goniometer

Voorbeeldzinnen

1. Any offset of the centre of reference of each lighting unit, with respect to the goniometer rotation axes, should be avoided.
2. Each applied position is realized on the test goniometer with respect to a line joining the centre of the light source and point HV on a aiming screen.
3. Each applied position is realized on the test goniometer with respect to a line joining the centre of reference and point HV on an aiming screen.
4. The system or part(s) thereof shall be mounted on a goniometer with a fixed horizontal axis and moveable axis perpendicular to the fixed horizontal axis.
5. Having re-aimed the system or part(s) thereof as a whole (by means of the goniometer for example) in the corresponding opposite direction the light output in the following directions shall be controlled and lie within the required limits:
6. swivelling the passing beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been re-aimed horizontally, e.g. by means of a goniometer;
7. in case of a category 1 or a driving beam bending mode: after having horizontally re-aimed the relevant installation unit (by means of the goniometer for example) in the corresponding opposite direction.
8. The illuminance values shall be determined by means of a photoreceptor contained within a square of 65 mm side and set up to a distance of at least 25 m forward of the centre of reference of each lighting unit perpendicular to the measurement axis from the origin of the goniometer;
9. The angular co-ordinates are specified in deg on a sphere with a vertical polar axis according to CIE publication No 70, Vienna 1987, i.e. corresponding to a goniometer with a horizontal (‘elevation’) axis fixed to the ground and a second, moveable (‘rotation’) axis perpendicular to the fixed horizontal axis.
