the solar street light controller is an important condition of solar street lamps use life, if the solar street light control choose good, so no one can really control solar street lamps. First is the controller problem stop discussion, the controller in the whole system, solar street lamps of capital ratio is very low, average in 120 yuan - 200 yuan, is seems to be a small object of the humble, but bear the large role, if choose bad can let sell at a discount greatly the stability of the whole system and use life, and a relatively mature controller can also through the function to do to reduce the cost of the whole system, reach the purpose of saving money.

in solar energy application of lamps and lanterns, the LED lamp is the most suitable after pulse width control to complete the output of different power. Control of pulse width or limit current at the same time, the duty cycle of LED lights the whole output to stop nursing, such as single LED7 string of 1 w 5 and total 35 w leds, discharge during the night, to the middle of the night and early in the morning time stop power conditioning respectively, such as eyelid into 15 w, early in the morning in the middle of the night into 25 w, and lock current, which can satisfy all night lighting, and saved the panels, battery configuration. The long-term experiments proved that pulse width nursing methods of LED lights, the heat generated by the whole lamp is much small, can be LED to extend the using life.

some lamp factory in order to reach the purpose of save energy at night, make solar street light inside a two-way power, shut down power all the way to complete the output power at night by half, but the theory has been proved that this method is only half of the light source will incur the first light, LED street lamp, brightness differences or a light damage early.
