A double light source of insect killing lamp based on electrodeless lamp and LED

Abstract

The invention discloses an insect-killing lamp dual light source based on an electrodeless lamp and light-emitting diodes (LEDs), which relates to tools for trapping and killing injurious insects in agriculture, animal husbandry and forestry and application fields thereof. The insect-killing lamp dual light source comprises an electrodeless lamp light source, an LED light source and power supply circuit boards thereof, wherein ultraviolet light fluorescent powder with the radiation wavelength of 365nm is coated on about two thirds of the inner wall of the uviol glass tube of the electrodelesslamp light source; mercury titanium alloy (Hg-Ti)-containing amalgam is coated on the metal ring of a core column; the LEDs with different light-emitting colors of the LED light source are uniformly and alternately arranged on stripped metal core printed circuit boards (MC-PCBs); and the MC-PCB strips with the LEDs are arranged on each column surface of a regular hexagonal hollow columnar body radiating column. The dual light source which has a plurality of wave crests and the spectral range of between 250 and 650nm, emits light at 360 degrees and is powered by direct current is formed. The dual light source has high flexibility, high reliability, high radiating efficiency and long service life, the injurious insects can be effectively trapped in a full spectrum, and better insect trapping and killing effects can be achieved.

Description

technical field [0001] The invention relates to a tool for trapping and killing insects in agriculture, animal husbandry and forestry and its application field, in particular to a double light source of an insect killing lamp based on an electrodeless lamp and an LED. Background technique [0002] Agriculture and forestry have suffered from insect pests for thousands of years. Chemical pest control may be detrimental to environmental protection and food safety, and detrimental to the development of green and organic agricultural products. [0003] Utilizing the unique phototaxis of agricultural and forestry pests, using light to lure and kill pests is a common physical pest control method. In the past 30 years, electric light sources have been used to trap pests successively. The electric light sources used in turn include incandescent lamps, fluorescent lamps, and black lights. Later, high-voltage power grids built with electronic components were used to kill pests. In th...

AI Technical Summary

Problems solved by technology

First, the spectral range is narrow, the peak is single, and the spectral peaks sensitive to pests are different. For example, the peaks 270-290nm sensitive to some pests fall outside the spectral range of the light source, and the peaks 540-560nm sensitive to some pests are in the Within the spectral range of the light source, but there is no corresponding peak

The second is radiation efficiency, that is, the radiation power generated by unit electric power is low

The third is that with the increase of working time, the radiation intensity decays quickly, and the maintenance characteristics of radiation intensity are not good

Fourth, the life of the light source is short, and the life of the outdoor environment is about 3000 to 5000 hours

At present, the price of ultraviolet LEDs with a wavelength of 360-380nm, especially those with a wavelength of 270-290nm, is relatively high and their radiation efficiency is low. Simultaneously solve radiation efficiency and price issues and meet market application needs
