Heat-dispersion-elements for cooling light-module-inserts, as well as methods for cooling and systems for cooling are described. The heat-dispersion-element may have an outer arc and disposed opposite an inner arc. At least portions of the outer arc may be in direct physical contact with at least some portions of inside-surfaces of a housing. At least portions of the inner arc may be in direct physical contact with at least some portions of outside-surfaces of the light-module-insert. The heat-dispersion-element may be located between the light-module-insert and the housing. The heat-dispersion-element may have an overall torus or torus like shape, or a partial torus like shape. The heat-dispersion-element may have a base and fingers extending from that base. The base may be curved into the outer arc. The fingers may be curved to form the inner arc.
