Abstract
A light fastness/weather resistance accelerated test apparatus, including a test tank having a discharge duct, a light source at the center of the test tank with a sample rotating frame rotatable around the light source and a black panel thermometer mounted on the sample rotating frame. A sensor on the sample rotating frame senses the temperature at the position of a sample. An air flow regulator is provided on the test tank, a blower is mounted for discharging air into the bottom of the tank, and a circulating duct is connected between the air flow regulator and the blower. A damper in the air flow regulator is movable to open the inside of the tank to the discharge duct or to direct air from within the tank into the circulating duct. An air mixer has a further damper and a bypass opening into the air flow regulator. The further damper is controlled to direct air through the bypass in response to the temperature outside the apparatus.
