Measuring Photobiological Risks of LED Lighting

Introduction

What is Photobiological Risk?

Photobiological risk is the potential for harm to humans or other living organisms from exposure to light. This risk is associated with the amount of light, the wavelength of the light, and the duration of exposure. LED lighting is becoming increasingly popular due to its energy efficiency and long life. However, LED lighting can also pose a photobiological risk if not properly designed and tested.

Measuring Photobiological Risk of LED Lighting

Measuring photobiological risk of LED lighting involves testing the light source to ensure it meets safety standards. This testing includes measuring the amount of light emitted, the wavelength of the light, and the duration of exposure. Testing can be done on LED drivers, mobile devices, and automotive electronics.

Testing LED Drivers

Testing LED drivers involves measuring the amount of light emitted, the wavelength of the light, and the duration of exposure. The amount of light emitted is measured in lumens, which is a measure of the total amount of visible light emitted by a source. The wavelength of the light is measured in nanometers (nm), which is a measure of the color of the light. The duration of exposure is measured in seconds, which is a measure of how long the light is exposed to a person or other living organism.

Testing Mobile Devices

Testing mobile devices involves measuring the amount of light emitted, the wavelength of the light, and the duration of exposure. The amount of light emitted is measured in lux, which is a measure of the amount of light emitted per square meter. The wavelength of the light is measured in nanometers (nm), which is a measure of the color of the light. The duration of exposure is measured in seconds, which is a measure of how long the light is exposed to a person or other living organism.

Testing Automotive Electronics

Testing automotive electronics involves measuring the amount of light emitted, the wavelength of the light, and the duration of exposure. The amount of light emitted is measured in candelas, which is a measure of the amount of light emitted per square meter. The wavelength of the light is measured in nanometers (nm), which is a measure of the color of the light. The duration of exposure is measured in seconds, which is a measure of how long the light is exposed to a person or other living organism.

Conclusion

Measuring photobiological risk of LED lighting is an important step in ensuring the safety of people and other living organisms. Testing LED drivers, mobile devices, and automotive electronics can help ensure that the light sources meet safety standards. By measuring the amount of light emitted, the wavelength of the light, and the duration of exposure, manufacturers can ensure that their products are safe for use.
