The achievements of modern optoelectronics have resulted in the widespread use of light-emitting diodes (LEDs) in products designed to visualize information, especially in light devices for use in road-safety systems. These developments highlight the importance of metrological support for measurements of the photometric characteristics of semiconductor light sources. A standard light-source model based on Corvette Light Corporation high-luminance LEDs has been created and studied. The high-luminance LEDs were manufactured to a unique design using planar technology. The results of the study demonstrate the stability of the metrological characteristics of the LED-based standard source.
