Description

Technical Field

[0002] At present, COB (Chip On Board, integrated surface light source technology) LED lamps are becoming more and more popular in the market, but the existing lamps generally solder the COB light source on a conventional bracket, which requires secondary welding, or the conductive contacts are hard contacts, which will cause poor contact after long-term use, and make the distance between the lamp bead and the surface of the PCB board a bit far, resulting in a large amount of light loss. In addition, the traditional lamp bead fixing seat has low variability and requires a high mold cost. For this reason, a lamp bead fixing seat with a novel structure is needed to reduce the distance between the lamp bead and the surface of the PCB board, thereby reducing light loss, and does not require secondary welding, and reduces mold costs.
