Betekenis van:
beam of light

Voorbeeldzinnen

1. A beam of white light is split by a prism into rays of various colors.
2. A beam of light through the window woke the professor up out of a deep sleep.
3. ‘Principal passing beam (principal dipped beam)’ means the dipped beam produced without the contribution of infrared (IR) emitter and/or additional light sources for bend lighting.
4. Main-beam headlights shall be represented by parallel horizontal rays of light and dipped-beam headlamps by parallel rays of light angled downwards.
5. Machine tools for working any material by removal of material, by laser or other light or photon beam, ultrasonic, electrodischarge, electrochemical, electron beam, ionic-beam or plasma arc processes
6. The light output must be collimated to a beam with a maximum diameter of 30 mm. The rays of the light beam must be parallel within a tolerance of 3° of the optical axis.
7. special instruction, if any, for the inspection of the light sources and the visual observation of the beam;
8. With no blockage of the opacimeter light beam, the readout must be adjusted to 0,0 % ± 1,0 % opacity.
9. Bend lighting may be produced by activating one additional light source being part of the passing beam headlamp.
10. Machine tools for working any material by removal of material, operated by laser or other light or photon beam processes
11. It shall be possible to remove the central part of the diaphragm from the light beam in such a manner that it returns exactly to its original position.
12. in the case where a test sample is designed to provide only one lighting function (driving beam or passing beam) and not more than one class in case of passing beam, the corresponding light source(s) is/are lit for the time [1] specified in paragraph 1.1. above;
13. In the case of a test sample designed to provide a passing beam bending mode with an additional light source being energized, said light source shall simultaneously be switched on for 1 minute, and switched off for 9 minutes during the activation of the passing beam only, specified in (a) or (b) above.
14. One additional light source or one or more LED module(s), located inside the dipped-beam headlamps or in a lamp (except the main-beam headlamp) grouped or reciprocally incorporated with the respective dipped-beam headlamps, may be activated to produce bend lighting, provided that the horizontal radius of curvature of the trajectory of the centre of gravity of the vehicle is 500 m or less.
15. ‘Lighting unit’ means a light emitting part of the system, which may consist of optical, mechanical and electrical components, designed to provide or contribute to the beam of one or more front-lighting function(s) provided by the system;
