  • Patent number: 10895362
    Abstract: A lighting device may include a plurality of light sources which are disposed on the circumference of a concentric circle, a light guide which surrounds the light sources and is disposed adjacent to the light sources, and a cover member which surrounds the upper surfaces of the light sources and the upper and side surfaces of the light guide. The light guide has a first surface in the light source direction and a second surface in a direction opposite to the light source which have an inclination with respect to the optical axis of the light emitted from the light sources. The cover member has a light transmitting pattern in a light diffusion region facing the upper surface of the light guide.
