背景技术
[0002] 现在的顶置照明灯具的光源多采用数个平行设置的灯管,作为对传统灯具的改进,现在已经出现了以LED作为光源的照明灯具。
[0003] 但是目前的LED灯具与传统灯管灯具的差别仅在于光源不同,并没有充分考虑到LED的各种特性,另一方面,由于LED光源相互之间也存在 一定的间距,因此在使用时,光照也会出现光线不连续或不均匀的现象,即在LED光源之间也存在暗区,从而影响照明效果。
发明内容
[0004] 本发明提供一种顶置LED照明灯具,以解决照明效果不佳的问题。
[0005] 为解决上述技术问题,本发明提供一种顶置LED照明灯具,包括灯罩,并采用多颗LED作为光源,还包括位于灯罩内的反光装置,所述反光装置包括若干相邻设置的反光单元,所述反光单元具有开口朝向受光面的上凹的容纳空间,所述容纳空间的内表面均为反光面,所述LED设置在所述容纳空间内。
[0006] 优选的,所述多颗LED按网格阵列排列。
[0007] 优选的,所述反光单元为倒置的棱锥台形。
[0008] 优选的,其特征在于,所述反光单元的侧壁外凸或内凹。
[0009] 优选的,所述LED设置在所述反光单元的底面或侧面上。
[0010] 优选的,所述LED光源下方进一步设置有匀光装置,所述匀光装置对应于所述LED的位置具有遮光结构。
[0011] 优选的,所述LED阵列排列,所述匀光装置为经纬编织的网格板,所述遮光结构为与所述LED对应的所述网格板的交叉点。
[0012] 优选的,所述网格板的交叉点上设有半透明遮光片、凹透镜或凸透镜。
[0013] 优选的,所述匀光装置为半透明板,所述遮光结构为在所述半透明板上形成的与所述LED对应的黑色丝网状图案、凹透镜结构或凸透镜结构。
[0014] 本发明利用反光装置和匀光装置很好的解决了照明的均匀性与连续性,改善了照明效果。

[0028] 图14为图13的侧视图。
具体实施方式
[0029] 下面参照附图对本发明进行详细说明。
[0030] 参照图I和图2为本发明的一个实施例示意图。顶置LED照明灯具首先包括灯罩(图中未示出),以及位于灯罩内的由多颗LED 2组成的光源,此外,为了增加整体照明亮度,本发明还包括一个反光装置,如图I所示,反光装置设置在灯罩内,反光装置由若干相邻设置的反光单元I组成,反光单元I具有开口朝向所述画片支撑板的上凹的容纳空间,容纳空间的内表面均为反光面,LED设置在所述容纳空间内。在本例中,采用光照角度为160度的LED 2,在其他实施例中,根据需要也可采用其它光照角度的LED,例如120度。所述上凹的容纳空间可以是通过一个锥棱台或圆柱台形的顶面上凹实现,本发明对此不作限制。
[0031] 具体来说,反光装置可以包括多个开口部边缘相互连接在一起的倒置的四棱锥台形(也可以是三棱锥台、四棱锥台或五棱锥台等锥棱台形)的反光单元I。四棱锥台形的反光单元的内表面,即内侧面和底面均为反光面,LED对称地设置在所述反光单元的底面或侧面上,在此例中,LED 2设置在反光单元内底面的对称轴上,如图2所示。
[0032] 图3和图4为本发明的反光装置的另一个实施例。在此例中,反光装置与上例中的反光装置相同,都是包括多个开口部边缘相互连接在一起的倒置的四棱锥台形的反光单元I。不同之处在于LED 2设置在反光单元内底面的四个角上,如图4所示。
[0033] 图5和图6为本发明的反光装置的另一个实施例。在此例中,反光装置还是包括多个开口部边缘相互连接在一起的倒置的四棱锥台形的反光单元I。LED 2分别对称地设置在反光单元的内侧棱边的两侧,如图6所示。
[0034] 图7和图8为本发明的反光装置的另一个实施例。在此例中,反光装置包括多个开口部边缘连接在一起的倒置的四棱锥台形的反光单元1,不同的是,该反光单元I的侧壁外凸。LED 2设置在反光单元I的内底面的对称轴上,如图8所示。
[0035] 图9和图10为本发明的反光装置的另一个实施例。在此例中,反光装置包括多个开口部边缘连接在一起的倒置的四棱锥台形的反光单元1,不同的是,该反光单元I的侧壁内凹。LED 2设置在反光单元I的内底面的对称轴上,如图10所示。
[0036] 图11和图12为本发明的反光装置的另一个实施例。在此例中,反光装置包括多个开口部边缘连接在一起的倒置的四棱锥台形的反光单元1,不同的是,该反光单元I的侧壁外凸。LED 2设置在反光单元I的各内侧面的中心位置,如图12所示。
[0037] 图13和图14为本发明的反光装置的另一个实施例。在此例中,反光装置包括多个开口部边缘连接在一起的倒置的四棱锥台形的反光单元1,不同的是,该反光单元I的侧壁内凹。LED 2设置在反光单元I的各内侧面的中心位置,如图14所示。
[0038] 此外,为进一步使光线更加均匀,本发明还可以在所述画面支撑板与LED之间设置一个匀光装置,所述匀光装置对应于所述LED的位置具有遮光结构,以对LED照射出来的光线进行遮挡,或进一步向四周疏导,使光线柔和均为的照射到画面展示板上。
[0039] 例如,当所述LED阵列排列时,所述匀光装置为经纬编织的网格板,所述遮光结构为与所述LED对应的所述网格板的交叉点。
[0040] 在所述网格板的交叉点上还可以设有半透明遮光片、凹透镜或凸透镜。
[0041] 所述匀光装置还可以是为半透明板,所述遮光结构为与所述LED对应的印制于所述半透明板上的黑色丝网状图案。所述遮光结构还可以是在所述半透明板上形成的与所述LED对应的凹透镜结构或凸透镜结构。 [0042] 这些均光装置的具体结构实现简单,成本低廉,遮光及导光的效果好。
[0043] 前面描述的仅为本发明的具体实施方式,本发明并不仅限于此,任何关于本发明的变体或对其所进行的改进以及调整都在本发明所要求保护的范围之内。
