Description

一种LED灯散热灯体
所属技术领域
本实用新型涉及一种LED灯散热灯体制造技术，通过散热灯体基体散热的灯体结构、材质和制造工艺。
背景技术
随着环保节能LED灯的使用范围越广，亮度要求越高，体积越小，集成化程度不断提高，随之而来产生的热量也越来越大。如何将LED灯产生源源不断的热量快速导散开，使LED灯能在要求内的温度内正常工作，产品散热问题已经成为制约其性能体现和发展的重要障碍。现有技术使用的铸铝散热灯体已无法满足使用的要求，如铸造散热灯体的传输速度和散热面积不够。要满足散热量需增加散热灯体的体积，而散热灯体的体积又受到使用空间的限制。
实用新型内容
为克服现有技术中使用的铸造散热灯体散热量等不足的技术问题，本实用新型对散热灯体的结构、材质和制造工艺进行改进。
本实用新型解决其问题采用的技术方案是：按照半导体LED元件需要使用功耗，使用空间体积和工作环境要求，计算得出散热灯体的体积和散热翅片面积。综合上述数据计算得出铝挤压散热灯体的整体形状，通过一次铝挤端面成型的散热灯体结构，包括：散热灯体基体、散热灯体基体上均部设置的散热翅片、导线孔等，二次加工达到使用体积和外观要求。
本实用新型的有益效果是：散热面积大，散热灯体体积小，散热量高，制造成本低，外形美观，使用寿命长，本实用新型实施例经实验证明，在4W或7W以上LED灯上使用本实用新型的散热灯体，比使用同体积传统铸铝散热灯体LED灯核心温度可降低14度以上，LED灯工作效率可提高30％，寿命可提高40％。
附图说明

附图2为本实用新型散热灯体基体实施例2侧视结构结构示意图。
附图3为本实用新型散热灯体基体实施例1横截面结构结构示意图。
附图4为本实用新型散热灯体基体实施例2横截面结构结构示意图。
附图中，1、散热灯体基体，2、散热翅片，3、电路铝基板，4、灯罩连接卡槽，5、电源连接卡槽，6、导线孔，7、圆芯，8、LED灯电源，9、发光LED元件，10、LED灯聚光罩。
具体实施方式
参看附图1，LED灯一次端面成型散热灯体，包括：散热灯体基体1、散热灯体基体1上均部设置的散热翅片2、用于固定聚光保护罩的卡槽4和散热灯体基体1内设置的圆芯7，电源连接卡槽5和导线孔6。
散热灯体基体1和散热灯体基体1上均部设置的散热翅片2是由铝合金材料一次挤压成型，本实用新型采用上述结构及材料和制造工艺，提高了散热灯体的制造精度和散热灯体基体1的散热效果。以散热灯体基体1的中心呈扇形或涡轮形设置，散热灯体基体1二次加工后达到使用体积和外观要求，其侧视外观形状可根据需要加工成多种形状，如：杯形、圆柱形、梯形等。
散热灯体基体1圆芯7内横向过盈塞入底端封口电路铝基板3作为空心端面封口，使圆芯7形成盲孔，封口铝板或有电路铝基板3轴向面与散热灯体基体1圆芯7紧密结合形成整体的LED灯散热灯体。电路铝基板3接触LED元件9，达到LED元件9的热量被整体的LED灯散热灯体快速吸收和散热目的。
在散热灯体基体1上有固定聚光保护罩的卡槽4，用于连接固定LED灯聚光罩10。在散热灯体基体1顶端上有固定电源8的卡槽5，在散热灯体基体1内有导线孔6，用于LED元件9连接线通过和电源8接触。散热灯体基体1、LED电源8和LED灯聚光罩10，通过卡槽5、4紧固连接形成整体产品LED照明灯。
本实用新型LED灯散热灯体使用时，散热灯体基体1底端封口电路铝基板3面与LED元件9热源接触，热量迅速由散热灯体基体1内电路铝基板3吸收热量并传递给散热灯体基体1上散热翅片2的散热传导过程。
所述的散热灯体基体1底端电路铝基板3面与顶端之间有一导线孔6，用于LED元件9连接线通过和电源8接触。
本实用新型实施实例根据实际使用需要，散热灯体基体1上均部设置的散热翅片2，围绕散热灯体基体1的散热翅片2呈扇形设置或以散热灯体基体1的中心呈涡轮形设置。
本实用新型为便于散热灯体基体1的加工制造，散热灯体基体1中心圆芯7为空心，圆芯7可根据需要选择塞入底端封口铝板或电路铝基板3，电路铝基板3与LED元件9接触，将LED元件9连接线穿过导线孔6与LED电源8接触连接，电源8与散热灯体基体1通过散热灯体基体1上的卡槽5相固定连接。最后再将LED灯聚光罩10紧卡在散热灯体基体1的卡槽4内，达到整体紧固成型的产品效果。
