A kind of LED for effectively driveing mosquito
Technical field
This utility model is related to a kind of LED for effectively driveing mosquito.
Background technology
When entomologist studies the physiological property of mosquito, it is found that mosquito is especially sensitive to some light and likes, to other one
A little light are especially detested.According to this principle, by using special source material, the light that a large amount of mosquitoes do not like is produced, so as to
Reach the effect of expelling mosquito.As its mosquito repelling lamp for producing is to carry out expelling mosquito with visible ray, so to human body and environment
Harm without any pollution, is the high mosquito repellent product of domestic and international most safety and environmental protection at present.
It is known that daytime, mosquito all kept close, just out sting people in the evening.That is mosquito does harm in sunlight
The composition of fearness.Mosquito has different reactions to different wave length lamp:Eye can most be received, asthenopia is minimum, sees also most clear
The light wave of the 530-590nm wave bands of Chu, the backlight biological nature that mosquito has it intrinsic, it is to dislike this light or perhaps be afraid of this
Light is planted, has been seen;And the light of below 490nm, it is mosquito " welcoming light ", the photoproduction that becomes that mosquito has it intrinsic
Thing characteristic, under this light wave, it sees clearly, and likes living under this light wave.
LED mosquito repelling lamps have done a part in lamp the light wave that mosquito in sunlight does not like, so, in LED mosquito repelling lamps
Under, mosquito can be felt very ill, and it is not sudden towards LED mosquito repelling lamps, that is to say, that even if bright light windowing mosquito is not also toward interior
Fly, run into this light mosquito on the contrary and just escape, what interior was not escaped from just hides, have little time to hide just slowly disorderly flies in the air,
Slowly winged mosquito does not sting people, and this is also just not at all surprising.
The mosquito repelling lamp having had in prior art, or being the light using white light by filtration fraction wavelength(Mosquito is liked
Wave band light wave), the light wave of the 530-590nm wave bands that mosquito does not like is left, but, the mode of this spline filter wave band can be caused
Mosquito repelling lamp light efficiency is reduced;It is that employing can be launched in the LED chip of 450nm wavelength directly coating and can be launched 580-590nm ripples
The fluorescent material of Duan Guangbo, the luminous excitated fluorescent powder of LED chip produce specific band(The 580-590nm wave bands that mosquito does not like)'s
Light source, but it is possible to the fluorescent material heat resistance for launching 580-590nm wave band light waves is very poor, and the work of the mosquito repelling lamp of this structure
Temperature is high, and the temperature of fluorescent material is close to 150 DEG C, so optical attenuation is serious.
For problems of the prior art, based on the specific response that mosquito is produced to the light of specific wavelength, this practicality
New people specializes in and develops a kind of new LED for effectively driveing mosquito.
Utility model content
The purpose of this utility model is to provide a kind of LED for effectively driveing mosquito, to actually reach expelling mosquito
Effect, and operating temperature is reduced, improve optical attenuation, it is ensured that light efficiency.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of LED for effectively driveing mosquito, including lampshade, LED chip, aluminium base, lid, driving plate and lamp in radiating
Head, coating on lampshade inwall can launch the fluorescent material of 580-590nm wave band light waves, and lampshade is arranged on the lower section cover in radiating, dissipates
Lamp holder is installed in the top covered in heat, forms accommodating chamber on lampshade, radiating between lid and lamp holder, driving plate in accommodating chamber simultaneously
Electrically connect with lamp holder, during aluminium base is arranged on accommodating chamber and positioned at the lower section of driving plate, LED chip be arranged on aluminium base and with
Driving plate is electrically connected, and LED chip is towards lampshade.
The blue light excitation energy of the LED chip transmitting 450nm wavelength sends the fluorescent material of 580-590nm wave band light waves, sends out
Go out the yellow visible light that peak wavelength is 580-590nm.
The fluorescent material thickness coated on the lampshade inwall is 500 microns ± 10 microns.
The fluorescent material coated on the lampshade inwall, by weight percentage, is formulated by following raw materials according:Silica gel 14%,
Butyl ester 28%, 580nm fluorescent material 56%, 538nm fluorescent material 2%.
After such scheme, this utility model selects the mode that fluorescent material is coated on lampshade, luminous by LED chip
The 580-590nm wave band light waves that excitated fluorescent powder transmitting mosquito does not like, on the premise of light efficiency is ensured, make LED reach really
To the effect for driveing mosquito.Meanwhile, because the fluorescent material heat resistance for sending 580-590nm light waves is poor, this utility model is adopted
Coating method of the fluorescent material away from LED chip is taken, i.e. fluorescent material is coated on lampshade, lampshade temperature only has 50 DEG C or so, reduced
Operating temperature, so avoiding fluorescent material temperature drift and causing optical attenuation serious.

Specific embodiment
Coordinate shown in Fig. 1, a kind of LED for effectively driveing mosquito that this utility model is disclosed, including lampshade 1, LED chip
2nd, lid 4, driving plate 5 and lamp holder 6 on aluminium base 3, radiating.
Lampshade 1 is arranged on the lower section of the upper lid 4 of radiating, and in radiating, lamp holder 6,4 and of lid on lampshade 1, radiating are installed in the top of lid 4
Accommodating chamber is formed between lamp holder 6.
Driving plate 5 is arranged in accommodating chamber, and driving plate 5 is electrically connected with lamp holder 6.
Aluminium base 3 is arranged in accommodating chamber, and aluminium base 3 is located at the lower section of driving plate 5.
LED chip 2 is arranged on aluminium base 3, and LED chip 2 is electrically connected with driving plate 5.LED chip 2 is towards lampshade 1.LED
Chip 2 can launch the blue light of 450nm wavelength.
Fluorescent material 7 is coated on 1 inwall of lampshade, and the preferred thickness of fluorescent material 7 is 500 microns, and this fluorescent material 7 can quilt
The blue light that LED chip 2 sends is excited, and launches the light wave of 580-590nm wave bands(Yellow visible light).This fluorescent material 7 can be
What Hangzhou great Ming phosphor material powders company limited utility model made.Can also be prepared by following raw materials according by weight percentage
