Abstract

The invention relates to the LED packaging technical field, and relates to a quantum dot layer reflection type LED packaging device and a light fixture; a fluorescent glue layer, a heat insulation glue layer, a quantum dot glue layer and an obstruction water oxygen layer are arranged in sequence on the top of the LED chip; the heat insulation glue layer is arranged between the fluorescent glue layer and the quantum dot glue layer so as to protect the quantum dots; the heat insulation glue layer is arranged between the fluorescent glue layer and the quantum dot glue layer, and a reflection material used for reflecting lights is arranged in the quantum dot glue layer; the reflection material can reflect lights so as to improve the LED chip light extraction angle, so the lights can be radiated in the maximum angle; the reflection material can reflect the lights so as to split the central light column, so the lights can be distributed more evenly, thus improving the illumination effect; the light fixture comprises a lamp holder, a lamp pole, a lamp cap and the quantum dot layer reflection type LED packaging device; the light fixture has said advantages when compared with existing lamps.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to a quantum dot layer reflective 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 LED chip on a substrate and coating the semiconductor-based LED chip with a light-transmitting resin. The light-transmitting resin for the LED package may include Phosphor of desired color. [0003] However, the color rendering effect of LEDs in the prior art is poor. [0004] Therefore, providing a quantum dot layer reflective LED packaging device and lamp with better color rendering effect has beco...
