DC frequency oscillation pest-killing lamp tube starter

Abstract

The invention discloses a DC frequency oscillation pest-killing lamp tube starter, which comprises a fuse F, a starting circuit, a delay circuit, a rectifying circuit and a voltage stabilizing circuit; the fuse, the starting circuit, the delay circuit and the rectifying circuit are connected in series and in sequence; one end of the voltage stabilizing circuit is connected with a power side, and the other end of the voltage stabilizing circuit is connected with the rectifying circuit; and the starting circuit comprises an amplifier, a transformer, lamp tubes, a capacitor C2 and a capacitor C3, wherein a primary coil of the transformer and the capacitor C3 form a first LC oscillation circuit, a secondary coil of the transformer and the capacitor C2 form a second LC oscillation circuit, and the lamp tubes are connected to two ends of the capacitor C2 in parallel. The DC frequency oscillation pest-killing lamp tube starter has the capabilities of converting DC into AC to brighten the lamp tubes, prolonging the brightening / extinguishing time of frequency oscillation pest-killing lamp tubes and providing continuous and stable voltage and current for a frequency oscillation pest-killing lamp, thereby prolonging the service life of the frequency oscillation pest-killing lamp.

Description

technical field [0001] The invention relates to an insecticidal lamp used for exterminating pests in the agricultural field, in particular to a direct current frequency vibration type insecticidal lamp lamp tube starter. Background technique [0002] The frequency-vibration insecticidal lamp uses the characteristics of the phototaxis, wave-taxis, color-taxis, and taxis information of the pests to set the band and frequency of the light within a specific range. The sexual information generated by the pests themselves is used to lure the adults to hit the lamp, and the lamp is equipped with a frequency-vibrating high-voltage power grid to kill the pests, so that the pests fall into the insect-receiving bag (box) under the lamp to achieve the purpose of killing the pests. [0003] The frequency vibration type insecticidal lamps sold on the market all use starters to light them. The starter needs an AC voltage of 220V to ionize the inert gas and generate a glow discharge. The he...

AI Technical Summary

Problems solved by technology

The lighting time of the lamp tube and the extinguishing time of the lamp tube after power failure are all completed in an instant (less than 1S). Since there is no delay time for starting, the filament is easily burned out and the lamp tube is scrapped, thereby reducing the frequency of vibration. The service life of the insecticidal lamp; at the same time, due to the instability of the field voltage, the instantaneous high voltage is easy to burn out the circuit of the frequency vibration insecticidal lamp, and the low voltage will make it difficult to light up the frequency vibration insecticidal lamp
