what are the choice of solar street lamps controller? To introduce small make up to you today. I hope you through the introduction of this article, to be of understanding.

the solar street light controller is a important condition for the service life of the solar street light, if good control choice of solar street lamps, so no one can really control solar street lamps. First discusses the problems of the controller, the controller in the solar street light system 【 Solar street lamps system consists of eight elements. 】 , accounted for than low cost, is in 120 yuan - 200 yuan or so commonly, although look is a humble small objects, but bear the large role,, if you choose not to be able to make the whole system stability and service life, and a relatively mature controller can also be done by function to reduce the cost of the whole system, achieve the goal of cost savings.

in solar energy application of lamps and lanterns, LED lighting is the most suitable for through pulse width adjustment to achieve different power output. Control of pulse width or limit current at the same time, the duty cycle of LED lights the whole output adjustment, such as single LED7 string of 1 w 5 and total 35 w leds, discharge at night, late at night and early in the morning time can be separately power regulation, such as the middle of the night to adjust into 15 w, adjustment in the morning as 25 w, and lock current, which can satisfy all night lighting, and saving the cost of the panels, battery configuration. Through long-term test proves that the pulse width adjustment way of LED lights, the heat generated by the whole lamp is much small, can prolong the service life of the LED.

some lamp factory in order to achieve the purpose of save energy at night, make solar street light inside a two-way power, shut down power all the way to achieve output power at night by half, but the practice has proved that this method can only lead to half of the light source first droop, inconsistent brightness or light early damage on the way.
