Solar LED lamp made in Jiaojiang

The evening of July 6th, the world drizzle, I came to the Jiaojiang District pepper group, all 3 of the plant using solar LED (semiconductor light-emitting diode) of the street lamp, according to the whole plant as day.

According to jiaoguang Group Chairman Zhu Jiemin introduced the 3 lamp power of 80 watts, 400 watts of high-pressure sodium lamp brightness is equivalent to now on the road to use, due to the use of solar energy, not a penny of the cost of energy consumption. It is estimated that if the use of the 3 street lamps are 400W high pressure sodium lamp, to consume more than 2 thousand and 600 kwh of electricity per year, and the cost of nearly $2000, and for the use of solar energy LED emissions of carbon dioxide per year after more than 2 thousand and 41 kg. The completion of the solar project started to promote energy saving and emission reduction in Jiaojiang, low-carbon economic development of green road has a model significance.

Solar energy as a renewable energy, and gradually replace some of the city's production and living of conventional energy is the trend. LED lighting is a new generation of solid-state lighting source internationally recognized, has the advantages of energy saving, high efficiency, long life, green environmental protection, no radiation and other notable features, its power consumption is only 1/10 of incandescent lamp, fluorescent lamp 1/3, life is 100 thousand hours, ordinary incandescent lamp life is 50 times, 20 times of fluorescence the life of the lamp, it is the fourth generation lighting products following the incandescent lamp, fluorescent lamp, gas discharge lamp.

"This solar panel can reach 115 watts. Zhu Jiemin pointed out that the company has just developed a size of 120 cm x 80 cm solar panel said. The solar panel day cumulative power can drive 80 watts of power LED (light emitting diode) lighting the 5 night, a record 17 night, the light remains bright, solve the solar lighting problem, cloudy, winter snow and other inclement weather conditions.

In the exhibition room, the solar LED lamp is composed of solar panel, control box, maintenance free battery, constant current driver, LED lamp and road lamp post. The working principle is the use of solar panels, photovoltaic effect made of solar radiation and into electrical energy output, through the charging and discharging controller is stored in the accumulator, the night when the light intensity is reduced, the battery in the open circuit voltage of about 4.5V, the battery on the discharge lamp head start.

Now, the most critical is the problem of solar power grid. Zhu Jiemin hope that the government introduced the relevant policies as soon as possible to solve the solar home bottleneck problem. It is reported that, in general, the solar power generated to DC, if incorporated into the grid, through a series of procedures, one of the most critical, is to use the converter to the radiation of the sun into DC, then converting the direct current into alternating current through the device, then change the input voltage of power grid.

How does the voltage change? How to calculate the price after transmission to the grid? How much government subsidies? At present, these problems need to be studied.
