Specifically, members having functions such as refraction, reflection, total reflection, specular reflection, lens refraction, half mirror are fabricated in a combined configuration to allow to irradiate the sides and the top and bottom of each side with light. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【従来の手段】現在のパッケージ型発光体(例、発光ダイオード通称LED)は、発光部より発生した光は、光の進行方向と平行に進み、照射、拡散して発光する。
【0002】パッケージ型発光体(例、LED)外部に突起物を付けて、光を拡散するものがある。
【0003】光の進行方向に凸または、レンズ加工して光を拡散するものがある。
【0004】
【発明の要点】この発明はパッケージ型発光体(例、LED)の側面、及び側面上下に光を照射すること。
【0005】
【従来の問題点】従来のパッケージ型発光体(例、LED)は光を側面、及び側面上下に照射できない。もし、可能な物が有っても、光はやわらかく、鋭い光とはならない。
【0006】
【発明の実施の形態】本発明は透明パッケージ入りの発光体から発する光を、基本図1図のようにパッケージP(円柱または角柱)・発光部U・反射面Mとして、発光部Uより発した光は反射面Mに反射し、パッケージPの側面より発光する。
【0007】
反射面Mは粒子面・滑面・ハーフミラーコーティング面・鏡面、等に変化させることによって反射率を調整できる。同時に透過率も変わる。
【0008】
また、反射面Mの光に対して角度を変化させることにより側面方向の光の照射角度を変えることができ、透過率も可変できる。
【0009】
反射面Mは、直線で表示しているが、凸弧・凹弧・方物弧・楕円弧、等に変化させることにより散光、集光が可能となる。
【0010】
基本図2図は、基本図1図の側面にレンズ体L1のようなの加工を施す。
レンズ体L1の光軸は反射面Mをかいし発光体半分の部分の中心線と結びつくものとする。レンズ体Lの焦点距離内に発光体Uを設置すれば、レンズ体L1を通した発光体Uは、虚像となり拡大される。また、焦点の位置にあればその光は結像することなく揺らいで見える。
【0011】
基本図3図では、基本図2図における反射面Mの透過性(粒子面、滑面、ハーフミラー等)を利用して、パッケージPの円錐空間に同型の円錐付凸レンズL2を取り付ける。設計位置はL1と同様とする。
取り付け方は、透明スペーサーを挟み空間を空けて取り付ける方法と、密着して取り付ける方法とがあり各々光の効果が変化する。
また、空間に小さな高反射材(例、アルミ箔の小片)を適量入れれば輝く効果の表現もできる。
【0012】
【発明の効果】パッケージ型発光体(例、LED)の側面の発光性は著しく低く、または発光できても、光の鋭さは低下する。しかし、本発明では発光体の側面、側面上下からの発光が可能となる。形態は、基本図1、基本図2、基本図3、を基本とし、応用図1、応用図2、応用図3、などに発展することができる。

2. Description of the Related Art At present, light emitted from a light emitting portion of a package type light emitting body (for example, an LED called a light emitting diode) travels in parallel with a traveling direction of light, and is emitted and diffused to emit light.
[0002] There is a package type light emitting body (for example, LED) in which a projection is attached to the outside to diffuse light.
[0003] There is a type that is convex in the traveling direction of light or diffuses light by lens processing.
[0004]
SUMMARY OF THE INVENTION The present invention is to irradiate light on the side surface of a package type light-emitting body (eg, LED) and on the upper and lower sides of the side surface.
[0005]
2. Description of the Related Art Conventional package-type light-emitting bodies (eg, LEDs) cannot irradiate light to the side surface and the upper and lower sides. If there is something possible, the light is soft and not sharp.
[0006]
DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, light emitted from a light-emitting body containing a transparent package is emitted from a light-emitting portion U as a package P (cylinder or prism), a light-emitting portion U, and a reflection surface M as shown in FIG. The reflected light is reflected by the reflection surface M and emitted from the side surface of the package P.
[0007]
The reflectance can be adjusted by changing the reflection surface M to a particle surface, a smooth surface, a half mirror coating surface, a mirror surface, or the like. At the same time, the transmittance changes.
[0008]
Further, by changing the angle with respect to the light on the reflection surface M, the irradiation angle of the light in the side direction can be changed, and the transmittance can also be changed.
[0009]
Although the reflecting surface M is displayed as a straight line, light can be scattered and condensed by changing it into a convex arc, concave arc, rectangular arc, elliptical arc, or the like.
[0010]
In FIG. 2, the side surface of FIG. 1 is processed like a lens body L <b> 1.
It is assumed that the optical axis of the lens body L1 is connected to the center line of the half of the light emitting body through the reflecting surface M. If the light emitter U is set within the focal length of the lens body L, the light emitter U passing through the lens body L1 becomes a virtual image and is enlarged. If the light is at the focal point, the light appears to fluctuate without forming an image.
[0011]
In FIG. 3, a convex lens L2 with the same shape is attached to the conical space of the package P using the transmissivity (particle surface, smooth surface, half mirror, etc.) of the reflection surface M in FIG. The design position is the same as L1.
There are two methods of attachment: a method of attaching the transparent spacer with a space between them, and a method of attaching the transparent spacer in close contact.
If a small amount of high-reflection material (for example, small pieces of aluminum foil) is put in the space in an appropriate amount, the effect of shining can be expressed.
[0012]
According to the present invention, the light emitting property of the side surface of a package type light emitting body (eg, LED) is extremely low, or even if light can be emitted, the sharpness of light is reduced. However, in the present invention, light can be emitted from the side surface of the light-emitting body, and from the top and bottom of the side surface. The form is based on the basic diagram 1, the basic diagram 2, the basic diagram 3, and can be developed into the application diagram 1, the application diagram 2, the application diagram 3, and the like.
