Solar lamps are converted from solar panels to electrical energy.During the day, even in a cloudy day, the solar generator (solar board) was collected to store the energy required.Therefore, the sun generates energy to produce electricity.As a kind of "inexhaustible, inexhaustible" safety and environmental protection new energy, solar energy has received more and more attention.
Solar lamp circuit
Solar lamp circuits The principle of working: When there is solar light during the day, BT1 is converted from BT1 to electrical energy, which is charged by VD1 against BT2. Due to the light, the light -sensitive resistance is low, and the VQ4B is extremely low and cut off.In the evening, the time -free time -sensitive resistance was high resistance, VQ4 was turned on, and VQ2B was also very low. The DC boost circuit consisting of VQ3, VQ5, C2, R6, and L1 worked.The core of the DC booster circuit is a complementary tube oscillating circuit.
What brand of solar lights are good
Solar lamp brand: Langgi, Haige, ALWIL, Xinshuo Lianchuang, Xionghuo, HG (HG), Magic Iron, Kang Ming, Lomon, Adfenna, Miao Hut (Magicamah), Shanglong, HuayuanbieShu, Adfenna Finna and so on.
Solar lamp repair
If there is a problem with the solar panel in the solar lamp, the fault generally manifested that the lights are completely not bright.Just remove the solar lamp to make the solar panel work normally to see if there is a voltage existence and current passing.If not, it proves that it is the reason for the battery board, just replace it.
Self -made solar lamp
The principle of making this solar lamp is very simple, and it is clever and seductive: solar lights can store energy during the day and shine at night.Various colors (yellow, blue, red) lights can be available for ready -made, but they can also be made at home.A simple and low technical content, you need to buy a conventional solar paddock lamp and collect the light into a jar in nature.This is a simple design that simply designing a existing solar lamp to hang around the house or home.A person who is more savvy for electronics can adopt a more complicated way to use a small solar panel to make solar lamps on the ground. In terms of aesthetics, this may not be so good.
Solar lamp price
The price of ordinary solar lighting lights is around 50 yuan, and there are thousands of high -end.Solar lighting is based on the daylight of the day as energy. It uses solar batteries to charge the battery, and the solar energy conversion chemistry can be stored in the battery. When used at night, the battery is used as a power supply to provide energy to energy saving lights. The chemistry in the battery can be transformed into lightYes, let the lighting work.A basic solar lighting system includes solar cell panels, charging and discharge controllers, batteries, and light sources. It can directly generate low -voltage DC power, and can also be converted to 220 volts of communication with inverters, and then provides lighting loads.
