Description

一种LED线路板、LED模组及照明灯具 技术领域
本发明涉及照明技术领域，尤其涉及一种LED线路板、LED模组及照明灯具。
背景技术
LED(light emitting diode，发光二极管)灯具中有非隔离电源和隔离电源之分。非隔离电源中，负载端和输入端直接连接，触摸负载有触电的危险，隔离电源中负载端和输入端设置变压器把负载端和输入端隔离开，触摸负载没有触电危险。但是隔离电源的灯具由于要设置变压器，成本和安装空间都受限制。随着灯具成本的竞争日益激烈化，更高性价比的非隔离电源的灯具越来越多的被使用。然而由于非隔离电源的结构，其输出端都是带电的部位，人不能直接接触否则有触电风险。所有的非隔离电源的LED模组必须要增加额外的保护结构不能让任何带电部位裸露在外。而LED线路板中的白油层本身达不到隔离非隔离电源的安规的要求，且白油层容易受到尖锐物品的刮蹭把导电铜箔露出来，因此无法起到绝缘的作用。如果要增加额外的防触电保护措施，不但增加整体的成本，更使组装变得更加复杂。
