Description

LED吊顶灯
技术领域
本发明涉及一种LED吊顶灯，特别涉及一种集照明和装饰效果于一体的LED吊顶灯。
背景技术
LED借助体积小、寿命长、低驱动电压、启动快速、环保、抗震抗压等优点，现已被广泛地应用于日常室内照明，特别是吊顶灯中。LED吊顶灯满足了人们对亮度、节能灯方面的要求，却不能满足人们对美感的要求，不能达到像水晶灯一样在天花板上形成具有美感的辐射状光形，缺乏装饰效果。
发明内容
有鉴于此，本发明提供一种集照明与和装饰效果于一体的LED吊顶灯。
一种LED吊顶灯，包括用于照明的主照明装置，主照明装置包括灯座及与灯座固定连接的固定架，所述灯座背向固定架一侧固定安装有LED发光颗粒的第一电路板，还包括固定于灯座上面向固定架一侧的辅助照明装置，所述辅助照明装置包括安装有LED发光颗粒的第二电路板、透镜及反射镜，所述透镜位于第二电路板的上方，所述第二电路板和透镜均位于反射镜内，所述透镜用于将来自第二电路板的LED发光颗粒发射的光分割成多个光束，所述两相邻光束之间形成一无光区，所述反射镜用于反射该多个光束使该多个光束投射至天花板上。
上述LED吊顶灯通过透镜将来自第二电路板的LED发光颗粒所发射的光分割成多个光束，使相邻光束之间形成无光区，从而使天花板上形成辐射状光形，达到装饰效果。

图2是图1中II处的放大图。
图3是图1中的透镜的立体图。
图4是图1中的透镜另一视角的立体图。
图5是图1中的LED吊顶灯发射的光自透镜射出后的光路示意图。

具体实施方式
请同时参考图1及图2，LED吊顶灯10包括用于照明的主照明装置20及多个用于装饰的辅助照明装置30，辅助照明装置30固定于主照明装置20上。
主照明装置20包括灯座22、与灯座22固定连接的灯罩24及固定地连接于灯座22与天花板50之间的固定架26。灯座22背向固定架26一侧固定一安装有LED发光颗粒的第一电路板(图未示)。LED发光颗粒发射的光透过灯罩24用于照明。
辅助照明装置30固定于灯座22上面向固定架26一侧。本实施方式中，辅助照明装置30为两个，对称地固定于固定架26两侧。每个辅助照明装置30包括安装有LED发光颗粒32的第二电路板34、透镜36、反射镜38及保护罩39。第二电路板34、透镜36、反射镜38及保护罩39均可通过螺钉(图未示)固定于灯座22上。反射镜38呈中空圆柱状，面向天花板50设置。保护罩39将反射镜38收容于其内，用于保护反射镜38。第二电路板34和透镜36均位于反射镜38内，透镜36位于第二电路板34上方。
请同时参考图2至图4，透镜36为多面棱柱，包括多个对入射至其上的光实现收敛的出光面360。透镜36靠近第二电路板34的一端形成容置槽362及与容置槽362相贯通的容置孔363。容置槽362用于容置第二电路板34。容置孔363用于容纳LED发光颗粒32，容置孔363呈半圆弧面状，可收敛来自LED发光颗粒32的光。透镜36远离第二电路板34的一端形成凹槽364，凹槽364由多个凹陷的反射面366组合而成，该多个反射面366可以具有相同的形状、相同的曲度，也可以具有不同的形状、不同的曲度，用于将来自LED发光颗粒32以预设角度入射的光全反射至对应的出光面360，光经该出光面360折射后射出，实现光的收敛，其出光角度变小，来自LED发光颗粒32发射的光将被分割成多个光束。如此，入射至相邻两反射面366的光出射后，两光束之间将形成一无光区。
请参考图5及图6，来自LED发光颗粒32的光经出光面360折射后入射至反射镜38，该光经反射镜38多次反射后投射至天花板50上，形成光亮区52。由于入射至反射镜38的两光束之间形成有一无光区，经反射镜38多次反射后投射至天花板50上时，也形成有无光区54，如此，间隔地形成有光亮区52、无光区54，使天花板50上形成辐射状光形，带来美感，达到装饰效果。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本发明，而并非用作为对本发明的限定，只要在本发明的实质精神范围之内，对以上实施例所作的适当改变和变化都落在本发明要求保护的范围之内。
