Passive cooling lighting fixture

摘要

A passive cooling lighting fixture that includes a light diffusing lens. The fixture is self-contained and self-cooled in order to maximize the life span of the light source. The passive cooling system utilizes vented end caps that circulate cool air into the lighting fixture while venting hot air out of the lighting fixture. The light diffusing lens produces a light that is soft enough for use indoors.
