UV LEDs Respond to Changing Medical Market Needs
A critical technology which will change the medical devices operate in the next 3-5 years is Light Emitting Diodes (LEDs). The ever expanding range of wavelengths and intensities will contineu to accelerate adoption by pioneering companies, particularly in the Ultra Violet (UV) range which is the low wavelengths from 10nm to 410nm.
Currently, UV LED technology can achieve as low as 365 nm and have been used for cosmetic applications and long term sterilization. However, as the wavelengths approach 280 nm, they are considered germicidal which is critical to purification of air and water, as well as other types of sterilization. At these wavelengths, they can alos be used in arrays for blood and other fluid analysis, curing for dental applications and spectroscopy.
Advantages:
-
Traditional UV Lamps may contain mercury which is hazardous to the environment, while LEDs contain no mercury and therefore are environmentally friendly.
-
LEDs offer greater energy savings, as they require much lower power consumption, making them ideal for a wide variety of hand held devices.
-
LEDs are much more compact, providing greater ease of design
-
The life cycle of an LED is significantly longer that traditional UV Lamps
-
LEDs provide a quick on/off, which is cruicial when requiring a fast response time for users that need to quickly act upon the medical information provided by a device
