传统的键盘开关在操作过程中使用者无法直观地判断该按键开关开启/关闭状态，故使用者操作时会倍增困扰。目前，市面上出现了一些带灯的键盘开关，其针对每个键盘开关设置一LED灯，以实现键盘开关发光功能；在实际生产制作时往往会发现，其存在结构复杂、生产成本较高等不足，在使用过程中，需要针对单个键盘开关的LED灯进行维护，比较麻烦，尤其是外露式的LED灯，其维修更换频率更大，另外，现有技术中的发光键盘开关，其发光效果也欠佳。
因此，需要研究出一种新的技术方案来解决前述问题。
实用新型内容
有鉴于此，本实用新型针对现有技术存在之缺失，其主要目的是提供一种发光键盘开关，其易于制作，成本低廉，简化了组装工序，组装更为简便，且增大了透光面积，很大程度上提高了发光效果。

作为一种优选方案，所述上盖表面设置有用于增强出光效果的导光凸点。
作为一种优选方案，所述上盖具有顶端面及周侧面，其顶端面及周侧面均设置有前述导光凸点，或者仅其顶端面设置有前述导光凸点，或者仅其周侧面设置有前述导光凸点。

作为一种优选方案，所述上盖对应导光柱顶部上方位置形成有避空凹腔，该避空凹腔至少具有侧向开口，该避空凹腔的底部设置有前述导光凸点。
作为一种优选方案，所述导光柱一体向下延伸设置，且导光柱对应位于上盖中心侧旁。
作为一种优选方案，所述导光柱底部为平面或呈向上拱起的凹曲面。
作为一种优选方案，所述上盖的侧面开设有卡槽，相应地，前述底座的外侧面凸设有卡榫，当上盖安装于底座上，其卡榫扣于相应卡槽内。
作为一种优选方案，所述底座下方设置有导光板，前述导光柱直接接触于导光板 的上表面，或者，于导光板上凹设有嵌孔，将导光柱下端嵌于导光板的嵌孔内；前述光源针对导光板设置，光源的灯光依次经导光板、导光柱传导再由上盖表面射出。
作为一种优选方案，所述底座下方设置有电路板，前述光源设置于电路板上，前述导光柱的入光端直接正对光源的出光面。

具体实施方式
请参照图1至图13所示，其显示出了本实用新型之多种实施例的具体结构；该发光键盘开关包括有底座11、静触片12、动触片13、上盖14以及用于控制动触片13与静 触片12接触或分离的按键15；该静触片12和动触片13均设置于底座11上，该静触片12的焊接脚和动触片13的焊接脚均伸出底座11外，该上盖14安装于底座11上，于本实施例中，所述上盖14的侧面开设有卡槽29，相应地，前述底座11的外侧面凸设有卡榫30，当上盖14安装于底座11上，其卡榫30扣于相应卡槽29内，其组装方便快捷且稳固；该底座11下段部分隐于面板18下方；该按键15设置于底座11上并露出上盖14，针对该按键15设置有复位弹簧16，并按键上方连接有键帽19。
于本实用新型中，前述上盖14为透光体，即其采用透光材料制造而成，在结构设计上，该上盖14底部一体延伸形成有导光柱20，这样，导光柱20和上盖14可以一次注塑成型而成，降低了生产制作成本，简化了组装工序，组装也更为方便；本实用新型中设计有光源，并将光源的灯光经导光柱20传导再由上盖14表面射出，整个上盖14都可以透光，其透光面积大，发光效果好。
具体而言，如图8至图12所示，该导光柱20一体向下延伸设置，其底部为平面24或呈向上拱起的凹曲面25，并导光柱20对应位于上盖14中心侧旁，该上盖14具有顶端面及周侧面，此处其周侧面由若干斜面沿周向依次拼接而成，整个上盖14的外表面都可以成为出光面。
如图8所示，上盖14的外表面设计为光面；如图9所示，上盖14的顶端面设置有若干用于增强出光效果的导光凸点22，而其周侧面则设计为光面；如图10所示，上盖14的周侧面设置有导光凸点22，而其顶端面则设计为光面；如图11所示，上盖14的顶端面及周侧面均设置有导光凸点22；如图12所示，该上盖14对应导光柱20顶部上方位置形成有避空凹腔23，该避空凹腔23具有侧向开口和顶端开口，该避空凹腔23的底部设置有若干导光凸点22，其底部则作为主要的出光面。
接下来，介绍前述一体化的导光柱20、上盖14结构应用于键盘开关中的几种实施例：
如图1至图3所示，该底座11下方设置有导光板17，对应导光板17设置有光源，所述光源设置于导光板17的侧向位置，当然，光源横向或纵向设置等均可，也可如图7所示贴片LED28那样，将插脚式LED设置为直接正对导光柱20的入光端，即竖向设置于导光柱下方；所述光源可以选用单色LED灯27或多彩LED灯26(如图1a所示)等，其数量可按需设置，一颗或一颗以上均可，该光源位于面板18下方，避免光源外露，光源不易受到损坏，其使用寿命更长，降低维修更换频率；当然该面板18可按需选择应用与否，其并非本实用新型之产品的必须组件。前述导光柱20直接接触于导光板17的上表面，光源的灯光依次经导光板17、导光柱20传导再由上盖14表面射出。
通过导光板17等结构设置，实现多个键盘开关共用光源，大大减少了光源使用数量，节约了生产制作成本；此处，所述底座11下方设置有电路板21，前述导光板17位于电路板21下方(亦可将导光板17设置于电路板21的上方，在此不作限制)。
如图4所示，其主要结构与前述图1至图3所示产品相同，其主要不同点在于：该导光板17上凹设有嵌孔29，组装导光柱20时，将导光柱20下端嵌于导光板17的嵌孔29内；对比图3和图4，不难看出，图4所示实施例中导光柱20长度更长些，当然，嵌入式导光柱结构设计，有利于增大导光柱的入光面，提高了光效。
如图5至图7所示，本实施例中，其光源为贴片LED28，这样，光源直接贴装于电路板21上，可以省去前述两实施例中的导光板，将述导光柱20的入光端直接正对光源的出光面即可，也缩短了导光柱20的长度，这样需要针对每个键盘开关设置单独的贴片LED28，当然，本实施例也可以应用导光板，例如将导光板设置于电路板上方，导光柱则接触导光板上方进行导光，如此也可实现多个键盘开关共用光源，当然，本实用新型中对此并不 作限制，本实用新型的主要创新点在于上盖与导光柱的一体化设计；另外，需要说明的是，请参照图7所示，此处的导光柱20的底面设计为向上拱起的凹曲面25，其形成更大角度范围、更大面积的入光面，当然，也可设计为平面24。
本实用新型的设计重点在于，其主要是通过将上盖和导光柱一体化设计，两者可一次注塑成型，易于制作，成本低廉，简化了组装工序，组装更为简便；同时，整个上盖都可以透光，增大了透光面积，很大程度上提高了发光效果。
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型的技术范围作任何限制，故凡是依据本实用新型的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
