Test methods of rare earth trichromatic phosphor lamps
Part 1. Determination of relative brightness
1 Scope
GB/T 14634 provisions of this part of the determination of the relative brightness of the light rare earth trichromatic phosphor methods.
This section applies to the determination of the relative brightness of the phosphor in trichromatic lamps.
2 principle of the method
Light rare earth trichromatic phosphors emit visible light at 253.7nm UV excitation through by V (λ) function corrected photodetector
Will convert it into a photocurrent or photovoltage, record the value, and then the same standard phosphor under the same conditions measured photocurrent or photovoltage
Value comparison, the relative brightness of the light rare earth trichromatic phosphor.
3 instruments and apparatus
3.1 of the sample excitation, measurement conditions
3.1.1 "0/d" refers to the excitation light direction perpendicular to the sample surface, sample fluorescence was collected by an integrating sphere. Integrating sphere wall is coated with non-fluorescent neutral Man
Reflective material, reflectance (80 ± 5)%.
3.1.2 "45/0" refers to the direction of the excitation light and the sample surface normal direction at 45 °, the direction perpendicular to the receiving surface of the sample.
3.1.3 "0/45" refers to the excitation light direction perpendicular to the sample surface, the direction of accepting the sample surface normal 45 °.
3.2 Instrument Principle
Instrument principle is shown in Figure 1.
figure 1
3.3 excitation light source
Emitting 253.7nm ultraviolet low pressure mercury lamp, power of 2W ~ 20W, with 253.7nm UV filter, the filter
Peak transmittance greater than 10%, in the wavelength range of 300nm ~ 800nm \u200b\u200btransmittance of not more than 0.1%; the excitation of the light source is not stable
Less than 0.2%.
3.4 Sample Tray
Made of stainless steel, diameter ≥20mm, edge width ≤0.5mm, depth ≥3mm.
3.5 photodetectors
Relative spectral responsivity and V (λ) consistent spectral responsivity of the detector line with a V (λ) photodetector requirements.
3.6 meter reading
Reading instrument linearity better than 0.2%, the standard phosphors, the instrument displays the maximum reading of not less than 100, the resolution is not less than 0.1.
3.7 standard phosphor selection
According to Table 1, selecting the sample to be tested corresponding standard phosphor.
