Description

一种带反光层的LED灯丝型球泡灯
技术领域
本发明涉及一种LED灯泡,尤其涉及一种带反光层的LED灯丝型球泡灯。
背景技术
由于LED灯的使用寿命长、能耗低、节约能源显著,因此LED 灯作为光源已广泛地应用于日常生活中,如LED灯泡。全角度发光的LED灯泡备受欢迎,但是由于目前单LED发光角度很难实现全角度均匀发光。因此,如何提高全角度LED灯泡的光照不均匀、光圈、光斑、正中心点光强偏弱问题成为LED 灯泡技术中重大问题。
发明内容
本发明的目的是针对现有技术的不足,提供一种带反光层的LED灯丝型球泡灯。
本发明的目的是通过以下技术方案实现的:一种带反光层的LED灯丝型球泡灯,包括玻璃泡壳发明、上支架发明、LED灯条发明、芯柱发明、LED 电源发明、灯头发明,还包括玻璃泡壳发明底部的反光层发明,所述反光层发明位于玻璃泡壳发明的内壁或外壁,厚度为1 ~200μm;反光层发明通过真空蒸镀、电子束蒸发、磁控溅射或CVD沉积涂覆在玻璃泡壳发明的底部。
进一步地,反光层发明包括反光内层和反光外层,反光层发明位于玻璃泡壳发明的内壁,反光内层位于玻璃泡壳发明内壁和反光外层之间,反光内层的折射率高于反光外层的折射率。
进一步地,反光层发明包括反光内层和反光外层,反光层发明位于玻璃泡壳发明的外壁,反光外层位于玻璃泡壳发明外壁和反光内层之间,反光内层的折射率高于反光外层的折射率。
本发明的有益效果是:反光层起到反射作用,从而解决了现有的全角度发光灯泡的光照不均匀、光圈、光斑、正中心点光强偏弱问题,提高了光照均匀度,光损失小,节能环保。

具体实施方式
下面结合说明书附图对本发明作进一步说明。
如图1和2所示,一种带反光层的LED灯丝型球泡灯,包括玻璃泡壳1、上支架2、LED灯条3、芯柱4、LED 电源5、灯头6、导丝9,还包括涂覆于玻璃泡壳1底部的反光层8,由于玻璃泡壳1是透明材质,反光层8可以在玻璃泡壳1内壁或外壁。反光层8可以由反光内层和反光外层组成,反光内层的折射率高于反光外层的折射率。当反光层8位于玻璃泡壳1的内壁,反光内层位于玻璃泡壳1内壁和反光外层之间,当反光层8位于玻璃泡壳1的外壁,反光外层位于玻璃泡壳1内壁和反光内层之间。折射率的高低匹配可以形成全反射效果,增加3-5%的反射率和补光效果。
反光层8厚度为1~200μm,可以为Au、Ag、Al、Cu、Si、Fe、Ni、Cr等金属,或NiCr、SiAl、TiAl、ZnAl、AuGe、CuInGa等金属合金,或ITO、TiOx、AlOx、CrOx、Y2O3、ZnO、Ta2O5等氧化物,或MgF2、BaF2、NbF3、LaF3等氟化物,或TiN、SiC、CdS、BaTiO3、ZnS等其他化合物,或PTFE、聚对二甲苯化合物等有机物,但不限于此;也可以为均匀分布有折射率高于1.9的玻璃微珠的硅胶涂层,反光层8能将灯泡轴线外围的部分光束反射到灯具需要照射的前方,用以提高灯泡的光强利用率,增强灯泡照射方向的光线照射强度,从而补充正中心点的光强。反光层8可以通过真空蒸镀、电子束蒸发、磁控溅射、CVD沉积等方法涂覆在玻璃泡壳1上。
图3为无反光层的LED灯丝型球泡灯的发光效果图,由图中可以看出,光照不均匀、正中心点光强偏弱,而在本发明中,由于部分光束经过玻璃泡壳1的反光层8反射回来,增强了中心点位置的光强,使其发光更加均匀(如图4所示)。
