General Information about UV-lamps

The Ultraviolet light is classified in three ranges of wavelength:
UV-A from 315nm to 400nm
UV-B from 280nm to 315nm
UV-C from 100nm to 280nm

We can offer UV-A 360nm, UV-C 185nm and 254nm lamp. Customized products have a minimum order of 100pcs and 4-6 weeks lead time. Contact us your requested dimmensions for a quotation

UV-C Cold Cathode 254nm Germicidal Lamps
Quartz Germicidal Lamps are low pressure lamps that generate most of the energy at 254nm (253,7nm - Mercury line) and some energy at 185nm. In medical terminology they are known as UV-C lamps.

UV-C lamps are manufactured with quartz glass, and have traces of Mercury (less than 3mg per lamp). These lamps generate UV radiation at 254nm. There is also a small amount of Ozone generated by the residual radiation of 185nm and corona effect for all UV 254nm lamps.

Our 12V DC Inverters are designed to supply the lamp with the correct voltage.


As major applications we can mention:
  • Air Disinfection. It is recommended in the area commonly used by people suspected to be infected with Airborne transmitted diseases such us: physician waiting room, hospital waiting room, surgical, room, holding areas, treatment rooms, veterinary and pet facilities, and everywhere where people and/or animals are congregating. Since UV radiation is harmful to human eyes, it is mandatory to avoid direct exposure to UV radiation/light using proper mounting fixtures for these lamps. To accelerate the lamp germicidal effect it is highly recommended a good ventilation/movement of the air using a small fun that will mixed the treated with untreated air, diminishing the concentration of the air born microorganism and bacteria.
  • Air Ozonation. Ozone has odor neutralization ability. The UV-185 energy radiation breaks apart some of the Oxygen molecules (O2) into two radicals Oxygen (O-) that combines and forms Ozone (O3).The combined odor neutralization and germicidal effects make UV-C lamps a very low cost methode.
  • Water Disinfection. For many years it is very well known that one of the radiation effects at 254nm is water disinfection with no residual or side effect. Using the UV disinfection system will keep the water free of any bacteria or other organic materials that can grow. UV-254nm radiation is one of the most effective water disinfection method without any residual or side effects. The cost of operation versus chemical methode is very low.
  • Chlorine Removal. Exposing the water to UV-185nm generated by the quartz cold cathode lamps will also lead to a photochemical reaction similarly with the sun radiation. Through photochemical reaction the chlorine disassociates to chlorine ion
    (Cl-) and Hydrochloric Acid (HCl) which can be easy removed
    from the water.
  • Carbon Reduction. Semiconductor Processing Industry requires a high purity of water with no organic based components. The presence of carbon in water can be very efficient minimized exposing the water to UV -185nm germicidal radiation. Under UV radiation some of the water molecules are discomposing on H and OH. As OH radical is a very powerful oxidant all the residual carbon will be transformed in CO2. Typical dosage required may vary between 100mWsec/cm2 to 900mWsec/cm2
  • Sterilization Time. Sterilization time in second = Sterilization Dosage/Radiation Intensity Sterilization Dosage (uW, sec/cm2) = UV intensity * Exposure Time Radiation Intensity (uW/cm2) = UV Intensity / cm2. Our Miniature Quartz Cold Cathode lamps generate about 5mW/cm2 at quartz level. The efficient sterilization dosage for a certain surface that should be sterilized is: 10mWsec/cm2 / 5mW/cm2 = 2 seconds. This should be the total time that surface we want to disinfect should remain under UV radiation. To calculate the sterilization dosage for water or air we may need to take in account a certain number of factors such us: lamp intensity radiation, intensity variation within distance, the chamber size, the flow rate, the absorbtion coefficient of the media, etc
    .
CAUTION !!!

SAFETY CONCERNS:

• Although the amount of UV and Ozone generation is very small, we recommend all suitable precaution to avoid eyes or skin exposure to UV radiation. It can produce serious damage to the eye, which may lead to temporary or permanent vision impairment. For this reason, the light produced by a germicidal lamp must be carefully shielded against both direct viewing and reflections and dispersed light that might be viewed.
• Do not touch the glass/quartz with the bare hands. Rubber gloves are recommended.
• Use appropriate protection, wires and insulated materials to avoid surge voltage from the lamp leads. Do not touch plug with wet hands.
• Discard the lamps in accordance with safety code requirements for materials containing Mercury.
• When Lamp in use we recommend an adequate ventilation.
• Take also all suitable requirements recommended by the government safety code to avoid a prolong inhalation of Ozone generated by lamp.
• The operation risk is in Group 1 per ANSI / ESNA PR27.3-96.
• This lamp should not be used for cosmetic treatments, therapeutic or diagnostic purpose.
• This product is not a toy. Use and store out of reach of children
• Intended for indoor use only. Do not use the ballast in wet or dump conditions.
• Do not expose/use lamp, ballast and wires in excessive heat, moisture, humidity, condensation, and other weather elements.
• Only our lamps with water protected sleeve can be inserted in water up to the black flange.
