Abstract

The invention relates to the field of LED packaging technology, and relates to quantum dot layer reflective quantum dot LED packaging devices and lamps. The quantum dot layer reflective quantum dot LED packaging device includes a substrate and an LED chip arranged on the substrate. The top of the LED chip is sequentially provided with Fluorescent coating, thermal insulation glue layer, quantum dot glue layer and water and oxygen barrier layer. There is a thermal insulation glue layer between the quantum dot glue layer and the fluorescent coating. In order to protect the quantum dots, between the quantum dot glue layer and the fluorescent coating There is a thermal insulation glue layer between them, and a reflective material for reflecting light is provided inside the quantum dot glue layer. The reflection of the reflective material can improve the light emission angle of the LED chip, so that the light can be emitted at a larger angle. The reflective material The reflection can disperse the central light column, make the light distribution more uniform, and improve the lighting effect; the lamp includes a lamp holder, a lamp pole, a lamp head and a quantum dot layer reflective quantum dot LED packaging device. Compared with the existing technology, the lamp has the above-mentioned Advantage.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to a quantum dot layer 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 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 quantum dot LED packaging device and lamp with better color r...
