Solar and LED combined to create new green energy

Today's world, oil, coal, natural gas and other major energy resource depletion are facing the danger, while also increasing environmental pressures, therefore, environmental protection, energy conservation has become worldwide industries to pursue. Solar energy is a clean, green energy, the semiconductor light-emitting diode led tube is an environmentally friendly, energy saving, high efficiency solid-state light source.
In the past 100 years, lighting has gone through three major stages: incandescent, fluorescent, HID lamps. Which is the first generation of incandescent light, fluorescent light is the second-generation, high-intensity gas discharge led light is the third-generation light sources (HID). Now in the lighting industry and has broad prospects for development of the LED light source is called the fourth-generation light source. Novel semiconductor LED as light source with a long life, high luminous efficiency, low power consumption, short startup time, solid structure and so on.
1 The principle of solar photovoltaic power generation:
Solar photovoltaic solar collector devices rely on the use of electronics properties of semiconductor materials, when the sunlight in the semiconductor PN junction, due to P-N junction barrier area had a strong built-in electrostatic field, resulting in potential base zone or non-equilibrium electrons and holes generated in the barrier outside the barrier region but spread into the non-equilibrium electrons and holes in the built-in electrostatic field under the effect of their movement in the opposite direction, leaving the barrier region , resulting in potential increased P region, N region potential drop, and so the outer circuit to generate voltage and current, the light energy into electrical energy. solar water heater photovoltaic power generation system can be divided into two categories, one is for power generation systems, and utility grid that is connected through a standard interface, like a small power plant; the other is stand-alone power generation system, which in their own the formation of closed circuit within the system. And power generation systems to the receiver through the photovoltaic array of solar radiation energy through conversion into a high-voltage high-frequency DC-DC, through the inverter and the inverter output to the grid after the grid voltage with frequency-phase sinusoidal AC current. The stand-alone photovoltaic power system will receive the first array to the solar radiation energy directly into electrical energy to the load, and the excess energy after a charge controller to chemical energy stored in batteries.
2.LED lighting advantages:
T10 LED Tube and have a long life, high luminous efficiency, small size, light weight, environmentally safe and reliable, there is a significant advantage is the LED turn-on voltage and line voltage, so without the use of ballast . This saves costs and energy consumption at the same time, greatly shortened the response time through power outages.
3 The combination of solar and LED lighting
Solar photovoltaic technology and LED lighting is the key to the perfect combination of both with the direct current, low voltage and can be matched. Therefore, the combination does not require the direct current generated by solar cells into alternating current, thus greatly improving the overall lighting system efficiency. Meanwhile, thanks to the use of grid technology or battery charge and discharge energy to make it more obvious advantages. With in-depth study of related technologies, LED lamp is increasing, ultra-high brightness of the LED will come out, is bound to replace general lighting power source, and significant energy savings and pollution-free.
