Abstract

The invention relates to the technical field of LED package, and relates to a reflection type quantum-dot LED package device and a lamp. The reflection type quantum-dot LED package device comprises asubstrate, a first LED chip, a second LED chip, a quantum-dot glue layer and a reflection layer. By arranging the second LED chip, the service lifetime of the reflection type quantum-dot LED package device can be greatly prolonged; the reflection layer is arranged between the quantum-dot glue layer and the first LED chip, the light giving-out angles of the first LED chip and the LED chip can be expanded by dodging operation of a reflection substance, so that light rays can be scattered at a larger angle; and meanwhile, a central optical column can be scattered by the reflection substance, thelight ray distribution can be more uniform, the light rays uniform irradiate the quantum-dot glue layer, the color development effect is improved, and the service lifetime of a quantum dot in a central region can be greatly prolonged. Compared with the prior art, the lamp has the advantages.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to a reflective quantum dot LED packaging device and a lamp. Background technique [0002] In recent years, the use of LEDs as backlight units for liquid crystal display devices such as televisions and monitors has been rapidly developed. LEDs have become the mainstream of light sources for various purposes such as light sources for backlight units or light sources for general lighting or lighting. The LED is used in the form of a package by mounting a semiconductor-based first LED chip on a substrate and coating the semiconductor-based first LED chip with a light-transmitting resin, and the light-transmitting resin for the LED package may include phosphor of the desired color of output light. [0003] However, the color rendering effect of LEDs in the prior art is poor. [0004] Therefore, providing a reflective quantum dot LED packaging device and lamp with better color r...
