Abstract
The study mentioned a curing equipment with UV LED array based on pyroelectric sensor and AP3706, which is based on the primary side control circuit so that it can complete the LED array constant voltage constant current output.the light source drive can output the constant voltage and constant current. The sensing signal processing signal integrated circuit BISS0001 as the pyroelectric sensor amplifier circuit as core, with relay making up the protection module of curing device. The experimental results show that, the curing equipment can realize the stable and homogeneous UV output, and when a human body in front of LED, the array will disabled to keep the human body away from damage UV induced.
