Abstract
Description
technical field
[0001] The invention relates to an illuminating lamp, in particular to an energy-storage solar LED lamp which uses a solar panel to charge a battery and automatically adjusts luminous power according to the capacity of the battery. Background technique
[0002] Solar lamps are widely used in garden decoration, road lighting, etc. because they do not need to erect wires or pre-embedded cables, are easy to install, and do not require electricity charges after installation. However, the current energy-saving solar lamps generally use constant current control. In this way, the controller cannot automatically detect the capacity of the battery and automatically adjust the light intensity according to the capacity. When the battery capacity is sufficient, it can work normally. When the capacity is insufficient, it will stop working when the battery is used up. Regardless of the capacity of the battery, the LED lamp works at the rated power, and the power consumed b...
