LED light source with insect dispelling effect and insect-dispelling LED filament lamp

Abstract

The invention discloses an LED light source with an insect dispelling effect and an insect-dispelling LED filament lamp. The LED light source is formed by packaging a blue light chip and fluorescent powder, wherein the fluorescent powder includes the yellow fluorescent powder, the red fluorescent powder and the green fluorescent powder, the outer surface of the blue light chip is coated with the fluorescent powder, and the mass ratio of the yellow fluorescent powder to the red fluorescent powder to the green fluorescent powder is 1:(0.05-0.2):(0.05-0.2); the LED light source is prepared into a filament, and then the filament, a base and a bulb shell are assembled to form the filament lamp. The blue light component in the spectrum of the LED light source is smaller than millesimal, the filament lamp does not have the defects of promoting oviposition of insects on leaves and accelerating egg growth, and is high in excitation efficiency and luminous efficacy, and the luminous flux can reach 140 lm / w or above.

Description

technical field [0001] The invention relates to a light source for repelling insects, which belongs to the technical field of insect repelling devices, in particular to an LED light source with insect repelling effect and an insect repelling LED filament lamp. Background technique [0002] Crops will produce pests during the growth process. The problem of deworming has been troubled by people for many years. Nowadays, pesticides are usually used to drive out pests, but pesticides will remain on crops and cause damage to the soil, which will cause adverse effects on the environment and human beings. influences. Therefore, it is particularly important to find a product and method that can not cause harm to the human body and can efficiently repel insects and exterminate insects. Insect repellent lamps, also known as insect-proof lamps, emit yellow light above 450nm, which does not stimulate the flight of insects or use the bright adaptability of their eyes to prevent insects ...

Problems solved by technology

[0002] Crops will produce pests during the growth process. The problem of deworming has been troubled by people for many years. Nowadays, pesticides are usually used to drive out pests, but pesticides will remain on crops and cause damage to the soil, which will cause adverse effects on the environment and human beings. influences

Since blue light can promote insects to lay eggs on leaves and accelerate the growth of insect eggs, the spectrum of existing insect repellent lamps will contain blue light components, which will more or less affect the insect repellent effect

In addition, the existing insect repellent lamps have a series of defects such as short life, low efficiency, poor light effect, single function, unstable performance, and poor insect repellent flexibility.
