Ultraviolet Germicidal Lamps

 

It has been known more than 100 years ago that Ultraviolet (UV) light has a germicidal effect. The natural source of UV light is the sun. It emits about 10% of its energy in the UV region. However, since it is mostly blocked by the earth's atmosphere it has no germicidal effect in our immediate environment, like our home's indoor air quality or our water systems.

Ultraviolet is a spectrum of light just beyond the visible range. UV light is divided into four ranges of wavelengths:

(1) Vacuum UV from 100 to 200 nanometers,

(2) UV-C from 200 to 280 nanometers,

(3) UV-B from 280 to 315 nanometers, and

(4) UV-A from 315 to 400 nanometers.

The UV-C spectrum (200 to 280 nanometers) is the most lethal wavelength for microorganisms, because it disrupts the chemical bonds between the atoms which, in biological terms, results in a "dead" microorganism. This range of wavelengths is also known as the Germicidal Spectrum. The germicidal spectrum is used to destroy bacteria, mold, viruses and other biological contaminants in the air, in liquids, or on surfaces.

UV light can be artificially generated by UV Lamps. UV Lamps are commonly referred to as Germicidal Lamps. Germicidal UV lamp purification has a long history and it is widely used for air purification, water treatment and surface disinfection purposes. It is a cost effective, environmentally friendly solution. Its effectiveness is directly related to intensity and exposure time. Ultraviolet germicidal lamps are low pressure mercury vapor lamps that are producing ultraviolet light by electrical discharge. The produced electromagnetic energy (UV light) has a lethal effect to microorganisms. Ultraviolet light is used in industrial and residential applications to purify water, air and surfaces.

The effectiveness of UV Lamp is limited by ambient temperature because of the inherent characteristics of the mercury. The most optimum ambient temperature range for standard low pressure UV lamp is between 65-85 °F or 18-29 °C. This means that if the ambient temperature goes below or above this range the effectiveness of the UV light intensity decreases. Depending on the application the UV lamps are normally protected inside of a glass tube to avoid large temperature changes.

Germicidal UV for Air Quality Breathability

Image
    Air quality and it's bacteria can be a serious concern. If you are one of those who suffer from allergies or asthma respiratory conditions you know that clean air is the most important. Not being able to breathe is truly scary. Germicidal UV can make the difference. Environmental Protection Agency (EPA) frequently reported that indoor air can be more polluted than the air outside. Whether you have a health condition or not, you could definitely benefit from breathing cleaner air with UV purifiers for your home.   How do these devices work? Germicidal UV cleaners use filters and Ultraviolet light to purify the air inside your home. You might be surprised but microscopic allergens like dust, mold, mildew, pet dander and pollen live in the same indoor area as you do. Air pollutants come from any source, furniture, rugs, carpets, toys, pets you name it and even the household cleaning product.   Maybe you are not one who suffers from these health conditions...

Ultraviolet Light and Its Biological Effects

Image
  Have you ever heard that ultraviolet (UV) light can be a biocide for living things? You can find the answer within the following info.   Starting with the history, the study on UV rays and its biological effects began around 1888 when Neils Ryborg Finsen decided to analyze this matter. He proposed that UV rays could kill bacteria. This discovery motivated other inventors to perform further analysis on this subject, including the mechanism of UV rays on microorganisms and applications in biology, medical sterilization, also air and water treatment.   UV (ultraviolet) light is part of electromagnetic spectrum which ranges from gamma rays to radio waves. The short wavelength and high frequency gamma rays are more energetic than radio waves which have long wavelength and low frequency. Therefore radio waves do not give bad effects no matter how long you are exposed to it. On the other hand, the short waves from gamma rays will be dangerous, even deadly.   O...
