Abstract

An LED module or assembly is disclosed, the assembly having at least one LED component mounted on a support or circuit board and an optical element which encloses the at least one LED component and defines an interior space in which the at least one LED component is housed. A vent device is defined within the optical element for permitting gases generated from operation of the at least one LED component to be vented to atmosphere. The vent device prevents outside moisture from entering the interior space, but permits the gases to pass out to atmosphere for minimizing the likelihood of fogging of the optical elements in the interior space of the assembly.
