Modularized LED lamp strip and processing method thereof

Abstract

The invention discloses a modularized LED lamp strip and a manufacturing method thereof. The LED lamp strip comprises a positive pole metal wire and a negative pole metal wire, wherein the positive pole metal wire and the negative pole metal wire are connected with the input end of a rectifier. The LED lamp strip further comprises a positive pole metal base line and a negative pole metal base line, wherein the positive pole metal base line and the negative pole metal base line are connected with an LED chip and the output end of the rectifier, the positive pole metal wire, the negative pole metal wire, the positive pole metal base line and the negative pole metal base line are distributed in parallel, multiple plastic bases transversely wrapping the positive pole metal wire, the negative pole metal wire, the positive pole metal base line and the negative pole metal base line are arranged, the upper portions of the plastic bases are provided with a containing groove used for containing the LED chip, the bottom of the containing groove is exposed so that the positive pole metal base line and the negative pole metal base line of an electrode of the LED chip can be welded, and a light-pervious layer is further encapsulated on the surface, in the containing groove, of the LED chip. By means of the technical scheme, the height of an LED lamp can be effectively reduced, processing is easier, processing efficiency is higher, production cost is effectively lowered, troubles of externally connecting a power supply line are omitted, and application approximates to perfectness.

Description

technical field [0001] The invention relates to the technical field of LED packaging, refers to patch LEDs, and in particular to a modular patch LED light bar structure. Background technique [0002] The existing SMD LEDs are mainly pasted on the surface of the PCB circuit board to achieve light emission, which is suitable for SMT processing and reflow soldering. This method of SMD LEDs solves the problems of brightness, viewing angle, flatness, reliability, The problem of consistency, compared with other forms of LED packaging devices, it has the advantages of strong vibration resistance, low solder joint defects, good high-frequency characteristics, etc., and can package multiple LED chips in a small area. Compared with the LED packaged on the surface of the PCB circuit board, it can reduce the size and weight of electronic products, and finally make the application more perfect. However, this kind of PCB circuit board patch LED also has complex processing technology, whi...

AI Technical Summary

Problems solved by technology

However, this kind of PCB circuit board patch LED also has complex processing technology, which leads to high processing difficulty and low efficiency. Because it needs to be applied to PCB circuit boards, it not only increases the thickness of the LED, but also increases the production cost. In addition, the external power supply connected to the input terminal of the rectifier The wire must pass through the entire lamp bracket to realize the power supply, especially for the strip-shaped LED fluorescent lamp, which undoubtedly increases the difficulty of processing
