1, in the electric power supply system, LED street lamp, in order to avoid the line loss during the process of sending and not resulted from the peak voltage is too low, often are based on high voltage transmission. Therefore, street lamp power consumed is higher, especially after midnight resources used when grid voltage is higher, excess voltage will only lead to greater calorific value, damage to the lamps and lanterns, and higher electricity bills. 2, high voltage instability or networks are clean ( Transient, harmonic etc. ) , which not only brings high electric bills, can lead to more light bulb fever and greatly reduce the service life of lamps and lanterns, maintenance and repair costs caused by increased dramatically. 3, according to the law of mathematical statistics in time and traffic, after midnight, people and vehicles to reduce, the requirement to the intensity of illumination decreased, at present has been used in the middle of the night lights manage way, but with the reduce of the load, the line voltage is higher, is bigger, to light up the lamps and lanterns of injury at the same time make the street lamp produces glare can increase the damage to person eyes, make the road uneven distribution of light, is not conducive to the vehicle's safety. 4, street lamp USES mostly gas discharge lamps and lanterns, which is given priority to with penetrating the strongest sodium lamp. Special physical characteristics determine the gas discharge lamp in only when starting, need high working voltage, and light after appropriate to reduce and stabilize the power supply voltage, can maintain its normal illumination, the patent technology for street lamp power saving provides a strong theoretical basis. 5, all gas discharge lamp is used in the process of using a 1. 6 - 0. 8 maintenance coefficient, make the brightness of lamps and lanterns than design value ( Life terminated brightness) Above 40 - 20%, when the light reaches the end of life, its brightness is just reach the target design value. According to this characteristic, the street lamp electric saving lamp compensation of the aging process, under the condition of guaranteeing the normal brightness of the light, to achieve power saving 25% - Another 40%, the street lamp power saving system theoretical basis. Acuity of illumination of 6, because the eyes is not a linear relationship, but a logarithmic relationship, after reaching sharp boundaries, into the 'visual blunt area', this time, Different from area to area, can set different time) More to reduce the brightness of the light, and won't affect the person's visual illumination, according to the energy saving can be realized.
