Anti-fly light barrier

Abstract

The invention belongs to the technical field of optics and relates to an anti-fly light barrier. Mosquitoes fear white light, while flies fear blue light; a plurality of white light sources and blue light sources are combined together and placed on focuses of two elongated parabolic lenses; light is gathered and emitted in parallel; one elongated parabolic lens is vertically arranged on one side of a doorway, and the other elongated parabolic lens is vertically arranged on the other side of the doorway; outer openings of the two elongated parabolic lenses face each other, so that light can bereflected infinitely, namely re-reflecting of light is achieved. The anti-fly light barrier has the advantages that the strong light barrier is formed by making use of light sources and can emit whitelight and blue light to prevent flies and mosquitoes from passing through the barrier, so that prevention of the mosquitoes and flies is achieved; the anti-fly light barrier is a non-physical barrier; people may access the doorway freely without injury; the anti-fly light barrier is simple in structure and convenient to use and can be used at flies and mosquitoes at home, schools, governmental organs, supermarkets, stations and the like to prevent flies and mosquitoes from spreading diseases and benefit people's physical health.

Description

technical field [0001] An anti-mosquito and fly light barrier belongs to the field of optical technology. Background technique [0002] At present, there are many kinds of anti-mosquito door curtains, such as magnetic door curtains, screen window curtains, plastic door curtains, etc., which cannot effectively prevent mosquitoes and flies from entering the room from the outside. When the door curtain is closed, mosquitoes and flies cannot enter the room from the outside. , the door curtain must be opened, and then mosquitoes and flies can enter the room from the outside. This is an inevitable situation at present, that is to say, the door is for people to enter and exit. At the same time, mosquitoes and flies just enter the room from the outside, and when people go in and out of the door, they must open the door curtain, which brings trouble to people, so this situation should be solved. Contents of the invention [0003] The problem to be solved by the present invention i...
