Abstract

This paper introduces the multi-functional lighting system which is a national undergraduate innovation training program. In view of the increasing energy shortage and environmental pollution, a multi-functional lighting system powered by solar energy is designed by project team members. In addition to the lighting function, the system also has killing insect and counting functions on some special occasions. This system uses STC90C516 as the control center, uses infrared diffuse reflection photoelectric switch and infrared human body sensor as the counting sensor, multi-color LED array as the lighting device, using the phototaxis of pests to attract pests and kill them with high-voltage power grid. The results show that the system is energy-saving, environmental friendly, accurate in counting, and has good insecticidal effect on many kinds of pests.
