that of the fluorescent lamp 11 is provided. The mutual arrangement of the fluorescent lamp 11 and the light emitting diode 5 is determined so that the light from the light emitting diode 5 is blocked by the diffusive light emitting tubes 8 and 9.
The fluorescent lamp 11 is a single annular fluorescent lamp having a double ring shape. It comprises an outer diffusive arc tube 8 and an inner diffusive arc tube 9. The fluorescent lamp 11 has a daylight color shape and emits light with a blue component having a color temperature of 6700K. The fluorescent tubes 8 and 9 are coated with a fluorescent material, and inevitably exhibit diffusibility. In FIG. 1, 11 lead wire portions are cap portions. Reference numeral 12 denotes a bridge portion that allows the diffusive arc tubes 8 and 9 to pass through each other.

発光ダイオード５は赤色系発光形のものである。多数の発光ダイオード５が発光管に沿って配置されている。発光ダイオード５の光は拡散性発光管を図２の丸１・２・３のごとくに拡散透過し、該拡散性発光管から出る本来の光と均一に混ざる。発光ダイオード５の光を拡散させる部材はそれ専用のものではなく、蛍光ランプ８・９に必然的に具備される拡散性発光管である。
図１においては、蛍光ランプ８・９を透視状に描き、発光ダイオード５を見せる。図２では器具本体１が簡略的に図示され、また使用状態とは上下が逆に描かれている。さらに、器具本体１に装着されるランプフォルダ（蛍光ランプ８・９を着脱自在に保持する）の図示を省略した。The light emitting diode 5 is of a red light emitting type. A number of light emitting diodes 5 are arranged along the arc tube. The light from the light-emitting diode 5 diffuses and transmits through the diffusive arc tube as indicated by circles 1, 2, and 3 in FIG. 2 and is uniformly mixed with the original light emitted from the diffusive arc tube. The member for diffusing the light of the light emitting diode 5 is not a dedicated member, but is a diffusive arc tube necessarily provided in the fluorescent lamps 8 and 9.
In FIG. 1, the fluorescent lamps 8 and 9 are drawn in a perspective manner to show the light emitting diode 5. In FIG. 2, the instrument main body 1 is illustrated in a simplified manner, and is drawn upside down from the state of use. Further, the illustration of the lamp folder (which holds the fluorescent lamps 8 and 9 detachably) attached to the instrument body 1 is omitted.

実用上は次のようにすることができる。
蛍光ランプ１１を調光制御する場合はその光束変化に応じて赤色発売ダイオード５の光出力も変化させ、常に一定の色合いに保持する。このためには、両者を連動して調光させる手段を付属させる。複数の蛍光ランプ１１を具備する場合、その一部が寿命等で消灯したときに、それと連動して蛍光ランプ近傍の発光ダイオード５を消灯させ、器具全体の色合いの不所望な変化を防止する。Practically, it can be as follows.
When the dimming control of the fluorescent lamp 11 is performed, the light output of the red sale diode 5 is also changed according to the change of the luminous flux, and is always kept at a constant color. For this purpose, means for adjusting the light in conjunction with each other is attached. When a plurality of fluorescent lamps 11 are provided, when part of the lamps are extinguished due to their lifetime or the like, the light-emitting diodes 5 in the vicinity of the fluorescent lamps are extinguished in conjunction therewith to prevent undesired changes in the color of the entire apparatus.
