The working principle of solar lamps
Left and right, charge and discharge controller to detect this voltage after the action, the battery on the lamp discharge! The simplest said: solar panels will absorb solar energy and converted into electricity after the power reserve battery for night use.
The use of photovoltaic effect of the principle of solar solar panels solar solar panels to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to 10lux or so, the solar panel open circuit voltage 4.5V
Aluminum alloy lamp column is made of aluminum alloy, belong to the metal material, so the correct statement; B. nitrogen chemical nature is not lively, can be used for protection in the bulb, so the correct statement; C. organic synthesis materials must have three characteristics
