Scope

GB/T 39394-2020 (Test method for LED lamps, LED luminaires and LED modules) is available as an English-translated PDF.

GB/T 39394-2020 is the Chinese standard "Test method for LED lamps, LED luminaires and LED modules". Its scope clause reads: This standard specifies the requirements of LED lamps, LED lamps and LED modules that are powered by AC or DC and may be equipped with LED control devices.

Measurement methods for electrical, photometric and chromaticity parameters. The LED light engine is similar to the LED module and can be implemented by reference.

The light covered in this standard Degree and chromaticity parameters include total luminous flux, luminous efficiency, partial luminous flux, light intensity distribution, central beam intensity, brightness and brightness distribution, chromaticity coordinates, Correlated color temperature (CCT), color rendering index (CRI) and spatial color non-uniformity.

This standard does not apply to LED packaging and organic-based LEDs (OLED) products.
