IEC 62471-5-2015 灯和灯系统的光生物学安全--第5部分:图像投影仪 Photobiological safety of lamps and lamp systems - Part 5: Image projectors

This part of IEC 62471 provides requirements regarding photobiological safety of the optical
radiation emitted by image projectors. This part of IEC 62471 does not deal with other
hazards such as electrical, mechanical or fire hazards.
This part of IEC 62471 provides requirements regarding: 
• optical radiation safety assessment of image projectors;
• projector risk groups; 
• testing conditions and measurement conditions; 
• manufacturer’s requirements including user information. 
The scope of this part of IEC 62471 is photobiological safety of image projectors including the
emissions from laser-illuminated projectors that fulfill the requirements as specified in
IEC 60825-1:2014, 4.4 and for which visible light emission has been excluded from
classification in IEC 60825-1.  
This part of IEC 62471 does not address safety requirements for laser display products where
collimated laser beams — generally scanned — are employed. It does address those laser-
illuminated projectors that employ a laser source to illuminate, for example, a micro-electro-
mechanical system (MEMS) without scanned beams or crystal-based display projector system. 
NOTE Image projectors containing lasers are subject to those provisions of IEC 60825-1 applicable to the embedded laser. See IEC 60825-1:2014, 4.4 for which visible light emission has been excluded from the laser product classification.
This part of IEC 62471 includes projectors for only visible image projection and does not
include ultraviolet (UV) projectors, infrared (IR) projectors, general lighting service (GLS)
lamps (GLS; defined in IEC 62471) or projector lamp systems used for general lighting, which
are treated in separate International Standards.dition 1.0 2015-06 INTERNATIONAL STANDARD colour inside Photobiological safety of lamps and lamp systems – Part 5: Image projectors IEC 62471-5:2015-06(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2015 IEC, Geneva, Switzerland All rights reserved.
