To ensure the comfort and welfare of animals in the isolation chamber, chambers are equipped with an automatic light control system and a television entertainment system. The automatic light control system includes adjustable illumination lamps and a lampshade. The adjustable illumination lamps are composed of three cold light lamps and their conditioners. The illumination system can be used to meet the needs of the animal's physiology, as well as experimental requirements. The television entertainment system consists of a flat television and two transparent television installation boxes fastened to the front door by fixing screws. The animal is able to watch television programs that are controlled by the central control room. The purpose of this design is to reduce depression associated with the space constraints faced by the animals and to ensure the ethical treatment of the animals.
