Description
Technical field
The utility model belongs to electronic circuit and automatic control technology field, particularly a kind of traffic lights with brightness control function.
Background technology
In modern city, along with the sharp increase of population and automobile, urban transportation is day by day crowded, and traffic lights is one of important tool of traffic control division management urban transportation.Along with developing rapidly of electronics and computer technology, the design and study method of electronic circuit there occurs great change.Traffic lights are in the market core technology basis mainly with single-chip microcomputer greatly, auxiliary with the function of control, display, communication, timing.
Due to the vital role of traffic lights in urban transportation, the light source of current traffic signals command lamp is made up of multiple high-capacity LED, and occurs mainly with high light greatly.No matter daytime or brightness in evening all very high, especially evening, very dazzling, high brightness runs and also can produce the defect that energy consumption is high, the life-span is short always simultaneously.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of traffic lights with brightness control function, and when daytime has the surround lighting of high strength, enough bright, evening, brightness then suitably reduced by one, dazzling to avoid.In no matter daytime or evening, signal lamp both can be seen clearly, avoided again dazzling, also energy-conserving and environment-protective more simultaneously, added signal lamp serviceable life.
To achieve these goals, the technical solution adopted in the utility model is:
With traffic lights for brightness control function, comprising:
Be with the timer lighted;
The green LED signal lamp of reddish yellow;
For providing the power supply of electric power;
Environmental light intensity sensor;
The controller be connected with environmental light intensity sensor;
Connect the first via pwm signal of described controller output and first mosfet transistor being used as the power switching devices of described timer of power supply;
Connect the second road pwm signal of described controller output and second mosfet transistor being used as the power switching devices of the green LED signal lamp of described reddish yellow of power supply.
Described first via pwm signal is connected by hold with the G of power supply and described first mosfet transistor after the first sign-changing amplifier, and the S end ground connection of the first mosfet transistor, D holds and is connected with described timer.
Described second road pwm signal is connected by holding with the G of power supply and described second mosfet transistor after the second sign-changing amplifier, the S of the second mosfet transistor holds ground connection, D end is connected with the anode of the green LED signal lamp of described reddish yellow, and the negative electrode of the green LED signal lamp of reddish yellow takes back described controller.
Compared with prior art, the utility model can avoid the dazzling problem of the brightness of some period traffic lights, adds the comfortableness of eye recognition, decreases the energy consumption of traffic lights, extends the life-span of traffic lights.
Accompanying drawing explanation
Fig. 1 is the principle schematic of prior art.
Fig. 2 is principle schematic of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, existing traffic lights, controller only controls lighting of the green LED signal lamp of reddish yellow and timer, and brightness is changeless completely.
As shown in Figure 2, the utility model traffic lights, not only comprise be with light timer, the green LED signal lamp of reddish yellow, for providing power supply and the controller of electric power, also comprise environmental light intensity sensor, and environmental light intensity sensor is connected with controller; And connect the first via pwm signal of controller output and first mosfet transistor being used as the power switching devices of timer of power supply; Connect the second road pwm signal of controller output and second mosfet transistor being used as the power switching devices of the green LED signal lamp of reddish yellow of power supply.Wherein, first via pwm signal is connected by hold with the G of power supply and the first mosfet transistor after the first sign-changing amplifier, and the S end ground connection of the first mosfet transistor, D holds and is connected with timer.Second road pwm signal is connected by holding with the G of power supply and the second mosfet transistor after the second sign-changing amplifier, the S of the second mosfet transistor holds ground connection, D end is connected with the anode of the green LED signal lamp of reddish yellow, and the negative electrode of the green LED signal lamp of reddish yellow takes back controller.
According to structure of the present utility model, by the environmental light intensity sensor increased, controller can environmental light intensity measured by it, export two pwm signals respectively, first via pwm signal PWM1 controls the display brightness of timer, and the second road pwm signal PWM2 controls the brightness of the green LED signal lamp of reddish yellow.
The utility model utilizes PWM (PulseWidthModulation) to control---and pulse width modulating technology, by modulating the width of a series of pulse, obtains required waveform (containing shape and amplitude) equivalently.And mosfet transistor is as the switching device of power supply, contribute to raising the efficiency.
The utility model, when signal controls, introduces the measurement of environmental light intensity to external world, be not the light on and off of simple control LED in design, but environmentally the size of light intensity regulates the display brightness of LED in real time simultaneously.Meanwhile, in conjunction with actual test and standard-required, the contrast test of the brightness of light intensity and PWM can be carried out, draws optimum data.
