Abstract
A system, in certain embodiments, includes a high intensity discharge lamp having a composite leg. The composite leg includes a plurality of leg sections coupled together in series. The plurality of leg sections includes different materials, coefficients of thermal expansion, Poisson's ratios, or elastic moduli, or a combination thereof. A method, in certain embodiments, includes enclosing a high intensity discharge within a ceramic arc envelope. The method also includes reducing thermal stresses associated with the high intensity discharge via a composite leg extending outwardly from the ceramic arc envelope. The composite leg includes a plurality of leg sections coupled together in series. The plurality of leg sections includes different materials, coefficients of thermal expansion, Poisson's ratios, or elastic moduli, or a combination thereof.
