How to lay the courtyard lamp in the district?

Answer:

LED as a new type of lighting technology, with low power consumption, high luminous efficiency, good color, high reliability, small volume and light weight, energy saving and environmental protection, long life and other advantages, is the industry that is the main development direction of future lighting technology. As LED is a cold light source, the semiconductor lighting itself has no pollution to the environment, and compared with the incandescent lamp and fluorescent lamp, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of the ordinary incandescent lamp, and the 1/2 of the fluorescent lamp tube is very energy-saving.
1. AC power supply is 15% less efficient than solar energy, that is to say, to obtain the same output power, the AC power will be more than 15% of the input power. And the power factor, if not compensated, will lead to reactive power increase of the grid.2., the biggest advantage of solar LED street lights is that they don't have to pay the electricity bill at all. A 250 Watt High pressure sodium lamp costs about 766 yuan per year. 20 million street lamps, electricity, an expenditure is 15 billion 330 million yuan.3. ordinary high-pressure sodium lamp life is only 3000-5000 hours, and LED life of up to 30000-50000 hours, and with the progress of technology, LED life is likely to be as high as 100 thousand hours.
Solar LED courtyard lamp good manufacturers, or suggest you go to Huangchuan Limin technology, according to your configuration needs, one to one custom made a solar street lamp.
