Introduction to the components of solar street lamps
1.Solar panels.
Solar panels for solar street light energy supply of components, the role is to the sun's light energy transform into electricity, transferred to stored in the battery, is the highest value in solar street light components. The primary use of solar cells is monocrystalline silicon. The solar photons and radiant heat are the ones that push and influence p-n junction holes and electrons in solar cells. This is what is commonly referred to as the photovoltaic effect principle. At present, the power of photoelectric conversion is about 13% to 15% of the photovoltaic cells, and 11% to 13% of polysilicon. Now the latest skills include photovoltaic thin-film batteries.
2. The battery
Battery is the power of the solar street light memory, the power supply will be collected lights to complete the lighting, because of the solar photovoltaic power generation system input energy is highly secure, so usually demand equipment battery system abilities. There are usually lead-acid batteries, ni-cd batteries, ni-h batteries. Battery capacity selection is usually follow the following principles: first, to the satisfaction of the lighting at night under the premise of the daytime the solar cell component of energy storage down as far as possible, also can be stored with satisfaction after rainy night lighting demand of electricity. The battery capacity is too small to be satisfied with the demand of the night lighting, the battery is too large, on the one hand, the battery has been in the loss of electricity, affecting the number of battery life, together form the waste. The battery should be matched with the solar cell and the electric load (street lamp). A shorthand method can be used to determine the relationship between them. The power of solar cells is more than four times higher than the load power, and the system is capable of normal operation. The voltage of the solar cell should exceed the operating voltage of the battery by 20~30%, and the ability to ensure the normal negative power of the battery. The storage capacity of the battery is more than 6 times higher than the daily load.
Control the inverter.
The existence of solar controller, its function directly affects the system longevity, especially the battery life. Control for industrial-grade MCU family control device, through measurement of environmental temperature, the battery and solar battery components inspection criterion parameters such as voltage, current, manipulation of the MOSFET device registration and shut off, to achieve a variety of control and protection functions.
4. LED light source
Solar street lamps light source is chosen whether can normal use the main goal of the solar lamps and lanterns, solar lamps and lanterns chooses usually suit low sodium lamp, energy-saving lamps, energy-saving lamps, LED light source, some use high power LED light source.
5. Lamp holder.
Lamp posts support LED street lamps.
1.太阳能电池板
太阳能电池板为太阳能路灯供应能量的部件，其作用是将太阳的光能变换为电能，传送到蓄电池中存储起来，是太阳能路灯中价值最高的部件。太阳能电池首要运用单晶硅为材料。在太阳能电池中推动和影响P-N结空穴和电子运动的是太阳光子和光辐射热。也即是通常所说的光生伏特效应原理。现在光电变换的功率，大约是光伏电池功率大约是单晶硅13%-15%，多晶硅11%-13%。现在最新的技能还包含光伏薄膜电池。
2.蓄电池
蓄电池是太阳能路灯的动力存储器，将搜集的电源供应路灯来完成照明，因为太阳能光伏发电体系的输入能量极不安稳，所以通常需求装备蓄电池体系才干作业。通常有铅酸蓄电池、Ni-Cd蓄电池、Ni-H蓄电池。蓄电池容量的挑选通常要遵从以下准则：首先在能满意夜晚照明的前提下，把白日太阳能电池组件的能量尽量存储下来，一起还要可以存储满意接连阴雨天夜晚照明需求的电能。蓄电池容量过小不可以满意夜晚照明的需求，蓄电池过大，一方面蓄电池一直处在亏电状况，影响蓄电池寿数，一起形成糟蹋。蓄电池应与太阳能电池、用电负荷 (路灯)相匹配。可用一种简略办法断定它们之间的关系。太阳能电池功率有必要比负载功率高出4倍以上，体系才干正常作业。太阳能电池的电压要超越蓄电池的作业电压20~30%，才干确保给蓄电池正常负电。蓄电池容量有必要比负载日耗量高6倍以上为宜。
3.操控逆变器
太阳能操控器的存在，其功用直接影响到体系寿数，特别是蓄电池的寿数。操控器用工业级MCU做主操控器，经过对环境温度的丈量，对蓄电池和太阳能电池组件电压、电流等参数的检查判别，操控MOSFET器材的注册和关断，达到各种操控和保护功用。
4.LED光源
太阳能路灯选用何种光源是太阳能灯具是否能正常运用的主要目标，通常太阳能灯具选用低压节能灯、低压钠灯、无极灯、LED光源，有些选用大功率LED光源。
5.灯杆灯架
路灯灯杆装置支持LED路灯。
