Solar power supply

Abstract

The invention discloses a solar power supply, which comprises a solar panel, an inverter circuit, a voltage transformation circuit, a feedback circuit, a control circuit, a plurality of LED lighting circuits, a counting circuit, a first charging circuit, a second charging circuit and a charging control circuit, wherein the at least one solar panel is connected with the voltage transformation circuit through the inverter circuit; the input end of the charging control circuit is connected with the counting circuit; control signals are outputted according to the number of the LED lighting circuits calculated by the counting circuit; the first charging circuit is controlled to charge a battery B1 in the LED lighting circuits; the second charging circuit is controlled to charge a battery B2; and the battery B2 is used for supplying power to the LED. Power can be supplied to the LED through new energy, constant supply of the current of the outdoor LED can be maintained by controlling the voltage outputted by the new energy and according to the investment number of the LEDs, and the stability of LED power supply is maintained. New energy is reasonably utilized, and energy can be saved.

Description

technical field [0001] The invention relates to the field of solar power supply, in particular to a solar power supply. Background technique [0002] As a new type of energy-saving light source, LED lamps have been widely accepted and adopted by people due to their environmental protection, energy saving, long life, and small size. With the continuous improvement of people's living standards, higher requirements are put forward for the brightness and energy consumption of LED lights, whether at home or in stores, that is, people need to further increase the brightness of LED lights while requiring LED lights to have lower energy consumption. . And brightness control is carried out according to the lighting quantity of different LEDs, so as to achieve the maximum brightness control at the lowest loss or energy consumption, so as to meet people's needs for brightness and energy consumption. [0003] At this stage, the use of non-renewable energy is becoming more and more lim...

Problems solved by technology

[0003] At this stage, the use of non-renewable energy is becoming more and more limited. With the gradual use of new energy sources such as solar energy, there are many application scenarios such as street lights, and there are already a lot of solar energy used as the power supply for street lights. However, at present It is only extensive direct DC power supply, and the power supply cannot meet the situation of adjusting the number of LEDs when there are multiple LEDs that need different power supply requirements. How to stably supply new energy such as solar energy to LEDs, and maintain stable power supply while solar power is supplied This is the current technical problem. How to maintain the solar power supply is to maintain a constant current, etc., which need to be considered in the dynamic adjustment of future application scenarios.
