一种均热板散热的集成式LED路灯
技术领域
本发明涉及一种均热板散热的集成式LED路灯，具体是涉及一种均热板散热的集成式LED路灯。
背景技术
由于LED灯的节能，长寿命和易维护等特点，近几年人们对led技术的关注，LED照明技术得到了不断的发展，但是对于大功率led灯而言，至为关键的问题之一是LED照明的散热问题，LED散热的好坏对于整灯而言至关重要，如果热量不能散出去，会加速芯片的老化、光衰、色偏移、缩短LED的寿命，降低灯具光效等，换言之散热问题决定了灯具的寿命长短，严重制约着LED照明的发展。温度对LED本身的寿命也有影响，温度越高寿命越短。解决LED的散热就是要降低LED本身的结温。散热器是用来传导、释放热量的一种装置。根据散热的对象不同，采用的散热方式也不相同，有的采用散热片进行自然冷却的方式，有的采用安装风扇进行风冷的方式。现在LED路灯光源散热片所选的结构，在一大铝板块背上，竖着很多散热片状结构，是一种自然对流散热性能最差的结构，造成LED芯片的防水防湿的结构复杂，又不适合电源散热和防雨水，加重了整个路灯重量，提高了成本造价，是导致目前LED路灯较为严重的问题。因此，更好的实现灯具的散热将是目前所面对的技术挑战之一。
发明内容
本发明提供一种均热板散热的集成式LED路灯，其能有效的散出热量，又能降低整灯重量。
本发明主要包括集成LED光源、圆形卡座、壳体、紧固螺钉、架体、连接线、灯杆卡座、驱动电源、散热器、二次光学透镜以及均温板。
所述集成式LED光源由集成式LED芯片和封装体组成，集成LED光源的背部安装在均温板上，均温板居中安装在散热器上，散热器采用鳍片式散热器。
所述集成式LED光源上安设二次光学透镜，二次光学透镜优选配光曲线为蝙蝠翼型，LED光源和二次光学透镜由圆形卡座固定。
所述壳体上表面采用弧形设计，且上设多组条形空隙，整灯壳体通过紧固螺钉固定在架体上。
所述驱动电源安装在灯杆卡座内，驱动电源通过连接线与集成LED光源连接。
采用上述技术方案，利用均热板和散热器散去集成式LED芯片产生的大量的热。壳体表面空隙设计也可形成对流，带走部分热量。将驱动电源安置在灯杆卡座内，避免安置在灯壳内部时与LED芯片的热量聚集，可以更有效的利用散热装置为集成式LED芯片散热。该方案散热效果好、速度快，可有效避免LED结温升高，同时减小灯壳的体积、降低散热片用量，减轻整灯重量。
附图说明
图1为一种均热板散热的集成式LED路灯示意图。
图2为LED灯壳体侧剖图。
具体实施方式
如图1和图2所示，本发明一种均热板散热的集成式LED路灯，由集成LED光源1、圆形卡座2、壳体3、紧固螺钉4、架体5、连接线6、灯杆卡座7、驱动电源8、散热器9、二次光学透镜10以及均温板11组成；所述集成式LED光源1由集成式LED芯片101和封装体组成，集成式LED光源1的背部安装在均温板11上，均温板具有传热速度快、均温性能良好的特点，可实现快速导热，均温板11居中安装在散热器9上，散热器采用鳍片901式散热器；所述集成式LED光源1上安设二次光学透镜10，二次光学透镜优选配光曲线为蝙蝠翼型，具有良好的照明效果，可满足道路照明的需求，LED光源和二次光学透镜由圆形卡座固定，将LED芯片101密封在内；所述壳体3上表面采用弧形设计，且上设多组条形空隙301，如此可形成空气对流，加快热量的散失。壳体3通过紧固螺钉4固定在架体5上，架体采用花式架体结构，既能有效固定支撑灯体，又可节省材料；所述驱动电源8安装在灯杆卡座7内，驱动电源通过连接线6与集成LED光源1连接，连接线裸露在外部分应具有防水等性能，且紧贴架体固定。驱动电源产生的热量可在灯杆卡座内散去，不会与集成LED芯片产生的热量聚集。
本发明主要利用均温板进行导、散热，并将驱动电源安装在原来LED芯片的灯杆卡座内，避免聚热，采用花式框体架构可有效减轻整灯重量，如此既能有效散热，体积小、重量轻的整灯必将在均热板散热的集成式LED路灯中有很大前景。
