Abstract

The intelligent solar lamp controller includes central control unit, which is connected vian a circuit comprising resistor, transistor and FET to solar cell, accumulator and load for reliable charge and discharge protection; and has partial pins capable of realizing light control and time control via different connection modes. The present invention has raised reliability of charge and discharge protection to avoid overcharge and overdischarge, and light control and time control of solar lamp with less time delay.

Description

technical field [0001] The invention relates to a controller in a lighting device, in particular to an intelligent controller of a solar lamp. Background technique [0002] In order to meet the needs of energy development and environmental protection, pollution-free renewable energy has attracted more and more attention. At present, as such a non-polluting renewable energy source, solar energy has been widely used in technical fields such as heating and power generation. Among them, solar lamps are lamps that use solar energy as energy. They are not affected by power supply lines, do not need to dig trenches and embed wires, and do not consume conventional electric energy. They are green and environmentally friendly light energy products. [0003] Solar lamps are generally composed of solar cell components, batteries, power controllers, and light-emitting components. The main system block diagram is as follows: figure 1 As shown, the selection of the power controller is th...
