Abstract

本发明涉及一种LED筒灯，包括圆形的灯筒，灯筒后端内设有灯座，灯筒前端罩设有透光板，灯座的前端面上设有圆盘形的印制板，印制板前面均匀分布有点光源，印制板前面还固定有分光座，分光座上设有与各个点光源一一对应分布的聚光凹部，聚光凹部为自前向后逐渐缩小的锥形，聚光凹部的最后端设有至少供点光源的发光端深入的通孔，聚光凹部的前端开口并朝向透光板，聚光凹部的内壁面为反光面。在印制板上通过分光座对点光源的照射方向和范围进行设定，从而免去了在印制板上重新设计点光源的工序，也就避免了重新排布点光源所引起的电路排序的问题，同时也使得罩设而出的光线更为均匀。

Description

一种LED筒灯
技术领域
本发明涉及一种LED筒灯。
背景技术
LED筒灯中LED是英文light emitting diode(发光二极管)的简写，它的基本结构是一块电致发光的半导体材料芯片固化到支架上，然后连接芯片和电路板，并用环氧树脂密封四周，起到保护芯片的作用，最后安装外壳。LED筒灯有使用低压电源、耗能少、适用性强、稳定性高、响应时间短、对环境无污染、多色发光等优点而得到广泛应用。但同时，由于LED光源发光特性的影响，其照射度偏低、光照均匀度不够等，在具体应用成LED筒灯时，必须对光源分布结构进行二次设计，但现有市场上，对光源分布位置二次设计后的LED筒灯多数结构复杂，并且仍然存在光源照射度偏低及光照均匀度不足的问题。
发明内容
本发明旨在提供一种光照均匀的LED筒灯。
为解决上述技术问题，本发明中LED筒灯的技术方案如下：
LED筒灯，包括圆形的灯筒，灯筒后端内设有灯座，灯筒前端罩设有透光板，灯座的前端面上设有圆盘形的印制板，印制板前面均匀分布有点光源，印制板前面还固定有分光座，分光座上设有与各个点光源一一对应分布的聚光凹部，聚光凹部为自前向后逐渐缩小的锥形，聚光凹部的最后端设有至少供点光源的发光端深入的通孔，聚光凹部的前端开口并朝向透光板，聚光凹部的内壁面为反光面。
分光座为多个聚光罩一体组合而成，聚光罩与点光源一一对应设置，聚光凹部为聚光罩的凹部，并且各个聚光罩的过渡位置为圆弧形的相贯线，相贯线自中点向两端逐渐向前翘起。
各个点光源在印制板上沿同心圆周方向呈圈状分布，各个聚光罩中最边缘的一圈的外边沿为与灯筒的内壁吻合的斜切面，并且灯筒的内壁上设有反光涂层。
灯座上设有位于印制板后方的散热板，灯筒的后端罩设有罩在散热板后方的散热罩，散热罩为铝制材料。
本发明的有益效果是：
在印制板上通过分光座对点光源的照射方向和范围进行设定，从而免去了在印制板上重新设计点光源的工序，也就避免了重新排布点光源所引起的电路排序的问题，同时也使得罩设而出的光线更为均匀。
附图说明
图1是本发明中LED筒灯的结构示意图；
图2是图1中灯座和分光座的结构示意图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
本发明中LED筒灯的实施例：如图1和图2所示，该LED筒灯包括圆形的灯筒1，灯筒1后端内设有灯座2，灯筒1前端罩设有透光板3，灯座2的前端面上设有圆盘形的印制板4，印制板4前面均匀分布有点光源5，印制板4前面还固定有分光座6，分光座6上设有与各个点光源5一一对应分布的聚光凹部，聚光凹部为自前向后逐渐缩小的锥形，聚光凹部的最后端设有至少供点光源5的发光端深入的通孔，聚光凹部的前端开口并朝向透光板3，聚光凹部的内壁面为反光面。
分光座6为多个聚光罩一体组合而成，聚光罩与点光源5一一对应设置，聚光凹部为聚光罩的凹部，并且各个聚光罩的过渡位置为圆弧形的相贯线，相贯线自中点向两端逐渐向前翘起。各个点光源5在印制板4上沿同心圆周方向呈圈状分布，各个聚光罩中最边缘的一圈的外边沿为与灯筒1的内壁吻合的斜切面，并且灯筒1的内壁上设有反光涂层。
灯座2上设有位于印制板4后方的散热板7，灯筒1的后端罩设有罩在散热板7后方的散热罩，散热罩为铝制材料。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
