Abstract

The invention relates to an LED packaging structure having transparent conductive material. The transparent conductive material comprises a first portion filling connecting holes and shallow trenches, a second portion partially filling deep trenches, and a third portion projecting from a second side opposite to the deep trenches, and has a first conductive path including the second portion and the first portion to connect third and third electrodes and a second conductive path including the third portion and the first portion to connect second and fourth electrodes; the projecting third portion match in shape with concave portions of the deep trenches not filled with the transparent conductive material. The LED packaging structure enables a lamp string with multiple LED chips in series and parallel connection and is easy to replace, and a method is simple.

Description

technical field [0001] The invention relates to the field of solid-state lighting materials, in particular to an LED package structure and a light string structure formed therefrom. Background technique [0002] LED is a solid-state semiconductor device that can directly convert electrical energy into light energy. Compared with traditional incandescent lamps and fluorescent lamps, white LEDs have the advantages of low power consumption, high luminous efficiency, long service life, energy saving and environmental protection, so they can not only be widely used in the field of daily lighting, but also enter the field of display equipment. [0003] The current LED packaging is mainly a COB (chip on board) packaging structure. This kind of packaging mostly fixes multiple LED chips on the substrate, connects them in series and parallel through wire bonding, and then performs overall sealing with resin. In this kind of package structure, once an LED chip in the package is damage...
