Description

本発明は、赤外線リモコンから送信される赤外線信号によって、点灯制御される照明器具に関するものである。   The present invention relates to a lighting fixture that is controlled to be turned on by an infrared signal transmitted from an infrared remote controller.

赤外線信号によって制御が可能な照明器具において、その赤外線信号の到達性能に関しては、従来から様々な工夫がなされている。特に照明器具のデザイン性を考慮して照明器具内部に赤外線信号の受信手段を内蔵する場合には光源からの光ノイズの入射が回避し難く、これによる赤外線信号の到達性能の低下が課題となることが多い。   In the lighting fixtures that can be controlled by infrared signals, various approaches have been conventionally made regarding the arrival performance of the infrared signals. In particular, when an infrared signal receiving means is built in the lighting fixture in consideration of the design of the lighting fixture, it is difficult to avoid the incidence of optical noise from the light source. There are many cases.

こうした課題に対して、赤外線信号を受信する受信部の位置や配置角度などを工夫することで対策をした例として、特許文献1により開示されている従来例を示す。   A conventional example disclosed in Patent Document 1 is shown as an example of countermeasures against such problems by devising the position and arrangement angle of a receiving unit that receives an infrared signal.

図3は本従来例の照明器具の概略的な断面図である。   FIG. 3 is a schematic cross-sectional view of the conventional lighting fixture.

本従来例の照明器具の構成は、照明器具本体301と、赤外線信号受信部302と、それぞれ出力および外形が異なる環状型蛍光ランプ307a、307b、307cと、環状型蛍光ランプを器具本体に固定するランプ支持具303と、器具本体内部から前記環状型蛍光ランプにそれぞれ口金308a、308b、308cを介して点灯出力を供給するソケット304と、照明器具本体301に取り付けられ器具下面全体を覆う光透過性の照明器具グローブ305からなる。   The configuration of the lighting fixture of this conventional example is that the lighting fixture main body 301, the infrared signal receiving unit 302, the annular fluorescent lamps 307a, 307b, 307c having different outputs and outer shapes, and the annular fluorescent lamp are fixed to the fixture main body. A lamp support 303, a socket 304 for supplying a lighting output from the inside of the fixture body to the annular fluorescent lamp via the caps 308a, 308b, and 308c, respectively, and a light transmitting property that is attached to the lighting fixture body 301 and covers the entire lower surface of the fixture Lighting fixture globe 305.

図3では、それぞれ径の異なる3灯の環状型蛍光ランプ307a、307b、307cが、照明器具本体301上に設置されており、照明器具本体301の中心Oと、環状型蛍光ランプ307a、307b、307cの口金308a、308b、308cの中心とを結ぶ線の延長線M上において、環状型蛍光ランプ301aの外側に赤外線信号受信部302の受信窓302′の中心nを配置するようにして、赤外線信号受信部302を設置している。   In FIG. 3, three annular fluorescent lamps 307a, 307b, and 307c having different diameters are installed on the lighting fixture main body 301, and the center O of the lighting fixture main body 301 and the annular fluorescent lamps 307a, 307b, On the extended line M connecting the centers of the bases 308a, 308b, and 308c of 307c, the center n of the receiving window 302 'of the infrared signal receiving unit 302 is arranged outside the annular fluorescent lamp 301a so that the infrared ray is received. A signal receiving unit 302 is installed.

このように構成することで本従来例の照明器具は、環状型蛍光ランプ307a、307b、307cの多灯点灯による光ノイズの比較的少ない位置に赤外線信号受信部302が配置され、その赤外線信号受信部302の受信窓302′が赤外線リモコン(図示無し)からの赤外線信号を受信することにより、リモコン制御機能の向上を図っている。   With this configuration, the illumination fixture of this conventional example has the infrared signal receiving unit 302 disposed at a position where the light noise due to the multiple lighting of the annular fluorescent lamps 307a, 307b, and 307c is relatively small. The reception window 302 ′ of the unit 302 receives an infrared signal from an infrared remote controller (not shown), thereby improving the remote control function.

また、多灯の環状型蛍光ランプ307a、307b、307cの口金308a、308b、308cの中心を結ぶ線の延長線M(多灯の環状型蛍光ランプ307a、307b、307cのランプの外面における接線の延長線N)と直行する方向線N′上において、赤外線信号受信部302に遮蔽壁Kを設けてその遮蔽壁Kにより環状型蛍光ランプ307a、307b、307cの多灯点灯時の照明グローブ305内面から反射光による光ノイズを遮蔽することで赤外線信号の受信感度を向上させている。さらに、照明器具グローブ305に赤外線信号受信部302の陰影が写ることを防止している。   Further, an extension M of a line connecting the centers of the caps 308a, 308b, 308c of the multi-ring annular fluorescent lamps 307a, 307b, 307c (a tangential line on the outer surface of the multi-lamp annular fluorescent lamp 307a, 307b, 307c). On the direction line N ′ perpendicular to the extension line N), a shielding wall K is provided in the infrared signal receiving unit 302, and the inner surface of the illumination globe 305 when the annular fluorescent lamps 307a, 307b, 307c are turned on by the shielding wall K. The reception sensitivity of infrared signals is improved by shielding the optical noise caused by the reflected light. Furthermore, the shade of the infrared signal receiver 302 is prevented from appearing on the lighting fixture globe 305.

このように、本従来例では、環状型蛍光ランプ307a、307b、307cの多灯点灯による光ノイズの少ない位置に赤外線信号受信部302を配置し、さらに、赤外線信号受信部302に設けた遮蔽壁Kにより、照明器具グローブ305の内面からの反射光が誤った制御信号として赤外線信号受信部302の受光窓302′に入ってくることを防止し、蛍光ランプの低温始動時等における光ノイズに起因した誤動作を防止して赤外線信号の受信感度を向上させ、さらには、照明器具グローブ305に赤外線信号受信部302の陰影が写ることも防止している。   As described above, in this conventional example, the infrared signal receiving unit 302 is arranged at a position where the light noise due to the multiple lighting of the annular fluorescent lamps 307a, 307b, and 307c is small, and the shielding wall provided in the infrared signal receiving unit 302 is further provided. K prevents the reflected light from the inner surface of the lighting fixture globe 305 from entering the light receiving window 302 ′ of the infrared signal receiving unit 302 as an erroneous control signal, and is caused by light noise during cold start of the fluorescent lamp. Thus, the infrared signal reception sensitivity is improved by preventing the erroneous operation, and the shadow of the infrared signal reception unit 302 is also prevented from appearing on the lighting fixture globe 305.

この他にも、受信手段の配置を工夫することで対策をした例としては特許文献2に開示されているような吊り上げ器具がある。図4は本従来例の照明器具の部分断面図である。   In addition, there is a lifting device as disclosed in Patent Document 2 as an example of countermeasures by devising the arrangement of the receiving means. FIG. 4 is a partial cross-sectional view of the conventional lighting fixture.

本従来例の照明器具の構成は、照明器具本体401、赤外線リモコン406からの赤外線信号を受信する受信部402、光不透過性材料からなるセード403、光透過性材料からなるグローブ404、蛍光ランプ405からなり、407は天井である。   The configuration of the luminaire of this conventional example includes a luminaire main body 401, a receiving unit 402 that receives an infrared signal from an infrared remote controller 406, a shade 403 made of a light impermeable material, a globe 404 made of a light transmissive material, and a fluorescent lamp. 405, and 407 is a ceiling.

照明器具本体401の下面部には蛍光ランプ405が取り付けられ、上面部に受信部402が配置されている。照明器具本体401にはセード403が載置され、セード403にはグローブ404が取り付けられている。図4中の位置において赤外線リモコン406を操作すると、赤外線リモコン406から赤外線信号が出射される。この赤外線信号が、天井407で反射されて受信部402に入り、蛍光ランプ405の点灯、消灯等の動作を行うようになっている。セード403を光不透過性材料で構成しているため、ランプ点灯時にも蛍光ランプ405の光が受信部402へと入射されることはなく、光ノイズの影響を低減して誤動作や不動作を防止している。   A fluorescent lamp 405 is attached to the lower surface portion of the lighting fixture main body 401, and the receiving portion 402 is disposed on the upper surface portion. A shade 403 is placed on the lighting fixture body 401, and a globe 404 is attached to the shade 403. When the infrared remote controller 406 is operated at the position in FIG. 4, an infrared signal is emitted from the infrared remote controller 406. The infrared signal is reflected by the ceiling 407 and enters the receiving unit 402, and operations such as turning on and off the fluorescent lamp 405 are performed. Since the seed 403 is made of a light-impermeable material, the light of the fluorescent lamp 405 is not incident on the receiving unit 402 even when the lamp is lit, reducing the influence of optical noise and preventing malfunctions and malfunctions. It is preventing.

このように、この従来例では光源からの直接光が入射されない照明器具本体401上面に赤外線信号の受信部402を配置し、赤外線信号に関しては天井での反射を利用して受信することにより、赤外線信号の到達性能向上を図っている。   As described above, in this conventional example, the infrared signal receiving unit 402 is disposed on the upper surface of the luminaire main body 401 on which direct light from the light source is not incident, and the infrared signal is received by utilizing reflection on the ceiling. The signal arrival performance is improved.

前述した2つの従来例のように受信手段の配置に関する工夫以外にも、特許文献3に開示されているように、赤外線信号の入射角を制限し、光学フィルターを介して受信することで光源からの光ノイズによる影響を低減して赤外線信号の到達性能を確保しているものも知られている。   In addition to the device related to the arrangement of the receiving means as in the two conventional examples described above, as disclosed in Patent Document 3, the incident angle of the infrared signal is limited, and the light is received through the optical filter. It is also known that the effect of the optical noise is reduced to ensure the arrival performance of the infrared signal.

図5は本従来例の受信部部分の断面図である。   FIG. 5 is a cross-sectional view of the receiving portion of this conventional example.

この受信部は先に図3で示した従来例のように、蛍光ランプからの光ノイズの入射が避けられない位置に配置されるものであり、赤外線信号Irを受信する受光素子501と、光学フィルター502と、受光素子501を収めた受光モジュールの外郭503と、受光モジュール503を実装したプリント基板504と、受信部全体を覆う樹脂ケース505からなる。   As in the conventional example shown in FIG. 3, the receiving unit is arranged at a position where light noise from the fluorescent lamp is unavoidable. The receiving unit 501 receives the infrared signal Ir, and the optical unit. The filter 502, a light receiving module outer wall 503 in which the light receiving element 501 is housed, a printed circuit board 504 on which the light receiving module 503 is mounted, and a resin case 505 that covers the entire receiving unit.

受光素子501の前面に設置された光学フィルター502は入射角θ=0°における透過ピーク波長λが約965nmであるバンドパス特性を持ち、受光素子501は、PINフォトダイオードからなるチップ506を透明樹脂からなるレンズ507でモールド形成して構成されている。   The optical filter 502 installed on the front surface of the light receiving element 501 has a bandpass characteristic with a transmission peak wavelength λ of about 965 nm at an incident angle θ = 0 °. The light receiving element 501 uses a chip 506 made of a PIN photodiode as a transparent resin. The lens 507 is formed by molding.

このように、光学フィルターによるノイズ遮断効果を十分に生かすため、受光素子501の指向特性をチップ506の位置をレンズ507に対して後退させるなどして改善し、その半値角を約35°以内にしている。これにより、光ノイズの遮断率が向上し、蛍光ランプの低温点灯初期時における赤外線信号到達性能向上を図っている。   As described above, in order to sufficiently utilize the noise blocking effect by the optical filter, the directivity characteristics of the light receiving element 501 are improved by retreating the position of the chip 506 with respect to the lens 507, and the half-value angle is set within about 35 °. ing. Thereby, the blocking rate of optical noise is improved, and the infrared signal arrival performance at the initial stage of low temperature lighting of the fluorescent lamp is improved.

従来例として図3に示した特許文献1の照明器具によると、赤外線信号は光透過性の照明器具グローブを貫通して受信部へ到達させる必要があるため、照明器具グローブには赤外線信号を通しやすい性質であることが要求され、透過率を下げて雰囲気を演出するものや模様を印刷することにより高級感を出す照明器具グローブ等には制約がかかることになる。   According to the illuminating device of Patent Document 1 shown in FIG. 3 as a conventional example, the infrared signal needs to pass through the light-transmitting luminaire glove and reach the receiving unit. It is required to have an easy property, and there is a restriction on a lighting fixture glove or the like that produces an atmosphere by lowering the transmittance and that gives a high-class feeling by printing a pattern.

また、蛍光ランプの発光による直接光の受信部への入射を回避する内容においても、照明器具グローブの内側の面による反射光が受信部へ入射されることは避けがたく、この反射光が赤外線信号受信部には光ノイズとして影響してしまい、S/N比が下がってしまうことになるため照明器具グローブには前述の赤外線の透過性に加え、形状や反射率に制限を受ける。   In addition, it is unavoidable that the reflected light from the inner surface of the luminaire glove is incident on the receiver even in the content of avoiding the direct light incident on the receiver due to the light emitted from the fluorescent lamp. The signal receiving unit is affected as optical noise and the S / N ratio is lowered. Therefore, the lighting fixture glove is restricted by the shape and the reflectance in addition to the infrared transparency described above.

また、図3の例のように器具本体の外周に近い部分に傾けて赤外線信号受信部を配置した場合、全方向からの赤外線信号到達性能を確保するためには赤外線信号自体も照明器具グローブの内側の面による反射光で赤外線信号受信部へ入射され、この赤外線信号により制御が可能であることが必要になるため、形状や反射率に前記の制限と逆方向の制約を受けることになる。   In addition, when the infrared signal receiver is disposed at a position near the outer periphery of the fixture body as in the example of FIG. 3, the infrared signal itself is also included in the lighting fixture glove in order to ensure the infrared signal reachability from all directions. The reflected light from the inner surface is incident on the infrared signal receiving unit and must be controllable by the infrared signal. Therefore, the shape and the reflectance are restricted in the opposite direction to the above-described limitations.

また、従来例のようにそれぞれ定格出力および外径の異なる環状の蛍光ランプを同心円状に配置して口金の向きを揃え、その付近に赤外線信号受信部を配置した場合、つまり照明器具グローブの内部において明るさの低い部分に受信部を配置した場合、その部分の陰影が照明器具グローブの外側から見えてしまい、ランプイメージが低下するおそれがある。また、環状の蛍光ランプの外側に赤外線信号受信部を配置することにより、器具本体および照明器具グローブを蛍光ランプに対して過度に大きく設計する必要もあり、このことによっても照明器具グローブにおいて蛍光ランプ直近の部分とその外周部分との輝度比によるランプイメージが低下するおそれがある。   In addition, as in the conventional example, annular fluorescent lamps with different rated outputs and outer diameters are arranged concentrically to align the direction of the base, and an infrared signal receiver is arranged in the vicinity thereof, that is, inside the lighting fixture glove. In the case where the receiving unit is arranged in a portion with low brightness, the shadow of the portion can be seen from the outside of the lighting fixture globe, and the lamp image may be lowered. In addition, by arranging the infrared signal receiving unit outside the annular fluorescent lamp, it is necessary to design the fixture body and the lighting fixture globe to be excessively large relative to the fluorescent lamp. There is a risk that the lamp image due to the luminance ratio between the nearest part and the outer peripheral part thereof is lowered.

こうした問題に対しては図6に分解斜視図を示す照明器具のように、照明器具本体601に取り付けられた環状の蛍光ランプ602の内径内に赤外線信号受信部603を配置することが有効である(図6中604は、光透過性の照明器具グローブ)。   For such a problem, it is effective to arrange the infrared signal receiver 603 within the inner diameter of the annular fluorescent lamp 602 attached to the luminaire main body 601 as in the luminaire shown in the exploded perspective view in FIG. (604 in FIG. 6 is a light-transmitting lighting fixture glove).

しかし、この方法は例えば図7に示すような平面らせん形状の蛍光ランプ102を負荷とした場合には適用できず、問題は解消できない。   However, this method cannot be applied when, for example, a flat spiral fluorescent lamp 102 as shown in FIG. 7 is used as a load, and the problem cannot be solved.

従来例として図4に示した特許文献2の構成においては、天井407での反射率により赤外線信号が弱まり、天井表面の材質等によっては到達性能が低下する課題が存在し、さらに器具の直下の位置において赤外線リモコン406を操作した場合、赤外線リモコン406から出射された赤外線信号は光不透過性材料からなるセード403に蛍光ランプの発光とともに遮られて受信部402には到達しないため、蛍光ランプ405の動作を行うことができない。   In the configuration of Patent Document 2 shown in FIG. 4 as a conventional example, the infrared signal is weakened by the reflectance at the ceiling 407, and there is a problem that the reaching performance is lowered depending on the material of the ceiling surface, and further, the problem is directly below the appliance. When the infrared remote controller 406 is operated at the position, the infrared signal emitted from the infrared remote controller 406 is blocked by the shade 403 made of a light-impermeable material together with the light emission of the fluorescent lamp and does not reach the receiving unit 402. Can not be performed.

また、赤外線リモコン406からの赤外線信号を部屋の壁に向けて出射させ、壁で反射させてから天井407で再度反射させて受信部402へ到達させる経路も考えられるが、その場合には赤外線リモコン406の方向づけが困難であるだけでなく、赤外線信号が弱まり、実使用上、蛍光ランプ405を動作させるのは困難となる。   In addition, a route in which an infrared signal from the infrared remote controller 406 is emitted toward the wall of the room, reflected by the wall, and then reflected again by the ceiling 407 to reach the receiving unit 402 is conceivable. Not only is the orientation of 406 difficult, but the infrared signal is weakened, making it difficult to operate the fluorescent lamp 405 in actual use.

従来例として図5に示した特許文献3の受信部においては、光学フィルターの効果により光ノイズの遮断性能は向上するものの、その指向角度が限定されることにより、赤外線リモコン(図示無し)の位置により赤外線信号の到達性能が悪化することが考えられる。   In the receiving part of Patent Document 3 shown in FIG. 5 as a conventional example, although the optical noise blocking performance is improved by the effect of the optical filter, the position of the infrared remote controller (not shown) is limited by the limitation of the directivity angle. As a result, it is conceivable that the arrival performance of the infrared signal is deteriorated.

本発明は、上記事由に鑑みてなされたものであり、その目的は、赤外線リモコンを操作することによって点灯、消灯などの制御が可能である照明器具において、光源からの光ノイズの影響を排除して、複数方向からの赤外線信号到達性能を確保する照明器具を提供することにある。   The present invention has been made in view of the above reasons, and its purpose is to eliminate the influence of light noise from a light source in a lighting fixture that can be controlled to be turned on and off by operating an infrared remote controller. Thus, an object of the present invention is to provide a lighting fixture that ensures the arrival performance of infrared signals from a plurality of directions.

請求項1の発明は、光源と、赤外線リモコンから送信された赤外線信号を受信する受光素子と、赤外線リモコンから送信された赤外線信号を複数方向に向けて形成された複数の入射部から受光素子まで伝達する反射伝達経路を形成する中空構造の赤外線伝達手段と、受光素子で受信した赤外線信号に応じて光源の点灯制御を行う点灯装置とを備え、受光素子および入射部を光源が放射する光が入射しない位置に配置することを特徴とする照明器具。   According to a first aspect of the present invention, there is provided a light source, a light receiving element for receiving an infrared signal transmitted from the infrared remote controller, and a plurality of incident portions formed from the infrared signal transmitted from the infrared remote controller in a plurality of directions to the light receiving element. A hollow structure infrared transmission means that forms a reflection transmission path for transmission and a lighting device that controls lighting of the light source according to an infrared signal received by the light receiving element, and the light emitted from the light source through the light receiving element and the incident portion A lighting apparatus characterized by being arranged at a position where it does not enter.

この発明によれば、照明光源からの放射する光による光ノイズの影響を受けない赤外線信号の受信経路を構成することができ、かつ複数方向からの赤外線信号を反射によって確実に受光素子に入射することができ、受信感度を確保することができる。   According to the present invention, an infrared signal receiving path that is not affected by optical noise caused by light emitted from an illumination light source can be configured, and infrared signals from a plurality of directions are reliably incident on a light receiving element by reflection. And reception sensitivity can be ensured.

請求項2の発明は、一面に前記光源と当該光源を覆うグローブを配置した光不透過性の材質からなる器具本体の他面側に前記受光素子と前記赤外線伝達手段を配置することを特徴とする請求項1記載の照明器具。   The invention of claim 2 is characterized in that the light receiving element and the infrared transmission means are arranged on the other side of the instrument body made of a light-impermeable material in which the light source and a glove covering the light source are arranged on one surface. The lighting fixture according to claim 1.

この発明によれば、受光素子と赤外線伝達手段を、外観上から隠れた部分に配置することができるため、照明器具グローブに受光素子の陰影が写ることによるランプイメージの悪化はない。さらに、照明器具本体および照明器具グローブの大きさを光源に対して過度に大きくする必要がなく、照明器具グローブに赤外線を通過させる必要がないため照明器具グローブの形状や材質、デザインへの制約を抑制することができる。   According to the present invention, since the light receiving element and the infrared transmission means can be arranged in a portion hidden from the appearance, there is no deterioration of the lamp image due to the shadow of the light receiving element appearing on the lighting fixture glove. Furthermore, it is not necessary to make the size of the luminaire main body and the luminaire globe excessively large relative to the light source, and it is not necessary to allow infrared rays to pass through the luminaire glove, thus limiting the shape, material, and design of the luminaire globe. Can be suppressed.

以上説明したように、本発明では、赤外線リモコンを操作することによって点灯、消灯などの制御が可能である照明器具において、光源からの光ノイズの影響を排除して、複数方向からの赤外線信号到達性能を確保することができるという効果がある。   As described above, the present invention eliminates the influence of light noise from a light source and can reach infrared signals from multiple directions in a lighting fixture that can be turned on and off by operating an infrared remote controller. There is an effect that performance can be secured.

FIG. 1 shows a cross section inside the lighting fixture.

この照明器具は天井直付け形態の照明器具であり、その構成は、天井に固定される円形の照明器具本体101と、照明器具本体101の下面に取り付けられる平面らせん形状の蛍光ランプ102と、蛍光ランプ102を覆うように照明器具本体101の下部に取り付けられる光透過性の照明器具グローブ103と、赤外線信号の受光素子104と、赤外線信号の反射経路となる赤外線反射伝達材105からなる。そして、天井面106に備え付けられた給電部品107により商用電源からの電力の供給を得て、かつ照明器具本体101を天井面106に保持している。平面らせん形状の蛍光ランプ102は図7で示す形状の蛍光ランプである。   The lighting fixture is a ceiling-mounted lighting fixture, and the configuration thereof includes a circular lighting fixture body 101 fixed to the ceiling, a flat spiral fluorescent lamp 102 attached to the lower surface of the lighting fixture body 101, and a fluorescent lamp. It comprises a light-transmitting luminaire globe 103 attached to the lower part of the luminaire main body 101 so as to cover the lamp 102, an infrared signal light receiving element 104, and an infrared reflection transmission material 105 serving as a reflection path for the infrared signal. The power supply component 107 provided on the ceiling surface 106 obtains power from a commercial power source and holds the lighting fixture body 101 on the ceiling surface 106. The flat spiral fluorescent lamp 102 is a fluorescent lamp having the shape shown in FIG.

ここで、照明器具本体101は金属製で光不透過である。照明器具本体101内部には蛍光ランプ102を高周波点灯させる点灯装置108が内蔵されており、器具本体101の下面に取り付けられたランプソケット(図示無し)を通じて蛍光ランプ102に点灯電力を供給している。さらに、同じく照明器具本体101の下面に配置したランプ支持具109により蛍光ランプ102を器具本体101に保持している。また、椀型の照明器具グローブ103の開口部の外周は、照明器具本体101の外周と略一致する。   Here, the luminaire main body 101 is made of metal and does not transmit light. A lighting device 108 for turning on the fluorescent lamp 102 at a high frequency is built in the lighting fixture main body 101, and lighting power is supplied to the fluorescent lamp 102 through a lamp socket (not shown) attached to the lower surface of the fixture main body 101. . Further, the fluorescent lamp 102 is held on the fixture main body 101 by a lamp support 109 arranged on the lower surface of the luminaire fixture main body 101. In addition, the outer periphery of the opening of the bowl-shaped lighting fixture globe 103 substantially coincides with the outer periphery of the lighting fixture main body 101.

受光素子104は照明器具本体101の上面に配置され、蛍光ランプ102は照明器具本体101の下面に配置される。すなわち受光素子104と蛍光ランプ102は光を透過させない照明器具本体101を挟んで反対側に配置されている。このため、照明器具の点灯中においても受光素子104には蛍光ランプ102からの直接光の入射がない位置関係に配置されていると言える。   The light receiving element 104 is disposed on the upper surface of the luminaire main body 101, and the fluorescent lamp 102 is disposed on the lower surface of the luminaire main body 101. That is, the light receiving element 104 and the fluorescent lamp 102 are disposed on the opposite sides with the lighting fixture body 101 that does not transmit light interposed therebetween. For this reason, it can be said that the light receiving element 104 is arranged in a positional relationship where no direct light is incident from the fluorescent lamp 102 even during lighting of the lighting fixture.

次に、赤外線信号の反射経路を構成する赤外線反射伝達材105を図2に示す。   Next, FIG. 2 shows the infrared reflection transmission material 105 constituting the reflection path of the infrared signal.

赤外線信号の反射経路を構成する赤外線反射伝達材105は光不透過性の材質でできた断面が矩形状の中空構造の円環状の部品であり、内面は赤外線信号が反射しやすいように表面に塗装処理を施している。これを円形の照明器具本体101上面の外周と赤外線反射伝達材105の外周とが重なるように配置している。赤外線反射伝達材105はその外周側面に120度の間隔で3箇所の開口部201が形成されており、開口部201の上部につば部201aが外側へ突設されている。また、赤外線反射伝達材105の内周側面に1箇所の開口部202を形成しており、開口部202の上方と側方から囲むようにつば部202aが突設されており、この開口部202のつば部202aと照明器具本体101の上面との間の囲まれた場所に受光素子104を配置している。   The infrared reflection transmission material 105 constituting the reflection path of the infrared signal is an annular part having a hollow structure with a rectangular cross section made of a light-impermeable material, and the inner surface is provided on the surface so that the infrared signal is easily reflected. Paint treatment is applied. This is arranged so that the outer periphery of the upper surface of the circular lighting fixture body 101 and the outer periphery of the infrared reflection transmission material 105 overlap. The infrared reflection transmission material 105 has three openings 201 formed at intervals of 120 degrees on the outer peripheral side surface thereof, and a collar portion 201a is projected outward from the upper portion of the opening 201. In addition, one opening 202 is formed on the inner peripheral side surface of the infrared reflection transmission material 105, and a collar 202a is provided so as to protrude from above and from the side of the opening 202, and this opening 202 is provided. The light receiving element 104 is arranged at a place enclosed between the collar portion 202 a and the upper surface of the luminaire main body 101.

赤外線反射伝達材105の外周側面3箇所の開口部201は赤外線リモコン(図示無し)による外部からの赤外線信号を入射する入射部を構成しており、内周側面1箇所の開口部202は、開口部201より入射した赤外線信号が赤外線反射伝達材105内で反射した後に受光素子104へ向けて出射する出射部を構成している。   The openings 201 at the three outer peripheral side surfaces of the infrared reflection transmitting material 105 constitute an incident portion for receiving an infrared signal from the outside by an infrared remote controller (not shown), and the opening 202 at one inner peripheral side surface is opened. An emission part that emits toward the light receiving element 104 after the infrared signal incident from the part 201 is reflected in the infrared reflection transmission material 105 is configured.

このような構成により、照明器具の外部からユーザーが操作することにより赤外線リモコン(図示無し)から送信された赤外線信号は、器具本体101の上面外周に配置されている赤外線反射伝達材105の外周側面に設けられた、いずれか1つ以上の開口部201から進入し、赤外線反射伝達材105内部で反射を繰り返した後、赤外線反射伝達材105の内周側面に設けられた開口部202を介して受光素子104へと到達することが可能になっている。そして、受信した赤外線信号に応じて点灯装置108が蛍光ランプ102の点灯制御を行う。   With such a configuration, an infrared signal transmitted from an infrared remote controller (not shown) by a user's operation from the outside of the lighting fixture is an outer peripheral side surface of the infrared reflection transmission material 105 disposed on the outer periphery of the upper surface of the fixture main body 101. After passing through any one or more openings 201 provided in the above, and repeatedly reflecting inside the infrared reflection transmission material 105, via the opening 202 provided on the inner peripheral side surface of the infrared reflection transmission material 105 It is possible to reach the light receiving element 104. Then, the lighting device 108 controls the lighting of the fluorescent lamp 102 according to the received infrared signal.

そして、受光素子104は蛍光ランプ102とは他面側の照明器具本体101の上面に配置され、光不透過性のつば部202aで囲まれているため、開口部201から入射し赤外線反射伝達材105を介して開口部202から出射する赤外線信号のみを受光する。   The light receiving element 104 is disposed on the upper surface of the luminaire main body 101 on the other side of the fluorescent lamp 102 and is surrounded by a light-impermeable collar 202a. Only the infrared signal emitted from the opening 202 through 105 is received.

また、外周側面3箇所の開口部201に蛍光ランプ102からの直接光および、照明器具グローブ103の内面での反射光が入射されないように、開口部201付近の椀型の照明器具グローブ103の外周縁には、遮光シート110が取り付けられている。   In addition, the direct light from the fluorescent lamp 102 and the reflected light from the inner surface of the lighting fixture globe 103 are not incident on the openings 201 at the three outer peripheral side surfaces. A light shielding sheet 110 is attached to the periphery.

さらに、開口部201の上部に突設されたつば部201aにより、赤外線リモコン(図示無し)から赤外線反射伝達材105に入射する赤外線信号の入射効率を向上させるとともに、天井面106による蛍光ランプ102の反射光が開口部201へ入射されるのを防いでいる。   Further, the flange portion 201a protruding from the upper portion of the opening 201 improves the incident efficiency of the infrared signal incident on the infrared reflection transmission material 105 from the infrared remote controller (not shown), and the fluorescent lamp 102 by the ceiling surface 106 is improved. The reflected light is prevented from entering the opening 201.

このような構成により、受光素子104および開口部201に蛍光ランプ102による光ノイズが入射されず、赤外線リモコン(図示無し)から送信された赤外線信号のみが開口部201に入射され、赤外線反射伝達材105内で反射を繰り返した後、開口部202を介して受光素子104へ到達するため、蛍光ランプ102の光ノイズの影響を受けることなく受信感度が確保され、点灯装置108の誤動作や不動作を防止している。   With such a configuration, light noise due to the fluorescent lamp 102 is not incident on the light receiving element 104 and the opening 201, and only an infrared signal transmitted from an infrared remote controller (not shown) is incident on the opening 201, and an infrared reflection transmission material. After being repeatedly reflected in 105, the light reaches the light receiving element 104 through the opening 202, so that reception sensitivity is ensured without being affected by the light noise of the fluorescent lamp 102, and malfunction or malfunction of the lighting device 108 is prevented. It is preventing.

また、赤外線反射伝達材105の外周側面の開口部201を120度間隔で3箇所設けることにより、全方向からの赤外線信号に対応することが可能となっている。   Further, by providing three openings 201 on the outer peripheral side surface of the infrared reflection transmitting material 105 at intervals of 120 degrees, it is possible to cope with infrared signals from all directions.

また、受光素子104と赤外線反射伝達材105を、照明器具本体101の上面という下方から見た場合に外観上から隠れた部分に配置されているので、照明器具グローブ103に受光素子104や赤外線反射伝達材105の陰影が写ることによるランプイメージの悪化がない。さらには、照明器具本体101および照明器具グローブ103の大きさを蛍光ランプ102に対して過度に大きくする必要がない。さらに、照明器具グローブ103に赤外線を通過させる必要がないため、照明器具グローブ103の形状や材質、デザインの自由度が向上する。   In addition, since the light receiving element 104 and the infrared reflection transmission material 105 are arranged in a portion hidden from the appearance when viewed from the lower side of the upper surface of the luminaire main body 101, the light receiving element 104 and the infrared reflection There is no deterioration of the lamp image due to the shadow of the transmission material 105. Furthermore, it is not necessary to make the size of the lighting fixture body 101 and the lighting fixture globe 103 excessively larger than the fluorescent lamp 102. Furthermore, since it is not necessary to allow infrared rays to pass through the lighting fixture globe 103, the shape, material, and design freedom of the lighting fixture globe 103 are improved.

なお、開口部201には、上部から突出したつば部201aを設けるとともに、開口部201の側部からもつば部(図示無し)を外側へ突設してもよい。   The opening 201 may be provided with a flange portion 201a protruding from the upper portion, and a flange portion (not shown) protruding from the side portion of the opening portion 201 may be provided outward.
