Abstract
The invention provides a method and device for attracting insects by variable-frequency LEDs with different duty cycles. According to the method and device, a rectangular square wave with variable duty cycle and frequency is used as a control signal to control more than two LED beads to flicker according to the duty cycle and frequency of the rectangular square wave, so that energy can be greatly conserved due to different bright times and can be conversed maximally by over 50 percent on the one hand, and on the other hand, the LEDs are driven at different frequencies under the same duty cycle to achieve a good insect attracting effect. According to the invention, the effect of flicker at the flicker frequency of 45-65ms is superior to that of flicker at other flicker frequencies. Therefore, the insect attracting effect is promoted by utilizing the fact that insects have stronger phototaxis to a flickering light on the one hand, and on the other hand, compared with a single-color non-flickering light, the combined LED lamp columns have the advantage that the insect attracting range and insect attracting effect are greatly improved.
Description
Technical field
The present invention relates to technical field, especially a kind of different duty frequency conversion LED lures worm square law device.
Background technology
Most insects has phototaxis, so utilize light attract insect to be the cardinal principle of current insect killing lamp.But trapping lamp on the market, Mosquito killer lamp one series products all adopt monochromatic light, and do not glimmer at present, and the fluorescent tube that adopts as light source more, such mode its lure worm effect not ideal enough, and easily to damage.
Summary of the invention
The object of the invention is: provide a kind of different duty frequency conversion LED to lure worm square law device, it lures worm effective, and not fragile.
The present invention is achieved in that different duty frequency conversion LED lures worm method, rectangle square wave is exported by single-chip microcomputer, this rectangle side's wave frequency and dutycycle all adjustable, utilize this rectangle square wave as control signal, control two or more LED lamp bead according to rectangle square wave duty when frequency glimmer, thus realize luring insect.
The variable frequency range of rectangle square wave is 11.11 ~ 15.38Hz; Dutycycle is: 2:3.
LED moth-killing device, comprises controller, and controller is connected with amplifying circuit, and amplifying circuit is connected with lamppost, and power supply is connected with controller and amplifying circuit; Lamppost is provided with white led lamps pearl and purple LED lamp bead.
Described white led lamps pearl and the number ratio of purple LED lamp bead are 1:4.
On described lamppost, every 3 white led lamps pearls or purple LED lamp bead are one group, are the resistant series of 90-100 Ω with a resistance value, more in parallel each other.
Owing to have employed above technical scheme, the present invention adopts the rectangle square wave with variable duty when frequency to be used as control signal, control two or more LED lamp bead according to rectangle square wave duty when frequency glimmer, on the one hand, because the difference of light on and off time can be significantly energy-conservation, it is the highest energy-conservation more than 50%; On the other hand, when same dutycycle, with different frequency driving LED, can obtain and better lure worm effect, in the present invention, flicker frequency is better than other flicker frequency in 45 ~ 65ms its effect of glimmering.Its one side it makes use of insect thus has stronger phototaxis to blinking light, realize the lifting luring worm effect, on the other hand, it adopts knockdown LED post, compare single look, do not glimmer light, it lures worm scope and lures worm effect to have significantly to promote.Due to LED lamp bead compare ordinary incandescent lamp, its skill level of electricity-saving lamp is larger, even if not fragile under flicker condition yet, meet country using the important method of work as a sustainable development such as to develop a circular economy, save energy and reduce the cost, reduce the cost that government is used for government utility, can the active support of the government be subject to.The inventive method is simple, and easy to implement, with low cost, result of use is good.
