Energy-conserving Theft-proof Control System for Street Lamp
Description
Energy-conserving theft-proof control system for street lamp.It is regarding the microcomputer as the control center,according to the logarithm theory of the vision and luminous intensity(the luminous intensity is reduced by 10%,the vision is reduced by1%)and the mathematical statistics laws of time and vehicle pedestrian(It adopts half night-lights theories at home)consider the instability of the electrifield wire fence voltage in our country at the same time.It can accurately measure for the supplying power voltage and proceed the secondary optimized high-tech products,lengthen the light gallbladder and attachemnt service life effectively(1-3times)and improve the urban modernized scientific management of street lamp while saving the electric rate and prevent the street lamp cable from being stolen effectively.This not only brightens the street lamp facilitu energy-conservation and the safety magagement for the city,but also offers protection for economic development especially.Saving electric energy is 15%-50% in case of not changing in luminance,the fluorescent lamp is up to 15%of the economizing on electricity rate.As to the high-pressure sodium light tube is in no glisten and up to 50% of the economizing on electricity rate.As to the high-pressure sodium light tube is in no glisten and up to 50% of the economizing on electricity rate.Because of reducing the voltageto cause lighting glare,softer light and the more even illumination.It is a true green lighting.
Basic Principle
When the energy-conserving theft-proof control system of street lamp is started,the AC bypass switch is closed and started light source for 6-8minites directly by the municipal electricity.After the light source is steadied,the AC bypass swith is broken off,the module group will supply power for the light source im proortion.When the municipal electricity is on the high side or on the low side,PLC corresponding to reduce or increase the module quantity accordi |
