A light source assembly and a method of manufacturing the same

Abstract

The application discloses a light source assembly and a manufacturing method thereof, and relates to the technical field of LED display. The light source assembly comprises a substrate, at least one light emitting unit, the light emitting unit is arranged on the mounting surface of the substrate, the light emitting unit comprises an encapsulation layer, a first dam and at least one light emitting chip, the first dam is enclosed at the outer periphery of the light emitting chip, and the encapsulation layer covers the light emitting chip in the first dam; the encapsulation layer comprises a fluorescent film layer, a first gap is formed between the side surface of the fluorescent film layer and the inner side wall of the first dam, and the first gap is filled with a light blocking glue layer, so that the light source assembly emits light only from the surface of the fluorescent film layer. The uniformity of the concentration of the fluorescent powder in the fluorescent film layer is good, and the consistency of the light emitting chroma between different light emitting units is improved. The first gap is filled with the light blocking glue layer, light emitted by the light emitting chip is prevented from leaking out from the edge of the fluorescent film layer, and the light emitting effect is improved.
