Introduction

Technical Parameters

Certificate

Excellent compatibility for different national or international standard

Features

1. LED

• 3~5-year service life, reduce the cost for maintenance and replacement.
• Comparatively, LED could save 80% energy compared to incandescent light, save 50% compared to fluorescent lamp, and save 70% compared to HPSL (high pressure sodium lamp).
• Semiconductor material, ALL parts can be recycled.
• Visual-friendly.
• Closer to natural daylight.
• As a solid light source, LED has outstanding performance in shake-resistance, not easy damaged.
• Can be connected to an external battery, working voltage is 85~265V AC, the voltage fluctuation would not affect its performance and service life.
• -40 ℃~+60 ℃ working temperature
• Power could be adjusted, provides possibilities for future expansion on intellectualized functions.

Types for different occasions:

1. Street Light
2. Tunnel Light
3. Flood Light

Types driven by different energy source (can be mixed type):

1. Electricity driven
2. Wind power driven
3. Solar panel driven

2. Concentrator Unit:

• Data collection: data acquisition of watt-hour meter, state quantity collection (reservation), data acquisition of street lighting controller.
• Data storage and management: real-time and current data, historical data, watt-hour meters, street lighting controllers and other equipment operating status monitoring.
• Parameter setting and tracing: management policy settings and tracing, terminal parameters, street lighting controllers, summary table parameter, calling for clock and timing.
• Controlling: local control (according to management policy setting/local command), remote control (command issued by master station)
• Event recording: important event record, general event record.
• Data transmission: communication with master station, street lighting controller, watt-hour meter, and user data interface.
• Local function: displays relevant information, respond to human-computer interactive input, user data interface
• Smart maintenance unit: Self-examining and self-recovery, remote terminal initialization, software remote upgrade.

3. Single-capped Lamp Controller:

• Controlling Function: through the voltage output of the power line carrier wave adjustment controller 0~10V, and the PWM duty cycle output, the dimming range is 0%~100%, the electrodeless dimming is less than 2%, and the adjustment accuracy is less than 2%.
• Measuring Function: built-in electric energy measurement function, the measurement accuracy can reach 2%
• Monitoring Function: each lamp can be monitored remotely, and the voltage, current, power, power factor and working status of the street lighting can be monitored at any time.
• Alarming Function: the running status of the controller can be reported in real time through the power line carrier, including overvoltage, overcurrent, overload, abnormal lamps and lanterns, etc. At the same time with anti-theft of electricity, cable anti-theft and other functions.
• Parameter Setting: parameter setting and maintenance can be done remotely.
• Protection Function: equipment will automatically alarm and shut down when the temperature is too high, or the power is too high, or the voltage is too high or too low. When the temperature is too low and the output circuit is open, it will alarm until the fault is removed.

Situation

Intercity highway, urban road, rural road,tunnel, culvert, road intersection, large square, open space required strong lighting.
