Voorbeeldzinnen

1. ‘Gas-discharge light source’ means a light source where the element for visible radiation is a discharge arc producing electro-luminescence/fluorescence;
2. ‘Light-emitting diode (LED) light source’ means a light source where the element for visible radiation is one or more solid state junctions producing injection-luminescence/fluorescence;
3. A computer controlled rate monitor operating on the principle of photo-luminescence of the ionised atoms in the evaporant stream to control the deposition rate of a coating containing two or more elements;
4. Flat screen monochrome cathode-ray tube, with a diagonal measurement of the screen of 142 mm or more but not exceeding 190 mm, a luminescence of 300 lumen or more but not exceeding 2000 lumen, a resolution of 0,06 mm or more but not exceeding 0,1 mm, phosphor types P1 or P22 or P53 or P55 or P56, an anode voltage of more than 34 kV, a focus voltage of more than 7 kV and a cathode current of 3 mA or more
