Solar led street light quotation

LED technology is a popular technique, used in a variety of fields, such as building lighting, home lighting, or even a road lighting, and other aspects, the continuous development of LED lighting technology to solar street lamps, the following to introduce solar street light for you

LED technology is a popular technique, used in a variety of fields, such as building lighting, home lighting, or even a road lighting, and other aspects, the continuous development of LED lighting technology to solar street lamp, to introduce for everybody below is how to make the solar street lamps.

use solar power supply device for the play very interesting. This flash also won't let you down, let the solar gadgets work for several years!

flash circuit includes a rechargeable nickel cadmium battery.

when sunlight on the solar array is converted into electrical energy; Current through the diode, at the same time to the rechargeable battery and bulb flash device. During the day, that is, a light case, there is power in a charge for the flash device; At night, the light stopped, by storing in the electricity power supply. Only when no light so that the battery for a long time after the electricity, the device to stop work.

as shown, a common light-emitting diode ( 领导) Controlled by the integrated circuit LM3909. LM3909 have repeatedly switched on and off in all development need not diode circuits. 220 mu F capacitance is the timing capacitor led flashing.

a more simple type flash device can adopt CQX21 flashing light-emitting diodes (leds), all flash components needed to completely in the interior of light-emitting diodes (leds). CQX21 instead of in the figure LM3909, capacitors, and leds.

all in all, when the sun solar cells work when the power supply circuit. And if out of circuit nickel-cadmium rechargeable batteries, this device only in the sunlight or lamplight illuminate the battery to work. On the other hand, if you just want the batteries, remove the solar cell and diode. Figure leds can be used in any size and the color you have. Between the diode and the battery can be connected to the 12 flash device.

that is about how to make the introduction of solar street lamps, of course in his internal not just as simple as battery, there are some other equipment is what we don't know, but for his key is the battery. Solar street lamps, installation is simple and practical. Welcome to call the advisory.
