Abstract: A lighting device including a light converting structure, a light accommodating structure, and a lighting device that utilizes a light converting structure and/or a light accommodating structure to obtain a thinner configuration. The light converting structure includes a bottom conical recess to accommodate a light source, and a top conical recess to distribute the lights emitted from the light source. The light accommodating structure includes a through hole with a small opening and a large opening. A light source is accommodated in the through hole at the large opening, and the lights emitted from the light source output at the small opening.
