Antwort Is purple light UV? Weitere Antworten – Are purple light and UV light the same
Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of "purpler-than-purple" light or "beyond violet" light. Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum.With a wavelength of between 380 and 450 nm, purple UV light has the shortest wavelength.As a result, 415 nm (visible, violet light) LEDs and 405 nm (borderline visible violet light) are often used as "ultraviolet" LEDs. If a seller or manufacturer does not list the wavelength used – be careful – as they could very well be using a violet or purple LED that is not a true UV light source.
Is purple light bad for sleep : The worst colors for sleep are: Blue light: Suppresses melatonin production and pushes back your circadian rhythm, making it harder to fall asleep. Green light and violet light: May disrupt sleep, but more research is needed. Any light at night: Can keep you up and be harmful to your health.

Is purple high wavelength : WAVELENGTHS OF VISIBLE LIGHT
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
What's the Problem with Purple LED Lights Purple LED lights aren't really purple, but rather red and blue combined. Studies show blue lights interrupt our circadian rhythm, affecting sleep by suppressing melatonin production. Meiser says blue lights contribute to migraines and visual fatigue, too.
Purple LEDs are ultraviolet and they can be used to create a blacklight effect. Though you can make a brighter purple by mixing red and blue on an RGB LED, it won't have the same effect as the ultraviolet lights used in counterfeit bill detectors and for revealing security holograms on credit cards and driver licenses.
Are purple lights safe
Are the purple lights a safety concern Even though the purple lights are not the correct color, they still illuminate the area and don't pose a risk to the public.violet
Ultraviolet light gets its name due to the “violet” color it produces in the visible portion of the spectrum although much of the output of UV light is not visible to the human eye.Violet (color)
| Violet | |
|---|---|
| Wavelength | 380–435 nm |
| Frequency | 790–690 THz |
| Color coordinates | |
| Hex triplet | #8F00FF |
In order from lowest frequency to highest, they are red, orange, yellow, green, blue, indigo, and violet. Because of the inverse relationship, they are reversed in order by wavelength. The color with the highest frequency is violet.
Is LED light UV : Some in the lighting business have stated that LEDs do not produce UV radiation. However studies have shown that standard LEDs do create a small amount of UV. That said, the amount of UV they actually emit is even less. This is due to the phosphors within an LED lamp that convert the Ultraviolet light to white light.

Although most types of LED lighting do not emit any UV light, brilliant blues do emit a small amount. However, the phosphor reduces this to such a small fraction of the already small amount, the amount emitted is essentially negligible.Violet light has a wavelength between approximately 380 and 435 nanometers. The color's name is derived from the Viola genus of flowers. In the RGB color model used in computer and television screens, violet is produced by mixing red and blue light, with more blue than red.
Does purple light exist : We see violet when light comes into our eyes and triggers blue with a hint of red. On the flip side, purple doesn't exist anywhere along the light spectrum, so it isn't a “spectral” colour. Purple is a colour our brains create when an equal mix of blue and red light hit our eyes.
