IMPROVED VENTING SYSTEM FOR MINIMIZING CONDENSATION IN LIGHTING ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for reducing condensation in a lamp housing.

SOLUTION: A lighting assembly includes: a housing 20 defining an internal space within the housing, and an ambient space surrounding the housing; a light source within the internal space; a high capacity desiccant 22 being nonregenerating at temperatures of up to about 50 degrees Celsius and about 11.0% relative humidity; and a diffusion tube 12 having a first opening proximate to the internal space and a second opening proximate to the ambient space, the diffusion tube providing gaseous communication between the internal space and the ambient space.
