Description

一种高效散热LED路灯
技术领域
本发明属于LED路灯设备技术领域，具体涉及一种高效散热LED路灯。
背景技术
众所周知，LED名为发光二极管，属于一种半导体固体发光器件，LED照明就是利用LED作为光源制造出来的照明器具，适用于各种需要光源的场合，目前市场上的LED路灯由于功率大，照明强，所以导致发热量也大，如果不能及时有效散热的话，堆积在LED光源周威的热量将致使光源快速衰减，能耗增加，直接影响LED路灯的使用周期，增加了成本。
发明内容
本发明旨在解决上述缺陷，提供了一种高效散热LED路灯。
为了克服背景技术中存在的缺陷，本发明解决其技术问题所采用的技术方案是：一种高效散热LED路灯，包括透光罩、LED发光源、PCB板、散热片和冷板，所述透光罩与散热片密封连接，所述LED发光源安装于PCB板上，所述PCB板与散热片粘贴连接，所述散热片两两之间的凹槽处设有冷板，所述冷板上设有冷却管路，所述冷却管路中填充有冷却液。
在本发明的一个较佳实施例中，所述冷板与散热片可拆卸连接。这样有利于更方便的对冷板进行维护和保养，使得冷板保持较好的散热性能。
本发明的有益效果是：结构简单，节能高效，安装的散热片本身就能起到很好的散热效果，在散热片的凹槽处设有冷板，冷板上设有冷却管路，冷却管路中填充有冷却液，从而加速了散热片的散热性能，进一步提高了LED路灯的散热效果，保证了LED路灯的使用周期和稳定性。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图。
图中1为透光罩、2为LED发光源、3为PCB板、4为散热片、5为冷板、6为冷却管路。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
如图1所示，一种高效散热LED路灯，包括透光罩1、LED发光源2、PCB板3、散热片4和冷板5，所述透光罩1与散热片4密封连接，所述LED发光源2安装于PCB板3上，所述PCB板3与散热片4粘贴连接，所述散热片两4两之间的凹槽处设有冷板5，所述冷板5上设有冷却管路6，所述冷却管路6中填充有冷却液。
在本发明的一个较佳实施例中，所述冷板5与散热片4可拆卸连接。这样有利于更方便的对冷板进行维护和保养，使得冷板保持较好的散热性能。
本发明的有益效果是：结构简单，节能高效，安装的散热片本身就能起到很好的散热效果，在散热片的凹槽处设有冷板，冷板上设有冷却管路，冷却管路中填充有冷却液，从而加速了散热片的散热性能，进一步提高了LED路灯的散热效果，保证了LED路灯的使用周期和稳定性。
