Description

一种具有杀菌功能的灯具 技术领域
本申请涉及灯具，尤其涉及一种具有杀菌功能的灯具。
 背景技术
UVC-LED作为热门的新型深紫外光源，其释放的波长200-280nm的深紫外线能直接破坏细菌和病毒的DNA或RNA，起到快速、安全无副作用的杀菌效果，但同时会破坏辐射范围内的氧气空气与植物及水果饭菜成分。紫外线消毒是利用适当波长的紫外线能够破坏微生物机体细胞中的DNA（脱氧核糖核酸）或RNA（核糖核酸）的分子结构，造成生长性细胞死亡和（或）再生性细胞死亡，达到杀菌消毒的效果。紫外线消毒技术是基于现代防疫学、医学和光动力学的基础上，利用特殊设计的高效率、高强度和长寿命的UVC波段紫外光照射流水，将水中各种细菌、病毒、寄生虫、水藻以及其他病原体直接杀死，达到消毒的目的。
现有的UVC（ultraviolet C，使用短波紫外线）杀菌灯，其在杀毒过程中对人体产生辐射，尤其对眼睛、皮肤等部位的侵害很大。使用者在开关灯过程会被辐射侵害人类健康，导致辐射范围内的食品和植物等变质营养成分破坏丢失。UVC-LED作为热门的新型深紫外光源，其释放的波长200~280nm的深紫外线能直接破坏细菌和病毒的DNA或RNA，起到快速、安全无副作用的杀菌效果、但同时会破坏辐射范围内的氧气空气与植物及水果饭菜成分。
