We will change the Weight exponent to -5, but before doing so, first increase it from the default of 1 to 3. We will modify some of the parameters that will narrow the beam angle and increase the amount of light aimed toward the beam center.Ĭhange the Start angle to 27.5 and click Update Aiming. This will open the PODT view showing all the reflector design parameters. Select the reflector in the CAD view and then click Design reflector. The aiming angles are defined by the start and end angles of the beam spread, as well as the angular increment between those 2 limits.Īssuming the bottom of the reflector aims light toward the widest angle, the top toward the center, and increments between those two extremes of 2.5°, the values we enter for start, end and increment are -30, 0 & 2.5. We will start with aiming the light 30° from the beam center and the aiming can be adjusted once we see how the reflector performs. In order to achieve 50% of the peak intensity at 20°, you'll need to aim light beyond that angle since the beam will continue to taper past the 20°. The peak intensity for this design should also be in the beam center. The goal of this design is to create a 40° beam angle, which means the 50% intensity values will be 20° to either side of the beam center. The aiming angles define how you want to aim the light from the reflector. The Angular extent sweeps from the start point to a radial line that defines the end of the reflector. The image below shows references for the Aiming Nadir, Angular Extent, and Aiming Angle Directions.
