Description

この発明は、可視光型光触媒を利用した空気浄化機能を有する建築化照明システムに関する。   The present invention relates to an architectural lighting system having an air purification function using a visible light type photocatalyst.

住宅における高断熱高気密化は、省エネルギー性及び室内の温熱環境の向上をもたらしている。しかし、その一方で、内装材や家具等に使用されている接着剤や塗料等から放出されるホルムアルデヒド等の揮発性有機化合物(VOC)が室内に滞留し易くなって、頭痛、めまい、吐き気等の体の変調をきたす、いわゆるシックハウス症候群(化学物質過敏症)が問題になっている。   High heat insulation and high airtightness in houses have brought about energy saving and improvement of indoor thermal environment. However, on the other hand, volatile organic compounds (VOC) such as formaldehyde released from adhesives and paints used in interior materials and furniture, etc. tend to stay in the room, causing headache, dizziness, nausea, etc. So-called sick house syndrome (chemical hypersensitivity), which causes the body's body modulation, has become a problem.

このため、室内の空気を浄化するための空気清浄機が各種市販されている。例えば、活性炭等の吸着材を用いて有機化合物を吸着するものや、ブラックライトと紫外光型光触媒を用いて有機化合物を分解するものがある。   For this reason, various air purifiers for purifying indoor air are commercially available. For example, there are those that adsorb organic compounds using an adsorbent such as activated carbon, and those that decompose organic compounds using black light and an ultraviolet light photocatalyst.

しかしながら、このような空気清浄機は、一般に据え置き型のものが多く、室内空気の局部的な浄化には適しているが、室内空気を全体的に効率良く浄化するには不向きであった。また、活性炭等の吸着材を使用した場合には、定期的に吸着材の交換が必要となり、ブラックライトを使用した場合には、電気代が嵩むといったように、ランニングコストが必要であった。   However, such air purifiers are generally stationary types and are suitable for local purification of indoor air, but are unsuitable for efficiently purifying indoor air as a whole. Further, when an adsorbent such as activated carbon is used, it is necessary to periodically exchange the adsorbent, and when black light is used, a running cost is required, such as an increase in electricity bill.

一方、近年においては、紫外線の照射により反応するだけでなく、蛍光灯や白熱灯、ハロゲンランプといった一般的な照明用光源からの可視光によっても触媒活性を発揮する可視光型光触媒が各種開発されている。そして、このような可視光型光触媒を室内の壁や天井にコーティングしたり(例えば特許文献1、特許文献2)、さらには可視光型光触媒を照明器具に担持させて(例えば特許文献3)、照明用光源からの可視光を可視光型光触媒に照射させることで、ランニングコストを抑えながら室内空気を浄化するシステムが提案されている。   On the other hand, in recent years, various types of visible light photocatalysts have been developed that not only react by irradiation with ultraviolet rays but also exhibit catalytic activity by visible light from general lighting sources such as fluorescent lamps, incandescent lamps, and halogen lamps. ing. And such a visible light type photocatalyst is coated on an indoor wall or ceiling (for example, Patent Document 1, Patent Document 2), and further, a visible light type photocatalyst is carried on a lighting device (for example, Patent Document 3), There has been proposed a system that purifies indoor air while reducing running costs by irradiating visible light type photocatalyst with visible light from an illumination light source.

しかしながら、室内の壁に可視光型光触媒をコーティングする場合には、室内に設置した家具等によって照明用光源からの可視光が面的に遮られることが多い。また、室内の天井に可視光型光触媒をコーティングする場合には、一般に照明用光源からの可視光は室内空間に向けて照射されるので、照明器具から離れた壁際等においては可視光が当たり難くなる。   However, when the indoor wall is coated with a visible light type photocatalyst, visible light from the illumination light source is often obstructed by furniture installed indoors. Further, when a visible light photocatalyst is coated on the ceiling of the room, the visible light from the illumination light source is generally directed toward the indoor space, so that it is difficult for the visible light to hit the wall away from the lighting fixture. Become.

従って、室内の壁や天井に可視光型光触媒を単にコーティングしただけでは、照明用光源からの可視光が十分に照射されない箇所が生じることが多く、そのような箇所にコーティングした可視光型光触媒が無駄になって、室内空気の浄化効率が悪くなるといった不具合があった。   Therefore, simply coating a visible light type photocatalyst on an indoor wall or ceiling often results in locations where the visible light from the illumination light source is not sufficiently irradiated. There was a problem that it was wasted and the efficiency of purifying indoor air deteriorated.

一方、照明器具に可視光型光触媒を担持させる場合には、照明用光源からの可視光を可視光型光触媒に対して良好に照射させることができるが、室内の壁や天井に可視光型光触媒をコーティングする場合と比べて、可視光型光触媒領域が狭くなる。光触媒の反応速度は決して速くないため、室内空気を全体的に効率良く浄化するためには、空気との接触面積をある程度広く確保する必要があるが、照明器具に可視光型光触媒を担持させるだけでは十分な浄化効果を期待することはできないといった不具合があった。   On the other hand, when a visible light type photocatalyst is carried on a lighting fixture, visible light from a light source for illumination can be satisfactorily irradiated to the visible light type photocatalyst. Compared with the case of coating, the visible light photocatalytic region becomes narrower. Since the reaction rate of the photocatalyst is never high, in order to purify indoor air as a whole efficiently, it is necessary to secure a certain contact area with the air, but only the visible light type photocatalyst is supported on the lighting fixture. However, there was a problem that a sufficient purification effect could not be expected.

そこで、この発明は、上記不具合を解消して、ランニングコストを抑えながら、室内空気を全体的に効率良く浄化することができる空気浄化機能を有する建築化照明システムの提供を目的とする。   Accordingly, an object of the present invention is to provide an architectural lighting system having an air purification function that can eliminate the above-described problems and purify indoor air efficiently while reducing running costs.

上記課題を解決するため、この発明の空気浄化機能を有する建築化照明システムは、照明用光源4を遮蔽部材2、21、31、41により覆い隠して、前記照明用光源4からの可視光を、室内の天井1又は壁6、及び、前記遮蔽部材2、21、31、41において反射させて、室内を間接的に照明するものあって、可視光の照射により活性を有する可視光型光触媒領域10、22、32、42を、前記室内の天井1又は壁6、前記遮蔽部材2、21、31、41における光反射部位に設けたことを特徴とする。   In order to solve the above-described problems, an architectural lighting system having an air purification function according to the present invention covers the illumination light source 4 with the shielding members 2, 21, 31, and 41, and allows visible light from the illumination light source 4 to be covered. A visible light type photocatalytic region which is reflected by the indoor ceiling 1 or wall 6 and the shielding members 2, 21, 31, 41 and indirectly illuminates the room and which is active by irradiation with visible light. 10, 22, 32, and 42 are provided in the light reflection portion of the indoor ceiling 1 or wall 6 and the shielding members 2, 21, 31, and 41.

また、前記可視光型光触媒領域10、22、32、42付近の空気を強制的に流動させるための送風機11を設けている。   Further, a blower 11 for forcibly flowing the air in the vicinity of the visible light type photocatalyst regions 10, 22, 32, 42 is provided.

具体的には、室内の天井1の下方に、前記遮蔽部材としての天井板材2・・を配設するとともに、前記室内の天井1と天井板材2・・との間の空間3に前記照明用光源4・・を配置して、前記可視光型光触媒領域10を、前記室内の天井1又は壁6、天井板材2・・における光反射部位に設けている。   Specifically, a ceiling plate material 2... As the shielding member is disposed below the indoor ceiling 1, and the lighting 3 is provided in the space 3 between the indoor ceiling 1 and the ceiling plate material 2. The visible light type photocatalyst region 10 is provided in the light reflecting portion of the indoor ceiling 1 or wall 6 and the ceiling plate material 2.

また、前記可視光型光触媒領域10付近の空気を強制的に流動させるための送風機11を、前記天井板材2・・により覆い隠すようにして、前記室内の天井1又は天井板材2・・に取り付けている。   Further, a blower 11 for forcibly flowing the air in the vicinity of the visible light type photocatalyst region 10 is attached to the indoor ceiling 1 or the ceiling plate material 2 so as to be covered by the ceiling plate material 2. ing.

さらに、前記室内の天井1と天井板材2・・との間の空間3と、前記天井板材2・・の下方の室内空間とを連通する通気用の空隙8、12を設けている。   Furthermore, air gaps 8 and 12 are provided for communicating the space 3 between the ceiling 1 and the ceiling plate material 2... And the indoor space below the ceiling plate material 2.

この発明の建築化照明システムにおいては、間接照明を採用して、照明用光源からの可視光を反射する光反射部位に可視光型光触媒領域を設けているから、比較的広い範囲の可視光型光触媒領域に対して可視光を直接且つ確実に照射することができ、これによって室内空気を全体的に効率良く浄化することができる。   In the structured lighting system of the present invention, the visible light type photocatalyst region is provided in the light reflecting portion that reflects the visible light from the illumination light source by employing indirect lighting, so that the visible light type in a relatively wide range is provided. Visible light can be directly and reliably radiated to the photocatalyst region, whereby the indoor air can be purified efficiently as a whole.

しかも、照明用光源の点灯による日常的な照明に際して、同時に空気浄化を行うことができるため、ランニングコストを低く抑えることができる。   In addition, the running cost can be kept low because air purification can be performed at the same time during routine illumination by turning on the illumination light source.

また、可視光型光触媒領域付近の空気を送風機によって強制的に流動させることで、室内空気を可視光型光触媒領域へ効率良く接触させることができ、これによって室内空気の浄化効率を高めることができる。さらに、照明用光源や送風機を覆い隠すことで、見栄えの良好なデザインされた建築化照明において空気浄化を実現することができる。   Further, the air in the vicinity of the visible light type photocatalyst region is forced to flow by the blower, so that the indoor air can be efficiently brought into contact with the visible light type photocatalyst region, thereby improving the purification efficiency of the indoor air. . Furthermore, by covering the illumination light source and the blower, it is possible to achieve air purification in the architectural lighting designed to look good.

この発明の実施形態について、図面を参照しつつ詳細に説明する。この発明の一実施形態に係る建築化照明システムは、図1及び図2に示すように、住宅における室内の天井1の下方に複数の天井板材2・・を略水平に吊り下げ支持して二重天井を構成し、この二重天井の内部空間すなわち室内の天井1と天井板材2・・との間の空間3に、照明用光源4・・を配置している。そして、照明用光源4・・からの可視光を、室内の天井1及び天井板材2・・の上面において反射させて、室内を間接的に照明するようになっている。   Embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, an architectural lighting system according to an embodiment of the present invention includes a plurality of ceiling plate members 2.. A heavy ceiling is formed, and an illumination light source 4 is arranged in the internal space of the double ceiling, that is, the space 3 between the indoor ceiling 1 and the ceiling plate material 2. Then, the visible light from the illumination light source 4... Is reflected on the upper surface of the indoor ceiling 1 and the ceiling plate material 2.

天井板材2・・は、略方形状に形成された鋼板からなり、縦方向及び横方向に並設されて、それら天井板材2・・間には縦方向及び横方向に沿ったスリット5・・が形成されている。また、外側の天井板材2・・と室内の壁6との間には、隙間7・・が形成されている。そして、これらスリット5・・及び隙間7が、空間3と天井板材2・・の下方の室内空間とを連通する通気用及び透光用の空隙8とされている。   The ceiling plate 2 is made of steel plates formed in a substantially rectangular shape, and is arranged side by side in the vertical and horizontal directions, and the slits 5 along the vertical and horizontal directions are arranged between the ceiling plates 2. Is formed. Further, a gap 7 is formed between the outer ceiling plate material 2 and the indoor wall 6. The slits 5... And the gap 7 serve as a ventilation 8 and a translucent space 8 that connect the space 3 and the indoor space below the ceiling plate material 2.

照明用光源4・・としては、可視光を照射する蛍光灯が用いられているが、可視光を照射するものであれば、白熱灯やハロゲン灯等のその他のインテリア照明用光源を用いても良い。この照明用光源4・・は、遮蔽部材としての複数の天井板材2・・によって覆い隠された状態で、天井板材2・・の上面に取り付けられている。   A fluorescent lamp that emits visible light is used as the illumination light source 4..., But other interior illumination light sources such as incandescent lamps and halogen lamps may be used as long as they emit visible light. good. The illumination light sources 4 are attached to the upper surface of the ceiling plate material 2 in a state of being covered with a plurality of ceiling plate materials 2 as a shielding member.

そして、この建築化照明システムにおいては、図2に示すように、例えば2000〜3000ルクスといった照度が得られる室内の天井1及び壁6の光反射部位、及び天井板材2・・の上面である光反射部位に、可視光の照射により活性を有する可視光型光触媒がコーティングされて、可視光型光触媒領域10が設けられている。   In this architectural lighting system, as shown in FIG. 2, the light that is the upper surface of the ceiling 1 and the wall 6 of the indoor ceiling 1 and the wall 6, for example, an illuminance of 2000 to 3000 lux is obtained. A visible light photocatalyst region 10 is provided on the reflective portion by coating the visible light photocatalyst having activity by irradiation with visible light.

さらに、この可視光型光触媒領域10と室内空気との接触機会を増やして、室内空気の浄化効率を高めるために、可視光型光触媒領域10付近の空気を強制的に流動させるための送風機11が、天井板材2・・により覆い隠された状態で天井板材2・・の上面に取り付けられている。そして、送風機11が取り付けられた天井板材2には、通気用の空隙を確保するガラリ12が形成されている。なお、この送風機11は、天井板材2・・の上面に取り付けるだけでなく、室内の天井1に取り付けるようにしても良い。   Furthermore, in order to increase the contact opportunity of this visible light type photocatalyst area | region 10 and room air, and to improve the purification efficiency of indoor air, the air blower 11 for forcedly flowing the air of visible light type photocatalyst area | region 10 is provided. Are attached to the upper surface of the ceiling plate material 2 in a state of being covered with the ceiling plate material 2. And the gallery 12 which ensures the space | gap for ventilation | gas_flowing is formed in the ceiling board | plate material 2 to which the air blower 11 was attached. The blower 11 may be attached not only to the upper surface of the ceiling plate 2... But also to the indoor ceiling 1.

上記構成の建築化照明システムにおいて、照明用光源4・・を点灯させると、図2に示すように、照明用光源4・・からの可視光が、室内の天井1及び壁6、天井板材2・・の上面において反射を繰り返して、空隙8から天井板材2・・の下方の室内空間へ向けて照射する。   In the structured illumination system having the above-described configuration, when the illumination light sources 4 are turned on, the visible light from the illumination light sources 4 is converted into the indoor ceiling 1 and walls 6 and the ceiling plate 2 as shown in FIG. ... Repeated reflection on the upper surface of the irradiating light from the gap 8 toward the indoor space below the ceiling plate 2.

このとき、室内の天井1及び壁6、天井板材2の光反射部位には、可視光型光触媒領域10・・が設けられているので、可視光下で強い触媒活性を発揮し、この可視光型光触媒領域10に空間3内の空気が接触することで、空間3内の空気に含まれる有害な有機化合物が分解除去され、また脱臭される。ここで、空間3内に設けた送風機11を作動させることで、空間3内の空気が撹拌されて、可視光型光触媒領域10への空間3内の空気の接触機会が増え、これによって空間3内の空気の浄化が促進される。   At this time, since the visible light type photocatalytic region 10 is provided in the light reflection part of the ceiling 1 and the wall 6 and the ceiling plate material 2 in the room, the visible light exhibits a strong catalytic activity under visible light. When the air in the space 3 comes into contact with the type photocatalyst region 10, harmful organic compounds contained in the air in the space 3 are decomposed and deodorized. Here, by operating the blower 11 provided in the space 3, the air in the space 3 is agitated, and the opportunity of contact of the air in the space 3 with the visible light photocatalyst region 10 is increased. The purification of the air inside is promoted.

浄化後の空間3内の空気は、ガラリ12から天井板材2・・の下方の室内空間へ向けて送り出され、代わりに天井板材2・・の下方の室内空気が空隙8から空間3内に流れ込んで、可視光型光触媒領域10に接触することで浄化される。そして、このような空気循環が繰り返されることで、室内空間全体の空気が効率良く浄化される。   The air in the space 3 after purification is sent out from the louver 12 toward the indoor space below the ceiling plate material 2... Instead, the indoor air below the ceiling plate material 2. Thus, the contact with the visible light photocatalyst region 10 is purified. And the air of the whole indoor space is efficiently purified by repeating such air circulation.

図3は、他の実施形態に係る建築化照明システムを示している。この建築化照明システムは、コーブ照明を採用しており、室内の壁6に沿って設けた上面開放の収容空間20内に照明用光源4が収容されている。   FIG. 3 shows an architectural lighting system according to another embodiment. This architectural lighting system employs cove illumination, and the illumination light source 4 is accommodated in an accommodation space 20 that is open along the wall 6 in the room.

収容空間20は、長押やカーテンボックス等を利用して形成されたもので、室内の壁6とこの壁6から突出した略L型の遮蔽部材21によって囲まれた空間であり、この収容空間20に収容された照明用光源4は、遮蔽部材21により覆い隠されている。そして、この照明用光源4からの可視光を、室内の天井1、壁6上部及び遮蔽部材21において反射させて、室内を間接的に照明するようになっている。   The accommodation space 20 is formed using a long press, a curtain box, or the like, and is a space surrounded by the indoor wall 6 and a substantially L-shaped shielding member 21 protruding from the wall 6. The illumination light source 4 housed in is covered with a shielding member 21. The visible light from the illumination light source 4 is reflected by the ceiling 1 of the room, the upper part of the wall 6 and the shielding member 21 to indirectly illuminate the room.

この建築化照明システムにおいても、例えば2000〜3000ルクスといった照度が得られる室内の天井1及び壁6上部の光反射部位、さらには遮蔽部材21の内面である光反射部位に、可視光型光触媒がコーティングされて、可視光型光触媒領域22が設けられている。   Also in this architectural lighting system, a visible light photocatalyst is applied to a light reflecting portion on the ceiling 1 and the upper portion of the wall 6 where the illuminance can be obtained, for example, 2000 to 3000 lux, and further to a light reflecting portion that is an inner surface of the shielding member 21.

Here, for example, if the blower 11 is provided on the ceiling 1 or the like and the air near the visible light photocatalyst region 22 is forced to flow, the chance of indoor air contact with the visible light photocatalyst region 22 increases. This promotes purification of room air.

A visible light photocatalytic region 32 is provided by coating.

従って、照明用光源4からの可視光が照射された可視光型光触媒領域32に室内空気が接触することで、室内空気に含まれる有害な有機化合物が分解除去され、また脱臭される。ここで、例えば天井1等に送風機11を設けて、可視光型光触媒領域32付近の空気を強制的に流動させるようにすれば、可視光型光触媒領域32への室内空気の接触機会が増え、これによって室内空気の浄化が促進される。なお、その他の構成は、上記実施形態と同様であり、上記実施形態と同様の機能を有する部材については同符号を付してある。   Accordingly, when the room air comes into contact with the visible light photocatalyst region 32 irradiated with visible light from the illumination light source 4, harmful organic compounds contained in the room air are decomposed and deodorized. Here, for example, if the blower 11 is provided on the ceiling 1 or the like and the air near the visible light photocatalyst region 32 is forced to flow, the chance of indoor air contact with the visible light photocatalyst region 32 increases. This promotes purification of room air.
