A solar power supply

Abstract

The invention discloses a solar power supply, comprising: a solar panel, an inverter circuit, a transformer circuit, a feedback circuit, a control circuit, a plurality of LED lighting circuits, a counting circuit, a first charging circuit, a second charging circuit, The charging control circuit, the solar battery panel includes at least one, connected to the transformer circuit through the inverter circuit, the input end of the charging control circuit is connected to the counting circuit, and the control signal is output according to the number of LED lighting circuits calculated by the counting circuit, The first charging circuit is controlled to charge the battery B1 in the LED lighting circuit, and the second charging circuit is controlled to charge the battery B2, and the battery B2 is used to supply power to the LED. The invention can supply power to LEDs through new energy sources, and by controlling the output voltage of new energy sources and according to the input quantity of LEDs, it can maintain constant current supply of outdoor LEDs and maintain the stability of LED power supply. Rational use of new energy can save energy.

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.
