Description
Technical field
The utility model relates to the energy-conservation LED power brick communicating circuit of a kind of LED power brick communicating circuit, particularly a kind of energy.
Background technology
In use, power brick electricity is finished rear needs and unloads the power brick not having electricity the LED of interchangeable power brick, is loaded on the power brick being full of electricity and turns on light and could use.When use can fill the LED of 2 power brick, 2 power brick parallel operations, need to use diode-isolated, isolating diode can produce very large power consumption, produce heating, lower efficiency, waste electric energy.
Utility model content
The purpose of this utility model is, provides a kind of LED power brick communicating circuit.The utility model can effectively control power brick time sharing power supply, does not waste electric energy on unnecessary device, reduces power consumption, improves service efficiency, saves electric energy.
The technical solution of the utility model: LED power brick communicating circuit, it is characterized in that: comprise power brick output interface, power brick output interface is connected with output control circuit, sample circuit and power circuit in turn, power brick output interface is also connected with communication interface and single-chip microcomputer, single-chip microcomputer is connected with communication interface, power circuit, single-chip microcomputer is connected with battery capacity indication circuit and keyboard input module, keyboard input module is connected with power circuit, is connected with lithium battery interface between described output control circuit and sample circuit.
In aforesaid LED power brick communicating circuit, described output control circuit comprises two PMOSFET devices be connected in series.
Compared with prior art, the utility model by single-chip microcomputer, output control circuit, communicating circuit, sample circuit, battery capacity indication circuit, the compositions such as power circuit.When after the input module that pushes button, can detect whether there is secondary cell bag by power brick output interface, if any secondary cell bag, Deng main battery bag electricity be finished after can allow secondary cell export power supply, thus can effectively control power brick time sharing power supply, do not waste electric energy on unnecessary device, reduce power consumption, improve service efficiency, save electric energy.PMOSFET device that the utility model also adopts two to be connected in series composition output control circuit, the conducting internal resistance of PMOSFET is very little, and when turning on light, consumes power hardly above, reduces power consumption further.The utility model also adopts the electricity of battery capacity indication Circuit display power brick, can intuitively understand power consumption situation.The utility model has easy to use and lower-cost feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is concrete enforcement schematic diagram of the present utility model.
Being labeled as in accompanying drawing: 1-power brick output interface, 2-output control circuit, 3-sample circuit, 4-power circuit, 5-communication interface, 6-single-chip microcomputer, 7-battery capacity indication circuit, 8-keyboard input module, 9-lithium battery interface, 10-PMOSFET device.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.LED power brick communicating circuit, form as shown in Figure 1, comprise power brick output interface 1, power brick output interface 1 is connected with output control circuit 2, sample circuit 3 and power circuit 4 in turn, power brick output interface 1 is also connected with communication interface 5 and single-chip microcomputer 6, single-chip microcomputer 6 is connected with communication interface 5, power circuit 4, single-chip microcomputer 6 is connected with battery capacity indication circuit 7 and keyboard input module 8, keyboard input module 8 is connected with power circuit 4, is connected with lithium battery interface 9 between described output control circuit 2 and sample circuit 3.
Described output control circuit 2 comprises two PMOSFET devices 10 be connected in series.
Described power brick output interface 1 is connected use with LED lamp holder; Described lithium battery interface 9 is for for whole circuit supply.
Described battery capacity indication circuit 7 comprises the some groups of light-emitting diodes be set up in parallel.
The utility model in the specific implementation, circuit as shown in Figure 2 can be adopted, operation principle is as follows: when battery packages is on lamp holder, push button after S1, single-chip microcomputer sends communication signal by communication interface circuit, if there is secondary cell bag, secondary cell feeds back to main battery bag after receiving communication signal, main battery can control the output control circuit of main battery bag after the signal receiving secondary bag, output control circuit is made up of 2 PMOSFET, because the conducting internal resistance of PMOSFET is very little, when turning on light, consumes power hardly above.Power to LED lamp holder after output control circuit output voltage, LED electricity is powered by main battery bag, then opens LED control signal, controls the brightness of lamp, until after main bag battery electric quantity is finished, signal to secondary cell, allow secondary cell bag control output control circuit and export cell voltage, after output circuit opened by secondary cell bag, main battery bag output circuit cuts out, LED electricity is powered by secondary cell bag, until secondary cell bag electricity is used up, and automatic shutdown.
If LED lamp holder only has a power brick, after the S1 that pushes button, main battery bag and the communication of secondary cell bag do not contact, and just enter monocell pack mode, until power brick electricity is finished, and automatic shutdown.
The utility model can effectively control power brick time sharing power supply, does not waste electric energy on unnecessary device, reduces power consumption, improves service efficiency, saves electric energy.
