Abstract

The invention relates to the LED light source technical field, and especially relates to an LED lamp bead and an LED light source; the LED lamp bead comprises an LED chip and a quantum dot film; the LED chip emits light; the quantum dot film is located in the main light emitting direction of the LED chip, and comprises a quantum layer formed between two transparent film layers; the quantum layer is a film formed by hot pressing a mixture of evenly mixed quantum dots and a packaging glue; the quantum dot film is formed by evenly mixing quantum dots, the packaging glue and acrylic powders, and hot pressing the mixture; the LED light source employs said LED lamp beam. The LED lamp bead and the LED light source are wide in color gamut scope.

Description

【Technical field】 [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp bead and an LED light source. 【Background technique】 [0002] LED lamp beads are widely used, but people have higher and higher requirements for the color gamut of LED lamp beads. However, the existing LED lamp beads generally use "blue LED + yellow phosphor" to induce white light, and its color gamut can no longer meet people's needs. [0003] Therefore, how to provide an LED lamp bead with a wide color gamut has become a demand for the development of the LED technology field! 【Content of invention】 [0004] In order to overcome the technical problem of the narrow color gamut of the LED lamp bead, the present invention provides an LED lamp bead and an LED light source with a wide color gamut. [0005] The solution of the present invention to solve the technical problem is to provide an LED lamp bead, the LED lamp bead includes an LED chip and a quantum dot diaphra...
