This site is located in Wu Han China, which is influenced by coronavirus, Chinese government decided to build some temporary epidemic hospitals to heal patients. As temporary hospitals, they were equipped with electrical, watery and ventilated pipelines difficultly and wastefully. In our design scheme, we hope these hospitals could receive and cure patients rapidly, so the sunlight is very significant.We also hope patients can collect sufficient sunlight. Different situations can form different lighting atmospheres to help them recover more rapidly.Aimed at these anticipates, we designed a device of gathering sunlight and connect patients' demands to form different lighting environments. It gathers sunlight by dome skylight and Fresnel lens which are made of glass and polyolefin material. What' s more, light-sensitive senor can react the direction of spot of sunlight and rotate Fresnel lens to the most appropriate position. Then the sunlight is reflected by mirror surface to triple prism and dispersed into different light spectrums to corresponding light area. Finally, they are controlled by suction light piece to form different lights to diffuse reflector to give out lights.We are decided to design a practical device to help doctors and patients to improve treatment success rate, so we also calculated the cost of the device, which can be adopted and carried out economically and conveniently. Nowadays, not only coronavirus has broken out, but also many patients need nice environment to be healed. We strongly believe our scheme can help all of temporary hospitals to pull through.
