3 relative brightness determination

3.1 Principle of the method With a peak emission at 460nm monochromatic light as the excitation source, a rare earth silicate phosphor LED excitation fluorescence generated by income After the set, by by V (λ) function corrected photodetector to convert optical signals into electrical signals. Under the same conditions the standard relative luminance samples tested Photocurrent value product with the sample, relative to the luminance of the standard sample photocurrent is 100%, the relative brightness value read out of the sample. 3.2 Instruments and means 3.2.1 The relative brightness meter. Accuracy ± 0.5%. 3.2.2 excitation light source. the blue LED and a filter composed of the excitation light peak wavelength of 460nm. Vertical excitation light to excite the sample tray After the sample, and the sample fluorescence emitted in the normal direction of 45 ° is collected. After the excitation light is lit 10min, stability is better than 0.1%. 3.2.3 Sample dish. made of stainless steel, diameter φ28mm ± 0.5mm, depth 3.0mm ± 0.1mm. 3.2.4 photoelectric detector. detector spectral response rate at the national level in line with the requirements of illumination detector, scanning interval of 5nm. 3.2.5 Calibration substances. barium sulfate (AR), the standard light source. 3.3 Test Environment 3.3.1 Ambient temperature. 25 ℃ ± 3 ℃. 3.3.2 Relative humidity. ≤80%. 3.3.3 Environmental illumination. in a dark environment, avoid light interference. 3.4 standard sample GSB04-3066-2013LED rare earth silicate phosphor relative brightness of a standard sample. 3.5 Test Procedure 3.5.1 Turn the relative luminance meter (3.2.1), the excitation source is lit steady 15min, while the test instrument to warm up 15min, referring to the instrument Instructions calibration instruments. 3.5.2 The relative brightness of a standard sample (3.4) and the samples were loaded into the tray, flatten with the flat glass to make the surface smooth. ......
