Research: This LED can reduce the negative impact of light on plants and animals


In the new era of lighting, with the increase of people-oriented awareness, human lighting has emerged. The concept of circadian rhythm adjusts the light and enhances the spirit of the person at a specific time. This concept of changing the light illumination darkness as a person's daily routine is human illumination. Human lighting solves the impact of light on the human body and is used to develop innovative lighting technologies to reduce the negative effects of artificial light sources and thus improve people’s quality of life. In addition to the human body, scientists also studied the effects of artificial light on wildlife. Scientists have conducted a study to study the ecological effects of various light sources through different spectra, and have developed a method that can reduce the negative effects of artificial light on wildlife.

The development of LED technology provides a broader spectrum of light, providing more choices for lighting applications. Travis Longcore, a University of Southern California urban ecologist, based on his understanding of different spectra, led his team to measure 26 LED lighting products to predict the effect of different spectral lines. Instead of directly testing animals.

The team collected published data and estimated the likely response of light-sensitive organisms such as sea turtles, insects and fish to a range of lamp types and light sources. Based on the calculated data, the team developed an indicator to identify different luminaires and predict their impact based on ecology, physiology, and astronomy indices.

The results of the study indicate that filtered yellow-green LEDs and amber LEDs may have a smaller effect on animals compared to high-pressure sodium lamps. On the contrary, more blue light sources will have a greater adverse effect on them.

It is reported that the purpose of this study is to establish a database for lighting designers and groups responsible for installing public lighting systems. Based on the information provided by the study, they were able to choose different options that used new lighting technologies and had fewer negative impacts on wildlife.
