Modern municipal solar roadway lighting demands precise photometric distribution and strict thermal management. Unlike standard symmetric flood fixtures, municipal roadway projects require asymmetric batwing distribution (typically 80°×160°) to achieve broad, uniform illuminance across multiple lanes without causing high-angle glare for motorists.
The Role of Precision Optical Batwing Distribution
By utilizing optical-grade Teijin polycarbonate batwing lenses, light is directed across the roadway axis (C90/270) while controlling the longitudinal spread (C0/180). This optical efficiency allows greater pole spacing—often 25 to 35 meters—thereby reducing total luminaire counts, civil foundation costs, and installation labor for municipal authorities.
Thermal Isolation and LiFePO4 Cell Protection
Ambient temperatures in desert, tropical, and sub-tropical deployment zones regularly exceed +45°C. When combined with internal LED operating heat, unisolated battery compartments can reach critical degradation temperatures. Linqiu Science addresses this with physical dual-chamber isolation: the high-temperature LED heat sink is thermally separated from the lower battery and BMS chamber. This architecture preserves battery cycle life beyond 6,000 cycles and ensures stable all-night discharge.
