200mm Single-Faced Four-Light Portable Traffic Light

Compact Traffic Light Diameter: Refers to a signal light housing with a diameter of 200 millimeters, offering excellent visibility and warning effectiveness.
Single-Panel Four-Light Design: Typically refers to a single panel that integrates red, yellow, and green traffic signals, along with an additional countdown display (or auxiliary warning light), providing more comprehensive information.
High-Brightness LED Light Source: Utilizes highly efficient, energy-saving LEDs characterized by ultra-high brightness and low power consumption, with an extremely long service life (typically 50,000 to 100,000 hours), making them economical and durable.
Multiple Control Modes: Supports various modes, including multi-time-slot timer control, manual control, and intelligent yellow-flash control. The system typically features data retention capabilities, ensuring that operating parameters are not lost even in the event of a power outage.
Fail-Safe and Diagnostics: Equipped with robust intelligent diagnostic capabilities (such as 2-channel diagnostics). In the event of communication failure or signal conflicts (e.g., green light conflict, all red lights off), the system automatically switches to a safety mode such as yellow flashing to ensure traffic safety at the intersection.
Dual-Mode Power Supply System: Primarily powered by solar energy, featuring high-power solar panels and batteries (e.g., a 60W solar panel paired with a 55Ah battery), making it environmentally friendly and eliminating the need for external power cables; It is also equipped with a mains power backup charging device to ensure 24/7 uninterrupted operation during prolonged rainy periods or insufficient sunlight.
Intelligent Charge/Discharge Protection: Features a built-in smart controller with automatic protection against reverse connection, overcharging, over-discharging, and short circuits, effectively extending battery lifespan.
