Description

一种全方位出光LED灯 技术领域
本发明涉及一种LED灯，尤其涉及一种能全方位出光的LED灯。
背景技术
近年来，随着LED技术的不断发展，照明用LED灯具的各种性能有了很大的提高。LED灯具具有寿命长、发光效率高、没有紫外辐射、节能效果好等一系列的优点，成为未来光源的发展趋势。
但是LED光源具有方向性，不像白炽灯等一样可以做到360度发光，因此，当采用LED作为光源来取代传统的白炽灯或其他光源时，其发光效果受到一定的限制。特别是将LED制成传统的灯管形状的日光灯时，如中国专利CN102022651A所公开的“LED日光灯”包括灯罩、LED光源组件、LED驱动组件、两端盖以及散热外壳，灯罩与散热外壳连接，两端盖分别扣合于所述灯罩和所述散热外壳连接后的两端，灯罩和散热外壳的横截面均呈弧形，且灯罩和所述散热外壳形成一腔体，所述LED光源组件和所述LED驱动组件位于所述腔体内。该种LED日光灯，为了而满足LED的散热需求，所以只能将LED设置成一平面，因此，虽然其外形具有日光灯的长直筒形状，但是其发光面积仅仅只有180度，即从一平面开始发光，并不能做到360度全方位发光。因此，现今的LED灯中，散热面积与发光面积是相互矛盾的，因此，现有的LED日光灯，都不能做到在满足散热需求的情况下的360度全方位发光。
发明内容
本发明所要解决的技术问题是提供一种既具有较好的散热性能，又能满足全方位发光的LED灯。
本发明解决上述技术问题所采用的技术方案为：一种全方位出光LED灯，包括电连接器、与电连接器相连的连接件和与连接件相连的透光罩，所述电连接器内设置驱动器，其特征在于：所述透光罩包括至少两个，这多个透光罩相互连接围成一整体的灯罩形状，并且该透光罩之间围成一通道，所述通道的两端开口与外界连通，通道的至少一端的透光罩上固定有一连接件，所述连接件内形成一空腔，所述连接件的空腔连通至透光罩之间的通道，并且所述连接件上设有通风孔连通至外界，所述透光罩上固定有LED发光元件，所述LED发光元件的发光面朝向透光罩的形成的腔体，所述LED发光元件通过导线连接至电连接器内的驱动器。
优选地，为了便于固定，所述透光罩围成所述通道的部分上设有缺口，所述缺口内固定有发光板，所述发光板上固定所述LED发光元件。
作为本发明的一个实施例，所述通道一端的透光罩固定连接连接件，所述电连接器的上端固定所述连接件，所述连接件的上方连接所述透光罩，所述透光罩围成一灯泡形状，所述连接件的顶部具有通孔连通至所述通道，所述连接件的侧面上设有通风孔。
优选地，所述连接件包括与电连接器连接的连接部分，以及固定位于连接部分上并且隔开电连接器与连接件内的空腔的底盖，与所述底盖上下连接形成所述空腔的顶盖，所述通风孔位于所述底盖的侧周面上，沿侧周面均匀间隔分布，所述顶盖上设有所述通孔。
为了便于固定，所述顶盖上沿所述通孔的周边设有向上延伸的挡板，所述顶盖上还固定有位于挡板外侧与所述挡板间隔设置的定位板，所述挡板和定位板之间卡合固定所述透光罩的底部。

实施例二：
如图4、5所示，为本发明的第二实施例，该图中省略了电连接器，该实施例中与电连接器连接的连接件2’为一中空筒形结构，该中空筒形结构内设有两个与其轴向垂直的隔板隔出所述空腔21’，其中一块隔板上设有通孔22’，所述空腔21’所对应的周面上设有通风孔26’，该通风孔26’沿空腔21’所对应的连接件的周面均匀间隔设置，具有通孔22，的隔板上设有沿通孔22’的周边向上突起的挡板27’，该挡板27’用于固定连接至少两个透光罩3’，所述透光罩3’为长条形状，其一边为一平面，另一边为截面为弧形的曲面，并且该至少两个透光罩3’的曲面相互拼接形成一长圆筒灯罩，该透光罩3’的平面相互拼接围成中空上下延伸的通道4’，该通道4’两端开口，底端即与该通孔22’固定，该透光罩3’对着该通道4’的面，即平面上固定有发光板5’，优选地，该面上具有缺口用于安装发光板5’，该发光板5’朝向透光罩3’外侧，即朝向透光罩3’腔体的一面上固定有多个LED发光元件，该LED发光元件通过连接线连接至设于连接件2’上的插针，通过该插针与外界的电连接器连接。并且本领域技术人员也可以了解到，该LED发光元件也可以直接固定于透光罩3’围成通道4’的面上，可以省略该发光板5’。LED发光元件也可以固定于透光罩3’外侧的面上并且发光面朝向腔体设置。
并且该实施例中，透光罩3’的一端与第一连接件2’连接，另一端可以相互连接露出通道4’，也可以是连接至一第二连接件2”，如图4、5所示，该第二连接件2”与第一连接件2’相同，也具有一空腔，该空腔的一端与通孔22’连通，空腔的周面具有通风孔26”连通至外界，该第二连接件2”内同样具有导线连接LED发光元件和其上的插针，这样，整个LED灯形成一灯管形状，两头具有插针，可以当做一般的日光灯使用。
上述的LED灯有至少两个拼接形成一整体的透光罩，并且透光罩之间围成一通道，该通道的一端通过连接件连通至外界，另一端直接连通至外界，或者两端均通过连接件连通至外界，形成一对流通道用于散热，这样的LED灯，既能实现360度全方位的照明，发光角度大、发光效率高，而且散热性能好，提高了LED灯的使用寿命，而且该LED灯的透光罩，可以根据需要设计组合成各种不同长度、不同形状的灯罩，不但加工方便，更加拓展了该LED灯的适用范围。
