Description
本考案は、蛍光灯やLED蛍光灯が合成樹脂製のパイプの光拡散性により、光源の陰り(ホットスポット)を見せない状態で、より明るく光源の照明を提供するためのランプシェードとホットスポットが見えても、より十分に光を透過させて照明させるランプシェードの両方に関する。The present invention is a lamp shade and hot spot for providing brighter light source illumination in a state where the fluorescent lamp and the LED fluorescent lamp do not show the shade (hot spot) of the light source due to the light diffusibility of the pipe made of synthetic resin. This relates to both lamp shades that allow even more light to pass through and illuminate.
近年、地球温暖化の問題がますます、クローズアップし、温室効果ガスの中心である二酸化炭素の排出量削減、省エネルギーの推進が大きいテーマになっている。照明器具も消費電力がより少なく、二酸化炭素を排出しない環境に優しい方向に進んでいます。白熱電球は電球型蛍光灯へ転換し、さらに、LED蛍光灯へ急激に進もうとしています。従来、最大の問題であったLEDの高価格が今後、どの程度、コストダウンが図られるかが、LED普及のキーポイントになっている。同時に、1990年の京都議定書を起点として、2008年7月の洞爺湖サミットでの国際的な各種温暖化対策と同年秋よりの温室効果ガスの排出量取引の施行により、LED信号の普及と同様に、照明のLED化が急進展する状況になってきた。In recent years, the issue of global warming has become more and more close-up, and reduction of carbon dioxide emissions, which is the center of greenhouse gases, and promotion of energy saving have become major themes. Lighting fixtures are also consuming less energy and are moving in an environmentally friendly way that does not emit carbon dioxide. Incandescent light bulbs are changing to light bulb-type fluorescent lamps, and they are rapidly moving toward LED fluorescent lamps. The key point for the spread of LEDs is how much the high cost of LEDs, which has been the biggest problem in the past, will be reduced in the future. At the same time, starting from the Kyoto Protocol in 1990, the global warming countermeasures at the Toyako Summit in July 2008, and greenhouse gas emissions trading from the fall of the same year will be implemented, as will the spread of LED signals In addition, the use of LED lighting has been rapidly progressing.
本考案は、従来蛍光灯より約50%以上、消費電力を節約し、5倍以上の寿命を持つLED蛍光灯を用途別に要求されるニーズに対応したガラスより、はるかに強度のあるパイプ状ランプシェートを提案し、より適切なLED蛍光灯を開発することにある。このランプシェードは、従来蛍光灯にも応用できると考える。直管型LED蛍光灯は、コンビニエンスストアーやオフィスビル等の照明に使用される可能性があるが、LEDのランプは眩しく、直接、ランプの光を見ることは眼に良くないため、蛍光灯の笠であるランプシェードは従来の蛍光灯と同じように乳白色が最良である。しかし、ランプの光源ををランプシェードを通して、下方向120°程度の方位に照明するためには、光拡散性が良く、強度のあるランプシェードが求められる。同時に、ランプシェードの下からランプの形が見えたり、ホットスポットが見えない商品価値のあるランプシェードが求められる。一方、スーパーマーケットやコンビニエンスストアーの冷蔵・冷凍ショーケースや自動販売機等は、ランプの光源を人が見る位置にないため、むしろ、光線透過が優れていれば良い用途である。すなわち、LED蛍光灯は使い方によって、そのランプシェードに対する要求事項が異なり、これらの各種ニーズに対応できるランプシェードが求められている。The present invention saves about 50% more power than conventional fluorescent lamps, and LED lamps with a lifespan more than five times longer than pipes that meet the needs required for each application. To develop a more appropriate LED fluorescent lamp. This lamp shade is considered to be applicable to conventional fluorescent lamps. Although straight tube type LED fluorescent lamps may be used for lighting in convenience stores, office buildings, etc., LED lamps are dazzling, and it is not good for the eyes to see the light of the lamps directly. The lamp shade, which is a shade, is milky white as is the case with conventional fluorescent lamps. However, in order to illuminate the light source of the lamp through the lamp shade in the downward direction of about 120 °, a lamp shade having good light diffusibility and strength is required. At the same time, there is a demand for a lamp shade with a commercial value in which the shape of the lamp can be seen from under the lamp shade and the hot spot cannot be seen. On the other hand, refrigerated / frozen showcases, vending machines, etc. in supermarkets and convenience stores are rather applications where light transmission is excellent because the light source of the lamp is not in a position for human viewing. That is, LED fluorescent lamps have different requirements for their lamp shades depending on how they are used, and there is a need for lamp shades that can meet these various needs.
本考案は、以上のような課題を解決するために、異なる二色・二種類の樹脂を原料として、一式の二色成形金型で同時に一体成形したランプシェードを作成する。
原料は光拡散性を付与した乳白色と透明のポリカーボネート樹脂かアクリル樹脂を用意する。まず、コンビニエンスストアーやオフィスビル等の照明に使用するLED蛍光灯は、120°の光拡散性を有した乳白色のポリカーボネート樹脂をパイプの図3 2に切れ込み溝を持ったパイプを押出成形する。
二色成形金型では、二台の押出機により、同一の光拡散性を有した乳白色の樹脂を押出加工し、結果として、パンプ全体が均一で強度のある光拡散ランプシェードができる。図3 2の切れ込み溝には、LEDランプ図3 4を適切な距離の一定間隔にセットした基盤図3 3を下部に取り付けたLEDの発熱を逃がすためのアルミニウム製放熱板図3 2を嵌合させる。In order to solve the above-described problems, the present invention creates a lamp shade that is integrally molded simultaneously with a set of two-color molding dies using different two-color and two-type resins as raw materials.
As the raw material, milky white and transparent polycarbonate resin or acrylic resin provided with light diffusibility are prepared. First, for LED fluorescent lamps used for lighting in convenience stores, office buildings, etc., a milky white polycarbonate resin having 120 ° light diffusibility is extruded into a pipe having a slit in FIG. 32 of the pipe.
In the two-color molding die, milky white resin having the same light diffusibility is extruded by two extruders. As a result, a light diffusion lampshade having a uniform and strong entire pump can be obtained. In the slit groove of FIG. 32, an LED lamp FIG. 34 is set at a fixed interval of an appropriate distance. FIG. 32 is fitted with an aluminum heatsink FIG. Let
次に、ランプシェード図3 1−3に、透明ないし白色半透明の光拡散ポリカーボネート樹脂を成形し、それに隣接するランプシェード図3 1−2乳白色の光拡散ポリカーボネート樹脂で、同時に、一体二色成形される。その上部天面、図3 2の切れ込み溝には、LEDランプを適切な距離の一定間隔にセットした基盤を下部に取り付けたLEDの発熱を逃がすためのアルミニウム製放熱板を嵌合させる。Next, a transparent or white translucent light diffusing polycarbonate resin is formed on the lamp shade, Fig. 31-3, and the lamp shade Fig. 3 1-2 milky white light diffusing polycarbonate resin is formed at the same time. Is done. The upper top surface, the cut groove in FIG. 32, is fitted with an aluminum heat sink for releasing the heat generated by the LED with the base on which the LED lamps are set at regular intervals at an appropriate distance.
前記の0004の乳白色の光拡散パイプ状ランプシェードは、LED蛍光灯の下方からランプの形が見えず、ホットスポットが見えないLED蛍光灯が実現できる。このタイプのLED蛍光灯は、24時間営業のコンビニエンスストアー店舗の天井に設置する照明、オフィスビルの照明、地下鉄や鉄道駅舎やプラットホーム、駐車場等の天井照明等、アフターサービスがしにくい場所に設置すれば、従来蛍光灯より投資効果が得られる。例えば、当方の試算では、寿命が5倍以上長く、消費電力が50%以上削減でき、5,000円/トンの二酸化炭素の排出削減ができ、LED蛍光灯の初期投資が効果であっても、三年で償却できる。The 0004 milky white light diffusing pipe-shaped lamp shade can realize an LED fluorescent lamp in which the shape of the lamp is not visible from the lower side of the LED fluorescent lamp and the hot spot is not visible. This type of LED fluorescent lamp is installed in a place where after-sales service is difficult, such as lighting installed on the ceiling of a 24-hour convenience store store, lighting of office buildings, ceiling lighting of subways, railway stations, platforms, parking lots, etc. In this way, it is possible to obtain an investment effect compared to conventional fluorescent lamps. For example, in our trial calculation, the lifetime is more than 5 times longer, the power consumption can be reduced by 50% or more, the carbon dioxide emission of 5,000 yen / ton can be reduced, and the initial investment of the LED fluorescent lamp is effective. Can be depreciated in 3 years.
また、前記0005のランプシェードは図3 1−2が乳白色になっているため、光源の24%以上が反射して、下方に光を透過させるため、全体が透明や白色半透明単独よりも、図3 1−3の光透過性がより大きくなり、より明るい照明が得られる。これにより、ランプシェードを通して、ランプが見えても良いかどうかのLED蛍光灯用途別ニーズに沿って、ランプシェードの光線透過率を74〜98%の範囲内で調整できる。このタイプのLED蛍光灯は、スーパーマーケットやコンビニエンスストアーの冷蔵ショーケースや自動販売機に使用される。In addition, since the lamp shade of 0005 is milky white in FIG. 3 1-2, more than 24% of the light source reflects and transmits light downward, so the whole is more transparent or white translucent than alone. The light transmittance of FIGS. 31 and 3 is increased, and brighter illumination is obtained. Thereby, the light transmittance of the lamp shade can be adjusted within the range of 74 to 98% in accordance with the needs according to the use of the LED fluorescent lamp whether the lamp may be visible through the lamp shade. This type of LED fluorescent lamp is used in refrigerated showcases and vending machines at supermarkets and convenience stores.
前記0004の乳白色光拡散パイプ状ランプシェードは、我々の実験結果では、ポリカーボネート樹脂の光拡散性の改良により、約74%の光線透過率を達成し、LEDランプ数の削減にも役立たせることができた。同時に、LED蛍光灯のどの方向から見てもランプの陰り(ホットスポット)が見えない製品を完成させた。According to our experimental results, the 0004 milky white light diffusing pipe-shaped lamp shade achieves a light transmittance of about 74% by improving the light diffusibility of the polycarbonate resin, and can help reduce the number of LED lamps. did it. At the same time, a product was produced in which the shade of the lamp (hot spot) was not visible when viewed from any direction of the LED fluorescent lamp.
また、前記0005のランプシェード図3 1−2は、光拡散性を有する乳白色のポリカーボネート樹脂にして、図3 1−3は乳白色と透明ポリカーボネート樹脂を混合した白色半透明の光拡散性を有した樹脂で作成した。その結果、図3 1−3ランプシェードにも眩しさ防止の機能を付与し、点灯時、ホットスポットが目立たない程度に、少し見えるものの、光を下方向に光源の85%の光透過させることができた。In addition, the lampshade 0005 of FIG. 31-2 is a milky white polycarbonate resin having light diffusibility, and FIG. 3 1-3 has a white translucent light diffusibility obtained by mixing milky white and a transparent polycarbonate resin. Made of resin. As a result, the function of preventing glare is also imparted to the lamp shade in FIG. 31 to allow light to pass through 85% of the light source in the downward direction, although the hot spot is not visible when it is lit. I was able to.
さらに、前記0009のランプシェードで、図3 1−3のみに眩しさ防止のための光拡散剤を少し付与したため、少し白濁しているが、透明に近い半透明ポリカーボネート樹脂を使用して作成したランプシェードは、下方向からランプの存在が見えるが、光が眩しくない状態になっており、光を下方向に光源の92%の光を透過させることができた。Furthermore, in the lamp shade of 0009, a light diffusing agent for preventing glare was applied only to FIGS. 31 and 3, so it was slightly cloudy, but was made using a translucent polycarbonate resin that was nearly transparent. In the lamp shade, the presence of the lamp can be seen from below, but the light is not dazzled, and 92% of the light from the light source can be transmitted downward.
