Description
Technical field
The present invention relates to technical field of lighting fixtures, relate in particular to a kind of intelligent energy-saving street lamp power supply circuits.
Background technology
Since the reform and opening-up, the group develops at a speed unheard of before along with Chinese city, the scale of city illumination facility is also increasing, the loss of road lighting is also risen thereupon, the frequent severe power shortage that occurs in recent years makes people pay attention to the energy-conservation of road lighting more, and existing lighting energy saving measure mainly is divided into following a few class:
The science of lamp stand is arranged, this method is mainly according to the industry standard CJJ45-2006 of the Ministry of Construction " city illumination design standard ", after having determined suitable lighting standard, according to the light fixture type of selecting, utilize point-by-point method or calculation software design to go out suitable road lamp system, the benefit of this method is that energy-conservation layout has been accomplished in maximization under the situation that does not relate to circuit itself, but defective also is apparent, the design of road lamp system relates to the light fixture arrangement form, the bar height, the street lamp spacing, numerous factors such as light source capacity and light fixture type, amount of calculation is huge, design is comparatively complicated, and must before construction, carry out, can not make amendment after construction is finished, relate to when changing light fixture in the aging maintenance afterwards along with street lamp, must change the light fixture of higher illuminance.
Staggered lamp-lighting method, this method adopts be when waiting demand lower after midnight the closed portion light fixture to reduce power consumption, the normal employing closed (or many) bright or close the method that road one side is lighted the road opposite side, the energy-saving effect of the benefit of this method is obvious, defective is to close (or many) bright must arrange two power cables simultaneously in construction initial stage road one side, and the basis is dropped into and strengthened; Closing road one side lights the method for road opposite side and can cause the brightness of closing a side to be starkly lower than " city illumination design standard ".And this method is when using abroad, runs into social environment when bad, and the crime rate of closing closed region once obviously raises, and this also is potential hidden danger.
The intelligence light source technology, intelligent light source step-down one voltage stabilizing one light regulating technology is the origin or beginning that device is installed in the street lamp distribution loop, controlling street lamp loop in the first half of the night is total head, near the time-division at midnight, begins to reduce loop voltage, the rare people of car further reduces voltage after a little while in the second half of the night.Its electricity principle has two, and the bright lamp of first high-pressure sodium lamp is kept voltage and is lower than 200V, therefore reduces the loop voltage light source and can not extinguish; It two is because the electrical network user is few after midnight, and it is low to load, and line voltage is higher than 220V, and overvoltage adopts this device then to avoid the waste of this part additive decrementation part electric energy, and according to engineering practice, its power savings is about 5%.Adopt this device, not only saved electric energy, do not influence uniformity of illuminance, and can avoid light source overvoltage operation, prolonged the street lamp life-span.The major defect of this method is: (1) is along with the increase of service time, electric parameters such as source ends voltage and electric current change, light source itself has discreteness qualitatively again simultaneously, just the phenomenon that some light fixtures are turned off the light in the same loop may occur when falling the voltage operation; (2) street lamp distribution loop radius of electricity supply reaches 800 meters, and along with the increase of light fixture and feeder ear distance, voltage descends gradually, if line design is improper, far-end voltage might occurs and can not satisfy the required voltage condition of normally keeping of light source; (3) tend to the illumination of external public transport platform advertising lamp box, telephone booth in the road lamp system, and these illuminations are generally adopted straight pipe type fluorescent lamp or compact fluorescent lamp because power is little, when being lower than normal power-frequency voltage, these light source cisco unity malfunctions.When (4) being connected to the electric lifting High-Pole Lamp in the loop, because electric device is perceptual starting characteristic, starting current is big, does not match with this device overload electrical characteristic.
Summary of the invention
