Intelligent solar micro-computerized soft-drive constant-current source controller

Abstract

The invention relates to the field of solar application technologies and discloses an intelligent solar micro-computerized soft-drive constant-current source controller. The intelligent solar micro-computerized soft-drive constant-current source controller comprises a shell which is highly waterproof, dampproof and corrosion-resistant. A circuit board in the shell is provided with an optical recognition circuit and is connected with an input end of a storage battery charging circuit and a solar panel respectively, and an output end of the storage battery charging circuit is connected with a voltage stabilizing circuit; the optical recognition circuit is connected with a charging switch control circuit of the storage battery charging circuit through an MCU (micro control unit); and the MCU is connected with a direct-current street lamp through a direct-current street lamp soft-drive constant-current source circuit, and the direct-current street lamp is connected with the MCU through a direct-current street lamp brightness control circuit. The intelligent solar micro-computerized soft-drive constant-current source controller has the functions of protection against storage battery overcharge, overdischarge, overload and short-circuit, intelligent constant-current control of operation time of full power and half power of the direct-current street lamp and high water proofing, damp proofing and corrosion resistance, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of controllers used in solar street lamps, tunnel lamps and garden lamps, in particular to a solar microcomputer intelligent soft drive constant current source controller. Background technique [0002] At present, there are many controllers for solar street lights, tunnel lights, garden lights, and advertising lights on the market. There are several problems in use: [0003] 1) The control time is not standard, and the lights cannot be turned off on time. Sometimes it is fully bright day and night, causing the LED lights to age quickly and the battery to age severely. [0004] 2) The light control is not standard. Sometimes the light turns on when the sun goes down, sometimes it turns on when it is cloudy, and sometimes the vehicle lights and other lights turn on and turn on and off. [0005] 3) It is not waterproof, moisture-proof, or corrosion-proof. After a few months of use...

AI Technical Summary

Problems solved by technology

[0006] 4) Some are perfused with branch glue and other chemical materials, which have poor heat dissipation and are disposable products, which cannot be repaired if they are broken, resulting in large economic losses

[0007] 5) The charging performance is not good, sometimes charging is not charging, some are direct charging, there is no overcharge and overdischarge protection, the battery is broken faster, and the effective use is relatively low

[0008] 6) There is no half-power function, and it is bright all night, which will cause a large loss of battery and rapid aging of LED lamp beads

[0009] 7) The heat dissipation effect is poor, and the parts are easily damaged, especially the rectifier diodes, board bridges, and field effect high-power tubes are easy to burn out

[0010] 8), LED lights, the power can not reach, must add a constant current source, there is no independent controller constant current source
