Description
Technical field
The utility model belongs to illuminating industry technical field, specifically, particularly relates to a kind of intelligent two grades of light modulation controller for road lamp.
Background technology
The regional rainy weather such as south China is more, when solar street light is often in illumination deficiency, solar street lamp controller common is on the market used if added, no matter street lamp is in " entirely bright " state the need of light always, storage battery works under being often in the state lower than 12V (24V), has greatly decayed the useful life of storage battery.Produce thus and realize street lamp design with an automatic light meter, when detect to have object movement near street lamp time, now street lamp throws light on according to optimal illumination power, can automatically enter base lighting state, i.e. " entirely bright " state.In brief, " car comes entirely bright, and car goes secretly bright in realization; People Lai Quanliang, people walks secretly bright " function, this is field of street lamp lighting or a blank at home and abroad.
Summary of the invention
The utility model discloses a kind of intelligent two grades of light modulation controller for road lamp, cannot dimming function be realized, the problem of life of storage battery deep fades for solving traditional solar street lamp controller.
The utility model is achieved through the following technical solutions:
A kind of intelligent two grades of light modulation controller for road lamp, comprise solar panel, illuminating lamp, storage battery, charging circuit unit, discharge circuit unit, switching power supply, body induction circuit unit and CPU light modulation main control unit, described solar panel is connected with storage battery through charging circuit unit, described storage battery is electrically connected with illuminating lamp through discharge circuit unit, described CPU light modulation main control unit comprises singlechip chip and peripheral circuit thereof, DC/DC converter, described singlechip chip utilizes pwm signal control DC/DC converter, be connected with the DC/DC converter signal of telecommunication, described DC/DC converter is electrically connected with illuminating lamp, described singlechip chip and peripheral circuit are also connected with the body induction circuit unit signal of telecommunication.
The model of described singlechip chip is Atmega8.
Described body induction circuit unit is infrared induction circuit or microwave radar sensor circuit.
Compared with prior art, the beneficial effects of the utility model are:
1. the pwm signal that produced by Atmega8 single-chip microcomputer of the utility model is to control the cut-offfing of illuminating lamp, Quan Liang, secretly bright;
2. the utility model circuit design is simple, and possess the function of " car comes entirely bright, and car goes secretly bright, people Lai Quanliang, and people walks secretly bright ", two grades of light modulations, easily realize secondary energy-saving, effectively reduce energy consumption, increase substantially service lifetime of accumulator;
3. the utility model DC/DC change-over circuit exports as direct voltage, illuminating lamp flicker free, brightness stability;
4. the utility model has very high use value, can be widely used in lighting field, is especially widely used in backroad illumination.
Accompanying drawing explanation
Accompanying drawing is the utility model schematic block circuit diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of intelligent two grades of light modulation controller for road lamp, comprise solar panel, illuminating lamp, storage battery, charging circuit unit, discharge circuit unit, switching power supply, body induction circuit unit and CPU light modulation main control unit, described solar panel is connected with storage battery through charging circuit unit, described storage battery is electrically connected with illuminating lamp through discharge circuit unit, described CPU light modulation main control unit comprises singlechip chip and peripheral circuit thereof, DC/DC converter, described singlechip chip utilizes pwm signal control DC/DC converter, be connected with the DC/DC converter signal of telecommunication, described DC/DC converter is electrically connected with illuminating lamp, described singlechip chip and peripheral circuit thereof are also connected with the body induction circuit unit signal of telecommunication.
The model of described singlechip chip is Atmega8.
Described body induction circuit unit is infrared induction circuit or microwave radar sensor circuit.
Charging circuit unit, discharge circuit unit, switching power supply, body induction circuit unit are prior art, and its annexation and function thereof are not repeated herein.
The hardware PWM module of Atmega8 single-chip microcomputer inside produces pwm signal, utilizes the switching tube in this pwm signal control DC/DC translation circuit, thus plays adjustment lighting modulating voltage.The function of Atmega8 single-chip microcomputer output voltage, compared with voltage and the setting voltage (lamp brightness) that are added on illuminating lamp, fine setting pwm signal duty ratio, makes output voltage stable and consistent more in real time.
Pwm signal duty ratio is signal high level time and the ratio in cycle, and modulating frequency is the inverse in cycle.When signal is high level, the P type field effect transistor conducting in DC/DC converter, to energy storage inductor, capacitor charging, when signal is low level, P type field effect transistor is ended, because electric current in inductance can not suddenly change, now fly-wheel diode conducting, for induction coil current and output current provide path.The value of output voltage can be changed by the duty ratio changing DC/DC convertor controls signal, thus change the brightness of illuminating lamp, achieve the function of street lamp " car comes entirely bright, and car goes secretly bright, people Lai Quanliang, and people walks secretly bright ".
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
