Understanding of solar energy lawn lamp parts together

A set of perfect system of solar energy lawn lamp contains: light source, control device, battery, solar energy battery components and light body. When the day the sun in the solar cells, solar cells to turn light energy into electrical energy and through control circuit to electricity

   a set of intact solar energy lawn lamp' Lawn lamp design mainly exterior and downy lamplight add security for urban green space landscape and beautiful, and generally has the characteristic such as easy installation, adornment sex is strong, can be used for park, garden villas, square, greening, greening of the place such as decorative lighting. 】 System includes: light source, control device, battery, solar battery components 【 Solar energy battery components is of high efficiency crystalline silicon solar cell lines of toughened glass, super white cloth, EVA, transparent TPT backboard and the composition of aluminum alloy frame. 】 And the light body. When the day the sun in the solar cell' Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 , the solar cell to turn light energy into electrical energy and through control circuit to electrical energy stored in the battery. After dawn, and power in a battery by control circuit for lawn lamp LED light source power supply. The next morning at daybreak, battery to suspend the lighting power supply, lawn lamp, solar battery for battery charging, cycle, cycle operation. Manipulation of the device is composed of MCU, sensors, through optical signal collection and discriminant part manipulation of light source on and off. The lamp body first and the decoration of the effect of system protection, ensure the normal working of the system. In the light source, control device, battery is the key of the resolution lawn lamp system function. Solar cells that convert solar energy into electricity, is useful have monocrystalline silicon 【 Silicon single crystal. 】 , polycrystalline silicon and amorphous silicon 【 非晶硅α- Si is also called the amorphous silicon. 】 Three kinds of solar cells. Monocrystalline silicon solar cell' 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. 】 Function parameter is stable, more suitable for rainy day, the sun is not very enough south area utilization. Polycrystalline silicon solar cell' Polycrystalline silicon solar cells, monocrystalline cells with high conversion efficiency and long life and material preparation technology of amorphous silicon thin-film batteries relative to simplify the advantages of a new generation of battery, its conversion efficiency of 17 - general 18%, slightly lower than that of single crystal silicon solar cell, there is no obvious efficiency decline, and possibly on the cheap substrate material preparation, the cost is far lower than the single crystal silicon battery, and efficiency higher than that of amorphous silicon thin-film batteries. 】 Relatively brief production technology, low price than monocrystalline silicon, suitable for eastern and western area in the sun, sunshine is good enough to use. The amorphous silicon solar cells Photovoltaic industry of solar cells are divided into crystalline silicon solar cells and amorphous silicon solar cells. 】 Requirements for the sun light conditions is lower, is suitable for the local use in the outdoor sunlight lack. Solar cells work voltage of battery voltage of 1. 5 times, talents to ensure to normal battery charging. Such as to 3. 6 v battery' Battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery. 】 With 4 charging demand. 0 ~ 5. 4 v solar cells; To 6 v battery charging demand with 8 ~ 9 v solar cells; To the 12 v battery' Battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery. 】 With 15 ~ 18 v solar batteries charging demand.
