Product Brief Introduction
Definition of All-in-one LiFePO4 Solar Street Light
Integrated LiFePO4 solar street light is a highly integrated outdoor lighting fixture that encapsulates monocrystalline silicon photovoltaic panel, high-efficiency SMD LED light source, intelligent MCU control module, PIR human induction sensor and built-in lithium iron phosphate battery inside die-cast aluminum lamp housing. Different from split-type traditional solar street lights with separated solar panel, battery box and lamp body, this integrated structural design cancels external wiring, embedded wiring slots and independent buried battery container, realizing streamlined modular production and on-site rapid installation.
Core Product Positioning
Target application groups cover international municipal engineering contractors, rural road upgrading project investors, industrial park developers, farm operators and villa community property managers. The product is oriented to medium and large-scale outdoor fixed lighting projects without stable municipal power grid access, filling the market gap of low maintenance cost, zero post-operation electricity consumption and all-weather adaptable outdoor road lighting equipment.
Basic Rated Parameter Overview
Serial specifications cover multi-power modules with corresponding lumen output ranging from 6000LM to 25000LM, configured with matched-capacity LiFePO4 batteries and graded high-conversion monocrystalline silicon panels, complying with IEC62471 photobiological safety standard and IP65 international waterproof and dustproof grade, which meets mainstream certification requirements for cross-border export and global engineering tender procurement standards.
Core Reasons for Being Preferred in Rural Road and Engineering Lighting Projects
Adaptability to Rural Infrastructure Construction Pain Points
Most rural scattered villages and remote country lanes lack complete low-voltage power distribution network. Conventional AC-powered street lighting needs trench excavation, cable purchase, transformer erection and regular circuit maintenance, which occupies over 60% of the total project investment. LiFePO4 integrated solar street light relies entirely on photovoltaic self-power generation without grid access, saving construction cost of power distribution auxiliary facilities from source.
Rural branch roads, farm connecting roads and village inner lanes feature irregular distribution and dispersed layout. Integrated solar street lamp realizes single-point independent power supply without series-parallel circuit connection, flexible to arrange installation spacing according to actual road width and pedestrian flow, avoiding layout restriction brought by fixed power supply nodes.
Outstanding Comprehensive Cost Advantage for Medium-to-Large Engineering Projects
After one-time installation completion, the whole lighting system absorbs solar radiation for power storage and lighting operation, no monthly grid electricity fee generation, effectively cutting long-term operating budget for government rural renovation projects and commercial park engineering projects.
LiFePO4 battery and SMD LED light source both own ultra-long service life, the whole lamp reduces component replacement frequency significantly compared with lead-acid battery split solar lamps and traditional sodium lamps, lowering post-project after-sales maintenance labor and accessory replacement expenditure for engineering purchasers.
Strong Environmental Adaptability for Complex Outdoor Engineering Environment
Rural and field engineering sites face drastic temperature fluctuation, rainy weather, dust erosion and humid coastal climate. Die-cast aluminum shell plus fully sealed IP65 structural design effectively isolates rainwater, sand and moisture; wide-temperature LiFePO4 battery works stably under ambient temperature ranging from -30℃ to +60℃, avoiding sudden lighting failure caused by extreme high or low temperature in field engineering environment.
Core Technologies of LiFePO4 Battery Integrated Solar Street Light
LiFePO4 Energy Storage Battery Core Technology
The built-in lithium iron phosphate cathode material adopts high-purity nano-level lithium iron phosphate powder synthesis technology, realizing more than 3000 times deep charge and discharge cycles under standard 0.2C charging and discharging rate, far exceeding 300–500 cycle life of conventional ternary lithium battery and 300–800 cycles of lead-acid storage battery. Low self-discharge rate is controlled below 3% per month, ensuring battery capacity reservation during continuous overcast days.
Independent built-in BMS battery management chip monitors real-time single cell voltage, charging current and internal temperature of battery pack, activating overcharge protection, over-discharge protection, short-circuit protection and over-temperature protection automatically. BMS matches MCU master control system to adjust daytime charging current according to sunlight intensity, preventing irreversible damage to battery caused by overcharging under strong sunlight.
High-efficiency LED Light Source & Secondary Optical Distribution Technology
The lamp source adopts copper substrate packaged high-power SMD2835 LED chips with low thermal resistance structure, effectively deriving heat generated during continuous lighting to restrain luminous decay; the product's overall luminous efficacy reaches 180LM/W, CRI＞75, fixed color temperature at 6500K neutral cool white, conforming to international road lighting color rendering specification. After 5000 hours of continuous aging test, lumen attenuation is controlled within 3% of initial brightness.
Customized high-transmittance PMMA optical lens carries out secondary light distribution for LED outgoing beam, setting fixed 120° wide flood lighting angle, eliminating central over-glare and pavement dark area problems of unassisted bare lamp bead lighting, improving effective pavement illumination area and road night driving safety coefficient.
Photovoltaic Power Generation & Intelligent Control System Technology
Front panel uses tempered glass covered monocrystalline silicon solar cell with photoelectric conversion efficiency up to 22%, superior to conventional polycrystalline silicon panel with 16%–18% conversion rate. Under AM1.5 standard test condition, 6–8 hours of effective daytime sunlight can fully replenish rated battery capacity; surface silica gel full sealing process prevents panel from aging and power efficiency reduction caused by rainwater infiltration.
Integrated photosensitive dusk-dawn sensor, PIR human body infrared motion sensor and programmable remote control chip form triple intelligent control logic. Photosensitive component automatically identifies ambient illuminance value to trigger dusk-on and dawn-off switch; PIR sensor switches lamp from low-power standby brightness to full rated brightness once human or vehicle movement is captured; remote controller supports 3H/6H/8H fixed timing setup to meet customized engineering lighting demands.
