Abstract
A method and apparatus for an air vent assembly is provided in which individual louvers and spacers are connected together to form chevron shaped channels that allow increased air flow while blocking the escape of direct light. The louvers are formed into a chevron shape that extends lengthwise from one end of the louver to another end of the louver. The spacers are chevron shaped and interlock or are bonded together with one another to secure the louvers and to provide a support structure such that additional spacers and louvers may be stacked together as needed to form an air vent for use in a given device.
