Problems solved by technology

[0003] In the traditional LED packaging structure, the bottom plate used by the bracket is a flat structure, and the chip is fixed on the bottom of the bracket for operation. At present, bowls and cups all use this structure. Due to the limitation of materials, the brightness improvement of this structure depends entirely on the improvement of the chip. It is difficult for the bracket to adjust Brightness is improved, resulting in lower luminous efficiency and limited range of applications

Abstract

The invention discloses an LED packaging structure with a 3D bracket. The LED packaging structure comprises the 3D bracket with a cup-shaped structure, and a projection which is fixed on the inner bottom surface of the bracket for placing an LED chip and increasing integral light output efficiency of the LED chip. According to the LED packaging structure, through utilizing the 3D bracket, height of the LED chip in the bracket is increased, thereby increasing integral light output efficiency of the LED chip and improving integral brightness of an LED light source. The LED packaging structure overcomes a technical problem of high difficulty in using the bracket for improving brightness of the LED light source because of limitation of a bracket material. Because a quantum dot fluorescent material can be used in the LED packaging structure according to the invention, high-color-gamut display application or high-color-displaying illumination application can be realized. Furthermore the userange of the quantum dot and the related LED is expanded.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting. More specifically, it relates to an LED packaging structure with a 3D support. Background technique [0002] LED is a semiconductor light-emitting device, which is widely used as indicator light, display screen and so on. White LED is known as the fourth-generation lighting source to replace fluorescent lamps and incandescent lamps. LED has changed the principle of tungsten filament luminescence of incandescent lamps and three-based toner luminescence of fluorescent lamps. It uses electric field luminescence and has the advantages of high luminous efficiency, no radiation, long life, low power consumption and environmental protection. A traditional way to form a white light LED is that a blue light or ultraviolet chip excites the phosphor attached to the chip, and the light emitted by the chip under electric drive stimulates the phosphor to produce visible light in other bands, a...
