Overview
The ZOLIX Chame-LH200 LED Luminous Flux Measurement System is a precision optical metrology instrument engineered for traceable, repeatable photometric characterization of solid-state lighting devices. Based on the fundamental principle of integrating sphere photometry—where light from a source is diffusely reflected multiple times within a highly reflective spherical cavity to produce spatially uniform irradiance at the detector—the Chame-LH200 enables absolute luminous flux (lumens) and radiant power (watts) measurements in accordance with CIE Publication No. 84 and ISO/CIE 130-1:2021. The system supports dual-integration-sphere configurations: a compact 200 mm sphere optimized for routine QA/QC of mid-power LEDs and SMD packages, and a larger 500 mm sphere designed for high-flux emitters including COB arrays, high-brightness single-die LEDs, and miniature lamp modules. Its architecture complies with the geometric and spectral requirements for photometric standardization under ILAC-P10 and NIST-traceable calibration frameworks.
Key Features
- Dual-integration-sphere platform: Interchangeable 200 mm and 500 mm spheres with certified BaSO₄ or Spectralon® coatings (reflectance ≥97% across 380–780 nm)
- Thermally stabilized silicon photodiode detector with V(λ)-matched filter assembly meeting CIE 1931 photopic luminosity function tolerances (f₁′ ≤ 1.5%)
- Integrated reference channel for real-time drift compensation and long-term measurement stability
- Programmable current source for precise DC/DC forward bias control of LED devices under test (DUT), supporting constant-current and pulsed-drive modes
- Optical baffle and port geometry engineered to minimize first-reflection errors and sphere wall non-uniformity effects
- Compliance-ready design: Supports audit trails, user access levels, and electronic signature capability aligned with FDA 21 CFR Part 11 and ISO/IEC 17025 documentation requirements
Sample Compatibility & Compliance
The Chame-LH200 accommodates a broad range of LED form factors—including 20–5050 SMD packages, TO-can emitters, ceramic-based high-power LEDs, and multi-chip COB modules—via standardized mechanical fixtures and thermal management interfaces. All measurements adhere to international photometric standards: CIE S 025/E:2015 for LED testing, IES LM-79-19 for electrical and photometric measurements of SSL products, and EN 13032-4:2020 for integrating sphere instrumentation validation. Calibration certificates are issued with uncertainty budgets compliant with GUM (JCGM 100:2008) and include spectral mismatch correction factors for each LED color bin (R/G/B/white). The system meets GLP laboratory infrastructure requirements for environmental monitoring (temperature ±0.5°C, humidity 30–60% RH) during photometric acquisition.
Software & Data Management
The proprietary ChameSoft v3.2 application provides full instrument control, spectral data acquisition, and photometric computation in a validated Windows environment. It features automated sequence execution for multi-sample batch testing, real-time spectral radiance visualization, and export of results in ASTM E308-compliant .qtx format. Data integrity safeguards include immutable audit logs recording operator ID, timestamp, calibration status, integration time, and DUT operating conditions. Raw spectral data and processed photometric values are stored in ACID-compliant SQLite databases with optional synchronization to enterprise LIMS via HL7 or RESTful API. Software validation documentation (IQ/OQ/PQ protocols) is available upon request for regulated environments.

FAQ
What calibration standards does the Chame-LH200 support?
The system accepts NIST-traceable calibration using standard lamps (FEL, SL) and LED reference standards certified to CIE 127:2007 Annex B. Factory calibration includes spectral irradiance responsivity mapping across 360–830 nm.
Can the instrument measure pulsed LEDs?
Yes—integrated trigger synchronization enables gated integration synchronized to external pulse generators with widths from 10 µs to continuous DC, preserving photometric accuracy under transient operation.
Is spectral power distribution (SPD) data output available?
The Chame-LH200 is a broadband photometer; SPD acquisition requires optional integration with a calibrated spectroradiometer (e.g., ZOLIX Omni-λ + SR series).
How is thermal management handled during high-power LED testing?
The system includes thermally isolated DUT mounts with integrated PT100 sensors and optional water-cooled heat sinks compatible with 500 mm sphere configurations.
Does the software comply with 21 CFR Part 11?
ChameSoft v3.2 includes electronic signatures, role-based access control, and audit trail generation—all validated per Part 11 Annex A guidance for computerized systems in regulated laboratories.
