Detailed description of the invention
Below in conjunction with the accompanying drawings, preferably embodiment of the present utility model is described in further detail.
As it is shown in figure 1, a kind of electric motor intelligent lighting system, it includes that car light, mu balanced circuit, bleeder circuit, MCU control unit and switch mosfet, described bleeder circuit include that photosensitive bonder, described MCU control unit include VINPin, VRFPin, VOUTPin, after described mu balanced circuit is connected with the power supply of described electric motor car, described mu balanced circuit is connected with bleeder circuit, described bleeder circuit and the V of MCU control unitINPin, VRFPin connects, the V of described MCU control unitOUTPin, described VOUTPin is connected with car light by switch mosfet.
Detailed circuit diagram is as shown in Figure 2, described mu balanced circuit includes regulated power supply N1, described bleeder circuit includes resistance R1, resistance R2, resistance R3, electric capacity C1, electric capacity C2 and photosensitive bonder P1, the power supply of described electric motor car is connected with regulated power supply N1, described regulated power supply N1 is connected with resistance R1, resistance R3 simultaneously, with electric capacity C1, resistance R2, the V of MCU control unit while of described resistance R1RFPin connects, described electric capacity C1 and resistance R2 ground connection；Described resistance R3 simultaneously with the V of MCU control unitINPin, photosensitive bonder P1, electric capacity C2 connect, described photosensitive bonder P1, electric capacity C2 ground connection.Described car light is two, the respectively first car light lamp1 and the second car light lamp2, and described switch mosfet has two, respectively switch mosfet Q1, switch mosfet Q2, and described MCU control unit includes VOUT1Pin and VOUT2Pin, described VOUT1Pin is connected with switch mosfet Q1 by resistance R5, and described switch mosfet Q1 and the first car light connect；Described VOUT2Pin is connected with switch mosfet Q2 by resistance R4, and described switch mosfet Q2 and the second car light connect.Described switch mosfet Q1 and Q2 is N-type switch mosfet.
This technical scheme, regulated power supply N1 produces a V through electric capacity C1 filtering after the voltage stabilization of external change becomes the power supply of a 3.3V, resistance R1 and R2 dividing potential dropRFFixing reference voltage delivers to MCU control unit, and resistance R3 and P1 forms a potential-divider network and produce the voltage V of a change through electric capacity C2 filteringINDeliver to MCU control unit, because the photosensitive bonder of P1 is very sensitive to the power of light, as it is shown on figure 3, resistance diminishes when the intensity of light becomes strong, on the contrary then contrary, so voltage VINIt is as the strong and weak change of light.Car light Lamp1, Lamp2 are to receive MCU control unit V by Q1, Q2 and R5, R4 respectivelyOUT1、VOUT2Pin, works as VRFPin has been not detected by the presence of light then VOUT1、VOUT2Output voltage so that N-type switch mosfet is opened, Lamp1, Lamp2 lamp lights, simultaneously VOUT1、VOUT2Voltage output can be by the switch intensity of pulse-width modulation PWM form regulation Q1, Q2, thus scalable Lamp1, the light levels of Lamp2 light.
