      The device is designed to measure the total luminous flux of LEDs by the “integrating sphere” method (“Ulbricht Spheres”), in lumens.

      Structurally, the device consists of two functional blocks. The sphere diameter is 140 mm, the light receiver is a photodiode located in the lower hemisphere. The measuring unit is made in the form of a ball on a rigid base, the ball is an “integrating sphere”. It has an entrance tube for installing LEDs up to 14 mm in diameter and replaceable diaphragms included in the kit for positioning LEDs with diameters of 3, 5, 9 mm.

      The integrating sphere inside is painted with white, diffusely reflecting paint with a reflectance ρ = 96%. The geometric dimensions of the entrance window and the seat for the measured LED are shown in the figure.

      Ambient temperature from 0 to +50 ° C
      Relative air humidity at an ambient temperature of 25 ° С 65 ± 15%
      Atmosphere pressure 80 ÷ 110 kPa
