Abstract

The invention relates to the technical field of light bars, and more specifically, relates to a chips on board (COB) light bar and a manufacturing method thereof. The COB light bar comprises a secondsilica gel part and a light panel arranged in the second silica gel part, the light panel is provided with chips, and the chips are covered with a first silica gel part. It is guaranteed that the theCOB light bar has certain overall dimensions, the dosage, thickness and width of silica gel are ensured, as the COB light bar is composed of the multiple chips, the light mixing effect is very good, so that the color temperature of the COB light bar can be controlled, the color consistency is guaranteed, and the COB light bar has a novel appearance and certain water resistance and dust preventioneffects. Continuous production is realized, the production efficiency is improved, the chips are directly delivered to the application production end, the packaging section is eliminated, batch production is achieved, the cost is reduced, the application range of products is expanded, the shearing position of scissors can be seen by a visual window, the light bar can be cut and used at will, convenience is realized, and the application range of the products is expanded.

Description

technical field [0001] The present invention relates to the technical field of light bars, and more specifically, to a COB light bar and a manufacturing method thereof. Background technique [0002] LED is the abbreviation of English light emitting diode (light emitting diode), and its basic structure is an electroluminescent semiconductor material. LED light strips are also called LED flexible light strips, LED light strips, LED flexible light strips, and LED soft light strips. LED light bar refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board, which is named for its product shape like a strip. Because of its long service life (generally, the normal life span is 80,000 to 100,000 hours) and environmental protection, it has gradually emerged in various decoration industries. [0003] The existing COB light strips are all made of glue-dropping process, which are all natural leveling methods, irregular, uneven light emission, and ar...
