The detection end of the storage battery voltage detection circuit is connected to the storage battery, achieves electric quantity detection of the storage battery and feeds back a signal to the single chip microcomputer, the power source output end of the storage battery is connected to the power adjusting circuit, and the output end of the power adjusting circuit is connected to an LED lamp and supplies the electricity to the LED lamp. By means of the circuit for linearly adjusting the power of the solar street lamp, the output power of the street lamp can be intelligently adjusted according to the actual weather condition and the electric quantity change of the storage battery.

Description

[technical field] [0001] The invention relates to a linear adjustment solar street light power circuit. [Background technique] [0002] As an "inexhaustible and inexhaustible" safe and environmentally friendly new energy, solar energy has attracted more and more attention. The application of solar street lamps as clean energy is a very advantageous industry; [0003] However, the following main problems restrict the development of solar street lights: [0004] 1. The continuous power supply of the battery is the key to ensure the normal operation of the solar LED lighting system. [0005] 2. The brightness of a single lamp bead is uneven. When the power supply is low voltage, the light decays seriously, which affects the use effect. [0006] 3. In addition, solar LED street lights can avoid the cost and engineering volume of laying cables, and at the same time, a phenomenon occurs. Each set of street lamps is an independent body that operates independently, and there is ...

[0005] 2. The brightness of a single lamp bead is uneven, and when the power supply is low voltage, the light decays seriously, which affects the use effect

This is far from meeting the market's requirements for LED street lights

There are street lamp groups equipped with GPRS system control on the market. The disadvantage is that each set of GPRS needs to pay high communication fees to China Telecom, and cannot realize two-way communication, and cannot collect LED lamp usage and battery usage data.
