Basic Information of the Visible Light Wavelength Chart
Have you ever had clients requesting amber, red, blue, or other specific color LED chips? Do you know why they need those particular wavelengths?
Today, we’ll dive into some essential insights about visible light wavelength charts and their importance in the lighting industry.
What Is Visible Light?
Visible light is a form of electromagnetic radiation that stimulates human and animal vision. It is the portion of the electromagnetic spectrum that the human eye can perceive, typically ranging from 380 to 750 nanometers (nm). This range is also referred to as the visible light spectrum.
Although artificial light sources are mostly electric, the light they emit is a non-electrical phenomenon and is measured using photometric quantities and scientific laws.
Animals may perceive different parts of the electromagnetic spectrum, but the human eye is limited to a narrow band—the visible spectrum. Each wavelength within this band corresponds to a different color:
Visible Light Wavelength Chart
Red: 625–750 nm
Orange: 565–625 nm
Yellow: 500–565 nm
Green: 485–500 nm
Blue: 450–485 nm
Violet: 380–450 nm
Human vision is most sensitive to the middle of the spectrum (green-yellow), and less effective at either end.
Why Understanding the Visible Light Wavelength Chart Matters
Understanding the visible light wavelength chart not only helps lighting professionals explain color choices to clients, but also supports project customization. Different light colors have various effects on humans, animals, and the environment. For example:
-
Blue-rich light may contribute to light pollution and disrupt circadian rhythms.
-
Amber and red light have longer wavelengths, producing less glare and being more wildlife-friendly.
Amber LED Lighting for Environmental Protection
Amber light sits between yellow and orange on the color spectrum and is especially useful in coastal lighting applications. Sea fish and other wildlife are less affected by long-wavelength light sources. Research shows that Amber LED lighting significantly reduces disorientation in baby sea turtles, helping them safely reach the ocean.
Unlike standard white lighting that contains a high amount of blue wavelengths, properly shielded amber LEDs reduce glare and minimize ecological disruption. They are ideal for environmentally sensitive zones such as:
-
Coastal habitats
-
Nature reserves
-
Parks and dark-sky regions
Conclusion
With the increasing global focus on sustainability and wildlife protection, understanding the visible light wavelength chart is becoming crucial in LED lighting design. Choosing the right LED wavelength not only fulfills client requirements but also protects natural ecosystems.
