The utility model provides an LED timing and sectioning dimming control device. A sending main controller comprises an MCU and controlled silicon which are electrically connected; display screens, a light opening button and signal receiving modules are arranged on the MCU; the receiving controller comprises a voltage detection resistor, an optical coupler, an MCU, and a switch power supply which are electrically connected; a capacitor is directly or indirectly arranged on the MCU; and the switch power supply is connected with controlled objects. For a switch signal of the control device, the sending main controller drives an AC contactor to replace a manual switch, the speed of switching can reach within 0.2 second, at the same time, the capacitor of the switch power supply has the characteristic of storing power energy, so that a user's naked eyes can not perceive the extinction of the controlled objects; and besides, only the sending controller is required to be set, and the convenience and practicality are achieved.
Description
Technical field
The utility model relates to the LED control device, and a kind of specifically LED is the sectional dimming control device regularly.
Background technology
LED street lamp and LED commercial lighting are energy-conservation; Simple method is to adopt regularly segmentation that the brightness of light fixture is regulated; Present employed light adjusting and controlling device has dual mode: the one, to transfer the files through the hand switch switching, and another kind carries out timing automatic at light fixture the inside adding single-chip microcomputer and transfers the files.Though both structures are all simple, and are with low cost, need not arrange holding wire; Need can not realize the lamp brightness adjusting through communicating wireless signals control yet; To reach power saving function, still, the former is because of MTS in will be at a fixed time; Can knock out at switch off period light fixture, many occasions do not allow the generation of this phenomenon thereupon yet.Though the latter can avoid the former defective, the time of timing dimming is what to preestablish in the controller of light fixture the inside, can't change in the use, and this kind deficiency has also limited its application in many occasions.
The utility model content
To the deficiency and the defective of above prior art, the purpose of the utility model is to provide a kind of LED regularly sectional dimming control device.
The purpose of the utility model realizes through adopting following technical scheme:
A kind of LED is the sectional dimming control device regularly, comprising: the transmission master controller of electrical connection, A.C. contactor and reception controller; Said transmission master controller comprises micro-control unit, the controllable silicon of electrical connection, and this micro-control unit is provided with display screen, button and signal receiving module open the light; Said reception controller comprises voltage detecting resistance, optocoupler, micro-control unit, the Switching Power Supply of electrical connection, directly or indirectly is provided with electric capacity on this micro-control unit, and this Switching Power Supply is electrically connected with the Be Controlled object.
As the optimal technical scheme of the utility model, described A.C. contactor is controllable switch element such as relay, controllable silicon.
As the optimal technical scheme of the utility model, said reception controller is provided with one or more.
As the optimal technical scheme of the utility model, said signal receiving module is switch key or wireless signal receiver module.
As the optimal technical scheme of the utility model, said Be Controlled object is the lamp string that a LED lamp or a plurality of LED lamp form.
Compare with existing hand switch sectional dimming; Because the switching signal of this control device is to drive A.C. contactor by master controller to substitute hand switch; Can accomplish on the switching speed in 0.2 second; The electric capacity of Switching Power Supply has the characteristic of storage of electrical energy simultaneously, and so down, user's naked eyes can't be discovered the Be Controlled object has the phenomenon of extinguishing; With timing sectional dimming compared with techniques; Because of only needing a master controller to add an A.C. contactor, whole engineering place power distribution cabinet to get final product; So set the brightness degree of whole engineering light fixture, the user only needs in power distribution cabinet master controller set and gets final product, and is convenient and practical.
Description of drawings
Fig. 1 is the regularly circuit theory diagrams of sectional dimming control device of the utility model LED.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
See also Fig. 1, be the circuit theory diagrams of the utility model LED timing sectional dimming control device.
This LED is the sectional dimming control device regularly, comprises transmission master controller 10, A.C. contactor 20, reception controller 30 3 parts of electric connection.
Said transmission master controller 10 comprises the micro-control unit 102 and controllable silicon 104 of electrical connection, and this micro-control unit 102 is provided with display screen 103, button and signal receiving module 101 open the light.This signal receiving module 101 is switch key signaling module or wireless signal module.
The switching of described A.C. contactor 20 direct control circuits can be relay, controllable silicon or switch element.
This receives controller 30 and handles and the driving switch output power of power supply for on/off detects; One or more reception controllers 30 can be set in the circuit; This reception controller 30 comprises voltage detecting resistance 301, optocoupler 302, micro-control unit 303, the Switching Power Supply 305 of electrical connection; Directly or indirectly be provided with electric capacity 304 on this micro-control unit 303, this Switching Power Supply 305 is electrically connected with Be Controlled object 306, and this Be Controlled object 306 is the lamp string that a LED lamp or a plurality of LED lamp form.
During this LED Light Control Unit work; Master controller 10 is according to the predefined time of user; Trigger A.C. contactor 20 and do the switch motion below the 0.2S, receive controller 30 existence because of direct or indirect electric capacity 304 during power down, can keep micro-control unit 303 and continue operate as normal; The power down time that micro-control unit 303 detects on the power line through voltage detecting resistance 301 and optocoupler 302; If detect the power down time greater than a certain numerical value, then start-up control Switching Power Supply 305 adjustment LED lamps 306 jump to another brightness degree immediately, reach the purpose of brightness regulation with this.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
