Title:
LED LIGHTING STRIP AND THE MANUFACTURING SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/243673
Kind Code:
A1
Abstract:
A light-emitting diode (LED) lighting strip (100) having partial potting and the manufacturing system (300) of the LED lighting strip (100) are provided. The LED lighting strip (100) has a flexible printed circuit board (FPCB) (122) with a plurality of LED modules (120) thereon. Each individual LED module (120) comprises one or more LED chips (121). The LED lighting strip (100) is protected by an encapsulant (123) disposed above the LED chips (121). The system (300) includes an upper cover processing subsystem (301), a circuit board processing subsystem (302), and a baking oven (360). The upper cover processing subsystem (301) includes a first extrusion machine (310) for making the thermoplastic glue (130), a pit forming tool (320) to obtain an upper cover (123A), and an adhesive application tool (330). The pit forming tool (320) is configured to form slots (124A) on the bottom side of the thermoplastic glue (130), thereby the upper cover (123A) covers the FPCB (122) with air gaps (124) arranged above the LED chips (121) for improving a perceptual performance on chromaticity coordinates.
