In order to improve the facular-shaping effect of the microcylinders and lens duct, a new duct with changing elliptical cross section was proposed. The long axis of the ellipse on the front surface is located in horizontal direction, which matches the light emitting distribution pattern, The long axis of the ellipse on the back surface gradually become in vertical direction. The 3-D ray-tracing simulation indicates that the irregular duct can achieve relatively good circular symmetric pumping energy distribution. The energy transferring efficiency of microcylinders and the duct is calculated to be 90.84% and 91.98% respectively, corresponding to the total efficiency of 83.55%. The contrast indicates that the irregular duct possesses some advantages in facular shaping and energy transferring efficiency over common ducts.
