Advantages of UV LED

 > No IR radiation, less heat 

> More compact than mercury systems 

> Low voltage 

> No shutters or glass quartz 

 > Consistent and immediate UV output over operating life 

 > No UVC and therefore no ozone emitted, eliminating need for exhaust 

> Does not contain heavy metals (mercury) 

> Longer life, + 20,000 hrs as compared to 1,500 hrs on a standard UV mercury lamp 

> Easier to convert materials that are heat sensitive > LEDs are more efficient than mercury bulbs

Applications 

> UV-A type devices have been traditionally used in applications such as counterfeit detection or validation (currency, identification documents, etc). The actual wavelengths used are in the 390 nm – 420 nm range. As a result, these type of LED’s are readily available from a variety of sources and are considered the least expensive. 

> The middle UV-A LED area 350 nm – 390 nm are for curing both commercial and industrial materials such as adhesives, coatings and inks. There are many advantages over traditional curing technologies due to increased efficiencies and lower cost of ownership. Although the cost of this technology is greater, advances in manufacturing and demand are driving prices down. 

> The lower UV-A and upper UV-B ranges 300 nm - 350 nm are the most recent introduction to the marketplace. These units can be used in a variety of applications including UV curing and biomedical applications. There is a significant overlap in all three of the UV spectrum ranges, so consideration must be made in what is best for the application.

 > The lower UV-B and upper UV-C ranges 250 nm – 300 nm, is still in it’s early development stage. However, there is a great interest in these LED’s in air and water purification systems
