Position and form of the arc
This test is used to determine the form of the arc and its position relative to the reference axis and the
reference plane by measuring its bending and diffusion in the cross section at a distance 27.1 mm from
the reference plane.
Relative luminance distribution in
the central cross section D.
The form of the arc is for
illustration purpose only.
Measuring direction:
light source side view
When measuring the relative luminance distribution in the central cross section as indicated in the
drawing above, the maximum value shall be located within the distance r from the reference axis. The
point of 20% of the maximum value shall be within s. The geometrical data is valid for 27W and 35W
operation.
Dimension in mm Production light sources Standard light sources
r (arc bending) 0.35 ± 0.25 0.35 ± 0.15
s (arc diffusion) 0.80 ± 0.25 0.80 ± 0.15
