Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of single lamp energy saving controller for road lamp 1 of one of the present invention, be used to control street lamp, it comprises a central processing unit 11, and the street lamp operating state acquisition interface 12 that links to each other with this central processing unit 11 respectively, the street lamp electric current, voltage acquisition interface 13, many lamp control expansion interfaces 14, power carrier communication interface 15 and fall power ballast control interface 16, power carrier communication interface 15 links to each other with spread spectrum power carrier communication module 17, fall power ballast and control the employing of 16 interfaces by force, light current is isolated, 2 grades of drivings, it receives the switching value signal of central processing unit 11 outputs.In the present embodiment, central processing unit 11 adopts 8/16 one-chip CPU of technical grade, and has multiple function number incoming interface, and power carrier communication interface 15 adopts RS232 interface or RS485 interface, by many lamp control expansion interfaces 14, can expand controlling to 4 street lamps at most.
Can work out corresponding Energy Saving Control program 11 kinds of central processing units,,, control it and export corresponding lighting power according to different lighting hours requirements at different function groups.As: 1) under the normal condition, before midnight, the control street lamp is in normal full power output state; Late night to morning, control whole street lamps and be in and fall power output state, i.e. power save mode.2) before midnight, the control street lamp is in normal full power output state; Late night to morning, control whole street lamps and be in traditional illumination condition of turning off the light every small cup.3) before midnight, the control street lamp is in normal full power output state; Late night to morning, control crossing street lamp group is in normal illumination, and other street lamp groups enter the power energy-saving state that falls.According to the actual conditions of Qingpu, intend adopting: the normal illumination in back 3 hours of 1) turning on light; 2) turned on light 3 hours after, adopted before 0 o'clock midnight and fall 1 grade of illumination (reducing to 70%); 3) 2 grades of illuminations (reducing to 50%) fall in employing after 0 o'clock midnight; 4) turn off the light before half an hour get back to and fall 1 grade of illumination.
See also Fig. 2, single lamp energy saving controller for road lamp 1 respectively with building-out capacitor 2, fall power ballast 3, street lamp ballast 4, electronic trigger 5 and street lamp 6 and link to each other, falling power ballast 3 connects with street lamp ballast 4, and street lamp ballast 4 is connected with electronic trigger 5, street lamp 6 is connected in parallel on the two ends of electronic trigger 5, and its wiring sees also Fig. 2.
Its course of work is as follows:
1) under the normal condition, single lamp energy saving controller for road lamp (LCU) is controlled its internal electron switch, makes external voltage directly be added to (the L end is directly linked 3 ends, and 1,2 ends are unsettled) on the street lamp circuit, makes street lamp be operated in the rated power state.
2) under the road lamp switch control situation, LCU controls its internal electron switch, and the external electric pressure energy maybe can not be added on the street lamp circuit, and street lamp is opened or closed.
3) low grade is fallen under the power control situation, and LCU controls its internal electron switch, makes external voltage be added to (the L end is directly linked 2 ends, and 1,3 ends are unsettled) on the street lamp circuit by falling the power inductance centre cap.
4) top grade falls under the power control situation, and LCU controls its internal electron switch, makes external voltage be added to (the L end is directly linked 1 end, and 2,3 ends are unsettled) on the street lamp circuit by tap before falling power inductance.
When being in reduced power state, street lamp circuit inductive load increases, and the street lamp operating current reduces, thereby street lamp power is descended, and power consumption reduces, reach reduce meritoriously consume, energy-conservation effect.Simultaneously, because the effect of building-out capacitor, the power factor (PF) of whole street lamp has variation slightly, does not sacrifice reactive power, and road lamp equipment and road-light light-source are had no adverse effect useful life.
The present invention is on average economized on electricity than not waiting at 23%-45%, and energy-saving effect is preferably arranged.Simultaneously, have and do not have characteristics such as electromagnetic interference to the electrical network no-harmonic wave pollution, to environment.
