[0036] 进一步地， 所述陶瓷灯头 20的外表面上对应于所述第一腔室 231位置设有防滑 纹。 设置防滑纹 211， 增加摩擦， 以便于操作该 R7s线性光源 100。 具体地， 防滑 纹 211可以为螺纹槽， 也可以为其它纹路。 另外， 防滑纹 211也可以使该 R7s线性 光源 100的外观更为美观。
[0037] 进一步地， LED灯板组件 40缠绕于陶瓷柱 10上。 这种结构可以方便陶瓷柱 10支 撑住 LED灯板组件 40， 同吋陶瓷柱 10能帮助 LED灯板组件 40进行更好的散热， 还 可以实现多角度发光， 如 360度发光。 在另一些实施例中， LED灯板组件 40粘结 于陶瓷柱 10上， 安装方便及控制发光角度。 当然， 如果 LED灯板组件 40周向均安 装有 LED灯珠 42吋， 可以实现 360度发光。 [0038] 进一步地， 灯罩 50为玻璃罩或塑料罩。 当然， 灯罩 50还可以为其它材料制作的 透光罩。
[0039] 进一步地， 两个导电端子 30之间的距离范围为 76mm-254mm， 从而可以使得该
R7s线性光源 100的长度范围在 76mm-254mm之间。
[0040] 进一步地， LED灯板组件 40包括柔性基板 41和安装于柔性基板 41上的 LED灯珠
42。 使用柔性基板 41， 可以方便进行折弯， 以便更好的配合贴在陶瓷柱 10上， 使 LED灯珠 42发出的热量可以快速传导至陶瓷柱 10， 并经陶瓷柱 10散出。
[0041] 进一步地， 柔性基板 41为铝基板或铜基板。 使用铝基板或铜基板， 可以起到良 好的导电作用， 同吋也可以提高散热效率。 当然在其它一些实施例中， 柔性基 板 41也可以为塑料基板。
[0042] 以上所述仅为本实用新型的较佳实施例而已， 并不用以限制本实用新型， 凡在 本实用新型的精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含 在本实用新型的保护范围之内。
