Outdoor Carpet

Solar outdoor lighting is the art and science of lighting up a place in the open air with the help of the energy contained within rays of sunshine. This is usually connected through the use of a solar cell battery made an element of lighting. A typical solar outdoor lighting device includes a plastic housing, nickel-cadmium battery, a solar cell on the top, a small circuit board and an LED and photo resistor.

The solar cells in solar outdoor lighting is a four --Solar cell, which measures about 2 inches square. The function of the solar cell is to convert the solar energy incident on them into electricity. The photo resistor is an electrical component, which play an important role in outdoor solar lighting plays. The function of the photo resistor is suitable recognize the darkness and turn on or off the outdoor solar lighting equipment.

In general, to produce a single solar cell about 0.45 volts. The power produced dependson the amount of sunlight falling on them and the size of the cell. In the solar outdoor lighting technology, the four cells in series, the cumulative voltage of 1.8 volts generates wired. In bright sunlight the solar cell production may be a current of 100 milliamps.

This solar cell is then wired to the AA-size NiCd battery that uses essentially the same as the batteries in cameras. A diode placed in between the battery and the solar cell prevents the current of flows back into the solar cell in the solar system, exterior lighting equipment. During the time of day is the battery charged by the sunlight falling on the solar array placed on the top. The battery charge reaches its maximum during the day.

In the meantime, to be done during night time, the solar cell does not produce electricity from lack of sunlight. The photoresistor senses that darkness has fallen, and automatically switches to the LED. One of the key components for solar> Outdoor lighting is the LED, solar outdoor lighting standard equipment, it produces about the same amount of light as a candle. Some devices with two LEDs and a halogen bulb. The halogen lamp is, if the light detects any movement in the vicinity is on. This is done by a motion sensor circuit placed inside the solar outdoor lighting equipment.

Solar outdoor lighting units are now much cheaper than 10 years ago, and prices will fallthe near future, and that's a very viable and environmentally friendly alternative to other forms of lighting.
