Project Description

In recent years, there has been a significant increase in the number of products incorporating light-emitting diode (LED) technology. Their increased use has elevated concerns about potentially harmful photobiological effects that can result from even incidental exposure to LED light.

In response to these concerns, today’s product safety standards now include specific testing requirements to evaluate and classify the photobiological risks associated with many types of LEDs. This UL white paper presents an overview of the structure and requirements of current photobiological standards for LEDs. Beginning with background information on the growth in the use of LEDs, the paper discusses the photobiological hazards associated with exposure to LEDs and other types of lamps. The paper then offers a detailed review of the current photobiological safety standards, IEC 62471 and IEC/TR 62471-2, including summary information on testing, exposure limits, and risk groups.

The paper concludes with a look at potential future standards development efforts in this area, and compliance considerations for LED manufacturers.
