    摘要： A light emission device comprises a light source unit for emitting light at wounded skin and a control unit for controlling the light source unit. The light source unit includes: a substrate; one or more first light sources which are provided on the substrate and which emit first light having a blue wavelength band; and one or more second light sources which are provided on the substrate and which emit second light having red to near infrared wavelength bands. The first light and the second light have different skin penetration depths according to the wavelength.
