[0032] 如图 7所示, 每根金属编织带 15的两端端头相互贴合, 使金属编编织带 15上形 成圈形散热部 23, 每根金属编织带 15的两端端头均与导热热管 13的后端通过铜 环 24压合固定, 所述金属编织带 15优选为三个, 从左到右依次顺序排列, 圈形 散热部 23的孔竖向设置。
[0033] 如图 8所示, 灯体 1和套接部 16还可以采用两个轴对称的左灯壳 41和右灯壳 42构 成, 左灯壳和右灯壳的横截面均为半圆形; 左灯壳和右灯壳的后端均设有构成 完整的套接部 16的半圆形凸起 43, 而在左灯壳 41和右灯壳 42内设有构成灯体内 孔 10的第一半圆形孔 46, 而位于半圆形凸起 43内则设有构成套接部内孔 17的第 二半圆形孔 44, 左灯壳 41和右灯壳 42对合后, 两个第一半圆形孔 46就构成了完 整的灯体内孔 10, 而两个第二半圆形孔 44构成了完成的, 所述左灯壳 41和右灯 壳 42采用铝合金材料制成, 在左灯壳和右灯壳的前端设有前帽 45, 贯穿孔 20由 设于半圆形凸起 43后端面上的第三半圆形孔 47组成。
[0034] 根据反光杯 31的后端与总成盖 34之间的距离的不同, 在安装吋, 波纹管体 7会 根据距离的不同, 而如图 4和图 5所示, 进行收缩或拉伸, 从而实现满足不同距 离的使用。
[0035] 本发明通过设置铝合金外壳、 铜基板、 导热热管、 金属编织带有效的解决了灯 具积热散热问题, 热量从 LED光源发出, 经过铜基板传输到导热热管, 导热热管 跟金属编织带压合在一起, 金属编织带通过每跟铜丝把热量最终散热出去, 提 高了散热效果; 防水圈解决了反光杯与总成盖之间距离不同的防水、 防尘的要 求。 头灯灯具用固定灯具卡簧固定在反光杯上, 因不同的总成盖有长短之分, 使得灯具无法安装进总成盖内, 如破坏钻孔方式又不能起到防水、 防尘作用。 采用可伸缩的防水圈, 能控制长短, 在总成盖上钻孔的方式安装上弹簧型防水 圈, 有效的解决了不同总成盖的防水、 防尘问题。
