Lithium ion LED street lamp power energy is solar panels, is one of the important parts of LED street light. LED street lamp which is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, the LED street lamp will become the choice of road lighting energy saving transformation. During the day, sunlight on solar panels convert light energy into electrical energy and store it in the lithium battery, and then stored in the lithium battery. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, the LED street lamp will become the choice of road lighting energy saving transformation. The lights in the night for the LED light source power battery. Below, analysis of lithium battery led lights led lights technician for you key protected mode:
mode 1. Direct charging protection point voltage:
direct charge also called quick charge. This is a quick charge. When the lithium battery voltage is low, usually with large current and relative Gaodianya battery to lithium battery. However, there is a control point, also known as protection. Direct charge protection point voltage is commonly & other; Super protection point & throughout; Voltage. Charging, the voltage of the lithium battery cannot be higher than the guard point, otherwise it will cause charging too much, bad for lithium batteries.
mode II, floating charge voltage control points:
usually, upon the completion of the equilibrium, the lithium battery can also stand for a period of time, make its voltage of natural decline. When it down to maintain point voltage, it into a floating state. Similar to small current charging, low battery voltage. In low fill, to fill it, then in series in order to avoid the battery temperature rising, this is very favorable for lithium batteries.
mode 3. Homogeneous charge voltage control points:
directly after charging, lithium batteries will generally by charging and discharging controller for a period of time, make its natural voltage drops. When it fell to & other; Recovery voltage & throughout; Value, it will enter a state of uniform charge. Charging at the same time, i. e. , & other; Balance charging & throughout; 。 Filling time shoulds not be too long, generally a few minutes to ten minutes, long time setting and harmful. For a small system with two lithium batteries, both are not important. So. Led street light controller is generally not fully charged, only two phases.
pattern 4 and over discharge protection termination voltage:
lithium battery discharge should not be lower than the national standard. Although the lithium battery manufacturers have their own protection parameters, but they must be more close to the national standard.
to be on the safe side, 12 v lithium-ion battery over discharge protection point voltage usually add 0. 3 v as the zero drift correction of temperature compensation and control circuit, makes the 12 v battery over discharge protection point voltage is 11. 10 v, 24 v system GE discharge protection point voltage is 22. 20 v.
the LED street lamp manufacturers of LED street lamp is equipped with intelligent control system, can prevent the overcharge and over discharge, greatly reduce maintenance difficulty, effectively extending the service life of the battery.
