Fluorescent powder used for LED mosquito-repellent lamp with high luminous efficiency

Abstract

The invention provides fluorescent powder used for an LED mosquito-repellent lamp with high luminous efficiency. The fluorescent powder comprises the following components in parts by mass: 0.01-0.03 parts of red fluorescent powder, 1-1.3 parts of yellow fluorescent powder and 5 parts of glue mixing powder. The dominant wavelengths of the emission spectrum of the fluorescent powder used for the LED mosquito-repellent lamp with high luminous efficiency are 570nm and 600m under the excitation of blue light with the wavelength ranging from 447.5nm to 460nm. Through the optimal design of the fluorescent powder composite, the mosquito-repellent lamp with the dominant wavelengths around 570nm and 600nm is obtained, and the 570nm and 600nm are the wavelength bands most abominable to mosquitoes. Compared with mosquito-repellent lamps on the market, the LED mosquito-repellent lamp provided by the invention has excellent mosquito repellent effect; meanwhile, the LED mosquito-repellent lamp with high luminous efficiency is provided with a light filtering element between a lamp bead and a lampshade for filtering out wavelengths below 520nm, thereby further improving the mosquito repellent effect of the fluorescent powder used for the LED mosquito-repellent lamp with high luminous efficiency.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a fluorescent powder for an LED mosquito repelling lamp with high light efficiency. Background technique [0002] Entomologists have found that many insects, such as mosquitoes, moths, and bugs, are particularly sensitive and prefer certain wavelengths of light, and are particularly disgusted with other lights. At present, most of the mosquito repellent lamps on the market are developed based on the principle that mosquitoes abhor certain wavelengths of light. The light sources mostly use ordinary incandescent lamps and fluorescent lamps. pollution. As people's requirements for the ecological environment and product health and safety continue to increase, traditional mosquito repellent products such as mosquito coils and mosquito-killing aerosols mainly use chemical drugs to drive and kill mosquitoes. Very big damage, gradually eliminated by the market. [0003] LED mosqu...

AI Technical Summary

Problems solved by technology

However, in the existing LED mosquito repellent lamps, ordinary LED light sources are directly used, which contain optics below 500nm. If no filter material is used to filter light with a wavelength of less than 500nm, it will in turn attract mosquitoes and greatly reduce mosquito repellent. The effect of the lamp, so the mosquito repellent effect is not ideal

Chinese patent CN201020661710.6 discloses a mosquito repellent lamp, which coats the LED diode with a yellow light barrier material, wherein the yellow light barrier material plays the role of emitting light, not the role of filtering wavelength, so it cannot filter wavelengths less than 520nm light, can not achieve better mosquito repellent effect

A high-efficiency mosquito repellent lamp disclosed in Chinese patent CN201410791866.9 has a wavelength range of 530nm-590nm. However, for mosquitos, moths, etc., it is the most disgusting, and the wavelength band with the best mosquito repellent effect is orange red. The light band, that is, the 590nm-610nm wavelength band, especially concentrated around the wavelength of 600nm, which also leads to the unsatisfactory repellent effect of the existing LED mosquito repellent lamps
