Reflector development and photometrical analysis with AIMLIGHT®

Development task:
Close beaming reflector for metal halide lamp HIT 150 W, half-peak divergence approx. 20 °

Size of the luminaire opening 193,5 mm
Focal point from luminaire opening 74,96 mm
Opening in the reflector center Ø 33 mm

The maximum angle of incidence of 141,6° achieves the required opening in the reflector center. With 0° cut-off angle from reclector border and reflector center a focused light beam is generated. Choose corresponding lamp.

Choose suitable surface.
Because of very little calculation periods, alternatives can be tested very fast.
The reflector graphic informs about the diffusion of the light rays (maximum cut-off angle) and the shielding angle. Unwanted reflections through the arc can be checked. The photometric analysis shows, that the desired half-peak divergence is achieved with a sand blasted surface (eroding texture 27).

In the luminous intensity table you can alternatively view the candela-values or cd/klm. With the sum of the zonal lumens from 0-90° the optical efficiency is calculated. The Eulumdat or IES files which are created with AIMLIGHT® can immediately be used in lighting calculations.

With AIMLIGHT® reflector calculations can be performed within a few minutes.
For example the calculation of the light intensity distribution for a rotationally symmetrical reflector takes only five seconds on a PC with Intel® Pentium™ III or comparable processor.
