Description
本发明涉及一种照明技术领域，更具体地说，它涉及一种高效散热的LED陶瓷灯杯及其制备方法。
LED具有节能、环保、安全、使用寿命长、高亮度、易调光等优良特点，可以广泛应用于各种指示、显示、装置、背光源和普通照明领域中。在LED发展初期，主要用于小功率照明或者装饰中，其散热性能跟跟功率匹配，不会出现散热问题。但是，现在LED越来越多的应用在大功率领域中，因此，散热问题是LED发展的一个主要目标。
LED陶瓷灯的散热性能是评价LED陶瓷灯性能的一个重要指标，并且其散热性能也主要决定LED陶瓷灯的使用寿命长短，因此，LED陶瓷灯散热器是LED陶瓷灯的一个重要部件。因此，现在LED陶瓷灯的发展方向都是怎样提高它的散热效率。
传统的LED散热器主要采用铝才来作为散热器，同时散热器是与灯罩卡接的，虽然铝材作为LED陶瓷灯散热器的散热效果较好，但是铝材料成本高，再者铝材料的加工成本也高，导致目前大功率LED产品价格相对较高。随着技术的发展，现在也有铜散热器或者采用水冷或风冷等一些辅助手段来散热，但是这些散热器要么结构复杂，要么成本高，无法适应降低成本提高散热性能的前提下来应用到LED陶瓷灯中。
发明内容

作为优选，所述本体横截面积较小的一端为固定部，所述固定部上设置有螺纹，所述灯头与固定部螺纹连接。
作为优选，所述固定部上设置避免导线压断的导线孔。
作为优选，制备权利要求LED陶瓷灯的方法，包括以下步骤：
(1)备料：按照陶瓷散热器用的陶瓷材料配方准备各组分，按质量百分比计，所述陶瓷材料包括：85-90％的氧化铝，0.5-1.5％二氧化硅，1.5-3.5％碳酸钙，1.0-3.0％高岭土，5-7％的造孔剂；
(2)处理材料：将步骤(1)中准备的各个组分材料烘干，然后再按照配方中的含量称取和混合到一起，再将混合均匀的材料研磨均匀；
(3)成型：将步骤(2)中的材料在注浆机中和模具配合注浆后在300-400度的烘箱中烘干成型，制成陶瓷灯杯。
作为优选，步骤(1)中所述所述陶瓷材料包括：90％的氧化铝，1.5％二氧化硅，3.0％碳酸钙，1.0％高岭土，5％的造孔剂。
作为优选，步骤(2)中将材料烘干至含水率低于0.05％，将材料研磨粒径低于20μm。
通过采用上述技术方案，本发明中散热棱格直接与灯罩和散热器之间的空腔连通，散热棱格将空腔中的高热空气带走，起到了降温的作用，具有良好的散热效果，同时其增加了散热器与空气的接触面积，提高了散热器的散

图1为本发明的结构示意图；
图2为本发明的局部剖面示意图。
图中：0、本体；1、散热格棱；11、散热孔；2、放置面；21、通孔；22、翻边；3、螺纹；31、导线孔；4、固定部。
参照图1至图2对本发明的实施例做进一步说明。
如图1所示，一种高效散热的LED陶瓷灯杯，包括其本体0，该本体0呈杯型，本体0具有横截面积一大一小两个端面，大端向下凹陷形成放置面2，放置面2的中心位置向下形成通孔21,通孔21是沿本体0的轴向贯穿设置的，该种陶瓷灯杯采用LED作为发光源，LED一般是焊接或贴在PCB板上的，设置有LED光源的PCB板设置在放置面2上，且通过胶粘等方式与放置面2固定；散热器与灯罩卡接的一端向内凹陷形成放置面2，放置面2与本体0的内壁形成有供灯罩卡接的翻边22；而通孔21是用于供PCB板上的导线穿设的，导线的一端与设置在放置面2上的PCB板连接，导线的大部分穿设过通孔21，从而与设置在通孔21下方的灯头连接；同时本体0横截面积较小的一端设置有螺纹3，灯头与本体0螺纹3配合，从而灯头与本体0固定连接，本发明中的灯头结构如申请号为“201110264489.X”的发明专利中公开的灯头，该专利中，灯头与底座通过打点固定，打点固定是一种类似于胶粘或者铆接的固定方式，因为胶水在受热后会发生融化，固定效果会变差，所以在本体0横截面积较小的一端设置有螺纹3，本体0通过螺纹3与灯头连接，无需胶粘，通过机械的方式起到了固定效果，不会受到灯头发热的影响，连接的更加稳定。
如图1所示，本体0横截面积较小的具有螺纹3的一端为固定部4，螺纹3设置在固定部4上，固定部4上还设置有导线孔31，导线孔31位于螺纹的范围内，该导线孔31呈镜像的Z字形状，灯头的底部与PCB板的火线连
接，灯头的侧面与PCB上的零线连接，然而本体0是由陶瓷制成的，而且陶瓷是不导电的，所以PCB板的零线无法与灯头的侧壁导通，故设置有导线孔31解决该问题，导线穿设过导线孔31后即可与灯头的侧壁导通，从而产生电流回路，但是灯头在安装时候须先与导线焊接，如果将灯头旋入本体0将会导致导线与灯头的连接位置的断裂，所以在本体0较小的一端设置有导线孔31，导线孔31的走向是沿着螺纹3孔的旋转方向倾斜向上的，从而当灯头发生旋转时，导线也跟随在导线孔31内旋转不会发生折断问题。
如图1和图2所示，本体0上若干散热格棱1，散热格棱1呈旋风状排布，散热格棱1包括三个散热面，所述散热面内陷于所述本体0的外表面，散热格棱1的一端为散热孔11，散热格棱1的另一端露出所述本体0的外表面，流经本体0上的风经过旋风状的排布的散热格棱1被引入灯罩内，旋风状的散热格棱1加快了空气的流动速度，然后空气被散热孔11带入灯罩内，从而LED在灯罩内产生的热量又被从不断进入灯罩内的风带出，从而降低灯罩内的热量。
实施例1
本实施例中，制备以上上述的高效散热的LED陶瓷散热器的方法，包括以下几步：
(1)备料：按照陶瓷散热器用的陶瓷材料配方准备各组分，按质量百分比计，上述陶瓷材料包括：85％的氧化铝，0.5％二氧化硅，3.5％碳酸钙，1.0％高岭土，1.0％的造孔剂。
(2)处理材料：将(1)中准备的各个组分材料烘干，然后再按照配方中的含量称取和混合到一起，再将混合均匀的材料研磨均匀；在该步骤中，测量烘干后的材料的含水率，含水率要低于0.03％，研磨后材料的粒径为18μm。
(3)成型：将步骤(2)中的材料在注浆机中和模具配合注浆成型，然后在300度的烘箱中烘干成型，制成陶瓷散热器。

本实施例中，制备以上上述的高效散热的LED陶瓷散热器的方法，包括
以下几步：
(1)备料：按照陶瓷散热器用的陶瓷材料配方准备各组分，按质量百分比计，上述陶瓷材料包括：87％的氧化铝，0.5％二氧化硅，1.5％碳酸钙，3％高岭土,6％造孔剂。
(2)处理材料：将(1)中准备的各个组分材料烘干，然后再按照配方中的含量称取和混合到一起，再将混合均匀的材料研磨均匀；在该步骤中，测量烘干后的材料的含水率，含水率为0.01，研磨后材料的粒径为19μm。
(3)成型：将步骤(2)中的材料在注浆机中和模具配合注浆成型，然后放入350度的烘箱中烘干成型，制成陶瓷散热器。
实施例3
本实施例中，制备以上上述的高效散热的LED陶瓷散热器的方法，包括以下几步：
(1)备料：按照陶瓷散热器用的陶瓷材料配方准备各组分，按质量百分比计，上述陶瓷材料包括：90％的氧化铝，1.5％二氧化硅，2.5％碳酸钙，1％高岭土,5％的造孔剂。
(2)处理材料：将(1)中准备的各个组分材料烘干，然后再按照配方中的含量称取和混合到一起，再将混合均匀的材料研磨均匀；在该步骤中，测量烘干后的材料的含水率，含水率为0.01，研磨后材料的粒径为19μm。
(3)成型：将步骤(2)中的材料在注浆机中和模具配合注浆成型，然后放入400度的烘箱中烘干成型，制成陶瓷散热器。
按以上三种配方和实施步骤，各制作100个进行检测，其测试结果如下表所示：
本发明中，当氧化铝的含量高于90％时，将会导致本体的比热容变大，不利于散热，散热效果变差，当氧化铝的含量低于85％时，将会导致本体的结构强度大大降低；当二氧化硅的含量高于1.5％时，将会导致本体的散热性能变差，当二氧化硅的含量低于0.5％时，将会导致本体的耐温效果变差；1.0-3.0％高岭土；当高岭土的含量低于1％时，各组分之间的粘结性能变差，长时间使用后，本体上会掉落二氧化硅或者氧化铝的粉料，同时当高岭土的含量高于3.0％时，将会导致本体在烘干烧结时，高岭土过度收缩，成品率变低。同时，造孔剂在300-400度的低温烧结中发生气化，然后在本体内部产生气孔，气孔能增加本体与空气的接触面积，利于散热。
本发明的陶瓷散热器，在陶瓷材料中添加氧化铝能够提高散热效率，并且在散热器本体的外周设有旋风状的散热格棱，增加了散热表面积，提高了散热效率。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
