Description
Technical field
The utility model is a kind of intelligent universal light electricity-saving appliance, belongs to the economize on electricity product technical field, and especially the gas discharge class light fixture to the band ballast can provide automatically switch economize on electricity gear or twice economize on electricity control according to program that is provided with and user's requirement.
Prior art
The gas light fixture, places such as market, supermarket, hotel, airport, school, office building have been widely used in, also be used in street lamp, because the gas light fixture needs high voltage and heavy current when starting, after starting steadily, only need low voltage and electric current, and can not influence its illuminance, but have certain requirement, the voltage of supply too low then can influence its illuminance to the voltage of supplying with this moment, in order to improve the utilance of power supply, reach purpose of saving simultaneously.People wish to allow light fixture that higher voltage is arranged when starting, suitable its voltage parameter of control when operate as normal, as the electricity consumption place, the time period that has is to illuminance high request too not, then can improve its power utilization rate once more, thereby reach the effect of further economize on electricity.Such as, be street lamp in the first half of the night traffic can operate by the primary electricity-saving state of electricity-saving appliance more for a long time, and to vehicle, pedestrian's rareness after midnight, illuminance does not need when too strong, can put into for the second time that electricity-saving state operates,
At present, also there is producer that electricity-saving appliance is provided, but normally adopt the once technology of economize on electricity, also can only take the economize on electricity gear on the manual adjustment control transformer to adjust power saving rate even adjust power saving rate, adopt such regulative mode inconvenience when transferring the files also dangerous, simultaneously, this series products can't be obtained better power savings, still can bring certain loss, particularly when in some period light light being required just can't to bring higher power saving rate to the user not too high the time to the user.
Summary of the invention
The utility model purpose provides a kind of universal intelligent light electricity-saving appliance, can change power saving rate according to the loading condition operating state that automaticallyes switch by setup program, when avoiding because of manual the switching to user's influence and safety problem.Another purpose is that electricity-saving appliance itself can provide the secondary economize on electricity according to the program that is provided with, and plays better economize on electricity effect, has filled up and has only adopted the once vacancy of economize on electricity.
Based on above-mentioned requirements, the technical solution adopted in the utility model is: a kind of universal intelligent light electricity-saving appliance, comprise the Power Conversion unit, the control circuit that detecting signal unit and microcomputer control unit constitute, described Power Conversion unit is a transformer control circuit, primary coil one end of control transformer is connected with the zero line of power supply, the other end is in series with monolithic processor controlled contactor, the normally opened contact of contactor connects the power supply phase line, normally-closed contact is connected in the control circuit of contactor, the secondary coil of control transformer is between the input and output of power supply phase line, and described detecting signal unit comprises current transformer and A/D change-over circuit.Elementary (being the power supply phase line) of current transformer is series in the loop of load circuit, and secondary output is connected to input of single chip through the A/D change-over circuit, and described microcomputer control unit is single-chip microcomputer and peripheral circuit thereof.
In the brief introduction of top circuit, constitute main control circuit by single-chip microcomputer, single-chip microcomputer calculates the acquisition cuicuit parameter by the input signal to detecting signal unit, and the parameter of coming regulating circuit by control relay contactor and control transformer, to reach best power savings, during start, relay J 1, J2 is in normally-closed contact, the primary coil of instrument transformer (being the power supply phase line) constitutes the loop with the secondary coil and the load of control transformer by circuit breaker K2, can obtain detected value from detecting signal unit, but can not influence voltage, at this moment, the voltage of output is normal high voltage, gaseous discharge lamp begins starter work, through behind the setting-up time, gaseous discharge lamp all enters operating state, this moment, single-chip microcomputer output control relay J1 or J2 made it switch to normally opened contact, contactor KM3 or KM2 coil constitute the loop, the contactor adhesive, one end of control transformer primary return is communicated with phase line, can influence its secondary loop, thereby the voltage appropriateness is reduced and the operate as normal of maintenance gaseous discharge lamp, owing to suitably reduced its operating voltage, can effectively realize economize on electricity, the adhesive that single-chip microcomputer can control contactor on the other hand, thus the gear of control transformer regulated, achieve and automatically switch and secondary economizes on electricity.(because on the control transformer two grades of output voltages being arranged)
