Stars LED Blue beacon light, rotating beacon light, solar power beacon light

Solar power beacon light in the choice of introduction In the design of solar lighting lamp, relates to a light source, solar cell system, battery charge and discharge control and many other factors, including any link problems will cause the product defect. solar barricade lights nergy lamp is composed of five parts: solar panel, controller, storage battery charging and discharging, the load and the lamp shell. 1 solar cell For polycrystalline silicon solar cell production process is relatively simple, low prices than single crystal, conversion efficiency increased. More in rainy days, the sun is not very abundant in southern area, using rotating beacon light 12v  crystal silicon solar cell as well, because of monocrystalline silicon solar battery performance relatively stable. The amorphous silicon solar cell in the indoor sunlight is weak situation is better, because the amorphous silicon solar cells to solar illumination conditions require relatively low. First of all, any one of solar power beacon light products, we must first understand the solar battery, solar battery has five major electrical parameters, namely: the short-circuit current, open circuit voltage, peak current, peak voltage, peak power. For the general customers, how can we know its 5 parameter values? For the general customers, how can we know its 5 parameter values? Teach you a simple method, let us know that the relative parameters, we can at 12 noon sunlight conditions with universal testing the 5 parameter meter (of course that the measured values can be a bit error). For a single solar cell, it is a PN junction, except when the sunlight above, it can generate electricity, it also has all the characteristics of solar power beacon light. In the standard light conditions, the nominal output voltage of it. Solar cell components in the solar lighting use are composed of a plurality of solar battery connection. Solar cell components in the solar power beacon light  use are composed of a plurality of solar battery connection. The user can read to understand the stability of prices of solar cells, solar lamps lighting performance and. Below I will introduce the charge discharge controller, load, battery etc.. The 2 charge and discharge controller Regardless of the size of solar lamps, a good performance of the charging and discharging control circuit is essential. Regardless of the size of solar lamps, a good performance of the charging and discharging control circuit is essential. In order to prolong the service life of the battery, charge and discharge conditions on it must be limited, to prevent the battery from overcharge and deep discharge. In addition, since the input energy of solar photovoltaic power generation system is very unstable, control of photovoltaic power generation system for battery charging control than ordinary battery charging to more complex. For the design of solar lamps, success and failure is often depends upon the success and failure in the charging and discharging control circuit. Without a good performance of the charging and discharging control circuit, can not have a good performance of the solar lamp. Charge discharge controller must have the following characteristics, namely: anti charging control, prevent charging control, prevent over discharge control, temperature compensation. 3 battery Since the input energy solar power beacon light of photovoltaic power led blue beacon light  system is very unstable, so the general need to configure the battery system to work, solar lighting is no exception, you must configure the battery can work. General lead-acid battery, Ni-Cd battery, Ni-H battery, their capacity will directly influence the reliability of the system and the system of price. Battery capacity choice to follow the following principles: first, in can meet the night lighting under the premise of the daytime solar cell components, energy storage down as far as possible, but also can store meet continuous overcast and rainy day night lighting need electricity. Battery capacity is too small can not meet the need of the night lighting. Storage capacity is too large, the battery is always in the state power loss, affect the life of the battery, at the same time wasted.
