Abstract
It is important to control the beam pattern of an LED by the design of a reflector. The optimum conditions of the structure parameters for the 2 segment LED reflector are analyzed and compared as they vary depending on the various intensity distributions of light output on the LED chip surface. It is also interesting that combining various types of reflectors is possible to give several efficient beam patterns, such as the maximum intensity profile or relatively wide controllability of beam angle.
