A lithium ion LED street lamp principle of work

by:SUNFREE     2021-02-10
The present invention USES sunlight as an energy source for lithium battery charger, solar panels during the day for lithium battery, save cost, installation is more simple, more convenient structure. 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 light will become the best choice of the road lighting energy saving reconstruction. Lithium electricity LED street lamp is powered by crystalline silicon solar panels, using lithium batteries and maintenance-free ( The ternary material or iron phosphate) Electricity saving, with ultra high brightness LED lamp as light source, street lamp intelligent charging and discharging controller controlled. 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 light will become the best choice of the road lighting energy saving reconstruction. It is used to instead of the traditional public power lighting. Without laying cable without ac power without charge; Dc power supply, photosensitive control; Good stability, long life, high luminous efficiency, simple installation and maintenance, safety performance is high, the energy conservation and environmental protection, economic and practical. The advantage of me. Can be widely used in urban primary and secondary trunk road, residential areas, factories, tourist attractions, parks and other places. Product parts structure of lamps and lanterns: light pole and steel bracket, surface spraying of plastic processing, panel connection and patented anti-theft screw. System of lithium power LED Light emitting diode) Street lamp system can work 365 days! The system includes lamp ( Including stent) , LED lamp holder, lithium electricity LED ( Light emitting diode) The special controller, lithium batteries of the street lamp ( Including lithium battery pack) And so on. Solar energy battery components typically use monocrystalline silicon or polycrystalline silicon solar cell components; LED lamp holder generally use high power LED light source; Controller is usually placed in the lithium battery aluminum box, with photo, time control, overcharge, discharge protection and reverse connect protection function, there are four seasons controller adjust the lighting time half power function, intelligent charging and discharging function, etc. ; Lithium-ion batteries are usually on the back of the panels. Solar lamps and lanterns is automatic work, instead of rewiring digging groove, and the need to install the rod in the embedded parts ( Concrete base) On. LED light source _ high luminous efficiency, low power consumption, long service life, low working temperature. 2. Safe and reliable. , small volume and high response speed, environment friendly. Under the same brightness, incandescent lamp power consumption is 1/10 of the incandescent lamp, fluorescent lamp of a third, but the life is 50 times of incandescent lamp and fluorescent lamp 20 times. Is the incandescent lamp, fluorescent lamp, gas discharge lamp after the fourth generation of lighting products. 5. Application in high light LED application field of the market, the emergence of a single high power ultra bright LED is possible. It is one of the greatest invention after human invention incandescent bulbs. 1) battery components stent Angle design in order to make the solar tank receives the solar radiation as much as possible within a year, for the sun to select a best Angle. Discussion on the best Angle of the solar cell module has appeared in some academic journals. Street lamps use area of changsha area, the Angle of the solar cell module stents for selected 16 o.
