BOSUN All-In-One Solar Street Lights (BJ Series) – High-Efficiency Lighting for South America

BOSUN’s BJ Series all-in-one solar street lights integrate the LED fixture, solar panel, battery and controller into a single compact unit. Each model delivers up to ~150W of LED power using high-efficacy LED chips (~180 lm/W) and wide optics (70×150°) to meet roadway illumination standards. These self-contained lights run approximately 12 hours per night on a full charge, with no external wiring needed – greatly simplifying installation for municipal projects.

The housing is 100% die-cast aluminum (anti-rust and corrosion-resistant), ensuring durability even in harsh environments. A high-transmittance optical lens (>96%) focuses the light uniformly across streets and highways. Inside, premium Philips LED modules provide bright, uniform light. Thanks to its integrated design, the BOSUN all-in-one lamp requires only mounting and positioning – no trenching or wiring – which is especially attractive for government and engineering teams deploying large-scale road lighting.

Advanced Power Management and Smart Controls

At the core of the system is BOSUN’s patented Pro-Double MPPT solar charge controller. This dual-stage MPPT significantly boosts energy capture: it achieves about 99.5% MPPT tracking efficiency and ~97% conversion efficiency, yielding 40–50% higher charging efficiency than ordinary PWM controllers. In practice, this means more of each day’s solar energy is stored in the battery and less is wasted, lowering the system’s overall cost per lumen. The intelligent controller also includes protections (reverse-connection, overcharge, etc.) and extremely low standby current, and is rated IP67 waterproof for reliability.

IoT Connectivity and Intelligent Dimming

Each BOSUN light is “smart” ready. The MPPT controller offers an IoT interface (RS485/TTL), allowing remote monitoring and control when connected to a streetlight management platform. This lets engineers check lamp status or adjust settings without field visits. In addition, built-in sensors enable adaptive lighting modes. An infrared motion sensor keeps the light at ~30% output when the street is empty, then automatically boosts to 100% brightness when movement is detected within ~8–10 meters. The controller’s programmable schedule (up to five time periods) and “morning light” features let operators set full output during peak hours and dim down later at night. These smart controls maximize energy savings and extend battery runtime while ensuring safety.

High-Efficiency LED and Weatherproof Design

BOSUN lights use high-brightness LED chips and precision optics for maximum luminous efficiency. The optical lens is designed for >96% light transmission, and its asymmetric beam pattern (70°×150°) spreads light uniformly across roads. The lamp body is made of thick, die-cast aluminum alloy, providing ultra-strong anti-corrosion protection. 100% die-casting means the fixture “will not rust even if installed by the sea.” This robust housing and high-quality optics ensure consistent brightness and long life even under intense sun, humidity or dust. Combined with the advanced LEDs, the BOSUN BJ series meets rigorous roadway standards for brightness and uniformity while resisting environmental wear.

Long-Life Battery and All-Climate Endurance

For energy storage, BOSUN uses new LiFePO₄ battery cells with full 6000 mAh capacity and a built-in Battery Management System (BMS). The BMS provides over-current, short-circuit and thermal protection, plus charge balancing, so the battery is safe and maintained at peak condition. Unlike competitor lights that may use recycled cells without protection, BOSUN’s batteries are high-quality and well-managed. LiFePO₄ chemistry is inherently stable and heat-resistant, and with the controller’s temperature compensation, each light can operate reliably in extreme climates. In practice, this means the lights keep running in very hot or cold environments, making them suitable for diverse South American settings.

Benefits for South American Municipal and Infrastructure Projects

• Easy Installation & Reliability: No trenching or wiring is required. Each all-in-one fixture is quickly pole-mounted and immediately functional. Once installed, it runs autonomously on solar energy.
• High Efficiency & Cost Savings: The combination of 180 lm/W LEDs, Pro-Double MPPT and smart controls maximizes output per watt. Municipalities benefit from zero electricity bills and reduced maintenance expense.
• Durable, Low-Maintenance Design: Thick aluminum housing and sealed optics protect against corrosion, dust and water. The advanced LiFePO₄ battery with BMS prevents overdischarge and thermal issues, greatly extending service life.
• Smart Operation: Integrated motion sensors and programmable dimming reduce energy use after midnight, while IoT-enabled controllers allow centralized monitoring of large installations.
• Proven Track Record: BOSUN has supplied tens of thousands of solar street lights to projects worldwide, including installations in Brazil and other South American countries.
• Sustainability & Public Image: Using solar lights helps meet environmental targets by slashing carbon emissions. The clean, quiet operation of BOSUN’s off-grid lights also improves community safety and corporate green credentials.

BOSUN even offers free DIALux lighting design services to help planners optimize illumination layouts for each project. In summary, BOSUN’s all-in-one solar street lights (BJ Series) deliver bright, reliable, and sustainable lighting for roads, highways and public spaces in South America, while minimizing life-cycle cost and maintenance for governments and contractors.
