Abstract

本发明公开了一种LED光源模组，包括LED光源、荧光粉片和设于荧光粉片远离LED光源一侧的光阑，荧光粉片的尺寸与LED光源对应，光阑的中部设有与LED光源的内切圆对应的圆形通孔，光阑采用不透光的散热材料制成。由于荧光粉片的尺寸与LED光源的尺寸一致，圆形通孔的尺寸与LED光源的内切圆的尺寸对应，使LED光源经过荧光粉片激发出的光线由圆形通孔处出射，光线集中，发散角度小，即LED光源和荧光粉片构成一个点光源，可以大大提高中心照明亮度和距离，满足远光场的照明需求。光阑采用不透光的散热材料制成，一方面防止光线从圆形通孔外侧泄露，另一方面可以将荧光粉片上产生的热量迅速散热出去，避免热量过高而烧坏荧光粉片，提高其使用寿命。

LED光源模组
技术领域
本发明涉及照明领域，具体涉及一种LED光源模组。
背景技术
随着半导体技术的发展，LED(Light Emitting Diode，发光二极管)光源因具有高效，节能，环保、成本低以及寿命长等优点，正逐步取代传统的白炽灯和节能灯，成为一种通用的照明光源。
LED(Light Emitting Diode；发光二极管)是一种能够将电能转化为可见光的固态的半导体器件，具有寿命长、能耗低等优点，随着LED技术的发展，LED光源的性能也越来越好。现有的LED灯通常采用LED光源激发荧光粉之后形成白光，这种现有的LED灯通常存在光线发散角度大，光线不够集中，从而导致亮度不高的问题，未能满足高亮度以及远距离的照明需求。
发明内容
本发明提供了一种LED光源模组，以解决现有技术中存在的LED灯发散角度大，光线不够集中，未能满足高亮度以及远距离照明。
为了解决上述技术问题，本发明的技术方案是：一种LED光源模组，包括LED光源、荧光粉片和设于所述荧光粉片远离所述LED光源一侧的光阑，所述荧光粉片的尺寸与所述LED光源对应，所述光阑的中部设有与所述LED光源的内切圆的尺寸对应的圆形通孔，所述光阑采用不透光的散热材料制成。
进一步的，所述荧光粉片为与所述LED光源尺寸对应的矩形结构。
进一步的，所述荧光粉片为圆形结构，尺寸与所述圆形通孔对应。
进一步的，还包括设于所述光阑后方的聚焦透镜，所述荧光粉片与所述聚焦透镜之间的距离大于所述聚焦透镜的焦距。
进一步的，还包括包设于所述LED光源和荧光粉片外周的封装层。
进一步的，所述封装层的内壁设有反射层。
进一步的，所述LED光源为蓝光LED，所述荧光粉片为黄色荧光粉片。
进一步的，所述散热材料为金属铜或石墨。
进一步的，所述光阑以镀膜的方式固定于所述荧光粉片上。
本发明提供的LED光源模组，包括LED光源、荧光粉片和设于所述荧光粉片远离所述LED光源一侧的光阑，所述荧光粉片的尺寸与所述LED光源对应，所述光阑的中部设有与所述LED光源的内切圆的尺寸对应的圆形通孔，所述光阑采用不透光的散热材料制成。由于荧光粉片的尺寸与LED光源的尺寸一致，光阑的中部设有尺寸与所述LED光源的内切圆的尺寸对应的圆形通孔，因此LED光源经过荧光粉片激发出的光线由圆形通孔处出射，光线集中，发散角度小，即LED光源和荧光粉片构成一个点光源，可以大大提高中心照明亮度和距离，满足远光场的照明需求。另外，光阑采用不透光的散热材料制成，一方面防止光线从圆形通孔外侧泄露，另一方面可以将荧光粉片上产生的热量迅速散热出去，避免热量过高而烧坏荧光粉片，提高其使用寿命。

具体实施方式
下面结合附图对本发明作详细描述：
如图1-3所示，本发明提供了一种LED光源模组，包括LED光源10、荧光粉片20和设于所述荧光粉片20远离所述LED光源10一侧的光阑30，所述荧光粉片20的尺寸与所述LED光源10对应，所述光阑30的中部设有与所述LED光源10的内切圆的尺寸对应的圆形通孔310，所述光阑30采用不透光的散热材料制成。具体的，这里的LED光源10是指LED芯片，现有的LED芯片均为矩形结构，LED光源10发出的光线投射到荧光粉片20上激发出荧光，并从光阑30的圆形通孔310处出射，所述荧光粉片20的尺寸与所述LED光源10对应，即LED光源10的尺寸相近或不大于所述LED光源10的尺寸，圆形通孔310的尺寸与LED光源10的内切圆的尺寸对应，即圆形通孔310的直径与所述LED芯片的短边一致，或者略小于LED芯片的短边，光阑30采用不透光的散热材料制成，一方面防止光线从圆形通孔310外侧泄露，另一方面可以将荧光粉片20上产生的热量迅速散热出去。由于荧光粉片20的尺寸和圆形通孔310的尺寸与LED光源10的尺寸一致，因此LED光源10经过荧光粉片20激发出的光线由圆形通孔310处出射，光线集中，发散角度小，即LED光源10和荧光粉片20构成一个点光源，可以大大提高中心照明亮度和距离，满足远光场的照明需求。
优选的，所述荧光粉片20为与所述LED光源10尺寸对应的矩形结构，如图2所示，此时荧光粉片20与LED光源10的结构尺寸一致，光阑30固定于荧光粉片20的四周边缘，两者通过粘接固定。
优选的，所述荧光粉片20为圆形结构，尺寸与所述圆形通孔310对应，即所述荧光粉片20的直径与所述LED光源10的内切圆的直径对应，即不大于LED芯片的短边，如图3所示，此时光阑30中的圆形通孔310与荧光粉片20的大小对应，荧光粉片20可以嵌设于光阑30的圆形通孔310中，且保证紧密贴合，避免光线泄露出去。
优选的，所述LED光源模组还包括设于所述光阑30后方的聚焦透镜40，所述荧光粉片20与所述聚焦透镜40之间的距离大于所述聚焦透镜40的焦距，从而使荧光粉片20激发出的荧光经过聚焦透镜40后形成聚焦的照明光束，进一步提高光线的亮度。
优选的，所述LED光源模组还包括包设于所述LED光源10和荧光粉片20外周的封装层50，通过封装层将LED光源10和荧光粉片20封装在一起，同时也避免LED光源10发出的光线泄漏出去。优选的，所述封装层50的内壁设有反射层，用于将投射到封装层50上的光线反射到荧光粉片20上，提高光线利用率。
优选的，所述LED光源10为蓝光LED，所述荧光粉片20为黄色荧光粉片，LED光源10发出蓝色的光束经荧光粉片20激发从而产生白色的荧光。当然LED光源10和荧光粉片20也可以采用其他的组合，此处不予限定。
优选的，所述散热材料为金属铜或石墨，导热系数高，导热效果好，可以迅速将荧光粉片20上产生的热量快速散发出去。
优选的，所述光阑30以镀膜的方式固定于所述荧光粉片20上。采用该种方式不仅降低了结构复杂度，提高了制作便捷度，且大大提高了光源模组的稳定性。
综上所述，本发明提供的LED光源模组，包括LED光源10、荧光粉片20和设于所述荧光粉片20远离所述LED光源10一侧的光阑30，所述荧光粉片20的尺寸与所述LED光源10对应，所述光阑30的中部设有与所述LED光源10的内切圆的尺寸对应的圆形通孔310，所述光阑30采用不透光的散热材料制成。由于荧光粉片20的尺寸与LED光源10的尺寸一致，圆形通孔310的尺寸与LED光源10的内切圆的尺寸对应，因此LED光源10经过荧光粉片20激发出的光线由圆形通孔310处出射，光线集中，发散角度小，即LED光源10和荧光粉片20构成一个点光源，可以大大提高中心照明亮度和距离，满足远光场的照明需求。另外，光阑30采用不透光的散热材料制成，一方面防止光线从圆形通孔310外侧泄露，另一方面可以将荧光粉片20上产生的热量迅速散热出去，避免热量过高而烧坏荧光粉片20，提高其使用寿命。
虽然说明书中对本发明的实施方式进行了说明，但这些实施方式只是作为提示，不应限定本发明的保护范围。在不脱离本发明宗旨的范围内进行各种省略、置换和变更均应包含在本发明的保护范围内。
