The invention provides an optical component, a manufacturing method of the optical component and a light-emitting device comprising the optical component; the optical component comprises a membrane, a fluorescent material layer jointed with the membrane and a lens layer jointed with the fluorescent material layer, wherein the fluorescent material layer is located between the membrane and the lens layer; and the surface, jointed with the fluorescent material layer, of the lens layer is used as a light-emitting surface, so that external incident light (such as blue light emitted by an LED (light-emitting diode)) penetrates through the lens layer and then stimulates fluorescent materials in the fluorescent material layer to generate light rays with an expected optical effect. By applying an IMD (In-Mold Decoration) process to a non-contact encapsulation of the LED, the usage of the fluorescent materials is reduced and the cost is lowered; at the same time, the fluorescent materials are far away from the a light-emitting component and are prevented from being affected by the heating of the light-emitting component, so the service life of the optical component is prolonged.
