Description

一种可偏转角度的嵌入式 LED灯具的圆弧散热装置
技术领域
本实用新型涉及照明灯具的技术领域, 尤其是指一种可偏转角度的嵌入式 LED灯具的圆弧散热装置。
背景技术
在当今全球能源紧缺的大环境下, 世界各国都大力倡导节能减排, 其中, LED灯具以节能, 环保等优点赢得了人们的喜爱, 但是, LED灯具的散热问题一 直是个难题。 传统的灯具散热方式是将光源产生的热量沿连接轴传递到灯架上, 再通过灯架将热量自然散发到空气中, 从而使灯具降温。 在这种散热方式中, 灯架参与散热的作用并不明显, 这样往往不能使热量充分散发, 且散热速度慢, 增加了灯具的能耗, 缩短了灯具的使用寿命。 而一些装有散热器的 LED灯具往 往体积不够小巧, 适用范围不够广泛。
发明内容
本实用新型的目的在于克服现有技术的不足, 提供一种设计合理可靠、 散 热性能好、 体积小的可偏转角度的嵌入式 LED灯具的圆弧散热装置。
为实现上述目的, 本实用新型所提供的技术方案为:、 一种可偏转角度的嵌 入式 LED灯具的圆弧散热装置, 它包括灯架、 可偏转角度的内环组件、 扩光板、 LED光源, 其中, LED光源内置于可偏转角度的内环组件, 扩光板安装在可偏转 角度的内环组件的环口上, 可偏转角度的内环组件与灯架配合安装, 其特征在 于: 灯架的内底和可偏转角度的内环组件的底部均为弧面, 且两弧面始终贴合 装配。
所述的两弧面为球圆弧面或半弧面。
所述的灯架的内底为凹圆弧面, 可偏转角度的内环组件的底部为凸圆弧面。 所述的灯架的内底为凸圆弧面, 可偏转角度的内环组件的底部为凹圆弧面。 所述的灯架内壁侧有固定的压块, 且通过压块使所述的两圆弧面始终贴合。 所述的压块通过螺钉固定在灯架内壁侧上。
所述的灯架侧壁分别插入处于同一轴线并套有套件的螺钉, 且通过螺钉使 灯架和可偏转角度的内环组件的侧弧面连接。
所述的内环组件的侧弧面上均有枢轴连接孔, 所述的灯架侧壁分别插入处 于同一轴线的沉头螺丝, 沉头螺丝作为枢轴与可偏转角度的内环组件侧弧面上 的枢轴连接孔对应插入连接。
本实用新型在采用了上述方案后, 其最大优点在于将可偏转角度的内环组 件的底部和灯架的内底设计成圆弧面, 且两圆弧面完全贴合连接, 让灯具散热 接触面积大大增加, 使灯具散热速度快, 散热效果好, 并降低了灯具的能耗, 达到了 LED灯具高功率、 高流明数的要求, 同时, 这种嵌入式设计还有助于减 小灯具的体积, 增大 LED灯具的适用范围。
