Description

Technical Field

[0001] The utility model relates to an improved structure, in particular to an improved structure of an LED lamp tube. Background Art

[0002] The internal structure of the existing double-sided power-input LED lamp tube is mainly that a plurality of LED lamp beads are bonded on a substrate, and a driver with a plurality of electronic parts is bonded to one side of the substrate. A set of covers are bonded to the two sides of the LED lamp tube by adhesive and two lamp pins with power input are provided on the outer side. The driver and the adjacent set of covers and the lamp pins at the other end of the substrate and the other end of the substrate are respectively soldered to the driver and the adjacent lamp pins and the other end of the substrate and the adjacent lamp pins by two sets of two wires. Since the driver often fails to start due to capacitor damage, the driver is bonded to the The surface of one side of the substrate and the cover are glued to both sides of the LED lamp tube, so the LED lamp tube cannot be disassembled for maintenance and is generally discarded directly, resulting in material waste and increased garbage, which is not environmentally friendly. In addition, since the driver is welded on the surface of one side of the substrate of the existing LED lamp tube and occupies a space, it is impossible to weld multiple LED lamp beads there. The substrate without LED lamp beads becomes dark and cannot emit light, affecting the brightness of the LED lamp tube. However, the same problem will occur in LED lamp tubes with single-side power supply, which greatly reduces its practicality. This is a point that technicians in this field and consumers are eager to break through. Utility Model Content
