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

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.
