LED DEVICE WITH A LARGE LIGHT EMISSION ANGLE

Abstract: a light-emitting diode (led) device and module with a large light emission angle include a substrate, an led chip, a fluorescent adhesive layer, and a shielding layer, where the led chip is electrically connected to the substrate; the fluorescent adhesive layer wraps and covers a light-emitting surface of the led chip; the shielding layer tightly covers a top surface of the fluorescent adhesive layer enabling part of the light emitted by the led chip to be reflected to the side surfaces of the fluorescent adhesive layer and emitted out from the led device with a large light emission angle; and an interface between the fluorescent adhesive layer and the shielding layer is a curved surface.
