Abstract: The present disclosure provides a wide color gamut LED package structure and production method thereof, comprising a bracket, wherein an LED chip is mounted on a top surface of the bracket. A packaging mechanism is sleeved on the LED chip and includes a packaging glue, and the packaging glue is mixed with a red phosphor, The LED chip includes a multiple quantum well layer for generating light of different wavelengths. By integrating blue light and green light multiple quantum well layers in the LED chip, and combining with external red phosphor, when an LED lamp bead is electrified and emits light, the NTSC color gamut of spectrum composed of the blue light and green light of the chip, and the red phosphor is higher than that of the blue light excitation phosphor. By directly generating multi-color lights on a single chip, the chips used are reduced, thereby reducing costs.

Abstract: A new type of LED light, related to a technical field of LED, including a cup body. The cup body includes a first light-emitting assembly, a second light-emitting assembly and a third light-emitting assembly. The first light-emitting assembly is used to emit green light, the second light-emitting assembly is used to emit blue light, and the third light-emitting assembly is used to emit blue light. A first phosphor layer is provided on the second light-emitting assembly or the third light-emitting assembly, so that the blue light emitted by the second light-emitting assembly or the third light-emitting assembly is transformed into red light after passing through the first phosphor layer. The present disclosure emits red light through a combination of blue light and a phosphor layer, replacing traditional red lights, improving the performance of the new type of LED light and reducing costs.
