Description

A kind of great power LED poultry cultivation lamp controller

Technical field

The application is related to LED technology application, more particularly to a kind of great power LED poultry cultivation lamp controller.

Background technology

With development and the maturation of LED technology, LED is applied in increasing field！Support in aquaculture, particularly birdss Grow in industry, the effect of LED is more and more obvious；At present, domestic LED light regulating technology mainly uses controllable silicon light modulation, But there is many in controllable silicon light modulation in actual applications：As controllable silicon is a kind of half control switch, electricity is only opened The function of stream, and electric current can not be complete switched off, though be adjusted to it is minimum still have weak current to pass through, and the luminous spy of LED micro-currents Property causes controllable silicon light modulation to deposit phenomenons of the LED still with the presence of Weak-luminescence after shut-off in a large number.The electric ginseng of different LEDs Number characteristic is different, exactly because the design so just to controller brings more higher requirements, controller zero passage detection Signal is inaccurate, and the angle of flow of the positive half cycle of silicon controlled and negative half period can be caused different, causes to trigger in advance or delayed touches Send out, cause LED to neglect bright suddenly dark, it is especially particularly evident when low-light level.

Prior art, dims for LED and generally adopts controllable silicon light modulation, but the controller that different LEDs needs Parameter be it is different, but currently on the market still for poultry cultivation industry LED and corresponding controller, The LED poultry cultivation lamp lamp controller stability for existing now is poor, in order to eliminate low-light level flicker, can typically reject 0-10% Brightness, by the flicker exported to avoid low-light level appearance for removing low-light level（But so fundamentally can not solve to ask Topic, and sacrifice low-light level output）；But this section of low-light level is exported in poultry cultivation, particularly broiler breeding industry has The meaning of particular importance：When chicken is ripe to be prepared to come out of steamer, workman needs to be transferred to very secretly light, and at this time human eye just may be used Chicken is grabbed to see, and chicken is also invisible, so it will not run chaotically when people goes to grab it.

The content of the invention

The main purpose of the application is to provide a kind of great power LED poultry cultivation lamp controller.

To reach above-mentioned purpose, poultry cultivation lamp controller, including：

Zero passage detection module, for detecting the zero point of 220V alternating current voltages；

Control module, for the zero signal detected according to zero passage detection module, determines controller triggering original position, Then IGBT circuits are driven, so as to reach the purpose of regulating illumination intensity；

IGBT drive module, the drive signal for being sent according to controller drive IGBT；

Rectification module, the alternating current for IGBT is exported are converted into unidirectional current, powering load；

Clock module, for carrying out timing to time date Hour Minute Second, can be with by the mcu programming of control module Time inside setting and reading clock chip, so as to the day-night change of simulated solar irradiation, it is adapted to the growth rhythm of birdss；

Key-press module, for adjusting the brightness of the LED being connected with controller, is reduced including brightness increase and brightness Key；

Display module, for showing current brightness degree in real time；

Power module, for providing running voltage to modules, wherein IGBT drive module is 15V voltages, and other are each Individual module is 5V voltages.

Compared with prior art, the technical scheme according to the application, first we specially design for poultry cultivation industry It is a kind of without the high voltage ac/dc LED for driving, this lamp the characteristics of be good stability, simple structure is cheap, both can be with Connect alternating current power supply, it is also possible to connect DC source.On the basis of this LED, we devise matched controller, this control IGBT as switching device, can both be controlled out by device processed, it is also possible to which control is closed, and no minimum load is required, therefore do not exist can The phenomenon that control silicon dimmer can not be complete switched off；Simultaneously using comparator detection zero-point voltage position, traditional optocoupler zero passage inspection Survey is compared, and the precision of detection is higher, and error is less, farthest ensure that the symmetrical of the positive-negative half-cycle angle of flow, so as to avoid The phenomenon flashed in dimming process.220V alternating currents are rectified into direct current, direct current output and nothing through rectification module by the application Driving high voltage ac/dc LED connection, design successfully it is a set of be more suitable for aquaculture industry, be more suitable for capacitive load LED dim Dimmer.
