Zusammenfassung: | A small-size LED packaging structure for enhancing a Sight emitting angle includes an opaque base and at least one light emitting chip. The light emitting chip is installed on the opaque base, and the opaque base includes a transparent sidewall disposed around the base and a concave-cup space, and the transparent sidewall is formed by a molding method, and the concave-cup space is filled with a packaging gel by a dispensing method, and the packaging gel is doped with at least one phosphor powder. Therefore, the transparent sidewall can increase the light emitting angle to 140°~180° and reduce the amount of internal reflected light significantly to avoid the occurrence of a yellow ring phenomenon, and the phosphor powder can enhance the color manifestation and the color gamut. |
