Description

一种LED户外显示模组
[技术领域]
本实用新型涉及LED显示领域，具体指一种LED户外显示模组。 
[背景技术]
通常，现有LED户外模组中贴片LED按象素点分布在PCB板上，为保护PCB板，采用电子灌封胶灌注在贴片LED与PCB板之间。如果电子灌封胶覆盖不住贴片LED，要求贴片LED本身防水，LED户外模组防水功能不佳，同时灌胶工艺比较复杂，成本较高。 
[实用新型内容]
本实用新型目的在于解决上述的问题，而提供一种成本低、防水功能良好、性能可靠的LED户外显示模组。 
本实用新型LED户外显示模组，包括PCB组装件、安装所述PCB组装件的模组后壳，所述PCB组装件包括PCB板和设于所述PCB板表面的贴片LED阵列，所述PCB组装件的表面覆盖有一层乙烯一四氟乙烯透明罩，所述透明罩外表面还设有模组面罩，透明罩上还具有容纳贴片LED的凸块。 
优选的，所述模组面罩设有多条平行的遮光沿，LED位于相邻遮光沿之间。 
进一步的，所述模组面罩还设有多条平行的吸光沿，所述吸光沿位于所述遮光沿与贴片LED之间，所述吸光沿比所述遮光沿矮。 
所述透明罩的厚度小于0.2mm。 
本实用新型中所述透明罩将贴片LED阵列和PCB板覆盖住，防尘防水，而且所述透明罩一次成型，安装方便，成本低。所述模组面罩增加LED户外模组显示的对比度。 
[附图说明] 
图1是本实用新型实施例提供的LED户外显示模组的结构示意图； 
图2是本实用新型实施例提供的LED户外显示模组的横截面示意图。 
[具体实施方式]
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解此处所描述的具体实施实例仅仅用以解释本实用新型，并不用于限定本实用新型。 
本实用新型实施例提供的LED户外模组采用整体成型的乙烯一四氟乙烯透明罩覆盖住贴片LED阵列和PCB板，防尘防水，安装方便，成本低。 
一种LED户外模组，包括：PCB组装件和安装所述PCB组装件的模组后壳，所述PCB组装件包括PCB板和设于所述PCB板表面的贴片LED阵列，所述PCB组装件的表面覆盖有一层乙烯一四氟乙烯透明罩。 
如图1和图2所示，本实用新型实施例提供的LED户外模组具有一块PCB板4，所述PCB板4表面设有贴片LED阵列，所述PCB板4和所述贴片LED阵列组成PCB组装件，所述PCB组装件安装在模组后壳5。所述PCB组装件表面覆盖有一层透明罩6。所述透明罩6由乙烯一四氟乙烯(ETFE)薄膜整体一次热压成型，厚度较薄，能成型为小于0.2mm的厚度；所述贴片LED7发出的热量经由所述透明罩6传导至外界，模组散热效果好。此外，乙烯一四氟乙烯(ETFE)制成的透明罩6透光率达95％以上，还易于清洗。所述透明罩6热压成型后，具有容纳贴片LED的凸块8。所述透明罩6外表面还设有模组面罩9，所述模组面罩9设有若干条平行的遮光沿10，贴片LED位于相邻遮光沿之间，所述遮光沿10具有遮光作用，增加LED户外模组显示的对比度。另外，所述模组面罩还设有多条平行的吸光沿11，所述吸光沿11位于所述遮光沿10与贴片LED7之间，所述吸光沿II比所述遮光沿10矮，增强了对比效果。 
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
