Abstract

The invention relates to the technical field of LED packaging, and relates to a fluorescent layer reflective type LED packaging device and a lamp. The packaging device comprises a substrate and an LED chip arranged on the substrate; a fluorescent layer, a thermal insulation adhesive layer, a quantum dot layer and a water oxygen barrier layer are arranged on the top of the LED chip in sequence; the thermal insulation adhesive layer is arranged between the quantum dot layer and the fluorescent layer; for protection quantum dots, the thermal insulation adhesive layer is arranged between the quantum dot layer and the fluorescent layer; meanwhile, a reflective material used for reflecting light rays is arranged in the fluorescent layer; by virtue of reflection of the reflective material, the light output angle of the LED chip can be enlarged, the light rays can be scattered with an larger angle, a central light column can be scattered by virtue of reflection of the reflective material, and light ray distribution can be more uniform, so that the lighting effect can be improved; the lamp comprises a lamp holder, a lamp pole, a lamp head and the fluorescent layer reflective type LED packaging device; and 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 fluorescent layer reflective LED packaging devices and lamps. 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 provide a fluorescent layer...
