Introduction
Investigating Photobiological Effects of LED Lighting
Light-emitting diodes (LEDs) are becoming increasingly popular in a variety of applications, from lighting to automotive electronics. LEDs are known to emit light in the visible spectrum, but they also emit light in the ultraviolet (UV) and infrared (IR) spectrums. This raises the question of whether or not LED lighting can have photobiological effects on humans and other living organisms. In this article, we will explore the potential photobiological effects of LED lighting and discuss how to test LED drivers and mobile or automotive electronics for these effects.
What are Photobiological Effects?
Photobiological effects are the biological effects of light on living organisms. These effects can range from beneficial to harmful, depending on the type of light and the intensity of the light. For example, exposure to UV light can cause sunburns and skin cancer, while exposure to blue light can help regulate the body’s circadian rhythm.
LEDs emit light in the visible spectrum, as well as in the UV and IR spectrums. This means that LEDs can potentially have photobiological effects on humans and other living organisms.
Testing for Photobiological Effects
In order to test for photobiological effects, it is important to measure the intensity of the light emitted by the LED. This can be done using a spectrometer, which measures the intensity of light at different wavelengths. It is also important to measure the amount of UV and IR light emitted by the LED, as these can have photobiological effects.
Once the intensity of the light emitted by the LED has been measured, it is important to test the LED driver or mobile or automotive electronics for any potential photobiological effects. This can be done by exposing test subjects to the LED light and measuring any changes in their physiology or behavior.
