Abstract
本发明涉及LED技术领域，旨在提供一种坡面LED支架及LED光源。本发明的坡面LED支架的支架表面为LED的封装面，所述封装面为坡面，比如圆锥面，圆台面，棱锥形面或半球形面等；所述坡面还可以在横向设有至少一条以上的LED封装渠，或在坡面表层设LED封装孔。采用本发明支架及LED光源，能突破以往平面形支架在二次反光上的局限性，进一步增强光源亮度；通过单独电路分别控制各条封装渠后形成的LED光源，能产生不同光距的特殊效果。
Description
一种坡面LED支架
技术领域
[0001] 本发明涉及LED技术领域，特别是涉及一种坡面LED支架及LED光源。 背景技术
[0002] 近年来，由于LED发光二极管在亮度等主要技术指标上有了飞速的发展，已广泛 应用于景观照明、大屏幕显示等多种场合。但以往大功率的LED光源，都是在一个平面形支 架上进行多个LED芯片的封装。封装时先将多颗LED芯片排列后一起放置在支架的封装平 面上，再填充环氧树脂或硅树脂等材料加工而成的液态填充剂进行封装作业。如图3所示， 多个LED芯片2在排列后封装在支架5的封装层3内，封装层3的作用是将所有LED发射 出的光均勻化；支架5本身能够形成一个反光面6，反光面6的作用是将LED向四周漫射的 那部分光进行反射；有些支架5还增带有一个反光杯罩4，反光杯罩4的目的是为进一步的 聚光增亮。但是从图中可以发现，由于LED芯片2封装在同一个平面上，经反光面6的作用 后，所有射光都被固定在一定的角度范围内，反光杯罩4起的作用有限，不能完全有效地形 成二次反光，故光源在亮度增强上还没达到最理想的状态。而且，由于在平面支架上的所有 LED与反光面6或反光杯罩4所构成的夹角都是固定和相同的，因此即使各LED的芯片电路 为分别单独控制，但各个LED光线经反射而产成的光距也大致相同，整个LED光源还不能产 生诸如远光近光之类的变化。
发明内容
[0003] 本发明的目的在于克服现有技术中的不足，提供一种坡面LED支架及LED光源，适 用于多组LED大功率的照明场所，如路灯、隧道灯、探照灯等，而且也适用于诸如汽车灯等 之类需要有变换光距功能的照明领域。
[0004] 为了解决上述问题，本发明是通过如下技术方案予以实现：
[0005] 一种坡面LED支架，支架表面为LED的封装面，所述封装面为坡面。

2/3页
条以上的封装渠；LED设在封装渠内；各个封装渠的电路单独控制。
[0015] 与现有技术相比，本发明的有益效果是：
[0016] 1.本发明将LED芯片封装在一种坡面上，形成了立面光源，增大了光射角度。根据 支架造型还可形成各式各样的LED景观光源。
[0017] 2.本发明配套现有的反光杯罩等后，增强二次反光的作用，进而增亮LED光源。经 实验表明，通过二次反光，相同功率的光源，本发明的结构能提高光源亮度5-10倍。
[0018] 3.由于各个封装渠不在同一平面上，与反光杯罩所构成的反光角度不同，因此封 装渠采用分路控制后，每条封装渠发光经反射后产生的光距不同，同一光源因此能产生远 光和近光的变化，可适用于汽车灯等的照明领域。
[0019] 4.支架体为高导热的金属与陶瓷材料复合制成，内部空心，既节省材料，又利于光 源的散热。

具体实施方式
[0025] 下面结合附图和具体实施例对本发明作进一步详细的描述：
[0026] 如图1所示，本发明中坡面LED支架的支架体为一个无头圆锥体，圆锥体中空，围 绕圆锥体的表面横向设有2条环状的LED封装渠1，封装渠1的底面为LED封装面，封装渠1 的渠壁呈外倾角，形成LED的反光面；整个LED支架为金属材料或金属陶瓷复合材料制成， 比如用铜、铝，或这类高导热的金属与陶瓷材料复合制成。
[0027] 图2是本发明的一种带坡面LED支架的LED光源，其支架为上例所述的带圆锥坡 面的支架。支架的底坐与一个反光杯罩4相连。LED芯片2设在封装渠1的底面上，用封装 层3填充保护；封装渠1的渠壁呈外倾角，构成这道LED光槽的反光面。各个封装渠1的电 路单独控制，根据亮度需要，这2条封装渠1所形成的LED光槽可以同时点亮，也可以分开 单独点亮。由于各个封装渠1不在同一平面上，与反光杯罩4所构成的反光角度不同，因此 封装渠1采用分路控制后，每条封装渠1发光经反射后产生的光距不同，同一 LED光源因此 能产生远光和近光的变化，可适用于汽车灯等的照明领域。而且由于反光杯罩4能完全起 到二次反光的作用，因此整个LED光源可增亮5-10倍。
[0028] 图3是传统的平面形LED支架的结构示意图。图中可看出，在LED支架5中的处 在封装层3下方的LED芯片2，由于都处于同一个水平面上，因此所发射的光线在经反光面 6的作用后，形成的角度使得反光杯罩4很难再起到二次反光的作用，因此整个光源增亮的 效果欠佳。
[0029] 图4是本发明坡面LED支架的另一种具体实施例图，其支架体为一个圆锥体，圆锥 体的坡面表层上均布设有LED的封装孔7，用来封装各个LED发光二极管。封装孔7的四壁呈外倾角，构成LED的反光面。整个LED支架材料为金属材料或金属陶瓷复合材料制成，内 部可以为中空结构。
[0030] 最后，还要注意的是，以上列举的仅是本发明的若干个具体实施例。显然，本发明 还可以有许多变形，比如支架形状还可以为圆柱体、金字塔形、钻石形等多种变形。本领域 的普通技术人员能从本发明公开的内容直接导出或联想到的所有变形，均应认为是本发明 的保护范围。
