Abstract This topic is about the development of a 2-dimensional specular reflector design aid software. For a long and cylindrical shaped lamp with perfect diffusing surface, direction and quantity of reflected light flux from a specular reflector strip can be calculated considering reabsorption by the lamp itself. Assuming a reflector as a combination of several strip segments, the reflected flux is calculated as position, length and declination of each segment are determined. At each step, calculated reflected flux distribution and desired flux distribution is compared graphically and numerically, so that most optimized and efficient reflector shape can be decided by the designer. We think that this software would be useful for designing reflectors for relatively long light sources, such as fluorescent lamp, tubular high pressure sodium lamp, low pressure sodium lamp, and so on.
