What is visible light communication technology? Visible light communication (VLC) is a data communications variant which uses visible light between 400 and 800 THz (780–375 nm). … The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s over short distances.
Also know What are the applications of visible light?
Aside from sight, there are other important uses for visible light. We concentrate visible light to make lasers to use in everything from surgery, to CD players to laser pointers. Visible light waves also make our TV, computer and cell phone screens work. Is Visible Light Dangerous?
Is visible light harmful? Visible light is typically pretty harmless. However, some light can be so intense that it can damage the receptor cells in your eye causing temporary or permanent blindness. High powered lasers can also be damaging and will cause burns.
Does visible light damage skin?
While visible light is far less damaging than other solar radiation, the effect is increased when damage from UVA opens up skin cells to further damage from other radiation. Visible light accounts for 45 per cent of solar radiation hitting our skin, while UV accounts for just five per cent.
Can Infrared be harmful?
Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.

Why is VLC only in LiFi?
➤LiFi is the short form of Light Fidelity and VLC is the short form of Visible Light Communication. ➤VLC technology uses visible light part of the light spectrum where as LiFi technology uses any possible light spectrum for communication. ➤There are many applications of wireless communication viz.
Which color carries the most energy?
The more energy a wave has, the higher its frequency, and vice versa. When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What happens when a person is exposed to visible light?
The visible light radiation can exert various biologic effects such as erythema, pigmentation, thermal damage and free radical production. Addtionally, visible light exposure can cause or exacerbate photodermatoses such as solar urticaria, chronic actinic dermatosis (CAD) and cutaneous porphyrias.
What are the negative effects of infrared radiation?
IR raises the internal temperature of the eye, virtually “baking” it. Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. Don’t stare at the sun! The infrared radiation in the sunlight damages skin.
Does infrared have radiation?
Infrared radiation (IR), or infrared light, is a type of radiant energy that’s invisible to human eyes but that we can feel as heat. … IR is a type of electromagnetic radiation, a continuum of frequencies produced when atoms absorb and then release energy.
Can computer screen tan your face?
Yes, you read that right—your computer is causing harm to the skin on your hands and face. … The screens of our smartphones, computers, and tablets, emit blue light that like UV rays increases the risk of skin disorders such as hyperpigmentation.
Does visible light cause aging?
Although many of us don’t pay a lot of attention to visible light, an emerging body of research suggests that this type of light, including blue light, can also cause skin damage. In particular, some studies suggest that it can cause or exacerbate signs of aging and hyperpigmentation, particularly melasma.
Is infrared good for arthritis?
Infrared Light May Be Useful in Controlling RA Symptoms
“Low level laser therapy is very effective symptomatic care, but it is not a curative. However, it does not involve injections, medication, or narcotics and is not painful, and is good at decreasing pain, inflammation, and swelling,” he says.
Can infrared blind you?
All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. The infrared light needs to be extremely intense to cause harm. … In extreme cases, if the eyes absorb too much infrared light, they can be irreversibly damaged.
Is infrared bad for eyes?
The most common eye disease associated with near-infrared radiation is cataracts. Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina.
