Description

发光二极管照明装置
技术领域
本发明涉及一种发光二极管照明装置。
背景技术
发光二极管是一种节能、环保、长寿命的固体光源，因此近十几年来对发光二极管技术的研究一直非常活跃，发光二极管也有渐渐取代日光灯、白炽灯等传统光源的趋势。在现有技术中，发光二极管照明装置一般只能朝向一个方向发光，而无法实现多角度发光，在一些特定场合，不能够满足实际需要。
发明内容
有鉴于此，有必要提供一种可实现多角度发光的发光二极管照明装置。
一种发光二极管照明装置，其包括发光部以及承载座。所述发光部包括透光基板、分别设置在该透光基板两端的第一电极以及设置在该透光基板上并与第一电极电连接的发光二极管。所述承载座承载所述发光部，所述承载座由透光材料构成，其上设有与所述第一电极电连接的第二电极。
上述的发光二极管照明装置中，发光二极管发出的光线可从发光二极管照明装置的正面射出，并且还可以穿过透光基板以及承载座从背面和侧面射出，从而实现了多角度发光。

具体实施方式
下面将结合附图，对本发明作进一步的详细说明。
请参阅图1以及图2，本发明实施方式提供的一种发光二极管照明装置100包括一发光部10以及承载该发光部10的一承载座20。
所述发光部10包括一透光基板11、设置在该透光基板11上的若干间隔设置的发光二极管12、分别设置在该透光基板11相对两端的第一电极13以及覆盖发光二极管12的第一荧光层14。
请接着参阅图3，所述透光基板11为纵长板状结构，其由玻璃、塑胶等透光材料构成。所述发光二极管12呈直线排列设置在透光基板11的远离承载座20的上表面上，各发光二极管12之间相互串联，并且两端的发光二极管12分别与第一电极13电连接。
所述第一电极13分别设置在透光基板11的相对两端，其包括一方形的固定部131、由该固定部131的底部延伸形成的第一连接部132以及由该固定部131的顶部延伸形成的第二连接部133。该固定部131固定在透光基板11的上表面。该第一连接部132及第二连接部133的延伸方向相反，且其末端均超出固定部的边缘并分别位于固定部的相对两侧。具体的，该第一连接部132贴附在所述透光基板11上表面并朝向发光二极管12水平延伸，用于与发光二极管12电连接。该第二连接部133朝向远离发光二极管12方向水平延伸，用于与所述承载座20电连接。所述固定部131的外侧面与所述透光基板11的两端的端面齐平。
所述第一荧光层14覆盖所述发光二极管12以及透光基板11表面，其为一透明结构，材质可为硅、玻璃、环氧树脂等。荧光粉材质可选自石榴石、硅酸盐、氮化物、氮氧化物、磷化物、硫化物中之一或几种组合的化合物。
请接着参阅图4以及图5，所述承载座20为透光材料构成，其包括一纵长板状结构的透光底壁21以及由该透光底壁21的四个侧边垂直向上延伸的透光侧壁22。该透光底壁21和该透光侧壁22共同围成一凹槽23，该凹槽23的大小与所述发光部10的透光基板11的大小大致相当，其用于***述透光基板11。该凹槽23的内表面涂覆有第二荧光层24。
所述承载座20与所述透光基板11上的第一电极13相对应的两透光侧壁22上分别设置有第二电极25。该第二电极25包括设置在透光侧壁22顶部的水平延伸部251以及由该水平延伸部251沿透光侧壁22外表面垂直向下延伸的垂直延伸部252。该第二电极25的水平延伸部251用于与第一电极13电连接，垂直延伸部252用于与外部电源电连接。
在组装时，首先将发光部10的透光基板11收容于承载座20的凹槽23中，此时，第一电极13的第二连接部133覆盖在第二电极25的水平延伸部251上，然后焊接第一电极13的第二连接部133与第二电极25的水平延伸部251，从而将发光部10固定于承载座20中。
在使用时，发光二极管12发出的光线可从发光二极管照明装置100的正面射出，并且发光二极管12发出的光线还可以穿过透光基板11以及承载座20的透光底壁21从背面射出，也可以穿过透光基板11以及承载座20的透光侧壁22从侧面射出，从而实现了多角度发光。另外，发光二极管12正向发出的光线主要激发第一荧光层14，而背向以及侧向发出的光线主要激发涂覆在凹槽23的内表面的第二荧光层24，因此通过选择不同的荧光粉材料，可以实现发光二极管照明装置100正向光线与背向以及侧向光线的颜色不同，可以满足不同的实际需要。
可以理解的是，对于本领域的普通技术人员来说，可以根据本发明的技术构思做出其它各种像应的改变与变形，而所有这些改变与变形都应属于本发明权利要求的保护范围。
