- According to the criteria of PD diagnosis of the MDS, PD patients were selected as the research object. The clinical symptoms of PD patients were consistent with Hoehn and Yahr stages 2-3.
- All PD patients have maintained stable drug treatment for at least one month, signed clinical informed consent and agreed not to adjust drugs throughout the light test and follow-up period.

Interventions
The light box uses a spectrally transparent prism diffuser, which can block ultraviolet rays, but will not affect the quality of the filtered light and will not turn yellow. The distance between the light box and the patient should not exceed 65cm.PD patients are selected for light intervention of different intensities. The experimental group is treated with 10,000 Lux intensity. The treatment time is 1 hour each day from 08:00-11:00 in the morning and 17:00-19:00 in the afternoon lasting for a month. The patient is asked to move under the light source, but should not fall asleep.
