    Abstract: A method of rapid prototyping a lighting system which is at least one of folded path and multifaceted includes determining output power of the lighting system by calculating phase space density. A method of rapid prototyping a lighting system comprises ray tracing the lighting system, determining photometric quantities which describe the lighting system based on the ray tracing step, and providing a stereoscopic three-dimensional rendering of the lighting system based on the determining step. Advantageously, three-dimensional renderings promotes rapid prototyping by revealing any hidden pseudo-image artifacts in a lighting system before the lighting system is actually fabricated. A computer system for rapid prototyping a lighting system comprises a plurality of slave processors networked to a host processor. The slave processor and the master processor cooperate to ray trace the lighting system, and the slave processors perform substantially homogeneous independent tasks. Advantageously, the computer architecture allows the homogeneous independent tasks to be distributed to the plurality of slave computers, so that the overall amount of time required to perform the tasks is drastically reduced. Again, this promotes rapide prototyping by decreasing the amount of computational time required to generate useful information about a prototype lighting system.

    Abstract: A non-scattering light pipe (10) includes a transition surface (28, 30) between a first side wall (14) and an input suface (12) and a second side wa ll (16) and the input surface (12). The transition surface is arranged to substantially obscure the corner interfaces (36, 38) between the first and second side walls and the input surface such that in the corner formation an y imperfections therein are not imaged into the output. Most preferably, the transition surface is optimized to provide a substantially uniform light intensity distribution. A light pipe in accordance with the preferred embodiments of the present invention is further arranged to couple a linear light source (306), such as a cold cathode fluorescent light (CCFL). The lig ht source is arranged such that dim areas (337', 338'), i.e., areas of the ligh t source having non-uniform intensity, are not disposed adjacent the input surface.
