LED Light Sources Tests and Requirements Standard
This SAE Recommended Practice provides the methods of measurements for electrical and photometric characteristics of LED packages. It provides procedures, requirements, and guidelines for the methods of the measurement of luminous flux and color maintenance of LED devices (packages, arrays, and modules) for ground vehicle lighting applications.
Rationale: Changed title. Added into scope to include the methods of measurements for electrical and photometric characteristics of LED packages. Added references. Revised 3.5. Section 4 title is changed to Tracking, and contents have been revised. Added 5.1 for LED package measurement. Re-numbered 5.2 for LED source luminous flux and color maintenance test. Revised the contents. Section 6 was added to address test requirements. The electrical and optical measurements for LEDs are referred to other IES and CIE standards. For the luminouse flux maintenace level requirements, it should be refer to the corresponding SAE application documents. For color binning and qualification requirements, it will refer to the IEC standards.
