Abstract
Directional emission characteristics of various reflectors are compared by ray tracing analysis taking into account the directional reflectivity of mirror surfaces. For the case of a perfect reflector surface, the aperture of an involute reflector has an isotropic uniform distribution of radiant intensity. The hemispherical emissive power and directional radiant intensity of the involute reflector for metallic surfaces are slightly lower than the values for the ideal case. The distributions of emissive power and directional radiant intensity of conventional reflectors are significantly nonuniform compared with those of the involute reflector.
