Patent ID: 8714758

Claim:
A light trap for a poultry house, the trap comprising: a plurality of panels having a length and a width, wherein each of the panels defines a waveform for at least a portion, the waveform extending in the width direction of the panel, wherein the plurality of panels are spaced a distance D apart such that their waveform portions define a plurality of non-linear air-passages for allowing an airflow (AF) into or out of the poultry house at a velocity (V), wherein the air-passages have a resistance to airflow (RAF) and a light reduction factor (RFL), wherein each of the waveform portions has a plurality of light deflective walls (LDWs) oriented non-parallel to the direction of the waveform, and wherein the LDWs protrude outward from the panel and each LDW has at least two surface areas substantially perpendicular to the panel adapted to block light from advancing beyond said LDW.
