Measuring the Photobiological Safety of LED Lighting

Introduction

What is Photobiological Safety?

Photobiological safety is the assessment of the potential for a light source to cause harm to the human eye or skin. It is an important consideration when designing LED lighting systems, as LED lighting can emit light in the ultraviolet (UV) and visible light spectrum. The International Electrotechnical Commission (IEC) has established standards for measuring the photobiological safety of LED lighting, which are used to ensure that LED lighting systems are safe for human use.

How is Photobiological Safety Measured?

The IEC has established two methods for measuring the photobiological safety of LED lighting. The first is the Maximum Permissible Exposure (MPE) method, which measures the amount of light that can be safely exposed to the human eye. The second is the Maximum Permissible Irradiance (MPI) method, which measures the amount of light that can be safely exposed to the human skin.

Testing LED Driver or Mobile or Automotive Electronics

When testing LED driver, mobile, or automotive electronics, it is important to ensure that the photobiological safety of the LED lighting system is not compromised. To do this, the IEC standards for measuring the photobiological safety of LED lighting must be followed. This includes testing the LED driver, mobile, or automotive electronics for compliance with the MPE and MPI standards. Additionally, the LED lighting system must be tested for compliance with the IEC standards for optical radiation, which includes testing for UV and visible light emissions.
