As a result, growing importance of potential safety harzards for human. Now when certificated of CE provide that testing through IEC/EN 62471 for any lamp. Korea standard adopted as it IEC 62471:2006, Photobiological safety of lamps and lamp systems without change, but effectiveness is incomplete. In this paper, we introduce analysis and direction that urgently come into effectiveness of KS C IEC 62471 as a national standard specifications.
