The present invention discloses an intermittent working discharge control circuit for a high-voltage arc discharge type insecticidal lamp. The circuit comprises an LM339 chip, a TL431 chip, an 8550 triode, a resistor, a capacitor, a chip U1A and chips U1B and ic2, and is characterized in that the LM339 chip is a core comparator, the TL431 chip sets a comparison voltage reference to be 2.5 V, the 8550 triode is a main execution element, and the resistor is provided with R1, R2, R3, R4, R5, R6, R7 and R8. The capacitor is provided with a C1, a C2, a C3 and a C4, the resistors R4, R5 and R6, thecapacitor C4 and the chip U1B form an oscillation circuit, the chip U1A is a control potential comparator, and the ic2 model is set to be TL43ILP. According to the intermittent working discharge control circuit for the high-voltage arc discharge type insecticidal lamp, a pure hardware comparator is used for charging and discharging to form a power supply of the oscillation control drive circuit, and the control mode is simple and reliable.
Description
technical field [0001] The invention relates to the technical field of insecticidal lamp control circuits, in particular to an intermittently working discharge control circuit for high-voltage arc discharge insecticidal lamps. Background technique [0002] Insecticidal lamp is a special device based on the phototaxis of insects, using insect-sensitive light sources in specific spectral ranges to trap insects and effectively kill insects, reduce the index of diseases and insect pests, and prevent and control insect pests and insect-borne diseases. It is mainly used to kill pests and reduce the use of pesticides. [0003] The prior art of the high-voltage arc discharge insecticidal lamp generally has the problems of large loss and low reliability. Especially in the case of strong interference from arc discharge, the control system is prone to problems such as control disorder. The existing insecticidal lamp control system generally does not control the high-voltage discharge...
