The new traffic lights factory analyze the traditional traffic signal lights, there are many defects, the existence of the reflective bowl led to false work, false work can cause serious traffic accidents; Life is short, the high cost of maintenance; High energy consumption. About the defect of traditional traffic lights, choose LED light source design of traffic lights, with strong visibility, low power consumption, energy saving, long using life, safety and operation safe reliable characteristic, so the traffic light has been more and more widely used at home and abroad. Traditional traffic lights usually selects the mains power supply directly, device to trench laying cable, to increase capital to traffic control device. New solar power system without stringing, rich in resources, the solar cell conversion power gradually progress, price decline gradually, is advantageous to the decline in capital, so has been more and more widely used. Choose single chip microcomputer control, improved system of sex, convenient installation, has major implications for ensuring the traffic safety。

 

Now, new traffic signal factory remind solar LED traffic lights work principle, solar LED traffic light by photovoltaic plates, charge and discharge controller, storage battery, LED traffic light system.

 

LED traffic light LED module circuit there are three kinds of cohesion method: the whole series, parallel, series and hybrid methods.

 

Briefly about the strengths of the whole series method is circuit, current flows through all the LED. After using the constant current source, can make the LED brightness. All defects: if there is a damage, the LED will not be able to work, making transformer high voltage and constant current source, the high capital money.

 

Electricity is the operational strength under full parallel method other leds. Briefly, lack of road LED damaged, will not affect the point: because the LED light source itself exists difference, floating voltage, parallel LED color is not uniform. Other, the current is too large, capital increase, brings to the power supply design also difficult, performance demand is higher, the output current very large voltage source.

 

Now countries vigorously to build a road, also played the "clean, energy saving type society", as long as the contact between the two for traffic traffic lights manufacturer, actively trying to set up different, talents has a bright future.
