Abstract
A power control and energy-saving method for lighting system using discharge light source is suitable for large area lighting such as road or square, and features that the lighting system is powered by regulatable DC power supply and uses electric ballast able to work with DC, so controlling the voltage of DC power supply can regulate the power of lighting system and save energy.
Description
The invention relates to discharge light source lighting system, mainly is power control and energy-conservation a kind of method of large area lightings such as road and square.
Known, charging source is to utilize electric current to pass through gas or steam and radiative light source comprises fluorescent lamp, mercury lamp, sodium vapor lamp, Metal halogen lamp etc.Charging source generally has negative resistance charactertistic, need use ballast steady operation electric current for making the light source operate as normal, and provide light source to start required starting resistor.At present, charging source adopts the 50Hz electric main directly to power, and is the control lighting power, adopts single-circuit transformer formula voltage regulator to regulate alternating supply voltage, and power factor is low, and oneself power consumption is big, and volume is big, safeguards inconvenience, the cost height; Adopt controllable silicon to regulate alternating supply voltage, voltage waveform is poor, contains high order harmonic component, and the ballast loss increases.Simultaneously, charging source works in the 50Hz low-frequency ac, and supply power voltage descends suddenly and surpasses at 5% o'clock, and light source is " putting out " certainly easily.Therefore, present illuminator is not regulated supply power voltage.For the occasion that lighting powers such as road, square need be regulated, adopt the method for closing local light source to reach at present and regulate power and energy-conservation purpose.This method is easy to use, and cost is low, but illumination unevenness, the late into the night, supply power voltage raise simultaneously, caused the work of charging source overpower, and ballast power consumption increases, and light source life reduces.The Chinese patent specification, application number: 95117823.7, propose to adopt the stable DC power supply to improve the reliability of discharge light source lighting system, illumination stability, stroboscopic and realize continuous illumination, but the method for control lighting power is not proposed.
The present invention proposes to solve discharge light source lighting system control, regulates power and method for saving energy.At first change supply power mode, power with the illuminator that the scalable DC power supply replaces existing 50Hz electric main direct feeding system to form to charging source.Simultaneously, the used ballast of charging source adopts the electric ballast that can work in direct current to replace inductance type ballast commonly used at present.Utilize control direct current supply voltage method, change the voltage of input electric ballast, the power that makes electric ballast output to charging source changes, and reaches the purpose of power controlling and energy savings.The electric ballast common structure is to convert civil power to required direct voltage through AC-DC links such as over commutation, filtering, Active PFCs, by the DC-AC link, converts direct current to satisfactory 20KHz above high-frequency ac again.Adopt direct current directly to power, omitted the AC-DC link, reduce the power consumption and the production cost of ballast, improved reliability.Concentrated electric main is converted in the process of direct current, utilize controllable devices to realize the adjusting of direct current supply voltage.At present, concentrate the AC-DC conversion links to adopt methods such as controllable silicon phase control rectifier, voltage-regulation is easy, and is low in energy consumption, the reliability height, and cost is low.In a word, adopt the illuminator of electric ballast on a large scale, obviously be better than electric main with direct current supply and directly power.Design of Digital Ballast is output as the high-frequency ac above 20KHz, and under the high frequency state, the luminous efficiency of charging source improves, and the electric arc working stability is not easy " putting out certainly ", but operating power and voltage range enlarge.In addition, the electric ballast oneself power consumption is lower than Inductive ballast.Therefore, work in the full power state equally, the illuminator that adopts electric ballast is than the illuminator of inductance type ballast energy-conservation 20%.According to the present invention,, can save energy more than 40% by the control lighting power.

According to road lighting utility system of the present invention.This illuminator adopts 80 250W high-pressure sodium lamps as road lighting, lamp spacing 25m, gross power 20KW at full capacity.System adopts 350V direct current supply, the supply power voltage adjustable range be 150V to 350V, power regulating range 35%～110%.Be the no AC-DC link direct current supply 250W electric ballast that native system designs, when (circuit is seen Fig. 1) changes when extraneous supply power voltage, can regulate the power of supplying with charging source on a large scale.Actual measurement: input voltage 330V, output rated power 250W is 100% of rated power; Input voltage 270V, power output 175W is 70% of rated power; Input voltage 230V, power output 125W is 50% of rated power; Input voltage 190V, power output 87.5W is 35% of rated power; Input voltage 120V, power output 31W is 12.4% of rated power, steady operation.Between the lights wagon flow peak time, adopt the illumination of 100% full power; When in automobile, hanging down the magnitude of traffic flow, adopt power illumination in 80%～70%; When hanging down vehicle flowrate at dead of night, adopt 40%～50% low power illumination.The whole energy efficiency calculation is as follows:
Adopt the present invention, arrive the illumination power consumption between 6 early 6 of evenings:
Evening is during 6---9: (100% power) 20 * 3-60KWh
During 9---11: (70% power) 20 * 2 * 0.7=28KWh
4 o'clock mornings of 11--: (40% power) 20 * 5 * 0.4=40KWh
During 4----5: (70% power) 20 * 1 * 0.7=14KWh
