Description
Technical field
The utility model relates to lighting, particularly relates to the control circuit of the dynamo lighting set illumination of lighting carried charge segmentation display.
Background technology
Lighting, as the illuminating lamp on bicycle, is provided with dry cell or rechargeable battery for LED lamp bead and provides electric energy in light fixture, to throw light on road surface for making cyclist at night.But in use often can run into, the electricity in battery is once use up, and illuminating lamp just cannot throw light on, and has no omen before, this is very dangerous concerning the people in traveling.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, points out the control circuit of the dynamo lighting set illumination of eye-catching carried charge segmentation display.
In order to reach above-mentioned effect, the technical solution of the utility model is: it is characterized in that it is powered respectively to cpu control circuit, light-operated vibration detection circuit, supply voltage sample circuit, LED output and indicating circuit by power circuit; Push-button switch is had in cpu control circuit, control LED exports and the flash lamp mode of LED group in indicating circuit, the long switch that touches the button is the reserve of electricity detecting battery in power circuit, show through controlling LED output circuit again, the number shown in LED group represents the size of reserve of electricity, and the number of display more multilist shows that reserve of electricity is more; LED export and indicating circuit LED group in be provided with a low electricity warning LED; Cpu control circuit is connected to light-operated vibration detection circuit, in light-operated vibration detection circuit, is provided with vibroswitch and light-sensitive element; When having vibration and inadequate two signals of illuminance to cpu control circuit, the LED group of LED output and indicating circuit is lighted.
Described LED group has 5 LED, 5 bright expression battery electric quantities of lamp at 80-100%, 4 bright 60-80% of lamp, 3 bright 40-60% of lamp, 2 bright 20-40% of lamp, 1 bright less than 20% electricity of lamp.
According to the control circuit of the dynamo lighting set illumination of the carried charge segmentation display of technique scheme design, in use can adopt the long switch that touches the button, observe the storage situation of current battery charge, be provided with low electricity warning LED simultaneously, give prompting in time, user can take to change battery or pre-charged in advance, avoids the embarrassment of midway power-off.
Accompanying drawing explanation
Fig. 1 is the block diagram of the control circuit of the dynamo lighting set illumination of carried charge segmentation display;
Fig. 2 is the schematic diagram of the control circuit of the dynamo lighting set illumination of carried charge segmentation display.
In figure: 1, power circuit; 2, cpu control circuit; 3, light-operated vibration detection circuit; 4, supply voltage sample circuit; 5, LED exports and indicating circuit.
Embodiment
Below by embodiment, also the utility model will be further described by reference to the accompanying drawings.
Fig. 1, Fig. 2 are control circuit block diagram and the schematic diagram of the dynamo lighting set illumination of carried charge segmentation display respectively.As seen from the figure, it is powered to cpu control circuit 2, light-operated vibration detection circuit 3, supply voltage sample circuit 4, LED output and indicating circuit 5 by power circuit 1; Wherein cpu control circuit 2, light-operated vibration detection circuit 3, supply voltage sample circuit 4, LED exports and the VDD joint of indicating circuit 5 is all connected with the VDD joint in power circuit 1.LED exports and each P_LED1 to P_LED5 in indicating circuit 5 and P_LEDY wiring connect respectively at the binding post of correspondence markings in cpu control circuit 2.Light-operated vibration detection circuit 3 wherein, supply voltage sample circuit 4 are connected with cpu control circuit 2 respectively.
In cpu control circuit 2, there is a push-button switch S1 to control, for throwing light on and warning the flash lamp mode of LED group, the long reserve of electricity that can also detect lithium battery B1 in power circuit 1 by S1, and the LED group that 5 LED in LED output and indicating circuit 5 form shows, the number of LED display represents the size of reserve of electricity, the number shown more multilist shows that reserve of electricity is fuller, 5 bright expression battery electric quantities of lamp are at 80-100%, 4 bright 60-80% of lamp, 3 bright 40-60% of lamp, 2 bright 20-40% of lamp, 1 bright less than 20% electricity of lamp.Export at LED and be also provided with a low electricity alarm lamp in indicating circuit 5, be i.e. LEDY lamp wherein.Have in the pattern of lamp and automatically control shelves, a vibroswitch K1 is had in light-operated vibration detection circuit 3, when bicycle running, due to vehicle vibrations it provide vibration signal to cpu control circuit 2, also has a light-sensitive element Ry, when night, it provides the inadequate signal of illuminance to cpu control circuit 2, when cpu control circuit 2 receives this two signals simultaneously, just the LED group in LED output and indicating circuit 5 is lighted, that is night by bike time, LED group can be lighted automatically, does not need Push switch.
