Recently, news about “LED lighting can damage the retina, potentially causing blindness” has sparked heated discussions online, leading some individuals to hesitate in using LED courtyard lights. Many people are confused—do LED courtyard lights really harm our eyes?
In response to the above questions, the editor of professional courtyard lamp street lighting provides the following answers:
This is akin to asking whether sunlight hurts the eyes. LED courtyard lights, as representatives of low-carbon and environmentally friendly lighting tools in the new era, have advantages such as low consumption, low heat, long usage time, and being environmentally friendly. Given the many benefits of LED lighting, why is there a lack of trust?
Ultimately, one significant factor is that blue light can harm the eyes! The white paper “General Lighting LED and Blue Light” mentions that light with wavelengths between 400 and 500 nm is referred to as the blue light zone. Prolonged exposure to blue light can easily cause eye damage, especially leading to macular degeneration. Engineers have summarized through a series of data that normal LED lamps and those equipped with diffusers have blue light levels within a normal range and will not harm the retina. However, LED lights without diffusers and with a power exceeding 1 watt can significantly damage the eyes, whether operating at full or half power.
Experts remind us that the household LED courtyard lights available on the market are generally harmless when used correctly. It is essential to avoid looking directly at LED courtyard lights, not to remove the diffuser, and to replace any damaged diffusers promptly to prevent light leakage.
In fact, blue light is not only present in LED courtyard lights; devices such as smartphones and computer screens also emit blue light. To protect your eyes, avoid staring at these screens for extended periods or consider using lenses that can block blue light.
With the advent of new technologies, there always comes skepticism. Today, LED courtyard lights are in the process of replacing traditional lighting systems, and there is still a long way to go for future innovations in the lighting industry.
