A solid illumination device includes a light emitting module (30), a heat sink (20), a plurality of supporters (25) and a plurality of optical protrusions (40). The light emitting module includes a plurality of printed circuit broads (34) and a plurality of point light sources (32) electrically connected to each of the printed circuit broads. The heat sink includes a substrate (21) which has a supporting surface (210). The supporter has slanted side faces (250b, 250c). An acute angle theta is formed between each of the side faces and a normal line F of the supporting surface. The optical protrusions are located on the supporting surface of the substrate. The point light sources are located on the side faces and a portion of light emitted from the point light sources is irradiated downwardly towards the supporting surface and reflected by the optical protrusions.
