In addition to the advantages of long service life, high luminous power, small size, light weight, environmental protection, safety and reliability, LED semiconductor lighting sources, there is another obvious advantage that is because the LED start voltage and working voltage do not match, so there is no need to use a ballast. In this way, while saving cost and energy consumption, it also greatly extends the response time of power on and off.
The key to the perfect combination of solar photovoltaic power generation technology and LED lighting is that the two are both direct current, low voltage, and can be matched with each other. Therefore, the combination of the two does not need to convert the direct current generated by the solar cell into alternating current, which greatly increases the power of the entire lighting chip. At the same time, with the help of grid-connected technology or the use of battery charging and discharging energy, the downwind is more distinct. Following the in-depth study of related technologies, the luminous power of LEDs is advancing from time to time, and ultra-high brightness LEDs will soon be available, which will inevitably replace general lighting electric light sources, and a few waste power and no purification. Because the working current of LED is DC, and working voltage is low. Solar cells convert light energy into direct current electricity, and solar cell components can be combined in series and parallel to lose the voltage required for practice. These features match exactly with LEDs. The combination of the two will achieve high power utilization rate, high safety function and reliability, end energy-saving, environmental protection, safety, and high-efficiency lighting shavings, and end a very complete combination.
