Description

防水散热的LED显示屏灯箱
技术领域
本实用新型涉一种显示屏灯箱，具体是涉及一种有良好散热以及防水作用的LED显示屏灯箱。
背景技术
随着科技的发展，LED 显示屏被广泛的运用在生活和生产中，但LED功率的不断加大，使LED显示屏散热成为一项艰巨的任务，LED的光衰或其寿命是直接和其结温有关，散热不好结温就高，寿命就短。所以解决LED散热问题成为当今提高LED性能，发展LED产业的主要问题。另外，LED显示屏较多用于户外，在户外，风吹日晒雨淋不可避免，所以LED显示屏的防水设计也面临挑战。中国专利CN 203480785公开了一种防水散热LED显示屏模组，该显示屏能达到防水散热的效果，但是其小型通孔的设计使防水方面不能达到较好的效果，因此在更好的防水方面需要改进。
实用新型内容
针对现有技术中的不足，本实用新型提供一种防水散热的LED显示屏灯箱
为了解决上述技术问题，本实用新型的技术方案如下：
防水散热的LED显示屏灯箱，包括箱体外壳、电路板、LED灯，其特征在于，所述箱体外壳正面没有LED灯的地方涂有防水材料，所述LED灯与所述电路板之间设有绝缘隔热层，所述箱体后部设有吸热层和散热层，所述电路板与吸热层之间呈空腔结构，所述箱体背面设有散热翅片，翅片尾部与水平线夹角为60°并向下倾斜。
所述散热层为呈百叶窗结构的铝散热片。
本实用新型的有益效果在于：本实用新型能够起到良好的散热效果，并且有效起到防水的作用，保证雨水不会流进LED显示屏灯箱内部。
附图说明
下面结合附图以及实施例对本实用新型做进一步的说明。
图1为本实用新型的结构示意图。
具体实施方式
本实用新型提供的防水散热的LED显示屏灯箱，在现有LED显示屏灯箱的基础上进一步改进，保证在LED显示屏正常使用的情况下，起到良好的防水、散热的效果。具体结构参见图1。
灯箱1的正面（即亮灯面）设有若干个LED灯3，LED灯3安装在电路板2上，且LED灯3与电路板2之间设有绝缘隔热层5，在灯箱1的正面，没有LED灯的位置涂有防水材料4，这保证雨水不会通过LED灯的缝隙进入箱体内。
灯箱1的后部分设有吸热层6和散热层7，吸热层6与电路板2之间呈空腔结构。在灯箱1的背面（即亮灯面的对立面）设置成为翅片的结构，散热翅片8使雨水不会进入箱体。散热翅片8的翅片向下倾斜，且与水平线之间的角度为60°。
为了达到更好的散热效果，优选地，散热层7设为呈百叶窗结构的铝散热片。
整个LED显示屏灯箱结构起到了良好的散热的效果，并且在现有技术的基础上能增加其防水的效果，有效延长了LED显示屏的使用寿命。
以上所述仅是本发明创造的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明创造所述原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明创造的保护范围。
