Do you know about solar garden light

Courtyard lamp need years of open, also need to open in the evening, but it does not have to use, some people worry about all the year round use garden light electricity cost will be very high, so he will choose solar garden light. Now also many, the kinds of solar garden light

 courtyard lamp need long open, also need to open in the evening, but it does not have to use, some people worry about all the year round use garden light electricity cost will be very high, she will choose solar garden light Solar garden light with solar radiation for energy, using solar panels to the battery during the day and night use battery to power a courtyard light source, without complex and expensive pipeline laid, can be arbitrary adjust the layout of the lamps and lanterns, safety and energy saving pollution-free, charging and the on/off process adopts intelligent control, electric automatic switch, without manual operation, stable and reliable work, saving electricity, maintenance free. 】 。 At present there are also the kinds of solar garden light, to see the solar garden lamp advantages and how to choose and guidelines. The advantages, solar garden light, the light health 1 no ultraviolet and infrared light, not prone to radiation ( Ordinary light line contains ultraviolet and infrared light) 2, long life, semiconductor chips, no filament, no glass bulb, not afraid of vibration, also won't soon broken, service life can reach fifty thousand hours ( The service life of the ordinary incandescent lamp only one thousand hours, the service life of the ordinary energy-saving lamps, only eight thousand hours) 3, green environmental protection does not contain harmful elements such as mercury and xenon, convenient recycling, and won't produce electromagnetic interference ( Ordinary lamp contains the elements, such as mercury and lead in electronic ballast of energy-saving lamps 【 Electronic ballast, 电子镇流器) , is one of the ballast, it is to point to use electronic technology to drive electric light source, to produce the required lighting electrical equipment. 】 Will produce electromagnetic interference) 4, high light efficiency 90% of its electricity into visible light, Ordinary incandescent bulbs 80% of electrical energy into heat energy, only 20% of the electric energy into light energy) 5, protect eyesight dc drive, no stroboscopic ( Ordinary light is ac drives, is bound to produce stroboscopic) 6, safety coefficient of the required voltage, electric current is small, heat is small, it is not easy to produce safe hidden trouble, can be used in the mines and other dangerous places. Second, solar garden light notes on how to choose and buy 1, solar panels, 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Solar panels, the main function in convert light energy into electrical energy, this phenomenon is called photovoltaic effect. In numerous solar photovoltaic cells more widely and more practical [mainly monocrystalline silicon solar cells Monocrystalline silicon solar cells, and is of high purity silicon rods for raw materials of solar cells, and is the fastest development of a solar cell. 】 , its price than monocrystalline silicon Silicon single crystal. 】 A lot cheaper batteries, conversion efficiency has in recent years also unceasingly to enhance. In rainy day more abundant than sunny southern region, using monocrystalline silicon solar cells as well, because of monocrystalline silicon solar cell performance parameters is stable. The amorphous silicon solar cell' Photovoltaic industry of solar cells are divided into crystalline silicon solar cells and amorphous silicon solar cells. 】 Better under the condition of the indoor sunshine is very weak, because the amorphous silicon solar battery low demands on the sun light conditions.
