Description
Technical field
The utility model relates to a kind of circuit design, is specifically related to a kind of indicator light control circuit.
Background technology
At present indicator light uses extensively in life with in producing, and acts on differently because use occasion is different, and adopting the LED light-emitting diode mostly is light source.Usually change according to the give out light difference of diode of LED, or light or glimmer or extinguish and come whether operate as normal such as indication equipment, device, and this class indicator light has a common fault, it is shinny that LED just begins starter during low-voltage, it is dark that just voltage does not reach the meeting of rated value light, can cause signal error to be judged when interference or induced current are arranged thus.Easily see in the use of existing indicator light to have two problems, indicator light do not have or seldom can display device, the different running statuses of machine etc., another be exactly indicator light under low-voltage with regard to the shinny consumed power of starter, and the phenomenon of erroneous judgement appears.
The utility model content
The utility model discloses a kind of indicator light control circuit at the weak point that prior art exists.
Indicator light control circuit disclosed in the utility model utilizes the different demonstrations of high-low level control indicator light, comes the different running statuses of indication equipment.This indicator light control circuit designs by following technical scheme: this circuit mainly comprises: backup battery, left side PMOS pipe, transport and placing device, right PMOS pipe, LED diode and peripheral capacitance resistance ware, the grid of described left PMOS pipe links to each other with incoming level, the source electrode of described left PMOS pipe links to each other with backup battery, the drain electrode of described left PMOS pipe links to each other with the positive power source terminal of transport and placing device, the output of described transport and placing device links to each other with the grid of right PMOS pipe, the source electrode of described right PMOS pipe links to each other with backup battery, the drain electrode of described right PMOS pipe links to each other with the LED diode, in the indicator light control circuit some peripheral capacitance resistance wares are set simultaneously, described transport and placing device and peripheral capacitance resistance ware constitute square-wave generator, the transport and placing device power supply processed of described left control pmos, the LED diode power supply processed of described right control pmos.
The negative power end ground connection of described transport and placing device.
The inverting input of described transport and placing device is by a capacity earth.
When described indicator light control circuit incoming level was high, left PMOS pipe ended, and transport and placing device does not have power supply, and square-wave generator is not worked, output low level, and the conducting of the right PMOS pipe of backup voltage resistance dividing potential drop rear drive, the LED diode continues to light, and keeps state kept burning day and night.
When described indicator light control circuit incoming level is the end, backup voltage resistance dividing potential drop rear drive left side PMOS pipe conducting, be the transport and placing device power supply, square-wave generator work, the output square-wave signal, right PMOS pipe drives and is square-wave signal, gives the power supply of LED diode with the square wave form, and the LED diode keeps blink states.
The beneficial effect of the disclosed a kind of indicator light control circuit of the utility model is: this circuit is by the two states of the corresponding indicator light of level difference of input two states, can utilize the different variable condition of indicator light to come the different running statuses of indication equipment, characteristics such as it is reasonable in design, novel, low in energy consumption that circuit design has.
Description of drawings
Accompanying drawing 1 is the circuit structure diagram of the utility model indicator light control circuit embodiment.
Embodiment
Below in conjunction with drawings and Examples, the disclosed indicator light control circuit of the utility model is described in further detail.
Embodiment:
Embodiment of the present utility model, the indicator light control circuit of preferred computer illustrates this circuit design, and as shown in Figure 1, described transport and placing device and peripheral capacitance resistance ware constitute square-wave generator, the transport and placing device power supply processed of described left control pmos, the LED diode power supply processed of described right control pmos; The grid of described left PMOS pipe links to each other with incoming level, the source electrode of described left PMOS pipe links to each other with the 5VSB backup battery, the drain electrode of described left PMOS pipe links to each other with the positive power source terminal of transport and placing device, the output of described transport and placing device links to each other with the grid of right PMOS pipe, the source electrode of described right PMOS pipe links to each other with the 5VSB backup battery, the drain electrode of described right PMOS pipe links to each other with the LED diode, described LED diode shows at device panel by the leaded light post, in the indicator light control circuit some peripheral capacitance resistance wares is set simultaneously.The negative power end ground connection of further described transport and placing device, the inverting input of described transport and placing device is by a capacity earth.
In the utility model embodiment indicator light control circuit, when incoming level when being high, left side PMOS pipe ends, transport and placing device does not have power supply, square-wave generator is not worked, output low level, the conducting of the right PMOS pipe of computer standby voltage 5VSB electric resistance partial pressure rear drive, the LED diode continues to light, and keeps state kept burning day and night; When incoming level when low, the PMOS pipe conducting of a computer standby voltage 5VSB electric resistance partial pressure rear drive left side is the transport and placing device power supply, square-wave generator work, the output square-wave signal, right PMOS pipe drives and is square-wave signal, give the power supply of LED diode with the square wave form, the LED diode keeps blink states.By this indicator light control circuit, the level of input height two states can be distinguished kept burning day and night, the flicker two states of corresponding indicator light, and then come the different running statuses of indication equipment, utilizing indicator light to pass through the leaded light post simultaneously shows at device panel, making that the two states of indicator light is more directly perceived easily distinguishes, improves the accuracy of judgment device running status.
Except technical characterictic described in the utility model, be the known technology of those skilled in the art.
