Zusammenfassung: | The invention relates to an LED device with a large light-emitting angle and a module. The invention relates to an LED device with a large light-emitting angle and a module. The LED device with the large light-emitting angle comprises a substrate, an LED chip, a fluorescent glue layer and a shielding layer, wherein the LED chip is electrically connected to the substrate; the fluorescent glue layer wraps and covers the light-emitting surface of the LED chip; the shielding layer tightly covers the top surface of the fluorescent glue layer, so that a part of light emitted by the LED chip is reflected to the side surface to be emitted; the interface between the fluorescent glue layer and the shielding layer is a curved surface. According to the LED device with the large light-emitting angle and the LED module with the large light-emitting angle, the fluorescent glue layer and the shielding layer are arranged to be of the curved surface structure, the binding force of the interface is increased, more light rays re |
