    • A key sheet module is provided to dispose an LED or an electric device in an optimum location by using a thin conductive film jumper, thereby significantly improving lighting efficiency of the keypad lighting in one-sided circuit board. Between predetermined spaced line patterns(4) of plural line patterns, an insulating layer is formed. On the insulating layer, a conductive film jumper(18) is formed to stereoscopically connect the spaced line patterns as crossing each other. A white spacer(8) is a reflection plate and has an LED(Light Emitting Diode)(5) electrically connected with the line pattern and a mount hole(8a) for exposing a contact switch(3). Electric devices(6) electrically connected to the line patterns are arrange in left and right sides of a print line substrate so as not to block irradiation light from the LED for irradiating light to the contact switch. The white spacer is arranged within the electric devices arranged in both sides.
    • 提供了一种按键板模块,通过使用薄导电膜跳线将LED或电子设备配置在最佳位置,从而显着提高了单面电路板中键盘照明的照明效率。 在多个线图案的预定间隔线图案(4)之间,形成绝缘层。 在绝缘层上,形成导电膜跳线(18),以便彼此交叉地立即连接间隔开的线图形。 白色间隔物(8)是反射板,并且具有与线图形电连接的LED(发光二极管)(5)和用于使接触开关(3)露出的安装孔(8a)。 电连接到线图案的电子装置(6)布置在打印线基板的左侧和右侧,以便不阻挡来自用于向接触开关照射光的LED的照射光。 白色间隔物布置在布置在两侧的电气装置内。

    • A keypad assembly is provided to illuminate regularly an overall area of a keypad by using relatively a few light emitting elements by using an optical waveguide which can guide light to a keypad and selectively output light to only a part of the keypad which needs illumination. A keypad assembly comprises plural key buttons(20), plural light emitting elements(30), a light waveguide(40), plural reflection patters(50) and an assistant layer(60). The plural light emitting elements(30) are arranged on a base plate. The light waveguide(40), having reflective index and being arranged at a lower part of the key buttons(20), guides the light of the light emitting elements internally by a total reflection condition. The plural reflection patters(50), formed in the light waveguide(40), reflect the light, guided into the light waveguide(40), toward the key buttons(20). The assistant layer(60), having reflective index lower than the light waveguide(40) and coated on a surface of the light waveguide(40), makes the total reflection condition regular on an overall area of the keypad.
    • 提供键盘组件以通过使用能够将光引导到小键盘并且将光仅选择性地输出到需要照明的键盘的一部分的光波导通过使用相对少数的发光元件而规则地照亮小键盘的整个区域。 键盘组件包括多个键按钮(20),多个发光元件(30),光波导(40),多个反射图案(50)和辅助层(60)。 多个发光元件(30)配置在基板上。 具有反射指数并布置在键按钮(20)的下部的光波导(40)在内部引导发光元件的全反射条件。 形成在光波导(40)中的多个反射图案(50)将被引导到光波导(40)中的光朝向键按钮(20)反射。 具有低于光波导(40)的反射率并涂覆在光波导(40)的表面上的辅助层(60)使得全反射条件在键区的整个区域上是常规的。
