This standard specifies the energy efficiency levels, energy efficiency limits, and test methods of LED flat lamps for general lighting. This standard applies to LED flat panel lamps for general lighting, with LED as the light source, rated voltage of 220 V, frequency of 50 Hz, and thickness not exceeding 85 mm, including LED light sources and their control devices. The thickness of external control devices is not included in the thickness of the lamp. This standard does not apply to LED flat panel lights with non lighting additional functions that consume energy, LED flat panel lights with dimming/color adjustment functions, and LED flat panel lights with colors, patterns, or decorative elements on a continuous emitting surface. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 24826 Terminology and Definitions for LED Products and Related Equipment for General Lighting GB/T 31897.201 Luminaires Performance Part 2-1: Special Requirements for LED Luminaires 3 Terminology and Definitions GB/T 24826 defines and the following terms and definitions apply to this document. 3.1 LED flat panel luminaire is a thin type luminaire that uses LED as the light source and only emits downward light. Its luminous surface is a regular square, rectangular, or circular continuous plane, with a aspect ratio of no more than 5 and a maximum side length or diameter of no less than 270 mm. 3.2 Luminous efficiency of LED flat panel luminaire The ratio of the initial luminous flux emitted by the LED flat panel lamp to the input power under standard testing conditions
Function of testing report:
