Touch Control Type Hybrid Energy Storage Solar Led Lighting System

With the depletion of non-renewable energy such as gas and oil, thus the energycrisis caused by global issues are increasingly grim, according to statistics, the globallighting electricity consumption accounts for about22%of the whole society,therefore, to reduce electricity for lighting energy savings one of the most effectiveway. Solar energy as a new type of green energy, inexhaustible, non-polluting moreand more attention has been paid; super capacitor is a new energy storage devices,both the power density of conventional capacitors, rechargeable battery powerdensity advantages of rapid charge and discharge and long life, excellent energystorage advantage to come out after the show; LED as a third-generation lightingtechnology, energy saving, environmental protection, safe and reliable, so ifcombined with the advantages of the three respective in energy efficiency will play amajor role.Stand-alone hybrid energy storage PV power LED lighting systems for thestudy, only UC3909battery management chip, through the adaptive PI algorithm,combined with the51MCU Hop Thai touch microcontroller, the use of hybridenergy storage technology to improve the utilization of the system,extend battery life,while taking advantage of the super capacitor voltage characteristics and boostcircuit to improve low-light ability to charge. Through theoretical analysis,parameter calculation, experimental testing and data processing. The main contents1.Combined with solar cell output characteristics, the need for maximum poweroutput (MPPT); the experimental design of the maximum power point trackingmodule, to improve the utilization of solar cells.2.The characteristics of super capacitors and batteries, with their respectiveadvantages, analysis of the advantages of hybrid energy storage; the experimentalusing super capacitors features achieve low-light charge.3.Touch LED lighting dimming system; experimental design a11touch key panel,making the whole system more humane.4.PWM dimming and analog dimming LED color temperature, illumination and color rendering index; experiment by testing and data analysis of the differentdimming LED color temperature and light effects, and color temperature brightnesscan be adjusted.
