The intelligent control unit is for controlling output; the power factor correction unit is for increasing the power factor; the inductive ballast unit is for inductive ballast to drive a connected street lamp; and the starter unit is for starting a high pressure sodium lamp. According to the technical scheme, based on conventional inductive ballasts, the ballast can achieve automatic power transition at a preset time, so that intelligent light modulation can be fulfilled without manual intervention.
Description
Technical field
The utility model belongs to power electronics application technology and field of energy-saving technology, is specifically related to a kind of multi-functional sodium vapor lamp inductance and becomes power ballast.
Background technology
According to global market, in recent years along with the variation of the whole illumination market demand environment of China, street lamp market also has a very large change the demand of ballast, but the road lamp energy-saving ballast on market is all traditional Inductive ballast mostly, and mostly do not there is intelligent dimming function, the electric ballast cost with intelligent dimming function is relatively high again, and green illumination is wanted to implement in the area that some economy is relatively backward, but cannot pay the cost of great number.
Summary of the invention
Technical problem to be solved in the utility model is for existing market demand and the deficiencies in the prior art, provides a kind of lower-cost, has multi-functional sodium vapor lamp inductance energy-conservation, light modulation feature and becomes power ballast.
The technical solution of the utility model is as follows:
Sodium vapor lamp inductance becomes a power ballast, wherein, comprises intelligent control unit, the power factor correction unit being connected with intelligent control unit and inductance ballast unit, the starter unit being connected with described inductance ballast unit; Described intelligent control unit is used for controlling output; Described power factor correction unit is used for improving power factor; Described inductance ballast unit is as inductance ballast, for driving the street lamp of connection; Described starter unit is for high-pressure sodium lamp starter.
Described sodium vapor lamp inductance becomes power ballast, and wherein, described intelligent control unit, comprises time setting module, output control module; Described time setting module can require according to user the time of setting power conversion, and sends command adapted thereto to described output control module.
Described sodium vapor lamp inductance becomes power ballast, wherein, the power factor correction unit of telling, increase power factor compensation capacitance, is arranged on alternating voltage two ends, for the total harmonic distortion THD that controls described input current at preset range.
Described sodium vapor lamp inductance becomes power ballast, and wherein, described inductance ballast unit is as inductance ballast, for driving the street lamp of connection.Comparing its feature with traditional Inductive ballast is with centre tap, can change by described intelligent control module the inductance value of ballast inductance, and then change power output.
Described sodium vapor lamp inductance becomes power ballast, and wherein, described starter unit provides starting voltage by starter to high-pressure sodium lamp after energising.
Adopt such scheme, the utility model has not only solved the problem that prior art exists, and obviously has following advantage:
Cost is lower, simple in structure, and has intelligent dimming function, and ballast work is after midnight, and on road, pedestrian is rare, and program can change according to setting-up time the inductance value of ballast inductance, automatically carries out brightness adjustment control, reduces power consumption.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the variable ballast inductance partial circuit schematic diagram of the utility model embodiment;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1-2, the utility model, comprises intelligent control unit, power factor correction unit, inductance ballast unit and starter unit.
Intelligent control unit, comprises output control module and time setting module.Output control module is controlled by time setting module, and during to setting-up time, intelligent control unit changes output state, changes the inductance value of ballast inductance, reaches the object of energy-saving dimming.In intelligent control unit, setting module is controlled by toggle switch the time, is convenient to user's setting power conversion time on request.
Power factor correction unit, adopts the compensation way that increases building-out capacitor, is arranged on AC power two ends, and the sinusoidal waveform that makes the mean value of input current approach input voltage by power factor correction unit changes, and power factor can reach more than 0.88.
Inductance ballast unit, is one and is with tapped ballast inductance.By intelligent control unit, change Inductive ballast connected mode, reach the object of energy-saving dimming.
Starter unit, is a high pressure starter, and it obtains the high pressure of electric rear generation 3.5KV～5.0KV, lights high-pressure sodium lamp.
The whole course of work of the utility model is such: AC power, after power factor correction unit, obtains the alternating current of High Power Factor, and this alternating current is controlled and sent into inductance ballast unit through intelligent control unit, to high-pressure sodium lamp, powers.Rear end, inductance ballast unit is connecting starter unit, and starter obtains the high-voltage pulse of electric rear generation 3.5KV～5.0KV and lights high-pressure sodium lamp, and starter only starts moment work at high-pressure sodium lamp.When arriving the time of user's setting, intelligent control unit changes output state, changes the mode that ballast inductance seals in circuit, increase inductance, reduce power output, realize and regulate sodium vapor lamp electric current, reached the object of controlling sodium vapor lamp current energy saving, light modulation, finally realize energy-conservation.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection range of the utility model claims.
