What to Know About UV Light Energy

Where light energy is concerned, you would find UV light energy to be quite prominent and popular. In terms of wavelength, you would find them to be shorter than visible light but longer than X-rays.

Even though a lot of UV radiation would be generated by the sun, you would not find it to be the only source. This is because a lot of artificial devices would also be able to generate these waves. Some of the most common ones would be as follows.

Black lights

These have been found to be the most common source of UV radiation. These kinds of lamps would generate UVA waves but with a very little amount of light which could be deemed visible. For instance, the black lights would use a phosphor coating on the interior of the glass tube. Higher grade black lights would also use the same principle. These would usually be used for theatrical displays and concerts.

 

Lasers

The lasers can be manufactured in a special way so that UV light could be produced. Based on the materials that could be used and the laser technology, the entire UV band could be covered.

In the case of applications of lasers, you would find the range to be quite diverse. Some of them would include dermatology, laser engraving, chemistry, keratectomy, optical storage, integrated circuit manufacturing, and communications.

 

LEDs

This would be one form of UV light energy which you might have heard a lot about. In today’s times, you would find it to be manufactured in a special manner so that UV light could be generated. These kinds of devices are normally being used for sterilization, UV curing applications, chemistry, and skin therapy.

 

Health issues

You would find that UV radiation would have a combination of beneficial and harmful effects on human health. When it would be used in moderation, it could be quite beneficial. Conversely, if you would be exposed to too much UV radiation, then it could be harmful.

Harmful effects

When exposed too much to UV radiation, it could be harmful to the skin, eye, and immune system. Other than that, it could also cause sunburn. In some cases, it has been found to be the cause for some kinds of skin cancer.

 

Beneficial effects

While the harmful effects of UV light energy seem to be highlighted the most, it would still make sense to look at the good side as well.

  • Vitamin D

When the human body would be exposed to UV radiation at a moderate level, then you would be able to get a healthy dose of vitamin D. this would help in the regulation of insulin secretion, calcium metabolism, immunity, cell propagation, and blood pressure. Thanks to your vitamin D being higher, it could result in lower stroke, heart disease, blood pressure, and diabetes.

  • Skin conditions

Specific skin conditions could be treated with the help of UV radiation. These would include dermatitis, eczema, atopic, localized scleroderma, rickets, psoriasis, vitiligo, and jaundice.

  • Hypertension and cardiovascular

Patients who would be suffering from a deficiency of vitamin D and a high blood pressure, exposure to UV light could help to reduce that.

 

Other Benefits to UV Light

UV light can be used to charge things. In fact many people run their entire homes off just UV light energy. This is used in conjunction with solar panels that collect the light from the sun, capture the energy and send it to an inverter which then converts that energy from a direct current into an alternating current. These types of systems can be found on this Power Portable Solar website.
