Thermal Resistance Spectroradiometric System for LED

Thermal parameters constitute the critical performance indicators for LED quality assessment. Temperature variations significantly impact optical parameters, colorimetric parameters, electrical parameters, and operational lifespan of LED devices. Consequently, thermal management design and control represent essential considerations for manufacturers and end-users. In accordance with relevant international standards including IEC 60747-5-3, the TRS-1000 system performs integrated testing of optical, colorimetric, electrical, and thermal parameters while recording real-time parameter variation curves.
