Energy-storage type solar energy LED lamp

Abstract

The invention discloses an energy storage type solar LED lamp. The invention comprises a solar battery panel, a storage battery, a LED load and controller, wherein, the controller comprises a system detecting circuit, a state detecting circuit, a storage battery voltage detecting circuit, a clock controller, and a pulse adjusting circuit; the controller can automatically adjust the output impulse frequency through the pulse adjusting circuit, and adjust the output power through testing the capability of the storage battery and according to the capability of the storage battery,, thus the LED lamp has high efficiency and outstanding energy saving effect when the LED lamp is operated under perfect pulse condition. The energy storage type solar LED lamp of the invention has the advantages of environmental protection, safety, easy installation, good application effect, and small maintaining quantity, thus the invention can be widely applied to the lighting in the street and the courtyard.

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...

Problems solved by technology

[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 by the LED lamp cannot automatically change with the battery capacity.

In the case of a certain capacity, it is difficult to meet the long-term lighting, and the range of use is affected

The conventional solar LED street light controller adopts constant current source control, its efficiency is about 80%, and its luminous efficiency is low, and because the LED lamp beads work in a constant current state for a long time, the brightness of the LED lamp beads has a large attenuation, which affects the LED lamp bead. The service life of the lamp causes an increase in the cost of use, and lacks market competitiveness in terms of cost performance
