Abstract
Description
この発明は、反射効率を向上させた反射板の構造に関する。 The present invention relates to the structure of a reflector with improved reflection efficiency.
従来より、照明器具その他において、反射機能を有する反射板が多用されているが、本発明にて示すように、発光体の直上に段部状斜面部を設けたものは見当たらない。 Conventionally, a reflector having a reflective function is often used in lighting equipment and the like, but as shown in the present invention, there is no one in which a stepped slope portion is provided directly above the light emitting body.
発光体は、以前より天井照明、懐中電灯、自動車のヘッドライト、ヒーター式ストーブ、照射式の融雪装置など多方面に利用されており、通常はその発光体から放射される光や熱線を効率よく利用するために、反射板が用いられている。
この反射板の形状は様々であるが、その一例としては放物面型反射板がある。
これは放物面の焦点位置に発光体を位置させることによって、この発光体からの放射光や放射熱線を平行に前方外部へ照射するという性質を有して、特定方向への照射を行うことができる。
円柱形の発光体、例えば蛍光灯ではその発光体の直上の反射板はゆるやかなカーブ面であるために、蛍光灯から直上方向へ発した光は反射にてまた蛍光灯外面にもどるために、この箇所の光は有効活用できないという問題があり、これは遠赤外線その他の発光体の反射板でも同様である。
本発明は以上に鑑み、この直上方向への光や熱線を有効活用するための新規かつ有用なる反射板構造を得ることを目的として発明されたものである。Light emitters have long been used in various fields such as ceiling lighting, flashlights, automobile headlights, heater-type stoves, and irradiation-type snow melting devices, and normally efficiently emit light and heat rays from the light emitters. A reflector is used for use.
The shape of this reflector varies, and one example is a parabolic reflector.
This has the property of irradiating the synchrotron radiation and radiant heat rays from the synchrotron radiation to the front and outside in parallel by locating the illuminant at the focal position of the paraboloid, and irradiates in a specific direction. Can be done.
In a cylindrical light emitter, for example, in a fluorescent lamp, the reflector directly above the light emitter has a gently curved surface, so that the light emitted from the fluorescent lamp in the direct upward direction is reflected and returned to the outer surface of the fluorescent lamp. There is a problem that the light in this part cannot be effectively used, and this also applies to the reflector of far infrared rays and other light emitters.
In view of the above, the present invention has been invented for the purpose of obtaining a novel and useful reflector structure for effectively utilizing the light and heat rays in the direction directly above.
課題を解決する手段として本発明は以下の構成とした。
すなわち、内部に発光体を位置させた反射板において、該反射板の一部に段部状斜面部を形成する。本発明は以上の構成よりなる反射効率向上型反射板構造である。The present invention has the following configuration as a means for solving the problem.
That is, in a reflector in which a light emitting body is positioned inside, a stepped slope portion is formed in a part of the reflector. The present invention is a reflector structure with improved reflection efficiency having the above configuration.
本発明によれば、発光体に近接して段部状斜面部が位置するので、発光体直上にこの斜面部を位置させることにより、発光体最上部および最上部近傍からの放射光を、この斜面部にて反射し、この反射光は反射板内面にて反射をくり返すことで外部へと放射され、従来法に比べてより効率のよい反射光利用を可能とする、有意な反射板構造を得ることができる。また、可視光線のみならず遠赤外線など他の波長にても有効に活用することができる。 According to the present invention, since the stepped slope portion is located close to the light emitting body, by locating this slope portion directly above the light emitting body, the emitted light from the uppermost portion of the light emitting body and the vicinity of the uppermost portion can be emitted. It is reflected on the slope, and this reflected light is radiated to the outside by repeating the reflection on the inner surface of the reflector, which enables more efficient use of the reflected light compared to the conventional method. Can be obtained. Moreover, it can be effectively used not only for visible light but also for other wavelengths such as far infrared rays.
以下、本発明の実施形態について説明する。これは、遠赤外線放射型の融雪装置の例である。図において、１はケーシングで、側面視において上部をすぼめた下部開放直方体形状の箱体である。２は反射板で、高反射率を有する特定形状の金属板である。
その形状は図２にて示すように、側面視においてその上部は段部状斜面部３が形成され、その近傍は放物面状に形成された放物面部が設けられでいる。また、この反射板は正面視において、図３にて示すように、略台形状である。上記放物面部の焦点位置には、円柱状の遠赤外線放射ランプ４が適宜支持部材にて支持されて位置している。なお、図示を略したが，端子台その他の必要部品が装備され、このランプは通電接続される。Hereinafter, embodiments of the present invention will be described. This is an example of a far-infrared radiation type snow melting device. In the figure, reference numeral 1 denotes a casing, which is a box body in the shape of a rectangular parallelepiped with an open lower part having a pursed upper part in a side view.
As shown in FIG. 2, the shape is such that a stepped
次に、本発明による反射板と従来例の反射板との違いについて説明する。
図１は従来例、図２は本発明の例である。
まず、従来例では反射板は放物面形状を有して、その焦点位置に発光体もしくはヒーターが位置している。発光体から放射された光は図の二点鎖線にて示すように反射板に当たって反射し、放物面の性質にて下方外方へと放射される。
しかし、この発光体の最上部および最上部近傍から上方へ向けて放射された光は、反射板にて反射されるが、この反射光は再び発光体へともどって外部への放射とはならない。
つまり、放物面の上部（底部）はゆるやかな湾曲面となっているために，このような現象となるのである。Next, the difference between the reflector according to the present invention and the conventional reflector will be described.
FIG. 1 is a conventional example, and FIG. 2 is an example of the present invention.
First, in the conventional example, the reflector has a parabolic shape, and a light emitter or a heater is located at the focal position thereof. The light emitted from the illuminant hits the reflector and is reflected as shown by the alternate long and short dash line in the figure, and is radiated downward and outward due to the nature of the paraboloid.
However, the light radiated upward from the uppermost part of the illuminant and the vicinity of the uppermost part is reflected by the reflector, but the reflected light returns to the illuminant and does not radiate to the outside. ..
In other words, this phenomenon occurs because the upper part (bottom) of the paraboloid is a gently curved surface.
すなわち、電磁波の一種である可視光線および可視光線に近い波長の電磁波は直進性を有し、波長が短くなるにつれてその直進性が顕著になるためである。
一方、本発明の反射板は、既述のごとく発光体直上に段部状斜面部を有している。
この段部の頂点は発光体の中央直上の位置にあり、段部頂点から振り分けにて上向きの斜面部が形成され、その上向き斜面部の最上位置は側面視において、発光体の側面よりやや外側の位置にある。
従って、図２にて示すように、発光体の直上および直上近傍から放射された上向きの光は図のごとく反射をくり返してやがて下方へ向かう光となって外部へと放射される。
ゆえに従来例のような非利用の光や熱線は発生せず、放射されたすべての光を有効に活用することができる。That is, visible light, which is a kind of electromagnetic wave, and electromagnetic waves having a wavelength close to visible light have straightness, and the straightness becomes more remarkable as the wavelength becomes shorter.
On the other hand, the reflector of the present invention has a stepped slope portion directly above the light emitting body as described above.
The apex of this step is located directly above the center of the illuminant, and an upward slope is formed by sorting from the apex of the step, and the uppermost position of the upward slope is slightly outside the side surface of the illuminant in side view. It is in the position of.
Therefore, as shown in FIG. 2, the upward light radiated from directly above and near the illuminant is repeatedly reflected as shown in the figure, and eventually becomes downward light and is radiated to the outside.
Therefore, unused light and heat rays as in the conventional example are not generated, and all the emitted light can be effectively utilized.
以上、本発明について記したが、本発明に用いた段部状斜面部にて、発光体からの放射光や放射熱線をこの斜面部にて反射させることにて、既述のように放射光等をすべて有効活用することができる。
本方式は、直進性を有する電磁波のすべてにおいて利用可能であり、可視光線、遠赤外線、紫外線灯にも有効である。可視光線用では、蛍光灯を用いた照明器具に利用でき、遠赤外線用では、ヒーターを用いた反射型ストーブや暖房機への利用、さらに遠赤外線方式の融雪装置への活用も実証されている。紫外線には殺菌能力があるため、殺菌灯への利用が見込まれる。近年、進展のある分野の一つとして、特定波長・特定光色の光を用いた屋内型水耕栽培への利用も可能と思われる。
以上のごとく、本発明による方式は多方面への利用が可能であり、省エネルギー的構成物として，従来にない有用性を得ることができる。The present invention has been described above, but the stepped slope portion used in the present invention reflects the synchrotron radiation and the radiated heat rays from the illuminant on this slope portion, so that the synchrotron radiation is as described above. Etc. can all be used effectively.
This method can be used for all electromagnetic waves having straightness, and is also effective for visible light, far infrared rays, and ultraviolet lamps. For visible light, it can be used for lighting equipment using fluorescent lamps, and for far-infrared light, it has been proven to be used for reflective stoves and heaters that use heaters, and for far-infrared snow melting equipment. .. Since ultraviolet rays have a bactericidal ability, they are expected to be used as germicidal lamps. In recent years, as one of the fields with progress, it seems that it can be used for indoor hydroponics using light of a specific wavelength and a specific light color.
As described above, the method according to the present invention can be used in various fields, and as an energy-saving component, it is possible to obtain unprecedented usefulness.
