F5000 transient digital photometer with 16 bit high speed (1MSPS) high precision AD can achieve maximum 50 KHz sampling frequency, the shortest test interval of 10 us, maximum sampling points to 8000000 points. It can be equipped with a variety of high-speed optical photodetector. High precision and fast detect the parameters of the illuminance, luminance, luminous flux, luminous intensity, radiation degrees. Through software analysis, the intensity, frequency, scintillation index, scintillation percentage and other parameters are obtained.

Standard requirement:

  In the requirement of dimming performance, American energy star stipulates the requirements for the flashing of all lights:

(1) the frequency is not less than 120Hz;

(2) within the frequency range of 120Hz~800Hz, the scintillation index FI≤0.001 * frequency;

(3) when the frequency is greater than 800Hz, there is no requirement for the scintillation index F1.

Introduced the United States energy star standards V1.0 since September 1st, 2014, There is no specific limit for the scintillation index, but provides for all products that move light energy star in the declaration, must report the frequency of the light output cycle, the maximum percentage of flashing and flashing index and dimming working conditions.
