UV LEDs COB
COB UV LEDs (chip-on-board) deliver very high optical output in a small area. The UV chips are bonded directly onto thermally conductive substrates and protected by a window cover. This enables high power density, efficient heat dissipation and stable performance in continuous operation. Available in wavelengths from 275 nm to 310 nm.
