Compliance Framework

EN 50121-3-2: Electromagnetic Compatibility for Railway Applications

Technical Requirement	Design Implementation	Validation Standard
Controlled Conducted & Radiated Emissions	Optimized PCB shielding, common-mode filtering and isolated grounding architecture	Zero interference with on-board CAN bus, ATP safety systems and GSM-R communication equipment
Full-Spectrum Interference Immunity	Complete test coverage for ESD, RF radiation, electrical fast transients and surge pulses	Achieves Class B EMC certification for railway onboard devices
Transient Voltage Endurance	Specialized circuit protection against brake voltage spikes and pantograph arc disturbances	Stable, flicker-free luminous output with no abnormal flash alarms during transient surges

EN 50155: Electronic Equipment Used on Rolling Stock

This standard sets the mandatory certification baseline for all onboard electronic assemblies, with all our lighting control modules fully compliant:

Power Compatibility: Supports mainstream on-board DC supplies of 24V / 48V / 72V / 110V; withstands 70%~125% nominal voltage fluctuations and maintains full illumination during 10ms instantaneous power outages
Environmental Resilience: Operates reliably across -30°C to +70°C; validated through high-temperature aging and low-temperature cold-start testing
Mechanical Robustness: Passes 5–150Hz random vibration and mechanical shock benchmarks, eliminating risks of light source detachment, housing cracking or driver circuit failure over long-term operation
Multi-Layer Circuit Protection: Constant-current driver circuits integrate overvoltage, overcurrent, short-circuit and thermal lockout safeguards, engineered for 24/7 uninterrupted train service

IEC 60598	General Safety Requirements for Luminaires	Minimum IP54 dust and water ingress protection; structural safeguards against electric shock and overheating hazards

Dual-Tier System Architecture

Normal Lighting System (Primary Main Illumination)

Core Function: Delivers consistent baseline illumination for passenger saloons, driver cabs, connecting gangways and passenger boarding vestibules

Power Distribution: Zoned centralized power supply controlled via the vehicle’s main switchboard

Product Category	Typical Installation Scenarios	Key Technical Features
General Ceiling Luminaires	Primary ambient lighting for passenger compartments	Stepless dimming capability, homogeneous light distribution, flicker-free operation
Local Auxiliary Lights	Passenger bedside reading lamps, vanity mirror fixtures	Adjustable directional beam optics, switchable CCT ranging from 3000K to 6500K
High-Intensity Floodlights	Cargo wagons, maintenance bays and equipment storage rooms	High luminous flux output, wide beam angles, dust and contamination-resistant surface treatment
Continuous Corridor Lighting	Passageways, inter-car gangways and stairwells	Linear continuous layout with built-in linkage compatibility for emergency lighting activation

Integrated Intelligent Control Functions

Supports zone-based manual and automatic brightness dimming
Programmable linkage with train operational modes: Day Mode, Night Mode and Tunnel Compensation Mode
Independent wiring harnesses for each zone distribution panel to contain fault propagation and prevent cascading power failures

Emergency Lighting System (Backup Safety Illumination)

Core Function: Dedicated isolated power circuits with automatic 5-second switchover upon main power loss, fully aligned with EU passenger evacuation safety regulations

Activation Triggers

⚠️ Main traction generator shutdown fault
⚠️ Complete voltage depletion on the lighting busbar
⚠️ Interlock signal input from the fire alarm control panel
⚠️ Manual forced activation via the driver’s cab control console

Covered Zones & Performance Parameters

Zone Classification	Minimum Illuminance	Backup Runtime	Structural Configuration
