Abstract

The invention relates to the technical field of LED packaging, and relates to a thermal insulation layer reflection type quantum dot LED packaging device and a lamp. The heat insulation layer reflection type 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, heat-insulating adhesive layer, quantum dot layer and barrier water and oxygen layer, a heat-insulating adhesive layer is arranged between the quantum dot layer and the fluorescent coating, in order to protect the quantum dots, a layer is provided between the quantum dot layer and the fluorescent coating There is a heat-insulating adhesive layer, and at the same time, a reflective material for reflecting light is arranged inside the heat-insulating adhesive layer. The reflection of the reflective material can improve the light-emitting angle of the LED chip, so that the light can be emitted at a larger angle. The reflection of the reflective material can Disperse the central beam of light to make the distribution of light more uniform and improve the lighting effect; the lamp includes a lamp holder, a lamp pole, a lamp cap and a thermal insulation layer reflective quantum dot LED packaging device. Compared with the prior art, the lamp has the above advantages.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to a thermal insulation 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, it has become an important technical problem to be solved by those skilled in the art to provid...
