The present application discloses a light source device and a light string. The light source device comprises a transparent protective cover, an LED module and a refraction lens, and the transparent protective cover has an accommodating cavity with an opening at one end; the LED module is arranged in the accommodating cavity, and is used for emitting light; the refraction lens is covered above the LED module, a side of the refraction lens close to the LED module is an incident surface, and a side of the refraction lens away from the LED module is an exit surface, and the exit surface is used for refracting light passing through the exit surface. According to the application, the light emitted by the LED module is refracted by the refraction lens and diffused around, thus realizing wide-area illumination. It can achieve the maximum of 360° light emission and improve the decorative effect.
