Abstract

<P>PROBLEM TO BE SOLVED: To provide a light guide plate device which can give enough visibility even in the daytime for an indicating lamp or the like which uses an LED as a light source in which case visibility is inferior in luminance. <P>SOLUTION: An LED light source in a base plate case emits a beam, while being interfacially reversed, direct on a slit face of a diffusing face on which V-shaped slits are cut on a transparent acrylic light guide plate and which undergoes a frosting treatment, and displays the diffused face at a high luminance. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は導光板装置に関する。  The present invention relates to a light guide plate device.

光源の光線を導入口より導入されて反射面にて反射され放射面より外部に放射される導光板を備えた導光板装置は公知の技術である。  A light guide plate device including a light guide plate that is introduced with a light beam of a light source through an introduction port, reflected by a reflection surface, and emitted from the emission surface to the outside is a known technique.

発明が解決しょうとする課題Problems to be solved by the invention

しかし導入された照射光線を反射面において反射した光線を表面に照射する装置が一般であるが、正面の輝度が不十分で昼間に視認できない場合もあるが、本装置は導光板において直接拡散し、視認性の高い表示灯及び装飾装置として応用することにある。  However, it is common to use a device that irradiates the surface with reflected light that has been reflected by the reflecting surface.However, the brightness of the front surface may be insufficient and may not be visible in the daytime. It is to be applied as a highly visible indicator lamp and a decoration device.

課題を解決するための手段Means for solving the problem

本発明は、光源より照射され光を導光板にＶ字形状のスリットを備えそのスリット面にフロスト加工を施し直接視認できる装置とした。  The present invention is an apparatus in which light irradiated from a light source is provided with a V-shaped slit in a light guide plate, and the slit surface is subjected to frost processing to be directly visible.

実施の形態Embodiment

本発明の実施例を添付図に従って述べる。
まず図１の５の透明アクリル板製の導光板の６．のスリットを３０度角に加工を７．のスリットは３５度角に８．のスリットは４０度角に加工することにより均等な視認性を得る事ができ、また昼間の視認性を増す為図１の４、の光源ケースの内部に１．２．３のＬＥＤを設置することで、図１の１０．１１．１２．１３の強い照射光線を得ることが出来る。Embodiments of the present invention will be described with reference to the accompanying drawings.
First, the light guide plate made of a transparent acrylic plate 5 in FIG. 6. Process the slit of 30 degrees to 7. The slit of 8 is 35 degrees angle 8. In order to increase the visibility in the daytime, an LED of 1.2.3 is installed inside the light source case of 4 in FIG. As a result, a strong irradiation light beam of 10.11.12.13 in FIG. 1 can be obtained.

またこの照射光線を図１の６．７．８．９．のスリット面にフロスト加工を施した拡散面にて視認性を高める、また図１．のＬＥＤ１．を青、２．を赤、３．を緑色に設置することにより、図１．の５の導光板のスリット部分６．７．８．９．に調光された色彩を表示することが出来、装飾装置としても応用出来る。  Further, this irradiation light beam is 6.7.8.9. Visibility is enhanced by a diffusing surface with a frosted slit surface. LED1. Blue, Red. By placing the green in FIG. The slit portion of the light guide plate of No. 5 6.7.8.9. It is possible to display dimmed colors, and it can also be used as a decoration device.

本発明の実施例に係る導光板の断面図である。  It is sectional drawing of the light-guide plate which concerns on the Example of this invention. 本発明の実施例に係る導光板の平面図である。  It is a top view of the light-guide plate which concerns on the Example of this invention.
