Ocean Park’s new animal attraction and associated facilities, a shelter for meerkats and tortoises at Whiskers Harbour, allow visitors to enjoy the African wildlife experience in the unique exhibit. The venue incorporated the circadian lighting concept into the intelligent control system. In the daytime, the cool-color temperature of the light panel acts as daylight penetration through the ceiling module; while the warm-color temperature of the downlight is switched on at night time to support special events held in the park. In addition, we designed animal-oriented lighting with a very low lighting intensity to minimize the interruption to the life cycle of the animals.
