The lighting industry is presently exploring the use of additive manufacturing for creating light fixtures for general illumination applications. Optical components play an important role in a light fixture by creating a tailored beam pattern that caters to the lighting application’s requirements and affecting the lighting system’s overall efficacy. Generally, light fixtures use transmissive or reflective optics that have been injected molded using polymers. In the past several years, the Lighting Research Center at Rensselaer Polytechnic Institute has explored the design and 3D printing of optical components for lighting. These investigations have used different print techniques and print parameters, and the resulting optics have been evaluated in the laboratory for their performance over both the short and long term. Some of the optics designs explored were only possible to manufacture using additive manufacturing methods. This presentation will include the designs, manufacturing parts, and performance results of several additively manufactured lighting optics.
