Description

LED路灯循环散热***
技术领域
本实用新型涉及一种LED路灯，特别涉及一种LED路灯循环散热***。
背景技术
随着现代文明的进步，城市道路照明发展迅速，各种大功率节能路灯竞相问世，高压钠灯曾一度以较白炽灯显著节能的优势，覆盖了新一轮路灯市场，近年来LED照明光源技术的性能指标得到突飞猛进的提高，这种固态光源其发光效率高，显色性能好，响应速度快，使用寿命长，与高压钠灯相比，LED比其节能60％以上，可以预见，未来的路灯节能改造必然将以LED为主导，LED作为新一代光源应用于灯具时，主要需要处理好散热和配光两大问题。
目前，市场上已经出现了大功率LED路灯产品，利用大功率LED光源取代传统路灯的光源，除了要解决配光问题外，散热问题是LED路灯产品需要解决的一个关键问题。一般的LED路灯为了解决散热问题，散热结构设计较复杂、耗材多、结构笨重，并且其散热效果也不尽理想。
发明内容
为了克服上述缺陷，本实用新型提供了一种LED路灯循环散热***，该路灯散热效率高，重量轻，且结构简单。
本实用新型为了解决其技术问题所采用的技术方案是：一种LED路灯循环散热***，所述LED路灯包括灯壳、支撑柱、热板、LED灯及电源，所述灯壳固定在支撑柱上，所述热板固定于支撑柱下方，所述LED灯固定于热板下方，所述灯壳由蒸发板和若干蒸发管组成，若干蒸发管设于蒸发板外表面且蒸发管之间相互连通；所设灯壳内还设有一上升管，上升管一端与热板的一端密封连通,所述上升管另一端与蒸发板顶端的蒸发管密封连通；所述热板呈中空状，热板的另一端通过两根下降管与灯壳两侧的蒸发管密封连通，所述蒸发管、下降管、上升管和热板之间构成一封闭的散热循环回路，且散热循环回路中充有冷却介质，当开启LED灯后，冷却介质在热板中加热蒸发由上升管进入灯壳顶端，在灯壳外表面经过蒸发管冷却后由下降管重新进入热板，形成循环散热。
作为本实用新型的进一步改进，所述蒸发管呈蛇形排列均匀分布于蒸发板外表面，蒸发管的蛇形分布有效增加了介质散热的效果，使介质冷却更充分。
本实用新型的有益效果是：该LED路灯将灯壳与内部结构中的灯板、上升管和下降管之间构成一散热循环回路，并在循环回路中充入冷却介质，有效的解决了LED路灯照明的散热问题，从而提高了路灯的使用寿命，同时该路灯散热效率高，重量轻，且结构简单。
附图说明
图1为本实用新型结构示意图。
具体实施方式
实施例：一种LED路灯循环散热***，所述LED路灯包括灯壳1、支撑柱2、热板3、LED灯4及电源5，所述灯壳1固定在支撑柱2上，所述热板3固定于支撑柱2下方，所述LED灯固定于热板3下方，所述灯壳1由蒸发板11和若干蒸发管12组成，若干蒸发管12设于蒸发板11外表面且蒸发管之间相互连通；所设灯壳1内还设有一上升管7，上升管7一端与热板3的一端密封连通,所述上升管7另一端与蒸发板11顶端的蒸发管12密封连通；所述热板3呈中空状，热板3的另一端通过两根下降管6与灯壳1两侧的蒸发管12密封连通，所述蒸发管12、下降管6、上升管7和热板3之间构成一封闭的散热循环回路，且散热循环回路中充有冷却介质，当开启LED灯后，冷却介质在热板3中加热蒸发由上升管7进入灯壳1顶端，在灯壳1外表面经过蒸发管12冷却后由下降管6重新进入热板3，形成循环散热。
所述蒸发管12呈蛇形排列均匀分布于蒸发板11外表面。蒸发管12的蛇形分布有效增加了介质散热的效果，使介质冷却更充分。
