LS280 Multiplex Optical Maintenance Meter

LS280 Multiplex Optical Maintenance Meter is utilized for measuring optical maintenance factor in accordance with IEC 62612 for high-power LEDs, LED modules, LED bulbs, and other LED luminaires. This instrument serves as essential equipment for conducting reliability assessments of illuminants.

Measurement Capabilities:

• Illuminance Maintenance: Curve, factor, and data (lx vs. time)
• Luminous Intensity Maintenance: Curve, factor, and data (cd vs. time)
• Luminous Flux Maintenance: Curve, factor, and data (lm vs. time) – Requires integrating sphere

Key Features:

• Configurable time interval and duration for automated measurement sequences
• LCD display with RS232 interface and English-language PC software
• Test results exportable to Excel or PDF formats for comparative analysis
• Data storage via LS280 software or direct USB connection
• Enables LED lifespan analysis based on collected test data
• Integrates with LS600 High-Power LED Aging Test System, TMP-8/TMP-16 Multiplex LED Temperature Test Systems, and GDJS-*B High/Low Temperature & Humidity Chambers to perform flux vs. temperature vs. time measurements, creating a comprehensive instrument system for LM-80 compliance

Technical Specifications:

• Standard configuration: 1 group with 8 channels (tests 8 LED products simultaneously)
• Optional expansion: Up to 8 groups with 64 channels (tests 64 LED products simultaneously)
• Illuminance range: 0.100 lx to 400 klx; Accuracy: ±(2.0% + 0.5)
• Luminous intensity range: 10 mcd to 40 kcd; Accuracy: ±(2.0% + 0.5)
• Luminous flux range: 10 mlm to 9,999,000 lm (dependent on integrating sphere dimensions); Accuracy: ±(2.0% + 0.5)
• Maximum time range: 9999 hours, 59 minutes, 59 seconds
• Timer precision: ±1 second per 10 hours
