Depression is a mental illness with high prevalence and recurrence. It will cause the low life quality and the problem such as cognitive impairment and lead to suicide when the disease is severe. Research has shown that less melatonin levels of the organism can induce the depression. This article mainly introduced the relationship between the secretion of melatonin and light intensity with spectral distribution, the effects of light therapy for depression. According to the LED spectral adjustable and intelligent, we integrate the different dimensions of light to bring people comfortable experience and create light environment conducive to the physical and mental health for the treatment and prevention to relieve the depression well.
