How does a Bug Zapper Work? > 자유게시판

A best bug zapper zapper, more formally known as an electrical discharge insect management system, electric insect mosquito killer or (insect) electrocutor entice, is a machine that attracts and kills flying insects which can be attracted by light. A light source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a excessive voltage between them. The identify comes from the characteristic onomatopoeic "zap" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric fly zapper bat. Do cordless bug zapper zappers actually work? Bug zappers are normally housed in a protective cage of plastic or grounded metallic bars to forestall people or larger animals from touching the excessive voltage grid. A light supply is fitted inside, usually a fluorescent lamp designed to emit each visible and ultraviolet mild, which is visible to insects and attracts quite a lot of them. Newer fashions now use long-life LEDs to supply the sunshine. The sunshine source is surrounded by a pair of interleaved bare wire grids or helices.

The space between adjacent wires is usually about 2 mm (0.079 in). A high-voltage power supply powered by wall energy is used, which could also be a simple transformerless voltage multiplier circuit made with diodes and backyard mosquito control capacitors which can generate a voltage of 2 kilovolts or extra. This is excessive enough to conduct through the body of an insect which bridges the two grids, however not excessive enough to spark throughout the air gap. Enough electric present flows by the small physique of the insect to heat it to a high temperature. The impedance of the ability supply and the association of the grid is such that it can not drive a harmful current via the physique of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects; different models are designed to allow the debris to fall to the bottom under. Some use a fan to assist to lure the insect.
