BS EN 62471-5:2015,即《光生物安全性标准:灯具和照明系统——第五部分:投影仪》是由英国标准化机构BSI发布的一项重要标准。该标准旨在确保灯具和投影仪等光学辐射设备在设计、制造和使用过程中符合国际光生物学安全规范,其目标是防止因光辐射对人眼和皮肤造成潜在的伤害,如视网膜损伤和皮肤癌风险。 该标准是英国对欧洲标准EN 62471-5:2015的本土化实施,与国际电工委员会(IEC)的IEC 62471-5:2015保持一致。其制定过程由英国电气、电子和光子技术委员会EPL/76负责,该委员会集合了来自多个组织的专业专家,用户可以通过向该委员会秘书索取资料获取委员会成员列表。 本标准并不涵盖所有合同所需的详细规定,使用者需自行确保正确应用。版权归属英国标准机构,于2015年10月31日经标准政策和策略委员会授权发布。在出版后,如有必要,可能会发布修正案或更正,这些信息可以在标准的后续更新中查到。 该标准适用于分类号为29.140的领域,意味着它主要关注的是与光辐射相关的安全标准,但遵循标准并不能免除用户在法律上的责任。此外,标准提供了英文版,表明其具有广泛的国际适用性,不仅限于英国,而是针对整个欧洲市场。 通过BS EN 62471-5:2015,制造商和设备使用者必须了解和遵守其中关于投影仪光谱特性、亮度、眩光控制、闪烁限制以及对眼睛和皮肤安全性的评估方法。理解并实施这些要求对于保证公众在使用投影仪时的安全至关重要,无论是学校、办公室还是娱乐场所,都需要确保所使用的投影设备符合这一国际标准。

INTRODUCTION
Most lamps and lamp systems are safe and do not pose photobiological risks except under
unusual exposure conditions. This also is the case for optical image projectors where
experience shows that even high power cinema projectors may be safe for accidental
momentary viewing and can only under some conditions pose optical hazards at close
distances or for intentional 'long-duration' staring into the source. The rapid development of
solid-state and other lamps or lamp systems has permitted new projector products, and
generated the need for a photobiological safety standard for this group of lamp systems.
Optical radiation hazards from all types of lamps and lamp systems are currently assessed by
the application of IEC 62471:2006 (CIE S 009:2002), Photobiological safety of lamps and
lamp systems. IEC 62471 covers LEDs, incandescent, low- and high-pressure gas-discharge,
arc and other lamps. Following the concept of vertical standards, the risk group classification
system in IEC 62471 for lamps is to be adapted for specific product groups such as image
projectors.
This part of IEC 62471 provides a risk group classification system for image projectors, and
measurement conditions for optical radiation emitted by image projectors. It includes
manufacturing requirements that may be required as a result of an image projector system
being assigned to a particular risk group. Therefore, this part of IEC 62471 provides safety
requirements for lamp systems that are intended to produce projected visible optical radiation,
such as theatre projectors, data projectors and home-use projectors. The assigned risk group
of a projector product also may be used by projector manufacturers to assist with any risk
assessments, e.g. for occupational exposure in workplaces. National requirements may exist
for the assessment of products or occupational exposure.
The emission limits provided in this part of IEC 62471 are derived from the exposure limits
specified by ICNIRP in their 2013 Guidelines for incoherent visible and infrared radiation [1]

.
These exposure limits are also the basis for the emission limits to be specified in the future
International Standard IEC 62471-1

PHOTOBIOLOGICAL SAFETY OF LAMPS AND LAMP SYSTEMS –
Part 5: Image projectors
1 Scope
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.
