Light-emitting diode (LED) street lamp lighting system capable of achieving barrier-free charging

Abstract

The invention relates to a light-emitting diode (LED) street lamp lighting system capable of achieving barrier-free charging. The LED street lamp lighting system comprises an LED lamp tube, a digital signal processor (DSP) control chip, a wind velocity detector, a sunlight intensity detector, charge equipment and a lead-acid storage battery, wherein the charge equipment charges the lead-acid storage battery; the charged lead-acid storage battery provides electric power supply to the DSP control chip, the wind velocity detector, the sunlight intensity detector and the LED lamp tube; and the DSP control chip is respectively connected with the wind velocity detector and the sunlight intensity detector, and controls the charge equipment to charge the lead-acid storage battery according to the detection results of the wind velocity detector and the sunlight intensity detector. Through the LED street lamp lighting system, different charge modes can be selected to charge an LED street lamp according to the environment change; and the condition of insufficient power supply for the LED street lamp is avoided.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED street lighting system with barrier-free charging. Background technique [0002] At present, the failure rate of LED street lights is less than 1% when used for more than 6000 hours. Lighting accounts for about 19% of the world's electricity consumption. If the efficiency of the lighting system adopted globally is doubled, it can be said to be equivalent to removing half of Europe's electricity consumption and heat dissipation. It can be seen that how to improve the energy-saving level of LED street lamps is very important for energy-saving and emission-reduction of global energy. [0003] In the prior art, energy-saving LED street lamps are mainly solar-powered street lamps. When solar energy is sufficient, solar energy is collected and converted into electrical energy and stored in batteries for use in LED street lamp lighting. To a certain extent, it meets the energy-savin...

Problems solved by technology

[0003] In the prior art, energy-saving LED street lamps are mainly solar-powered street lamps. When solar energy is sufficient, solar energy is collected and converted into electric energy and stored in batteries for use in LED street lamp lighting. To a certain extent, it meets the energy-saving requirements of LED street lamps, but it cannot be applied in areas where solar energy is insufficient. At the same time, there is no technical solution for using wind energy power supply for LED street lamps in the prior art. There is still room for improvement in the power supply circuit of the existing LED street lamps.
