• LED Information Screen for Publishing: Equipped with a 2.8-inch TFT-LCD screen (240×320 pixels, automatic brightness adjustment), supporting remote updates of images, text, and animations via RS485/WiFi communication, with a publishing delay ≤1 second. IP65 protection ensures suitability for outdoor environments.
• Infrared Human Body Induction: Pyroelectric sensor (RE200B) detects within 0-10 meters with a 120° horizontal viewing angle. It fully illuminates (50W) when people approach and delays dimming/off (10W) when people leave, achieving a measured energy-saving efficiency ≥50%. It resists electromagnetic interference and operates stably across wide temperatures.
• Solar Hybrid System: Monocrystalline silicon solar panel (50W, efficiency ≥22%) + 12V/20Ah lithium iron phosphate battery. With an average of 4 hours of daily sunlight, the self-power supply rate ≥70%, reducing grid power consumption by approximately 120 kWh annually, promoting low-carbon environmental protection.

Low Power Energy Saving

High-Efficiency LED Light Source

• The Solar LED 50W uses advanced LED chips with a luminous efficiency exceeding 160lm/W, saving over 37.5% energy compared to traditional 50W high-pressure sodium lamps (luminous efficiency ~100lm/W).
• Through optimized chip packaging and heat dissipation design, the LED operates stably at 50W with minimal light decay. Over 50,000 hours of operation, the luminous flux retention rate ≥70%, reducing long-term usage costs.

Smart Power Management System

• The luminaire features a built-in smart power driver with wide voltage input (AC85-265V) and constant current output, power factor ≥0.95, effectively reducing reactive power loss.
• Using PWM dimming technology, it precisely adjusts output power, which can be reduced to below 10W in low-brightness scenarios, further enhancing energy efficiency while avoiding flicker harm to human eyes, compliant with IEEE PAR1789 standards.

Solar Hybrid Power Supply

● Integrates high-efficiency solar panels, such as the monocrystalline silicon SolarEdge SE50K-W, with a photoelectric conversion efficiency ≥22% under standard test conditions (STC, irradiance 1000W/㎡, cell temperature 25℃).

● Paired with a 12V/20Ah lithium iron phosphate battery, it charges during the day and powers at night, enabling intelligent switching between grid and solar power. In areas with an average of 4 hours of daily sunlight, the solar self-power supply rate ≥70%, reducing annual grid power consumption by ~120 kWh and significantly lowering operational costs and carbon emissions.

Technology of LED Information Screen for Publishing

Screen Hardware Configuration

The Solar LED 50W is equipped with a 2.8-inch TFT-LCD display using IPS technology, offering a 178° viewing angle to ensure clear information readability from all directions. The screen brightness adjusts automatically, increasing to 800cd/㎡ in strong light and dropping to 100cd/㎡ in low light, balancing readability and energy savings.

Information Publishing System

Supports multiple content formats, such as images (JPEG, PNG), text (TXT), and simple animations (GIF). It connects to upper computers or cloud platforms via RS485 or WiFi communication interfaces for remote information updates and management.

Screen Protection Design

To adapt to outdoor harsh environments, the LED screen uses high-strength tempered glass panels with Mohs hardness 7H and strong impact resistance. Sealed waterproofing on all sides achieves an IP65 protection rating, resisting rain and dust erosion.

Internal circuits are potted to isolate moisture, ensuring stable operation within a wide temperature range of -20°C to +60°C and extending screen lifespan.
