Abstract
An illumination device and a manufacture method thereof are provided. The illumination device includes a base, an illumination chip, and a sealant. The illumination chip is disposed on the base while the sealant covers the illumination chip. The sealant has an outer surface which includes an inner circular convex and an outer circular convex surrounding the inner circular convex. The inner circular convex encloses a space with a narrow bottom and a wide opening. The illumination chip is disposed within a projective area of the inner circular convex. A part of the light emitted from the illumination chip is directly reflected from the inner circular convex to the outer circular convex and directly leaves the sealant from the outer circular convex.
