Description
The utility model relates to a kind of road lamp energy-saving device, belongs to the circuit arrangement that is used for general electric light source.
Now, high-pressure sodium lamp is used as street lamp more and more widely.The starter mode of this lamp is to use the big magnetoelectricity coil of inductance type as ballast.Ballast power consumption was original just quite big, and at dead of night the time, line voltage increases, and the electric weight that consumes on ferromagnetic ballast is just bigger.Though occurred the less electric ballast of power consumption now, because technology is still immature, electric ballast is also undesirable aspect life-span, cost, also can not all replace existing ferromagnetic ballast with electric ballast at present.
In street lamp energy-conservation, generally all consider people's car rareness when most of highway and avenue are at dead of night, the illumination that can reduce street lamp is with saves energy, but because high-pressure sodium lamp requires very high to its both end voltage, when dimming energy-saving, can not be used as conservation measures by reducing voltage, and whole electrical network can not reduce voltage also for this reason, to reduce with street lamp illumination allowable voltage at that time be contradiction in the increase of line voltage when this shows the late into the night.Therefore, preferably reach effect to its dimming energy-saving by the electric current that reduces to flow into sodium vapor lamp.
The purpose of this utility model is to overcome the weak point of above-mentioned technology and provides a kind of and do not need to change ferromagnetic ballast and just can realize the energy-conservation road lamp energy-saving device of timing dimming to high-pressure sodium lamp type street lamp.

The drawing explanation of accompanying drawing:
Fig. 1 is the utility model DC-stabilized circuit figure.
Fig. 2 is the utility model delay circuit figure.
Among Fig. 3, the part in the frame of broken lines is original high-pressure sodium lamp type street lamp connecting circuit figure; The frame of broken lines left side is the utility model governor circuit figure.
Now in conjunction with the accompanying drawings embodiment of the present utility model is further described:
As Fig. 1.The utility model D.C. regulated power supply input termination 220V alternating voltage, through the transformer step-down, the diode full-wave rectification, capacitor filtering adopts integrated regulator 7809 to produce stable 9V direct voltage, uses for delay circuit and governor circuit.
As Fig. 2.The multivibrator time-base circuit that the utility model delay circuit is made up of for the NE555 integrated circuit model, model are that the binary counter circuit formed of the integrated circuit of CD4520, switching transistor, relay and the resistance capacitance etc. that model is BUT11A are formed.The input of time-base circuit (5,6) is received the two ends of adjustable resistance (1), and the output of time-base circuit (3) is received the input of binary counter circuit, and the output Q7 of binary counter receives the base stage of switching transistor.Relay coil is connected on the collector electrode of this switching transistor.
As Fig. 3.The utility model governor circuit is that the two-way trigger of DB-3, controllable silicon and the resistance capacitance that model is 3CT are formed by relay tip J1, model.The control utmost point (15) of controllable silicon 3CT is received the end (12) of two-way trigger DB by resistance (13), and the other end of two-way trigger (11) is succeeded an end (8) and resistance (9) and the electric capacity (10) of electrical equipment contact J1.The other end of relay tip J1 (7) connects an end (14) and the 220V alternating voltage of controllable silicon 3CT.The utility model governor circuit is connected to when going in original road lamp device, with original road lamp power supply line from * disconnect, two ends (14 with controllable silicon 3CT, 16) serial connection is gone between the end (23) and ballast contact (24) of 220V power supply, be that contact (19) is linked contact (23), contact (20) is linked contact (24), and the ballast other end (27) is connected with an end (25) of starter; Contact (21) links to each other with contact (25), makes resistance (17) and electric capacity (18) and ballast constitute a loop, in order to absorb the peak voltage that ballast produces.Contact (22) links to each other with contact (26), and they are to exchange zero line.
Operation principle of the present utility model is as follows:
The utility model by shown in Figure 3 be installed in original road lamp device after, when adding the 220V alternating voltage, stabilized voltage power supply of the present utility model is promptly exported the 9V direct voltage for delay circuit and governor circuit work.Binary counter 4520 in the delay circuit just begins initialization after adding direct voltage, its initialization procedure needed for 20 seconds, in initialization imperfect tense, the output Q7 of binary counter 4520 is in low level, transistor (29) ends, no current flows through among the relay coil J, and therefore, the governor circuit repeat circuit contact J1 of Fig. 3 is not closed.At this moment, alternating current is given electric capacity (10) charging through resistance (9) in the governor circuit, and when being charged to the threshold voltage of two-way trigger DB-3, two-way trigger DB-3 output spike makes controllable silicon 3CT conducting once, and electric current enters ballast and gives the sodium vapor lamp preheating.In the 20 second time of binary counter 4520 initialization procedures, give electric capacity (10) charging continuously by alternating current, sodium vapor lamp obtains 20 seconds little current preheating time.After the energising through 20 second time, binary counter 4520 has been finished initialization, output Q7 upset the becoming high level of binary counter, make transistor (29) conducting, relay coil J energising, thereby make governor circuit repeat circuit contact J1 closure, the controllable silicon normally is normally lighted street lamp (28).
See the utility model delay circuit again.In this circuit, the characteristics of binary counter integrated circuit (IC) chip 4520 are that its input cp holds every input 2
8During individual pulse, just upset is once for the voltage of its output Q7.After the utility model added power supply, the multivibrator time-base circuit NE555 in the delay circuit just began main pulse when binary counter 4520 sends.Adjust the resistance (1) of multivibrator time-base circuit NE555, making output (3) the output pulse period of NE555 is 6 * 60/2
8=1.4 minutes, then through 2
8* 1.4=360 minute=6 hours, promptly the input of chip 4520 just received 2 after 6 hours
8Individual pulse, its output Q7 overturns once.At this moment, the relay tip J1 in the governor circuit disconnects once more, and the "on" position of governor circuit is identical with dress attitude in the initialization procedure, that is to say, street lamp through normal illumination in 6 hours after, change little illuminated into, make that the illumination of street lamp reduces after midnight, reach purpose of energy saving.Electric capacity in the delay circuit (2) and resistance (4) play reset response, and its effect is once sending a telegram here chip 4520 to be resetted, and guarantees that 4520 output Q7 is turned into low level by high level after 6 hours, make relay coil J outage.
The utlity model has following advantage:
1, the utlity model has considerable energy-saving effect, if by economizing on electricity every day, energy-saving effect can reach more than 30% 6 hours time. For 250W street lamp commonly used, in 0.50 yuan of every degree electricity charge, but 82 yuan of 1 year power cost savings of every lamp, by 78 yuan of the utility model sale prices, 1 year is recoverable cost, thereby guarantees in use profit necessarily of road lamp management unit.
2, the utility model can be protected sodium vapor lamp effectively. Because it has 20 seconds preheating time after adding power source; After midnight again load shedding illumination, so sodium vapor lamp life.
3, the utility model is cheap, and is easy for installation, and working automation makes road lamp management unit can realize effective management.
