Ultraviolet LED

BivarOpto has introduced what it claims is the industry's first extended-life high powered ultraviolet LEDs with typical radiant flux of 12 mW per chip and a typical stable wavelength of 400 nm.

The Ultraviolet LED series is housed in an all metal and glass TO-92 package that eliminates the life shortening degradation of the standard clear epoxy encapsulation.

The UV-400-TO 92 series is rated for over 20,000 hours of continuous operation at 30 mA compared with the typical life expectancy of 2000 hours for other devices. Viewing angle is 30° and the operating temperature range is -25 to +85°C.

The metal base is an effective heat sink offering increased forward currents up to 150 mA under 1/10th duty cycle operation. The series can also be specified with multi-chip configurations allowing for compound intensities up to 36 mW per unit and in large cluster arrays of up to 144 units per PCB.

Solid state UV emission provides increased energy efficiency, longer life, and resistance to shock and vibration than traditional, bulky, non-solid state UV lighting.
