Embodiment
To combine accompanying drawing that the present invention is described further below.
See also Fig. 1; A kind of single lamp energy saving controller for road lamp 1 of the present invention has been shown among the figure; 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 with power ballast control interface 16 falls; 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; Through many lamp control expansion interfaces 14, but maximum expansion control to 4 street lamp.
In central processing unit 11, can work out corresponding Energy Saving Control program,,, control it and export corresponding lighting power according to different lighting hours requirements to the different functions group.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 the illumination condition that traditional separated small cup is turned off the light.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 get into the power energy-saving state that falls.According to the actual conditions of Qingpu, intend and 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 following:
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 through 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 through 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 on average economizes on electricity than waits 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.
More than combine accompanying drawing embodiment that the present invention is described in detail, those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
