Description
带散热通风系统的LED路灯
技术领域
[0001] 本实用新型涉及道路照明灯具领域，尤其涉及采用LED为光源的大功率路灯。 背景技术
[0002] 随着城市建设的发展，道路建设日益完善，照明路灯在城市照明体系中所占的比 重越来越大，同时与供电紧张的矛盾也越发突出，采用新的照明路灯来代替现有路灯的要 求便更加迫切。而LED作为一种新的照明技术存在很大的优势，其具有工作寿命长、发光效 率高、省电等优点。但是其发光机理决定了 LED的功率不可能很高。因此，LED路灯的应用 基本都是在一个LED基板上分布多个LED，从而实现较高功率的照明需要。然而多个LED产 生的热量问题是不容忽视的。因此，为了提高LED路灯的使用寿命，需要解决LED基板的发 热问题。已有的直接散热式的LED路灯，是利用散热片将LED基板的热量传导到周围的空 气，这样的散热是缓慢地，效率不高。
实用新型内容
[0003] 针对上述问题，本实用新型提出一种直接利用散热通风系统来有效地解决LED基 板发热问题的LED路灯。
[0004] 本实用新型的技术方案是：
[0005] 本实用新型的带散热通风系统的LED路灯，包括连接于路灯基座上的路灯杆体及 连接于杆体上端的照明灯具。所述的照明灯具由所述的照明灯具由一灯罩、一导热硅胶层、 一 LED基板、一透光面板、复数个LED、一灯罩上壳及复数个风扇组成。其中，所述的灯罩是 内表面为凹陷型而外表面为复数个散热鳍片的金属外壳构件，所述的导热硅胶层设置于灯 罩和LED基板之间，将LED基板粘结固定于灯罩的内表面，所述的LED均勻设置于LED基板 上，所述的透光面板盖合于灯罩的开口，与之形成一个密闭的照明灯具的空间结构，所述的 灯罩上壳盖合于灯罩上方，所述的灯罩上壳内设有复数个风扇。
[0006] 进一步的，所述的灯罩外表面的散热鳍片是高低分布不一的结构。
[0007] 进一步的，所述的灯罩上设有复数个散热微孔。
[0008] 进一步的，所述的透光面板是水晶玻璃片。
[0009] 进一步的，所述的灯罩上壳上设有复数个散热通风孔。
[0010] 本实用新型采用如上技术方案，通过导热硅胶将LED基板的热量传递到带散热片 的一体的金属灯罩上，并通过灯罩上壳内的风扇，将金属灯罩上散热片的热量快速传递至 外界的空气中，可以高速有效地解决了 LED路灯散热问题，大大延长LED路灯的稳定使用寿 命。
附图说明
[0011] 图1是本实用新型的整体示意图。
3具体实施方式
[0012] 现结合附图和具体实施方式对本实用新型进一步说明。
[0013] 参阅图1所示，本实用新型的LED路灯，包括连接于路灯基座1上的路灯杆体2及 连接于杆体2上端的照明灯具3。所述的照明灯具3由所述的照明灯具3由一灯罩31、一 导热硅胶层32、一 LED基板33、一透光面板35、复数个LED 34、一灯罩上壳36及复数个风 扇37组成。其中，所述的灯罩31是内表面为凹陷型而外表面为复数个散热鳍片的金属外 壳构件，所述的导热硅胶层32设置于灯罩31和LED基板33之间，将LED基板33粘结固定 于灯罩31的内表面，所述的LED34均勻设置于LED基板33上，所述的透光面板35盖合于 灯罩31的开口，与之形成一个密闭的照明灯具的空间结构，所述的灯罩上壳36盖合于灯罩 31上方，所述的灯罩上壳36内设有复数个风扇37。
[0014] 优选的，所述的灯罩31外表面的散热鳍片是高低分布不一的结构。高低分布不一 的结构的散热鳍片更有利于热气体流动，加快空气流动，利于将灯罩31上的热量带走，利 于降温。
[0015] 优选的，所述的透光面板35是水晶玻璃片。这样，本实用新型的LED路灯透光率 更高，且透光面板35表面更不易被划伤，长期使用后透光率依然能保持稳定。
[0016] 本实用新型的LED路灯，是将LED基板33的热量通过导热硅胶层32传导到灯罩 31的散热鳍片311上，并辅助地通过散热微孔312加快散热。同时，通过灯罩上壳36内设 有复数个风扇37，将散热鳍片311上的热量通过散热通风孔361快速地传导到外界的空气 中。
[0017] 尽管结合优选实施方案具体展示和介绍了本实用新型，但所属领域的技术人员应 该明白，在不脱离所附权利要求书所限定的本实用新型的精神和范围内，在形式上和细节 上可以对本实用新型做出各种变化，均为本实用新型的保护范围。
