The device comprises a substrate, chips and a packaging layer, wherein there are two or more than two chips; the substrate is provided with corresponding quantity of installation grooves, the chips are installed in the corresponding installation grooves, and through holes are arranged between adjacent installation grooves; and the packaging layer runs through the through holes and the installation grooves are filled with the packaging layer, the chips are coated with the packaging layer, and the upper surface of the packaging layer is provided with a fluorescent powder layer. The LED package device is simple in packaging operation and high in packaging efficiency; and moreover, the packaging layer is not easy to shed, and the packaging is firm.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED packaging device and a packaging method thereof. Background technique [0002] Light-emitting diodes (LEDs) have been widely used in technical fields such as architectural decoration, backlight, automotive headlights, indoor and outdoor lighting, and traffic signals since they were extensively studied. Due to the wide range of applications, the packaging devices of light-emitting diodes (LEDs) must meet the requirements of different environments. [0003] Today, PLCC / EMC stent packaging is the mainstream LED packaging structure in the market, which includes copper, plastic and plastic processing and forming stent cups. The bottom of the stent cups has a silver surface treatment to enhance reflection and improve packaging efficiency. However, in high-temperature and high-humidity environments, LED devices packaged in PLCC / EMC brackets are prone to failure. The main manifestation is tha...
